the motors are pretty much the same. You dont neccessarily have to rebuild it, sometimes youll get a good tight motor, but its something to have extra money to do in case it needs it.

You can take a chance. not like vosko, i've been blessed by the jspec god

. My jpec has great compression and I've been racing it for the past 8 months, no leaks no problem. I was just lucky.

RIght vosko? :smirk:

there are 3 ways to do it

1. use the 89 block, with the 87-88 electrics

2. use all of the 89 electrics, the whole car

3. use the 89 stuff in the 87-88 car, and make adaptor harnesses

Number 1 is your best bet if you want it up and running quickly.Who cares about S5 electronics?Thats why they build standalone systems. :smirk:
