Turbo size ? for a crawler motor

[tarussell]

I am in need of schooling on housing size and when it is too small for a motor.
My application is a 6BT that came with a 16cm housing and I want to go as small as I can without crossing the safety/durrability line for the motor.
This motor is going in my Blazer as a crawler motor so I do not need to worry about on the road situations like pulling grades or sustained high RPM's .
I just want to make this engine pull as hard as I can at very low RPM's and from what I have found the smaller the housing the more low speed driveability it will have due to the boost coming on stronger at a lower RPM.
My question is what is too small and can I use a 12cm housing safely with a 6BT motor???

I am hoping that the proper size housing for my application along with injector pump adjustments this motor will pull extremely hard at idle and real low RPM's .

Please help with any info possible .
Thanks , Tom

Yes you can use a 12 cm with no problems,the smaller the cm the faster it will spool up and less lag it will have.
12 cm came on 12v ,just have to look for them..
