Yeah.. umm... that customer was me. And thanks for
the engine life upgrade, but it really only lasted 6k,
not 8. Main reason for the detonation was that the
2325 (82 stroke, 95 bore) was my first engine build (i
have a bad habit of not starting simply). The high
compression ratio was from me running out of time and
trusting people too much and not checking things for
myself.
I had Bob repair my motor, and through talking with
him, doing it "right" is waaaay more difficult than
doing it my way (i.e. the wrong way). While it
lasted, I did have the same driving experience as the
previous poster - felt nice and "modern", but not for
as long as i would have liked. Learning experience,
though. Now, i am breaking in my brand new (drove it
home today) slightly smaller engine (82 stroke, 94
bore). Hopefully reliabilty will be waaaaay up, and
still be as much fun to drive.
Now i won't say a Hi-Po WBX is a bad idea (a novice
got one to work for a little while, anyway), but i
think there is still a bit of long-term reliabilty
validation people need to figure out. For example,
I'm also not sure how keen i am on the 95mm chinese
pistons to bump up the displacement. I'd stick with
German and lose 1mm.
Now, if any of you big displacement WBX guys want to
share tuning tips, i am all ears, as that is my
current challenge - tricking the digijet 1.9FI into
thinking it is a 2.3. Until i finish my megasquirt
FI, that is...
Glad to hear yours is going well, and thanks to Bob
for fixing mine!
