Ls1 And Fi.. Read!! Need Info!! Okay so last night me and my Dad are chillen out talking about the car in the garage, and we were deciding on what to do next. Him and I both love the FI route and really want to do it without starting over on the car,but it became an argument. So here were the opinions from both and ya'll can tell me what needs to be done.
02 Camaro SS -A4, Full bolt ons, Mti stage 2E ,232/238 .595/605 on 112, a 3600 stall, and 3.73 gears.
Dads Opinion- We would have to start the whole car over, and put it back to stock. Also that the pistons in the LS1 cant handle a turbo and needs different pistons. Also that my heads and cam wont work with FI( I agree with that, OR COULD I USE MY HEADS SOMEWAY??).
My Opinion-That I could sell my heads for 6.0 heads, and change out my cam and sell it for a different cam. Then my compression would be around 9.5.1 and I could go turbo and run about 5 psi until the motor was forged, or forge it and do the turbo all at once. My dad says we have no choice but to go nitrous.I beg the differ, but I went a wrong route with this car when I was just a damn newbie lol.
Please help me out,Info is greatly appericiated
Thanks Chase

Thanks Chase The heads could probably be used. The cam changed, gears changed, upgrade the tranny or buy it when it breaks which it will (assuming it's still stock). New rear. The shortblock can stay stock but will limit you, new fuel injectors and maybe pump depending on HP level. New verter if you change tranny (th400). Tuning is a must as well. Different turbos perform differently at lower boost so you may want to go bigger later once you get the forged block or not but something to think about. Don't forget to upgrade your suspension cause you will need to for the best performance from the new set up.
Good luck to you!
Good luck to you!

Well this is a DD for now, so and even whe its not I want a street fighter, and probably going with a built 4LE60 and a 12 bolt soon. Full suspension is getting done on Thursday. I know the cam as to go, but as far as the gears and stall, I cant use those???
The stall is fine but if you go with a th400 a new verter would be needed. Instead of spending the money on a built 4l60E you could use it for a th400. Either way the gears will need to change (do it when you get a rear). Pistons would help lower compression.
What turbo would you want to go with? HP and TQ numbers?

Well I am really leaning towards the sts kit, and I want to get to about 550rwhp and more room to grow if I choose to run more boost. I will probably want to upgrade the turbo later but I would love to go with the FI route
So the best thing to do right now is forge the motor, rip the cam, and get the sts all at one time. So say I was to forge the motor with out pulling the cam and waiting awhile for the cam and turbo kit to go in?? Would it f**k up my motor??

If all you want is 550rwhp, just change the cam, upgrade the fuel system, and dig a hole to throw your 10bolt rear in before installing the turbo. Seriously, the rest of the block and heads should be fine, although you will probably want to run meth injection or a good intercooler to get that power on pump gas at stock compression ratio. If you have the dollars to throw at it and may want more power later, a forged shortblock and 6.0 heads are always nice to have, but not always necessary.

So with my setup, what if I was to install a ati procharger on my setup???could I keep the cam I have and do something with my heads to lower the compression. Only 18 years old here lol so the budget is limited.
The cam has to go. Not enough LSA to build any boost (too much valve overlap). I ran 4.10s with my rebuilt 4L60E & they were too much. 3.40s were not enough. (50 more hp & 100 more lbs of tq = identical ETs) I run a 3200 stall & it flashes to 3750, so that stall might be too high. I say try it & find out. And 6L heads will lower your CR so you could run more boost. But if you keep it low they should be ok....for now.
Or you could just spray it. Your dad is right about your setup liking juice.

You could install an ATI ProCharger right on top of your current combination. What is your compression ratio at right now? An ATI ProCharger will work with 10.5/1 at 8 psi with 93 octane fuel. With the stock bottom end, and your head/cam package, I would limit boost to 7 psi until you forge the bottom end. With a good fat tune, you should be okay but you'll be pushing the limits of the stock bottom end. Bob

I'd go off what Bob says...he knows his stuff. I'm looking to do the same route but don't want to worry down the road and will defintely be doing the D1SC thing once I get back to the states. I want reliability as my car will be a dd and from the sounds of things procharger is the way to go. And what you already have done to your car sounds this would be the easiest thing for you as well. Good luck!

I'd go with Bob...My buddy is going with FI route though & he has a fresh motor (24K) so i highly recommended him to get a Procharger D1-SC for his stock bottom end & running 8psi with 93octane all day long

). I will probably end up only running 5 lbs of boost for now. Also I would like to know, this might be a dumb, but if I go buy the procharger kit is it worth the money?? I am 18 and the budget is tight lol, and what do I need to get this whole setup ready to go into the car?? 
If your really worried about the budget now (which is understandable) you may want to keep the head and cam and go N2O. FI isn't something to get into if you are on a tight budget. You will almost always go over budget and it will take time to get it all right. I say buy a N2O kit, window switch, fpss, and spray the sucker. Then save for a FI setup. Do some research on whats out there and other peoples set ups. However it is your money so do what makes you happy and good luck with the set up!
