has anyone used a s14 or s15 t28 on their rb20 or rb25? i read on zilvia someone took the t2 turbine housing off their s15 t28 and swapped it with the rb25 t3 housing so they can use the s15 t28 to boost more than 14psi. anyone try this?

the late 20 and all 25 turbos are bb center sections...but are not t3 size, some one speculated they were t2 centers with adaptors to bring them out to t3.worth a go i suppose but make sure that it has the correct wheel clearances.

yes rb25 turbo and s15 turbo. was thinking of swapping the turbine housing from the rb25 to the s15 turbo to use the s15 turbo on the rb25 (boost more than 12psi)

I pulled an RB25 turbo apart once, it's gay in there; half ball bearing on the compressor side. Do yourself a favor and sell them both, someone will buy the, and buy a new turbine you can just bolt on.

my teachers always said better to use more commas than not enough.

Go for it and let us know how it turns out.
