Default Turbo?

Hi. new to the forum.

I'm fixing to revive my 95 Z28 from the dead, and i was thinking about doing a single turbo setup.
But I was wondering why I don't see very many done to LT1s, even on the fastest LT1s list.
Anything I should know before i start spending money and time :X

Ive seen a few, but there arent alot here. I know of one build in particular, just because I know the guy. Used to be his roomate, and im good firends with his brother (frcefed98, one of the FI moderators is a good firend of mine, his brother is the car thats being worked on). His thread for his build is here:

https://ls1tech.com/forums/showthrea...0&page=1&pp=20

Page 3 has some more pics. He'll probablly be posting more soon, Ive seen the new pics with the coated stuff hung on the car and with all the pipe routing done.

Theres another guy I see posting in this section from time to time. "Dragframe". He has a turbo setup I think, but I dont know the specifics. Theres also a Red LT1 Camaro ive seen in the FI section with a TT setup thats pretty unique. **edit: Intmd8 is the guy I was thinking of for the TT setup. You can find his website and stuff with all the pics**


Turbo setups are alot of work, And if you cant find a kit you need to be decent at doing fab work and welding to get it done. Even if you find a kit, you'll probablly need to do slight modifications to your setup to get it to work, its just the way these things have gone that ive seen. We're planning on doing one for my car, but still in the planning and engine buildup stages. Its alot of little things to get a turbo setup going. If you browse around the Forced Induction section of the forums you'll probablly turn up more information than you can use.

the biggest problem i have found is finding a good way to manage the whole thing.
you pretty much have to step up to a full standalone as there arent many other good options.

another thing i think will be a major problem is space. we all know you can't sit in the engine bay and tinker like you can in older models =/

I suspect the front mounts are more expensive because you have to replace the exhaust manifolds.
As mentioned above, space in the engine bay is at a premium, so anything you add in there makes access to everything more difficult.
The downside to a rear mount is the length of the intake tubing and the oil lines to the turbo.
Any turbo requires major tuning once implemented, plus all the extra items, such as larger injectors, gauges, etc.

you can do plenty to your ol z28 all motor, and still be dependable, not that all turbo's aren't dependable. $3K+ for a turbo setup, you can well work over your motor for that and be real happy.

Heads/Cam + nitrous is a very common and effective direction to go in

i constructed a turbo system for my lt1 a few yrs. back using a holset
turbo, using a scavenge pump for the oil drainback since it was mounted rather low, taking the place where the driver side cat was located, then routed the intake plumbing to a horizontal mounted ic that i made from 2
supra cores, feeding into a k&n plenum intake and 1le elbow. i used
30 lb. svo injectors and a 12:1 fmu at about 8 psi. car ran really strong.
i would have to say as strong or stronger than the 383 with ported lt4 heads
and intake combo i had, although the 383 had th400 and athe turbo was
a t56. but the 383 car was a mid 10's on 175 tb plate shot.
wideband o2's were not as available at the time. but the car stayed together
for over 2 yrs., until the guy i sold it wrecked it.
bottom end was rebuilt with sbc forged pistons and rings, on stock rods and crank, clevite bearings, stock heads and intake.

Megasquirt is a good option to look into. Not only does it eliminate the opti, it also can be used up to 44lbs of boost as you can get a 4 bar map sensor to work with it.

but if u go megasquirt, u might as well go sbc also and use sbc
single plane intake with elbow plenum along with some hi flow sbc heads and a edis 8 for ignition. might as well go better everything.

Why? You don't need some super fancy intake or heads or anything to make more than enough power to be useless on the street.

couldnt hurt
just alot more options for heads and intakes for the sbc
motors, the late model vortec truck engines are also rollers,
and it would bolt in place of a lt1, also it is alot easier to find the 4bolt main
vortec truck engines, just throwing some ideas out there

Im only 19 and have a turbo setup. I honestly still haven't got it together because its been tight lately. I still have injectors, fuel pump, wideband, and intake elbow to buy.

Hopefully soon I will get it done soon and get some vids up
