For some strange reason I have the urge to build a naturally aspirated 12A with fuel injection. Is this going to prove to be next to impossible or very expensive or what.

Please voice your honest opinions.

Has anyone here ever heard of such a thing?

Has anyone here started out from scratch building their FI system or is everyone here upgraded the factory stuff?

……OR……..

Am I as nutty as the guy with the thousands of dollars worth of Chevy V8 in his third gen?

Thanks,

You could do it, but it would require alot of custom work. Everyone I have ever heard of with FI on a rotary has either a 13B or a 20B.

the conversion is possible, as for custom work it all depends on what you are going to use. me and a couple friends built an 84 gsl and turbocharged it, the engine is factory high compression with jay-tech lower intake manifold,jay-tech throttle body adapter. the only things we had to customize was an oiling and water system for the turbo,downpipe and exhaust manifold. so if we would of not went turbo there wouldn't of been any customizing needed!

also let me add we used and old haltech ecu and wired everything.

It sounds like an interesting project to me. If you have the ability to make the intake manifold yourself, then you could try to source an outdated aftermarket ECU and some rebuilt FC 550cc injectors to possibly complete the project for less than $1,000.

its a piece-o-****

simply take your selected 12A in whatever port form you want. Bolt on a IDA Intake manifold, bolt on the likes of an INJECTION PERFECTION IDA throttle body and put a 13BT front cover on the motor with a 13BT CAS for the ignition pick up, 13BT coil and ignitors, its a pretty common set up down under.

you'll need 4 x 550 for a street port, for a bridge port or bigger you'll need 4 x 720's or 4 x 800's

I figured you fellas down under would have done something like this!

Hmmmm.......

If I could just get the military to send me to Australia or New Zeland for a month or so

HWO

go to hitmans page, there is some info there about injected n/a and also his 12a extended port injected motor

13BAce

Yeah, they like to have everything custome made. Don't ever let Shane find out that you're buy a turbo or intercooler kit.

HWO

Actually it's all available stuff, just your run of the mill IDA style manifold and a IDA pattern injection manifold with the provisions to run 4 injectors

There is a guy around here that has a street ported FI 12a in his spitfire, wish I would have looked a little closer at it though....

I guess the car really moves.

Looking into it it seems that all the peices are ther in Austrailia just waiting to be bought.

Shame that they get all the good stuff for the non-FD rotaries.

How much is a round trip ticket to down under?

(haltech advertises the E6K for 1145 AusDollars that comes to 550 somthin USD!)

e-mail Matt Leicher aka The HITman, he is an agent for the throttle bodys and should be able to sort you out everything you need, he can also send it to the US for ya

Just in case anyone cares I have found some more info.

Seems that a company out of CA called TWMinduction (link:http://www.twminduction.com/ )makes all sorts of neat stuff I thought could only be found down under. They have FI throttle bodies to fit just about anything you can imagine. Including weber, Dellorto, Mikuni and solex carb manifolds. They also carry intake manifolds for both 12a and 13b of the short runner side draft variety.

Seems to me a theoreticaly ideal setup would be their intake manifold and two 40mm TB's. This way you could run 8 injecors allowing for all sorts of adjustments and such for idle and secondaries AND each intake port would get its own throttle butterfly and primary and secondary injector!

So tell me the folly of my thinking and lead me down the correct path here......or tell me if I am right.

thanks

stick to a dual 48-52mm set up, Hitman has played with quad butterflies, think they were quad 38mm on a 13B Bridge port, lost like 60HP, didn't work too flashly aye
