    GCG have a lot of work carried out by Garrett(the same Garrett that stuffed my engine, and wouldn't pay to fix their suspect workmanship). There are many horror stories doing the rounds, about both companies. Caution recommended.:eek::eek::zlove:

    GCG sells

    garrett turbo's its their main brand! I assumed the package Jason is eluding to, would be Garrett. Atm this is all speculation, lets wait and see what turns up.

    Im with Chilli, caution recommended. And yes Beaver lets wait and hopefully a nice pressy pops out for us zedders.

    Anyways, apart from this- when i change my turbos what are my options on work to the manifolds?

    What can i do to the manifolds and what are the benfits of it.

    Pentroof manifolds available for circa 3k.

    Z1 have just made what appears to be a copy of the pentroofs, but they are not widely available at the moment. They are being prototyped on a HKS2530 car this week. No information on flow rate yet.

    There are also AAE manifolds, similar flow rates to the MSP from memory, price was lower if I recall correctly.

    Okay to clarify a little further.

    An american kit was purchased and checked out and found to be quite dodgy when it came to overall quality, so the kit was taken to Mark at GCG turbos to see about duplicating the kit using the same brand new in house modified Garrett turbos.

    These will be a first locally produced bolt on affair and will most likely at this point in time cost around the same dollars or even less than importing the overseas kits there will also be local warranty aswell.

    All the optioned are based on the Garrett turbo lineup and include options like comp cover size, comp wheel, exducer, exhaust cover etc to whatever specs we want within reason. Mark can also hopefully do a HKS rear housing which is GT35 wheel compliant and externally gated. A set of stock manis will be dropped off to GCG soon to see about modifying them for external gates.

    This initiative has been taken by UAS due to the high price of there initial GT28RS kit which required custom engine mounts, piping etc etc etc this new kit will hopefully come in at around the 4k mark depending on options which is pretty good for 2 brand new bolt on turbos with all gaskets water lines oil lines etc and if it doesnt fit for whatever reason GCG is around the corner like the the US counterparts.

    so thats the updated story and hopefully have more to add in a week or so.

    Jason are they garrets? or copies....

    This kit from Z1 Z1 300ZX GT675RS Turbo kit (GT28 RS) is $3600 AUD

    The ones Mark is working on is the same turbos? rated at 700rwhp

    If he can give us a price under 4k for a similar kit (not bigger because than you need alot of engine work just to get it to spool on time) and maybe under 5k including manifolds and/or 5bolt dumps than i would be interested.

    They are Garretts Ali and assembled and or modified by GCG in house as per customers orders. Mine will be a special maybe one off set of custom Garretts capable of nearly 1000hp flow with the spray.

    Not sure on pricing though yet will hopefully know more in a week or two. That $3600 doesnt include shipping though. Z1 use Fedex which will be around 280 USD so overall cost is more like $4200 AUD plus no warranty etc unless you want to send it all back to the US.

    Why?

    Why do you need to block out the plates on a car in motor show with thousands of people walking past?:eek:

    Good kit it's what is going on my car. Build quality is top notch there is one potential issue with the potential for leaking on the oil drain line but this has been discussed alot in another thread.

    Are you sure it's what you want though? You need a pretty tough engine to take advantage of all that potential kw, not to mention manifolds, fuel etc etc

    Whoever said it's alot of money definately does not know what they're talking about. The amount of R&D to make a truly bolt on kit for these is huge and as ZisLuv said what else is available in this price range?

    UAS kit is a little different in that it uses different (slightly) turbos and the price includes dumps, extrude honed manifolds, and 60mm piping to do away with your factory inlet tract and relocate pods to under headlights.

    But yeah to answer your question good kit and will make alot of power with the right mods. If you're looking at turbos of this kind you may also want to consider purchasing my cams from the for sale section :D ;) :D

    More info

    AK Z1 have not modified the turbos to make them spool faster, they simply use the .64 AR turbo. No mods there simply turbo selection. They can also supply in a larger AR for more top end power potential but more lag.

    Also NOT the same kit as offered by UAS. As above the turbos are different (UAS use hose style inlet, marginally larger) and the kit is far more comprehensive.

    The Z1 kit is supposed to be a true bolt on affair as well, ie clocked and test fitted to a block before they leave the factory.

    I think

    the HKS GT2530 BB is right on top off my list. With the proper mods( manifold injectors ect) they will easily make 500rwhp, and hit 10psi @ 3000rpm and 14psi well before 4000rpm, for about 4k bolt on.

    Hey Beaver

    How does HKS GT2530 BB compare to the Z1 300ZX GT675RS in terms of performance etc?

    Also the HKS kit is $3900 where the Z1 kit is about $2900. What do you get in the HKS kit that you dont in the Z1 kit?

    thanks

    You need manifolds

    to go with the HKS turbos, because they have external gates, for a start! that is the down side. The rest is all up!
    Work calls.

    In the picture on COZ for the KSH Turbo kit, is everything shown in that picture included with the kit? Because it looks like it comes with manifolds and dump pipes.

    Ali it doesnt mate I checked on the HKS website

    http://www.hksusa.com/products/?id=1768

    The turbos in GT2530 form are rated to around 280hp each with .64 rear housings and are internally gated in that kit. There is an external rear housing option which is what GCG will be offering but doesnt come direct from HKS like that.

    Short answer no the manifolds pipes wastegates etc do not come with that kit on Coz website cross reference the part number on Coz site to the one on the HKS site.

    Sorry to burst your bubble mate but a full kit like that would set you back more like 7k USD plus shipping
