silver top has better intake manifold head and electronics and makes more power

[FATGTS-R]

Red tops (there are two red versions, NICS and ECCS) have a 12 port head as opposed to silver tops 6.

Reds have a smaller turbo. Reds have low imp hose tail injectors, silver has high imp O ring type.

Reds are older and from the 31 series cars and parts are a lot scarcer.

Factory VS factory setup the silver has more power. Engines alone with identical ancillaries I reckon there would not be much if anything at all in the power difference.

so how much power difference are we talkin about here? about 20kw?

[jas/slo32]

stuff all but if you had the silver rocker cover head manifolds etc you could bolt it to the read rocker cover bottom enn bcaus there both the same

<{POST_SNAPBACK}>

more than that, i think it's like 40kw

the ECU on the NICS RB20 is really poo poo, to get anything worth while from it you need some re-tuning, head work and a bigger turbo etc etc

Got rid of mine before the car even hit the street

the redtop head vs the silvertop is different in many ways, also the eletrics in the heads are prone to failing - IE CAS sensors etc.

Try finding a CAS for a redtop as there are 3 different ones

Its not worth the hassle

stick with silver

The silver top had intake and exhaust lobe seperation of 6deg for each cylinder. To aid in the swirl effect. Pretty cool idea I thought.

always wanted to know what the ECCS stands for?
