Right now my 12 valve is pushin around 280 hp and i dont know how much torque. I wanted to see if anyone could give me advice on what i should do to it to get it pushin around 450 hp. I have fuel plate, intake, and exhaust done. Thats it. I haven't put it on a dyno so im not 100% accurate with the horsepower right now. would i need a bigger turbo? faster lift pump? injectors? any advice would be appreciated.

 

transmission...injectors......turbo.....dv's....4kgsk...60lb valve springs...

 

so instead of a 3k governor spring kit get a 4k? Would that be too hard on the engine? and what are the valve springs? what do they do? sorry for all the questions

 

if u already have a 3k you dont need to switch ....but 4k fuels harder. when u install a 4k gsk you SHOULD install 60lb valve springs to keep from floating a valve which is easy to do after 3200 rpmish.

 

alright, so i should get 60lb valves springs anyway for my 3k. how big of a turbo?

 

you don't need them with ur 3k. because you wont be turning over 3200 rpm. i recommend a 62/65/14.... would b plenty for 450 hp and some room to grow.

 

alright sounds good. Thanks for the help

 

thats what were all here for.... get help and give help
