Hi all I have an 03 qclb just picked up a he351 and what I belive is a gt4202? Or a gt4294 it has a 1.15 ar exhaust housing non gated and a part number of 23528029 any help identifying this turbo would be appreciated thanks

Thank you. I have a 1.15 a/r housing should make a nice set of tight twins with my 351.

Read that wrong. Dang 65.5mm compressor really small. Looks like I lost that gamble.

Well they would spool super fast, hell my search results could be wrong too, I'd just measure it and you'll know for sure.

I'll have to throw some calipers on it tomorrow. My goal is about 600hp but overall I just want a super Street able truck so if it's around the 68mm or larger compressor wheel it should work OK for my application. Mabey swap housings and wheels with a gt45?

So I got some calipers on it mine are terrible but measurements are as follows
Compressor wheel
In. 67.8mm ex. 94mm
Turbine
In 80mm ex. 75mm

Turbine is 80/85

And here I was thinking I was the only one that still owned veneer calipers!

You'd just have to think about the throttle to spool it.

I was thinking with the non gated tight housing it would spool fairly quick but this is my first twin build. If it has the same frame as a gt42 I'll go ahead and use it as it would be easy to swap out for a larger turbo later.
My calipers are beat I found them in the garage when I bought the house from my wife's 92 yr old grand mother but hey they work.
