Hey all.

I've heard conflicting (annecdotal) evidence 'bout both high flow sumps with "windage" trays and injectors.I know one V.nice R32 GTR in our area that has an aftermarket sump(brand?I can't remember)that had problems with the physical depth of the thing grounding out.Others have a rep' for having the baffles that'll only work in a straight line(i.e.:drag racing).I need extra capacity and baffles to stop oil starvation for track use...any ideas?

Equally,I'm looking at putting injectors of the 700cc range.I hear from various trustworthy sources that my Power FC wont like certain types of injectors(Sard comes to mind-something about weird impedence rates?)...Likewise:any info'?

With regards to sump baffling, why do you need an oversized sump? A standard sump will hold 5 1/2 litres comfortably and with the Tomei baffles and oil restrictors, I have never heard of a car going pop. Im still not 100% sure on why people need increased sump capacity...

As for injectors, the Sard 700cc's are a little 'wierd' to work out, but Ed is getting there with them, and once he finishes sussing them out on mine he should have the settings ready to punch straight into yours. The problem lies mainly with injector lag time, they lag a little more than Sard claim they do.

The idea behind more "litre-age" is the oil "works" less,therefore stays cooler...plus there's a greater volume in the sump at any given time,therefore less likely to "run dry" momentarily...I'll be running an oil cooler,too,so I'm just covering all bases.Don't want to fork out for a second rebuild!

I guess I'll owe you beers/favours,being that your car is being the test mule when it comes to injectors!So you're thinking the Sards will be OK?

This topic has been covered many times in the Forced Induction Performance forum.

Some of my posts from there follow;

The Trust kit for GTR's is very simple, it extends the sump downwards (reduces ground clearance) and has an extended pick up and a cylindrical baffle. It increases oil capacity by ~1.25 litres. The Performance Metalcraft sump we use has wings (so it does not reduce ground clearance) out both sides with one way doors and baffles. It does not need an extended pick up. It increases oil capacity by a bit over 2 litres.

In funtion there is really no comparison, a winged and baffled sump is by far a superior solution.

---------------------------------

Question about fitting, engine out or not

It takes about the same amount of time to do it in the car, but there are no complications or risks. It is pretty hard to get the wiring wrong or damage the clutch if you don't take them out. I strongly suggest you jack up the car and have a look for yourself. Basically everything under and/or attached to the sump unbolts, so you remove all that stuff and there is easy access to the sump itself.

My suggestion is to have a chat to a few of your local workshops.

--------------------------------------------------------

A larger sump is not a substitute for an oil cooler on the circuit, it doesn't matter how much oil you have in the sump, it will eventuially heat up. My personal recommendation is that an engine oil cooler is a must on ANY GTR that sees the circuit.

--------------------------------

Try www.hioctaneracing.com.au if the Performance Metalcraft site doesn't work, same people.

Hope that helps :(

The Sards are going ok in mine, havnt had any major problems with them. Even on 22psi (the highest boost I will take them on standard pump fuel) ed has them setup good enough that they never see over 80% duty cycle. This will be reduced a little more as we work them out 100%, id say we've got them 90% worked out.

Ill also have to take you for another drive as the camshafts arrived today and should be going in tomorrow (along with the dreaded hks twin plate, so no laughing when i continually stall the car :()

Who tuned your car meshmesh? Everyone I spoke to, including some high profile sydney tuners all said Sard 700cc's were a bastard to get working properly

Got it all done at ICE Performance.. the only "minor" hickup which I can think of, was a "starting" issue, but was solved very quickly with a new more powerfull battery, sealing the connectors on the bosch pump (though a relay would have been better), and Nigel did some of his magic tuning with the Power FC for the injectors... But all was fixed, and nothing whatsoever was an issue, infact SAU member markr34gtr has SARD 700cc injectors in his 34GTR and at the moment he's pumping over 400kw at the wheels.

Maybe have a chat to Nigel at ICE or markr34gtr.

Amaru & LTS..

That's the first I've heard anything about the SARD injectors?? We had the 700cc SARD's on our GTR, with the Power FC, bosch 044 pump, HKS GT2530's etc etc.. never had a problem.

Hi Meshmesh.

EXACTLY what I wanted to hear:that set up is where my car is heading...

Ah,Grasshopper!One is very curious of the results when one speaks of these mythical beings:"camshafts",you call them?!Y

Yeah-keen to see what a difference they'll make:should be VERY noticable,from what I hear...And don't panic about the twin plate:you can get your own back laughing at my a** once mine has the triple plate AP Racing fitted up...

      NC MX5

      It's kind of interesting - They definitely do builds that split the difference between what they like and what will generate views and engagement. The NC Platform always surprises everyone in a good way, in an uncomfortably good way some may say. They could throw a LS in there and arguably have the best (and best performing) car of the entire stable. But that isn't necessarily what draws views, because people viewing don't want to accept the vegetables of a LS NC MX5 being a superior vehicle in every way (including fun) than a RB26 240Z. This is also why there's not a lot of content about the GR Yaris (on the web in general). They're too good, yet 'only a Yaris' The community doesn't want certain cars to be as good as they are - to beat their hero cars, and I believe the NC MX5 is absolutely one of those cars.

      R34 GTT Central Locking Pains

      Yeah - My key still does the chime thing. I followed the procedure but it didn't activate on the (identical) third set of keyfob that I had. I vaguely remember the alarm saying you can only pair two keys with it. Now that I've dug it up, it appears that you very much can pair keyfobs to the alarm system. (which are the fobs I use to unlock the car). I have successfully diverted the thread and can probably not use the OEM keyfob ever again unless I use the aftermarket alarm and attempt to pair the OEM keyfob to it. Which might just work, or not :D. I definitely used the nissan method and not the aftermarket alarm method.

      What makes it worse is that Nissan made keys in the same style, for example R34 and Stagea, but they work at different frequencies or something like that. So they look the same but the remotes are not interchangeable. I learned that from some guy selling aftermarket blank keys.

      Does your door chime work when you have the key in the lock and open the door? I've had that disabled because it's f**king annoying and it is one thing that messes with the pairing. Because now the car doesn't detect key in ignition anymore and the slide-key-in-and-out sequence does not trigger the pairing mode anymore. The service manual has a section on the various bits involved in doing the syncing. I presume it'll be similar between Stagea and R34.

      Agree, but meh, I think is is based more on LOLS than actually apples to apples, like, who would have thunk a turbo 4 cylinder would not beat a NA 4 cylinder  I think with just basic N/A mods, like a exhaust and tune, it would be equal to the Mini in its current form, maybe I know my current 2.5 would "chop the mini" as the midrange now has a night and day difference in power delivery compared to the tuned 2.0, by around 20kwatw and 30nm from around 2k rpm "ish"....... I'm kinda hoping that they do a N/A build, either with the MZR 2.0 or with whatever they decide to use If I recall correctly they did talk about K swapping one a while ago
