what do i need

[ta17]

i am looking at lt1's and ls1's being in highschool the lt1 is looking better but my question is what will it take to get 400 wheel hp out of an lt1

[93lt1vette]

couple of options
supercharger (paxton vortec ect.) $5000
383 stroker new heads and cam $3500 (provided you do the work yourself)
long duration high lift cam, new heads, forged rods, and re tuned to 8000 RMP
$High
For 400 at the wheels the easyest is supercharging unless you have a TA or Camaro then check out STS rear mounted turbo sys however there is no kit for a lt1 vette
LS1 parts historicaly cost more but LS1 is a stronger engine initaly

Spray it, a 200 should do it. But you'll blow it up without other modifications first.

spray 150 shot of nx and you will be ok as long as you tell the tech man you need help he will give all info needed i think spray is the only way you have to have a hell of alot more money then i have to buy turbos and all that when a kit is chep and if you know what you are doing easy to use but i would get help from some one if you have never ran it

If you do spray, make sure to get the proper safety equipment, like a window switch and a fuel safety switch.
