Has this been done before ?
Is it even worth it?

 

i am almost done with mine rob at rotary shack has done a few dozen i am sure.
BAd83 has one tons of people have done them. is it cost effective depends how you describe cost effective!

 

Worth what?

Not to be rude,but thats a lame question.If you search,youll see that MANY people have done this,as Yetterben has stated.
The stock TII turbo works well on a 13B,so of course its gonna work on a 12A.In fact,of all the stock car turbos,its the easiest and most appropriate turbo to mount on a 12A or other N/A engine since its shaped right and flows right for a rotary application.

As far as HP gains,thats only as good as your setup and tuning.You might gain 10hp,you might gain 100hp......or you might blow up on the first roll-on.It all depends on how well you set it up.

 

I dont know the power capable of a 12a turbo, it was simply a "might as well go 13b?" kind of question.. if the power gain is only like 45hp its not worth it IMO
I have no way of knowing

 

well there are guys running 600 hp 12a's sooooo(12a680rwhp or similar user name).........its as capable as your wallet.

 

you can make lots of power with a 12a turbo depending on your budget
and yes the stock 13b turbo's work great on the 12a motors.. i have a few good used turbos for sale if your interested

 

aha, i was close on the user name. Yes, Robert from rotary shack was the guy.

 

im just geting started TII in a 1 gen with a MSQ set up and any guy that's in to rx-7 they know it's worth the time
