I have a B16a2 on the way and i was wondering what it was going to take for me to be able to put about 25psi in to it without blowing something this is my first project car and im trying to go big or go home

 

for the most reliable turbo'd engine punch sleeve low compression internals and such. but if you want to go big do an ls vtec. then build the hell out of the ls bottom end. then you could lay down about 400/450 hp on 35 psi and race fuel. daily driving at about 20 psi and pump gas. take it to a local turbo shop (The Shop in kingsport, TN, if your close it's the best) and have them build it.



this should be posted in nitrous/turbos/supers not swaps.

 

I think what shane meant to say is that the B16a2 has thinner cylinder walls and likes to blow up when running higher boost, so you would have to put new sleeves in the engine and then replace all the internals like rods and pistons to handle that kind of boost. The stock crank is good for a lot of HP but I'm not sure how much.

I think he also recommended that you use the bottom end from a B18b1 and the top end from your B16a2 or from a B18c3 to give the engine vtec. The b18b1 block is a bit sturdier.

I'm not sure where he got all those numbers on PSI and HP.


OP, when doing your first build, I can't stress just how important it is to set goals and divide your project into stages. You have to understand that you're making an engine 2x or more powerful than it was designed to be. You'll have to do more than just build the engine to make the car safely handle the extra power. You'll need to upgrade the brakes and suspension for sure. That adds to the cost of the project.

 

tehe. my bad. that's what the ls-vtec is pushin down at Dashboard Audio. thanks for clearing that up Mr.hobo.
