Hi, I'm looking for an intercooler for my rx7. I'm planning on building the car to around 300-350 whp (w/ RZ turbo). Which intercooler should do the best job. I'm pretty sure I want a SMIC. My ideal will be minimum presure drop, quick response, and minimum engine bay temperature. Please give me some input, and explain why you suggest the intercooler. Thanks.

M2 Med, because everyone uses it.

i have the greddy FMIC, put down a bit over 330rwhp with 14 lbs of boost. (110k on motor and turbos)

I havent had any trouble with heat issues or pressure drop.

2 or 3 row?

Greddy SMIC, it fits great and should be good up to 400-450whp

Just about any aftermarket intercooler will do the trick, as long as you don't go over 15 PSI. Then you will get more into the specific intercoolers.

the apexi FMIC is a nice unit and is designed for either single turbo or stock setup! It's sold with piping for stock turbos which is nice, throw that and the efini y-pipe and your good to go!

where is mahjic ?

He knows the answer to this question.

fmic is overkill for stock twins...get the m2 med..perfect setup for 350rwhp street driven FD....i am alittle biased though.

DeNguyen

how is it overkill?

dubulup

PFS SMIC is nice, get the efini Y...

matty

twins dont generate that much heat or that much psi, blocks rad, more lag...etc..
the trade off isnt great enough for me atleast.

get the Greddy 3 row!! Overkill!! You'll need to run over 15psi with this one though, correct me if i'm wrong.

and doesn't the M2 have fitting issues when you put in an aftermarket radiator? or is that just the bigger M2?

artguy

no..it doesnt...i have the mazda comp radiator and the m2 large. the m2 large is my favorite IC...its great.

you want something with the LEAST amount of pressure drop possible. the stock twins are already working overtime and if you get a good ic like the m2 then they do not have to work as hard to put boost through the system. the stock ic..if you want to run fifteen lbs...actually pushes over seventeen lbs just to get fifteen to show up because the stock ic is a POS. the fmic has pressure drop issues as well from what i understand. the m2 units have almost NO pressure drop at all and are thus the best choice among the setups.

since the m2 units are impossible to get..rotary reliability and racing has manufactured some for their shop. you should be able to get one from them if you want. I believe they are a couple hundred less than the m2 but are very similar in design and fitment.

M2 med/large

www.scuderiaciriani.com has all the info...dig around and find the intercooler section.

Since when?!?!?!?!?!!!!!! The twins run HOT ....

IC-wise, I think the M2 and Greddy units offer the best performance of what's out there.

matty

well comparatively speaking....to a t78 at 25psi

i think it depends what you want to do with the car.

a lot of dragstrip runs? the general rule of thumb is go with a front mount

track? the general rule of thumb is a stock-mount, so you won't have to worry about overheating from blocking the radiator.

The PFS in really nice because it fits well with the Efini pipe. I'd venture a statement it is the best fitting aftermarket IC for the FD.

The M2 med IC has a bigger core than the PFS, I like it alot too, but the fit could be better.

FMICs have fit issues IMHO, cutting up the front, etc isn't my idea of modding my sweet FD.

What is the difference between the M2 medium and large ICs? I notice that they are the same cost, and people often recommend them at the same time.

BenzaLee

Got the m2 large with my rx6, love it.

The M2 large is essentially just a stretched medium IC core. Essentially, the large forces you to either relocate or miniaturize your battery and then takes up the space the battery previously occupied. So you get a bigger intercooler at the expense of more effort whereas the M2 med just fits right in with the stock battery(and most aftermarket intakes).

I'll second the opinion on the M2 as I've got the medium and the fitment is fine. I think Jason has them in stock in the RX7 Store or should be able to get them.
