How do u know what time u get? does someone have a stop watch or do you need to bring a lap counter along?

Thanks Luke

If there is official timing they give you a little box to cable tie to your car somewhere

If its not official timing..can use lap times, or a stop watch or ur mobile phone

ax & sinful, you actually both have a legitimate point. There's no doubt that oil surge is a crank journal's worst enemy but having said that, its a matter of working out how much over fill is too much. As long as the crank couterweights aren't swimming in the stuff you should be fine, on the other hand if your crank is hitting the oil on every rev, you're asking for a major disaster.

The only safe & sure measure is to do it the right way the first time......deeper & larger capacity baffled sump and oil restrictors with a good catch can.....problem solved.

Plus it's cheaper to do it right the first time......speak to some of the boys that have broken bottom ends due to surge or over fill.

SLED they must of over filled quite alot :) But I do agree with you on the deeper larger sump and baffling...I am actually baffling my car over the Easter break.. Will be a nice surprise if it already is :P

I do have a catch can and only ever overfill a litre and half and have no problems..That's all I am stating and it works well for me :)

I'm only trying to put across that you dont have to have your car massivly set up to get out and drive on a track..Which I think is alot of peoples mind set..

Cant wait to see SAU SA have there first Track day and I wished this was happening when I live there..

CORRECT. I'd be curious to find out if over filling the sump puts more oil in the catch can than a STD fill after a couple of hard laps or if the difference is negligible.

I've only had my GTR for approx 4 mths so I haven't been able to test for myself.

i know about rod destruction due to too much oil (hydraulicsrod destruction, is the correct term)as i have worked on aircraft engines before and seen what too much oil does to them i would say there wouldn't be much difference to an rb26! do it properly and dont risk bending a rod on a perfectly good motor! i have a 32 with 310kw and i dont have abaffle thats why i didnt take it out to lala, i am also in the process of building an n1 motor with gtrs turbos with a real n1 block, till then my 32 wont go near the track! i hear what your saying but that seems too risky for me.

Well I have enclosed catch can on top of my engine from Just Jap..

Yes it will and this is why we baffle and overfill so there is still something left in the sump to pick up. I have seen the catch cans with the breathers, and they do leak once you get your oil temps really really hot..We have two GTRs and in the other one it's baffle and has loads more power then miine and we overfill that with a litre and half still and its fine :blink: and he has done 2 Trackdays with that freshly built motor..

I am sorry you do have a good point with what you are saying but that is with excessive overfilling (like 3litres due to the pressure and the oil having no where to go)

My GTR is running the same amount of power as you and I am not risking my motor with over filling just a litre and half its been proven in 3 track days now and pushing the car exceptionally hard! Its happy

      Would be good in your car I reckon Johnny. Have seen reports they don't seem to love circuit use and sustained high RPM, but there's so many variables and implementations it's hard to tell fact from fiction.  All that said, is it worth it in this car given how you feel about it? Probs not?

      R34 GTR Front Diffuser/Guard Liner questions.

      By Duncan · Posted

      I don't know specifically. I *do* know that it is very likely that historically most/all undertray replacements remove the inner liners and people just run without them. When you are hectic (or serious) enough to really want/need a different undertray, you are probably also running wider, taller or different offset wheels and the guard liners are the first thing that rub (or as I said in the other thread, they blow out at high speeds anyway) Of course, that is before the pricing went nuts on R34s, nowdays it is much more likely people want/expect to retain the liners to protect their overall investment

      Haven’t had a chance to drive it properly yet. It was rwd and pissing down rain when I drove it home and now it’s in the air with the so I can change the oil. Going to do the  gearbox oil while I’m at it as well, may even do the diffs

      R32 GTS (RB20DE) Injectors Replacement

      By GabsReDeal · Posted

      On 12th June, the mechanic could not figure out what the issue was, but the car seems to be flooding with fuel. He was suspecting the tune, thus referred me to a tuner. Although the tuner is not familiar with Nistune, last Monday (30th June), he came over to try and re-map it. Despite the tuner trying to completely stop fuel, it kept sounding like it was pushing fuel. Tuner ended up suspecting either the ECU or Injectors. I do not believe the ECU or Nistune is the issue, as the Nistune software reads and communicates properly. Today, I removed the (new) injectors to see if they are clogged or leaking. Surprisingly enough, after those 3 days of driving, injectors 2 and 3 look very blocked. You can see the difference in the picture. I blew a bit on 3, that is why it doesn't look as clogged as 2. I am still unsure if this is what is causing the no start issue, but I am now feeling that I may have bought the injectors and Nistune without the need to do so, as the problem seems to be coming from somewhere else.
