Title: engine conversion 1.8 8 to 2.0 16 abf syncro
Post by: TANK on 23 February 2009, 12:00
i ordered a new engine when it arrived it was a seat i no there the same engine but as my machanic was fitting it he said i need lots more parts
the engine came with block loom box he has said i need "you need lower rad hose, both matrix pipes, the engine loom, car loom and ecu from a mk2 golf gti 16v engine bay power loom"
"the loom and ecu you have is from a seat and the power loom and half the car electrics are intergrated in to the loom, you could do it with this loom but it would take a sparky a week to build a loom for it and prob cost about a grand so its better to find the right one"
im a plumber and no naff all about engines can any help is he being lazy and trying to make the job easier for him self

for the radiator, tell him to fit a front MK2 16v front coolant flange and thermostat housing, then your old rad can be used.  Old matrix hoses will fit right onto the SEAT pipes.

as for the electrics side, this is the sticking point. sounds like your MK2 is a pre-90 right?  if so for plug & play-ness a complete post-90 MK2 in-car and also engine bay lighting wiring loom is required, then the SEAT engine loom will plug right in.  Its either that or the SEAT engine loom needs to be spliced into the MK2 engine wiring loom plug behind the fusebox, whichever your mechanic is more enclined to do.

Other option is to run it on MK2 16v engine managment, but ideally you want to use the SEAT stuff if you have it to hand.

im doing this on a budget so this cheapest best performance option

tricky as the syncro has extra wiring for the rear diff n stuff... not really in a position to advise on that part of things, danny or diamon hell should be along shortly to advise hopefully.

given the choice id prefer to 90spec the car, and plug the seat engine loom in, but you would need to reverse-engineer the syncro part to make sure all the diff bits work as they should?

Other option is as i say splice the abf loom into the fusebox using the old engine plug, which isnt that dificult but you might end up paying thru the nose. Print out my fusebox FAQ though and pm me your email addy and i'll send pre & post90 MK2 diagrams + ABF engine loom, print them off too and the sparky should have an easier time of it.  Once you strip the engine loom down there arnt many wires that need to be spliced, if you kept as much of the pre-90 engine loom as possible and onyl fit the ECU bits n pieces.

Really you need to have a long conversation with the mechanic, at the end of the day he is the one having to do all the work so you want to keep him happy :grin:

Problem with going k-jet is you need the k-jet main pump & fuel lines, metering head, inlets etc plus you still need the enghine bay loom as well, but at least if you find a pre-90 one it'll plug straight in and work. (assuming the syncro bits are integrated with the lighting loom?)

couple of questions first

1)  out of whitch seat did the loom come from,   the cordoba looms look a bit of a pita to use compared to the toledo and mk3 golf looms.
2) whitch gearbox are you useing ?  cabel change or rod change

my enigne loom is currently doing nether of options listed below,  the fuseboard seemed to want to play billy suggers when i connected the loom up useing loose relays in holders it ran fine so that got tidyed up and cliped on top bit of a pain at times but been working just fine.  tho as i have an almost comlete 90 speck conversion inthe shed and a couple of abf looms i think i'll be convering the car to 90 spec at some point

iwould say it came out of a ibiza as its a abf engine dont no what else they put it in and i think its a 97 if that helps

I think the original poster has bitten off a big fat chunk of too-much-in-your-mouth-to-even-think-about-chewing-on-it.

Doesn't matter what the gearbox is, or what the loom is.  There's a bucketload of custom fabricated parts you're going to need.

thats just spooiling the suprise,  tho there is another one comeing up,    020 syncro boxes  have clearance issues on 2ltr motors,  the other 2.0 16v lumps dont fit without adjustment  so dought the ABF will even bolt up to the box unless  you do frountline style block mods.

the proper treat is the exhaust tho.   that'll be a mare  esp if left rod change

ah yeah that bit completly slipped my mind, even though I read your build thread over on the syncro forum  :grin:

the engine is in gear box in all married up exhaust manifold etc done its just the issue with the looms
ya iv had a few probs with this not half as many as i had with the evo stroker conversion in my pulsar

thats good news then, you're well on your way to getting it going :cool:
hopefully with all them diagrams and stuff you'll be able to get it sorted one way or another, theres plenty help to be found on here if you run into any other problems!

In your position I'd use the ABF managment since its all to hand, and its just the better way to go. k-jet on an abf is never going to be perfect as its designed for a different engine!  I'd also 90spec the thing, its just the syncro part of the loom I'm not sure about. I have a rallye 90spec wiring diagram but its all in foreign which makes it tricky to figure out, and I'm not sure if its the same as on a normal syncro anyway.  Dan is your man for this :)

well your on the easy bit now.     

easyest way is to find a mk3 gti loom, it's not intergrated well at least the eraly ones arnt  and it fits into the bay easy as it's the right shape then all you have to do is swap plugs and add a couple of relays,     if get keen i'll go and look at mine later and see what goes where on the syncro bit of the loom

Post by: rubjonny on 24 February 2009, 14:55
id be interested to know which loom (engine or lighting) the syncro bits come out of, and what if anything actually runs all the way to the fusebox :)
that and if there is anything electrical on the rear diff or is it vac only?

Post by: danny_p on 24 February 2009, 16:19
ummm  had mine out to have a look when building it.


the reverse light switch on gearbox if diffrent ( rather a lot as well ),  some of the syncro specific loom is in the enigne loom so you have to stri that back as well.

then this bit of loom goes from fuse box to rear diff whicth also gets vaccume thought i had some piccys of it  but can't find the one i'm after.

just had a quick check in etka   the fusebox in the syncro is the same as everything else as expected so.  think i'll pop out tomorrow with a copy of the fusebox faq  and scribbel on it where the syncro has stuff pluged in

saw your post on vw syncro,  they don't like me or 16v motors

figureing out the loom is going to take more effort than previously thought, there are multi variants for the g box and rear diff.  i have 3 separate versions here.   can sort you a loom to get it running nicely tho.

quite a few ways of doing it pm if want a modifyed loom or the info to do one

there are a quite a few 16v fans on vwsyncro. Ive never got the impression that you are disliked danny- the site is far too quiet
