View Full Version : .82 housing with stage I?

Would an .82 A/R T3 turbine housing be a waste of time using a stock (stg I) turbine wheel?

Reason I ask is because I have a Garrett T3 turbocharger from a Merkur XR4Ti that I would like to use on a project of mine (the 2.5L TIII). Specs are .60 A/R w/60 trim compressor and a stage I turbine wheel. It came with a .48 turbine housing that was cracked so I bought a .63 housing for it. I'm wondering if an .82 would be even better considering the motor it's about to go on. Plus turbo changes are easy on a TIII so I could experiment down the road. Thoughts?

I am guessing but I think it would be very laggy, but interested to see what the pundits say.

Same here. I rarely hear of anybody going bigger than .63, and going with a higher flowing turbine wheel is much more common but then again most TDs are stuck with the Chrysler flange setup whereas the TIII motor can use a standard T3/Ford flange setup so .82 is an option. I do know that Cliff went with an .82 housing on his 2.5L TIII wagon because of 'uncontrollable driveability issues'. But he had a much larger compressor (57 trim T04E?).

It sounds like an interesting experiment. You have the .63 to try for now. If that spools pretty fast it might be worth trying but I wouldn't even know if they are available.

That's just it, I don't know if they even exist (.82/stg I). So far I haven't found one. I know ATP carries the standard T3/Ford housing in .82, but according to their catalog they are all for GT series turbine wheels. I emailed them to see if it stage I is available...but that would be an expensive experiment. It would be nice to find a used one from some kind of OEM application.

Since the usual reason not to use it...doesn't exist for you, people aren't going to do so well arguing against its use (with their "vast" knowledge of something never tried :P )

You are just calling the wrong people. ATP doesnt built turbos. They resell stuff for more then the manufacturers cost. Try calling Precision. They use the same housing for each wheel, they just cut more out of the housing to fit the larger wheels.

I dont think you are going to find a .82 housing on a factory application.
