I've pretty much neglected this thing since it developed a massive oil leak a few years ago. With the Cruiser still off the road, I've decided to start working on it.

After much cleaning, it looks like the front main seal is the cause. I'll finish pulling it apart soon.

So far I've ordered:
GMB water pump
Gates timing belt
OEM front main seal
OEM cam seal
Rocker cover gasket
Sump plug
Drag link rebuild kit

Immediate task is to fix the leak, plus fit the sump with turbo oil drain supplied by @Vee_Que years ago.

I'd also like to replace the radiator, however decent ones are hard to find. An LN106 radiator looks like it should fit, they're the same width but around 50mm taller. The fan and shroud opening are larger too, however the fan offset and clutch diameter are different so this will require some thought.

The L45 4 speed gearbox is worn out. I have a G52 5 speed to replace it with, this will require a trial fit to see what's required for the conversion.

Preferred turbo setup at this stage will be a fabricated manifold and either TF035 or TD04 from a Subaru, probably without an intercooler to begin with.
I'd go bigger dude. My hilux with a 0.48 t3 turbo was barely any more powerful.

How much did you turn the fuel up? How much boost were you running?
8psi, fuel was already adjusted, the egts made it to about 650 towing a heavy load.

Pre or post turbo?
Vee_Que;c-144878 wrotePost. Hence 8psi.
650C post turbo sounds extremely high. Any reason why you didn't increase boost to decrease EGT?
850 is high. Did not increase the boost because I had no desire to blow the motor up.

This was with the Ute loaded with branches, with an 8x5 cage trailer full too and my brother in the passenger seat. Up a long Hill. The rest of the time it didn't go past 400, remember I also intercooled it. It just didn't go that well.
I definitely wouldn't be comfortable running over 500C in the downpipe or 650C in the manifold with an IDI engine.

At this stage I'd like to run about 12psi.
What are you basing the information from though? I couldn't find anything to say 650 was bad, 800 yes.
Not sure how I feel about this. I hope it doesn't turn into a kettle.



Also received the other parts.
Id be more scared of a GMB pump than I would of that.
What's wrong with gmb!? They are oem for lots of Japanese vehicles.
Oh well, it's the wrong pump. Snout is too long, so the pulley won't line up.
bugger.
I reckon that 'oem boxed GMB' is different to 'retail/consumer GMB'. At the very least, this appears to be the case on some of their offerings.
Looks like I've been sent a T57 pump and I require a T18. Have also arranged a correct cam seal.
Neato. As long as you've got it sorted and the head scratching can stop. :)
a month later
Taking the radiator to a dude tomorrow to see if it can be recored.

If not, Adrad do a core and end tanks but not an assembled radiator.
