So I'm gonna go over this Wednesday to buy this chicks manual 4G gs , its a hard top and I have an automatic spyder so I'm really tryna use my car for parts and build this new one up.
Can I reuse timing belt and water pump?

What will be needed to pull the engine out?

What's needed to keep a pulled out engine maintained and safe from rust?

looking to build the motor and do a balance shaft delete. Looks simple enough but getting it out no experience on anything like that.

No, get a fresh belt at the least. Water pump, if it's fresh, leave it there. If it's coming out, grab a new one, they're pretty cheap.

Pulling the motor, you'll find step by step guides here somewhere for the GS I'd written in the past a few times over. But an engine crane and some straps/chains, basic sockets, slip joint pliers, 32mm socket (for axles), and time.

Pulled engines don't rust super fast when kept out of the rain. If you're going to leave it sitting for months before touching it, run fogging oil on the final run. It's terrible for all the sensors but saves the engine rusting.

Just remove the rear balance shaft, leave the one on the oil pump. There isn't much gained by the rear one, the front one is the oil pump's damper. Unless you're league racing where you need to be super competitive, to tight rules, and have the budget and time to swap oil pumps as needed through the season, I would suggest it. Street use, guys get away with it, but then what's the point. 5hp becomes small for the loss of reliability. If you're going built motor for turbo use, you'll find how easily you can find 5 or 50hp somewhere else.

I was under impression that the balance shaft is another point of failure for our timing belts.

I was under impression that the balance shaft is another point of failure for our timing belts.

The rear balance shaft pulley has its own belt, which if that belt fails, debris can break the main timing belt. The rear balance shaft has its own gear, and that gear is known to fail (explodes) in high RPM racing use, which will throw the belt, and the debris can break the main timing belt. Same as on 4G63.

The front balance shaft is a damper built onto the oil pump, same as a 4G63. It's known on 4G63 that removing that shaft will reduce oil pump lifespan. Similar idea as to how a lightweight flywheel and lightweight crank pulley cause main bearings to wear quicker. People do both for racing purposes, but neither is good for an engine.
