spark plugs for rb20

[bretto]

hey guys i have an r32 gtst and i was just wondering which ngk plugs u guys use??

im not buying platinum im just after the part number or whatever of the ones that u have found best in ur car.

my mods are pod filter, r34 turbo(14psi actuator), r34 arc bolt on i/c(sidemount), gtr fuel pump, fuel regulator and neo 6 injectors(maybe)

cheers guys....brett

BCPR6ES

these are gapped to 0.8mm from the shop and are great at $3 each!

as above..

but one question about your NEO 6 injectors.

AS far as I know, the RB25DET (any RB25det) injectors are not the same as RB20 ones..

rb25's use SIDE feed high impedance whereas the RB20 ones are TOP feed and high impedance..

did you have a new fuel rail made?

I use the irridiums They are bloody fantastic well worth the extra dosh. just be certain to measure the gap as the box says they are set to .7mm but they are not that.(about 1.1 from in the box). .7mm also stops a lot of the misfiring from running a higher boost.

BCPR6ES - they are coppers gapped at 0.8mm...

changed them about 5000ks ago, will be putting the platinum tips back in when when the coppers sh!t themselves...

i am running a pretty stock setup compared to u (12psi boost), and the platinums are in good condition and have already done 30 000 ks.....

check out www.RB20DET.com they have both Copper and platinum

they say the copper should be gapped to 1.1mm

for a stock car yes.

should be 1.1

but if you increase boost, you need a smaller gap otherwise you get misfires in the higher revs with the extra boost.

to tell u the truth man i have no idea, my mate is doing it i havnt got them in the car yet, they are prob going in next weekend so ill know then. but i think the neo 6's are a top feed, dont quote me on that i think i remember my mate saying that they are top feed like mine a while ago...

BCPR6ES-11s in mine.

Gapped down to 1.05. No point gapping them down further unless you are having misfiring problems really. Have to be changed at 10000ks rather than 40000 though which is a pain in the arse.

Similar mods to you except the fuel system is stock and the turbo is a stage 2 GCG number making a very low 173kw atw because of the fueling
