Fixed! haha- aint no AWD-style understeering shenanigans here!

Wow did i mishear that? not inconceivable with all the engine noise and tyre screeching :P

oh and love your work Eric, pretty smooth and very atypical of a yank to downplay their work "oh btw heres a few random pics" and then bust out some of the most awesome pics i have ever seen from a track day.

Marulan is especially hard to get good shots from unless your prepared to go bush and hit some of the far corners of the track, you got some great shots of Skylines doing what they were made to do. Looks like there is a 33gtst s2 just like mine there too, at least on the dry day that you went?

Never driven there in the wet but had a few wakefield days while it was raining and for all the fun i find it far too unpredictable (and im not the only as evidenced by your blooper reel) whereas on a dry track you can really hone your skills and find out what the car is capable of.

Thanks for the heel and toe lessons but nothing beats practice, practice practice!

Also, further to Duncan's post, learning to correctly heel-and-toe early before you get into a corner will help with engine braking, taking some of the pressure (and therefore heat) off your brakes.

I find i like to use the extra engine braking caused by the spin up of the motor when i don't heel/toe (of course easing the clutch out so avoiding compression lockup of the rears) and I still get the regular engine braking you're talking about from the closed throttle.

I guess the only way to interpret this however, is that my brakes are too front biased, because I reckon my way of doing it gives me better overall stopping. If the brakes were better balanced the non-heal/toe would cause compression lockup on the rears.

Yep, wrong way around Dave, original post fixed ;)

Jarrad, almost certainly that noise is your gearbox thrust bearing. A bit of noise from it is no issue, just replace it when you get the clutch done. It may have been brought on by the day but it isn't urgent to address.

Adam, spot on, if you are using compression braking and find it helpful, you should have more rear brake bias. It's really just a bandaid for something wrong in the barke bias (because a foot brake will always be more effective and consistent)

BTW Eric....always have 2 hands on the wheels when you are planning a spin :P

is that expensive duncan??

pretty much determining weather to join the wakefeild day on how much itll cost to fix it.

You don't fix it until the clutch dies.

Most R32 and R33s have the same noise, just keep driving until you need a new clutch itself.

The GTR lives!

just got it back from CRD about 10 minutes ago and proceeded to drive it very sensibly with out any sort of erratic or unnecessarily vigorous acceleration all the way home causing very little noise pollution in my neighbourhood. Or the exact opposite of that, I'm a little hazy on the details.

Apparently it blew one of the boost pipes off and just blind sided the ecu's ability to tell how much air was actually going into the engine, hence the epic over fuel.

Anyway, good to go for the next track day!

great news Matt...you owe me a proper ride in that beast! Seriously, the flames coming out of the exhaust when i followed you in to Picton were epic

      Well, this is probably where a wiring diagram and a multimeter come into play.

      gauge needle removal

      By Jarsky · Posted

      I can say to anyone thats doing this; having done a number of R clusters; just be careful if its an unknown cluster.  It takes a bit of force to pull up; but if it feels excessive then its probably stuck. I've had this and pulled the entire hair spring out; and I can tell you; its not easy getting the correct spring replacement with the correct inner diameter and winding. In my case someone had used some sort of adhesive to stick it to the spindle and it pulled the whole spindle out; which the force seperated the hairspring from the spindal and caused it to deform.  You may have to clean it (IPA); or in my case if i'd known i should have used some sort of solvent on it.  Also check out Cruizin Central on eBay. He does all sorts of dials; and you can email him with any custom designs you want. So if you want like certain logos etc...he'll send you a mock of what it will look like then you accept the order and he'll take care of the rest. Fantastic dials and he can do basically any design you want.

      R33 GTST Axles

      Have you confirmed its the actual axles? Also the wheel bearings that mount on the hubs to hold the axles wear out. I replaced mine as they got play in them. It sorted my play issue.

      R34 Speedo not working after manual swap

      By Jarsky · Posted

      Ive converted a few clusters for the R33 with 320km/h dials. On the back there are some pads which can be bridged or unbridged (using solder or wick braid) to calibrate it. There is one bridge which is for MPH <> KPH; and there are combinations of bridges to offset it. There is probably a diagram  For example; this is my conversion for a 180km/h dial to a 320km/h dial (I put custom GT-R dials on it with the GTS25t layout) If you have J2 soldered (assuming the S clusters have a similar config to the R clusters); you may need to remove that solder

      Back on topic 😉, these are some of the notable pages from the booklets that are supplied with each weekly parts update. I never knew the BNR32 test mule car had an S13 Silvia front end... *Edit: On closer inspection the test car still had the R32 body, but only the front end had Silvia panels etc.
