ok, let me take this a step further. Is there a difference between T2 and FD housings?
I would go with an fd motor. A lot easier to located the irons if you blow the moto

The FD rotor housings have a different kind of final coating on the steel liner but I'm not sure what it is. It's supposedly superior to the older stuff and is more "self-lubricating".
The Cosmo rotor housings have a different casting on the exhaust port -> DO NOT USE THEM. The port opening timing runs its way down like a ramp instead of being flat at 90 degrees. Even with T2 exhaust sleeves in them, the bottom of the sleeve interrupts the flow of exhaust and sticks out. I won't ever use them again.

Can you elaborate a little more on this? What do you mean more like a ramp vs 90 deg? Is there a picture somewhere I can see? Maybe a side by side pic of a FD and Cosmo housing. Would it be possible to cut the T2 sleeve in the area where it interrupts flow?

Fd housings had a graphite coating from the factory, earlier motors had a fluorocarbon polymer on the housings. This coating is to reduce wear from initial startup and possibly a little into break in, any housings you see that arnt new will have no coating remaining anyway.

In the 20B the inlets are hooge & power was contained to the supposed 206kW the same way, with masked exhaust ports & a insanely restrictive exhaust manifold & turbos.
A 'gun' 13B build would be FD housings with Cosmo plates and a good terb, but that said I have seen an unopened import Cosmo 13B with a big single make 402 at the wheels.This would be most pleasant.
A 20B done this way, however, would verily be The Finger Of God, coming soon to an Rx5 nowhere near you!
