Appreciate your help concerning the cooling on an imported twin turbo, manual. Hoping to go to Stage 3+ and wondering if I should be thinking about Oil & Water cooling? I know the UK/European cars have larger/additional rads for keeping the engine cool (and a rad on the diff).

What are the views on this and any recommendations.

Thanks, Geoff

Geoff, looking at something similar me self in a couple of months, i'll be getting a new rad fabricated in alloy but 1 more core thicker and uprate the oil cooler that sits in front of the rad, if you havn't done so already uprated intercoolers are a must at that stage, again i'm having some fabricated to suit, guy i'll be using makes these things all day every day, he uses WRC cores in his intercoolers and to any spec, if your not in any hurry, will let you know how i get on, oh and Zeds that were made for Germany had thicker rads in, smithy

Stage 3+ a bit, the cooling is fine.

 

I added intercoolers with the 555cc injectors/Dual pop as I'm putting a lot through the turbos now.

 

Now I'm running 19psi with no cooling problems. I think the stock rad is good enough unless you are going to race the thing and go mad on turbos etc. My temp always runs as it did stock (not tried this on a track)

 

BTW.. if you have a UK car, the oil cooler is bigger than the US and Jap one.

THere's no real need for a larger radiator, intercooler, or oil cooler until you swap out the T22 stock turbos for larger units. The stock pieces are sufficient, but, larger units won't hurt you since having cooler oil, water/coolant, cooler intake charge is always a benefit for longevity.
