I'm thinking of turbocharging my 1.2l mk4f polo and was wondering if anyone else has done this what kit they used and if they have any pointers. Would also like to know if I will have to upgrade anything else for it to work properly.

Had my car in at the local VW specialist today, as I'd noticed a strange noise coming from the engine bay. (Comes on after about 2500 rpm when the engine is under load) He called me this afternoon to say he's almost 100% positive it's a turbo issue - thinks there's too much play with the spindle Now for the fun bit - warranty ran out in early July so unless I can get some kind of goodwill from VW I'm potentially looking at a bill for almost 2 grand! Going in for inspection at dealer Thursday morning so will at least have a second opinion, but after just over 40,500 miles, sticking to service schedules, not taking it over 4000 rpm until fully warmed up & feeding it nothing but V-Power since new I'm feeling a bit wounded. Anyone else had a similar issue with the 1.8 TSI? Or any advice on getting some goodwill from VW? i heard that shortly after mine was built they revised the turbo design, so maybe that's an angle worth pursuing

Hello Polo people what engines have people seen turboed, I know loads of people do the g40/PY turbo, iv seen AAV turbos and some GTs, even a 1L turbo but have people done 1.4 AFH turbo or 1.6 16v AVY turbo? Just general discussion about what can be done really feel like making something stupid in the future.

I have a polo 1.4 9n3 16v. I am wondering if anyone knows how easy or hard it is to fit a turbo to my car. Obviously I wouldn’t be installing anything to crazy just a small turbo to boost my car. I have seen people saying this isn’t good for the car but surely a small turbo with all the correct additionals needed wouldn’t cause any major problems?

Jumping straight in.. I need help on what sort of injectors would fit, ive heard that the 130pd injectors fit but not quiet sure on what engine code I should be looking for. turbo is not a big issue as ive heard the garrett they put on the 1.4tdi BNM was half decent, im only looking in the 100-120 range of BHP. So, a remap is definiately happening with all of the exhaust being gutted, now would a straight pipe be better than cutting out the inside of the cat? due to pressure loss or something? maybe not enough to even feel a difference but maybe. just need a little direction as this is the first diesel ive tackled. thanks in advance 🙂 Aaron.

I have for a while, I have thought about turbo cooling, and some time a go, I asked another member how they cooled their turbos that have water cooling provision. So what I decided to do is to have it's own pumped circuit through the header tank with a thermostat that opens when the water gets to 70 degrees. The thermostat will open a branch off the turbo cooling circuit into the main radiator with a non return valve. Of course what I don't know is whether the pressure in the turbo cooling circuit will be high enough to overcome the pressure in the car's normal engine cooling system. The non return valve will stop any reverse flow of engine cooling water into the turbo cooling circuit.

I have a 1.0 mk2f coupe and im looking to do bit of researchin into supercharing it or jammin a turbo on id go for a 1.3 engine first but i cant source one in northern ireland. Any help would be appreciated. Thanks

Hi all! im in the process of turbocharging my stock 1045cc motor ?? no judging....it was a free car and doing it for a bet with a jap driving mate lol need a short manifold for the exhaust that doesn’t go into a collector under the engine like the normal manifold, as I need to mount a flange on it in front of the block to bolt the turbo to. Done some googling and drawn a blank so does anyone know if there is anything in the VW parts bin from other models/marques that will mount up and do the job? come across a few mk3 1.3 golf ones that are the right type but not sure if the studs etc will work. want to avoid having one custom made if poss....trying to keep the whole build to under a grand ?

Hi everyone I drive a Polo GTI 9n3 1.8T and it seems to be really pokey when it's cold and then this seems to wear off when it's warmed up and just feels like it pulls way less between 3000-5000 revs :/ anyone else had this problem or have any idea what it might be? No lights on the dash and all seems to be in order as far as I know. All help would be much appreciated!

hi all, just my polo here had previously owned a polo CL coupe, and a genneis G40, but the G has rotten to heaven :( so i had to buy another chassis, so in this case i seen this, a stock polo fox, for 150 euro's. great, some rust but it wasnt a problem, 90% less rust then the G, just swapped all the g40 goodies in to it, and a build engine. specs : k03 turbo 3f inlet manifold catcams 286 cam thin headgasket dewedged throttle body supersprint exhoust (63mm) innovate wideband lamda running on 1.4 bar. no problems at all,custom map. street tuned
