Are you sure about that? BW is known for listing sizes of the turbine's by the inducer side and not by the exducer like most turbo manufacturers. like the s475/83 I had on my truck was an 83 inducer, and only 75mm exducer on the turbine... I won't be able to tell you for sure until I have one of these in my hot little hand to actually measure.

 

You mean you haven't been cataloging this data with all those turbos you've sold??

 

S300's are new to me

S400's I know the skinny on them, that's why I question the actual turbine size on the 300's. And soon I will know.

 

according to borgwarner site its a 76/68 turbine. but i think forcedinductions puts a different wheel on them they have an option for 68, 76 and 80mm.

 

yea I know was listing as an example.
The 62/68 should spool not sure how fast, 68wheel on a 3.0L ? and you can play with the AR to help move that around if need be, maybe choke it with a 68 ar etc.
The 62comp should make 500ish per unit.I think your correct on the 1khp potential...

 

looks like 2.0 evo guys can spool it by 5,000 rpm so add another liter to that, it should spool very well.

 

Positive. S300's are typically listed with the exducer size ie 65,68,71,73. Ran a few of them in the past.
The 68 is a 10 blade design with a similar profile to the 71, and they now offer it in the "new" j type wheel design. It's a kick *** little wheel.

 

looks like the s360 and s366 are really popular the honda and nissan guys. 1.9l honda spooling s366's by 5000 rpm. pretty crazy.

 

Ever consider a pair of s200's?

 

no, they are t3 i was looking for more exhaust flow on this one.
