I read about someone putting one in thier car, so I said what the hell since the koyo got hacked beyond repair. Tested fitted it the other day to see if it would fit and behold, similar dimensions. It seems I may have to get a longer top coolant hose (I used my old chasis while my other is the the shop getting the intercoller put in), fab some top mounting brackets and reloctate the bottom mounting brackets and voila a plethora of aftermaket radiators available for $200-$300 on EBAY as opposed to $400-$500 elsewhere.

Does it have the coolers for the transmission?

Not the one I have, the koyo unit may have it. Either way you can buy a B&M tranny cooler and your still total cost will still come out cheaper than getting a MK3 Koyo radiator.

heh always wanted to do that ;)

I don't have a digital camera :(
but......here is the package I got http://cgi.ebay.com/ebaymotors/ws/e...m=260015827415&ih=016&sspagename=STRK:MEWN:IT
The overflow tank is awesome, it a cylinder style and was painted red and happened to match the supras burgandy and its going to go perfect with the Ron R. FFIM. It also came w/ a catch can, but it looks cheap but ill try it for a week to see how it works out. After I get going ill let you guys know how its working out.

The S14 radiators will fit in the MKIII with a little modification. I am in the process of putting a Koyo S14 radiator in right now. The bottom mounting brackets fit the stock location, however it pushes it closer to the battery than the stock radiator. You must fab new top mounting brackets and switch the thermostat housing around. Other than those two issues, the S14 radiator will fit almost perfectly. Plus, getting a Koyo radiator for $250 as oppossed to $425 for the MKIII, the few minor modifications are well worth the time and effort.

Has eneyone noticed that the upper hose is on the wrong side of the Radiator in the e-bay pic???? You could still use it tho. You would need a longer hose.


Unless the side there showing is the side facing the motor!!!

I was thinking that in the e-bay pic its pointing like thats the front of the radiator but it isn't because the radiator would be backworeds!!! I got the hole switching the thermostat housing around I just didn't look at the pic that well. My bad
