What ended up being my go-to method was using a seamstress tape which I would hold in place using a welding magnet. The bolt idea was quickly discarded for exactly the same reason you mentioned.

It does have tons of useful information, hopefully I can get a translated version of it soon as that would help take out a lot of the ambiguity here. For example, what measurement gives me the frame rail width? Is it #9? Maybe, but it doesn't really show a location for measurement points on...

I think I am definitely going to reattack it in an attempt to get it perfect. It does bother me the way it is right now. On the bright side, I found a spec sheet.However, it is in Japanese and it's not of the best quality. Hopefully I can get it translated and then decrypt the drawings. Spec...

The issue I have with measuring the re-bar to get the frame rail width is that the rebar is extremely flexible. It has a springy effect to it and when not on the car the mounting points actually tend to spread apart. Like you suggested previously, I am trying to track down a frame spec sheet...

Cowl Repair As I contemplated the issues with the front core support, which I discuss in my previous post, I also began working on the driver (right) side cowl repair. GTRs are notorious for the cowl rusting through as water becomes strapped between the metal cowl and the plastic cowl that...

Core Support Replacement Was able to do more work today and the body fitment is looking pretty good. I really can't complain. I actually met up with a few buddies and took photos and notes off their GTRs to make sure I was on the right track. Realistically, the gaps and fitment on my car at the...

What are you suggesting I measure? The front cut I bought was just the leading edge of the shock towers forward. So once I removed the core support it was all disassembled. The only remaining piece is the core support.

I'll see if I can track a spec sheet down, that would be helpful. As far as putting the car back on it's wheels, that won't be happening for a pretty long time. My garage floor is flat though, so I could level the car out and then measure from the floor up. However, it is the width between the...

From what I can tell the rails are undamaged and straight.

Core Support Replacement Was able to do quite a bit of work today on the car. Ground down all the spot welds I drilled out and also ground all the flanges where the core support mates to the chassis. So the prep work to get it welded in place is coming along fairly well. Once everything was...

I have TIG welder that I have been learning with. Thanks for the link, I'll check it out.

Makes sense entirely. What's your suggestion regarding how to spot weld the car? 1. Fill in all the holes on the chassis first, then repair the core support, then drill only necessary holes in the support to be spot welded? 2. Just fill all the holes in the chassis then weld the core...

I like the screw idea. I was trying to avoid punching holes in the car as much as possible. But that may be worth it for the sake of a tight fit up. I had originally intended on using quite a few clamps to achieve the same effect. Also, I was considering whether I need to put all the front...

1. I did send the block to a machine shop. I will assemble it at some point in the future. I am doing a bunch of headwork and it will then be sent to the machine shop once I'm done. When I get it back I will assemble everything. 2. I don't remember the brand. I bought it off Jegs or Summit...

Core Support Replacement One of the issues with this car is the core support was damaged in an accident. The damage is not too horrible, but it is slightly misshaped. Additionally, someone hacked up several mounting holes on the core support, though I am unsure why. I didn't think the old...

Engine Work It has been a substantial amount of time since an update on this thread. Unfortunately, life has kept me pretty busy since last year, but back to making some progress. One of the projects I have been doing to keep myself busy is working on the engine. I've spend some of my free...

These are all good points. I guess I had intended to run it more in the 110-130 range or so, and regulate it down to around 100 PSI. Regardless, I did throw the times into a CFM calculator last night. Up to 100 PSI the pump is averaging 18.42 CFM, and at 130 PSI it is averagin 17.85 CFM. The...

That's good to know. I know it was hardwired when I bought it, as it was used commercially. However, I asked that question when the electrician was putting in the circuit for it. They had said it wasn't necessary. Fingers crossed they were right.

Ok, I'll try that.

Looks like some sort of adjuster. Which is which then?
