Hey all,

Who can tell me the technical difference between the 450HP hi flow and 500HP hi flow turbos that GCG offer ?? (and don't say 50 HP please)

I'm sure Sydneykid et al will know....

Is it that the 500HP job can handle more boost or does it flow better ? And if so , why ?

Thanks in advance.

GCG Got back to me with this:

The wheel sizes within the turbocharger are larger on the stage 2

conversion. Compressor wheel is a H trim TO4, turbine wheel is a T34 79 trim.

I need an interpreter !!!

What does all this mean ???

How can I identify if I have a Stage I or Stage II ?

Take your turbo off - you will find you have the same thing.

I cant even get the heatshield off - it must have been tightened by someone stronger than me when they did the turbo and leaking gasket down there.

I was pointing it out just in case it could have been a problem.

    • Am I correct in assuming that the R35's are getting the classic skyline haircut off the odometer?  Quick search on carsales, there are 33 08 and 09 GTR's for sale, only 2 of them have more then 100,000km's on them (116,075 and 110,000 respectively).  And somehow there are about 25 for sale with around 60,000kms? Looks like the classic skyline haircut to me =/
    • @Stringycheese  Have you only gone to the one blue slip workshop?  There will be a heap of them where ever you live, good odds that the next place you go to will pass the car.  Unfortunately (or fortunately?) every blue slip / engineering workshop will be different and will be happy passing or failing different things - despite working from the same set of rules. It's kinda like 2 lawyers arguing over a piece of legislation, each saying their interpretation is correct. Might seem strange that this happens when it comes to getting a modified car passed, but this is very much a thing. A big part of the game is finding an engineer / workshop that is on the same page as you.
    • Bah. I daily mine. ~60km per work day, 10-12 thousand km per year. What's the point of having a dirty old Datto and leaving it in the shed. It needs to be driven and enjoyed while the govco allows us to do so. It will only be a few years before we're forbidden to even start up internal combustion engines.
    • Judging by that spring perch and the normal looking spring on it - not a coilover. Well.... it is a coilover, just a stock format coilover, rather than what everyone calls a coilover.
    • Yes it is. We get stock from Nismo directly. I'm happy to take photos/video of it as proof before I ship it with timestamps or whathaveyou.
