    Z31 Fairlady 200zr - Who Else Has One?

    in Other Nissan Imports

    Posted · Edited by 200zRRR

    Damn, Ive been on this forum ages and only just noticed this thread.

    Ive got an 86 (at least I think it is an 86?) 200zr over here in Perth, had it for a few years now.

    Pretty stock except for the following:

    -R33 turbo - 10psi

    -Pod filter

    -SAFC2

    -Supra FMIC, 2" stainless piping

    -3" inch exhaust from turbo back

    -Tein springs, bilstein shocks, drift pineapples

    She is up for sale very soon though, would have loved to have done an RB25DET conversion.

    Who Said Rb20 Nics Were Useless?

    I found the EXACT same thing with my NICS in both the Passage and the 200ZR - both with R33 turbos. At revs of around 6k upwards the voltage of the AFM hits pretty high figure of around 4.8v (which is 100% usage according to the SAFC) and as soon as it hits that, the thing is running so ridiculously rich it pisses and farts. Need to calibrate the AFM or use some sort aftermarket management to solve it.

    Yep, if I had a scanner I would post my AFR graph from the dyno run, at 5500rpm the fuel curve goes rich down to 11.0 (and power curve dies accordingly) then it leans to about 12.8 by about 7500rpm. At 12psi it basically blows the spark out and gets even worse power curve. 10psi is only about 7-8psi manifold pressure thanks to shitty 7MGTE supra FMIC Im running.

    The SAFC2 wasnt really designed with the NICS in mind, the AFM setting (4 if I remember correctly) is for the R31 ECCS AFM which I believe is actually somewhat different (possibly different voltage range). I have an SAFC1 (5 dial model) but its got lots less tuning scope. Mine also reports 100% AFM usage by ~5500rpm.

    Basically the options from here are full aftermarket ECU or R32 ECCS engine swap....both come in at about the same mark (~$3K) and I am leaning towards the latter as at least one of my injectors is leaking and she is getting some km's on her now...

    HELP!! engine isnt running so good

    ive got similar probs on my NICS RB20DET, only really has started since I upped the boost (10psi). Basically it sort of hesitates as it hits peak boost, not a total cut but certainly not smooth. Its not pinging (has cooler with the piping thermo wrapped). Im thinking its either ignition or fuel based (not getting enough fuel on boost) but I have already richened the mixture a fair bit and this has still hoped. It idles fine and off boost it runs fine too. Time to test the coil packs (i have some spares at least) and do a plug change. Whats the easiest way to test the coil packs?

    intercooler for r32

    Thats one nice price, I payed $130 for one of these coolers alone 12 months back. Fits in nice on my 200ZR, very similar piping to the 32 (has an RB20Det) and I am impressed with its effectiveness. Running 2" piping with it spools up noice with little lag. They do impede flow a little though so if your wanting more than about 250Hp of air through it you would be pushing it a little.

    I believe that the cop has to have been following you for a certain distance within the speed zone (i.e distance of 5km, not exactly sure how long) at the same speed as you in order to prove the speed you were going (i hope that makes sense). If he doesnt have a radar reading to go on (which he wont because he was on a m/bike) then you could argue that he was not following you for a long enough distance to gain an accurate speed reading. Also that speed change from 100-60 is only a short distance were the road works are, go measure it out with your speedo, you could argue that it is too short a distance to have gained the correct speed, considering he would have to have sped up to catch you this could also create some inaccuracies. Also argue that cos your speedo is in mph you it made it difficult to calculate the exact speed you were travelling and there where no other cars to judge ur speed. Also mention there being no other cars nearby and no-one working on the roadworks.

    It was also a single policeman so you only have the one witness. If he gave you no fine and nothing to prove the speed you were travelling at then where is his proof this took place? Surely you should get a ticket, listing badge number, speed etc. What offence did he charge you with?

    Deny everything.

    Looking for I/C Piping

    My first drive found me blowing a cooler pipe off on charles street (how embarrasing) but after I re-tightened them all, it works a treat, had it up to 14psi :rolleyes:

    One way to get around this is to get a centre punch and put about 4 "punches" around the ends of the pipes, just go from the inside out, this helps to give the clamps something to bind too.

    Or just put some more elbow grease on those hose clamps...I have thus far not blown a hose off running 10psi through mine.
