not an easy job...and it is a heavier engine...but it is definately worth a go imo, the 4motion will sort out the handling to some extent
all the people saying "oh a tuned 1.8T is quicker, its pointless"..er...it certainly isnt pointless!
the fact is over 300bhp on a FWD car is pretty much pointless
save your money dump the r32 in, then get it turbocharged when you can afford it...if you really went for it you could see serious speeds ...see this video:
0-60 in 2.88 secs...in a golf.....imagine that in the
ibiza chassis (same chassis as a mk5 polo!)
