rb20 redtop eccs vs silvertop eccs

[PAGZ]

any1 no the main diferences between the 2, ive heard that the redtop block can handle more punishing hp than the silvertop block but the silvertop head has more flow?? would any1 like to clear this up? just looking 4 info on the 2 thanx :wave:

havn't heard anything of the type
silvertop has better stock turbo and comes with factory bov
also a big advantage was a tuneable rom but i believe you can get that done on redtops now as well
other than that there's no performance advantage, mine matched or bettered silvertop mod for mod before i decided on engine swap

put a NICS motor in, i hear those are pretty good.

theres not a huge difference between them as they are all rb20's and are 2L straight six's. slight improvements from redtop nics to redtop eccs to silvertop, but nothing major.
if your choosing one, go the silvertop. slightly better engine, much more parts available.

i have heard that the nics head is higher flowing than the eccs but you cant fit them to the later motors due to some gallery differences?
correct me if im wrong

ive heard sumwhere that the redtop eccs has a slightly stronger block on it compared 2 the silvertop, just wondering becoz i dropt a 2.2litre redtop into my car recently just trying to find out if there is any major diferences between the 2 cheers fellas.

redtop also has inlet butterflies, don't think silvertop does

different impendance injectors, different afm, different cas, different (not as easily tuned) ecu, no bov, slightly smaller turbo.. just off the top of my head.

nics has the strongest block but doesn't respond to mods well at all

yeah i drove a nics that had an auto and an r34 turbo
was horrible lol
switch to an eccs redtop and 5 speed made a massive difference
