I am extremely happy, it drives like a standard GTR @ 60kmh in 5th gear (1300rpm)

2nd gear breaks traction at all 4’s on shear acceleration J

Please refer to attached graph, this is my 4 wheel dyno tune figure by CRD on the 20th June (my birthday)…

THE CAM GEAR DEBACLE…now proven!

I was there from start to finish & saw the comparable difference.

The red line (on the graph) is tuned with cam gears at 0 degrees

The blue line (on the graph) is with tuned cam gears - keep in mind I do have the poncams…what a difference!

Jim has made an additional 100Nm without sacrificing top end delivery…

This proves that adjustable cam gears do make the difference & that Jims dyno tune has made a massive difference in torque!

Only the experienced guru’s of the industry are aware of this advantage.

I also had a long discussion about road tuning with Jim – he is of the opinion that you cannot simulate ‘load tuning’

i.e. load tuning at various rpm’s for a specified time period, where can you do this on the road & how can you road tune a car under load?

At the end of the day Jim has 15 years experience with GTR tuning & the experience alone is working with all facets such as drag, targa, circuit, national teams, race production class etc….who else in Australia works alongside with top tuners in Japan & national racing teams? I guess this is why he is the busiest workshop in Australia, just have a look at the number of performance cars he has in his workshop & yard (over 30 cars).

YOU PAY FOR WHAT YOU GET – yes other tuners are cheaper but you will not reach the maximum potential if cam gears are not adjusted to suit the setup.

The way I see it, if you are prepared to spend over 10k on an engine then investing another $400 additional for a proper tune is the way to go…

Question: would you pay the small difference in tuning for an extra 100Nm of torque?

I am not here to convince you or sell CRD but I did want to share my experience with you as I am extremely happy with the outcome.

Thank you Jim ;)

Regards,

Marko

yeah, I was curious about that too. my guess is boost controll. certainly a very nice number. Very sharp curve. BIG fat top end, but the bottom end seems a little dissapointing to me. I would personally like more 'area under the cruve', but i don't think that's a reflection on CRD more a turbo choice thing. Do you have a graph with Y axis in RPM instead of speed? if so could you post it up?

enjoy mate ;)

Agreed, but you'd be a miracle worker to get Jim to tune a GTR for $400.

$500 is what he normally charges just to dial-in cam gears, let alone TUNE the GTR.

A basic GTR tune starts at $800 and rapidly increases from there.

I have never stepped foot in that workshop without being slapped with a bill LESS than $1000.

I spoke to them today they said $350-750 for a full tune :) who knows but..

Doing a power run on Saterday morning to see what this biatch is making :Pimp2:

Merli,

Im with blk180....he is saying that it is only an additional $400 or so in comparison to most tuners who charge anywhere b/w 500-700 etc...

Im in agreeance with you marko....fantatsic results...wow pretty impressive!!! Im amazed at the difference with the cam adjustment...thats worth the extra $$ to me!!

I'll bet you $50 that he wants to change the oil, and spark plugs before tuning it.

And it seems the more power a GTR makes, the more he charges... Presumably because there's more liability and less room for error with highly-strung GTR engines.

Understandable I guess, but it gets old when you're told "$350-750" and then get slapped in the face with a $1500 bill.

Anyway, good luck, and you have to come to the next dinner and let me take it for a spin... I'm having major power withdrawls :P

P.S. Have you put on an oil cooler yet? :squint:

      Mistakes were made, my R34 Story

      (it is a brand new ported mellings pump) I suspect the lack of pressure is due to the leak. It was *not* that low in other logs of oil pressure in the past. It wasn't that hot either, but not far off.

      Would a Mellings oil pump be a viable option  From my time with a LS, and talking to tuners and LS specialists, the "weak" OEM oil pump is one of the first things they recommend to swap out if I was going to give the engine any high RPM I opted for a Mellings high volume, with the high pressure springs and I never had a issue with it Cost wise they are not expensive in the scheme of things

      My new to me M35 Stagea wagon

      By davemoto63 · Posted

      Just bought a 2002 Stagea 250tRS VR-X Four AERO VQ25DET and spent the last two weekends cleaning and detailing it.. still have to do the wheels and the engine bay but the rest of it came up nice. Imported 2011 to S.A. and I'm the third owner since it was imported. I met the guy who brought it over, he went to Japan and picked out the car, bought it and ordered the wheels. He also gave me a list of stuff he did to the car with receipts. Coil overs (I have the original springs), 3" exhaust from the dump pipe back no cat, Custom dump pipe,(I have the original exhaust), Plenum spacer, 18" custom Work XSA wheels (need restoring, I've made a start..), Shift kit put through the 5 speed tiptronic auto, TV and menus/screens changed to english, Australian DTV tuner installed in rear. I've just had four new discs and new pads as well as all the fluids including the brake fluid replaced. I have all the receipts for the last 15 years and the import papers in a nice folder. Car looks great, goes like hell but fuel economy is not a thing lol.. pics next..

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

      By silviaz · Posted

      I ended up in this rut again lol, and used a shit ton of filler. One thing I can't understand is, even after using a big long block and going in long X pattern strokes, I always end up at bare metal again with no filler, and my repair started at one end of the door and now I've chased my tail to almost the other end of the door. I was thinking of hitting the panel with a hammer where it might be a high spot and making everything low then filling it, I did this on a small section on my other door by mistake and I think I fixed it lol. Is this a bad idea? The other thing is with guidecoat, whether it's the powder or spray, after I sand all the guide coat off, it doesn't reveal anything for me in terms of high spots and low spots and makes it especially hard when it's bare metal (at least in powdered form), am I doing something wrong here, or likely a high spot I keep going over and creating valleys? Lastly, stupid question but, is it possible that after sanding if I only sand over the filler area where I know to be a dent that it's impossible for me to dig into that dent? Unless there are other problems which I missed.
