TE72_Turbo, yep, that's me! Laziness and lack of funds has shelved the intercooler idea for a while. I am investigating getting a series 4 rx7 'cooler "boxed up" and turned into a water-to-air. I'd rather this setup to a front mount, as I'd prefer to keep what's under the bonnet a bit of a secret. Well, not a secret as such, just 'out of view' to Joe Public.
