dubsy Posted December 3, 2009 Report Share Posted December 3, 2009 (edited) it all depends on the type of throttle body you use currently wether its drive by wire or flyby wire if its drive by wire the agu code would be easier to fit as this uses a throttle cable where as the bam code is flyby wire. for the conversion you will need engine, front loom, ecu you wont need the rear loom as the transponder can be bypassed and you can keep your clocks, all engine and gearbox mounts will have to be custom fabricated, as for gearbox its much easier to use the 02a found in the mk2 and 3 16v abf golf gti rather than the 02j found in the mk4 golf gti as its cable operated rather than hydrolic, if your planning on running bigger power then i suggest you upgrade the clutch and flywheel to a g60 flywheel and vr6 clutch as the dual mass clutch on the 1.8t,s has a tendancy to give up the ghost pretty quickly, as for drive shafts you can have them custom made but its much cheaper to use mk3 16v ones and have them cut and welded i know plenty of people who do this and run them on big bhp power cars so there hardly gonna fail on a polo. other things you need to consider is cooling such as is the fan in your polo gonna be able to cope keeping the engine cool if its a 2 speed it should be ok also is your radiator big enough another thing to bear in mind is an intercooler, its easy to go on eaby and buy one cheaply however because the engine will be so tight in the bay of a polo the inlet and outlet of the intercooler may need to be altered which may mean having a custom intercooler made which is what im having to do and they aint cheap. you may also have to relocate the battery and expansion tank bottle to the boot to gain space as for brakes the easiest and cheapest option is to upgrade to the 280mm g60 setup which can be bought for as little as £150 on eaby and edition38. hope this helps Edited December 3, 2009 by dubsy Quote Link to comment Share on other sites More sharing options...
st200_john Posted December 3, 2009 Author Report Share Posted December 3, 2009 helps alot, but im not familiar with all the engine and car codes.can i not fit a front mount intercooler down by the bumper?whats involved with the wiring and do i have to get custom driveshafts?thanks john Quote Link to comment Share on other sites More sharing options...
dubsy Posted December 3, 2009 Report Share Posted December 3, 2009 (edited) for the wiring all you need is the front engine bay loom from the 20v engine as for the intercooler yes it would be front mounted but it may have to have the inlet and outlet in custom positions on the intercooler and as for driveshafts if you use an 02a gearbox you can use the drive shafts for that box and have them cut down to size and welded up Edited December 3, 2009 by dubsy Quote Link to comment Share on other sites More sharing options...
st200_john Posted December 3, 2009 Author Report Share Posted December 3, 2009 so using those drive shafts is the easiest thing to do?How much does a place charge to fab engine mounts and drive shafts? Quote Link to comment Share on other sites More sharing options...
dubsy Posted December 3, 2009 Report Share Posted December 3, 2009 its not as easy as that the the mounts and shafts would have to be made up as the conversion was being done with the engine out and new engine ready to go in you couldnt make them up on request without this they are bespoke items Quote Link to comment Share on other sites More sharing options...
st200_john Posted December 3, 2009 Author Report Share Posted December 3, 2009 havent psi done the engine mounts before ? So they might be able to make some. Is it difficult to swap the looms? Quote Link to comment Share on other sites More sharing options...
dubsy Posted December 3, 2009 Report Share Posted December 3, 2009 i would very much doubt that they would remember the exact measurements but its worth a try asking them, as for the front loom its not a big job but im not doing the electrics on my 20v conversion a guy called andy outhwaite is google qpeng it has a lot of info about the 20v conversion on the site which may help you Quote Link to comment Share on other sites More sharing options...

dubsy Posted December 3, 2009 Report Share Posted December 3, 2009 what part of the loom do you need? I know it will be injections. all the exhaust. but will they have to intergrated into the original ecu?you will need the entire front loom which means all lines to the coilpacks, battery, lights, lambda etc its all one peice in a sense, if you need a pic of what you need i will try to put one up at the weekend, all of which would be used with the 20v ecu Quote Link to comment Share on other sites More sharing options...

penry Posted January 17, 2010 Report Share Posted January 17, 2010 i agree within 5 minutes of talking they were asking me on how id like the engine to look, polish, chrome, powdercoat most people are still scratching their heads working out how they are going to get the engine in top top guysThread resurrection here! Im thinking about management for my mk1 now, after being sold on qpeng plug and play for ages! But its £850 and then id still like to get it fine tuned on the rollers. Im not good on the wiring side so im cacking it a bit but OEM keeps cropping up with people saying its not too difficult and miles better. I just have no idea how the AGU loom and ECU splices into the mk1 loom? Quote Link to comment Share on other sites More sharing options...
