Ok here is the deal I have a 90 Crx and I dont know what to do... Right now I have a B2 block w/ mini me Y8 head, Mani, Injectors and I also have a good turbo setup I am building up right now just need a few more things.. But I have some money right now to either build up a Si engine that a guy is selling complete w/ everything!! Or Buy a B16 and run that Na until I can afford a turbo or something for that.. My question is what would you do?? If I get the A6 engine from the Si what should I do to build it up to handle 10-12 psi on a low budget... Pistons, rods,crank or whatever??? I Love Dseries alot but I just dont know what do at this moment. Please help and also where to get the parts to build up the SI engine..
