Hey Folks! Some of you might remember me from this car.

My old 93 Z28



The new car:
2002 Sunset orange metallic z28
117k miles
leather, ttops
A4
Bone stock (than a lid)

298rwhp 323rwtq

://www.youtube.com/watch?v=78wrrTSehug

This is what it looked like when I bought it this spring.



A little tint, some wheels, lowered and a good polish job its easier to look at.



Anyways, on to the fun stuff.

My goals, retain ac, run mid to low 11s in the 1/4, have the fiance not cut my ***** off before the wedding next fall aka: keep this as budget minded as possible. 500rwhp through the 4l60e.

Parts I have:
Huron Speed V2 a/c retaining T4 kit. (all coldside, hot side piping, couplers, clamps and bolts needed)
Intercooler
BOV and turbo blanket
BMR turbo k-member
Founders, LCA's, Relocation brackets, ADJ PHB, SFC's.

Parts I need:
Turbo (leaning towards the On3 76 or 78mm). $400
Derale fans x2 -$300
Wastegate- $350
Oil lines- $160
80LB injectors- $450
Fuel pump- (brand?) ~$250
Pac 1218 springs- $170
Trunion kit- $170
TSP hardened pushrods- $120
Catch can (mighty mouse?)
Head studs?
317 heads?
Timing kit?
Oil pump?

I am thinking of tearing it apart this fall but I don't want the car to be apart still come next spring and summer. I am working out of a single car garage so I'm still debating if I want to pull the motor or leave it in.

I'm not looking to be burning down the town with this car just a fun reliable cruiser.

The car has a rebuilt 4L60e in it that I don't expect to last long with the turbo. Nor the rearend. But those will come with time. I don't intend taking it to the track every weekend and launching it on some et streets.

Once the 4l60e goes boom I plan on swapping to a t56. already did it on my 93 so it should be a breeze.

As for my questions:

Is a new timing set necessary?

Oil pump?

317 heads and head studs?

Can I change the heads with the motor still in the car?

If I keep stock heads can I do the trunion kit and the springs with the heads still attached in the car?

Are the pushrods necessary with me keeping the stock cam?

I plan on only running 6 or 7 lbs of boost to get my feet wet.
Any advice and tips would be great!!!

People have made good power on completely stock long block LS1s for a long time so IMO (not very expert) save the time and money and keep it all stock. Upgrade the pump if you really want to but again I don't think its really needed.

For 500whp I also don't think head studs are needed nor are 317 heads. Nor are pushrods and all that. Trunnions can be done with the engine still in the car, you just pull the rockers off.

I feel like the best bet might just be to bolt everything together and run it on a stock engine for now, then in the future if you want more power go with a 5.3 setup. Its exactly what I intend on doing with my car. As long as the stock engine runs good in the car and doesn't make any weird noises, I don't think throwing all those extra parts at it will gain you much other than longer down times and more up front costs.

Hi buddy. Here are some answers to your questions.

Is a new timing set necessary? No, but a good idea and might as well do cam also if you are going that deep

Oil pump? Same as above^^^

317 heads and head studs? Good idea for more boost later down the road, also do LS7 lifters and new trays if you do heads

Can I change the heads with the motor still in the car? Yes, I did mine in the car. Not as fun to torque but it can be done

If I keep stock heads can I do the trunion kit and the springs with the heads still attached in the car? Yes, they make a special valve spring tool that fits and you would need a adapter to run a air compressor air to the spark plug hole to keep the valves in place while you have the springs off.

Are the pushrods necessary with me keeping the stock cam? Yes especially with aftermarket valve springs and the added pressure of boost.


I will start a turbo build thread on mine soon also once I get some more parts and get addition done to my garage so I have more room.

Can't wait to start seeing your progress.

Thanks Josh! I can't wait to see yours come along too!
So basically not much is needed unless I cam it or for better insurance. I really don't plan on getting much past 6 or 7 lbs until I have a built 5.3 ready to go in.

Yeah that is kinda my plan also. The cam I have is horrible for boost but I am going to piece together the bare bones stuff I need to get the turbo kit on and running then start upgrading from there.

I can guarantee you will not be satisfied with mid 11's with a turbo car.

iTrader: (2)

you can run 11s with just head and cam swap

Just trying to be realistic with my goals. I'm not shooting for the moon. Fastest I have been is 12.7 in my lt1 car.

Id run it bone stock with just the turbo kit and have it safely dyno tuned with 100% meth injection for added safety and a little bit more hp. Keep the rpm's to 6000 or so and it will live. No need to rev the crap out of the stock cam and valvetrain for hp in a boosted app. My last boosted ls car had 170k on it when the blower was installed on a 100% stock engine/trans/rear and I daily drove it for 50k before selling it. It was still running great when sold and the guy drove it home 6 hours away with no issues. Dont beat on it from a long sit at a traffic light with the a/c on in 100 degree heat or any silly **** like that. Id use the extra $ on having the trans beefed up in hopes of making it last and not the engine @ 500rwhp. I did a cam swap on my current car with the old ls1 with 170k on it. I reused the chain and pump with no problems. I didnt want to have to mess with the oring with the pan still attached but since yours will be off Id swap it for the melling high pressure one. No need for the high volume one on a stock app. My melling high pressure pump runs 60-65 psi @ idle in 100 deg heat with 5-w30 oil with no additives. It hits 75psi @ idle when first cranked up until warm. LMK if I can help you any. G.L.

Silly question. ..why build a 5.3 when you can get 6.0 iron for about same price and proly with 317 heads you need??

Turbo (leaning towards the On3 76 or 78mm). $400 [B]the gt45 is also an option/B]
Derale fans x2 -$300
Wastegate- $350 could use xs power to save some money a lot of people use them no issue including me
Oil lines- $160
80LB injectors- $450 [B]siemen deka can be had for a lot cheaper
Fuel pump- (brand?) ~$250 [B]twin 255lph kit wanted
Pac 1218 springs- $170
Trunion kit- $170 not needed but nice upgrade
TSP hardened pushrods- $120 I used my stock ones
Catch can (mighty mouse?) didn't use one
Head studs? if you want the procomp ones are cheap and effective
317 heads? not needed but a nice upgrade to lower comp
Timing kit? New ls2 chain is cheap and why not
Oil pump? depends on the condition of yours

I just got done putting a s475 T6 on a stock LS1 and so far so good. don't skimp on the fuel system. Also add a tranny cooler if you don't already have one to help the 44L60

Also don't forget to budget in for gauges. Three important ones wideband, fuel pressure and boost. Meth on such low boost and just to drive around is not really needed especially on a budget type build.

Depends on the area. Here 5.3s are 450-500, 6.0s are 1000

Thanks SCott5! Do you happen to have a build thread? I'd love to read through it if so.

I'm getting a lot of more positive things about this than I thought I would.

I have been told not to cheap out on a wastegate as the xs power ones tend to have boost creep issues and that's not something I want on a stock bottom end.

There aren't many thread of people boosting a complete stock shortblock so it's hard to see what people have had luck with and what they haven't.

kwrench61

iTrader: (1)

I understand but for that other $500 you get more ci and heads you ultimately want. Seems like a no brainer. I paid $1k for my LQ4 with all accys,harness and pcm and glad i did.

SCott5

iTrader: (40)

I'd rather spend the extra 500 and get a better turbo to make more power.

I don't have a build thread I just have a thread where it's all complete with some pics and a breakdown of the turbo kit components

kwrench61

iTrader: (1)

I understand. Good luck to ya I'll be following too.

Whip_N_01SS

mcalus, I'm currently finishing my HuronSpeed T4 kit with a turbonetics TC78 on a stock ls1 with ls6 manifold (2001). I plan to run low boost with a 255 pump, and 80# injectors. Goals are around 550hp range. I will let you know how it goes once its up and running.

iTrader: (14)

Glad to hear I'm not the only one. Start a build thread I'd love to see the pics of progress! Do you plan on dropping the motor? What else do you need for your build? Also are you a4 or m6?
