What turbo do you have?

[stocksy]

standard, but i was just curious, as i am lookin at getting the standard turbo customised...

Probably could clip the turbine wheel to have similar effect...

Then again whats the VG30 housing all about again? Cbf seaching..

Increasing the A/R size will give you a better mid to top end....depending on how far you go.

I'm pretty sure the rear housing standard is 0.63...not 0.64.

The most you will be able to "customise" from a standard turbo will be the highflow option which will mean a t3 shaft milled down with 360 degree thrust, steel wheel, machined housings to suit larger diameter wheels and "crop" the rear wheel to allow better flow. This will bring the boost on a little later but will much improve your mid to top end.

If you have a series 2 R32 or higher then the standard turbo will be a ball bearing one in which case forget the 360 degree thrust mumbo.

I do the highflows for $1750 on the RB's.

Hi flowing the standard turbo is the go, but shop around for pricing. Can get both ball bearing and bush bearing combos too. GCG do both, also Turbologic, pretty sure for around $1700 for BB & $1350 for bush.

You'll probably find they are about $1850-$1900 for the BB and $1500-$1600 for Journal bearing. They were last month anyway.
