Does anyone make a larger oil cooler? If not are there any companies that make a cooling fan for the 8's?

are you trying to get better cooling on your oil system I suppose. If you need a bigger oil cooler, Rotary Extreme makes a set for FDs that are pretty big (actually too big in some cases). I'm pretty sure if you get creative you can mount them in. Size wise I know they will fit, if they fit in a FD's bumper they will fit in ours. Now, they are not cheap.

If you just want over all cooling upgrade, an aluminium radiator will do a great job at it as long it is thicker than the factory one.

no such thing as too big as long as you use a thermostat.

install 3nd oil cooler with thermostat. go to Summitt racing and decide which one you want. in the DIY forum there is an example.

Some people on the RX7 club reported that it was too much for the street. Temperatures would drop to much. And for track it was perfect. This is their dual set up.
here is a pic of them

Now that I think about it, how do they report that is was dropping to much on temp with a thermostat?

but any ways I think that set up will work for you.

How many row is the stand oil cooler ? Ain't the twin stock oil keeping up at the autoX/track ? Ducted ?

Thanks for the help and opinions. I'll probably look into a larger radiator first.

I had a Fluidynen my FD. I put it in due to the fact that I had a FMIC and I notice a increase in temp. Once I change that radiator it was better than before I put the FMIC. Koyo is another good one but I'm not sure if they have a application for the 8 yet.

I don't know how many row the stock one is but those ones are 34 row.

Good-Win racing sells a Koyo radiator for the 8!

Thank you for the help, and I think I just might have to go with the Koyo.

I bought my RB exhaust through them, & was pleased with the service.
