300zx Made in Japan

Updates?

Its been a long haul the last couple of days sorting all the little pain in the butt items that seem to take so long to do.
So yesterday I filled the motor with oil and diconnected the cas and cranked the motor a few times to get some oil circulated.
Was going to see if the old chip in the ecu (for stock motor and 370cc injectors) would let the motor idle at least with the 700cc injectors fitted as I had not fitted the Nistune yet. So I used my precision fuel pressure reducing tool (my trusty vice grip) to crimp the rubber fuel hose a bit and after the third crank the motor sprang into live. Naturally it was running a bit on the rich side but the motor was mechanically quiet, good oil pressure, no oil smoke, no oil or water leaks, so far all OK.
Also did a checked that oil was draining to the sump from the turbos as I had to mod the OEM banjo bolt built in oil restrictor as the GT2860rs turbos I got have oil restrictors in the oil line fitting at the turbo. For those intrested the OEM banjo bolt with the letter "K" on it has this restrictor which is difficult to see which I drilled out to 4mm for my application.
I am very relieved at this point and today the ecu comes out and will fit the Nistune and try to change the "K" value for the bigger injectors and try to learn how the tune this thing.
Next phase is to service the front calipers with the new seals, paint the calipers and fit the braided lines and EBC yellow stuff pads.

Hey Charl, was wondering what your thoughts are on this...I know you run dual wide band afr guages and my question is do you think it is an over kill?
My feeling is it is not as you are able to monitor both banks but many disagree and say its a waste.
This also goes to anyone else as well....thanks

Two looks better then one. :facepalm:
I think that the only advantage we have with the "V"g30 is that we have dual exhausts, and there for we can monitor the two banks individually. Although you can't adjust the afr on the two bank separately, if an injector would k@k you'll at least have it narrowed down to a possible three. But for tuning purposes one is more then adequate.

I've got two because I'm doing narrowband simulation.

Anyway some small up date....I ordered and innovate wide band afr kit last year and by accident the vender sent me 2 , after complaining to them about the fact that I only wanted one and had already paid customs duty for the extra one I would now require compensation for the return postage costs back to them.... they decided I can have it for free....so nice of them.
So now I have trial fitted the second gauge to the dash and now must wire them both up.

Guys, how critical is the orientation of the o2 sensor fittment on the pipe wrt it being fitted between 10 and 2 o`clock?
My down pipes from Z1 has 2 o2 sensor bungs and the top ones are used for the OEN narrow band sensors and the other 2 I want to use for the wide band but its orientation is around 6 o`clock.

Removed the Turbonoz chip I had for the previous stock (1 bar boost) motor.

And fitted the Nistune daughter board.

I also managed to complete the big brake conversion and fitted the EBC yellow stuff pads and 350z EBC discs to the to the front as well as the braided brake lines front and rear.

She's getting there.

Hi Charl, its getting there slowly, was looking at my z1 down pipes as they have a spare blanked off o2 bung I was hoping to use but after research and comments it seems it is not the ideal place, not sure what the manufacturer intended to go there. Will have to get my bungs fitted before I do any sort of tune.
How did you run the cables from your o2 sensors to the guages? I was thinking from the left and right hand side wheel arches where the other looms go. Any secretes/tips to this ball ache job?

Some idiot drilled a 30mm hole thru my firewall behind the batery so I went thru there with my cables but I think left fender and in with the door harness would be the best. I believe the additional bungs would be for egt probes. I should have two stainless bungs left so left me know.

Tony, what's the switch for next to your time display?

wanne gaan julle 2kies biekie dice???

Hi Charl...thats my 200kw nitros button....
Ha ha ha..I think its the button for the aerial that comes up on the front bumper to guide you for parking which I dont have anymore. It is a JDM option.

ek het jou al teveel kas toe gery

O k, I see. Would have been nice if it was a bit of nos, just to counter lag. 😉 😉

Are you going to be ready for next Sunday?

Hi...yes it should be able to get there on Sunday on its own steam although its not very photogenic at the moment with its current body work condition, it is driveable at the moment but I am getting the o2 sensor bungs fitted today so that I can do some tuning using the AFR gauges. I am also going to get a centre silencer fitted and my jap style back boxes fitted.
Then the last and final phase will be a complete respray. 😀

Great.
