The Build 73 240Z

[JDM-TOY]

So progress has been quite slow getting this setup complete. 

Sometimes information given by people is not the full story so you need to dig deep amd look for more information yourself. 

Had some clearance issues with the rear disc as it was not spinning freely due to it touching the caliper brackets. So machined the discs today shaving off 3 mils and now the disc is spinning freely.

Front end is in exceps calipers. Rear end, the diff is in and control arms with new bushings. Hopefully Friday will put tye rear shocks up and get the car off the rotisserie.

The car is so dusty man I was sneezing like I had hay hay fever lol

[JDM-TOY]

Finally managed to get the 240Z off the rotisserie. 

We have a issue were the front discs are a little too big and the SW front bracket is short for the R33 calipers so the two dont meet. The rear calipers fit good and there is good clearance for the wheel to spin freely. Will need to sort out possible smaller discs for the front. Anyone had this issue before?

Are you sure they are R33 GTR calipers and not R33 GTS-T? Different diameter discs so calipers will be different.

[HKSZ]

Stewart told me he uses GTS-T r33

Looking at your photos  the whole struts may need to be swapped left to right to clear steering arms?

@KatoKid Well we got the calipers from SSS Automotive as SW recommended SSS and he said get the R33 GTR, then we found out Tim is SW son. I will call Tim and speak with him on Monday and see what he says. I may of misunderstood Stewart. Stewart is in Alice Springs ATM not sure when he gets back.

@HKSZ Do the calipers sit on the front or the back, like the position of the calipers? Because they did look odd when I positioned the caliper on.

 

But anyways worse case scenario I can sell these calipers as they are basically new and rebuilt the GTS T ones.

My set up uses GTS-T calipers but its different to SW so check my signature for the link.

Either way you will need to swap struts from side to side as the calipers have a leading and trailing design with different piston loaction: refer the link below:

I have the SW setup with DBA rotors and R33 calipers and everything bolted up fine, I can't say if the calipers are GTS-T or not. Naybe you can tell from the pics?

@KatoKid Thanks Dave, I will sort the struts out on Monday. My rear calipers are like Aaron's not sure what the front ones are on his. Will need to go through his build thread.

Thanks @ZED660. My front calipers are definitely different from your ones but rear are the same. Ill take a picture tomorrow of the fronts I have and post it up. 

 

Thanks guys, this is why I love this fourm. Great help

Hey Guys 

So a little stuff up on my end were I purchased R32 calipers rather than R33. Basically all I need to do is change the disc to the small 280mm ones for the R32 calipers and it should all bolt up. Small mistake causes headaches, should have paid attention...

[gav240z]

Sounds like what we refer to in computing as an ID-10-T error or PEBCAK.

Glad you got it sorted.

 

Would be easier to buy R33 calipers than swap discs?

Hey Dave yeah it would be but I have already spent so much on the 32 calipers with powdef coating, new seal kit.

[JDM-TOY]

Hey @ZED660 what size discs do you have in that picture you put up?

Hi,

Approx 295mm, they are DBA 5040IS.

[JDM-TOY]

@ZED660 Thanks Geoff. 

I went out and got a pair of R33 GTS-T calipers today from Skyline spairs. Will do a test fit on Monday and see how I go. If it fits well I might just do what Dave @KatoKid said and just replace the calipers rather than changing discs. 

Cheers Guys

[260DET]

Personally I'd go for the bigger rotors, 280mm dia is small by today's standards.

[ZED660]

I checked the DBA site the rotors are 296mm, with decent pads (Hawk) I find the brakes more than enough for the track.  But then I don't have a V8 auto!

@ZED660 Are you running standard master cylinder and booster? I had a few people tell me to replace the master cylinder with one that has a 1 inch boar, not sure if that is overkill on a mild cam L28 

[ZED660]

Yes, I have a Willwood 1" master cylinder with standard 260Z booster.  I previously ran the standard master cylinder with the Toyota Hilux brakes and had no problems and good pedal, however when I fitted the SW kit I figured I would change the master cylinder at the same time. You might want to fit the brakes first and see what you think of the pedal. My Willwood came from Rocket Industries at Huntingwood. If you do change to one you have to make a small adjustment to the push rod length in the booster.  The attached link gives instructions on what is required.

[KatoKid]

You will definitely need to got to a bigger master cylinder, just for fluid displacement.

The standard 15/16th R33 master/booster works very well with good assistance, feel and travel.

Hey guys 

I managed to rip out all the wiring behind the dash and take it to Justin from Prowire and I wanted to email him a wiring diagram that is the Aus or close to as pissible for him to reference. 

Just been searching the net and I came across this U.S website that has a few for early and later model Z's diagrams.

http://nicoclub.com/archives/datsun-240z-260z-280z-280zx-wiring-diagrams.html

I just wanted to know if the 73 diagram is accurate as I noticed its the U.S 73 has the rear marker lights and there might be a few other things that the U.S Z had that was not on the Aus Z that I dont know about.

Also I took all the guages to AttSpeed Instruments to get checked and cleaned up due to the sandblasting dust and I noticed that the bulbs were not attacheind to the back of all the guages. I did notice only two on the wiring harness but all the others were missing. Is there anywhere I can purchase the bulb fittings to get Justin to wire them in? 

Happy wiring
