Brendan , unless you are going to constantly drag race the thing , go with Autoclutch and there 9 plate sprung brass button with slightly upgraded pressure plate.

Have fitted it to 3 x GTR's and 1 300ZXTT with no prob.

Micko , rhino and Boosted RB26 have them in there GTR's and Rhino did a 12.4 with his from an off the limiter launch.

Price for BoostedRB26 last week was $800 ish fitted and took one day.

Twin plates are good but rebuilds are expensive .

Cheers

I have a nismo twin plate and it's fine to drive. Before that i had a 5 puck ceramic single and it wasn't any different to drive. Both weren't very easy to drive but were quite manageable on daily basis.

My advice would be to go for a twin plate, your wife will get used to it. It will be a pain for her compared to other cars she may drive, but unless you put back in an organic-full faced stock clutch in there, all others will be as well.

Thanks Emre, I must also point out that once the engine has been rebuilt it will easily be putting out over 350rwhp considering it put down 302rwhp at only 0.75 bar but was running out of air and fuel (now solved with purchase of 660cc injectors and z32 afms). Would a rebuilt standard be able to handle this sort of power and more knowing I will be taking it down to the drags once in a blue moon.

You should have no problems if it's done properly to the factory specifications or better. 350 hp at the wheels is well within limits of the stock bottom end.

To answer your previous question, if you go for a twin plate a lightened flywheel will come with it, do not lighten that any further. If you decide to go for a single plate you can choose to lighten and balance your factory flywheel, just don't take any more than %25 out.

In fact, re-reading your last couple of post i would urge you to go for the twin plate. For a single plate clutch to hold onto 350hp+ it would have to have a lot less surface area and a very heavy(on the foot) pressure plate unless the pivot point of the fork is altered. Result would be a no more friendly setup than a twin plate that can handle 700hp at the flywheel.

A lightened flywheel will help you accelerate quicker. The mass of a twin plate assembly is naturally more than a single plate, so they compensate it with a lightened flywheel already. In my case, it was still slightly lighter than my single plate setup.

Well ladies and gents, we've made a decision on what clutch we're going with. Thanks to Paul and Brett for lending us the keys to the rides for a test of two twin-plate clutches. Paul's has an OS-Giken in it and it was rather easy to control, partly attributed to the power-assisted clutch in the Skyline. I was half comparing to the standard GT-R clutch, and the RG clutch in the Silvia and it came in about half way. Brett's clutch is an unknown twin at this point, and was pretty much close to a standard feel. All in all the wife was pretty happy with the decision to go the twin plate OS-Giken. Thanks again for all the comments.

Cheers

Brendan

      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?

      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.

      R32 GTS (RB20DE) Injectors Replacement

      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.
