Hopefully between the title and the first shot, this is enough to draw some interest in my build.

All builds typically start because something broke. In this case, the F1A and 10lbs of boost didn’t attack the stock shortblock. I was out on the backroads in October 2012 and was leaving a little “advertising”. Needless to say, the clutch a little warm (AKA really hot) and wouldn’t engage in most gears. The clutch was shot. I was able to finally get the car in 2nd gear and drove it to the shop. It was a long 7 miles at about 25mph. This is where this build got out of hand.

Advertising (end of the clutch):

https://farm5.staticflickr.com/4284/...aa877c37_b.jpg

At this point, I probably should have started the build thread, but I ended up doing it towards the end of the build. Or let me rephrase this, at the end of this phase of the build. I’m sure it will never end. I have been catching hell from a bunch of people to get a build thread going, so here we go.

I will emphasize that this was one of the largest pain in the ass projects I have ever taken on. Be forewarned, I will not hold back any hard feelings I have experienced towards the build, or vendors that I bought stuff from. Hopefully that will be thoroughly documented in the build thread. I will speak the truth and let you know exactly what I thought of them! You can learn from my mistakes!

Background on me: I am an Electrical Engineer that provides construction services to an extremely difficult industrial client. I know and understand how important good communication is and I also take pride in being organized and detail oriented. This was the beginning of my frustration through this project. It has been over a year of nothing but pitfalls, stress, disappointment, but hopefully an end in site.

Sit back and enjoy reading through my project. I am going to throw up information on the car to help with a bunch of the questions then jump into more specifics on the car and build. I have sat down to type some of the build, and I get lost each time when getting into. There is too much to try to document on these. I highly recommend starting these when you start the project. The pictures and write-up will be in no particular order.

The car is a 2001 Sunset Orange Metallic Trans Am WS6, six speed car. I bought the car in 2008 with a D1SC Procharger kit on the car. Eventually, I swapped to an F1A head unit. The car made 566rwhp / 525rwtq on a Dynojet with the D1SC. I never made it back to the dyno with the F1A. I had purchased a MWC Fab 9” and other rear suspension supporting modifications.

Right after I took the clutch out of my car, I rode in a buddy’s recently completed (or a 1st phase) Turbo car (LS1Tech Username: Slow94formula) in the fall of 2012 and instantly got the bug for additional power. I was amazed how the power was brought in with a turbo car. I also liked the fact of being able to control the power levels with an electronic boost controller. I quickly decided to ditch the Procharger setup and switch to a turbo setup (sorry No Juice). From there, I decided to start spending money. I purchased a used 417 Motorsports twin turbo kit previously made famous by LS1Tech Username: Fitz98TA. The kit was recently updated with Precision PT6766CEA turbos.

My parents were going to Branson, MO for vacation, so I stuffed their pockets full of cash and asked them to stop in KC and pick up the TT kit. I bought the kit from Skinnies and my Dad thought the LTD was pretty damn cool. Look up threads on this car if you haven't seen them.

Be prepared to spend this kind of stuff, if you start a build like this:

Attachment 607609

I must say that I am pretty fortunate to borrow my Dad’s garage for this build (especially seeing the length the build took due to all the delays). It is the ultimate Shadetree Mechanic shop. It is a heated 4.5 stall garage, that has pretty much any tool known to man, a hoist, a separate stall for his 1968 RS/SS Big Block Camaro, air fully plumbed throughout the entire garage, heat, etc. It is a perfect location to have a build, minus his frustration of losing not only one stall to the car, but another stall for all the parts either going on or coming off. The 68 Camaro was moved to my storage location and the build took over his garage.

First we removed the Procharger kit and sold to help fund the new project. From there, we started mocking the turbo kit on the LS1 to see what sort of mess we were getting ourselves into. We already knew we were going to have to relocate the battery, the fuse panels, modify the brake lines, etc. We found a few other things, but continued on. We pulled the stock LS1 and T56 and sold those.

My goal for the car was to have a car that would maintain street manners, relieve stress by laying a bunch of rubber, but be able to take it on a long cruise. Hopefully we will even be able to retain Air Conditioning with this kit, it has been done before. I plan to take it to the racetrack and see how many passes I can squeeze in before being reminded that I don’t have a cage or bar. The original plan was to have the car torn apart, and put back together by Spring of 2013. Wow, was I wrong on this.

While we had the engine and transmission out, we did the wire mods and painted the engine bay. I would highly recommend painting the engine bay whenever involved with a project like this. It is well worth it. The engine bays are really dull and they come out nice with new paint, especially after a couple of coats of clear. I was able to get in touch with a local body man, and have him spray the engine bay. Thank you to Slow94formula's Dad and thanks to Slow94formula for sanding and taping!

The plan was to change over from a T56 to a 4L80e. My car had a long torque arm and T56 crossmember. I contacted Midwest Chassis to order parts to switch to a 4L80 crossmember and short torque arm. We pulled the third member and had the gears swapped from 3.70 to 3.25 in the MWC Fab 9. I was torn between a 3.50 gear and the 3.25. Ultimately, I wanted to keep the RPMs as low as possible on the street, especially with running E85. I know, I know, I doubt I will be able to keep my foot out of it. One other thing I ordered from MWC, was a mild steel K-member. This was by far the best purchase in terms of simplifying the install. It is unbelievable how much additional room there is without that stock K-member. I was also able to cut weight off the car, although, it is going to be difficult to notice in this full weight street car. Switching from a T56 to a 4L80 requires a shorter driveshaft. I considered having my 3.5" aluminum driveshaft shortened but eventually decided to buy a PST 3" chromoly driveshaft.

The one thing I wasnt going to cut any corners on was fuel. I didnt want this to be the limiting factor on my build. Most of my fuel plans were based on the Mightymouse DIY triple pumps. There is a lot of good information in there. I started by contacting Sho-me-speed and had them put together a Triple in tank Walbro 255 fuel kit with wiring harness and hobbs switch. I was torn between the (2) 400s or the (3) 255s. I knew either way I would be cutting the fuel basket and eventually went with the 255s. The fuel basket is completely gone and About the only thing remaining is the float. I am running a 10AN line from the pumps to the Y-block where it will be split into 8AN lines and ran to each fuel rail. 8AN lines will also be ran out of each fuel rail to the regulator with an 8AN line back to the tank. I am using Fore Innovations F2i Fuel Pressure Regulator and their Inline Modular fuel filter. I have Holley Hi-flow fuel rails and FIC 2000 injectors. I don't plan on letting the car get low on fuel. I understand my car doesn't have a baffled tank and I don't have a fuel basket. I used a 10AN bulkhead to connect the supply hose to the fuel basket. I bought an 8AN Russell quick fitting to connect the return hose to the existing top hat. Pumps #2 and #3 come on with the Hobbs switch.

I suggest drawing a diagram for ordering fittings. This photo is before updating with changes during the build. I will try to get this updated for future reference. Each build will be different but this is a good baseline.

I got in touch with AES and had them build me a 390ci engine. I wanted to keep this very streetable with minimum maintenance. We decided on 10:1 compression based on running E85, although AES frowns upon Pump E85. From there, we went with a set of ported 243 cylinder heads and full forged rotating assembly. We included all the necessary ARP bolts/studs/mains based on the amount of boost I was planning. We went with the typical LS9 head gaskets. I had AES weld 10AN bungs in the oil pan for the oil return lines from the turbos, one on each side of the pan. I used the typical connection near the oil filter for the feeds to each of the turbos. The cam was specified by AES. The valvetrain was specified to match the rest of the engine and nothing big to keep maintenance to a minimum. We had a few lengthy discussions on rocker arms and I ultimately decided to spend some extra money and go with the Crower rockers. I didn't trust the factory rockers, and I have heard nightmares with the Yella Terras. I also had bought a ATI Super Damper, specified at 25% underdrive with A/C. The original plan for the turbo returns was in the timing chain cover. An underdrive pulley was required based on this location but eventually we went with the side of the oil pan. I had AES fire the engine as part of the break in process. My plan is to run Valvoline VR1 20W50 oil.

I purchased a used Kurt Urban Water Vapor System. Purchased a #4AN x 1/8” NPT straight adaptor. Tapped the top of the water pump for the adaptor. Bought a #4AN straight to straight 22” braided line to connect the water pump fitting to the Kurt Urban distribution block. We built a custom bracket for the mounting of the distribution block. One thing to beware of: keep an eye where the throttle bracket goes. You can't put the adaptor in the center of the water pump. I didn't make this mistake, but was warned about it before drilling and tapping the water pump.

Additional underhood pictures will be posted later in the thread.

I also contacted Jake’s Performance about building a Stage 5 4L80 with D3 transbrake. I contacted Madman and got the Madman 4L80 dipstick. I purchased a Speartech wiring harness to convert from a T56 to a 4L80e. I contacted Circle D and ordered a 4L80 LS Pro Series Stage III 258mm 1B torque converter and LS series SFI steel flexplate. We decided on a 3500 stall speed.

I am currently planning on running a stock automatic shifter; found one with only 9000 miles and was in perfect condition. I am keeping the manual console. I installed a piece of sheetmetal to cover the hole from the T56. I really need to find a Trans Am shifter handle as the Camaro one is ass-ugly! I had bought a Grand Am handle and that was ugly too. I haven't removed the clutch pedal yet. The wiring has been removed so the clutch does not need to be pushed in to start. I have a set of Auto pedals but I don't know if I will go through the work to swap them.

There just isn't enough room in the engine bay. I was originally planning to install the transmission cooler in front of the radiator. It really got tight up there with the fans, radiator, condenser, intercooler, overflow, and catch can. We eventually went a different route and remotely mounted the transmission cooler. I bought a Derale 13900 Electra-cool remote transcooler with fan and thermostat and mounted it under the hatch/trunk.

I was planning to run the same driveshaft until I found out it needed to be shorter. The 4L80 will require 3/4" - 1" shorter driveshaft than the T56. I thought about having my original driveshaft shortened but ended up just buying a new one. I don't think it was worth the hassle of shipping it back to PST and having them shorten it. I ordered a 3" Chromoly driveshaft directly through PST. I worked with Cliff on the phone and he had great customer support. Spent plenty of time answering all of my questions.

My specs from ordering driveshafts (straight from PST invoices):
T56 Driveshaft: 45 1/4" seal to center
4L80 Driveshaft: 44 1/2" seal to center

For boost control, I decided to go with a Turbosmart Eboost2 electronic boost controller. I have an individual solenoid for each of the wastegates. I mounted the Eboost2 in the left air vent.
I wanted to replace my Auto Meter gauges that were originally in the center vents. I had a C2 series vacuum/boost, electronic fuel pressure, and wideband A/F ratio gauge. I decided to go with the Zeitronix ZT-2 gauge. My plan was to install this in the car in a location easily visible while watching the road. This gauge allows for fuel pressure, wideband A/F ratio, and vacuum/boost all in the same screen. Unfortunately, I bought one used and it was a 2009 and older model. This does not allow for fuel pressure. I need to send this in to be upgraded to allow all three parameters.

I bought the MSD 8733 2-step and tied that in to the transbrake switch.
I am running an Emblem Pros manual console ashtray switch plate. I have a switch to activate the line lock, the transbrake/2-step, the electronic cutout, and a miscellaneous switch.

I relocated the battery to the passenger rear cubby hole. I bought the BMR battery relocation tray to hold the battery. For disconnecting means, I chose the Flaming River Big Disconnect switch with lever kit. I wanted to try to hide the routing of the lever and decided on a location near the license plate. I don't plan to run the lever on the street and the hole would be covered by the plate. I had a custom "push off" sticker made by slow94formula as well. All of the cables routed from the battery to the switch were routed and hidden behind the carpet.

I bought 1/0 and #2 welding cable for connections between the battery, alternator, starting, and fuse box. I routed the cable through the inside of the fender/rocker similar to the water lines in the Modular Turbo build. The cables were properly connected to kill all power to the car when disconnecting power at the switch.

I had to relocate the fuse boxes to allow for installation of the driver's side turbo. This became interesting. We ended up combining the two fuse boxes into one and relocated under the driver's side headlight where the cruise control box and air pump were. The wires needed to be extended about 12". Good thing we eliminated what was not needed.

The coils also needed to be relocated due to the turbo headers. I bought a coil relocation kit on Ebay and mounted them near the K-member.

My of my largest concerns was trying to keep this thing cool. I plan to drive it as much as possible. I don't want to be limited on hot days (yes, I know, I am in Minnesota). I ran across the Engineered Cooling Products radiator and thought I would give it a shot. It is the same dimensions as the factory radiator and it is still installed in the angled fashion. I also installed a 160 thermostat. For fans, I went with Derale dual puller fans, #16833. This is a shrouded kit and provides 3750cfm of airflow.

I bought a boosted catch can from Mightymouse. I ended up running into trouble finding a location to install the can. I have it mounted near the hood latch.

I am running a Golden Eagle vacuum distribution block. I was also having issues where to install this. I have this installed in the front of the car near the hood latch as well.

The entire brake lines were updated throughout the car. We removed all the existing lines and put new in. We ran a larger line from stock and used the flexible lines. Those made the installation much easier. I previously had an SJM Manufacturing Line Lock in the car. This was relocated to the driver's side frame rail. I also added the SJM ABS delete as I plan to run a 28" rear tire and a 26" front tire. I anticipate I will need a sticky tire based on the horsepower. We installed the proportioning valve near the brake booster.

We modified the exhaust system to tie in the new 3" downpipes that came with the turbo kit. For the time being, we installed a Y-pipe and tied the existing Magnaflow catback in. The car is extremely quiet. I am sure that might end up shocking a few people when it comes alive. I also added a Badlanz HPE 3" cutout just before the rear end. This should also help the car breathe. The exhaust will most likely be modified next summer to help breathe a little more.

Yes, the exhaust looks pretty ratty right now. It will be updated this summer.

I also had not pulled the film off the stainless steel radiator support. I don't have an updated picture with that off.

I hauled the car over to Andy Wicks of Dynotune Speed and Performance for him to work his magic on the car. Andy has quite the resume when tuning high powered cars, especially on ethanol. He is well known for the Mobile Dyno that appeared on The Hot Rod Power Tour as well as many other large events across the nation.

We ran into a bunch of issues while tuning: bad MAP sensor, 1 bad injector, transmission wiring issues, electric cutout issues, pinion angle issues, and finally boost issues.

We thought we were having boost controller issues. We were struggling with my Eboost2 and even swapped to a buddy's head unit. His worked much better but we kept seeing boost fall off bad around 4500RPMs. We ended up changing to a manual boost controller and changed the wastegate plumbing. On a 19psi pull, we were seeing about 10 pounds of boost fall off.

We finally thought, lets try removing the air filter and elbows and see what happens. The boost levels didn't drop like they had previously. We decided to make one final hit and wrapped up with the following numbers:

8lbs: 550hp / 610tq
12lbs: 685hp / 758tq
19lbs: 880hp / 946tq

I would liked to have modified a few settings and tried a few more pulls but we ran out of time. I'm sure there will be another time. I need to get some data from Andy to analyze.

They are pretty serious about this ethanol ethanol stuff in South Dakota

I have a few things to look at based on the dyno numbers. The car is losing power around 5300-5500RPMs and up. I am guessing this is due to the T3 turbines and/or backpressure. Hopefully I can get it all squared away this Spring. I am ready to take it out and have some fun with it.

I took the clutch out of the car on October 6, 2012. The car was tuned and completed and home on December 21, 2013. It was too long of a year. The car only took about two months to put together but the rest of waiting/delays. I have a few minors things to fix this winter to be ready for Spring. I can't wait!

It's about time you start a thread... The 10 bolt is ready to put a whoopin' on ya!

Very cool. In for more.

Heavy H.P. 12-27-2013 10:34 PM

Good God,

What type of numbers do you expect out of this setup (rwhp/ET's)?

I'm in now..............The ZT2 does fuel pressure now ?

I don't think I will be able to hear my car over that howl from the 10 bolt.

Thank you, I am trying to get through as least the overall build. I will continue to expand on it. It is difficult putting together a thread when most of the work is complete.

I just got it back from the first dyno session. It put 880/946 down. Power is falling off around 5300RPMs though. I am guessing I am running into issues/limitations with the T3 turbines/housings. I am going to look into a few things in the Spring and then consider changing over to the T4 housings.

We will have to see what it puts down for ET's. I am afraid to run it across the scale. It is a full weight street car. Iron block, 4L80, twin turbos, 9", A/C, and full interior. It is going to be heavy. I haven't put a cage in so I am going to try some 1/8 mile hits and hopefully don't get told to leave. Once I get it to launch alright, I am going to try to run a full pass.

Yes sir. The User2 input can be used for fuel pressure. Mine was an older model, so I will have to send in. It is $199 including shipping to get it upgraded. I already have the sensors and wired in. It only makes sense to upgrade it. I will have to shoot you a PM with the info.

Very impressive build. What brake line kit did you use? I'd like to replace all of mine front to rear with the flexible hoses as well. Also, how much work did you have to do to the trans tunnel for the 4l80e swap?

dmaxvaz 12-28-2013 01:35 AM

did you end up changing the cam?

Thank you. It was work just getting this thread started and up to date too.

I had a guy come in and run all new lines. Don't quote me on this but I think he switched it all to 1/4" from 3/16". I will try to find out what brand the line was. The guy that did it works for a towing service and updates a lot of the brake systems on their tow trucks. He came in and had the flaring tool and hammered it out in no time. The flexible line was helpful for routing between the brake booster, proportioning valve, line lock, etc all in a small area.

There is a few things that need to be done to get the 4L80 to fit. There are some ears that need to be cut off the transmission. We were able to just take a sawzall and cut those off. The trans tunnel needs to be widened towards the front of the transmission. We were able to use a hammer/maul and pound the tunnel out. Also need to make sure you have enough room for the transmission connector. I will try to remember to take a few pictures of this when I get it back on the hoist.

Nope. I kept the cam that AES spec'd in it. I was scrambling to get it done before winter. I am not sure if I am going to change anything for this coming year or just try to enjoy it for the time being.

I was surprised that the torque numbers I got. I was quite happy with that. It was a little bit of a late bloomer but not too bad. When it starts building boost, the torque comes in very hard.

We will see what happens as we go forward.

i have mine torn down to install a different cam. new one has less duration, more lift, and should make more lowend power. i think you make good tq due to the smaller t3 housings. your #s sound great, and if its streetable, leave it

Badass build! Saved it to my favorites lol
