Yeah I was skeptical about the diff as well, but not having had any experience with FWDs I thought id give it a go, and boy did it make a difference; like night and day.

The control coilovers are quite soft so the car loved to bake the inside wheel on exits out of tight corners no matter what I did. With a welded diff you are able to use the power to pull the car around the corner, its truly incredible. The fact that its welded doesnt even really affect entry so long as the suspension is set up right with driving style to suit.

I could have fitted an LSD ($1000+ from US) but for the money I dont think I need to try it, and the car is already fast. Welding the diff was worth over 2 seconds at Winton with nothing else done.

Do they weld diffs in Excels too?

PIARC weekend was fun. Next time out we'll be racing together at the Winton 300 rather than against each other.

Yep, me. Been running since the start of the season and ive never had more fun in a car! (The GTR is a different beast, I still love it). It is a serious amount of fun with grids as large as 23 (I t

Correct.Only standard rebuild tolerance is accepted. You can bore 0.6mm out the block. You can take 0.25mm off the head. But the compression has to be with a specified range. It's all in the regs.

So the weekend went good , I had a blast! Got nails hard in the rear. Bloke behind me had no brakes at the end of the straight at Symons plains his left brake nipple wasn't right and this was the end result,post-134876-14409273236901_thumb.jpg

But if bad luck but it's all good I guess that's racing, bring on the next round [emoji106]

That sucks. Id be pretty annoyed if someone did that to my car - thats bad racing imo. And wont be cheap as you cant just unbolt the rear quarter to put another one on!

Each driver has a responsibility to race safely, but obviously staying close to you to try and pick up a position was more important to him and as a result plowed into you.

It is however an entry level category like PC so its no surprise :-(

i know a few people in the pulsar challenge, put up a pic of your car matt!

its interesting that most people opt for N14's due to price and independent rear suspension, but often the top of the field are N15's. bit of tweaking to the beam and they handle well.

and yeah, lots of people saying good things about the welded diffs. Mfactory release a helical diff last year which is around $700usd and the other option is discontinued Nismo which can fetch around $1500 secondhand

anyone here running in Pulsar Challenge?

Apparently you can build one for around $5000 and race meets should set you back around $500 a round. was thinking of splitting the cost with a mate and running the enduros with him.

keen to hear people's experience with them!

Damn... that's actually really cheap. Way, way cheaper than I thought. I need to look into this!

edit: apparently you can bore out the engines and such. that would tend to increase the cost, lol. what % of competitors have done this ? how do they enforce some of the other restrictions on internals?

What? You sure? Very little modification is allowed.

      Steps to DIY sanding car back ready for respray....

      By silviaz · Posted

      I am probably calling this too early but I think I found what part of my problem is. I have a couple of dents that are fairly close to each other and I tried to fix them individually. Recently I put one larger coat across all the dents and sanded it and for the first time ever it's all even except for the edge where the bare metal is, I just need to put some putty there. I'm ordering some better longer blocks that are more flexible. Other good news is that the other repairs on my panel are flat even with the guidecoat. It's these 2 dents which are an absolute c*nt l lol.

      Murray will have better input, but I'd be going with less filler, and aimed at the low spots mainly, and hence won't need as much sanding, which then means get the guide coat on earlier. That's how I'd do it, BUT, I'm not a pro, I'm a DIY hack who will then get the shits halfway through, and have one spot awesomely repaired, and the other spots look like a 3 year old was left unsupervised with workshop tools...

      GTX2867R GEN 2 NO OUTPUT FOR BOOST SOLENOID

      Where is the most common place to locate it? Disappointing that Garrett won’t make a fitting for it since they know everyone will use it

      R32 GTR Limp Mode?

      By GTSBoy · Posted

      A HICAS fault really should not cause the engine to go into limp mode. These cars are so old that the systems barely talk to one another. The thump might be the lockoff solenoid valve for the HICAS (the safety valve) getting closed, to lock the rear wheels "straight". I say "straight", because when my HICAS used to shit itself before I took off and nuked it from orbit, it would lock up with the rear wheels wildy non-straight and you'd need 45° of steering wheel to drive straight. Take off and nuke it from orbit. First step is to pull the smaller of the two plugs out of the HICAS CU. See if it stops misbehaving. You can also (whilst leaving it plugged in) try to get the HICAS CU into diagnostic mode by doing the pedal dance, or by connecting a CONSULT capable diagnostic reader into the car and seeing what it has to say for itself. Can't do either of these with it unplugged though. 1st gen HICAS is a ballache. I would do a complete delete. I did do a complete delete.
