scwitzer (spell?) makes most of them that are considered a S300...i would go with a Phat shaft turbo from Industrial Injection instead...seem to be able to hold higher PSI better, just my opinion and im sure people will disagree with me

IF your going for a bone stock S300 (like right off a stock application) a HX40 will flow more air. Any one that has been worked from a manufacturer though will beat its ***!

the S300 is still a really good turbo. everyone has their opinions. i've heard alot about both the phat shaft and the S300. schwitzer has a pretty prestegious name and i'm partial to them. so; either one will work fine for your application provided that it is built with the correct housing,turbine, and compressor wheel.

on a different note; what model ball bearing turbo would fit and be comparable to the S300?

For a truck around 400rwhp (especially a 1st Gen) that will tow and play, I think it's hard to beat a Super HX40. It spools faster than an S300, and will support plenty of air.

However, if it is all out performance you are looking for, a 62/71/14 would be the turbo I would look for. Laggier than an HX40, but if done correctly will support much more air. Me personally, I wouldn't go with a 62/65. I thought about it, but the high rwhp 1st Gen guys didn't advise it. Said the choking from the 62/65 isn't worth the better spool up. These are all opinions of course. I know guys with 62/65's that love them.

I know you can find brand new Super 40's for under 1K, but a comparable Schwitzer is considerably more. I'm going with a Super HX40 myself.
