Tuesday, August 12, 2008 12:20 AM
Just wondering what turbo came stock on the 2.0L Turbo Sunbirds? and does anyone have any specs on the turbo itself?

Not really, i'm trying to figure out if they are a T25 or a T28 turbo and what the waste gate was set to factory. I'm doing alittle bit of a 'in your face low budget build' on a 300,000km stock 3.1L to kick a certain SRT4's ass around here (i know i know, there will be alot of people hating on me saying it cannot be done) But i'm a mad man on a mission like i have been in the past and the present to prove money isnt everything

It was a T25 with .48/.48 A/R and the computer regulated the wastegate to 8 or 9 psi. A teeny tiny turbo.

I knew it was small. now this sucks, i've got one turbo from a 80's 300ZX, and one from an 88sunbird 2.0 turbo... they dont match up.. Anyone want to buy a couple good turbos? I think this project is heading in the direction of one large T3 frame or one small t4 frame Ebay turbo

I'm not calling this the 'Grenade' project for the @!#$ of it

I dont think the turbo was computer regulated. There are no electrical connectors to the turbo, just a manifold vacuum line. if you just plug the line and throw a blow off valve on it that would be the easiest way to regulate the turbo boost setting.

follow the vacuum line up from the wastegate, behind the valve cover there's a electronic regulator. how is a blow off valve going to regulate boost setting?

sorry. meant manual boost controller. match it up with external wastegate if you have the means to do it.

Sunbird turbo uses ecm controlled bleed valve on wastegate signal line.
