welp i had my turbo modified to a t33c turbo about 3 months ago
i went through Limit Engineering in Arizona
reasearch there name in the forum or look up there telephone under vendors on
www.gnttpe.org
Ask for John Craig
alot of people upgrade to this turbo, i think they are very popular among the turbo buick community
advantages = blows 700 cfm compared to the 350 cfm stocker
works well with the stock torque converter
uses all your stock hardware and accesories, no need to cut or modify anything !!!
gives you roughly 35-50 HP more
probally would have your turbo back in a week and a half, maybe less,
the only disadvantage is it'd probli set you back about $750 dollars
well i am not saying these are the only guys out there , but they do awesome work and that turbo impressed me
i think i do have some pics of mine when it came back
ill send ya 1 or 2 if your curious
lemme know
