Light weight, Japan-style 240Z

Whether you need adj. bias in your car will depend on your setup.

My setup with Hilux fronts and drum rear was fine, but as soon as I fitted the R31 rears, they would lock first.

I ditched the factory prop valve (but retained the differential-pressure warning switch), and fitted a Willwood prop instead.

It was dialled in on the brake testing machine at the inspection station and was a much better car to drive.

Now I've fitted vented fronts, I expect that we may need to dial in a little more rear, but time will tell.

Only testing will tell if you need to make adjustments.

You have a 240z right - so did you remove the line pressure think from the back T-bar from under the car? I know a mates 1970/71 (under chassis 1000) had a little cap and spring in there to keep 10lb of line pressure which is required for the drums. On his car he just removed these from the T-Bar/splitter and all was good.

Mine only had a plain 'Tee' there - no integrated residual-pressure valve.
(which had me stumped when I first worked on the brakes, because I was expecting one!)

Couple of pics with the wheels back on...

Had a problem with my L28 distributor getting all loose and dodgy, so I'm fitting a Kameari item which runs a proper internal crank angle sensor and twin ball-bearings, plus a lot bigger cap with better quality bits. I'm also getting that re-tune I've been planning on since day one, to coax a bit more anger out of the L32.

Where did you get your efi set up from Ben?
cheers

[BenZed]

It's an OER kit, which I can supply new for $2300, see this thread:

The kit on my car I actually bought second-hand on Yahoo Japan, but you don't see them often

[BenZed]

Just had the Kameari distributor fitted, along with an LS1 ignition coil. Now I've discovered an issue with the alternator dropping voltage, so I can't tune it properly yet.

That distributor looks identical to a L28 Turbo distributor..  What's inside? just a CAS sensor?

Are you talking about the Crank Angle Sensor sensor? 

[Zedman240]

Yep. Could have written "CA sensor" or just finish the sentence with "CAS".

[BenZed]

Yes the cap is hitachi, casting is by Kameari and as I said before, twin bearings, different drive gear and yes chopper wheel/CAS inside.

Ben, Are these an easy fitment, what is the going rate?

[RB30X]

Grab some zoomed out pics next time your there Beno.
cheers

They come as a kit with an Ultra ignition box, 62,750 yen in Japan.
I didn't use the Ultra ignition box but set up my ECU to use the CAS in the distributor. Easy really as it just has 12V power and a signal wire. Can't use the factory tacho unfortunately.
