Hi all just got my R33 GT-R le mans tuned.

Unopened r33 rb26 done just under 100,000 (whether it is legit or not lol)

Mods:

r34 n1 turbos

Ported stock manifolds

Split dump pipes

Xforce front pipes

100cel cat 3"

3.5" cat back

Apexi pods

Trust fmic

Hks evc-5

Link g4+ ecu (no afm's)

Siemens 660cc injectors

Nismo fuel reg

Walbro 255

OS Giken twin plat clutch

Probably more i missed.

Made 300hp on 14psi

365hp on 20psi

Was hoping for abit more after seeing some of the results here, but tuner said to do cams/gears/springs and should get near the 400hp mark.

You should only need cam gears, the cams and springs are more then fine to support over 300kw(400hp)

Might want to get rid of the split dumps and maybe check the fuel is good (i.e. The servo put the correct stuff in their pump)

Thanks for your input,

will probably change cam gears next time i service it, dumps i probably should have changed when the turbos got replaced last week lol :(

and the fuel has been sitting in the tank for around 4 weeks so shouldn't be foul and i used caltex 98, but yeah possibilty of shit fuel maybe.

Depends what split dumps they are, I have split dumps on both my cars, 32 on stock turbs makes 291rwkw at 19psi and the 34 with GT-RSs on a 3.0 made 435awkw on 24psi

Does this seem low/laggy?

34R

Haltech Platinum Pro

N1 manifolds

-9s

HPI dumps and 3" front pipes

Full 3.5" exhaust after merge, catless

Stock airbox with apexi panel

E85 with 1000cc Injextors and 460lph walbro

22psi despite what graph says.

Cam gears, intake 3deg advance, exhaust 3deg retard.

Twin turbo pipe mod

Torque is oddly high also.

Rpm jumo was explained as tacho pickup on the injector wire because he can't get to the coils

I have a second graph that's fine.

You would need to find out exactly what the revs are for us to know but going off the speed it looks like it was dynoed in 3rd or maybe 4th

My 4th goes 205@7000 but then it is a little bit longer the factory

Dropping off at 160kph seems like 3rd if it was revving around or over 7000 rpm?

4th apparently

I just liked to drive them and when they do not do what I want, i changed it until I was happy. So I guess it is up to you, if you feel the car runs great, it is great :)

Going off the Dyno I think yours looks really good and should drive great on the road and track. "Can only guess about the track, lol"

How do you like it ?

Post the 2nd graph

Compression test prior to the dyno came up with 185-190 across all 6, not sure why it was so high. Tried wounding out some power but caused misfires, so wouldn't make any less.

New cams, ECU and valves coming in the next few months, no idea what it will make when retune happens.

    • I have been looking at some setting on the alarms for the Q60 and what buttons do and so and also been looking for details on the alarm in my V37 which is a standard issue with the car. settings like window roll up and a few others seem to not work at all. i cant seem to find exact info on V37 alarms so Q60 is all i can really go off i have not tried 400Z alarm settings or info yet so that will be next. any one got like a sheet of info on the alarm system in the V37 as all my documents are in japanese but i thought the system would basically be like standard through similar models? 
    • I had a fuel smell coming from the drivers rear and pulled the tank out to inspect where it was coming from, turns out the breather hose from the tank to the filler neck was perished. I’m going to Japan next week and I’ll grab it while I’m there  pulled the oil tank apart and started cleaning this crap out of it, some brake cleaner and rags got it looking new again 
    • Hmm. Was quite a few years ago now. I think I bought from a crowd in the US called CDT Audio. The speaker is the HD-6. The HD-6CF would have been the better option (based on T-S parameters), but they were discontinued in 4 ohm at that point in time. The HD-6 is a better driver in almost every other way (than the CF) - just not as good in IB. They still do the HD-6. They might even have a more suitable (for IB) option here.https://www.cdtaudio.com/cdtnew22/products/components/woofers/midwoofers/midwoofers.htm But, here's the rub. I was working in the US a lot back then, so I got them delivered to my US office and then just brought them back to OZ myself. I don't know if they will ship to OZ, and it probably wouldn't be great cost-wise anyway. As to results. They're driven direct off the rear channels of my headunit, because the headunit can be setup to run the rears as subs. So, not a lot of power being fed there. Nevertheless, there's no shortage of volume - the sub levels don't need or want to be boosted at all. The bass is definitely not what you would call "tight". It is definitely a bit delayed compared to a proper sub. But, with the great front soundstage and really good 6.5" woofers in the front doors, I'm getting most of the bass detail from the front and the rear is really only to extend the bottom end a bit. Works for what I'm doing. I mean - until recently you couldn't really hold a conversation in my car due to the fuel pump, and for many years I had tyres so noisy (Kumho KU36 at <50 tread depth) that I had to drive with earplugs anyway!
    • curious to know what drivers you chose and the results? quik mafs, says two 6.5s should roughly equate somewhere between a single 8" or 10" driver. i agree that IB is definitely the way to go in most cars imo.
    • S13 and R32 rear suspension geometry is horrible once you lower it (which everyone does). The camber & toe out ramp is very aggressive, hence it's common for the S13 boys/girls to use a S14 or S15 subframe as the geometry is light years ahead. I'm sure the same can be done on R32s, but I don't know anyone that has done that.
