Hi,

Ive got a manual 34 with turbo back 3" exhaust, apexi pod, hks bov, avcr (0.7 bar) and power fc. The mods were fitted in this order first exhaust > pod > avcr > pfc.

After I had the Power FC tuned I was slightly dissapointed with the 'increase' in power (it was tuned on the road, not a dyno by chapman & chapman). Since then I haven't been too worried about it as the car is running perfectly, and the tuner had ironed out a 'miss' I had on idle and some backfiring between gears caused by the atmo bov. It was only today that I realised my car is hardly any quicker than a standard manual sedan (judging purely by 'feel').

Just now i swapped back to my standard computer and it doesn't really feel hardly any slower..... I am going to run it on a dyno -

My question is how much power (at least) should I expect?

Dan666 was also in my car and agreed it should be a lot quicker......

Any ideas??

Cheers, Paul

Hmmm - cheers bass i'll see how I go.

By the way I ran 13.9 @ 101mph with 2.21 60 foot - That was a 3500 launch (obviosuly not dropping the clutch) and it was on 19" chromes with 235's. Also remember its a sedan... Bass - how did you get a 1.9 60 foot?

I was quite happy with this time - although shoudl i expect more? I think the sedan is at least 150kg heavier than the coupe?

Your missing a fmic.......

I went through the same thing in my car......I got the PFC by necessity as my afm stuffed up and I decided to get a z32 and pfc while I was at it.

I had pretty much the same mods, exhaust, pod, blitz ID3, z32 and pfc.

Have to admit the pfc DID make a little bit of difference but not as much as I expected, but once the front mount was installed and the pfc had a bit more room to do its magic it made a HUGE difference.

Admittedly the dyno is a bit of a happy dyno...but the difference the fmic should be legit as it was done on the same dyno...

I ended up going from 183rwkw before fmic to 220rwkw after fmic.

  • 2 weeks later...

I got a front mount installed a few days ago. The car is alot quicker all the way through the revs. I can't belive it actually seems to have less boost lag - theres alot more response all the way through the revs. It actually felt 'doughy' before, now it feels almost like 2 people have got out of the car. It hasn't been retuned yet, i'm not sure how much would have to be adjusted with just the addition of an intercooler... it will be done this week some time.

I've driven a fair few cars (mainly 32's and 33's) with bigger front mounts and the same mods as mine minus the computer and really have felt hardly quicker than cars with stock coolers... maybe r34's with better breathing on the intake and exhaust and tighter a/f ratios really put alot more pressure on the stock cooler??

Either way i'm happy :P I'll get a dyno readout in a while and let you know - i'd be happy with anything over 190kw...

    • I don't know for sure, but I'd expect them all to be interchangeable given the diff end and hub end don't move/change between any C34 series. Often Nissan will change part numbers and the aftermarket follows those year ranges; but the original part number change doesn't mean other parts won't fit. The change could be a change in material, internal parts or even just supplier. For example, all the RB gearbox to engine bolts are no longer available and there is a new part number instead. The only change is they went from cadmium plated bolts to zinc plated due to the issues manufacturing with Cadmium. They look different but work the same.
    • One year is a bit concerning. Did you try contacting GSP? It says 5 year warranty on the box if I remember correctly. I'm also running their driveshafts on my S2 Stagea.   You could check the part numbers on Amayama for your year. Here's the link for my 1998 which gives the 39100-23U60 part number. Well, that and 39100-23U70. https://www.amayama.com/en/genuine-catalogs/epc/nissan-japan/stagea/wgnc34/6649-rb25det/trans/391 What does it say for yours?
    • I ordered a GSP Front R/H Axle from here - https://justjap.com/products/gsp-premium-front-driveshaft-r-h-nissan-r32-r33-r34-skyline-gtr-stagea-4wd#description It lasted around a year before one of the boots blew out. I'm lowered, but I have GKTech roll center adjusters. One year seems a little premature. I think I'm going to spend the extra money on an OEM cv axle this time. This website - https://tfaspeed.com/collections/nissan-stagea-wgnc34-x-four-parts/products/nissan-stagea-awc34-260rs-rb26-right-front-axle-drive-assembly Makes it sound like the readily available OEM CV axle will only fit 11.1999 Stagea and up (mine is a 2.1997 S1). The JustJap listing didn't mention any years or anything for the GSP axle. Amayama shows '11.1999' and up as well for that part number. As well as 'plastic boot type'. See attached picture. So I guess my question is, does that axle (39100-23U60) really only fit S2 Stagea? It's the front driver side. If it does, I'd love to buy that instead of rolling the dice on another GSP. I've found that OEM one cheaper here: https://www.partsfornissans.com/oem-parts/nismo-jdm-r32-r33-r34-skyline-gtr-r32-gts4-right-front-axle-3910023u60 and here https://www.nissanparts.cc/oem-parts/nismo-shaft-ft-drive-3910023u60 Just a little confused because the JapSpeed listing for the GSP front driver axle doesn't mention any specific years or anything and it fit my S1 Stagea fine. So will 39100-23U60 fit my S1 Stagea even though technically it says '11.1999' and up? What would have changed? Thanks.  
    • Thanks for the info. The only "Issue" I've had with the shifter is I always found the throw between 4th and 6th gear too close. I'm always worried to shift into 4th accidently and sending my motor to the moon. Adam LZ recently came out with a video and stated Serialnine revised their shifters to correct this and will change all the revised parts for 150$. Strangely enough, I contacted Serialnine right after and they denied it and said it's bullshit. I found that strange as he's a distributer. I'll keep this forum post updated on that saga.
    • Yep that is correct. It allows you to adjust the short throw range from what I can tell
