Urm, I don't no much about engines either mate but as one person told me "Anything is possible with a wod of cash at hand"

I would imagin its more than possible, as we have pics floating around here with big lumps in little lupo's, is there a specific lump your reffering to or is it a general engine enquiry in which you want as much info as possible thrown at you ?? jump.gif

Yes of course it is possible, the cost may be more than you expect though.

Plenty companies could offer you the service, and I think the MK5 is easier than others before as more space. The problem I think is the wiring loom, as any splicing of wires invalidates the warrenty on anything (should you still have a warrenty). Also I note that a lot of the guys that supply the engines charge a lot more for them than you can pick them up for in scrappies, etc - so it will pay to shop around.

Ring round the scrap yards is probably your best bet - ideally you will want engine, gearbox and loom, you are quite lucky because you can get the engine from skada, seat, Audi or VW so plenty choices - obviously some have larger power output than others.

there are some companies that specialise in doing this kind of work - i cant think of any of the top of my head - Awesome perhaps, TIm Styles Racing, there will be others probably advertise in PVW or similar.

Yes it is possible to transplant a 1.8 20v turbo engine into a mk5 polo. but, there are many different type of 20v engines. some have throttle cables, some use a system call drive by wire which uses an electronic sender in the pedal. some have secondary air injection systems, some have variable valve timing. some are transverse, some are in line etc etc etc.

i would use an engine with a AGU engine code because it would be simpler to implement because it has less fancy stuff attached to it.

next you will encounter a problem with gearboxes. the gearboxs for most 20v motors employ a shaft change system. but mk5 polo has a cable change system. however a mk3 golf gti 16v has a cable change gearbox (02a gearbox code) which will actually bolt onto the 20v engine with ease...

next problem is engine mangement. all late vw's use a system where the ecu has a code which can only be activated by the correct key. this means that unlike earlier vw's u cannot just take the ecu and looms and just plug them all together. also the dashboard display/dials are linked to the ecu meaning you would need the whole rig. ecu, loom, ignition switch, keys, dials, etc etc.

this is where i would use an aftermarket ecu to control the transplanted engine. using the original dials and wiring intact. this would abviously have to be mapped on a rolling road/dyno!!!

Well it's not Peter Cooper Volkswagen if that's what you mean!!!!! they should open up a circus with all the clowns they've got working for them

a few more notes on engine transplants which i forgot to add before.

you are gonna need the charge pressure control solenoid which is mounted somwhere on the bulkhead depending on model

also an intercooler is required. for the mk5 polo it might be worth getting hold of a front mounted intercooler from a tdi polo. wink.gif

I'm a year and a half late, but I have a 1.8T AGU and i'm thinking of sticking it into a Polo (cos my car's a write off).... I guess it would be easier since i've got the whole car - will the engine fit into a Polo (dual headlamps) or am I better off trying to fit it into the new/facelifted Polo?

I think you will have a lot of problems with boardnets control, as the 1.8T engine was never fitted to a vehicle with boardnets so you will fined that all the cars control units will not talk to the Main Engine Control Units. Also the Mk 5 has gateways/can-bus systems on it which will be nothing but a headache. Read up on these systems before diving into deep coffee.gif
