Project 'Wheezy' Coupe

[Dale FZ1]

@Wheezy depending on who manufactured your turbo, there may well have been impeller options. With Kinugawa there certainly was. From recall, I selected the "middle spec" turbine which was 11 blade (stock being 12, and 9 being the highest flowing + lightest), and "standard" 6+6 compressor.  There was also a full 12 blade billet comp impeller option for high boost applications.  Thrust bearing was about 270 degrees for all units.

With all of that, I ran the 11 blade turbine, 12cm housing, standard 12 blade comp, and the compact comp cover.  Main target was decent turbine flow efficiency, and a modest power requirement under 400rwhp.  It performed the required task, reliably.  And there was room for much more.  Boost response was satisfactory, not "awesome".  At the price point there was little to complain about.

I reckon yours will be a good thing, interested to see whether it can run to your power target.

What I really like is your choice of Emtron and some decent sensors.  Suggest you ditch that OEM CAS.  I found greatly reduced timing scatter with a NZ Wiring sensor kit, if that's any help.

Mines a genuine Trust turbo. So whatever they did back in the day.

RE: CAS, will probably go the High Octane kit.
Probably not happening before tune, perhaps that way I can keep the power down for now and get used to driving it I guess

[Wheezy]

Came so close to starting today.
Has fuel, but no spark.
Spun the CAS by hand, but no spark.

Coila have 12v on the multimeter.
Ran an ignition test on the ECU and the coils fire.

Noticed the battery voltage goes to 11.7v when I crank.
So, charging the battery up to be safe, but it's brand new.

Looking at ECU settings to see if there's something going on to disable the spark.

Spent the day flushing out the old fuel and putting some new E85 in it along with some fuel doctor.

Based on my digging through the logs and talking to my tuner, it looks like the emtron is designed to suit the Neo CAS.

Will double check with Emtron, but probably I just need to do a pin swap for the signal wire and trigger wire and she should be good to go.

[Wheezy]

Swapped the CAS pins.

Great success ?

Engine bay back together more or less.

Apparently the Pyrex Gas Lens for my Tig is turning up this week so I can finish making my new intake pipe.

 

Then it just needs the panels put back on, clutch and brakes bled and a new fuel pump for insurance and it's ready for the dyno.

[Wheezy]

Clutch bled and the rear wheels move which is a relief.

Just need to bleed the brakes, change the fuel pump to a fresh one and put the panels back on.

Tune on the 17th of this month

[Wheezy]

You know it's tune week when...

Viscous clutch decided it didn't want to live anymore.

Ordered a new one from Nissan.

Cost of that hurt the bot bot a little.

 

Then went to bleed the brakes and found $80 of rbf650 on my floor. Fuuuuuuuuuu.

 

Got the brake line junction out.
Messed that up badly... My own fault.

 

To distract myself I did a final tidy up on the GTR loom I replaced my 20 loom with.
Less crusty now.

 

Will go get some essentials for my pets tomorrow and grab a new fitting from Hopper stoppers

[Wheezy]

Brake line junction being picked up tomorrow..
And viscous clutch is due too.

Went to change the fuel pump and decided to clean up the wiring at the bulkhead as I've not touched it since owning the car.

Looks like it's had a bit of a hard life...
It will only be temporary until I get dual pumps next year with an aftermarket hanger etc.

Had a good laugh at the f**ked up wiring job too...
Explains why we had mystery wires when doing the silvertop 20 conversion 14 years ago.

[Wheezy]

Viscous clutch on and brake lines fixed.

Thoughts on the new intake pipe direction?

[niZmO_Man]

delicious hot air?

[Wheezy]

Pro tip.
Bosch BR540 fuel pumps don't have internal check valves.

#f**ktuneweek

[Wheezy]

Tig skills getting better.
Might clean up the welds tomorrow with some polish.

Went back to a standard cup instead of the fancy gas lens, not skilled enough for them yet.

Looks awesome good job ?

[PranK]

Yeah looks fantastic!

[Wheezy]

Car is finally back together ?

[PranK]

That looks amazing!

Thanks man, much appreciated. It's 90% the way there to what I imagined it would be.

I've never gone all out like this before on a car.

So much planning involved however. Other than the long motor build, I can't imagine how much it would cost to pay someone to have do it all for me.

 

A few things I need to tidy up and others is do different. Hopefully there isn't a next time for this cars engine bay.

 

For something completely different, I have a VN Berlina to build (thinking LS6) and a Honda SL70 mini bike to restore.

Nothing like keeping yourself busy!  

Mini bike restore sounds like a lot of fun!

Lots of work, was my family's farm bike for years.

Saw a mint one in Tokyo last year and got inspired. Hope to restore it with my kid as a project for him so he can learn to ride
