Roy Posted March 22, 2004 Share Posted March 22, 2004 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...

RBN1 Posted March 22, 2004 Share Posted March 22, 2004 the black top is the one that comes with r32, cefiro etc. Your rocker covers have most likely been painted?

RBVS Posted March 22, 2004 Share Posted March 22, 2004 didnt know you could get black and red rb's thought it was just the sr's, interesting oops, black or silver, with rbs, should pay more attention.

Elithrar Posted March 22, 2004 Share Posted March 22, 2004 Just to clarify for some people, as the information above is a little conflicting. The RB20DET came in both Red and Silver -top variants.

Kinks Posted March 22, 2004 Share Posted March 22, 2004 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.

DCIEVE Posted March 22, 2004 Share Posted March 22, 2004 age and the ecu are the only points against the red top (eccs version) Link to comment https://www.sau.com.au/forums/topic/36824-rb20-red-top-v-rb20-black-top/#findComment-736058 Share on other sites More sharing options...
R31Nismoid Posted March 22, 2004 Share Posted March 22, 2004 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 $$$ Link to comment https://www.sau.com.au/forums/topic/36824-rb20-red-top-v-rb20-black-top/#findComment-736281 Share on other sites More sharing options...
WazR32GTSt Posted March 22, 2004 Share Posted March 22, 2004 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!
