Need some input on TT set up Hey guys.. Im looking to build my first TT set up.. I have always been true to my NA blocks but recently I have had evil thoughts. Im very unfamiliar with boosted set ups so laugh at me if you feel the need but also correct me if I'm steering in the wrong direction. Im looking to do a TT set up on a 98 LS1 block (camaro). I want to run 14-17 Psi on pump fuel. I think I put a decent package together to do it but I need some input.
AFR 230CC 65cc chamber
285/281 621/617 115lsa cam
-4cc dished piston which should put me around 10.4:1
Already have Ported intake.. right now its matched to my ported stock heads.. also ported for current 80mm throttle body
42lb injectors
All valvetrain will be new and upgraded as well
Also already have a full forged rotating assembly
My questions
Enough/Not enough on the injectors @ 17lbs?
Is this set up pump gas possible?
ill be running twin T4 .62ar turbos

For 14-17 lbs of boost I would at least add meth with that kind of compression. Maybe look into running e85 if it's available also.
The injectors are too small for what you are looking to run. 80 lbs. injectors would work for pump gas. Not sure how much is needed for e85 but I'm sure someone else with experience in e85 will chime in.

How much power do you want to make?
Those injectors are way undersized.
Making big power (850rwhp+) and driving it on the street eventually will make the cylinders out of round and begin to lose ring seal on an LS1. Meaning after a few thousand miles.
You can lightly hone it and re-ring for the same thing to happen a few thousand miles again later.
If you have the money spend the extra coin and start with an LS2 block. The bigger bore also allows you to run larger valves since they will be less shrouded.
A stock crank is good to 1000rwhp. If your goals are more than that.... you should pretty much save your money for a better block as the 4 bolts heads will have a tough time sealing the head gaskets.
Rebuild the stock rocker arms with the Comp Cams trunion rebuild kit if the heads you choose can run them. You don't need new ones. Just rebuild them.

I'm looking to get somewhere around 750rwhp. I don't really have money for a whole new LS2 set up. If I bought the block I couldn't afford to the the TT set up right now anyways. I was thinking if I get my turbo kit and get it on the LS1 running low boost on what I have now and swapping out the cam I can run that then next winter when I put it away I can sell the block and buy a LS2
