It currently has 360nm of torque, I spoke with my parts supplier to purchase it as he is a sponsor and they were well aware that this was a start tune and the car has a lot more potential and assured us that this will suit it, it's ment to be a custom unit but I'm lead to believe it's a standard "800lb" clamping force not the type we require :( so have been waiting a week for a response to see what there supplier says

That would explain it. A stock A15 clutch is 800 pounds.

But of an update.

Fitted cometic 1.3mm MLS gasket kit, arp studs, gt2860rs, new piping, deleted butterfly's from inlet.

Retuning to 20psi aiming for 250+kW
Good fun ahead

Brilliant, Looks like your machine is coming together just great. The combination of all those upgrades will make for a very solid performer.

I'm hoping so as every time I raced it with the h165 I broke the spider gears, gotta break her all in and get back to the track to sort the last few problems then have lots of fun!

Just read through ur original build thread and this one and u have done some magic work on this, I hope it all holds together for u so u can give it a good hiding out there and enjoy the fruits of ur labour. What tread will u be running on it?

I'm running federal 595rsr 195/50/15's atm will see how they hold up, also have some ku36's as spares so will try them out too

What a bloody pile of LOVELINESS. HA HA Well done mate looks sweet.

The H165 and H190 never cut it for me. I twisted spline and broke axles. I hope the r31 works for you.

Skyline R31 used the 9-bolt Borg-Warner M78, which was also used by american V8 Camaros of the 1980s.
