Boost Control Options

[PSI Parts]

Does the turbo run a bored out internal wastegate or is it standard size still?

SO 14 PSI isn't the minimum setting for the HKS actuator??

Dont know if there are different models but mine certainly goes below 14psi and no doubt will go below 10 if i wanted it to.

Yeah, I'm thinking something around 11-12 PSI would be good for my current application...

Standard turbo, unmodified..

Really limited by standard actuator, am looking for an Rb20 unit but they are hard to come by..

Mods (to be installed within the next 3 months).

JJR front dump.

3/3.5 inch custom catback wih 3.5 inch hi-flow cat.

GReddy Spec-M intercooler.

Nismo fuel pump.

Haltech.

All for an R34 GTT.

Following upgrades (mid-2009):

Poncams.

Injectors.

Aftermarket air filtration (either boxed pod or ARC airbox upgrade).

After that I'll be heading for a HKS GTRS..

For the meanwhile though, I want to achieve 12 psi safely. I've heard some not too good things about solely relying on the EBC...

just for reference for the HKS actuator (not sure if this is accurate, do you trust the internet?)

Length is measured from the hat to the end of the rod I think

Length Boost Pressure

128mm .5 bar 7.25psi

123mm .8 bar 11.6psi

121mm 1.0 bar 14.5psi

119mm 1.2 bar 17.4psi

interested in cheaper wastegates, is it a case of you get what you pay for? Or are there some decent ones out there?

I dont trust that, when i went from .8 to .95 it was about 5mm.
