I picked up a Pair of Ball bearing IHI Turbo's there from a low KM JDM Twin Turbo Subaru Legacy Zero shaft play and they feel real smooth when they spin


the one on the Left is a RHF4 VF13
the one on the right is a RHF4 VF14


they have a shared Waste gate vacuume line and the the exhaust side of the blades seem to be the same, but the compressor side seems to be different.. the angle at which the blades "slice" are diff, one seems flatter then the other...

The exhaust "port" on the left turbo is a little larger then the one on the right as well....

as u can see the Flange to bolt to a manifold is completely wack but i think they can be worked with...

basically i'm trying to decide which turbo to go with...

Left or Right?

i'm looking to make about 200hp on stock internals and retain my AC...
the turbo's are smaller then a T-25... but are apparently comparable to a TD-05 (non big 16 of course)

I'm looking for quick spool up more autoX style...


i couldn't find much info on these turbo's on the net either...

would 10ish Psi and AFC with 450 CC's and MSI to retard the ignition be enough on 91 octane pump gas? only Tuning will be *** dyno tuning tho

i've heard the ZC's love boost?

does this have potential or should a scrap it?

Will i over rev these little turbo's before redline?

depending on what you meant by "will I over rev these turbos"..here are my answers for either scenario:

1) Over-Rev -> Make Turbo Spin Too Fast -> No.

2)Over-Rev -> Will this turbo run out of breath in higher rpms? -> nope, you have a smaller displacement engine than that subaru, and people have used small IHI turbos from the Apex'i kits with great luck revving to 8400+.

thanks...

and what about which turbo u'd take? VF13 or VF14? or it really wont make a diff?

and can i make 200hp with an AFC II DSM injectors MSI box and a Butt dyno without grenading my engine?

you can make 200whp probably pretty easy, as its within the turbo's limits for sure, however the REAL limit lies in your engine. Provided you can supply enough fuel etc, things should work out just fine. As for which one i would pick, i would wait for someone who has more experience with these turbos, i dont know too much about them.
