1.8 kr into 1.3 mk1

Evening. After doing alot of searching around ive still got a few questions. The conversion is a 1.8 kr out of a '90 corrado, into a 1.3 '83 golf. At the moment im stuck on a few things

- which gearbox to use? Some people have said is fine to use the original mk1 box and shafts?
- can i stick with the mk1 radiator?
- inregards to the exhaust manifold, do i have to use a mk2 scirocco one?
- should i modify the mk1 loom, or pull the engine loom out of the corrado?
- also i read that because its not a gti shell, other things will have to be changed. such as fuel tank, and moving the os engine mount?

if anyone could shed some light on this it would be very much appreciated!
thanks
steven

Big block ie gti gearbox is fine I'm running cabby box on mine. Some are 100mm some are 90mm shafts most will say to use 100mm but they are expensive.

The drivers side engine mount wants moving back nearer turret and welding on, think it gets flipped too not sure.

Exhaust you'll want a 16v conversion manifold and either a following system
Ie Ashley manifold and exhaust or have custom made, mine is stainless and cost 300 with lifetime garentee. Read up on manifolds

Fuel tank you'll need a lift pump and outer fuel pump etc found on gti unless you run carbs then your fine with tank and setup need a bike pump though.

Wiring I can't help

so i need to source a gti box and shafts?

can the corrado manifold be used with a custom downpipe?

Yeah mate source box and shafts or if you have rado box use that.

And yeah if you can weld/not fussed how nice it looks you could utilise it.

1. any 020 box you like, plus 1.5-1.8 mk1 or cabrio gear stick and all the linkages in the bay. might even need the rack too

preferably a gti box for sporty ratio, which one exactly depends what you want. i loved the short ratio 1.6 gti box on my kr cabby, acceleration was rapid but top speed and motorway cruising not so great.

cable shift box also an option, but will require hydro clutch setting up or SEAT abf/tdi cable conversion.

2. yes, but fit a big block one. 1.8 one is easiest and cheapest, get the pipes to go with it as well as shroud, fan and loom. new rad dirt cheap:

3. either fit a mk1 kr conversion manifold, or fabricate something. on my cabrio i had mk2/3 16v manifold with top half of mk2 downpie welded to bottom half of mk1. needed a fair kink in it to clear the linkages. going cable shift makes this easier. scirocco 16v manifold and downpipe would work,if you could actually find one

4. if you want proper isv control you'll need a kr loom of some kind, as it will have the controller part in it.  the ecu loom splits off and can be dropped right in. if you have later mk1 blade fusebox mk2 pre-90 16v loom ideal as it plugs right in, just needs tweaking to fit mk1 bay. otherwise 90spec or corrado is also fine just needs splicing. if you were planning to use mk1 aav mk1 gti loom is all you need, just mod lengths of stuff so it reaches.

5. yes need to move mount, loads of info on that. fuel tank either fit mk1 tintop gti, or get late mk1 cabrio/scirocco or g40 shape polo lifter pump and under car reservoir. then you need mk1/cab/rocco k-jet main pump plus a mk1/2 fuel accumulator. mk1 fuel lines bent over to driver side, or make your own, or buy crazyquyiff mk1 16v line kit. use mk1 metering head feed & return lines plus mk1 gti filter bracket, pre-90 mk2 16v airbox and any kr metering head, wur, 5h injector and fuel lines setup.

see my mk1 cabrio build thread for lots of info on mk1 16v swap, including the best way to get the dizzy cap to clear the brake master cylinder (in my opinion)

is it possible to use the mk1 box? time is tight on this conversion and the less the change the better ideally.

could i use the rad out of the corrado? ive the whole car as a donor for anything.

wicked, i'll use the rado manifold, and fabricate a downpipe.

rubjonny said

loom options

i'll be using the corrado engine loom. the mk1 is '83, can i still use the mk1 fusebox or will it need the rado one?

any links as to where to move the mount? is it crucial, or can it be done by eye?
what would be the simplest setup? all the engine bay stuff will be coming from the corrado (metering head, wur, injector, etc) but im a little confused as to what needs to be changed. do i just need a lifter pump and undercar reservoir, and use the original tank?




i'll definitely check out your thread. thanks alot for your help, means alot.

no, 1.3 box is wrong shape and wont fit. corrado one will work but its cable shift and hydro conversion time with that as above, plus you'll need later cabrio/scirocco 100mm shafts (will need mk1 90mm or 100mm shafts no matter what box you go with, your small block ones are no use)

yup, take it and all the pipes, shroud etc

you can if you splice the corrado loom to the mk1 fusebox. lots of info on this around here, see my sig g2krecuce1.pdf for a wiring diagram for your fusebox. g2krecuce2.pdf is the 90spec wiring diagram, use them both to help figure out how to convert it, feel free to ask questions if you get stuck

as i say, loads of threads on this. there is a notch on the chassis leg you can use for alignment. the old bracket will work but you have to flip it upside down, plus it'll need a bit extra metal welded onto it.

you'll need a pre-90 mk2 airbox as the corrado one is far too big, everythign else in the bay will be fine. just need mk1 k-jet fuel lines from the fuel pump right to the engine bay. if you use the lift pump and reservoir it'll fit your existing fuel tank, but you might have to faff a bit to get it to fit along with the accumulator. shouldnt be too hard just need to think carefully. if you can get the mk1/rocco accumulator as well that'll help as its much smaller

hello again. sorry about the lack of response, lots going on and the golf always gets pushed to the bottom unfortunately. however now its not under so much time pressure so i can relax ha.

to aid simplicity (and noise ) ive decided to run it on twin 45 webbers. does this mean i can leave all the original 1.3 tank/lines/pump as they are?

also if i buy these http://www.ebay.co.uk/…m43b2d92628#ht_919wt_1047 which is the best box to get so they marry up?

thanks for your patience.

yeah you'll just need to wire up an electric pump, you can use the kr ecu to trigger a pump relay safely, or use a k-jet 8v relay without rev limiter that would also be a good way to do it.  any mk2 gti box would do you
