You can use the XR3i radiator, dont worry about the waterway for the turbo.


Swap over for a S1 T3 that runs the oil cooled turbo, not water/oil cooled like the S2, get a decent intercooler (GRS or PRO Alloy)

imo the car runs cooler with out the water cooled turbo as all the turbo does is heats up the water and defeats the object

just my personal opinion


im going to be running a T34 with no water, just oil
