Looking at replacing my radiator.. I noticed the 86-88 have a different part number than the 89-91? I thought they were the same? Anyone know what the difference is?



Or should I just put a SB Chevy Radiator in it? Not sure if people do that.

the s5 has a long filler neck the s4 does not.

or for around 300 to 350 you can put a very nice koyo radiator in your car. i got one and love it.

Yes that is what I was looking at. So to E-bay or not... Know of a better price? Looks like $269 is the best price for the S4 model. I'm going to switch to an electric fan, so I can get a FMIC in there somewhere.

radiator is pretty much a radiator just measure yours (or what you've got space for) and get something that size.



double pass is good, but prolly overkill

Yeah I have 23 x 19 to deal with. A Summit SB Chevy fits, About $170 but It's a crossflow and I'm pretty sure the inlet and outlet are the wrong size. So a few $$$ to change out those for something the same size, then deal with the outlets in the wrong place, I might as well pay $270 for a RX7 unit.
