At the moment I have the engine in the engine bay bolted to a FD tranny with Turbo II bell housing & input shaft which moves engine back another 3/4' inch and offers bigger selection of clutches.

Then why did you use a Turbo II bellhousing? :)

It's been awhile (~2 years), but I believe that the starter is/was the main problem. The buyer for my engine brought an auto bellhousing to bolt a starter to in order to kick over the engine for a compression test, and if I remember correctly, said that the rear plate would have to be swapped to bolt to an FD 5M and use the stock starter. Sorry, but I don't remember any other details. I never got to that point myself, so I'm just going on information from someone else on this one. :)

If you need any help, don't hesitate to call any of us in the local club... While I can't speak for their interest, Harry's (HN) a master at the sequential turbos in the Cosmo, and Ted's done a think or 50 with the 3 rotor too... I've only done an engine replacement on the FD, but I know a good bit about the workings of the 13BREW..

I can also offer a place to host any of the info you collect in your conversion process.

I'm looking into a 20B FD conversion.

I have the itemized list that Pettit Racing sent me with one of their customer cars.


Right now, I don't know that many places that source the ignition coils (atkins for $450) and exhaust manifolds for a t04-based turbocharger (alamo, but it's $$$$$).

Any other places?

I think that you could custom fab an exhaust manifold for a t04-based turbo. I don't know if it helps, but Mazdatrix lists a 20B exhaust engine flange http://www.mazdatrix.com/e7.htm for $44. This might help. Find a good exhaust shop or performance shop to work with. They will be able to bend the tubing and weld it together with the flanges. Try to get a pic of the one from Alamo, maybe you can use that as a guide.
