Seat Ibiza Cupra into Mk2 8V

[DOA]

Ok, not like me to go around asking speculative questions but..... Basically I have a bit of money lying around and am dying to do a bit of a resto job on my old 8V Gti (MY 1988) and I have noticed a 97 Ibiza Cupra nearby thats going rather cheap with enough MOT left on it to get the bodywork on my golf up to scratch.

Now, the questions are (and yes, I have searched but want to be certain).

1: I know the ABF and gearbox in the Ibiza will go in, but can someone confirm if the gearbox and clutch actuation is the same between the two cars?

2: Will the front hub assemblies including brakes definately fit on the Mk2 (I know the PCD is the same as the golf, that it uses 280mm discs). For that matter, is it possible to drop the subframe on the Ibiza and pop the lot in the golf (using the existing spring/damper units). The last one is my preferred option as it means I can put the 8V back in once the bodywork is done while I do a good check over on the Ibiza engine and tidy up the subframe, wishbones, hubs etc along with a bit of welding to stiffen things up.

3: Is the Ibiza Master cylinder compatible with the golfs servo unit?

4: My research shows the Ibiza may have a transponder/immobiliser built into the ECU. Anyone know if this is correct? Not a problem if it is, it just means megasquirt and a custom loom will be on the cards giving some room for further mods at a later stage once I have proved them out on someone elses engine (long term WIP). I am presuming that, since the golf is a pre-90 spec, the Ibiza loom definately wont plug straight into the fuse box without me changing the existing loom, if thats the case a new loom would be done regardless.

5: Anyone know if the power steering from the Ibiza will mate up with the steering column from the golf (same splines at the UJ etc) if I transplant the full subframe from the Ibiza into the golf?

6: Fuel system wise, anyone know if the pump and tank from the Ibiza will fit to the golf floorpan or failing that, if the golfs digi system will give enough pressure for the ABF's digi system (I presume it will but worth checking first).

7: Does anyone know if the Ibiza exhaust system will work with the golfs floorpan up to the rear axle (I will be using a CAT due to the age of the engine and a desire to go through MOT's without mucking about lol).

8: Any other thoughts (other than find a toledo, avoid k-jet etc etc etc lol).

At the moment the plan is to keep the golf as a road car but with a slight upgrade to the power and brakes. It will be getting cleaned up regardless but the fact that I can use the Ibiza while I do that and then strip it for bits which can be used in the golf without having no car to drive for an extended period of time makes life a lot easier.

Thanks in advance for any input

Get ecu immob delete £55 a lot cheaper than megasquirt and will get you on the road quicker..

You wont need a CAT as they weren't a legal requirement until about 1995 or 1997 (cat requirements go on the car not the engine)

The subframe will bolt right up but the hubs may need modding to fit to mk2 suspension but im not 100%

just sitch the key through the inductive loop, fit the trasnponder box and ecu and it all works,  or you can just code a new key in and have it cut to your locks

I don't think the cable fitment is the same between the Ibiza and the Golf, but you might be able to get a threaded end put on the cable and avoid having to pick up a new one from a Toledo.  Try it - the padel end and distances will be pretty obviously right/not right.

2: Will the front hub assemblies including brakes definately fit on the Mk2 (I know the PCD is the same as the golf, that it uses 280mm discs).

IIRC there's a lot of Polo in the Ibiza, so you may well come unstuck on this one.

3: Is the Ibiza Master cylinder compatible with the golfs servo unit?

No idea, but a new 22mm one isn't dear.

4: My research shows the Ibiza may have a transponder/immobiliser built into the ECU. Anyone know if this is correct? Not a problem if it is, it just means megasquirt and a custom loom will be on the cards giving some room for further mods at a later stage once I have proved them out on someone elses engine (long term WIP).

As per Danny's comment - pull the whole loom and keep the key and loop - gives you a handy security upgrade if you want.  I seem to recall on Danny's Golf we clipped the loop over the lock barrel and glued the transponder to the key - works as per OEM.

5: Anyone know if the power steering from the Ibiza will mate up with the steering column from the golf (same splines at the UJ etc) if I transplant the full subframe from the Ibiza into the golf?

See Polo comments, although it's supposed to be more Golf-y in front of the front bulkhead.  Ibizas keep their value better than other SEATs hence I haven't had much experience with them. 

6: Fuel system wise, anyone know if the pump and tank from the Ibiza will fit to the golf floorpan or failing that, if the golfs digi system will give enough pressure for the ABF's digi system (I presume it will but worth checking first).

As per Polo comments.  I'd say very unlikely.  OEM G2 system should be fine, although I've seen some folk putting in-tank G3 pumps into their G2 tanks as it loses the underfloor unit.  I still have an original unit in mine.

7: Does anyone know if the Ibiza exhaust system will work with the golfs floorpan up to the rear axle (I will be using a CAT due to the age of the engine and a desire to go through MOT's without mucking about lol).

Polo issues again.  I wouldn't use a cat.  Why would you?  Makes no sense.

8: Any other thoughts (other than find a toledo, avoid k-jet etc etc etc lol).

Don't discount the OEM Digi 3.2 in favour of standalone management such as Megasquirt, unless you're going lairy cams and ITBs.  It has a lot of 'give' in it.  There is even some suggestion that with a vacuum acculmulator it might run ITBs too.

Just to add to DH's comments (I've just picked up an Ibiza to transplant into a mk2 and am asking the same questions- RJ is the master of ABF info, most of the answers below are answers he's shared):

Not 100% sure on the whole subframe swapping over but the 280 brakes and hubs will swap over. Master cylinder will fit but as DH said for the sake of a few quid buy a new one. The fuel tank won't fit (wrong shape). The gear shifter and cables you'll want to keep.

Don't use the CAT but you'll need to weld a Lambda probe into the exhaust system.

Regarding the key take the transponder from the key and glue it to the ring that sits on the ignition barrel of the donor car. Attach the plugs that it comes with to the fuse box.

Lol, I knew who you meant (shame he has dissapeared off here  ).

Sadly the car sold just before I got to it but the idea is firmly rooted now Im back in the land of the employed after being a skint student for 5 years and have the time/inclination to finish off a mates ABF transplant that I started 3 years ago. If I could find one for reasonable money I would go for a G60 transplant (love supercharged engines and as much as they get a slating for reliability, the G-charger is a cracking piece of kit in terms of efficiency and has more than enough potential for the Mk2 chassis) but the thought of dropping the whole subframe/gearbox/engine package in and gaining power steering and decent 4stud brakes all in one easy go is telling me that going for an ABF will be a nicer solution in terms of simplicity and it still leaves me some options for further development. Of course if a G60 corrado came up at decent money.......

Yes, what a terrible shame.

For the above you could also find a Cordoba ABF - it has what you require.
