BIGJIM Posted June 24, 2005 Share Posted June 24, 2005 My question is, can i use a new 280zx turbo rad with my small block chevy conversion? It would be a 3 or 4 row rad so i cant see why it wouldnt work well, its about the same size as the nova radiator that jtr recommends. I would be running an eletric fan with it as well. Thanks for any info. Quote Link to comment Share on other sites More sharing options...
Guest 305240 Posted June 24, 2005 Share Posted June 24, 2005 I'm running a stock 280Z rad with a stock 280Z shroud. I have a Taurus two speed fan setting inside the shroud. I had to trip the Taurus fan shroud down so it would fit, then I bolted it to the shroud. This way, all the air being drawn by the fan goes thru the whole rad, not just parts of it. I'm running a mild 5.0 and not having any problems. Quote Link to comment Share on other sites More sharing options...
MikeJTR Posted June 24, 2005 Share Posted June 24, 2005 JTR no longer recommends the Nova radiator. Sounds like you have old information. See the attached link for the new recommendations: http://www.jagsthatrun.com/V8-chapters/V8-DatsunZ-Cooling-System.pdf Quote Link to comment Share on other sites More sharing options...
A. G. Olphart Posted June 25, 2005 Share Posted June 25, 2005 Thanks Mike... When my aluminum racing radiator breaks I'll give you a call. Quote Link to comment Share on other sites More sharing options...
280zwitha383 Posted June 26, 2005 Share Posted June 26, 2005 Right now I am running a new ZX radiator with my 383 and it is not cooling sufficiently. I am running some version of the Taurus fan but it's not one of the bigger ones (it measures about 13" in diameter). On cool nights I can level off at say 235 degrees which I know is not desireable. I am however running a fairly wild 383 with the stock oil pan. If you read Grumpy's post about cooling he recommends a higher volume oil pan since oil also cools an engine. I have noticed that with my hood off I have significantly less to no cooling problems. I think a bigger fan may be in order for me before I can definitively say no to the ZX radiator for your sbc conversion. I would try it since you have it and see. With a bigger fan and a milder engine I think you might do fine and I have heard of other people doing it. Quote Link to comment Share on other sites More sharing options...
hanomon Posted June 26, 2005 Share Posted June 26, 2005 Venting the hood will also help let off some heat. Quote Link to comment Share on other sites More sharing options...
