is a garette t25 the same size as the stock wrx turbo?

 

I don't belive so. A T25 is a SMALL turbo. I don't think I would flow enough for even a stock wrx.

Tats.

Also...replied to your PM.

 

thanks for the info.! so what about the flanges on the stock wrx turbo is it the same as the g25 because i was woundering if the wrx turbo would fit on the avo kit?

PM you too!

 

The T25 comes on the avo kit. It's bigger than the stock WRX turbo in different aspects.

Running the stock wrx turbo on a 2.5 is a very bad idea, the turbine is too small increasing backpressure on the engine which will cause more detonation (or so Shiv told me at a test and tune day). IF you have too much backpressure you won't get a good cylinder scavenge during overlap (when intake and exhaust valves are open at the same time). This helps to flush out all the old combustion materials and remove some extra heat. Too much backpressure means you can't get rid of the extra heat and you increase your likelyhood of detonation. The T25 is a better choice. The T28 or 32 would be even better.

My kit has a cheesy rebuilt garrett T3/T4 thrust washer, slow spooling hunk of metal you can get for 300-400 bucks. But it's good enough for high twelves.

 

thanks imperzarsx. did you move?! so the avo kit is a best bet! is there anyone with time slips with the avo kit?(what are they running 1/4 mile)

 

well, if you're looking for 1/4mi times the AVO kit isn't it.
The GT25 isn't big enough for big HP numbers. Only low boost (8-ish) That'll cut ya 13.7-14.0's ish and that's probably optimistic. If you slapped a bigger turbo like the GT32 or GT35 on the AVO kit, then we're talking 12's and broken tranny.
The AVO kit is more of an AutoX kit. Low lag, good throttle response. It runs like a stock WRX profile.
