Compressor wheel swap

can i swap a 16G compressor wheel with a 14B compressor wheel without machining the stock TD05H housing?

Nope...

so in order to do "build" a 16G out of a stock TD05H i would need a new compressor wheel and housing, plus some machine work on the carriage??

You would need a new comp wheel and then just machine the compressor housing you are using.The CHRA should be fine.What do you plan on putting this on?

its not for me. someone else is puttin it on a DSM i just got it from them to rebuild and then got to looking and thought maybe i could upgrade it fairly cheap. i found some compressor wheels on Ebay. i have been look into it more since the OP and i can machine the inducer bore myself so if thats all i have to do then its up to this guy on how much he wants to spend on this rebuild

What about upgrading comp wheel in a VF30 ... how big could you go?? is there any substantial benefits with it? I'm running an EJ20 with a VF30 full TBE, protune, 880cc injectors and big walbro if it really matters ???

Bigger wheel=more airflow.It would be like having a bigger turbo(sorta).It's kinda expensive and not worth it on a VF/IHI turbo.Sell the turbo and buy a Evo 16G or 18G.

I'm assuming that would help with turbo lag as well???

Nope.Bigger compressor with same turbine=more lag.

really ... so if you wanted to virtually eliminate turbo lag or at least drop lag to about the 2500rpm range ... how would you go about it ?

compressor and housing combos aren't really going to change things fundamentally. More flow = more lag. Lag reduction is usually done by things like using a ball bearing design (like a VF34 instead of a VF30) or twin scroll or through tuning (anti-lag). Also, changing the piping around to reduce the distances can cut lag considerably (not that it's easy or cheap).

Equal length headers and a tune with a 3 port BCS.Also porting/polishing the turbo with turbo blanket or ceramic coating.

sorry whats "a 3 port BCS"

dumdum · 09-12-2007, 09:43 AM

BCS = Boost Control Solenoid
3 port BCS= Perrrin,Prodrive or GM solenoid
