late 97 on hilux 3rz turbo conversion walk through

[BeRad]

It depends on the turbo and the oil feed hose you use, i used a -6 on the 3rz becuase i had it lieing around, -4 is probably best for oil feed, bush bearing turbos dont need restrictors as much, ball bearing turbo's require less oil so a restrictor "should be used". -10 hose should be used for oil drain so no pressure can ever build up.

The oil pressure sensor, is under the exhaust manifold, its a mushroom shaped sensor about 20-25mm in diamter.

When i put my oil drain in i drained the sump, got a fire extinguisher on the ready, covered the 16mm drill bit in grease, and drilled very slowly so it didnt throw shavings into the sump, the grease grabs the shavings before it can go in, and then spent about half an hour checking and checking and checking that nothing had fallen into the sump and its baffling, I then welded it a bit at a time as not to produce to much heat. I put the drain toward the front of the sump.
If your going to tap the sump, you'll need to weld a "pre tapped socket" to the sump and drill a slightly bigger hole in the sump than the threaded socket, the sump is not thick enough alone to tap.

A quick solution as gearboxs go, the w56 will take a bit of a battering, a w58 from the supras is another option that is alot cheaper than a 154, and somewhere in between the 56 and 154 in strength.

Imo, id leave the w56 if and when you break it have a w58 sitting there to changeover.

I'm not sure if I'm missing something here, but you're willing to risk the integrity of your engine with some metal shavings instead of spending $20 max on a tube of gasket goo?
You thought about unbolting the sump off the engine whilst the engine is still in the vehicle?

That way it can be properly cleaned, properly welded, properly drilled, etc.

Its not the $20 for gasket goo, its the fact that I can't be buggered pulling the whole engine out or the gearbox out to get the sump out Or, if as Berad has said, I use grease on the drillbit and drill damn slowly, I can get the whole in there without the pain of removing anything... Just trying to keep things simple, and no simple does not necessarily equal bad.

There must be 2 diff types of sumps then cos mine you dont have to remove the gearbox to get it off. Even my haynes manual says nothing about pulling the gearbox out

[wagonist]

And if the 3RZ is the factory motor, I severely doubt that you have to pull the engine out to get the sump off either.
It may need to be jacked up off the crossmember, but it won't require removal.

Its not the factory motor, it is a transplant into an ealier hilux, and it is a 4wd, so the front diff is directly under the sump, not allowing it to be removed. Since the sump holds the oil at the rear of the sump, it needs to be taken off towards the rear of the vehicle if the engine is in place, and the tranny stops that happening. It could be taken off underneath if I remove the front diff, steering stabiliser and every other bit of junk under there but no thanks The other option is to lift the motor out... or do it while its in place

Without pulling the box off i could not see a way of getting to the 3 bolts at the back of the sump, either way not pulling the sump off is dangerous as you've said but thats how i did it and warned others of the dangers.

It wasn't clearance issues to the front x member, it was getting to the back few bolts because of the bellhousing.

Fingers crossed my hilux will be hitting the streets this arvo

[{Mr Crabs}]

I always thought the sump thing was for 4WD as the sump is molded to the shape of the fixed diff.

I got a new gear box around the same time as the turbo and left the sump on.

I am still thinking of removing the 3RZ in place of a JZ.

yer, although the 3rz is different and just as capable, its always better when someone asks what it is and they dont know haha.

There is good news and bad news. Good news I cracked the 200rkw mark only on 10psi and there is still room to improve on the tune. Bad news the clutch is dead and even worse fucking news is iam fuckin unemployed

[BeRad]

albion brake and clutch, $600 500hp 5puck thats driveable, unemployed = lots of dole cheques to get it.

[Tweak]

UNemployed and no clutch/car means sell everyting thats not bolted down and even attempt to sell the stuff that is.
Got a number for albion brake and clutch?

Here are the pics. Was in a hurry
