Default t88 seized t4

has my pt88 take a dive and lock up today. cold side bearing is seized up. is their any wheel thats larger than 88mm that i can get swapped in. any options to get more power out of is. its on a t4 flange.

also could a 370 spool twin 88s, its a track car?

whats a typical rebuild cost?

Sorry to make the first post a question and not an answer to any of your questions .. but is this a front mount and did you use an oil restricter?

370 is kinda small for twin 88s...

the guys at forced inductions should be able to tell you if you can swap in a larger wheel, but the t4 is probably restricting that since extra flow produces extra exhaust

i know forced inductions looked at putting bigger wheels in there, not sure if they went into production with it, dont thing the gains were that much though.

yeah i think i may just hack off the t4 flange and go with the t6. twin 88s would be sweet though, think a 410-434cu lsx could spool them

thats not low boost

why bother with twin 88s unless you are trying to run 30+ psi on a big motor?

twin 76s would be a much better fit

i already got one 88, eventually im thinking twin 88s with 25psi but i need to have a car that can support that. i think twin 88s on a 408 or so would puk 1k to the ground @ 15psi

The compressor cover on those units is already about max with an 88mm wheel and the T4 turbine housing on that turbine wheel is maxed.

Let it be known Dr. Turbo does it for $250 assuming nothing besides basic rebuild parts are messed up.
