Yes - but only 9 PSI ( on a 3040)

Boost won't hurt your run in as long as it's controlled and gradual - Load is good for run in - as long as it is controlled - like I said.

Stay away from constant revs during run in ! Change gears a lot

first 500 kms of my new motor...

Rings were bedded in on the Dyno. Dunno whats involed there exactly. So i wont comment much.

Then 10psi the day after it was tuned, till i changed my gate spring 2 days later...

Few dramas, sorted em out after about 100km's it was up @ 16psi ~270rwkw...

Definately saw rev-limiter here and there by mistake as it gets there fast lol.

Then my turbo died... my fault it seems from the past days on the old motor where it got some rough treatment :Oops:

So ive done 500kms now, and a a good 20-30 dyno runs on 16psi/270rwkw

Once the turbo is back in in a few weeks and then 18-20psi out of a Garrett GT30

My engine builder said the rings bed in almost straight away.. and that as long as you don't screw the car for the first while, and use the right run in oil, it's fail proof :rolleyes:

He said most engine shops say 1000k or more, as by the time you get to that many k's you have forgotten about blaming them for anything. lol

my mate had his new motor run in on the dyno, the mechanic ran the motor lean so that the rings would heat up and bed in quickly and that was it! Started doing power runs!

Sounds like a good idea to me, running in a new motor on the street dosn't make much sense when u can do it in 5mins by controlling the fuel, idnition and load on a dyno.

      gauge needle removal

      By GTSBoy · Posted

      Yeah, so widen your search to any Nissan speedo first, then go wider if needed. I will say though, that there is a better than even chance that what I said first will likely come into play. They quite possibly won't come apart without damage. I tried to disassemble a stepper gauge that I wanted to repair. There was no way that needle was coming off the spindle, and I could not see how the spindle would come out of the mechanism behind. Assembled once, never to be disassembled, was my conclusion. Could be the same on the R34 cluster. Failing that - take the cluster to a workshop that specialises in automotive instrument work. There's usually at least one in every Australian city. They'll either be able to do it for you for small cost, or tell you it can't be done. It might be that "it can't be done" unless you follow some arcane procedure, including trickiness to glue it back together or something, that only experienced techs know.

      R-chassis INNER tie rod torque spec?

      By GTSBoy · Posted

      Well, given that I, an engineer, almost never bring out the torque wrench to tighten up chassis bolts, despite fully knowing the theory, and instead rely on feel, which I happen to know is exactly how the majority of mechanics do things, should tell you the level of actual peril that exists from not achieving exactly 88 Nm of torque. How about if I just say then that 88Nm is at the lower end of the correct wheel nut torque range? Everyone knows how to tighten a wheel nut, right? And almost no-one ever brings out the torque wrench for that task

      Don't be ridiculous. "2-3 ugga duggas or one Oof. You have to use Oof on tie rods because you can't get an ugga dugga on there." Is not helping the guy at all.

      gauge needle removal

      By JC71 · Posted

      I have done a lot of research before posting here and on gtruk forum. couldn't find anything. I have my gauges all part except the needle itself. the needle has a extremely small hole in the center, but the shaft going to the needle is extremely small and appears to have nothing to index it either. doesn't seem strong enough to simple pry or pull without damaging something. Already tried the old spoon trick on a extra triple meter I have from a gtt, but no luck. the center cap comes off easily but the hole in the meter face plate aren't big enough to get over the needle itself. figured this would be my best place to find someone who might have actually removed theirs. wonder if there is some type of small pin press tool to push the pin in while pulling the needle base off.

      Ok...its taking me long enough to finally do this.  Feck financial security...heart disease will get me soon enough anyway So welcome to the garage..."Clem" Belsil80 has been running a 370Z in Super TT series. So after entering with him in last years Winton 300 i figured I  need my own car. Seems SAU Vic race cars need to be yellow....{tick} Reckon with enough motor i will be able to make up for the lack of talent and stay ahead of the 370Z... but the LS powered S13 and E36s are a ways up the road Aim is to have a car that doesnt stop or turn but has a bit of shed built motor with jam...maybe some cream  First step is getting this ex drift car log booked I am keeping faithful silver car. As the road-club car gets upgrades the race car wil get the sloppy seconds
