need an idea on o2 sensor housing.

[xbeck]

alright, i have a precision scm61 internally gated, and the littel devider between the turbine outlet and the wastegate outlet is cut out.(from precision) with that said, i don't know what to do about upgrading the o2 sensor housing. i was thinking that i could cut the same part out on my stock o2 housing and port the crap out of it. but i'm not sure.

any body have any good ideas for me. i would appreciate any help in the matter.

I only know of 3 ways to help boost creep.

1. porting the wastegate passage

2. larger flapper

3. external wastegate

#3 being the absolute cure to creep but the most expensive. 1 and 2 are just going to help but you may still have creep after that.

its either that or restrict your exhaust flow after the turbo more and we know you dont want to do that.

I have an SCM61 too and I wasn't getting any creep from internal wastegate with HRC 3" o2 eliminator, but since I'm going to use nitrous...I don't think internal is the way..also I love atmosphere dump :laugh: ...that love cost me:
-VPE O2 housing for 40mm gate
-40mm wastegate
-Precision t35 etc... turbine housing
-3" downpipe
