Yo! Just a musing, but I have been thinking about an engine swap for my Golf in the summer. It's been/is a remarkable car and as such, I want to reward it. I was always planning to remove the engine in summer and detail/smooth the engine bay, but if it's out it might make sense to use that as a time to drop in a more powerful lump. The initial thought is for a 2.0 16v lump, from a MK2 (or MK3, if it's the same engine). Primarily because they're cheap, I would like a VR but they seem to be mega-bucks. Anyway, the point of this post is to ask if anyone knows what's involved. I want to do this myself, and as such this will be the biggest thing I've ever done, so I'm starting the research now. So, let me know what you know! ;D Chris

This is exactly what I did, abf lump out of a mk3 gti into my 1.6 driver, there may be a write up in my thread in my sig (or there may not ). If your car is post 90 spec with the later style fuse box its pretty straight forward, you need engine, ancillaries, engine wiring loom, and mk2 gti fuel pump and fuel lines. Engine loom plugs straight into fusebox, fuel pump bolts straight to the bottom of the car (the studs are already there), engine bolts in on original mounts. Job done. For the exhaust I used the mk3 manifold with a decat pipe off ebay to connect it to the mk2 system. I may have forgotten something but if you need to know anything about the conversion send me a pm and ill see if I can help. Oh and the mk2 golf never came with a 2ltr (afaik), theres the abf which runs on digifant injection which came in the mk3 golf, passat and ibiza, and the 9a which came in the corrado and probably others I cant remember which uses kjet I think, or something similar. (someone will correct me if I'm wrong)

You will need a few bits with the engine a brief list:
Fuel pump Lift pump Fuel lines engine loom (post 1990 mk2's have same fuse box as mk3's) Fuel pump loom and relay ISV control box and loom. Your gearbox will be ok but better with mk2 16v Exhaust

Hitch is the man to ask Chris as he did this exact conversion - his is the 2.0 L 16V 150bhp jobbie from the mk 3. When I saw the car and asked him about it, he said that the later cars where much easier to wire in as the fuseboxes are the same! Easiest thing to do is to have a mk3 in the garage next to the MK2. Here is a pic of Hitch's install: A ridiculously quick car - just remember to take the brakes from the MK3 as well... Plus if you then 5 stud it, you can get Impreza rims on there... Rysz. EDIT: Balls beaten to it by the man himself!

I'm planning on doing the same swap soon, probably also in the summer. Swapping my 1.8 carbed engine for a 16v on injection. From what I've heard it sounds pretty easy. It all bolts in, no custom mounts needed or anything, and the wiring for the injection sounds strait forward enough. Mk2's didn't come with 2l's over hear, so you'll be looking for a mk3 engine really. Although if you can pick up the cams from a kr (pre catalytic converter 1.8l 16v) then it boosts the output a noticeable amount for not much cash apparently. Edit: beaten to it.. Also, this thread reminds me that I need to call my insurance company tomorrow and see what they say to the idea

Wow, great info guys.
I maybe should have mentioned that the car is an '88 Driver. What implications does that have on the electrics?

Best and easy to get a pre 1990 mk2 1.8 16v and keep the K-jet, this will have the same fuse box as yours.

Can't keep the K-jet though if it's a driver to start with. I've got the same issue, apparently there's not too much wiring to do to get it into any other car, just simple lives and earths, it's just knowing which you need to keep and which can be ditched.

Best and easy to keep the K-jet. Its a driver so itll be carb, not kjet. I cant remember what you have to do with pre-90 as I didnt have to lol, but I think it may involve wiring in the later fusebox or modifying the engine loom to fit the earlier fusebox.

No keep the K-jet from a mk2 golf 16v.
If you want to use a mk3 golf engine in an early fuse box you have to mod the loom, easy as not many wires.
Don't use a corrado/audi 2.0l unless you change the cams.

Take a look at this thread below, alot of its related to fitting the mk2 16v kjet injection to the abf engine so you can ignore that but theres alot of useful info in there and a bit of a guide on using the digi injection on page 2. www.clubgti.com/forum/showthread.php?t=133418&highlight=abf+driverAs for the pre-90 fusebox problem the easiest option imo would be to just rewire the engine loom plugs with the plugs from the early fusebox, theres only 4 main plugs with about 30 wires between them so its not a massive undertaking. Ive got loads of wiring diagrams aswell for the abf loom and ecu and the fuseboxs if you need any of them.

Oh and I forgot to say you'll have to wire in the fuel pump separately from the pump to the fusebox but its only 2/3 wires so not a big deal. Edit: One more thing, gearbox, I originally used the 1.6 gearbox which had good ratios but the clutch wasnt up to the job so ive recently upgraded to the mk2 16v gearbox which I think is the best option. Alternatively you can use the gearbox out of the donor car but this will be cable shift as opposed to rod shift so you will also have to fit the shifter which isnt too straight forward, plus the clutch may be hydraulic instead of cable in which case you will have to fit the pedal box aswell. Easier to just use a mk2 box.

Just to throw an alternative into the mix, Mk3 VRs with little/no test are dirt cheap at the moment. There was one local to me with long test but a scabby body on ebay for £650 BIN. Non tested ones can be had a lot cheaper, and AFAIK the conversion is no more difficult than doing an ABF 16v swap.
If you wanted to go 5 stud, you can wheel the complete front subframe out from under the Mk3, and bolt it up under your Mk2, and likewise with the disc braked rear beam. Also you could make some of your money back selling off some off the VR interior bits.

As for the pre-90 fusebox problem the easiest option imo would be to just rewire the engine loom plugs with the plugs from the early fusebox, theres only 4 main plugs with about 30 wires between them so its not a massive undertaking. No, the easiest way is pinching the dashboard and rear section looms from a '90 spec mk2. I did that when I converted an early petrol-powered mk2 to a turbo diesel. I stuck an ABf in my mk2 GTI. It's not difficult but you'll want to do it properly with the matched gearbox, hydraulic clutch, etc, etc... PM me if you need any help, and both the links in my sig should help, too.
