Well, I pulled the head off today, the head is in good shape, and the cylinder bores in the engine look great, there's very little wear and very little ridge, the pistions look good and they were all burning simmilar. My teacher asked me about adding performance yesterday, and I told him that I had a Turbo to put on it in the trunk and he wasn't very enthused by the idea, but said, we'll see, today after I got the head off, he was verifying that I wanted to " Zip It Up a bit " and I told him yes, and that I was going to use the Turbo, then he says I would need a new exhaust manifold or mod the existiong 1 ( which I knew ) and that it wouldn't be worth it, I tried to tell him that most of the Turbo 200's that I have seen use a "J" pipe coming off the manifold, but he cut me off saying that the exhaust manifold is very restrictive and that a set of headders would add performance, I have researched the 144-250's and there restricted in the intake due to the log head, and headders just sound cool, as the stock manifolds flow better than the intake anyway, the headders would do nothing, maby 20 or so HP if that. so he's planning on me spending $300 on a set of headders for the engine, because he says he knows I don't want to spend a lot of $$$ on the engine ( I never told him I was going on the cheap ). Tomorrow I'm going to tell him that ither I leave the exhaust alone and I'll hook up the stocker exhaust for now, then add the turbo when I get it home, or he lets me add the J pipe and put the turbo on in school. the whole 'needing' a rebuild was so the engine could saftly be turbocharged, the TBI EFI is just a ' Because I can ' Icing on the cake type thing.
