As I am away overseas working and not able to measure things up myself, I'm hoping someone out there can help with sizes for front mount intercoolers we can run, without having to cut the OEM bumper?
Majority of setups I've seen and myosin included have needed a after market bumper or cutting up the factory bumper to some degree.
If anyone out there can help with some dimensions so I can order a replacement, that'd be great...
Air to water was my next option, but I bought one of the v-mount's from the group buy but it is taking a bit longer than expected....so wanted to get something in the mean time but want to avoid using an after market bumper.
If you can change the end takes, then you have many, many options on core size.
For example, here's the intercooler on my RX-7:
Cut off the existing end tanks fabbed up a custom set to bring the pipes through the rad supports.
The core is about 14 x 20 x 3.
It fits between the bumper support and rad. Zero cutting of the support or the bumper skin.
Test fitting it with the stock tanks before modding them:
Please excuse the horrific first fitment modification of the end tanks. Was done on a TIG with a malfunctioning HF so I was essentially welding on mostly DC.
The pipes pass through holes cut in the rad supports:
Now note, this car never had A/C so I'm not sure how the A/C condenser would fit into this equation. But it shows a largish core can be installed without removing the bumper support, hacking up the bumper, hacking up the car, or a million miles of piping. Stock undertray fits with some minor trimming to clear the cooler brackets. No cooling issues at all.
some people mount them in front of the radiator, or you can find an old school Greddy kit
well you have to make some alterations up front but the actual bumper and front support beam wont need cutting. The areas I had to cut (as per instructions) is right next to the radiator support beam which is right next to where the air cleaner sits. I took the time last summer to set up this exact kit with the turbo facing downward and all so I can provide pictures if you want?

i used some ebay kit i got off some guy on the forums. i removed the factory bumper, grinded off some extra sheet metal from the mount that hold the relays, pushed it up as much as i could, i had to cut holes in behind the head lights for piping (not a thing to try after 10h of work and at 12am)
then build a 1x1 square tube bumper to stop gramma from baking into my FMIC as she pulls her 50foot boat out of her 2 parking spots lol
see pics
only problem i find is its pushed up a tad more then i would have like to see it. might effect my intake temp some once im hitting high boost il have to see, i could do a water to FMIC injector if need later, i still used the bake air ducts i had to cut them to allow for piping. the bumper is raised by 1/4" but you can tell from the out side. i was looking to keep mine looking stock aside from the 3" crock sport exhaust and rims. she a tight fit i cant remember the dimensions but looks like this ebay kit Fmic Front Mount Intercooler Kit RX7 FC3S 13B Single Turbo 300 700HP 86 91 BK | eBay
Edit: o yes looking at pic, i had to bend the fender front braces up and flatten them, as a refrigeration tech, id love to build a cooler using refrigerant and the stock a/c...
i have an HKS S type intercooler, which was introduced about the same time as the current GReddy kit. its a similar core size to the GReddy, but it sits behind the factory bumper support. it also lets you keep the S5 foglights, and the ac/ps/airpump.
the reason we've never heard of it, is because it was more expensive, so everyone bought the greddy and had to hack their cars up

interesting both pipes do not travel along the drivers side- then again the battery has been removed as well
Well, this has given me a few options, I just need to hunt around for one of these old intercoolers...what sort of power have you guys got the Greedy or HKS supporting?
It is no problem for the battery, it is already in the boot for me.
your sig says 400hp with a break in tune, I always felt those smaller old school IC were good up to 400hp, but it also depends what you are doing with it

the GReddy kit requires you to hack the whole car up. the HKS kit, doesn't, and it costed more, so its very very rare. the yellow FEED FC is the only car, besides mine i can find with that kit. i think they claim 470ps, but its probably flywheel.
if you're shooting for more than 400hp, the JDM shops tend to go with something bigger, look at the supernow car

I ALMOST purchased one years ago, but I thought $1400 was a little steep, but now I realize it was pretty bitchin for the time and place.
Thats right, the car is making 392RWHP with a big front mount but as I said at the start, I want to go back to the OEM bumpber as the one I'm running doesn't have very good ground clearance and my driveway is a right pain...in the bumper!
I thought if I could get away with a slightly smaller core until my v-mount kit arrives then I could go back to the OEM bumper...but maybe I just suck it up and stay with what I've got.
