mellonman Posted August 2, 2019 Share Posted August 2, 2019 N/A are not as thick as the TT and the auto version has a built in oil cooler for the transmission. So none of them share a raditor Link to comment Share on other sites More sharing options...
evinX Posted August 2, 2019 Author Share Posted August 2, 2019 But could you fit a TT auto radiator to a NA auto, will the shroud and rad iteself fit? Link to comment Share on other sites More sharing options...
Ric Posted August 2, 2019 Share Posted August 2, 2019 No, the fan and water pump housing is different. As i remember the NA fan would hit a TT shroud and rad. Link to comment Share on other sites More sharing options...
samdale Posted August 2, 2019 Share Posted August 2, 2019 Can anyone tell me which models radiators are interchangeable? TT AUTO NA AUTO TT MANUAL NA MANUAL Cheers Sadly it's not even as simple as that. There are thin and thick core TT rads. Seems very hit and miss with what car had what fitted. Several different fan shroud fixing layouts too. I emailed Chris Wilson about it a while ago when sourcing a replacement for mine. He had some diagrams for fixing point layouts and even when I told him I had a thin core TT rad, there were still a couple of options Link to comment Share on other sites More sharing options...
evinX Posted August 2, 2019 Author Share Posted August 2, 2019 Im thinking thick core TT rad with the NA shroud. All this is info i want to store Link to comment Share on other sites More sharing options...
mellonman Posted August 2, 2019 Share Posted August 2, 2019 The fixing points on the rad and shroud are also different . But can be made to work Link to comment Share on other sites More sharing options...
Noz Posted August 2, 2019 Share Posted August 2, 2019 Just get a thick NA radiator. I got a Koyo from whifbitz. Enormous compared to NA rad. I have a manual. I wouldn't faff about using a TT rad. There is no point mate. Link to comment Share on other sites More sharing options...
evinX Posted August 2, 2019 Author Share Posted August 2, 2019 But there is only 1 part number for the NA auto and as far as im aware the NA auto rads are thick core and the NA manual are thin core. Now i see a few auto supra rads..thick core listed with the NA and TT auto part numbers and not manual. So in theory both NA and TT auto fan shrouds must bolt on the same locations?
