OK, thanks for you help.
I really want to join you guys on track.
Just purchased a TRD LSD and will rebuilding the gearbox. Obviously now looking into an oil cooler. Already got my chassis mods sorted, so after the above work I should be ready! Nick did very well at 1bar..so lets see how 1.4bar looks on track
Obviously driver skill comes into it too
I have emailed the guy about thermostats and larger row coolers, so will let post here when I get a reply for others that are interested.
Might drop Nick a message about the hose lengths.
Cheers.
