I am Currently Run a Factory turbo in my 88 Sunbird 2.0L Turbo? I Believe it a Garret t-2.5 or something to that Effect. I am looking to Upgrade the Turbo to a Garret T-3/4 I know the will need to mod. But My Wastegate for my factor Turbo is Shot. So I am Wonder about Wastegate should I be looking at I have seen a Few different selections? There is a 30mm,35mm, 38mm, and some other ones Higher. But Looks like alot of extra mod's to get these other ones in working but there is a 46mm and 50mm? So I am wonder What the makes these different? If I understand this right the 30mm is the distance this moves the turbo control arm? Am I right on this?

I beleive the 30mm is the size of the port size.. I would post this on v6z24.com to get more exposure and replies..

can u even run an external wastegate on the 2.0 sunbird???

"Hondas are like tampons, every pussy has one!!!"

you could.. would require welding a flange to the manifold and blocking off the internal gate,


watch for flying sparks!!!

You can't just slap an external controller on the stock setup. Outside of that your post makes my brain hurt.
