I need some advice on what engine I should build. It would be used in a lightweight RS or RSR replica, about 90% street, 10% track. Requirements lean much more toward street.

My budget is $15k for the engine, and I am starting with a bone stock 1986 3.2 with 115,000 original miles. Never been opened up, but aside from valve guides and rings, let's assume all the usual items are in spec and reusable/regrindable.

I will do all the disassembly/reassembly myself, but I have never done an engine rebuild of any kind before. I've got Wayne's book and I'm confident I have the necessary skills and patience to do it properly by following the book. If you think I'm not being realistic, please tell me so. All the machine work, including head work and any mods, would be hired out.

Ideally, I'd like to end up with a 2.8 of some flavor and configuration, given my budget constraints. I'd like the engine to last at least 75k before needing another rebuild. And, it must be able to pass a fairly strict emissions test, with cat required (but swappable with a bypass for track days).

If the 3.2 isn't the best place to start for an engine like this, I will gladly sell mine and buy whatever case/crank/rods/etc. are necessary. I realize that this kind of work might not be advised for a neophyte.

So, given what I have to start with, the intended use, and my $15k budget, what's your opinion on what I should build?

Follow up question (quick answer): How far outside my budget is a twin-plug MFI 2.8 with ITBs?
