Hks Gt-zz Turbos

[Topaz]

Has anyone heard or read any info on these turbos yet?, all I could find is that they are rated at 330PS which is right in the middle of the GT-SS and GT-RS turbos. The ZZ's are probably what I'd be looking at getting if the price is about right for me, if they are too expensive I will stick to the GT-SS's just to get the steel wheel turbos for a bit more boost.

Also do both turbos have to be rated at say 330PS to get a maximum of 330PS from the car at the wheels or does that only relate to single turbo cars?

P.S. I found this sheet with GTR, HKS, NISMO & TOMEI turbo ratings

The GT-ZZ's are the replacement for the 2530 units.

Late last year there was a thread on this forum regarding this turbo with pictures. It might pay to do a search as there was much discussion about these units.

Yes GT-ZZ is the new replacement for the 2530, but it has not been released for sale yet.

I have heard that a pair of GT-ZZs on a Nissan 350Z engine spool up to full boost (4.5psi maximum on that engine) at only 2,000 Rpm.

For size they slot inbetween the GTSS and GTRS. The HKS dealers do not have them yet, but it won't be long.

You are forgetting the basics, power is proportional to AIRFLOW not boost pressure.

The standard 350Z has a high compression normally aspirated V6, which is pretty powerful anyway. 4.5psi is still enough to crank out almost 400 Hp. Laugh all you want, but it also has massive torque from 2,000 Rpm where it reaches full boost, on all the way up to the redline, and virtually no lag with these new turbos.

Remember it has almost an extra litre of engine capacity over a GTR, and reaches full boost at half the Rpm. It is an absolute torque monster in any of it's six gears according to peapole that have driven it.

2 wont flow 330ps, one will so 660 is the claim,Garret 2560s will do the same for a lot less money tho prolly not quite as good but would be close also leaving the extra money saved for other supports.

Thanks N I B, so a GTR with 2 other these can produce 660PS. Horsepower is either slightly more or slightly less than PS....I can't remember which way it swings
