Awesome update mate, sounds like you’ll have a little time up your sleeve to to get those shocks in. The 5 lug conversion will be interesting to follow too 👍🏼

Hi guys! I just recognized that I haven't posted my film of my Piazza doing the "Night Run" here. You might have seen it in some of the Facebook groups though as I've tried posting it everywhere! ;)

Latest news for the Piazza is that it's started to drive like crap. Significant loss of power, and the engine sounds like a lawnmower, and misfiring or something like that. So that's just great news just as I am gonna put it away for winter. I don't even know where to start looking for the problem...

Sounds like an electrical problem. Check your spark plugs for any ceramic insulation cracks, have an electrician check your leads, and distributor, etc. Some of this stuff can be visually inspected, eg check the leads are properly connected to the plugs but if you’re still scratching your head then go to an auto electrician.

As I can’t hear this sound in person, could it possibly be the exhaust manifold has separated slightly from the head which needs tightening (provided the stud/s hasn’t broken off). Remove the heat shield to have a better look and listen to where the sound is coming from.

As a precaution also check the condition of the engine oil in case you have a cracked head and getting water mixing with your oil. It probably isn’t that because you would have mentioned the engine is also overheating.

Well winter is slowly passing by and I've been making plans all season long! :supz:
During these dark and cold days I have been stocking up on parts and modifications that will begin to take place sooner rather than later...
Some stuff I've been loading up: GReddy boost gauge, GReddy oil pressure gauge, GReddy Profec B Boost controller, TRUST 4-point seatbelt, TRUST GREX shift knob, Spax adjustable front shocks, Nissan Z31 wheel hubs and looking after more Skyline R32 brake components to finish the 5 lug conversion. Gonna be an exciting year for the Piazza hopefully!

"I don't post often, but when I do it's about damn time!" ;)

So Japdays 2022 at Mantorp Park, Scandinavias biggest event for japanese cars is over for this year and as usual you found me and the Piazza there!
I also got to meet Jan from Norway who actually took his Piazza XL from Norway and came over! :cheers:

Image

Image

Now let's see what's been done so far to the Piazza this season!

To begin with I had to get the car through inspection again, and I tried the easy way and went to a station with my stainless exhaust mounted as it was.
Unfortunatley they didn't like the missing cat and the sound of the exhaust... :finga: The headlights were also foggy and not sharp according to them.
So the same friend that built the exhaust first hand helped out and fixed the cat - CHECK! Then I screwed a dB killer at the end, screwed down the headlights to the max and went back. It was a close call, but the inspection guy let me through with some wise words and passed the car! :heart:

Image

The Piazza then got a proper big service with new belts and pulleys. Also managed to enhance the black paint on the valve hood.
Changed the ignition cables, distributor cap, spark plugs and fuel filter as well to see if the engine would run smoother, but it didn't.

Image

Image

Image

Finally got the new adjustable Spax shock absorbers installed in the front! Back installation is still on the to-do list though.
Image

Then I got to the wiper arms, resprayed them and converted them to hook mounts to be able to buy them anywhere.

Image

Installed Veilside shift knob, Bomex horns and a Raid steering wheel that I found in the boxes in my storage! :bounce:

Image

Then just before Japdays I finally found and changed the weatherstrip for the sunroof! Wohoo!

Image

Image

Also got featured in one of Swedens biggest motor magazines! :cheers:


Image

Image

After a proper cleaning and waxing I love this car more than ever! :heart:
