side seal ?
 

Ok, I'm going to be rebuilding a 90 n/a engine. I'm looking in the parts manual and there are different side seals for turbos and n/a's.. Whats the dif? rotors different or something? This car *might* be getting a turbo put on in the future (vert) so should I go with the turbo seals or stick with na ones?

ok, turns out there are alot of parts that are different... like apex seals, side seals etc....

Whats the diff?

The internals of the TII engine are lower compression rotors b/c of forced induction. The N/A's had higher compression (larger) rotors. It'd be safest to go with the parts built for the car AND year (86-88 is different from the 89-91, 89-91 had lightwieght rotors and more durrable parts (durable in the fact that its reline is higher).

the difference is in the coating. use 93+ cornel seal springs they are a lot better.
