Don't need 280's, Danny. Stick with the ones you have. Will spool better and can easily make 500rwkw. The 280's will make power delivery worse especially for the power you are chasing.

Nothing wrong with a T51R - plenty enough for the power you want.

As mentioned above, its been done plenty of times before.

I agree that you should get a 5 bar map sensor and give it whatever boost it needs to make 500rwkw.

Racepace can spin to 8000 on stockers, I, personally have spun to over 9000 on 270's without falling over, the went back to aggressive 260's (custom grind and still think they're too big).

I don't understand this huge duration rubbish where you're rpm is sub 10,000 rpm. Unless you like a peaky powerband, you're going backwards!

Bah, it's not the cams are too big - it's the bottom end is too small :P

A very long time ago I was reading up on cams for a rb series engine. I can remember that most people that used that wasn't happy at all right here on this site. Then ended up swapping therr cams out for the stock set. Some made way more power using the stock ones.

      Should I use rust converter on this?

      By Murray_Calavera · Posted

      The easiest option might be to just spray a bunch of fish oil in there.  At least that way you can feel like you've done something while you continue to ignore it

      I'm firmly on the "zero compliance is good compliance" for FUCAs. I'd be looking to solid metal joints even if the primary reason for having them is because they facilitate the twist in the arm. I have never been more happy with the way the front suspension behaves than I have since I got rid of the FUCA bushes. Even the thin little (short lived) poly bushes in the Whiteline adjustables have too much compliance for my liking. It probably won't be long before I have sphericals nearly everywhere, probably including both top and bottom arms in the rear, and I'll start complaining about the increased costs for dental work. But I will be enjoying the driving more, I'm sure.

      Plus, you'll get great experience in bedding in pads!

      I have offset Nismo brackets so the fact the gktechs can pivot is less important to me. I have 170mm JIC arms with bushings - but they provide no adjustment and I'm not sure whiteline eccentric bushings will fit them (I don't want to ruin the bushings currently in them to find out). Ideally I want something with bushings + adjustment; hence why I'd like to find a pair of these. Unfortunately they aren't easy to find.

      @Vee37 How much do you really care about finding these pads again? If your pads are quiet, work well and produce minimal dust, really isn't that enough? If you are set on finding the exact pads again, I suppose I'd do something like this -  Visit your local Jax, find out what brand of pads they carry. If the Jax workshop you previously went to had the pads on the shelf, then you can almost guarantee it will be of said brand.   I'm guessing you don't have the receipt for the previous work and pads. Can you visit a Jax workshop and see if they can look up your previous job to see what pads were fitted?  Still no luck? Put your stalker hat on, find the staff that used to work at the Jax store and ask them. Talk to local workshops, try to find out where the mechanics went to. Talk to Jax workshops, maybe they relocated to another workshop. When it comes to mechanics, its a small world. You'd be surprised how easy it is to track someone down. If these ideas don't work, shit will start getting crazy very quickly.... You could find out every brand and model of pad that fits that car... and try them individually ticking each off the list if it wasn't the one you were looking for.... If you go down this path your going to want to learn how to swap pads yourself, it is very easy, takes minimal tools and space. If you have room to park the car you have room to swap the pads. Plus you have the advantage of making sure all the brake hardware goes back in so they won't squeal!
