I have a 1989 T2 and I want to up grade the cooling system. I was wondering If I get an aftermarket radiator wouldI be able to throw out the fan shroud assembly and the fan?
and for the FMIC, would I have to take off the A/C to make room for the FMIC?
thanks for help and suggestions.

You can only get rid of the fan shroud and fan if you are installing an E-fan. Many people have had cooling issues with electric fans, you really are better off with the clutch fan and shroud. We recommend Koyo, if you are really going to be pushing the car install the N-Flo http://banzai-racing.com/store/86-91_rx-7_radiator.html


The Greddy FMIC fits fine with the A/C, if you are making something custom, then it depends on how you route the piping. http://banzai-racing.com/store/86-91...tercooler.html

why would you want to throw those away? you seriously think the Radiator can cool itself off without a fan ?

You need to do more homework on your car.

nygcps I understand That is why I was thinking of the E-fan.
but I didnt fully understand if I kept the fan shroud.

Most Electrical fan will not be able to pull more air than stock Clutch fan. the only bad thing
about it is that its taking a lot of space. and the stock fan shroud is pretty good if u ask me.

my Ford Taurus E-fan pulls 2300cfm on low and 4500cfm on hi. works fine if you install it correctly so it works using the fan thermoswitch.

thanks for the information.
now what brands would you recommend?
I was thinking to go with a koyo racing radiator.

GOT-RTRY, no one said there were not e-fans that could out-flow the stock fan; just that most can't. Taurus fans can pull a lot of air through the radiator, but it will also take around ~33A continuously to do it (high setting). It looks like you're using a 70A S4 alternator, so that's not the best for that setup. Stepping up to a more powerful alternator is pretty critical when going with such a powerful fan. My S4 alternator was not happy trying to supply my 12A fan, let alone one that pulls 33A.

i was always a fan of fluidyne radiators i'll be buying one for mine along with a e fan setup. i'd suggest doing a FD alt upgrade or atleast a higher output one if going to a e fan setup.

Thanks.
So the T2 alt wont be as strong as the FD?

I am aware of what was said, i was just giving an example of one that could. I should have worded it better and the flag was all in good fun.

i did noticed a little power draw from the fan, its running on the low function since i don't have A/C. what's a good alternator for the setup. (I want the pineapple racing bracket)

sorry for the thread jack but its relevant right?

i always heard goood things on flex a lite fans they will be who i'll most likely go with look at link. http://www.flex-a-lite.com/auto/html/electric-fans.html but there are other companies out there that are good to. just got to look for the CFM and AMP draw on them find the best CFM and the least AMP draw you can find if worried about the alternator not charging enough. as for the T2 alt i had a s5 T2 and bought the upgrade from a forum member years back that sold FD alts to swap into s5's.

notice I said MOST I didn't say all. you know what Most/All means right ?

my point is : if your Stock Clutch fan has failed then maybe its a good time to go for E-fan.

but if the stock clutch fan works just fine @ cooling stuff down. what is the point of having the a e-fan(plus all the work) ?

Koyo is a far better radiator than Fluidyne, it is thicker, has better welds and does not use the petcock drain that always fails.

Most people that have cooling issues associated with e-fans, have FMICs or they install a fan with no shroud. We have found that our water temps climb when the A/C is on in our vert, I have contemplated installing a clutch fan and shroud. We have the largest CFM fan that will fit the FC radiator from Flex-a-lite.

hey maybe you should bother to read my second post before taking stabs at my intelligence. i agree with you. i was just posting one that would work. the flag was a joke! even though you hurt my feelings i still like your fd.

Wicked clean engine bay Banzai. Can you show what the corner notch in your efan shroud looks like to clear the upper water tube elbow.

When you say "...water temps climb when the A/C is on..." how many degrees are we talking about? over 205? 210? . I'm revamping the A/C system now and will be going w/ a FMIC (more of a middle mount actually) in the near future.

Banzai- I had a "3800" CFM fan and shroud and I was not happy with the temps, after much debate I decided to give the taurus set up a try- I have to say it just does not compare to the other one, temps never get over 200 now. It took alot for me to give the fan a try as I was putting my faith in the one I had. To be honest I dont know if its the shroud design or what but I originally had a 2800 fan and I really do not think it worked any different then the 3800

I think I am going to check out this villager fan as I hear it fits the radiator a little better

Here is a pic




I turn the A/C off when the temps reach 101C (214F), then they drop back down. I see these same temps on stock FD's with the A/C on. I just don't like seeing them that high.


I had the 2800 prior to this one and basically have come to a similar conclusion about the 3800. Again I am tempted to just put a clutch fan & shroud back in to see if all the temps stay in check. I do not have any problems with customers' cars that run FMIC's and the stock fan.

Of course keeping the A/C in the Vert is aggravating the issue, but it sure is nice on those hot days to have the top down and ice cold A/C blowing

Like to hear what you think of the Villager fan, if you try it.

fiero e-fan on mine. Never had cooling problems. Just wire it in correctly.
