1.2i to 1.6gsi conversion???

[youcanonlydream]

i dont want to change the ecu,will the 1.2injection's ecu be similar to that of the gsi or will i have to get webbers straight away????
as far as i can see its more or less a straight swap from a 1.2 to 1.6....is this correct????Id be glad if someone can help!Cheers!

if you have injection already and you want a 1.6i setup then you'll need a few things...

ditching the 1.2i tank with it's infernal pump is the first of the barsteward jobs! :cry: you'll want to use the GTE/GSi pump with a GTE/GSi fuel tank, which may require re-routing and extending the original pipework :|

or you could stick with the original tank and pump and go for webbers or a standard carb.

Dropping the 1.6 in shouldnt be too much of a problem as the same engine mount points are used, although you will need an F13 gearbox (should still be attatched to engine) and the drive shafts/CV's etc.

As for mating the loom from the 1.6...it all depends on whether your going for the full GSi, with injection or ditching the injection...although I could be speaking through mt arse, coz I've only ever done a 1.3 carb to 1.6 injection b4 8)

the 1.2i pump/tank is fine for the gsi engine unless ur gonna do some mods to it. if you do just fit a cav2L pump onto the tank insted of the 1.2i and thatl b good for a 2L 16v then aswell.
you can keep the ecu etc in the car and just wire the gte/gsi ECU/lllom up aswell.
all u need is the engine/gearbox and injection system off the gte/gsi pretty easy really

OK!Cheers for that lads!i will be trying it very soon.........this weekend infact!!!!!!!If theres any more ideas keep them coming!!!Cheers,Phil.

the SPi pumps only run at 0.76 bar

GSi lumps run around 3bar

i think u'll really need a GSi pump - tank might be ok tho

[Dicko]

thats right ye, it will run but ul loose a few bhp. you wouldnt really notice any problems unless u did a few mods which required it to use more fuel. jus put a cav pump in, much easier than fittin new tank/pump/lines etc

[Pan@SW-CC]

ok ok...have you guys run a 1.6i or higher (with the injections system) or higher with the spi tank? Coz I did and it just didnt work! If your starting the build, go straight for the proper tank!

I even tried adding a GSi pump in line with the internal pump and it just didnt provide enough juice...c'mon...who wants to loose a few BHP when there's perfectly good VTR's to beat! :wink:
