Rb 20 Red Top

[SIKLNE]

Hey everyone, Just wanted to let anyone interested in knowing that today I drove an R32 with a Red Top RB 20, It's the ECCS Version, I had always thought that the Red Top was a Lesser version of the Silver Top due to it was the earlier model of the RB 20, But to my surprise this thing seriously moved, It had Front Mount cooler, Bigger Fuel pump, 550 cc Sard Injectors, Had a bigger turbo on it or a different turbo, not sure what sort but looked pretty standard, had a few other small mods, Nice Clutch, Boost was around 10 PSI, Didn't really see it spike, but yeah it really moved, and it seemed to love it, What is the difference with the ECCS Version RB 20 Red Top and the Silver Top RB 20? I've got mates with R32's and 3's with the Normal color Silver Top and this thing felt like it would have destroyed them! The owner of the car claimed that some people believe that the Red Top actually has a stronger bottom end, Just hope someone can shed some light on the major difference with these engines.

Kind Regards.

Red tops are inferior - can't deny that. They have more electrical problems than they are worth.

They most certainly do not have stronger bottom ends, whoever said that is full of it.

Your in a car with a tune, a larger turbo and so on... of course its going to feel faster than a silvertop with a stock turbo mate.

Put the same gear on a silver top - it would be the same if not better.

I have read in several places that the red tops do have ticker blocks, but the RB20s dont want for block strength, remember they run the same cylinder spacing as the RB30 but only have 78mm bore rather then 86, so there is plenty of grunt in any RB20 block.

Odds are the person had the earlier RB20 rocker covers on a later model RB20...lol i know thats what i have in store for my car if/when i get it back and i cbf'd

i got a redtop eccs bored to a 2.2 and i dont have any electrical faults, has a pretty nice curve to compaired to my old silvertop.

Good for you - plenty of other people however have so many niggling issue's its simply a waste of time wen silvertops (and loom) are less than $1,000.

I am one such person but mine is a GTS4-R

Stacey's old HR31 89 model engine was essentially a silver top with red rocker covers...the engine was no different to the R32 gts-t engine. Made 180rwkw (auto tranny) unopened over 10 years ago...a lot of power back then...especially for a girls daily driver.

lol - no chance i will go back to a red top... my first one was enough drama's for a lifetime

god damn nissan and getting different sensors between 3 series of red tops... if you were the unrucky person to have a smaller run sensor'd option - was a tough life

[funkymonkey]

lol I'm still trying to figure out wtf series RB is in my ceffy. It uses different coilpacks to my R32's, has a silver top, but uses the same alternator, starter motor etc as an R31. It has ECCS but the ECU doesn't use CONSULT.

sif, if it blows I'm goin RB25. altho given that its a stock engine running stock boost thru a stock turbo, in a daily driver, chances of it blowing are minimal. my 32's engine on the other hand...
