Perhaps there is already a thread on here about this topic; I couldn't find it.

I am looking to buy a Greddy FMIC. I have a single turbo TO4Z and I have Greddy compression tube. Does anyone understand which FMIC is better?

I am not completely sure what the Greddy Website specs mean.

93-96 22R stock location 1330.00
93-96 24V for factory turbos, reloc. battery 1330.00
93-96 24V for factory turbos w/ GReddy Piping, reloc. battery 1330.00
93-96 24R for factory turbos, reloc. battery 1630.00
93-96 24R -HG for GReddy Turbo w/ piping kit, reloc. battery 1630.00
93-96 32R -HG for GReddy Turbo w/ piping kit, reloc. battery 2000.00

I'm guessing I need a 24R, but do they make a 24V for a single turbo? I don't even know what 22, 24, or 32 even means???

Every picture I click on always says "actual picture may not be shown." So that doesn't help!

Anyone have experience with these FMIC's? Also I cannot find any HP ratings on any website out there about these FMIC's.

Does "For Greddy Turbo" mean that I have to be specific when I order that I have a TO4Z and not a Greddy Turbo?

Does "With Greddy piping kit" Mean that it has the compression tube with it too???

As you can see I am quite tired of these vague websites that really don't seem to help sell their products.

So what do you guys think? What do you have? What do you recommend I do?

THANKS

$550.

its bar and plate (m spec) but many people have used this and gotten big HP numbers on stock or single turbos. Should work for what you need, and considering its less than half the cost of the other kits youre looking at, you could spend the rest of that money on alky/water/meth injection

Good info! So what did you decide on? Blitz or Greddy?

More good info! I haven't really planned on going road course with it, but it does seem that the heating issue is a big one with FMIC's. Which FMIC are you running?

Why not go with a larger stock mounted cooler. Like Pettit's for example.

I'm not using one, I'm using a SMIC. The Greddy is fine for what it is. You just need to pick the best IC for your use. The Blitz and Apexi FMIC's are a little smaller so you get more air around them to help with cooling. IMO, if you aren't drag racing, don't get a FMIC. But, that's just my opinion.

It's not just your opinion

Honestly, I don't know why anyone would get a front mount. Maybe so that others can see it???? Thats a reason, but a really bad one

The 7 is just going to be my weekend/ occasional drag race car. YES! I do like the way the FMIC looks like on the 7 and on any car for that matter, but I really like the idea of having the direct cool air in front where it should be instead of being under the hood of a hot engine bay...IMO.

i decided on using the blitz fmic... when it comes to cars especially one that im goin to keep for awhile... you get wat u pay for... so i went w/ the quality and performance .. although i have no beef against greddy

the stock mount aftermarket cost jus as much as the fmic...

Honestly, I think a lot of it also has to do with how mechanically inclined one is. I had the Greddy FMIC and I'll admit, it was a pain in the rear to install. If I could go back, and given the knowledge I've obtained now, I'd stick with a decent SMIC design.

1. Easier to install.
2. Better flow and function for the cooling system.

Just my two cents.

The actual installation doesn't bother me, I am quite mechanically inclined and do all my own work. Provided I have the right tools!

My concern now is about this cooling topic. Do any of you have electric fans to help with this issue? I do have a the aluminum 2" Koyo radiator (my 1st upgrade) shouldn't that be enough to combat a FMIC?

Your Koyo can't do squat if it's not getting enough air. Did you read the other thread? That guy also has a Koyo. Adding a larger radiator and then reducing the amount of air to it only makes for a larger heatsink. If anything, you'd want a slimmer radiator to allow the air to pass through it easier since you will have less of it with the FMIC in front.

add and undercar shield. I have a FMIC and a KOYO also, on a hot day in az, 105+ the car does on go over 100C, thats driving around town. The fan kick in way before then and it does not move up above that even if im under medium boost.

The last time I saw an RX-7 overheat from a FMIC was 4 years ago and that was at the the track. If your RX-7 is a street car and you live in a resonable climate then you wont overheat. If you do then you have other issues with the cooling system.

Yes, I did read the thread, I just forgot about all the parts he had on his car. Good points to think about though.
