Turbo Sizing Question

[HotRodV6]

Ok, i have a question on the size of a turbo, im looking at gettinga new turbo for my Ty, and a friend of mine has a rebuilt Banks turbo that is a T04B and is one of the turbo they use on there newer twin turbo small block engines, with 2 of these the engine make make around 1200 horse and one turbo can support up to around 700 horse.

He said it has a TDO6H turbine wheel in a 1.00 a/r housing and a 25G compressor side, and its oil cooled only and im not sure what type of hookup it has for the DP, but im guessing either a 4 bolt flange or a v-band.

Anyways, can somebody tell me if this is too much turbo for a slightly built motor, with forged TRW slugs, comp 422 cam, stock vortecs, 2800 stall, and a fully custom intake setup that can flow like the wind, and im doing my own tuning using tunerpro r/t and an autoprom.

Also, what size PTE turbo would be a close comparison in size to this one?

Thanks for the help on this one.

Re: Turbo Sizing Question

So this is a Garrett centre section turbo with Mitsu compressor and exhaust turbines, as well as a typhoon-flanged turbine housing?

Re: Turbo Sizing Question

its all experience when it comes to hybrids... (the turbo combo you have mentioned)
with standard spec'd compressors ... the maps tell part of the story.
exhaust side tuning is a little more forgiving.... and again experience is best
Reading books like Maximum Boost or Forced Induction Performance Tuning
will explain why its so critical to get it right and help diagnose the problems.

You should set out your expectations and build to meet them rather than just
bolting on bigger parts. There are enough builds on this board to give you a
proven setup and then the tune to bring it all together.
