t25 vs. 13g

[DSMjrv]

okay so im gonna be purchasing a 92 gst auto in a month... it has a brand new 6bolt in it from a manual, so its got the cams and 450 injectors but it has a 13g turbo...

what can the 13g handle/

all i know about it is that its not as good as the 14b, so how does it compare to a t25/ does it boost as fast/ can it hold boost better than the t25/ whats the max whp output of the 13g

It's all about airflow whether it is expressed in cubic feet per minute (cfm) or pounds per minute (lb/min). In any case it takes about 150 cfm per 100hp....so for 300 horsepower you need a turbo that puts out about 450cfm. The real question is what pressure ratio or boost in psi is this airflow possible with your engine. You need to start thinking airflow and not "boost".

if you can learn the airflow charts that will help you out a great deal.. hope this helped out a bit.

so i know i havent posted a T25 yet because its not worth the upgrade in my opinion. so i produced another one which would benifit you.

14B is a noticeable upgrade from both turbos.
