I was wondering if anyone has any experience with the XS TO4X Squared turbo. I am trying to get a good idea as of where it stands vs a T78 ot GT40R turbo's. I do know it has a 1.00 hotside and 84mm comp wheel 62 trim. I am running a XS TO4S and am considering upgrading cause I need a rebuild and want something that will bolt onto my manifold.

 

stay away from xs =] a t78 is a great turbo

 

What's wrong with XS? I am very pleased with my TO4S.

 

well i was happy with my to4s till i took it apart.. no 360 degree thrust bearings, nothing was brass, blah blah.. it ran ok on my street port, it ate itself in a week after i put it on the half-bridge setup

 

I think there are better turbos out there than the T04X2, I think its probably similar in size to something between a T78 and T88 Greddy.

 

Shoot Xcessive a PM. He ran one for quite awhile. Or call Ralph at Groundzeromotorsports.com CJ

 

Tony Yeh (rotary xecret7) has this turbo on his RX7. He made 536rwhp at 1.8kg? with C16 race gas. As far as response and low end I don't know the details but I hear it's supposed to spool faster than a T78.

 

my friend had XS turbo kit on his R1. make 430WHP(1.1KG). less lag than my T04R. but my trubo pull much stronger(?) even I am 20WHP down.dont know why.
