Hey, I'm gonna soupe up my 5mge this summer, this is what I'm thinking... I wanna have the engine rebuilt, the pistons bored out, then make the pistons high compression and y'know, just the basics to make that all work, then I wanna stick on a turbo and shoot for about 20psi of boost. I think I can do this all for about $1500 and I was wondering if any of you have suggestions on what I could do with it, I'm shooting for about 400bhp with the turbo putting in 20psi, but if I can't hit 20psi do you guys know any way I could hit 400 without using as much boost from the turbo? Also, any good exhaust and headers and crap like that I should check out for that kinda power?

youre pesimistic, the pistons in a 5m suck, they gotta be replaced. I think I could hit 20psi with the right parts and equip... maybe 1500 is a little low, but I bet it shouldnt be too much more.

hmm yeah, maybe a 7mgte is a good idea, yeah, I haven't done much reading I'm still getting into the thoughts of what to do (that's why I've done nothing yet). I have about 3-4k to spend.

So I take it the 8.5 compression ratio is good to keep.

I don't have the mechanical skills for doing an engine swap on my own, so it would seem a lot more cost efficent to just keep the 5m.

20psi... yeah, thats wishful, lol... think I could get to 15 for about 4k? The body is in good shape and the transmission is fairly new (about 30k miles)

I dunno, I guess I could do a swap, I've just never tried. We actually did make a time bomb with my friends prelude, so that's why I think I can do that again. I'm no car idiot, I know how to do it, it's just that I've never done it so it scares the hell outta me, lol.

Okay, I just got off the phone with a mechanic... he was sayin that I could get a safe 350bhp 5mge for around 2500, is he talking crap or what? Cuz from what you all say it sounds like it but I dunno, he knows more about cars than I do.
