That's what I said re-read my post. I said

"then I think over the 13B-REW would definately be the 13B-RE Comso engine. It has the LARGEST ports on any rotary ever produced by Mazda. "

meaning that the RE would be above the REW due to it's larger ports. And yes the manifold it a piece of artwork isn't it?

 

20b is a sick swap
13b t.t would be nice
if ya gotta n/a then 13bt

I wish think bout the v8 swap myself, and quickly got shut out! O well right...v8 will give you a good instant drop in power, but rotarys are god! I would go with a 13B-REW if you wanna go big juice on a tiwn rotor. The 13BT is good for aboout 400hp or so... The BREW is also a wiring *****! She loves the wires! So I don't like her...that is why I am ordering a nice HALTEK and a single turbo. If you end up with a 13bt go with an 88 motor, you can remove emisions with little trouble, you can run more boost on stock internals, a lot of advantages over the 91 13bt...

 

there was a guy who had a snowmobile with a jet engine.....he was running 3`s (1/4 mile that is)......get one of them and literally smoke the competition

 

I got to go with Pearlwing on this one. A nice used GE turbine would do wonders for your power to weight ratio!
