N12 Turbo Forums

I'm planning to upgrade my N/A engine in my N12 cherry with the EGI manifold instead of the crappy carb, but I don't know exactly what parts I need besides the EGI manifold and injectors and gaskets. I want to try this before going wild and converting to E15ET.

Any advice guys?

P.S. I'm not going for it straight away, it might take a few months or a year or so before I perform this upgrade, but it would be nice to know what I need to do/get/order/install/etc. to make the engine run with the EGI manifold.

Well... you need the whole fuel pump/lines/injection system. And the ECU/Loom out of an E15E engine. If you need an E15E ECU and loom i have them.

Not much difference if you go straight to the E15T . . . . except source all the bits from an E15T and include the exhaust manifold, turbo and dump pipe.....

All right, thanks! I hadn't thought of the fuel pump. What about the distributor, does it use a crank angle sensor or is it the ordinary n/a points distributor? Or the magnetic n/a distributor? (I've got both n/a types)

Great! Thanks for the offer! I will probably be needing those, but as I said, it might take a while before I get to it. Financial issues, you know. The renovation and respray were a bit expensive for my budget. But if you happen to have them still after a year or so, I might be interested in buying them.

To get parts all the way from the other side of the planet will probably cost a lot in transport costs btw. How much money do all these parts (not only the loom and ecu) cost in general (excluding or including transport costs)?

you could get a whole car for AUD$500-$1000

Ok, that's what I expected as the E15E has an ECU. I need to get one of those when I get to converting this engine.

Ok, but that would be a bit expensive to transport all the way to Finland... a box of parts is a lot cheaper to ship, I guess.

E15T's are available closer to home... See George in Greece, or "Insane Tuning", "Chezza" and "puffypuss" in the UK, "Bjorn325" in sweden, "gettu" in Finland.

For an E15ET conversion I would go looking for parts from my home country or Europe, good point. But I thought that an E15E conversion would be more interesting in the sense that I wouldn't have to go through a lot of bureaucracy to get it street legal with the E15E engine, and it would be the only injected non-turbo cherry in Finland. And if I replace the engine with an E15ET in the future, I have the advantage of the EGI manifold at hand.

If I would install an E15ET engine I would have to upgrade the brakes and the suspension as well to get it street legal. And that is going to be expensive, because suspension parts for the N12's are not easy to get in my country, especially the Turbo Cherry parts. And I have to go through a special check of my car to make it street legal, and that costs a lot of money as well.

If I upgrade to the E15E engine set up I get away with just the yearly Finnish equivalent of MOT as the British call it. That is because the engine power output does not rise significantly from the E15S setup (75 hp to 95 hp, as I recall). Anyway, this is how it is in Finland, you guys have quite different regulations over there.

I think I should have explained this earlier, sorry!

Thanks for the input guys. I still would like to find out how expensive those E15E parts are. Including the dizzy with CAS.

What kind of fuel pump is that? Is it connected to the engine or is it attached to the fuel tank? The n/a fuel tank would be a problem if the fuel pump has to be attached to the tank. In that case I would have to rig up an aftermarket electric pump instead?

yes, just as long as it delivers the right pressure and flow rate to the injectors. So it could be in-tank, or out of the tank, doesn't mattter

Ok. I know a store that sells electrical fuel pumps among other things. Thanks, that solves the pump problem! I don't want to start replacing my fuel tank just because of a fuel pump. Got any idea how much pressure would be sufficient for the EGI injectors? 0.3 bars or maybe more? Or less? Can I use the return line (for returning some of the fuel) or should I block it or something?

you got to make sure you match pressure and flow rate. Not sure what each of these are, but they are in the manual, which you can get on the forum somewhere....
