Which holes in the block are the oil feeds?

[RustspecS13]

I know it should be obvious, but I don't want to screw it up. It is just an RB20 but its my rb20!

Any way I'm going to try the welding tip trick Ive read about, and I'm going to drill out the oil returns as well.

Other then that I might pick up stuff to make an external oil drain, I'm not sure.

And then I have to make intake an exhaust pipage for my holset, but other then that my rb is ready to drop back in after I rewire the transmission.

I swear this time I'll find my digi cam and take lots of pics!

I'm very lost???

If you have the stock turbo lines just mock them up and you'll see where the oil feed is.

The Block already has a Oil return at the bottom of the block.

If your Holset doesn't have water cooling, then you'll want to plug the water holes in the block. Or you can loop them.Plugging is better, less chance of a leak.

Do you have a bolt stuck in the block??Or are you trying to drill and tap larger ports???
