My Class 8 Extreme 4WD MK Patrol

[Steve879]

Hi guys,
Thought i would give you guys a bit of a rundown of my Patrol, its a 1985 MK patrol, Originally a L28, now runs an Injected 308. I race in the NSW Offroad Racing Championship, i plan this year running 4 events, Crookwell, Griffith, Milbrodale and Colo.

I bought the old girl as a half built race truck in 2009. I was just starting to build up a MQ from stock when i stumbled onto this one, it already had the Carby 308 installed and the cage was in but not certified, seats where in but thats about it.

My first race was at the Australian round at Griffith in 2010, this was also run as a NSW round and that is what i entered, the car went well until during the first lap on the sunday the front diff cover seal cracked and we lost oil, resulting in blowing the front diff, we removed the tail shaft and got going to only 500 metres later rip the front brake line of the car and lose all brakes, we managed slowly finish the lap with only some rear brakes and that was out first race!!

Race 2 was a disaster, this was Warialda 2010. The car from the moment we took it off the trailer had issues, the major being overheating, the second was just the unreliable Holley that was on the car, we ended up blowing the radiator up! but managed with a bit of bush mechanics to get a bt more racing in before packing up and heading home very disapointed!

It was the this point i decided that a major upgrade was required and this is where began the upgrade to injection, as well a better cooling system. The cooling system was first and we ran Crookwell 2011 with the radiator and fan setup and it was a massive improvement, no longer was the car running hot, it would run hard all day and not have any cooling issues, the race though was the last straw for the Holley, it caused us issues all weekend and stopped us completing full race distance. I came home, pulled the Holley off the car and put it on ebay!! then once they were gone i went about finding the injection kit and working how it was going to all work! After a bit of study i found out that the injection top end is a straight forward bolt on to the old school 308, mine being a 1974 example, i found a kit and went about fitting it up.

We raced at the 2011 Milbrodale Mountain Classic in August, the Patrol was now injected, the cooling system was done and i also had dropped from 33 inch Claws down to 31 inch Mickey Thompson MTZ's. The car was fantastic, other than a broken engine mount needing some welding, the car all weekend against some tuff competiton in the Extreme 4WD class, in the End we won out class, a top effort and was very happy after all the hard work i had put in. That is pretty much where the car is now.

Im in the process of some upgrades for this season, i have a brand new Pair of 2.5 inch Remote shocks for the rear and are moving my Fox 2 inch remotes to the front,so will have dual 2 inch with a Hydraulice Bump stop on the front, and the 2.5 inches on the rear, i also have new front shackles coming, and im about to change the front diff as i bent it having a little test at my mates property, ill post the video as well!!

My next race will be Crookwell in April. If anyone is interested in coming out and you live in the area, let me know and ill tell you all about where it is!

Ill keep on updating as i change and break things in the Future!!

Gday mate welcome aboard great lot of build pics awesome looking truck mate

[Silver]

Crikey, Steve, the best thing I've seen to come out of Canberra for a while!! (Just stirring)

I like your idea of simple bolt on injection, just remove the valley and heads, and then you can make a start :-)

Warialda is a fair hike to have mechanical issues, feel your disappointment there :-(

Thanks for sharing.
