Turbos are on. Just trying to find a way how to route the power cable to the starter motor... my driver side turbo is in the way!https://uploads.tapatalk-cdn.com/201...f0b09e82cc.jpg

Warning!!

I almost lost my Z tonight due to a fire. With the aam kit, you have to remove the plastic harness around the starter motor cable, for the cable to be more flexible and move around the compressor housing.

When fitting the transmission and fiddling the starter motor into position tonight, the rubber protection sleeve around the starter motor cable rubbed against the turbo compressor housing, causing a shortcut in the system. All of a sudden I noticed smoke from the engine bay, and luckily we could act fast and disconnect the ground cable on the battery. If we kept working underneath the car.. it might had been too late to save the car.

So, advice is to very well check your clearance and add extra protection..

Agreed! That sounds very scary!

That would have been heart breaking. :eek:

Martijn_b 03-01-2019 05:57 AM

Yeah.. im a very detail orientated person when it comes to working on the car. I just also forgot to remove the battery again after i put it on to flash the ecu. And when you mount the transmission, everything wiggles and tilts a bit, which caused the clearance issue.

My plan is to check the fuse boxes tonight. The cable is insulated again already.

Anything else to check before plugging the battery back on?

Your shorts right before you make contact with the battery and terminal. :icon17:

Alright, i didnt get to start the car. Spent most of the time i had today on making sure my electronics are OK. Spent another hour on understanding how to connect the CJM fuel system. I wish CJ just put a drawing in the manual, much clearer than the pictures. Especially if english is not your first or second language. But i think its connected correctly now (see attachment)


Put the battery back in, and no weird signs so far. But starting the car will be the real test.

Because i still have 55 quarts of g12 plus longlife pink coolant, thats what i put in. Its silicate free, which i think is important.

Which CJM return did you get?

Martijn_b 03-14-2019 07:45 PM

Hi,

I got the CJM S1E? I think.. its the fuel return kit without the fuel rails.

Car is running now. Currently in the process of tuning, and solving all the little gremlins along the way hehe.

Good to hear. :tup:

My build is finished!

Finally, after a lot of months the build is finished. I posted here on the forum about a few issues that i encountered during the process. Mainly concerned around knock. We found that the ECU sometimes "thinks" that it hears knock after flashing it with EcuTek. When you remove the 2 connectors to the ECU (in the passenger side footwell) and reconnect them after a minute - it's gone.

Another issue was the water hose on the driver side. This new hose on the AAM kit runs just 1-2 inches above the exhaust manifold. It worked well for a few months but then started leaking. I replaced it, rerouted it and protected it with firesleeve.

Then at 11 psi, my clutch let go. This was my fault, I had the Z Speed easy street clutch, which is fine up to ~400wtq but can't do anything above that. I replaced the disc with a ACT heavy duty 6 puck and this is holding up great.

So, the current status is that I am running 4 boost maps, being: 6 psi / 8-9 psi / 10-11 psi / 12-13 psi. I didn't prioritize putting it on the dyno yet, but I guess that i am well above 500whp. I did a 60-130mph pass in just under 7 seconds at 6.93. For reference; a Q60 with tune and bolt ons does 9 seconds, a stock GTR around 7.8s, a Dodge Charger hellcat around 7.6 seconds and a 911 turbo s around 7.2 seconds.

For now, I'm enjoying the car as is on 93 octane and will probably just do minor upgrades here and there to perfect it. Drove it again on the Nürburgring and had a blast, 187mph on the autobahn on the way back was fun too.

I have some video's and photo's on Instagram: @Boosted_Fairlady - feel free to follow me there as well!
I will post the dyno results as soon as I can be arsed to go there ;-)

Oh, and special shout out to:

- Seb @ SpecialtyZ. So much patience, amazing customer service, never got annoyed by my questions. We went through many iterations to get the car where it is today. Thank you!

- Joe @ Z Speed: Very responsive, good advice, knows his stuff and fast and reliable shipping.

Great job and enjoyed following you and talking to you on Instagram. I am going to hold you to your word about meeting you at the Ring some day. It has to be amazing in as you blow by those six figure German persuasion sports cars.

Made some good business decisions lately, which opened up the chance the have a look at the 370's big brother: Godzilla.

Drove the R35 yesterday, a facelift DBA model with tune and exhaust. I liked the sound and the easy power delivery and enjoyed the drive. Unfortunately it didnt bring what I expected, although it's a very capable car, it's really more of a GT than I thought it would be. In the Z I really have to work and pay attention to put down the power. The automatic gearbox of the GTR together with the 4wd system makes it so much easier to drive it fast - that it's almost too easy.

Conclusion: it was nice trying out the GTR, but I decided to stick to the 370 - it matches what I look for in a weekend car much better.https://uploads.tapatalk-cdn.com/201...a04138ea4a.jpghttps://uploads.tapatalk-cdn.com/201...f9a9034ee0.jpg
