Default Question for LJMS/Forcedinductions/anyone that can help

Hello all,

Gonna upgrade to a better turbo.

Here is a picture of the current kit that I'm running (turbotechnology race kit), with an old BorgWarner ST80/T4 turbo. It fits with slight mods to the flange to support the extra weight.

My question, does this older ST80 share the same turbine T4 housing dimension as the newer s400 series T4?

All i know is that it is a Borg Warner T4. Not sure if it is divided or undivided. Not sure of the turbine wheel inside either, i am guessing it is an 83mm. It's Mecham's old car.

Didn't Mighty Mouse has the same kit and ran 91mm T4 From FI ?

My old ST80 was 83mm turbine 1.10 A/R with race cover and it was huge undivided if I remember correctly.

He did, but he had to modify his crossover piping a lot from what I remember.

He did run the same kit, however. I just want to run a bigger turbo with this TTi race kit. Currently choking my built 370ci LS with a TC 76/68 is no fun (came with the kit)

Thanks so much for your feedback.
