[Vwdiesel] 1990 Turbo diesel Fox 2 dr Wagon

[Brian and Ruth Decker]

HI Nick;
I didn't have an 1.9 AAZ head ( rare and expensive?) for more air flow. My
turned down pistons do lower compression. It is apparently the larger
prechambers that cause the compression lowering in the Frankenmotor. I'm not
sure if I have a good 1.6 N/A head that I could port the hell out of to get
some more flow. My turbo Fox is defiantly a low budget affair. I'm pretty
sure I haven't got 1000 bucks in the whole project. After taking out about
half the depth of the swirl pockets in the pistons it has surely changed
something. This motor wants lot's of advance on the pump timing. We have it
set at 1.30 now. It is running good but I can't get the post turbo EGT to go
more than about 1100. I will dial up a little more fuel and see what that
does. I think a ported head and perhaps some water/methanol injection
coupled with a turbo with more boost will give me some more ponies. The
engine is strong now but another 20 or 30 horses wouldn't be a bad thing.

When I first read this the first thing I thought of was Hagards Hillbilly
tuning. That would have been my first try since it is a frankenmotor so to
speak.
