Hi guys I have a 2000 GU II Patrol 3.0l and it's done almost 300'000kms and it's still going.
I bought the car in October last year and haven't really done much to it all I have done is the HPD boost controller which is set to run at about 8-10PSI I haven't had the car tuned or anything but if anyone has any suggestions as to mods I can get done to stop it blowing up. I have blocked the egr as well.

I was driving today and it overheated going up a lot of hills and everything. I have an egt gauge but I can't afford a 3 inch exhaust and I don't know how to wire up the gauge. And I don't know anyone who does.

Thanks guys
