Please tell us that you have read the oil control thread. If you have no, then you have circa the last 100 pages of it to read before you proceed. No whining, no pissing, no moaning. Just do it.

Yup. Piece of corflute will fix it.

How big are the prizes in your race category?

The only problem is that the Sumitomo caliper bolts don't have any such markings. But they will be a high tensile grade. They have to clamp pretty hard.

I'm pretty sure that there won't be a part number for that bolt. The caliper was supplied to Nissan as a unit. 1 part number. The bolt will have a part number in Sumitomo's system, not Nissan's. it is just a bolt of suitable dimensions and tensile strength for the application. You have one in hand, so you know the exact dimensions that you need. All you need to know is what rating is good for calipers. I haven't ever considered splitting a caliper before - it not being very advisable and seldom necessary, so I've never been in a position to lose on and then have to wonder what grade the bolts are. But if I had to guess I'd suggest they'd be at least 10.9. Probably wise to ask a brake shop for guidance on that.

That is the very definition of a panel beater. I cry and I wail for the state of manual skills present in the motor trades these days. Take it somewhere else, to someone who has hammers and dollys and rolls and straightening benches.

1 psi of boost will make more power than either.

Before off the shelf body parts, people used to repair bent metal.

In a general sense, some R32 parts are usually common with most of the other Nissans available at the same time. Just pull the ones that you have out, pound them flat and anneal them, measure them so you can buy new ones in case it doesn't work, and put them back in.

Plastic plumbing fittings are often available in the right sizes.

I cannot imagine that it is necessary to actually swap the speed sensor. As I said, the speed signal should be exactly the same on both early and late 32s. That being a 0-5v square wave PWM. It's all shown in the R32 GTR manual. It must just be a matter of which pins it's all wired to.

There is an electrical difference. Well, there's no actual electrical difference as far as I know - it's just wiring pinouts. The speed signal out to the ECU is the same PWM. etc.

The more I think about it, the more I think that the best "twin" setup is a v.large turbo + an Eaton screw supercharger.

Oiling mods more important than ANYTHING else.

Just get used to it. To be fair, there are so many questions asked on here that the asker could get the answer for in about 3s of googling. Exasperation builds up quick.
