I still say either the 13B-RE w/ upgraded single, like I'm running.

Or just go LS1.

The RE has larger intake and exhaust ports, which in our case, will help give better torque and low end power.

13B-REW:



And here's the 13B-RE:



About 10mm larger.

Aside from the intake manifold, even the intake and exhaust ports in block itself are larger and shaped differently.

Stock for stock, the REW was rated with slightly higher HP...but running the same setup on this RE motor, as was on the REW before it....I'm SURE it will put it out more power.

My brother got it running yesterday, and says he'll get it tuned this Saturday for me.

I'm telling ya man, the REW is so unreliable to. When it comes to rotaries, they're the worst. The 13BT that comes in the Turbo II's is by far the most solid. I owned an '88 Turbo II with a Series 5 longblock and Series 4 mechanical oil-metering pump. It was ROCK solid, and never gave me issues.

Flippin' REW in my first FD...piled with my lack of knowledge at the time...yeah, it was a nightmare. You throw on a single turbo, Power FC, and all the standard supporting mods...then sure, you're doing fine...but again....why??

I think I've made my point.
