Thread: Twisted Motion GT2871R Reviews

Actual Owner review here,

I have had the TM GT2871R on my B14 Avenir DET Swap for 2 years now, ever since the stock one blew up @16psi. The only problem ive had is waste gate set to 7psi instead of 14psi. i started at 14psi late 2017, stock motor all supporting mods but never dynod.

Early 2018 i was @24psi ran like that for a while untill i broke a rocker arm slapping up an automatic FBO 2017 Camaro SS. I Blew the rocker arm redlining 4th @ about 140mph, then Drove.home. fixed the rocker arm added mods to rev to 9k, and dropped the psi to 20lbs.

Dynod finally 2019 car made 418whp on e85 @20psi. As soon as i buy a better wastegate I'm going for 28-30Psi. I have never met anyone who has had issues with this turbo, its always a friend, or someone they know. I hope this helps someone make an informed decision.

(Sidenote)
I have broken more transmission's than turbo or engine. Fwd Sr20det is bulletproof, and the TM turbo is more than some of you deserve lol.

Why the need for a better wastegate before turning up the boost?

It seems to be stuck @20psi when i had it @24before i rebuilt the head, i never changed the boost input. So if I'm going to take the turbo off I'd like to put a new wastegate. Literally my only complaint. So if you buy one just add a Kamigawa, Turbosmart, Ext Adjustable internal wastegate or weld the flap and add an external.
