ok guys,
has anyone ever had their CT-26 upgraded by Turbo Dynamics (http://www.turbodynamics.co.uk)
they seem to have a very promising stage 1 and stage 2 setup spec (MD117 and MD228 respectively)
....so, does anyone have anything to say about either...or any other advice for upgrading the stage on
our turbos?

I've heard a lot of great stuff about the CT27, from ATS Racing, also some not so amazing things, but more good than bad. They have CT26 upgrades as well, but I don't know that they're worth much, to be honest. Check their site out, they've got tons of 3SGTE stuff.

the major restriction is the exhaust housing on the ct-26. so unless whoever is working on your turbo is going to do somthing with that, all its gonna do is add a little bit of power, and a bunch of lag.
the ATS ct-27 has a 46 trim to4E compressor wheel, and they machine out the exhaust housing for more flow.
i made 307whp with the '27 at 19.5psi, 350whp has been made with race gas and 24+lbs of boost.
