REDTURBOSS

I am finally installing the kit after 8 months of waiting, I am in the process of installing the heads and cam, and will then move on to turbo....I think this kit might be to much for me in terms of power I might go D1sc supercharger if I can get a deal before I am done with the H/C install will see...some pics for u guys.....

Are 42lb injectors enough for H/C + 9 psi?

Depends on the turbo kit and supporting hardware. I maxed out my 42 # injectors right away with my turbo setup and had to upgrade to 60 #'ers.

60's would be much better to start off with. Less hassle in the long run.

Wait, is it a Pham kit of Groundzero kit? I'm so confused with these kits popping out of the woodwork ! I'm glad I can build a turbo system myself.

Unless you have forged rods and pistons, I wouldn't add forced induction on top of having added heads and a cam. The only way to keep if alive is to keep the boost down, along with a good tune. Bob

hmm, i know someone that had heads, cam turbo kit and a good tune that ran pretty well, hit nines on the stock bottom end. He also had 42lb injectors.

im getting somewhat scared know, what would be the max boost I could run with the lq9 heads and the cam on my sig. I always thought 9lbs was okay on the stock bottom end.

There's always someone who gets by but as a general rule I don't advise it. That would be like saying, since I know one person got by, everyone else won't have any problems. Heck, my own 120,000+ Z28 stock internals survived quite a while at 15 lbs of boost. Bob

I'd shoot for 6lbs of boost, unless you can afford to pay out for a forged bottom end in the event you need to. Bob

Do it by HP ,not boost level. I'd say 550-600rwhp with a safe(rich-low timing) Tune

wow thats a rather large turbo cam.You didnt mention if the heads were stock or ported.Id also shoot for 550rwhp until you save the cash to get a forged bottom end.Thats still plenty for the street and a relatively stock car.Id also recommend selling the 42# injectors before you use them so theyre still new and get 60#ers.

How many hard runs?

He's talking about my old setup. oringed 5.7 ported heads, cam, stock head bolts. On a 100% stock bottom end. 12psi max boost. Ran it all season many many times. Plus street driving. When we tore it down it was in perfect condition. Went a best of 9.85 @ 138 mph. @ 3450 race weight. I think it is still the fastest/quickest FI stock bottom.
Don't try this at home.

You can try it, but not unless you know what your doing.......
I don't so........

But I've done 10,000mi on my stock bottom end at 8lbs, It has lq9 st. 2 heads, a mild boost cam and a very good fuel system with 50lb inj's.
Seems safe for now, I'm in the 575rwhp range.

And thanks TwnTrboCE, you the one who got me started with my first TT kit. Been loving life ever since! Then I sold it to cablebandit and traded up to another with 37's.

Exactly. I decided to run a little more boost (10.5 lbs) and a low AFR with little timing. 600 rwhp and the stock bottom end is running great (car has LPE GT2-3 cam and worked over LS1 heads). I could make the same power with less boost, but the tune wouldn't be as safe. In short - don't get hung up on the amount of boost. Focus on the hp level.
