I think you will find most ppl refer to them as silver top and red top.

There is a fair bit of difference, with different inlet manifold setups, different blocks (some say the red top has stronger block) different turbos, different ECUS.

Whether the cams and compression ratio ares the same i cant tell you, but considerign the silver tops make more power std, something like 145 vs 160kws and are newer with much niocer turbos then id be lookign for a silver top...

also, the red top came in NICS and ECCS versions. the NICS version had a head design that gave it better low down torque but strangled it up top. the ECCS is much closer to the silver-top RB20 in design and power output.

Personally I wouldn't bother with a NICS. either ECCS (the engine that's in my car) or a silvertop - the latter is preferable due to its newer vintage and slightly higher power output.

Also sensors and parts for the red-top.

There are 3 different CAS for the red top series.

Silver top heads dont bolt on etc etc.

So if you cook your red-top... finding parts is harder than it would be for a silver and in the end will cost ya more $$$

I'll make a list of what i have read/heard about the differences. please correct me if i'm wrong...

red top has a lower compression ratio

red top has a non-BB turbo

they both have different cams, head design, and ECU

that's all i can remember at the moment.

basically, don't go the red top unless its dirt cheap!

    • 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.
