Are you still running EFI? If so, what computer are you running? Stock?

Stock ports?

Any ideas on power output?

My dad and I were kicking around the idea of an N/A 20B FB, but, personally, I would love to throw a couple of carbs on it. No wiring to deal with. Heh.

Actually it is great on fuel, much better than my 13B bridgeports over the years

Can get as good as 500 km's to a tank

Yes efi, Microtech LTX12

Extend Port

It has made 230 at the wheels, thats with a stock cat, not a high flow

I wouldn't bother with the carbs, would cost around the same by the time you get a decent manifold made etc

And the efi will be much more fuel efficient

If you have the $ though, go for it, awesome conversion
