I have a TB-20 Turbo from TEC. It works well for me but I have wondered what the specs on this Turbo are for a long time. I have researched on and off but cant find any specific info. I know there are plenty of people using them. I know LC engineering used to sell a version of the kit. there is even a magazine article on the kit. and TEC still sells the kit stating that its a custom Garrett/airesearch Turbo. I have emailed and phoned TEC and LC engineering and got nothing! I would like to know the compressor and turbine A/R ratios and trim. and any other info that's available. Any help here would be appreciated. Yes I have posted at 22rte trucks. Any help would be great!!

 

i have the same turbo on my truck and would love to know the answer as well.

i also have phoned and emailed. and they really suck at responding (its been 2 months, still no word back)

heres a link to the company.turbo.
