Hi all,

It's been asked before in various threads, but I can't seem to find the info I'm after when doing a search.

So, what I want to know is, how does the Spec C TMIC compare to the 08 STi one?

If the 08 STi TMIC is better, will an 08 STi TMIC fit a GD pretty easily (assuming the clutch cylinder change and correct brackets installed)?

Cheers

08 STi GRB TMIC is bigger than the GDB Spec C TMIC and still has that divided top tank setup.

Yes a 08 STI tmic will fit in a GDB engine bay.

~4% more volume on the 08. No Sti wording sprayed on, so street cred is down 50%.

JDM Sti 08 vs 05-07:

Fantastic comparison!

I need the extra volume as I'm running a TD06. Looking at making 330-340 at the hubs on TMIC, with massive response.

Joe,

I thought that surface area would be a more important criteria for cooling? And that a larger volume would decrease the responsivenes...

As above. Go for the biggest surface area one that will fit, check the fit and sealing between the air intake and TMIC -and get the STi wording.

Absolutely, but volume comes into play when you're running 24 psi as I am..

The fact that the volume is slightly larger (and the surface area is bigger), means that the slight difference in response between the bigger 08 STi and the Spec C (negligible), will be worth the extra capacity.

don't go for surface area, you can only get so much air through the scoop, go for depth.
Process west make really good kits, comes with new splitter to fit intercooler

tube and fin for efficency and surface area.

bar and plate for heat soak and depth instead.

stick to the 08 cooler joe, you wont be disapointed.
