Also, who built your intercoolers? WHere did you get them installed? Do you guys think that you'll be increasing the size of them later on?

How much do they flow?

It is the best design for flow in a FMIC. Def. a noticible difference on lag, and between shifts. They are Racetec/SPP Z-Flo units, bought from Supreme Power Parts. I have to increase the size of mine, this one is probably going to be for sale in the near future, as I am going the Sportec tuning route and I need a much larger core area to handle what I am going to have done.. IMO, the perfect intercooler for KO4/T28/STG3 upgrades.

is it still going to be top to bottom?

i'd love to get a new intercooler....and GT30R...and rs2em, and 7a camshaft, and injectors...and DSY 6-speed...and 996TTs...

I dream big.

Very similar to the one on their 1.8 challenge car.
