MicroMachinery Posted November 29, 2009 Report Share Posted November 29, 2009 The guys says it's a T3/T4.. something tells me he's tryin' to pull the wool over my eyes.. the tag says part number is 465153.. looked it up and it looks like the number for a T25. I just want to confirm this before I tell him to make tracks. Thanks! Quote Link to comment
sssr20det510 Posted November 29, 2009 Report Share Posted November 29, 2009 t25 will have a smaller flange than t3/t4 Quote Link to comment
NorCalDime Posted November 29, 2009 Report Share Posted November 29, 2009 no pics.... but you can tell by looking at the footprint. 99% sure it is an ebay turbo, so dont pay more than a couple doll hairs for it. unless you have pics to prove otherwise t2 aka t25 28 etc Quote Link to comment
NorCalDime Posted November 29, 2009 Report Share Posted November 29, 2009 coudnt find a t3 measurement but here is a size diff. t2 t3 Quote Link to comment
MicroMachinery Posted November 29, 2009 Author Report Share Posted November 29, 2009 The more I look at it, the more I'm thinkin', WTF? Where the hell am I supposed to bolt up the downpipe to? The outlet on the compressor side looks too small to be a t3/t4. I thought ebay turbos were pretty much no-name.. can they put something like "AiResearch" on the side, as well as a Garrett id tag?

NorCalDime Posted November 29, 2009 Report Share Posted November 29, 2009 we need pics or we are shooting in the dark... Quote Link to comment
DISLEXICDIME Posted November 29, 2009 Report Share Posted November 29, 2009 sounds like a dsm t25 from how you are describing it is there a 5 bolt flange on the hot side Quote Link to comment
hughdogz Posted November 29, 2009 Report Share Posted November 29, 2009 (edited) I think NorCalDime is right. The T3 turbine flange is 4.25" x 3.75". That's most likely a T2 or as you suspect, a Toyota CT-20 or 25 :blink: If it says Garret AirResearch it could even be a TB-20 popular with the Toyota 4x4 turbo upgrades: Even so, a T3 (or T4) can be so different, depending on the A/R (Area to Radius ratio). A T3 can be .48, .63 or .82 A/R. So all T3's can have ~3x the size between a 48 and 82. .48's are good for 4-cylinder engines, .63 for 6-cylinders, it's all about flow (CFM) to match turbo size the engine and target power / RPM. .63 T3 compressors are roughly 4.5" diameter and .63 T4's are ~7"+ dia. Ultimately, it will depend on the inducer and exducer diameters (turbine inlet and outlet diameters) for how much it will flow. Hope this helps...

MicroMachinery Posted November 30, 2009 Author Report Share Posted November 30, 2009 (edited) Here's a pic of the exhaust flange... yeah.. looks like the t2 alright. Edited November 30, 2009 by MicroMachinery Quote Link to comment
Pedro Posted November 30, 2009 Report Share Posted November 30, 2009 The ca18et turbo's from the s12's had a garrett t2 with air research written on them, probably one of those. They are tiny. Quote Link to comment
MicroMachinery Posted December 2, 2009 Author Report Share Posted December 2, 2009 What are you rappin' about? VR? I think you're looking for the vw vortex. Quote Link to comment
