Is there anything wrong with rebuilding an engine that doesn't desparately
need it? Any negatives? I was thinking that with the running engine, maybe I
could add a hotter cam and maybe a couple of other things (headers, exhaust)
to boost performance without going the whole stroker route right now (all my
money is currently tied up in an extensive house remodel - so long, car paint
fund). Any other ideas on performance mods I can make that aren't too
extensive and expensive to take car of while I'm at it? What kind of HP growth
can I
expect from any of these?
Rebuilding one that is still intact has benefits. Chances are the head is
straight saving that expense. You don't have to deal with spun bearings, gouged
cylinders, broken timing chains, burnt valves, and such things. It should be
more learning about rebuilding the engine and less in disaster recovery. The
less time you spend on fixing broke things the more you spend on fast things.
The r16/u20 bottom end is good for 200hp if put together properly. Cylinder
head porting and valve size are a big bottleneck on the r16. A cam, valve
and port work should be the best bang for the buck. There is some science to
port and valve sizing that is a bit more than I plan to cover here.
