m1noel Posted September 2, 2006 Share Posted September 2, 2006 I have searched this site but can't find any real input as to which radiator will do the best job cooling a v8 such as the LS2 I am about to start swapping into my 78. Who's is best? Johns? JTR? MSA? Aluminum? Brass tanks? Plastic tanks? I'm also interested in weight savings. Thanks Mike Quote Link to comment Share on other sites More sharing options...
boodlefoof Posted September 2, 2006 Share Posted September 2, 2006 Unless you want one that bolts right in, a generic fit aluminum radiator can be had fairly inexpensively and will do the job nicely. Check out www.summitracing.com. The "Be Cool" brand radiators are supposed to be very good quality. I'm running a generic fit Summit brand radiator on my '68 Camaro and it has worked fine for a couple of years now. Quote Link to comment Share on other sites More sharing options...
VinhZXT Posted September 3, 2006 Share Posted September 3, 2006 Here is the Al radiator that I used in my 77 280Z 6-568AE-BAX. This radiator has the tranny cooler builtin so it cost more. If you have an M6 you can get the same one without the tranny cooler and it will be cheaper. The measurement for this radiator is 25 3/4" X 19". Fit the 280 perfect with about 1/8 each each side to spare. Quote Link to comment Share on other sites More sharing options...
getZ Posted September 3, 2006 Share Posted September 3, 2006 There are several radiators that will work well, but that is just one part of the cooling system. The fan and shrouding play a big part in keeping the engine cool as well. I've got a massive custom Be Cool radiator in my camaro and it did a marginal job with an electric fan rated to 2300 cfm and no shroud on a hot day. I have a much smaller arizona z car radiator in my 240 with a taurus fan that's rumored to pull over 3500 cfm that does an excellent job with a condensor and tranny cooler in front of the radiator. The other day I was charging up the ac with the car idling for quite some time and the high speed part of the taurus fan kept the engine at 190 degrees. Mind you, it was about 105 degrees out that day. Quote Link to comment Share on other sites More sharing options...

gretchen/jason Posted September 3, 2006 Share Posted September 3, 2006 I tried the ford tarus 2 speed fan it didnt work with my 2 row radiator from be cool . So i ordered a 1 row from JTR and used a clutch fan best set up yet . Jason Supercharged SBC 350 78 280z Quote Link to comment Share on other sites More sharing options...
VinhZXT Posted September 4, 2006 Share Posted September 4, 2006 SummitRacing. Trust me I did a lot of searching and I came up with this. If you want more close up pictures of it let me know. I haven't run my LS1 with it much yet but I built the fan shrould for it and it shouldn't be hard at all. Let me know. Vinh Quote Link to comment Share on other sites More sharing options...
Pop N Wood Posted September 4, 2006 Share Posted September 4, 2006 The JTR radiator looks like a good solution. There are a LOT of people running those sucessfullly. Like Lason I have yet to run my motor, but I really like the look of the JTR unit. Quote Link to comment Share on other sites More sharing options...
LS1 240Z Posted September 4, 2006 Share Posted September 4, 2006 LT1 radiator Quote Link to comment Share on other sites More sharing options...
deja Posted September 4, 2006 Share Posted September 4, 2006 LT1 radiator That's my plan. Dimensions on the '94 Z28 radiator look close but I think it will work with the AC condenser and fans attached. Quote Link to comment Share on other sites More sharing options...
LS1 240Z Posted September 4, 2006 Share Posted September 4, 2006 LS1 radiator is apparently just a thinner version of the LT1 radaitor, supposedly they have the same dimensions in everything except for width. i belive it was SLP that was selling a "heavy duty LS1 radiator" that was just an LT1 radiator with some plugs lol Quote Link to comment Share on other sites More sharing options...
MikeJTR Posted September 5, 2006 Share Posted September 5, 2006 The Camaro LS1 (and LT1) radiator is too wide to fit between the stock Z frame rails. Quote Link to comment Share on other sites More sharing options...
LS1 240Z Posted September 5, 2006 Share Posted September 5, 2006 thats why you notch the frame. well worth cutting up some cheap japanese steel to use a proven and cheap radiator imo Quote Link to comment Share on other sites More sharing options...
