Question: Will a t3/t04e 60 trim ar .63/.70 be to laggy on B20

[levan634]

Just like the topic header says....Will this turbo be to laggy for my b20....the turbo is a stage1 turbine...i only plan to run 10-12 pounds post up your opinions....thanks Les

The problem i you'll be using that turbo way out of it effeciency range. B20 don't like boost in stock form. That turbo is designed for more HP then what you can handle stock.

I agree, with that big of a turbo you will tear a part a stock internal b20. It will eat up those thin cylinder walls like french toast on a saturday morning.

i know the b20 block isnt that strong and im not worried about that.....cause proper tuning should be essential....all i was wondering is if this will lag....the compressor map for this turbo....non of points are gonna be plotted outside its efficiency range.....so yeah how is that inefficient....fill me in

Bump added full setup....

Not sure about your specific setup, but I am runnign a .60/.80 GT28 on my stock b18, and it hits full boost at 4k, in 2nd.
Everyone told me the .80 wouldnt spool up till the redline, it starts to build boost at 3k. I'd tell you it depends on the quality of the rest of your build, but mine is so shitty it cant explain it away. Your ---- will probably work out ok.

[levan634]

isnt a GT28 ball bearing though....so wouldnt that spool up faster than any t3/t4 hybrid

[levan634]

bump....
