Thread: Some advice on wiring etc on 4wd vehicle

Mate that's the idea. All of those vintage trucks with cast blocks and alloy heads suffer the same thing.
Too many heat cycles and the head gaskets go.
Hope the timing chain, adjuster and guides were ok but can be done with the head on I think.
Make sure the fan clutch works properly too and fit an aftermarket temp gauge. The oem ones are notoriously slow to read high levels
They go pretty well.
If it's the electronic fuel pump you cant do much to that side of it, if mechanical there is a couple of tricks.
Big one getting some more boost.
Some washers behind the wastegate mounts can get them up to 15psi pretty easily if it isnt there already.
Mine had 4 tops.
Egt gauge is pretty important too if you start to get cranky

Yea I didn't replace any of that as it had all been done at 200 anyhow, and yeap would be able to do it with head on, could have damn near done the head gasket with the engine still in the truck but I couldn't get the rear head studs out so slipped it off the bellhousing, unbolted the downpipe and pulled the whole thing forward while I had the old radiator etc out and had the room, saved taking it right out, whether that was the right way to do it or not I'm not sure but I got there in the end. Aim is not to spend a tonne of money on this vehicle but at the same time want a reliable rig that's capable of being a hunt taxi in most situations. I'm currently eyeing up tyre options for it, I have a rear spring lift kit for it and with the torsion wound up and ball joints flipped I reckon it would have plenty of room to run an aggressive 32, it would probably run them as it is but may run into problems with certain steering and flex angles in the front, the tyres on it currently are the good old Kumho KL71s (31s) but they're at the end of their life, had a set on my hilux a few years back and was really impressed with them on and off road, were nice and quiet on the road and very good manners for an MT but damn they wore quick!
