    Icon10 fuego injection finally finished

    Today I finally finished my fuel injection conversion to my fuego.
    Only took a weekend The best performance upgrade i have done to it yet.
    Still have a few hours of stuffing around to go but from the short not so hard drive I have had in it so far you can really notice the difference.
    Pics coming soon for those interested.

    The bottom end is still fuego, but the top end is 21 with a 21 factory computer.
    Pics coming soon, been getting home to late this week to take good fotos.
    but they are coming

    ah - that must have been you that got the head and computer from that silver R21 out at pickapart in Kilsyth! Did you shave the head to up the compression? a 2.2 head on a 2.0 block would result in a very low compression i would have thought

    Yeah I got that head off that one. not the computer though, whoever got that is gonna be disappointeds, I had a look at it and the internals are coocked, the rest I got from reno spares
    The two heads are identical, except ofcourse for the intake ports. The 21 gets its 2.2 litres from a slightly shorter stroke
    So compression is about the same. Mines is probably a bit higher, they took a fair pit off the head whe it was recoed

    the 2.2 is a longer stroke. same bore. I would have thought that the combustion chamber volume on the 2.2 head would be larger to compensate for the larger volume of gas being forced into it? hence an even lower compression with the 2.0 block. But if it runs well, alls good! But then again, they may well be the same, as the EFI motor can run a higher compression due to the knock sensor than the low comp Fuego, so you may just have the Fuego compression ratio. You could then up that a bit if you want for more poke, as the knock sensor/computer will allow for it.

    Would love to have a look at your handy work - doing that conversion (I already have all the bits for it - just need to get another Fuego - or sell them to Mistareno if he ever answers me - yes you Richard ) has been on my wish list for years!!

    I am pretty sure there is minimal difference between combustion chambers, although I did eyeball it Although the 2 mm lip around them is almost flat with the head now I think they had to shave it a bit to get it flat. So I wouldnt be surprised if it was slightly higher than fuego comp. Ill do a comp test and get back to you anyway

    In a way it is unfortuate because I would like to Turbo it next when I have some spare cash (yeah right spare cash)
    Ohwell, decomp plate it is.

    It all fit in fairly nicely, had to get rid of the stock fuego airfilter, and cut a bit out of the box section that the headlight is mounted into to get the intake mainfold to fit but other than that it sat in nicely.

    I ripped aout the A/C system too which makes the drivers side of the engine bay empty.

    Yeehaaa...

    I would love to see it also, as I have been wanting to dod a similar thing, but I keep saying I'll wait till the engine dies, but it keeps going strong so I live with it...

    BTW- Haakon, hows my engine going, I'm getting jealous

    The main reason I want to EFI mine is to allow for a bit of external pressure down the track..

    I hope you got the camshaft bores machined when you got the head done. I have heard that it requires some machining if you get the head resurfaced or else the cam will be installed slightly warped and chew out the housing...

    Nah I didnt get the camshaft bores redone, the head wasnt warped, it had some bad pitting in it which is why the reco place had to skim it a bit, that is what I meant by flat

    sounds pretty normal for old euro alloy

    it has always amazed me how jap/aussie alloy is so different from euro alloy

    euro alloy always comes up dull when clean and even has a different sound when you tap it

    i was amazed though when i got my block machined out that it didn't have any signs of porosity in the casting which was good to see and my heads came up like new and not a single sign of corrosion anywhere to be seen

    Yeah Jensen, I have a devil rear box courtesy of autoparis and I cut out the middle muffler and replaced it with a clio sport hotdog
    Sounds pretty cool now with that exhaust and the new induction noise not previously available on the shitty carb.

    Have been reading this thread with interest.
    What does Vicroads say about the conversion?
    What does your insurance co. say about the conversion?
    I have been told this EFI system is a DELCO (GM) derivative and that it doesn't take much to re-program the chip.
    Do you use PULP?
    I look foreward to seeing the Fuego at the next All French Car Day!

    My Insurance company tick boxes for mods are very general, I just marked it down as an EFI upgrade. It runs anything other than diesel and lpg.
    I have yet to try it on pulp, wil be interested to see the difference if any.
    I finaly had it completey ready to go last nite so I got to take it for a thrash. Keeps pulling up to 7 grand. Very nice indeed

    I think it is a Renix system, it does however use a GM map sensor. I didnt have to reprogram anything, I think powerchip has a chip for the ECU i am using but from all reports I have had from other people they reckon the performance gain isnt worth they money they charge.

    My plan is to run an aftermarket ECU eventually but that will be happening with the turbocharger when I have cubic money to spend :p

    Renix is the Reno badged edition of Seimem's EFI systems. Can get power chips, but easier to get a R21 Turbo ECU from pommyland when the hairdryer gets bolted on - the mapping on the Turbo ECU is pretty extreme in "standard" form apparently.

    Gunnawarra - looking for excuses (not that I really need them at this point ) to drive the 406, and I'm in Hawthorn - what time you get home from work and where are you?
