Default B18A1 Build Up

Okay so now that I have decided on the 92-93 B18A1 motor I need some more help. What all do I need to do to the block to reach my goal of 400 fwhp? I know I'll have to sleeve it but I want to stay at the stock bore. Can I bore it to say .030 and then resleve it to stock bore? What else willI need to do to hold that kind of cylinder pressures?

Somebody correct me if I'm wrong, but I don't think you need to sleeve for 400hp. I believed it to be necessary when upwards of 550hp.

Still better to be safe than sorry. But if that's true then I don't have to do anything else correct?

I'm planning on doing all that but I need to build the block first to be able to hold that kind of cylinder pressure.

I understand you feel the need to reinforce your cylinder walls, but do a little more research. You may be able to save urself the extra 6-800 bux on something more necessary. Not tryna come off as an *ss, just would hate for u to waste ur time + $. I know a guy locally who's running ~440whp with just the list powermidget gave + a good tune. Here are a bunch of examples of big power out here in PA from a local shop called Evans Tuning: http://forums.evans-tuning.com/index...c5af56d4347c9e

I'm sure those guys can give u another perspective rather than just mine. Hope this helps.

Not tryin to be **** here but money really isn't a concern on this build. Would it not be better safe than sorry? I mean it's not going to HURT the block being sleeved, I just want other options on top of sleeving the block to fortify it. I mean can I do anything else to make it stronger?

In that case I'd say sleeving is ur best bet. Forged rods, new piston rings, and maybe a double or triple-layer headgasket. Add that to powermidget's list and u should be set.

FI cams blow. ITR/CTR cams ftw.

I'm no where close to buying cams yet...bottom end first then top end. But when I do more than likly they will be Comp Cams.
