Finally results are in.

She punched out 200.2 ATW on 12 psi (although spiking to 12.8) Not bad. But useless.

As soon as i took it out on the street off the dyno and gave it some... Rattling noise. Ping im sure. The 'tuner' was with me at the time, and looked concerned when i stated hey its f**king pinging hard.. he wound back the boost a little and f**ked with the timing.

Still did it at around 11.8psi. He stated you need a decent intercooler... Drove it tonight briefly on the high setting and it didnt ping (very cold out tonight), but it comes on boost in an unstable manner. the dyno readout is pretty wobbly and has a dip higher in the revs. Ill post this when i can. Looks like shit to me. With the standard solenoid grounded permanently it pulled 182kW ATF 9psi and a nice flat curve.. With the Eboost on 12psi its wobbly and looks like shit.

The boost controller is a new Turbosmart EBoost Street. Ive been reading the manuals and its states various options regarding gate pressure and sensitivity. Im sure these could be improved as it spikes considerably. I thought these f**king electronic things didnt spike once set properly.

Seems i now have little to no faith in his abilities or advise so im forced to have it retuned by someone who is trustworthy because i cannot comfortably drive it again without freaking out. Its now set back to setting one with runs around 9psi.

Can anyone please a reputable tuner in Sydney??? I dont care what it costs as long as they know skylines!!! Desperately need some decent advise i dunno who to listen to now

This sucks as this car was absolutely perfect prior and its disappointing to be honest. Its impressed everyone whose worked on it... Im now contemplating ripping it all out and replacing it with the factory setup as before running high mode constantly... Atleast i could rev it and not worry about destroying the motor.... Surely i could run 10-11 psi with a r34 SMIC without troubles??

Current mods

R34 SMIC

3 inch Nismo exhaust

JJR Split Dump/Front

K&N High Flow Panel

Turbosmart EBoost Street....

Cheers,

Matt

does it have an aftermarket ecu or are they just advancing the timing via the CAS?

Standard ecu. I wouldnt have a clue as to what you would do if you were adjusting timing (im mechanically impaired). I heard him mumble it, open the bonnet and adjust something at the front of the motor?

You pulled 200kw@wheels on the stock ECU and a side mount :blush:

The stock ECU should be dumping bulk fuel, how the hell is it pinging?

Adjusting the timing via the CAS is pretty bloody dodgy.

+1

You need a decent fmic or a bigger side mount, also what are your plug gaps, at that boost level should be 0.8 or 0.9mm

no need to reduce the plug gaps, if your coils are good you can (and i do) run 1.1mm all day every day with any sort of power the stock turbo can give you.

To a point of course, i hit 18psi with my standard turbo and it was breaking down, i now have a hi flow and any more than .85bar and it starts to break down.

ive never heard pinging before. it was an obvious metallic rattling at revs under load. But the AFR's showed at high revs around 10.5 : 1. Its got me f**ked i just dont understand it enough to get my head around whats happening.

People are running in excess of 200AWKW with an R34 smic - that's not the problem. You need some way of tuning the motor and just playing with the cas doesn't count.

If you can't afford a Vipec get an SAFC and an SITC and get them tuned on a dyno.

Contact Anthony (Guilt Toy) for a tune and the lowdown on your options (may be others in your area but I wouldn't know).

Another point is that you should never hear pinging with a standard r33 ecu as when ever the knock sensors pick up knocking (usually it is very conservative) it will retard it.

the sound of knocking, its fairly loud? could be heard over the motor revving? this was

is the engine light flashing when the "noise" occurs? if its detonation, and you can hear it whilst driving, inside the car, surely the engine light will be flashing.

its not something silly like being able to hear the EBC solenoid ?

if its detonating, and the engine light is not flashing, maybe check the ecu and see if it has been attacked. maybe its been fiddled with

is you rev limiter at 6800 or 6900 or what ever the stock limter is? what about speed limiter?

i know my car a few year back on the std ecu, anything over 10 psi, Rich & retard would chime in, and it would run like a fat kid through sand.

I didnt notice the engine light. I generally notice and hear every noise and rattle. i dont think ive ever revved it to the limiter. it revved to nearly 7 on the dyno but i didnt hear a limiter. The rattle noise also appeared a little lower in the revs around 4-5 k...

It shows on dyno sheet AFR running down to mid 10's which is apparently rich as hell. my piss weak understanding tells me it shouldnt knock if thats the case? One thing is certain on high mode last night it spikes up to atleast 13 or more. On the low setting it doesnt spike at all. After reading the EBC manual i think i can adjust this with gate pressure etc so it doesnt come on boost as quick etc??

Ill pay anyone who is genuinly capable in there trade and has a good knowledge of skylines. Im tired of pretenders, as this EBC wasnt cheap including the dyno run/tune which was useless as tits on a bull.... what good is 200 ATW if you cant use it safely

    • This looks great! Awesome to have the 5 speed with an LSD in this. The Recaro's look like SR2's or SR3's. It's a shame they've been retrimmed as they would have looked sweet in their original colours. I think I'd want my agent to be a little more up front and informative too. I've never imported but I reckon it would make me a little nervous, so the more info the better.
    • Thanks for doing that Duncan! Makes you a good person in my books. We don't get kangaroos or wombats here. But we have bats and it's similar. AFAIK it's often the mums with a baby attached that get hit because they drop lower when starting from a tree. If you hit an animal, check on it. https://www.ifaw.org/au/resources/wildlife-rescue-app An app to get the closest wildlife rescue contact.
    • My dream is also to have a proper hoist, but I don't think it will ever happen. My quickjack is probably as close as I'll ever get, it really is very good though. 
    • Yeah we keep on in the dailies, it is pretty poor how many animals get hit and the driver leaves without checking....have saved a couple of little ones over the years. Bit of a gruesome job though, pouches generally need to be cut open because they are so tight and often the joey doesn't realise mum is gone so they are still locked onto the teat. I checked the modules in front of the DS wheel where an oil cooler should go.... There is the radar unit - that can go for race use) One of the 2 HX water pumps, the silver cylinder. That needs to be kept but might be able to be relocated But the bad news, the big computer mounted vertically in front of the wheel (blocking any potential air exit) is the electric steering computer. That is required until/unless i do a hydraulic steering conversion, and in CAD based modern car design it is not like I can just pop a big unit like that somewhere else (plus the loom would be too short anywhere else too). So, the passenger side is OK to clear out (just use a smaller washer reservoir, potentially elsewhere), but the DS no beuno
    • Well, all the best with the new camry It was interesting to hear about the UK process, it is generally a lot more streamlined here with a shipping agent looking after all the import side (noting the exact final price can still be a surprise.....) and I've used a few different brokers on the japan (or US) side, and never had any trouble with any of them....luck of the draw I guess. You mentioned you didn't get the auction sheet (understandable since you bought it from a dealer, not auction), but I always try and get hold of that because they are pretty thorough. I've imported 2x R grade vehicles over the years and both were fine, repairs in Japan are pretty thorough compared to here in Oz.
