i saw couple guys here running jwt tt with greddy intercoolers, cant find the threads anymore. just wondering what is needed to do this intercooler conversion, there is a pipe that runs to the middle of the jwt intercooler, wondering where does that go once you change it to greddy, please provide info thanks

let me make a diagram, because I'm under the impression you are missing a key component to this....
greddy fmic (I=intake piping connected to plenum)
..._____________
>|____________|
>|____________>I
JWT TWIN FMIC
**________****_________
>|_______|> I<|________|<
the arrows represent the intake charge from the turbos
Basically the greddy is one i/c with two entrances, one exit to the intake mani, and the jwt is two individual intercoolers meeting together ala y pipe to go into the intake manifold.
This is one of the reasons (besides water cooling, and low end torque) I think the jwt kit is a better track kit....
Maybe this helped? But for the most part I think you would have to do full custom intake piping off the turbos. IMO if you are going to do that much work to get the FMIC to fit, you might as well buy a cheaper I/C. But don't fear FMIC piping, its a lot easier than it seems.

Reason: added the stars to line up my uber diagram

thanks alot for you explaintion. helps alot. that diagram is great for me to understand now.
XKR did run the JWT with Greddy. Forged has done it a few times, Sharif said the JWT piping can be modified to work with the Greddy IC. It is supposed to be very good for helping prevent heat soak on track days as well as less restriction when making big power. Look at XKRs build in the shop builds section the pictures below are not XKR but another Forged customer.

We have found that after about 500whp or so, the JWT intercooler setup is too restrictive to continue making good efficient power. Moving to the large core Greddy intercooler gives us all the overhead we need.

so the idea is that a thicker core is more resistant to heat soak im taking it? Seems logical, but I dont have the $ to worry about that
nice pickup on that though, i now remember seeing this on XKR's build thread
anyone running jwt tt with greddy intercooler?
