RB20det NICS info

[200zRRR]

hey guyz,

i got 200zr with old NICS rb20det, just wondering main differences between NICS and ECCS? i know turbo is diff but what bout injectors, afm and ECU?

I have an r32 turbo on atm but going the r33 route soon, just wonderin if this is straight bolt on yeh?

also canthe NICS version be epromed or even tuned thorugh ECU?

Also the stock boost controller has an electronic like solenoid connected to the vacuum piping to wastegate, can i wire in EBC around this?

any info much appreciated

come and visit.

we have R31's (the early models) with NICS motors. This has been a question of late too

AFM & ECU different Injectors are same. the main Difference are the inlet manifold. the NICS has a 12 port inlet manifold the head is 6 port, there are two sets of runners on the NICS and only 6 on the ECCS, the theory on the NICS was that the two set of 6 runners are different length under low revs, or take off, the long ports are open giving more torque in theory. After the revs build up the second lot of runners are opened through the butterflys which are shorter for top end power. Turbo yes the RB25 bolts straight on, but you must get the banjos and oil lines as well. Next quetion the NICS chip is currently being worked on by a couple of people to see if it can be re-programmed so will have to wait and see.

the actual heads are different in deisgn too

The injectors arn't the same . R32 has high impedence 270cc . R31 has low inpedence 220cc.

[R31Heaven]

He is talking about a redtop ECCS I assume??? so the injectors are the same.

[R32-GTS]

THe injectors are different . Even on the red top. So get some first hand experience before correcting me.

[R31Heaven]

I was not having a go at you R32-GTS I stand corrected. In what way are they differnet as in impedence or CC? are they high impedence?

[R32-GTS]

NICS and RED top ECCS are 220cc low inpedence. R32 has 270cc high impedence

[R31Heaven]

So the NICS & ECCS redtop injectors are the same, low impedence 220cc??? the R32 Silver top are different I am confused in one post you say the Redtop Nics & Redtop ECCS are different and in the last one you say they are the same.

well R31Heaven... be prepared to stand correct by the man with the expirirance :bahaha: :bahaha:

[R32-GTS]

They are the same injector . But for some reason some are white tops and some are purple. May vary depending on the year.

if it's from a year or two back...

Or maybe longer.

I've got that one (about 5 copies of it ) R31Heaven i think i've showed you a copy of it long ago...

It doesnt really have a lot of stuff in it though.

rsx84, can you scan it and e-mail it to me?
