Intercooler size question
 

With my BorgWarner s360 turning up in the next few days ive been looking at fmic's

Abit limited as to whats on sale over in the U.K. Can get the standard ebay one. 3" core and 2.75" inlet and outlet. MAZDA RX7 RX-7 FD3S 92-02 FRONT MOUNT INTERCOOLER FMIC KIT BRAND NEW | eBay

Seen a few people say that these start to choke about 400bhp and as im hoping for between 4-450 will it cope? Other choice is get a 4" core with 3" inlet and outlet and try and get it to fit. Mishimoto R-Line Universal Alloy Intercooler - Silver | eBay I don't mind custom fabing the pipework up but how easy is it to fit the universal style as most have the outlets coming out the back. Anyone got any pics?

Cheers for the help guys

Before anyone says it I want to go front mount not vmount :)

Check out the rx7store.net
They seem to have a replica greddy front mount.. Looks good!! That's what am thinking of getting

Check this link out: How much will different sized intercooler piping flow? | DSMtuners

Figure the max CFM you'll be pushing with your turbo(not what the turbo is capable of doing but the max PSI levels you intend to run) then cross reference on piping size/flow chart.

GL!
