heh, i also have a t-type and a GS. Kinda cool to have 2 boosted regals -- one for a race car and one for daily use. especially when they both haul! kinda sad though -- when i get everything installed, the GS will have much more money put into it in mods, yet will still be much slower than the t-type! The GS is cammed, pullied, and ported and polished with headers, PCM, lifters, valve springs, and some minor bolt ons.
The t-type will just have a bigger turbo, injectors, chip, and fuel pump!
oh, and if you are looking for a reliable daily driver, a modded DSM would not be a very good choice. yes, they can haul when modded -- in fact, are much like a turbo buick in that they can be really fast with just some minor stuff -- but they are definately not known for reliability, especially when you throw some mods into the mix.
btw, my regal GS will be for sale pretty soon -- it's a '98 maroon/grey car with 80k on it, and it definately isn't slow. i'll be looking to get about $6500 for it. u interested?
