John, first off, let me tell you that i am probably
close to the last person you want telling you how to
build a motor. I don't know jack about it. Well, my
fiance just pointed out her dad would do a worse job
(which is true), but the point it i am just figuring
things out as i go along (i hope).
Secondly, this motor is still very much in progress.
It is in the clean-up and maching and parts procuring
stage. So unfortunately, i can't get you an HP
numbers. However, when i get it put together and
broken in, i'll probably pick up one of those g-tech
pro thingies and get some HP numbers.
Heck, i don't even know if this motor will last more
than 40 miles (i hope so... honestly, i'll be quite
happy if i get 80k out of it).
To answer what questions i can, though:
heads - i don't have this finalized (heck, i just got
the go ahead this morning!)
crank - dpr is doing the work, but you typically have
to go through someone (like boston bob) to get work
done. And the final stroke is 82mm (stock is 76 for
the 2.1)
pistons - about 0.140" will be shaved off the top to
maintain correct CR. AirCooled.net has some
uber-fancy pistons with the correct pin location for a
stroker crank available, but they are $$$$. I'm
trying to keep stock compression ratio.
rods - stock but 1.9 hardware. keep those rods strong
for the increased stroke.
source of pistons, cylinders and rings - got them at
Bruce Tassi's in colma, but if you look around there
are a few places selling these things. Honestly, i am
a little suspect of the quality of these taiwanese
pistons and cylinders over a pair of german ones, but
please see my first paragraph regarding the caliber of
my critique.
I've just spent the last couple months looking in the
archives, talking to a couple people, and searching
the internet for a variety of opinions and "facts"
trying to find the ones that make the most sense to
me. The only way i feel kind of OK about this is that
i am not trying to skimp on parts...
Ok, i'll leave it at that since i've already gone on
for far too long about something i don't know a whole
lot about :-)
