Well the gt4088r is twice as much as the gt4088. Is there any diff. between the two turbos besides one is ball bearing and one is not? Is it worth going ball bearing for the extra 900?

Basically completely different turbos actually

A GT4088R compressor specs are

63.5mm Inducer
88mm Exducer


A GT4088 compressor specs are
64.7mm inducer
88mm Exducer


Turbine specs are

GT4088R= 77mm inducer 78 trim

GT4088= 77mm inducer 84 trim


Different # of blades on the wheels too, they are just totally different unlike a GT4294 and GT4294R which are identical except for being BB and NON BB

 

Very informative Boostfed, good to know.

 

Well maby you can help me then, here is my current set up:

B18c1 sleeved 84mm
CP pistons
Manley turbo tuff rods
P&p head
supertech valves, spring
ITR cams

I am looking for at least 650 whp with a red line of 9k. What would be a better selection for my applcation?
