im always to scared to do stuff to my car.

 

is that the same way you would port a '90 fc?

 

hmm. how much do you port it? is that door supposed to fit snug on it or what? or is it just move freely.

 

I believe the 89 up turbos don't need to be ported since they have two passages stock. I ported my 87 TII and it was no problem. I made the hole the size of the stock disc seal, back cut it alot and made a new disc seal out of an exhaust valve; although I have heard it doesn't matter if it seals well. I still run 7-10lbs boost w/ TID mod, downpipe, midpipe and stock cat back. The TID mod really brought the boost back up after the wastegate port w/ out needing a boost controller.

 

I'll havet to take my turbo off again, but it will be worth itin the long run. I will letyou guys know.

 

The 89+ WG's are better, but you should port the 89+ if you have it off.

A TID mod and a down/mid pipe can lead to hellacious boost creep (11+psi) even with stock catback. That's even on a 88 motor that in theory might be moving a CH less air than a 89+ turbonium motor.

Will, I have a manifold that has been ported. If you want to try it out, you can!
