A mk3? Im selling my 1.8. I hate mk3 and everything about them lol
Read again what I wrote. Swap everything from the mk3 GTI to the mk2 1.3. the gains would be very impressive, fair enough, you dont like it, but not only does it have good reliable power, 8 or 16, but it weights about 300-400 KG more than the mk2 1.3 !!!!
If you just buy an engine you will be back and forth to the scrappy for ever, as the 1.3 has not just a differnt engine, but differnt gearbox, driveshafts, gear linkage, engine mounts, radiator, list goes on and on.
And , excuse me if im wrong, but as mentioned before, the gains of replacing your 1.3 (mine was extremmly reliable) to a FI 1.4 gt polo engine, will be 25hp !!!!!
You gain more buy removing all seats, spare wheel, sunroof, headliner, door cards, rear wiper, etc etc
