Is there anything 90mm available for the trucks?I just finished installing a 408 stroker and I need a 90mm tb.

 

sure, FAST makes one, but it won't help you unless you do the manifold with it to accomodate the larger hole. i have the stock intake and TB on mine and don't have any problems. you going NA?

 

That's right you will have to use the fast setup. I am putting one on my truck but mostly for the ease of putting on a direct port nitrous system.

 

Yes the truck is NA for now. Just trying to get the most out of it.I have the ls2 90mm tb and intake from a 05 SSR. My problem is I have not figured how to wire up the tb (plugs are different)

 

What year model truck? Where are you located?

If you have an 03+ truck, maybe this will help:


The LS2 TB electrical connector is physically similar to the 03+ trucks, but the trucks have 8 pins inside while the LS2 has 6 pins.

Anybody else wonder how a 90mm TB would do on a Radix?
