	From what I am getting from the 20 or so places I've called....The ten 
times I've bugged Semple and Huw, and from what I've read online...The 
bottom end of an JT/NF/NG engine is pretty much bulletproof til 300k, so 
the lower end doesn't much have to be touched, except for throwing new 
rings in the pistons and taking a look at the cylinder walls to check for 
wear and tear. The head is good for just a port & polish, valve guides and 
seals, lifters and that's about it...Should come under $1000. The real cost 
for me is going to be doing the timing belt, water pump, seals, 
injectors....While I'm at it, I'll be replacing all of my transmission 
linkages, throwing the blaufernugen short shift kit in, shortening my shift 
rod thingy...

Sounds like a fun project.  What kind of a HP gain are you going to get out
of all of this?  As far as wiring issues I think some people have used the

I figure since the engine is good for 130, and all of my little playing 
around may snag  me 10-15%, so I'll probably end up with 145?

I heard. Well, I should be significantly ahead on this game because I know 
exactly what Huw likes to eat for chinese food (and I'm keeping it a trade 
secret) and Nate's just insane for liking to help people for no charge...
