Intercooler advice please.

Hey folks,

I've got a mk4 GTI golf and Ive had a frankenturbo kit sitting around for a couple of years that I want to put in soon.

First thing tho I want to put an intercooler on this weekend. The intercooler I bought at the same time as I got the FT kit is a CXracing 27x11x3 (21x11x3 core size) and it seems really huge.

this one -> CXRacing 27x11x3 Turbo INTERCOOLER For Mustang Fox Body 280Z 3" inlet & outlet | eBay

I've done some googling and can't really get a straight answer about whether its way too big for a frankenturbo'd 1.8 or whether the PSI drop will be made up by the much cooler air.

Any thoughts?

thanks

oh ill be very interested to hear about this too!
My guess is that if you get a tuneable Diverter Valve for example the forge 008 Diverter valve, you could adjust how much pressure it diverts back to the turbo and how much remains in the system?? like to preserve some pressure in the intercooler? I don't know... it boggles my mind.
you will certainly have the cold air though.

It's big but don't sweat it. The FT will cope.

hey im super keen to hear what your experience with this intercooler is, Im looking at buying an intercooler off gumtree but im not sure how to choose something suitable, being that there are none specifically 'for' my AGU.

I probably wouldn't go mad if you're keeping the std turbo. No idea what any of these are like but it will be a lot less effort to fit one over a front mount.

that sounds true enough,
Ill save fitting a fmic for when i get hungry again and upgrade the turbo to the s or 04.
I have a stealthy black silicone TIP coming as we speak

I wonder what one of those would be like on the Polo.

Nice, that puts my mind at ease gav. I'm going to put this bad boy on this weekend. I'll report back about PSI drop on the stock turbo for anyone else interested.

thanks guys.

Just installed a front mount, the biggest problem is fitment. With 3" in and out, you are going to be trimming your front bumper big time. To the point where it will look totally ruined. I fitted 2.25" piping over 2"inlet/outlet and that seemed to be the limit to be able to hide the install.
