4port 13B engine - Info.

[rei99]

After some year, I finally clean my carb, and see that the 13B is a 4port.
I read the Long\'s book, and saw that 4port 13B engine, on Rx-7, was just on the Turbo II.
Old owner said, times ago, that he caming from marine.... Could be?
It doen\'t seems too old, so I don\'t think it will caming from a Rx-3 or other...
Any idea? I could check somewhere for an engine\'s number?
Thanks!

Perhaps some photos might help, it could have been converted to carbs, photos will help a lot.

I think the 13b 4 port was used on the rx4 as well as the Turbo 2. I have a rx4 4 port manifold on my 13b in the FB.

There\'s some VIN number on it? I just saw the 13B upside.

Rx4 had 4 port 13b. I had one in my race rx7 1st gen built by wgt. It was very good.

But it\'s older, and very strange to found a new motor in Italy: this car was never imported ufficially, so also spare parts are unevaible... It\'s a mistery

the 1st 13b 4 port engine came in the RX4, then it was used in the RX5, then in the US RX7 from 1983. The RX7 turbo 2 is a 4 port 13b with low compression, the FD RX7 is a 4 port with low compression too.

Is there much to gain from swapping the rotors out from a turbo 2 to  a FD Carl? :Thumbs-up:
