Hey my fellow wankel heads. I was sitting with my friend last night and we were talking about our FB's. He's got a Maria Mode One GTO body kit with 12 inch wide tires in the back and 10's in the front. He also is building a street port turbo 13B engine w/dynamic balance, hybrid turbo, HUGE front mount intercooler, etc. It should put out about 300 before the hybrid turbo is put on, 400? after the to4 compressor/stock second gen exhaust turbine is put on.

Anyhow, I couldn't figure out what I was going to do. First I wanted a 12A turbo, then a 13B turbo, then a 12A bridgeport, then a 13B bridgeport.

But a couple nights ago I had an awesome idea. 12 A turbo with a BIG street port. That's not all. It will employ all sorts of turbo 2 stuff. Since I'm poor and relatively smart, I was thinking about a turbo 2's computer, turbo with a custom intake and exhaust manifold, injectors, intercooler (top mount and just cut and custom mount a hood scoop). To get those injectors to work with a 12A, my friend told me about GSL-SE intermediate housings and how their oil seals are NOT there; rather, they are like 12A's and they are completely smooth. So, they bolt right up and work.

At first, I was wondering about the workability of the turbo 2's computer working on a 12A. Would it work? My friend said that if you do a big enough street port, it should flow as much air as a stock 13B four port. Cool, I thought. So now all I need is the money....

Thoughts? Suggestions? Post em!

P.S. My fender flares came in yesterday. 7" wides in the front and 8" wides in the back!

 

I'd say go for it.... the TII ecu should work, I just don't know how well. It does base its injector timing based on MAF flow, so it should be ok.

 

do a search on moremazda - he's a dude that put a TII turbo on his 12a, and did it all with hardware store parts... done in-expensively, but looks good and runs well.

 

I did a 12a turbo with a TII turbo simialer to MoreMazdas. Infact he was my imperation, and I improved on it using a 12a mildported. The thread is called "Wacky's Turbo write-up". Good reading, took long time to write btw. Read through it fully and then ask more questions as needed. 12a and a turbo go together well if you do it correctly. Just don't over do the boost my friend..

 

You seem to be thinking an afi set-up on a 12A, the best way is build a hybred using a 13B housing to get the injector locations.

Not certain how far you can port a turbo before you have boost leakage problems. Ita limitation you should seek expert opinion on

 

Is a blow-through carb setup out of the picture for you? You said you don't have much money and that is probably the cheapest way to do it IMO.

I thought GSL-SEs were 6 port? Anyway that would be a good Idea. Budget turbo setup is the way to go. Maybe you can find a really cheap turbo II motor but if not go for it
