I rounded the nut on the master for the old R32 brake line - it was completely seized - so i decided to custom 2 lines from Master to the ABS unit.

Front Master Port - $75.00
 
Left Fitting - Fixed Male 
Left Fitting Size - 3/8 x 24 UNF (-3 AN JIC) 
Left Fitting Angle - Straight 
Right Fitting - Swivel Male 
Right Fitting Size - 3/8 x 24 UNF (-3 AN JIC) 
Right Fitting Angle - 70° 
Length - 97cm - extra 1cm

Rear Master port - $75.00

Left Fitting - Fixed Male 
Left Fitting Size - 3/8 x 24 UNF (-3 AN JIC) 
Left Fitting Angle - Straight 
Right Fitting - Swivel Male 
Right Fitting Size - 3/8 x 24 UNF (-3 AN JIC) 
Right Fitting Angle - 70° 
Length - 91cm - extra 1cm

This is how the line will roughly look like:

This is roughly how it looks out of the car ^ i have made a few adjustments to the Angle of the BMC Fitting - as well as threw the adapter away cos it was the wrong size - and remade the whole line again. But it looks very similar - the most updated line specs is above

This is how i plan to run it - please use imagination a bit - i will take more pictures once its installed. But the 2 lines will run across the firewall similar to the original hard lines.

Confirmed the Plug is the same as BM57 - its quite hard to get the plug - it is shared with a LOT of different cars - R35, Pathfinder, G35, Subaru WRX, Ford Fiesta - but its almost impossible to buy one - and 100% impossible to get in Au

I found the details in the thread below - have to thanks to @BK for ALL the research he did - especially in where to purchase. MOTORCRAFT WPT-1385 is the part number - meant for Ford. Wired up - it will fit perfect.

Below is the Final completion - remove the 4 nuts in the car cabin at the brake - and remove the R32 BMC and Booster

R32 Right booster

R32 and R35 U Clevis and - the one at the bottom is from the R32 GTR - MUST reuse this for R35 Booster

There is a Spacer for the R35 that looks like this - this will not need to be used - it should be mounted directly on the FireWall

Just use the Gasket and put the Booster on the Firewall

Roughly how it looks when mounted up

This is the complete work - with 2 sets of Custom HEL lines.

Once installed - i found the following - the brake pedal is slightly lower than the R32 Original

Overall it was very easy to do - and a massive learning process for me. Had a lot of help along the way from @BK and @Meap that did all these first. I hope whoever that attempts this moving forward - this Post will help you. The biggest problem i faced when doing this was the BMC Fitting size and how to run the lines. As well as old rounded lines on original lines.

The brake pedal 100% feels firmer and more solid - i will be doing a track day on Thursday - will report back after.

Good luck!!

Great post!

If you want the brake pedal higher, you can adjust it at the threaded rod/clevis. If you have run out of length the rod could be modified/lengthened

hey duncan - yeah its already at max now - so im going to give it a go on Thursday - and if it doesnt hamper the braking and heeling - then ALLLLLLLL GOOOOD!

      If it (the code) wasn't still current, it should have gone away by itself by now. No, nothing it 10/10. But it is quite likely. Everything else to do with the ignition could still be responsible (which is wires and connectors). The car is an old piece of shit now, so all the wires and connectors are also old pieces of shit.

      Duncan's V37.......race car?

      By Duncan · Posted

      Before I get to the test day, just to finish off the android head unit. This is a demo from car start up....the standard/host system takes a few seconds to boot (same as all v37) but Android comes up quickly. In this vid I'm using the delivered launcher but have set the default to Agami since which is easier to navigate when if use primarily 5 apps. You can see the host system still takes over when required eg putting it in reverse, and you can switch between Android and not by holding the back button 3 sec. It is pretty responsive (fast) but you can see I had to press harder than expected a couple of times.  I still have the phone connected to the stock system, and that also seamlessly takes over Android music playing. v37-android-demo.mp4 The bigger reason that I put this in though is so that I can use Ecutek directly on the head unit. That gives me a dash with logging (up to 20MB only), high and low value warnings on any parameter etc etc. I've run a USB cable from the Ecutek OBD dongle to a USB input on the unit, easy. v37-ecutek-demo.mp4   The unit did freeze on the launcher the other day, I think Agami was trying to verify the license when it didn't have a data connection...will monitor and report back if there are any other problems but so far I'm very happy with the upgrade.
