I have no issue with that
What type of port work exactly?

Your ported turbo compressor inlet option. I would like a price of this turbo w/that option if available in a .84 ex. Do you offer options on divided/non divided turbine housings? I'd prefer the non divided to match up to my manifold. Thanks in advance.

sean,
dick lambert received his GT3574 today, a day ahead of schedule. he asked me to thank everyone at A Spec for the speedy delivery and hopes to have it up and running on the dyno at Beyond Redline in Green Bay next week.
that is if we can convince him to leave it at the shop so they can fixture it... he was muttering something about putting it under his pillow.
maybe he will grow up... probably not.
thanks,
hc

Thanks, and no problem some people get lucky and some get stuck waiting
It depends on wether or not turbine housings or wheels are on backorder. Please keep me informed on the progress.

Ok, here's the update as promised.
Last year made 437 rwhp and 340 torque @ 16lbs. Injector duty cycle near 90% on 4x 720cc injectors and had to stop. Now running a full KGParts setup, rails, fpr, etc. 750cc x2 and 1600cc x 2
Today's best:
447 rwhp and 358 torque @ 18lbs. Fuel concerns were taken care of, duty cycles were no higher than 61%. I've always wanted the car to be quiet so I've been running Racing Beat's catback. Well, it just couldn't keep up. Definitely choaking it.

You can easily see the lines getting closer and closer towards the top, just can't flow enough. I can live with that as I value whats left of my hearing more than those last 20-30 hp.
I was under the impression that the GT3574 was a happy turbo at moderate boost level 15-18 psi. But HOLY HELL does it go crazy when you let it rip at 20 psi + . Some other owner who is a little more setup for it, please push one of these bad boys at 20-22lbs. The turbo just goes crazy
