RJansen658 Posted September 23, 2006 Report Share Posted September 23, 2006 What would be the best radiator for the swap guys? So far, I have found the standard 3.1L Lumina radiator for 3 spd trans, the standard 3.1L Lumina radiator for 4 spd trans, and the 3.4L Lumina radiator. I am wondering if there is mch of a difference, or if perhaps the 3.4L radiator is better. GM doesnt really give me too much technical specs on the radiators, anyone have any direct knowledge of differences? Quote Link to comment Share on other sites More sharing options...

(avoid the 3 speed one!) Quote Link to comment Share on other sites More sharing options...
jdcutty Posted September 23, 2006 Report Share Posted September 23, 2006 If that was the only three choices that I had, I would go with the 3.4 radiator. Otherwise try to find one out of a L36 or L67 car. Quote Link to comment Share on other sites More sharing options...
timg Posted September 27, 2006 Report Share Posted September 27, 2006 IIRC, the LQ1 had a 1 3/8" radiator with built in transmission cooler, the L67 was 1", and the L36 was 5/8" thick. Tim Quote Link to comment Share on other sites More sharing options...
RJansen658 Posted September 27, 2006 Author Report Share Posted September 27, 2006 Good Info!! I know I can use a Z34 LQ1 radiator, no problems, but since the 1st gen Luminas didn't come L67 powered, will an L67 radiator even mount into the core support? Currently I am looking for aftermarket options.... but full aluminum radiators are VERY pricey.... 90sEraWhips 1 Quote Link to comment Share on other sites More sharing options...
J Posted September 27, 2006 Report Share Posted September 27, 2006 they don't ahve to be, the local shop makes them for our shop http://www.manciniracing.com and we get them for a few hundred bucks and sell them for about $400-600. I'd look into that! Quote Link to comment Share on other sites More sharing options...
