loopmuscle Posted September 11, 2010 Report Share Posted September 11, 2010 decided to make this thread so everyone can stop asking how to do the conversions.also find out why everyone says polo gti looms are easier.done this conversion three times now so iv got the idea how you do ityou will need polo gti engine polo gti looms inside and out polo gti or lupo gti ecu and if you have cable throttle get the gti, sport, pedal boxelectrical CENTRAL LOCKINGeasiest way to do central locking is to use your old loom( if it has central locking) strip the loom down starting from the drivers side door connecters seperator the central locking wires from the other wires.do the left side door connector firstly to the fusebox and also to the drivers side wires where they attach. secondly down to the boot of the car where they lead to the boot lock and interior lighting.do the same to the polo gti looms while also taking out the air pump pipes.the boot wires need to be chopped or either the pins need taking out the connector blocks once done put the old looms to the gti ( best to go fusebox first) the polo gti looms may have extra peices going off near to the rear speakers these where the interior light sensor connects and are no longer neededonce all fitted, soldered,crimped etc test the central locking using your original central locking control unit.if remote test your fob should still work without reproggrammingwrap up the loom securly as you wont need to take that bit apart again.this loom also does your electric windows if you have them.LIGHTINGfront light pins will need swopping and so do the rears the 3rd brake light pin needs to be swapped over else you will find the 3rd brake light will not work ( obvs) but also the fuse will keep popping the reverse light pin will need to be chopped and made into a double wire to use for both lights as the polo only uses one reverse light.EARTHING/REAR RE-WIRING the looms shape is diffrent to the lupo so your will need to unwrapp the whole of the rear loom to relocate the earths for the rear lighting ,fuel pump etc the roof lining needs to be removed to swop the aerial cable to the other side or can be extended with more aerial cable.ENGINE/GEARBOXextra pieces will be need to do small but important bits of the conversion the speedo sensor will need changing or chopping.fitting the engine is just the same as putting the normal one in unless it is a 1.0 ltr then you need new engine mounts and a 1.4s,sport,gti gearbox the gearbox bolts will need to be change for either gti bolts or you can chopp them to fittadvice you to do the conversion on a abs type lupo as the abs one is more just plugg in and off you go. the non abs will need you to rip the bulb out of the clocks and hide the wiring your chopp it.throttle bodie has more air pipe hole in that will need either unscrewing and blocking or tubed to one another.if you do not have air con take the pump off and the gti steering pump with it and replace with the 1.4 pump the belt you need is 11.4 s belt.as for the cooling fan your need the relay off the gti that goes in the engine bay they are also on lupo gti's connect this all up and get a garage to test it with daignostic tool everything else is the same as the 1.4 so if you know how to take it now you know how to put it back in!HEATINGthe gti heaters use electric motors and a electronic computer to adjust the heating and location of the blowing airyou can fit these in or you can simple chop the live which is the black and red large wire and solder it, female connect it to the orginal heater connector with the earth done the same aswell.everything else is a plug and play game done this so people that want to do the conversion have an idea what there getting into!

the brit Posted September 29, 2010 Report Share Posted September 29, 2010 So what is the advantage of using a Polo GTI engine instead of a Lupo GTI one?Sorry if i'm missing something obvious! Quote Link to comment Share on other sites More sharing options...
treblet Posted September 29, 2010 Report Share Posted September 29, 2010 It fits easily.The Lupo GTI engine is a pig to fit and requires a lot of new parts, the Polo GTI engine will nearly drop straight in. Quote Link to comment Share on other sites More sharing options...

treblet Posted October 5, 2010 Report Share Posted October 5, 2010 That's because you took it to some pikeys! Any progress in getting money out of them? Quote Link to comment Share on other sites More sharing options...
BaileyVW Posted October 5, 2010 Report Share Posted October 5, 2010 I Think with the right tools and all the bits you need there and then you could probably do this conversion over a weekend with two people. Hope you get yours sorted Rich nothing worse than a pikey job. Quote Link to comment Share on other sites More sharing options...

ChristopherReeve Posted April 28, 2011 Report Share Posted April 28, 2011 (edited) I have a sport, can I use my sport manifold, engine mounts, drive shafts ect? What other parts will I need apart from loom, ecu and engine? Edited April 28, 2011 by ChristopherReeve Quote Link to comment Share on other sites More sharing options...
arosabinns Posted April 28, 2011 Report Share Posted April 28, 2011 yes you can use your exhaust manifold. gearbox. driveshafts. radiator. most of your coolant piping but you need to get oil cooler linked up.you can use all the engine mounts as long as its 16v engine. you can use the flywheel clutch etc.the main things you need is complete whole car wiring loom. engine. ecu transponder box and chip. decent tools to get interior and dash out.you will need the gti intake manifold and gti airbox. there could be a few more bits.if you pm me with any questions or problems its fine, me and loopmuscle are currently in a 1.4s to gti conversion with front hubs rear beam, abs system so we will be doing everything needed with new looms the lot so just drop a pm Quote Link to comment Share on other sites More sharing options...
Tigzâ„¢ Posted April 28, 2011 Report Share Posted April 28, 2011 1.0 engine and mounts are the same for the Polo GTI conversion.Gearbox and engine mount is a direct swap on a Lupo GTI engine and gearbox. Quote Link to comment Share on other sites More sharing options...
arosabinns Posted April 28, 2011 Report Share Posted April 28, 2011 8v mounts are sat a few cm set further back, they were on my mk4 polo and the engine bays are the same Quote Link to comment Share on other sites More sharing options...
