Send it in. Vortech does great work and they warranty their work for a year. I had them perform a minor rebuild in addition to my impeller upgrade due to a failed seal. Great guys to work with!

Also a solid bet. It depends on what you're going for. I might do this down the line, but this cost twice as much as the rebuild and upgrade from Vortech. Since I'm sticking with stock internals and tranny and I was a little over budget on my build, Vortech's rebuild was perfect for me.

Vortech's rebuild is definitely more affordable.....I'm looking at doing the 928 upgrades later on down the road.....

Let off the throttle and it dumps immediately very loudly and gets quieter as the RPM lowers as you would expect. I get very light fluttering while cruising around 2k to 3k rpm, not accelerating or decelerating.... doesn't effect driveability, just something you can barely hear with the windows down. I can't remember the spring on mine, I just bought what TopGunZ told me to get. I am no expert but if your boost is exhausting while in throttle I would think your spring is too strong and is requiring more boost pressure at lower RPM to shut. Or something is installed wrong. Maybe let the guys know what BPV / BOV your using and someone could shed some light on it.


After driving it for a day it started working fine, I think maybe because it was used kit it was gummed up or sticking, but it's the qrj with the 1.5 spring from topz, I just bought it used from chasez

If it's just the impeller you want they can be installed yourself real easy. Just did one on a mustang here in the shop, surprisingly it ran pretty decent before he took it to be tuned.

What's the status on this kit? I am hoping it comes out after the z35 reveal in October (hopefully) so I can decide if I want to boost the z34 or wait for the z35.

You know if it comes out beforehand.... you could also wait the eternity for the Z35 to make your decision =)

Pessimist! lol. I am just hoping because if there's no z35 concept this year, then I am pretty much writing it off as not happening. Then the debate becomes do I want some comfort in exchange for weight and get a pre-owned q60 coupe in a year or 2 or stick to the z34 and boost it.

That all depends on how much power you want. If 400whp is enough, buy the Q cuz factory turbo > than aftermarket N/A turbo build. If you want more power then keep it and buy a FI TT kit.

I think i would be happy with the power of the Z with this kit. I am debating on waiting because of the noise NVH I have right now. I figure with a factory boosted Z, I would retain mostly OEM NVH and comfort because I would be able to much more easily tune good power out of it without too many mods. I hear mid 400s whp/trq with intake, secondary DPs, exhaust and tune. I don't really need luxury which is why I am hoping for a new Z instead of the Q. I just want normal car comfort with good performance, basically my Z's fun to drive-ness with more power and less roughness.

Thanks for the input fellas.

...on a Mustang, no less...

Yep finally got on the dyno but was only able to dyno my daily map on 19 deg of timing. Made 696/500. Im between 16-17 psi. We are taking Aarons A-A kit to all new heights. Will be going back within the next few weeks to get numbers on my "kill" tune. Seb has it set at 22 deg of timing. Oh yeah and all this was done on a Mustang dyno for what it is worth.
