What are you guys using in the way of aftermarket radiators? I looked on Racing Beat's site and was surprised that they did not offer anything in the way of radiators or fan upgrades.



If I change out the radiator on my 1985 GSL-SE I would not mind going to a larger unit. This said, it looks as if I would almost have to go to an electronic fan with clearance issues between the stock fan.



So, my questions are as follows:



1.) What type of radiators are you using and by whom?

2.) What type of electronic fan are you using and by whom?

3.) How is the electronic fan wired so as to come on at a given temperature but not stay on all the time?

4.) Anything else that comes to mind with regards to this stuff?



Thanks

 

ive never needed a larger radiator than the gsl-se one,



in japan they put fc radiators in, with electric fans

 

First off, the stock GSLSE radiator is absolutly fine.



Electric fan:

This is what you want.

Flex-a-Lite Model #155 (Black Magic Fan)

$185.95

Raason:

The Victoria British fan is crap. Pulling fans from other cars is a major waste of time and will not cool a rotary. Plus, the FXL#155 fan pulls more cfm than any other fan, even the dual fans.



If you really wanna get serious, I would also recommend an DaviesCraig EWP (electric water pump) with controller.

I contacted DaviesCraig for info on these specific to rotary applications and was convinced. I'm getting one of these in a few weeks.



There are 3 major distributors in the US.

The fan has a thermostat which tells it to turn on and off with temperature. It doesn't put a huge load on the alternator anyway.



The thermostat is easy to adjust. You just crank it all the way up, started the engine and let it get to normal operating temp (about 1/4 on the gauge) and then turned the thermostat down until the fan kicks in.



One way to wire it is:

You have one wire that goes to a switched, low-amp power source (something that the ignition switch turns on) to tell the fan when the car is running.

This will keep the fan from kicking on when you're away from the car. If you want the fan to function when you are away from the car, just hook the lead up to a source that is always hot.

The second wire goes to a high-amp, non-switched power source, this is where the fan gets its power. You can also run it to directly to the alternator.

Make sure you use the included breaker and mount it on the inside of the driver's side fender for extra safety.

A third wire goes to a ground, and if you want, the fourth wire can splice into the A/C wire so that the fan will kick in whenever the A/C is in use (to pull air through the A/C condenser).

You can also hook up a manual switch if you desire, but it is not needed and can lead to "whoops, I drained my battery cos I forgot to turn off my fan".

 

i think Fluidyne makes an aluminum radiator, with greater capacity, for the Gen II cars. you could look into getting one of those for your SE and doing whatever modifications necessary, based on fitting a stock Gen II rad into a Gen I car, I don't see why it would be rocket science - but i don't know.



as far as the best vendor for them, i don't know where you'd get the best price.
