Hi,
Im wanting to do a agg engine swap in a 1990 mk2! Just want to know if any additional engine mounts are needed or anything els! Like the wiring harness and additional parts to complete the swap.
-
If your engine is currently a 1.8 8v then it'll bolt straight in and run as long as you use the adaptor on the distributor.
-
Cheers man, and regards to the wiring harness, whats the go with that? Is it a straight plug n play or do you have to install the complete agg engine wiring harness, and if so is it a complex task?
Regards

I presume you already have an 8v gti then? If so the usual swap is to use the AGG/2E bottom end, refurb your current cylinder head and fit it to the 2litre block using the AGG/2E headgasket. Then use all the existing ancillaries off your current engine and drop it in - straight swap :) Do a quick search on your favourite search engine and there's loads of info on the distributor mod you have to do, but very straightforward.
If you don't currently have an 8v gti then you will need the whole lot from the mk3, wiring loom included. I presume your car is CE2 (is the hazard switch on the column?) so the wiring will pretty much plug straight in. Again, easy swap, but if you're doing a full engine conversion then you might as well go for something with a bit more poke, like an ABF. If you don't like 16vs then stick a G60 in it ;)
Edit; If you currently have a carb engine, either 1.6 or 1.8 then you can grab yourself a webber carb and block the injection holes in the head, think a 1p coin is a good fit. Not going to be as fuel efficient or powerful as a full injection swap, but should give a bit more poke for little effort.
-
if you use 2 litre bottom end with carb you would need an electric fuel pump as the 2 litre auxiliary shaft has no lobe to drive the mechanical pump.
-
what is the difference when fitting the current cylinder head onto the 2.0L block? or can you just stick with the current cylinder head on the AGG engine. Ok, well if i was to go with an ABF, is there any major changes in regards to the engine mounts and again will the wiring harness in this situation be a straight plug n play?? :smiley:
-
you need to tell us if the car is a gti or not???
-
sorry, yes its a 1990 mk2 1.8 8v gti!
-
Cylinder head is your choice, both fit.
Abf is a more involved swap as you need wiring loom etc. Physically mounts the same though and you can use your existing gearbox. Best bet is to have a search on the internet, both swaps are heavily documented and explained.
You should be able to get a full abf conversion for about 2-300 quid, maybe a bit more if it is low mileage and includes gearbox etc.
-
ok thanks, and in regards to the wiring loom, how difficult will it be to put the abf engine wiring loom in? Also will there be any additional parts required for the abf swap?
Cheers
-
If you use your existing gearbox and get a complete engine you shouldn't need much else, maybe better brakes.
Wiring loom physically fits into your fusebox, just have to do a few mods depending on what coil you want to use etc. Again, lots of info available in the usual places; here, ed38, clubgti - have a search :)

thanks! whats your opinion on the 8v vs 16v, cause i read on another forum and found that the 8v is a more reliable engines as if the timing belt was to slip or snap the 16v would bend valves and damage pistons. On the other hand, the 8v will not even bend any valves as it is an non interference engine, and parts are much cheaper than for a 16v. :smiley:
-
Er, given the correct belt change interval and servicing I don't think you have too much to worry about.. Being non-interference doesn't make it any more 'reliable'.
I'd put an abf in it personally, but it depends what you want from the car and how much time/effort you have to put into it.
abf is 150bhp straight out the box :) probably more with a decent exhaust.
