My 2000 Trans Am KYTP/PT76GTS/370 build.. IT LIVES!
I figured it was time to start a build thread
Some background info - I purchased my car in 2007 from a member here. It was cam only, cam only/nitrous, and finally heads/cam. It always held its own against some pretty fast cars in the area and i have had no complaints. Then my friend let me drive his turbo 99 Trans am and that was all she wrote Just so happens that a friend wanted my complete running motor, perfect opportunity.
Here are some pics as the car was:
231/237 cam, FAST 90, TFS 215 heads, full exhaust, 9 inch etc 460rwhp/423tq
interior shot: fairly stock except corbeau seats and an AFR gauge lol, i will be ricing it out with more gauges, a 8pt and corbeau harnesses
So the motor came out and went to its new home.
After some thought and debate i scratched my orig plan for aTC78 and decided on the PT76GTS instead:
Got a great deal on a stainless KYTP turbo kit from Sluggish:
I plan to have this recoated and modified to accept a TiAl 44mm wg
After my search for a 6.0 iron block ended with finding a bunch of overpriced scrap locally, i decided to just get a running motor from a local yard. I got this 2005 Lq4 out of a penske truck . $900 delivered, can't go wrong! I will be reusing the block, crank, heads (i plan to send them out) and covers
down to the bare block, this thing was silly clean inside, bearings looked brand new
dropped this off at the machine shop this past friday to get cleaned up.
In the mean time, i just had to mock up the turbo kit
Plan is as follows:
370cid motor - diamond pistons, callies rods, ARP studs (main and head) Built by my friend JnJ speed shop
317 heads - i plan to send them to TEA
undecided on a cam
fuel system - may build my own or just get one of the nasty performance kits
LS6 intake - tried and true
pt76gts/tial wg/kytp hot side
E bay cold side
custom 8pt chromoly cage (local guy is VERY skilled and reasonably priced)
I still need to decide on a clutch. I JUST put a spec 3 in the car at the end of last season. It saw maybe 5k miles, no track runs, a few roll races.. one of the weights came off and made a mess of things -
I will try to update this as much as possible, i plan on making many modifications and beautifying things as well, i have always been a proponent of show and go

Yeah Bill's old setup with the 76/370 was my inspiration. It was the prefect combo for a fun street car. I have not made much progress as of late due to school and my rods being on backorder, but apparently they shipped out yesterday. I also received my pistons yesterday so i plan on taking my block to the machine shop today (machine shop wanted the pistons there when they did the work) SO hopefully the short block will be ready for assembly within the next week.

Sounds good. I'm planning on building a 370 for this car within the next year or so. You using the stock crank? How tight do you plan on twisting this motor? Since you're after a roll racing monster, I'd def. go with a bigger stick than what Bill did in his and get peak power up around 6800-7k rpm. That cam worked well in my 347, but 230s on the intake side for a 370 would work well IMO with a good flowing set of 317s. Plus it would sound cool as ****

Just dropped the block and parts off at the machine shop so hopefully the ball is rolling..
Yes sticking with the stock crank, not sure on what i want to rev it to.. I will have the rotating assembly/rod bolts ect might as well take it to at least high 6XXX - 7. I don't even remember what cam bill was running in that setup, it was ages ago. I was thinking something in the 230's as well for this motor.
I would really like to trap a high 14X. Last year my car weighed right around 33XXlbs with the street wheels on. With the added weight of the turbo kit/iron block (but with the race stars and probably a k member offsetting some) it should still be under 3500lbs.. i hope.

Here is a quick update and I'm sure I will be asking more questions:
Got the block machined and all the engine parts balanced. Everything is ready for assembly and waiting @ the engine builders.
went with Mahle pistons
Compstar rods
ARP main and head studs
ACL bearings
Block cleaned up prior to machining
BMR K member:
I am debating on what cam to go with. There are so many options and it is getting a bit overwhelming. At the top of my list currently is the speed INC "TU2" cam which is a 236/236 .587/.587 112.5 ... Some people have told me that this cam will bleed off boost?
Also i want to begin to put together my fuel system while the engine is being built (a friend is doing it for me, so it is getting done on HIS time)
I want to be able to safely make ~750 rwhp and crank the boost a bit with a 93/race mix
So far i am thinking
-FAST rails
-aeromotive boost ref reg
- 60 or 80 lb injectors (?)
-dual walboros (run one off a hobbs switch? i have heard mixed feelings on this)
- -8 feed with the stock feed as a return
Comments and critiques are welcome and requested

Here is an update.. Finally got motivated to go out to the garage and work on the car with the warm weather. Between school and work haven't had a lot of time lately but now its time to start getting work done, spring is fast approaching!
Goals for this wk -
drop front cradle out and get the BMR k member in
get fuel system hooked up and ready to go
order parts for cold side
harass my engine builder for my short block
Got a fuel system together:
- Lonnies Perfromance "Double Pumper" kit. Dual 340 pumps in the modified bucket
- 8 feed with -6 return
- Fuel lab Fuel pressure regulator
- in line filter
- plug and play wiring harness with hobbs switch to activate second pump @ WOT
- SD 80lb injectors
- Speed INC high flow rails
Also modified the bumper and made brackets for my intercooler:
Just waiting on my engine to be assembled before the real fun begins. Im also thinking about picking up some AFR or TFS heads, my tax return was pretty fat this year

anyways..
got some solid work done last night...
Pulled the front suspension by myself which wasn't much fun, then my friend stopped down when the heavy work was done
got rid of the stock K member, never realized how heavy it is in comparison to the BMR chromoly one. Also painted the A arms and what not with black chassis paint and cleaned 10 years of grime off the rack. My Qa1's look silver again too!
Finished product:
Also cleaned up the turbo kit and mocked it up on a junk block i had laying around
Fuel system install starts Wednesday night
