you can def reach 300hp on ur ls, but def wont last as long as u want it too. i gota 94 ls stock, with a t3 turbo running 12psi daily, and its real quick but nowhere to 300hp, mayb like 230 or something, but even i dont think my motor will last night. good luch though

When you guys say stock, do you mean 300whp with a completely stock block, no lowering compression?

turboDA6

that would mean stock, in order to lower compression you would need lower compression pistons. 300hp on completly stock motor is possible, ask xenocron

I have seen 292 hp on a stock Ls but it had arp rod bolts , t3/t4 57/60 trim some ---- with 12 psi
SFP manifold 3 in exhaust no cat 650 injectors it was tuned on uberdata

i ahve seen more than a couple push over 300 even 332 and still have not heard of it blowing,,theres 3 cars here that all are pushing 290-330hp on stock ls motors and only one lhas let go that i know of

if you get a real good tune on that bitch, and don't constantly beat the **** out of it, it might last ya awhile. i'd suggest running a lower boost setting daily, then just turning it up on the weekends or whenever your going to race

getting 300whp on a stock block isnt the problem, its difficult but doable. its keeping your engine running after your ringlands break. i would seriously look into forged pistons if you REALLY want to run this type of power level for ANY amount of time.

dammm i cant even get a stock motor to last a year na. it seems my turbo motors last longer than the na ones. the thing u will probubly change first is ur pistons and when u have to do that through some forged pistons in with some eagle rods and than it should last a year.

i have 2 friends that has a b16 with 330whp and a ls 301whp both stock and its last them over a year, they tuned the same time and i personally think its all in the tuning, even tho they are running that much i wouldnt do it like hotrex said thats pushing it but hey its your motor and your money. YOU GOTTA PAY TO PLAY.

idiot-stick

I've got a friend with a ~300whp stock B18b whose been running for ~2yrs and beating the **** out of it on a daily basis.
