Basically I have a standard (ish) Mk2 Golf Syncro with a 1.8 GU engine in it. What I want to do is get rid of that and put a G60 lump in it.
What I am not too sure of is what I will need, other than the enigne and wiring.
Will the standard gearbox be man enough for a G60 or do I need to upgrade my drivetrain to parts off a Rallye?
I have had a search through the forums and cant really find much about converting to a G60, but please point me in the right direction if there is a thread on here.
Any help would be much appriciated!! Thanks [

if you use a passat g60 gearbox the transfer case will have 22mm lugs in the drive flange, some GU powerd syncros have 22mm lugs on there propshafts and they will go straight on to the drive flang of a passat transfer case. i think it soposed to be year dependant so 90 speck should be 22mm pre 90 18mm ( but i have found both 18mm and 22mm lugs on pre and post 90 cars )
you can press the lugs out and make a conversion doughnut and go 18mm-22mm 22mm-25mm and even 18mm-25mm just make sure the lugs prees out square and cleanly without distorting else they won’t locate properly, then they cam out and snap the bolts and make a mess of the prop or drive flange
had it happen on mine and it was a bit of a pain to fix.
as chris said for reliablity you really need a cabel change box. i know some people who have done g60 conversions on rod change and claim to be running 200bhp reliably but that makes me think that they spend all there time polishing and don’t ever actualy drive it. most g60 conversions you see on ebay are rod boxes as well 
. i broke a pair of rod change boxes with a mildly tuned 2.0 8v couterflow the other issue with rod change is clutch life as the wheels won’t spin much the clutch tends to get more wear and if your motor is makeing good torqe if you set of in a real hurry the wheels won’t spin but the clucth will spin up go cabel change and 228mm clutch it’ll last a lot longer and won’t spin up
