turbo question

[driftking777]

what do you guys think is a better turbo...internal wastegate or external wastegate, also what is a good BOV?

35mm Tial Externaly gated Turbo, I like HKS so far, i really havent played around with any other BOVs

you dont need an external wastegate for low boost setting their mainly for hi boosted car and when you really want to fine tune boost seetings.. a internal wastegate is good for a street application.. as for bov,
hks ssqv-hi pitched wistle
greedy gt- a deep pphhhiissshhh sound
turbonetics rfl- really fu*k loud phiissh sound
also the sr20det and ka24de-t dosnt run well with the bov vented into the air cause the car to run rich loss power and back fire and also shitty fuel economy..

hey turbo2nr did you custom you turbo for your 91 probe gt or did you get it from somewhere? Im lookin for one? I know TKT did turbos but stopped so...im lost on turbos for the KL-ZE?

How can venting a BOV into the air make the car run rich? And if it does, couldn't you tune it out by ajusting the AF ratio?

drift king, the 91 probe gt's came with a factory turbo my motor is a sohc 2.2l turbo (f2t) i have a ihi rb6 vf11 .54a/r probetalk is a good place to look for turbos for those motor.. most likely you need to make a mainfold and get a turbo to fit it..

as for logik23, venting the bov into the atmospher cause you car to run rich b/c the air is suppose to go bak into the map sesor to get a reading about how much fuel to inject it and b/c no air is present b/c it is vented into the atmosphere the ecu sends more fuel into the chamber to equal it up.. and you car runs rich. and so far no one has been able to tune the air fuel to correct it unless u have stand alone.. btw if you are thinking a apex-i safc will do this your wrong, the afc cannot remap the factory ecu and cannot changer the af ratio..

Damn so you can't get the coolness of that sound without messing with ur AF ratio...that's BS, I'll get an RB. :-P

It runs rich because your sensor registered that there was a surplus of air. Then it is taken away through the bov and the computer wants to run it like it had all that air. After that it will run rough untill it recovers.
