I was curious if anyone runs a to4e 50 trim.
I recently did a turbo swap on my 07 lsj.

The kit i bought came with a 50 trim, .63 hot side.
I know this turbo is supposed to be a little laggy compared to the .43 hot side 50 trim,
but i feel like i dont have much boost/power low rpm. Low end torque feels bad!

At 4k, it boosts to about 9psi
by 5k, right below 19 where it dumps.

Does this seem right? Any input would be appreciated.

-2.5" exhaust (i know, small)

how long does the compressor keep spinning for after the engine is shut down?

i944scania

I can slightly hear it slow down for maybe 3 seconds max, after I shut it off

Also, almost no shaft play

did you put the little sealing ring in when you put the wastegate on?

i944scania

Yes. When I first built it, I put the ring in backwards. So it dumped all the time.
I mean it builds a lot of power once it spools. The low end boost/torque is just trash

is it a turbonetics? you really need a name brand high quality turbo to get good spool out of it
