As your going RS2 spec and your in a pretty hot country I think I'd go for at least a 13 row aftermarket cooler located in the OE position. I take it you still have the Aux rad?1990 B3 2.0 80 quattro.

A few folks on here have fitted larger oil coolers in the OE location, see if you can find a thread with a good example so you can see whats involved. If the Aux rad is done away with then that makes a better location but I'd want to keep that where you are.
My 13 row setup cost me about £130 using fancy AN fittings and braided pipe, can be done for a lot less if you not so fussed about appearance. Cheaper than a brand new OE cooler and pipes and way more efficient.1990 B3 2.0 80 quattro.
