o2 housing

[kbrock1]

Just wondering how good the evo 3 o2 housings are at prevent boost creep. I am looking at buying an o2 housing atmospher dump but I can't find any that are real good quality for the same price as the evo 3. I have a 16g with eagle rods, wiesco pistons, hks cams, and alots of other stuff just wondering if the atmosphere dump is the only way to get rid of the boost creep.

get the evo o2 housing and port the crap out of the wastgate runner

I just got all EVO compnents ported from buschur and they still suggested a 2.5" exhaust to prevent creep.

Is the atmosphere dump 02 housing from punishment racing any good it is $135 shipped. I should have no creep with it but is it good quality

I forgot to mention I have 3in exhaust with no cat.

The size of the wastegate is the real fix. I had a 20G on my '89 Conquest. I wired the wastegate wide open and still went past my 20 psi seting on my EVC to 27 PSI by 6k and it would have just gone on until the motor blew. for that turbo on a quest an external would be best though some have relieved the problem by opening the wastegate a few thousanths more.
