Engine rebuild: tools required and how to go about it

Well i have just picked up another 6mge and the engine builder i was going to send it to is busy for a few months.
The charges were alittle more than expected, so i was wondering how easy/hard it is to rebuild a motor. I beleive that pulling it apart would be quite simple, but putting it back together is the hard part.
In the process i was looking at having the head ported etc.
So what tools should i be looking at to do this myself and what other tips can you guys recommend?
i have a supra manual but im not sure how specific a 6mge is compared to a 5mge ie. different torque settings??
If infact the pistons are domed i dont really want to touch the bottom end, or should i do the bearings and rings etc?
can any one give me a ball park figure for gaskets bearings and piston rings??
Any other tips? ive noticed there is alot of oxidisation in the cooling system
thanks alot guys!
Glen.
btw, the engine is painted red....is this a sign of anything at all, the under side of the manifold isnt so perhaps an aftermarket thing???

Hmmmm.....you didn't pick a cheap one to start off with, did you?
They are pretty exxy to rebuild. The price on a gasket kit will floor you. Pistons and rings won't be very cheap either. Bearings will set you back about $100. Add to that the machining costs. Reconditioning the head will also need to be considered particularly if you are porting it - a further expense. There's all those little hydraulic doovers in the head you have to test, and then buy if they aren't up to scratch - from Toyota no less......
Personally I wouldn't bother. A running 6MGE will set you back ~ $900, and that will work out significantly cheaper than your rebuild. One weekend's work and you're away.
Tools required depend on how much of it you want to do yourself. A torque wrench is a must, and don't get some dunger from Kmart for $40. Then you will need a range of external and internal micrometers - helps you ascertain whether you need to get bits machined. An engine stand will greatly facilitate assembly, although I just used a raft of milk crates for a few years.
All in all, it's actually not a hard job. You just have to be meticulous. There are plenty of little things you need to do along the way to ensure a good build. There are plenty of good basic engine rebuilding and blueprinting books out there - I really suggest you buy one and have a read before you dive headlong into this.
