I know how you guys like pictures :cheers:

The blue one is the hydraulic profile I grind on and the red one is your GTR cam. This graph is what is on the camshaft. You can see what needs to be taken off. The little closing ramp on the blue one demonstrates a very good hydraulic profile made by nissan to prevent fast valve seating and potentially necking the valves.

This one is to give you an idea of what happens at the valve. The red (GTR) profile is smaller because it has had some clearance taken off it. So you can see the gains to be had from this grind. I don't have a GTS grind on the cam doctor (or couldn't be stuffed finding it) but rest assured it is quite a bit smaller again.

Wacol. 4076 Q.

Put a note in there saying what you want along with your details and attention it to me. (Just a general rule for anyonw who wants to do it)

is that near st lucia? 4076 was my new postcode i thought...

Luke, I've been slack and not on for a couple of days but will hopefully get them away today.

Ivan Tighe's huh, had some cam work done there before when it was near the city. Very impressed with the rep and the work done.

As for Qld, give me ummm ......3.5 months and Vic can go to hell, or antarctica, whichever is closest. ;)

    • Drain it. I got official Matic D but you can get whatever is listed as Matic D compatible.
    • Thanks guys,  Yeah I should at least have them dynoed, at least then I know what I've got as a starting point.  The springs on these are hard as rocks. I vaguely remember Russman saying he was going to sell the shocks to me with the rocks fitted, as he was keeping the softer springs for his new setup.  I didn't click at the time but of course that was to let me know the shock/spring wouldn't be matched.  I also remember pricing up new springs around 2014-15, but, house, money etc. it never happened. So that was another reason to have them rebuilt. I have rebuilt the forks on many motorcycles so I think I could handle the seals on these easily enough, but getting the valving right would be a rabbit hole I cbf exploring.  Duncan, interesting to hear RP was tuning these back then. I might give them a call.  In the mean time I have been busy fitting sway bars. The Whiteline rear sway bar I purchased 15 years ago finally got fitted, along with the Whiteline front bar that showed up last week. Just waiting on new links for the front sway bar to finish that off.  And my spare set of advan AVS VS5's should be back from the powder coaters in a Pearl White finish sometime this week, with a set of Hankook RS4's lined up for fitting.  And then I just have all the suspension bushes to do. A comprehensive kit is on the way... Lots to do before the Ararat hill climb. Cheers guys 🍻   
    • Nice car! I’m glad folks in the US have gotten past the FnF and are buying real cool cars like the 260RS I was with a bunch of mates in Portland about a year ago and spotted a green Stagea (just a regular 2.5T AWD) parked about 2 blocks away and they were like “a what?” So I made a bet with them for a round of beers and said “ok one of you run down there and tell me if the steering wheel is on the correct side” 5 mins later the American comes trudging back up the hill and goes “he’s right guys. Ok what beer do you want?”
    • Should replace OR drop the tank, give it's good clean. Might be worth replacing that entire fuel level/pump/cradle thing with this: https://frenchysperformancegarage.com/products/fpg-s13-180sx-r32gtst-single-pump-hanger-kit-billet-hat-6-v3-fpg-089?gQT=2
