12a Extend Port Carbie Fed Efi Conversion

[boostin30s]

hi everyone, i have a 12A extend port 5 speed in my s currently non turbo and carbie fed. i have a turbo to bolt onto it, stock ht18s. but i want to convert it to fuel injected and have no idea what or how I'm doing it. please help me out with the easiest, cheapest way possible to do this. thankyou very much!!!!!

sorry mate, know nothing of rotaries, they scare me.

 

BUT

 

 

you should post some pics up!

 

:jamie:

 

good luck

Jump on Ausrotary.com and ask a few questions on there.

 

I'll eventually be going 12A in my KE25, but am sticking with a carby :jamie:

From my somewhat old knowledge of rotes, it's probably easier to buy a 12a turbo or 13b turbo package and drop it in. Unless you have some fab skills then you'll struggle with manifolds. Not a small job which ever way you go.

I agree with the above, if you want a turbo motor then buy a s4/5 front cut or complete motor and box.

 

Your current motor would have higher comp than that of a turbo motor and hence you wouldn't be able to run much boost.

 

If you want to do things bit by bit I would suggest: Getting a 12a IDA manifold and a IDA style throttle body and a computer to run it. Stick with that for a while and then when you want the turbo too - Get a S4/5 block and a 13b IDA mani to put your throttle body and injection on the 13bt.

unless you like your wallet being empty, id recommend leaving it non turbo carby.. everything is so much more simple and reliable!

 

if you really want to do it though, id also agree that a 13BT half cut would be the best option, mated to an aftermarker computer.

He drives a rota, of course he doesn't mind his wallet being empty! :D

 

Sorry, couldn't resist :jamie:

 

I was nearly going to suggest the IDA throttle body approach too, but you'd still need to do some fab.

 

Actually, rote's have a far less problem with boost and high compression than piston engines do. You'd probably be about to run a reasonable amount of boost through a normal compression motor without too much trouble.

All revolves around how big your budget is...but if you really wanted a Turbo Rotary engine then half cuts will save you endless fabrication time and hassles.
