Forget the 84, if you do the swap, go for the 86- early 89, get the harness
and the computer.... Yes they are bulletproof, and chances are you fine, but
some shopping should get you the later year motor for under 1kUSD....
Doesn't sound like you are comfortable with what you saw, trust your
instincts.... Compression numbers are less key than variance..... The 84 is
a 7.0 compression motor found in the Ur-q/5kt, the 86-89 1/2 are 7.8
motors....... You are undertaking a mamouth project here, don't get suckered
in just cuz you found the motor, they are waaaaay too common..... Good luck,
keep us posted, sure like the idea tho.....
