Does anyone know the wheel trim sizes for my turbo? it's a Garrett T3/TO4E off a 87 or 88 Grand national. The turbine hosuing was modded to accomodate a standard 4 bolt T3 flange.

Exhaust A/R is .63
Compressor A/R is .60

The compressor outlet says M10

I was told it maybe 57 exhaust trim with 60 compressor trim?

here are pics

looks like a T3 60 trim the turbine side would be a stage I wheel i think

 

Thanks! Any other ideas?

Also, what motor would this more suit do you think.

 

nevermind

 

Compressor wheel is from the TO4B (not E) family and is an "M" trim with a 2.75" exducer. Turbine wheel is a standard T3, sometimes referred to as a Stage 1 or -72. Check out some of the GN forums for greater details and hp potential, I'm sure those guys know it all...
