stony Posted May 31, 2002 Share Posted May 31, 2002 Here is a mod i did on my rx 7 a couple of years ago... the mod was to get twin stock oil cooler oil coolers. for those of you who dont know the rx7 turbo FC3S has one of the biggest oil coolers around. first go to mazda trix and get the part number for the earls fittings they use in the braided line kit. the ones that connect to the oil cooler mazdatrix then get some braided hose , mount the oil cooler in the front somewhere and route the hoses to your engine and connect with whatever your engine uses to supply oil to oil cooler or a remote oil filter or whatever it works really good Quote Link to comment Share on other sites More sharing options...
Tony240ZT Posted May 31, 2002 Share Posted May 31, 2002 I've got one of the coolers, just trying to figure out how I should mount it on my Z. I think the majority of my problem is the way I had to tilt my IC to make it fit. If someone has pictures of the rx7 oil cooler mounted on their Z lemme see please.

Owen Posted May 31, 2002 Share Posted May 31, 2002 What year FC3S? Sounds like a good cheap mod! Owen Quote Link to comment Share on other sites More sharing options...
BLKMGK Posted June 1, 2002 Share Posted June 1, 2002 FD3s started in 93 so it will probably be just before that. Most all of the rotaries will have at least one oil cooler, FD3 R models will have two of them but I dunno' how big they are. Chances are slim of finding one of them in the junk yard anyway Quote Link to comment Share on other sites More sharing options...
stony Posted June 1, 2002 Author Share Posted June 1, 2002 any year FC3S has the oil cooler im talking about. Quote Link to comment Share on other sites More sharing options...
Guest Thurem Posted June 2, 2002 Share Posted June 2, 2002 If you guys are looking for a big oilcooler, check into the ones that are used on Suzuki GSX and GSX-R motorcycles GSX-r up to 92 and Katanas + bandits (GSX) up to present. They are about 8 by 14 inches single core, if memory serves me right. Can be had cheap at MC jy. Only ever had to replace one that was leaking from crashdamage (I'm a motorcycle mechanic.)
