For anyone with a GTR still running the stock twin turbo pipe that's interested - I got a mate to weld a divider into mine, just got it back today and it turned out pretty good....

If you don't know what the mod is all about, it's been fairly heavily discussed over on the UK GTR site, you can check it out here - http://www.gtr.co.uk/forum/84482-testing-m...turbo-pipe.html

They actually sell them from the shop on the UK site, but the shipping is pretty steep and you have to send them back your stock pipe.

Anyways, if anyone wants their pipe done just let me know and i'll give you my mate's workshop details.

Don't know if he's the cheapest around, but I do know he's a perfectionist and the welds are sweet and the cut for the dividing plate is in exactly the right place, apparently took him about 2 1/2 hours.

Interesting mod...

I have some issues though with the thread.

1. No idea how they work out 10whp gains, that borders on the impossible to measure.

2. The graphs are done "by eye", so point 1 even more relevant. Easy to see where 10whp comes from, its all guesswork.

3. But then he didnt "race a flow bench", so why is he racing dynos? :cool:

4. Then they go on to compare 2.8ltr strokers results vs 2.6... on what i can only assume is eye plotted graphs again.

Silly thread in terms of actual testing. It's all "seat of the pants". Conjecture in my books.

They also talk a lot about surging in that thread, so it would seem tuners over there don't know what tuners over here do...

Not many people have surge issues in strokers & GT-RS in Aus. No-one has any issue with surge on -5's either. So whatever they are doing over there is causing their surge problems if over here nobody has any drama's.

Let us know what you think/find after swapping it out though. Im skeptical to say the least at this stage.

Yeah, I laughed at some of the science in that thread too, but linked it in more to explain why they are doing the mod.

Just looking at the way the flow from the turbos comes together at almost 90 degrees in the stock pipe compared to how it looks with the divider, it isn't hard to imagine some gain though, even if only a relatively small one.

I don't know if i'll bother putting it on now though, as I am about to put in a new set of turbos, injectors etc along with a retune, and will probably just swap the pipe over at the same time.

      Should I use rust converter on this?

      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!
