FYI: I found the guy you are talking about and he has a VERY old kit. He has manifolds and turbos from what appears to be the late 1980's.

Here is the quote I found at LS1tech.

The two latest style of manifolds will outflow the original not to mention the old rajay turbos are much smaller than the Garrett units currently used.


Having said that and having worked there I would have to agree with T70stang. When it comes to their diesel product they are no longer the leaders in the market, they like to follow now IMO. Most of what you see in print and in magazines from Banks is not available over the counter. The Camaro, Funny Car and sidewinder projects are built through the "Banks Race Shop" which is seperate from Gale Banks Engineering. Sure they are at the same facility and owned by Gale but the people employed in the race shop have very little to do with parts that are sold to customers. These vehicles and parts are for promotional purposes only. The only exception is the black street truck powered by the 6.0 SBC TT and even it has parts on it that aren't available with the TT kit.

I agree. Being new to the diesel owners market (bought an 07.5 LMM Duramax a couple months ago) they do not appear to be the leaders in the diesel market like they once were.
