I haven't really taken any mate. Car isn't at home at the moment. Are you looking at doing a twin 3 inch?

Yea mate, I'm doing a twin 3inch on my 32. I got AES building me some custom mufflers ATM, so I won't have any clearance issues, mine will be alil diffrent, as I'm running twin 3inch to the diff and than 4inch into the rear muffler.

Car is finally booked into Insight on the 19th of April for the ECU, fuel system and sensor wire in plus the tune. Thats the good news. The bad news is that V-cam aint gonna fit with my pistons and ho

Small update.... ITS RUNNING. Fired first go! Smells like burnt dust apparently .

A 9174 would just make the EGP pressure issue worse and in my mind it seems like a bit of a GT RS shit going on. Not that it's horrendously bad (It wouldn't be no twin buttplug pressures), That's NOT

Rang NPC and Exedy today. Exedy were pretty damn helpful. What I need is the dimensions and tooth count of this spline hub. They might have something off the shelf which might suit me to a tee and just plonk it in my casing. Sounds good to me.

Basically its tuned length front pipes, into a muffler where the stocker lives which has two 3 inch 'holes', twin 3 inch out then it joins into one piece around the diff. Not enough room for two pipes. Then back out into twin 3 inch, muffler then twin tips.

yeh those tuned length front pipes in particular is what I wanted a pic of, just to get a rough idea on how they went about em, as theres so many different ways to run em.

Cheers

I know the rear one wraps over the front pipe. Makes getting them off an absolute bastard.

I just went through my photobucket, no pics of the fronts there :(.

If Exeedy can't supply a centre hub for your clutch to match your input shaft, they may be able to provide you with something that will be close. Ie, sharing the same number of splines, but a fraction too small for the shaft.

Given to a machine shop with a CNC EDM wire cutter, they could quickly re-cut the spline to suit your requirements.

I've heard similar good reports about the NPC carbon clutches too. Streetable etc. There was a guy up here with an 800ish hp R34 that used an NPC clutch to allow the holinger box to link up properly. My exeedy carbon D twin is taking some getting used too. It tends to slip when its cold, but get it hot just once and it holds really well. It would be interesting to know if the NPC's also have to be up to temperature to get them to hold.

I'll see what comes up in the next few days. I'll get the relevant info off PPG and go from there. Thanks for the info, Ian!

I had custom tuned length front pipes on my GTR years ago, it definitely kept the gearbox oil warm

And the heat that comes through the floor, esp passenger side. Jesus!

Nothing yet, Eric. Car is still at the panel beaters.

Oil still hasn't been drained out of the box yet lol.

Michael Hill has given me his spare stock GTR box so hopefully over the Easter break I'll get it in then get my one stripped down.

I am considering putting a PPG dog set into a Getrag. The ratios are pretty sweet, even with the 4.11's, although would be better with the taller diff ratios.

You're having problems finding a center hub for the larger input shaft?

I had that problem when I went with the PPG dog box and larger spline input. Ended up going with a twin carbonetic clutch which has the optional center hub that fits the ppg input.

That's good to know, cheers! What does it drive like?

I'm really liking this getrag idea. Does anyone know what tail shaft to use with the Getrag in a 33? I know you use the R34 front shaft but not sure on the rear. I'm assuming the 34 unit also?

      Duncan's V37.......race car?

      Even more fun, leave all the ADAS stuff plugged in, but in different locations, hopefully avoid any codes!   And honestly, all these new cars with their weird electronics. Pull all the electronics out Duncan, and just shove an aftermarket ECU and if needed a trans controller in, along with a PDM. Make it run basic but race car styled!

      To follow up a question from earlier too since I had the front bar off again (fking!) This is what is between the bumper and the drivers side wheel And this is the navigator side, only one thing but its a biggy! So basically....no putting coolers in the wheel arches without a lot of moving other stuff. Assuming I move to properly race prepping this car I'll take that job on and see how the computers respond to removing a whole bunch of ADAS modules

      Duncan's V37.......race car?

      By Duncan · Posted

      So I prepped the car for another track day on Wednesday (will be interesting to see coolant temps post flushing out and the larger reservoir, with a forecast of 3-14 being 20o cooler than last time I took it out). Couple of things to mention; since I am just driving the car and not taking a support vehicle, I took the rear seats out and just loaded the back up Team Trackday style. Look at all that space! To cover off removing the rear seat....it is weird (note the hybrid is probably different because it wouldn't have folding rear seats) Basically, you remove the lower seat base, very similar to a r series but it is a clip that pulls forward to release the base rather than it being bolted down. Easy Then, you need to remove the side section of the rear seat on each side. There is a 14mm head nut at the bottom of the side piece, the it slides upwards off a hook at the top to release; you also need to unhook the seatbelt from the loop at the top. Then the centre piece is weird. You need to release/fold the seats forward with the tab in the boot on each side From there, there are 2,x12mm headed bolts holding the rear of each seat to the folding bracket, under the trim between the rear seat and the boot (4x christmas tree clips there, they suck). The seat is out but you can see where the bolts attach to the bracket

      As discussed in the previous post, the bushes in the 110 needed replacing. I took this opportunity to replace the castor bushes, the front lower control arm, lower the car and get the alignment dialled in with new tyres. I took it down to Alignment Motorsports on the GC to get this work done and also get more out of the Shockworks as I felt like I wasn't getting the full use out of them.  To cut a very long story short, it ended up being the case the passenger side castor arm wouldn't accept the brand new bush as the sleeve had worn badly enough to the point you could push the new bush in by hand and completely through. Trying a pair of TRD bushes didn't fix the issue either (I had originally gone with Hardrace bushes). We needed to urgently source another castor arm, and thankfully this was sourced and the guys at the shop worked on my car until 7pm on a Saturday to get everything done. The car rides a lot nicer now with the suspension dialled in properly. Lowered the car a little as well to suit the lower profile front tyres, and just bring the car down generally. Eternally thankful for the guys down at the shop to get the car sorted, we both pulled big favours from our contacts to get it done on the Saturday.  Also plugged in the new Stedi foglights into the S15, and even from a quick test in the garage I'm keen to see how they look out on the road. I had some concerns about the length of the LED body and whether it'd fit in the foglight housing but it's fine.  I've got a small window coming up next month where I'll likely get a little paint work done on the 110 to remove the rear wing, add a boot wing and roof wing, get the side skirt fixed up and colour match the little panel on the tail lights so that I can install some badges that I've kept in storage. I'm also tempted to put in a new pair of headlights on the 110.  Until then, here's some more pictures from Easter this year.

      I would put a fuel pressure gauge between the filter and the fuel rail, see if it's maintaining good fuel pressure at idle going up to the point when it stalls. Do you see any strange behavior in commanded fuel leading up to the point when it stalls? You might have to start going through the service manual and doing a long list of sensor tests if it's not the fuel system for whatever reason.
