Is their any way you can convert from the twin scroll to the what the 89-91 have?
For added horsepower
Cause I heard that the twin scroll isn't as good as what the 89-91 have..
Would you need a different exhaust manifold or something?

 

yeah you just cut the twin scroll flap off then fill the hole with an Oxy/Act welder.

on the exhaust manifold. you want that shut or open?

 

'89 Turbo II's kick ***

Although I am sure the '86-88 models do too

 

you dont want the flapper. cut it off. but when its at idle it should be closed then after it gets to 0 manifold pressure then it opens up.

Will you have the day off ??

 

i'm on nights now, i was wondering because i wired mine open. it stays open all the time. the one that is in the exhuast manifold
