Butters

Can recommend the Frenchys kit, been using it 2 years now with no issue, very happy with it. Only thing for me was upgrading the thermo fan but I am super fussy on cooling. Also interested in electric AC, partly for boot mount to have a clean bay and partly would love the idea of cooling off the car before i get in. The battery setup to do that might be tricky / expensive though. Found this an interesting watch.

Here is as close as we got to a direct comparison(3 vs 4inch exhaust), a tickle more boost, which I am sure was in part due to the exhaust. Made 790 on more boost.

Nope, still smaller rear, put on the 4inch exhaust and picked up power everywhere, ended up just shy of 800rwhp. Didn't seem to be hitting any walls either, so perhaps could have pushed for more but all maybes and the fish that got away etc etc.

Uniclutch install vid, RB Track edition. Highlight reel is very drive able, not noisy but still heavy with the clutch master he has.

I'm not up to date on the latest, but for basic modifications like pod filter, lower springs etc you can get a modification permit at the time of inspection. For more serious modifications you will need engineering. Intercoolers used to fall into the mod permit rule but its been a long while since i looked it up. Either way you will be able to get it registered, just a case of $300 vs $3k .

Thanks for taking the time to post that ! If anything changes or happens please do update us.

Oh and how is the rattle when foot is on the clutch ?

Did you get the sport or track ? From what the documentation says the uniclutch has a small amount of movement to disengage. So your story of tricky pedal setup seems common. Hopefully you got it bled up too, as the bite point moving around is usually either plates wearing in or air in the line.

what car ? what power ? pics ? more details PLEASE

Late to this party but here is your go to shop in perth - https://www.facebook.com/gsautoworksau GTSBOY is on the money cost wise, drive in and out will cost you 15-30k or more. Some items that will save you money - plug in link ecu g4x is much cheaper than haltech. -Pulsar turbo, seem to be "OK" now, never used one myself You really don't have to build the motor, E85, headgasket, studs and a good RB26 will live for ever. Swapping over the twins won't save much as you still need ecu, tune, fuel system etc.

So here is an interesting vid, some proper abuse. What I realised today is the ultra flywheel might mean no adapter ring ! Have emailed them to confirm.

Do need to take it with a pinch of salt. One of the adapter failures, they clearly had setup issues with the flywheel. One of the slipping ones I spoke to and it was pretty clear the throwout was riding, rather than fix, just swapped to a new clutch. These clutches are being put in anything from 5k offroad 4x4 beaters, GR yaris, 500hp commodores to 1200hp barra monsters. Bound to be some issues in some of them when they are not a simple bolt in affair due to the changes in height. There is a lot going on in this picture and unless I did the job myself no way to tell what really happened.

Not yet, might end up being easter now, didn't end up getting time off over xmas. I've been seeing some concerning things online now too. Lots of people with issues, could all be setup issues but the consequences in some cases are significant. All of the below are other peoples stories, not mine and are unverified. Seen 2 x broken adapter ring that destroyed the gearbox as it failed. They still do seem to have twin plate rattle despite claims of silent. Several issues with it not holding power but some evidence of constant pressure on plate. Setup issues with bite point. Lot of people after 2-4 weeks swapping back to another brand. On the positive side, I've seen a barra put down near 1000hp at the wheels and its held it. Also everyone seems to confirm the pedal is light. Does have me a little cautious and looking at ATS carbon clutches again .......

bought it, hated it, went back to mw3.

Indeed they do. Best my diff builder could tell is it's a combination of the different cut/angle and it would seem they lap them in well on accell but less so on decel. He had to use a slightly different pattern to the lap to get the best result noise wise. Also as the rear diff runs in, the whine is getting less. Overall they seem like a good thing so far. He's done a few neat crown/pinion before but all for race cars with loud everything, in most cases the exhaust is louder, so I am the first to notice.... and be somewhat of a pain

So mines not in yet ... which should tell you something ... I got a set of neat gears as well, took a year to get those. Then the setup was a real tricky one, with all the changes. It seems the shims for the front diffs are in short supply and had to wait two round of custom ones. This was all done by a professional diff builder , not me/diy. So here we are about to go into 2025 and I do finally have a built front sump / diff / gears. Just need the mojo to pull out the engine ... Oh as an aside on the neat gears, they have some whine, mostly on decel. Taken a bit of setup again to get that down to a street car level.

just under 600rwkw , 1650cc, pump e85 ~80% duty Your 1200s won't make it safely

Hoping they release an R34 getrag pull type.

I think at this point we need some pictures of the centre

This was a fun watch

Reason I say this is I have seen broken ones, in drift, drag and even behind a stock Z. I do appreciate most of the time its the synchro's that go. Trouble with quoting HP is it doesn't really say how strong the box is. I've not seen many CD00X box's make it past a mid 9(150mph) I have seen about a stock R33 RB25 box's run a 9 too, they all go boom at some point though. Another clue is they make gearsets for CD00X box's too, wouldn't be a market if they didn't break or have a limit people are going past. I totally agree it is a strong box, just have to weigh up the true total cost of the conversion vs rebuilding with a good gearset.

From memory and please correct me if I have this wrong, the nismo that come with half shafts are specific for that diff centre. You may be able to find Nissan ones that match up but you'd need to understand what nismo are doing. Best option is get a pair of 5x1 axles, they usually don't cost that much and direct swap over for the 3x2(6 bollt)

I am using a pull nismo coppermix twin in an r34 getrag box, had both the standard slave and then the nismo one. Adjusted pedal to get bite point how I wanted , it is on the higher side, but would fully disengage past half way down. I also read that the nismo slave won't work but I had no issues with the stroke, might become one later as clutch wears but 2+ years of happy motoring so far. Take the above as one input only, specially as my setup is a bit unique in that I am using an S15 clutch master , cefiro clutch pedal, custom braided clutch line. Lots of variables at play.

So far, based on the maps. Looks like 42 frame size 68mm & 72mm And 45 frame size with 67mm and 73mm

Big claims here. Any links up on the website ?
