Should be fun, I'm colour blind.

Hi Andy, Love your work.
I got mine going with the custom fabricated thermostat housing, but I wish I'd gone with the Electric water pump. Good idea, Your an Ideas man!
Regarding track footage, I did have one on post No 241 I think it was."Track test day at Hidden Valley" I'll try to do more, but it's Monsoon weather here at the moment. Hang in there.
Udo.

Progress.......
I've unpacked all the electrical and MS3PRO kit to get my head around that pile. Looking forward togetting that installed.
There seems to be a light at the end of the tunnel. Keeping at it.

Looking awesome Andy.

Back in 2011 when I was doing the Link ECU install I got the O2 sensor locations wrong by putting them on the downstream side of leaky collector joins that were impossible to fully seal up, and had to move them and muck up my new header coatings - I recall you have V-bands but make sure they are 100% leak free if you are going to put O2s after those. Have fun with that birds nest - not far to go before you can make some noise!

Cheers, Andrew

Looks good Andy, like everyone here I can't wait to see some footage of it making noise. we are looking at Dash setups for our 300ZX and there are a few options out there and a wide price range as well. We have put the radiator in the boot and also looking at the electric water pump options most likely go with a DaviesCraig. Keep up the work rate, always love your progress reports.

Cheers Leon.

Udo, Andrew, Leon thanks for you words of encouragement. The O2 sensor is before the V band joint which has a very good seal so hopefully no issues there.
Pulled the old(new) water pump and trial fitted the Electric setup. There's a little more to it than I hoped. Just ordered another dozen bits and pieces.. now waiting on 2 US parcels. Phew no extra tax

While I wait for parts I've made a start on the wiring. As a whole it looks a bit daunting but once you break it down in it's separate components it's OK.( I have been reading the 300 page MS3PRo manual for some years now.
I've just mounted most of the Electical components and will start to wire up the starter and charging circuits then onto the engine management, fuel, ignition, fans then displays and controls etc.
Been looking at a starter battery. Lead Acid and AGM weigh a ton, 20-25kgs. So I looked at Li-on starter batteries, there aren't that many near the South pole in NZ and cost a bomb. One came up on the radar. A powersports PLFP-30L Motorcycle battery that is rated at 440cca but tests at 730cca and Weighs 1.6kgs. 700cca meant to be ok for a 7ltr motor. These have been used already in powerboating and other track cars and seem to do the business. The Battery man said be prepared to be amazed. I am already.
So it came home with me. I'll set up a jumper system to help things out.

Andy,

I’ve been looking at theses LiFePO batteries as well and they sound pretty good. I was particularly looking at them due to their smaller size and weight for different mounting locations. I ended up settling on the front mounted battery location mainly for weight distribution and to keep it out of the cockpit just forward of the footwell bulkhead. I’m holding off on final purchase of the battery (traditional & AGM seem to not last like they use to) until I really need it but cost and availability will drive final purchase. With your battery choice, does it have the reserve/self jumping feature that allows it to activate a button to give a boost to the primary starting cells?

 

[Andy R]

Hi Devin, no reserve button. They don't have a long cranking cycle time(obviously due to there small size) hence it will have jumper battery assistance in the pits. Also orientation is not an issue. Battery man said keep it topped up by the battery charger.
