Hi,

1st post on this site ......

I am currently involved in designing / building a Kit Car. To cut a long story short we have sourced a Twin Turbo (FD3?) rotary engine from '92 / '93 RX7.

I like the idea of using the engine as its big power and relatively compact, so was just wondering if anyone on this foruim has / is using a rotary engine in something other than an RX7?

Also, any advice and pitfalls removing and re-installing these engines would also be appreciated. The chap whois removing the engine has said something about the engine wiring loom being more complex than he would have anticipated?

Am based in the UK if thats any help.... Any help woud be appreciated.

Kind Regards,
Mark.

Very interesting. Good luck on the project.

There are conversions out there using the 13B's like for the Miata which is fairly popular:

I don't know if they have a kit specifically for the 13B-REW though. There have been others over the years talk about doing something like that with the current kit cars, but I've never seen anyone actually go through with it.

Well, the harness has connectors for the sequential turbo control as well as the emissions components which are a majority of the connectors. Depending on the engine management setup and the turbo configuration you plan to use, you could possible eliminate most of the connectors from the harness.

The main difference is you might have a few less components on the engine like the EGR and AWS system. Pretty much everything else should match the USA spec of the similar year.

I don’t know enough about these cars to give much useful info.

What kind of kit car are you putting it in?

To cut down on complexity you could run carburetors that would be a lot less wring to deal with. But the carburetors might give less horsepower. If you are putting it in a car that is light weight that is not a big deal.

A guy I knew had a kit car based off of the lotus super 7 that was running a turbo rotary with a blow through Webber side draft that ran about 220 horsepower, not a lot but the car weighed next to nothing. I was never in the car when it was running, but supposedly it was extremely fast, and very fun to drive.

Looks like I will be one of the first then?

To begin with I want to take as much from the car as possible, so that will mean:
- Complete block
- Wiring
- ECUs / stock Engine Mangement etc.

Is there anywhere I can go to get wiring diagrams and specs, etc?

Many thanks for your help so far...

Not really. Many have blazed the trail before you. Go over to the Locost forums at:

http://www.locostusa.com/forums/

And search through the build logs. Many have used Rotary Power in their cars. In fact, a lot of people have used the entire driveline from an RX-7, including all the spindles and hubs and the rear diff (fc/fd) or rear axel (fb/sa).

Without knowing what sort of car you are building (traditional Locost, mid engine racer, Ariel Atom clone) I can't really speculate any further on what you'll need.

One warning though - when you use a rotary powerplant cooling is critical - both oil and water. Plan for decent size openings for the radiator.

You definitely need the Mazda Factory Service Manual. Do a search in this forum on "FSM" and you should find some links to online PDF for this book.

Ive seen AE86 Trueno's with 20B's in them before, seen people swap 13B N/A's into B2200 Pick ups. There are a lot of options out there but it sounds like a really interesting project. Good luck!
