Just wanting some info on Intercooler sizing for a NA6.

Also, the fitting and placement etc. maybe even plumbing ??

Where do the factory place theirs ? And their specs ?

Thanks for your help.

Regards.

Where do the factory place theirs ?

The factory never produced an NA 1.6 turbo. In the UK the UK Mazda distributer did something similar to the Australian SP with an NA6 except that it was all done outside of Mazda and sold as a kit that could be fiited to new cars and retrofitted to used cars. I'm not sure if it even had an intercooler. Were intercoolers as popular in the early 90's as they are now?

Intercooler are best placed infront of the Radiator
As for there Size on the NA with out A/C you can fit a 650mm x350mm core in there with out to much hassle.
This is the core I put in my Old mans car



It was an Ebay jobbie and on the Dyno with 5PSI the intake temps were down around the low 20's

I have Kept the A/C but had to remake every bit of pipr work

I have a massive intercooler in my NA, with air cond. Not sure of the exact size. Basically mounted in the same place as Russellb. Not too many places to mount an intercooler in an MX-5 unless you do major mods to the front end.

There is a Vic club member (JohnD)with that kit in his Neo NA. I'm pretty sure there is no intercooler. The Melbourne based turbo shop that fitted Johns still has one of these kits for sale. $3500 for the kit + $1500 to fit it. It uses the standard ECU, with a piggy back. Nice looking kit, very well made as you would expect given it was sold in the UK with full warranty.

thats how mine was done much the same as the others
hard to really do it any other way and it still fit neatly!

I believe the BBR kit came with an intercooler, but it was a tiny jobbie (smaller than the SE's) and mounted behind the radiator...

Here's my setup:

My intercooler is 500x200x70 and sits pretty much where everyone else's does. This size slid up between the front chassis rails perfectly with a couple of millimetres each side. $240 off ebay...

What turbo are you running russellb? Because that intercooler is massive! I would expect to see it bolted up to a T78 or a T51R or suchlike. Any idea what the pressure drops for it are? By the way, like Sean said, that is the cleanest engine I've ever seen! Wish mine looked like that...

Do you other intercooled folk still run your AC?

I do

hey guys, do you reckon 550 x 140 x 65 with 2.25 inch pipes is big enough ? i won't be running massive boost, probably 7 or 8 psi max.

That'll do nicely.
