Datsun 280ZX IMSA GTU race car build...
Re: Datsun 280ZX IMSA GTU replica race car build...
Cam Synch sensor is fun. Just a pain to mount and weld. Sensor is a think a Honeywell GT 101 i think. Ill check.
Adjustable blade style trigger mounted to cam sprocket. I'm not sure if this is ideal but i cant think of any other way. The obvious down side to this arrangement is that if you change the cam timing you have to adjust the cam trigger offset in the ECU. Not a biggie but just one more thing. That of course is if you want to run accurate cam sensing.
Photos will be on there way tonight.

A few small jobs done.
I pulled the pedal box out again to centre the balance bar.
I did notice my front master cyclinder is 1", and rear 7/8". These were sized for the original 6pot/4pot wilwood calipers.
I think the 1" may be a bit big for the AP Racing 6pot... will send an email to Wilwood and Race brakes and see what they both say...
Had to trim one of the modified rear trailing arm mounts (both sides) to give better chassis clearance.
Gave it a squirt of paint, and now all bolted in for good!
I added some extra rubber/Nitrile to the rear mounts top and bottom so less play... one day will see how it goes...

Picked up the rear shock lower bushes, and the diff mount & machined washers today.
Shock bushes fitted perfectly.
Rear mount is getting re-made as they machined the main hole 4.5mm incorrectly...
Not my cost, but besides that they made a fantastic job.
Bushes & washers.
Bushes Fitted.
The brakes hats are currently being machined by Znoelli...
I got a new front 3/4" Wilwwod master cylinder to replace the 1" one i have as it seemed a bit large, and Racebrakes agreed...
And another key item was a replacement steering column from a very helpful Z Club member, as mine had a damaged spline. Not sure where that got damaged, as it had the steering wheel fitted many moons ago...
Will post pics this weekend.

Picked up new diff mount today.
Machined from a block of Aluminium by Stainless Machining in Penrose.
Very good and fast service.
I was going to get it anodised but to eager to get it fitted.
Was happy the way it all went together finally...
And up close...
I have since loosened off the bottom nut a couple of turns as i probably over tightened it based on crush of Nolathane bush.

Got some rubber sections from Para Rubber to seal around the fuel cell... came out good.
Also got a red spray bomb to touch up the Steel Box and it was a perfect colour match... surprised.
Made a couple of 50x3mm Aluminium restraining straps, will look at options now to seal up the dry break valve, may try the plastic weld as mentioned some posts ago....

I was going to have a crush tube in it, but decided to use some bushes i had on the shelf that fitted, but no crush tube.
Will keep an eye out for possible replacements, as the size i used apparently is very common.
They were some 4x4 Nolathane bushes...

Hi mate just out of interest what is the an fitting welded onto the diff mount do?
If you look at the picture in the post on 29th Nov 2018, you can see the two top holes were welded up, as not much room with this diff cover on the 280zx.
The AN fitted to the side is for oil return if a diff cooler/pump is used or a breather...

Ok, been a bit quiet...
Brake top hats due this week!
Hatch test fitted but ended chipping the roof. I could not quite hold everything when aligining it on my own.
Nothing a small blob of blue paint wont fix.
Started cleaning the gearbox. Its new, but got weathered... a few more hours elbow grease once my fingers have recovered will see it ready.
Its a NISMO S15 close ratio 6spd, had a bit welded to the bell housing to mate to the L28.
nearly there...

I saw on FB some vapour blasting and would like to do the same.
The results looked impressive.
I was just a little worried about water going somewhere i dont want it to go... and i dont know who does it...

I too have seen it on Facebook and I was thinking I'm going to need to pull the housings off to avoid causing any issues, Wag's gearbox and performance shop here in Wellington look like they get it done so i can ask them when i pick my gearbox but I guess it will be someone local that does it for them.
