Kclank Posted February 10, 2020 Share Posted February 10, 2020 (edited) As noted in title. I am doing a 2006 GTO LS2 engine and 4l60E auto trans into a 1973 S30. Engine has no internal mods, will use only the alternator for external accessories. No smog, headers thru Johs Cars in Dallas, Tx. Looking for recommendation for radiator and tranny cooler. Will be selling the RB25DET motor and 5 speed manual. Leg problems limiting extended clutch use.

jhm Posted February 11, 2020 Share Posted February 11, 2020 B&M stacked plate cooler for trans or engine oil cooler. Have had them on my last three cars. Very rugged, well-built and efficient coolers. Quote Link to comment Share on other sites More sharing options...
260DET Posted February 14, 2020 Share Posted February 14, 2020 Any problem with the RB25's radiator? Are hose sizes a problem? Because any 3 core aluminium radiator that fits will be sufficient cooling wise. Quote Link to comment Share on other sites More sharing options...
Kclank Posted February 14, 2020 Author Share Posted February 14, 2020 Existing radiator was a 2 core , replacement found is a 4 core with larger inlet/outlet tubes. Thanks all for suggestions.. Quote Link to comment Share on other sites More sharing options...
