made 476 on a borg warner s366 on the smaller housing.. i think it wwas a .88 rear housing...

what do you guys think?

 

What boost? Porting? Give more details...

 

21lbs ... Mild street port ... Oem seals.. Pump gas and meth... Hks twin power ...

 

I would say its solid power. Given that its 66mm wheel there is much more power to be had in higher boost. In the end of the day its just about if you are happy with performance.

 

i would like to change the hot side to a bigger one just dont know who to contact for a good price...

 

Why? Turbine itself is huge, there is no need for big A/R numbers as you´ve maybe seen floating around. You must realize that where usual 66-67mm wheels have 74mm turbine with 65mm exducer, this one has 80mm with 73mm exducer, its huge difference. Bigger housing would sacrifice spool without promoting any gain in top end.

Also what is your manifold setup? Collected tubular?

 

Intake mani is oem... Exaugst is tubular
