    Hello, A forum member has sent us his 'RS' diff sent from the US. He's requested a bit of a thread of what we do, so thought I'd take the opportunity to post up here. As is fairly common knowledge, the US rear diffs are setup "soft" from the factory. We reset them to be the more aggressive factory-intended RS setting. This thread serves as a "here's what's involved" and could be used as a how to (at your own risk, and as a supplement to the factory manual). First things first we check a few things out with the diff itself. A bit of wear was evident from the swarf on the magnet. Not overly concerning, as it is a clutch plate LSD unit that does wear down by design. Backlash felt alright by hand so we went straight to checking preload and mesh pattern. Preload was on the low side (0.1-0.2nm) so I expected a bit of bearing wear. Mesh pattern was indicating that the crown wheel and pinion had reasonably full contact so I was happy to proceed. A bit of wear was evident on the small pinion bearing which may explain the low-ish preload reading. Once the unit was disassembled, the components were thrown through the spray wash for an initial clean. We then crack tested the crown wheel and pinion to make sure it will run reliably into the future, and to make sure it's suitable to process further. After this process the crown wheel and pinion are demagnetised and then ready for further processing (in this case, shot peening and isotropic super-finishing). It was now time to move on to the LSD unit. Undoing the screws can be tricky without the right tool - they are sometimes extremely tight and easy to strip. We use an impact screwdriver to easily undo the 4 small m5 counter-sunk screws. From here the unit disassembles into its components easily. Take note of the positions of all the items, specifically which hemisphere goes on which side of the carrier so as not to change the ramp settings. We use texta marks and scribe marks for this. Each hemisphere has a clutch pack comprising of 2 clutches and 3 plates. The US models order these incorrectly to give a soft breakaway torque action, so as to not induce "unsafe" oversteering characteristics. From the US they are ordered PPCCP, whereas they should be PCPCP. The correct ordering gives almost twice the breakaway torque. Incorrrect: Correct: While we have everything apart we check for scoring etc. on the plates and clutches. This one is in good condition. Sometimes the tags on the plates bite into the housing and cause all sorts of issues. This needs to be corrected by filing the housing back to a smooth surface, and then replacing the clutch packs. The next check is that we have an even stack height on both hemispheres, to give an even breakaway value from left to right. This is often overlooked but makes sure it operates correctly and wears evenly. In this case the variation between the two stacks was 0.01mm - about as good as you could possibly expect! The plates and clutches showed zero wear so this was driven by a very conservative driver or for a short time. Now it's just a matter of reassembling with a good oil, paying attention to your marks.

    Been a while since our last post! We've seen stacks more Evo X drivetrains through the door recently, not tot sure why. Maybe it's that they're getting to that age (some are 9 years old!) or just an increase in business. Here's a fresh transfer case from an X getting a RalliArt front diff, and shot peened and ISF micro polished gears.

    Now I know a lot of people believe these twin clutch gearboxes are as fragile as glass, but this is not completely true. In theory, the gearset and gearbox casings are extremely tough and should be able to handle up to 1000hp with no need for upgrades. However, there are other areas of the gearbox which leave a lot to be desired. I will go into further detail regarding these areas in other topics, but here I will discuss some of the issues associated with the Mechatronics unit, or more specifically - the valve body. As with all automatic gearboxes, the TC-SST uses a fluid control system to move clutches, shift forks and cooling fluid to the clutches. When the valve has problems, it can catastrophically effect the operation of the gearbox and cause multiple other parts failures inside the box. The valve body core itself is of cast aluminium construction, machined to create the bores and surfaces on the unit. The bores contain valves that are operated by electronic solenoids on the TCU half of the Mechatronics unit and these valves are machined hardened steel. Issues arise when material becomes caught between the valve and the bore, which has the ability to either damage the soft aluminium bore - causing leakage - or jamming the valve in the bore which causes a whole host of other issues depending on the particular valve in question. Maintenance is a huge factor in lifespan of valve bodies, as reducing the chance of damage to the valve body from stray materials will obviously statistically reduce the chances of valve body failure. For this reason we recommend changing the fluid and filter every 20-30k km maximum for street cars and 2.5-10k km for hard driven cars or race cars. We had a car come in that we had performed a build for, including a 10 plate custom clutch setup and Kozmic reconditioned shift fork 4 - however we had found no reason to modify or replace the existing valve body as it was performing well and holding pressure prior to the build. The car drove well for a period of time before the owner contacted us and advised us that the car had become almost undrivable and lost even gears. We knew the shift fork was not responsible for this, so we received the car and began testing the valve body for failure. It became apparent that a valve had become stuck, causing the car to lose even gears - but more concerning was that the valve we found stuck was also causing the odd clutches to not properly disengage. The car was driving in 6th at 110kmh on the highway when the failure occurred - thrashing the car did not cause this failure. As you can imagine - having the odd clutches partially engaged while the car is in 6th causes significant heat and will eventually destroy the odd clutches. Here is a photo of the Mechatronics unit complete prior to inspection: Here is a photo of the valve body completely disassembled for inspection, including valve removal: We had removed the entire gearbox in anticipation of finding destroyed clutches, and boy did we ever. The even clutches remained in perfect condition, however, the same cannot be said about the odd clutches.... I'll let the photos speak for themselves: We have seen many, many different failures from Mechatronics units and I will endeavor to keep this thread updated with the different failures we have found over the years. If you have any requirements for your Evo X, whether it be a manual or SST, feel free to contact us anytime to see what we can do for you!

    Hi guys and girls, We know that a lot of VIII and IX owners would love to keep their 6-speed gearbox but are often let down by the relative lack of strength compared to the 5-speed cousin. They're nice to use but unfortunately don't put up that well with 250kw+ that many of these cars run. The only solution has, up until now, been to "downgrade" to the older, more reliable 5-speed. Well, we have been working on a solution. We've built a couple of these now and they're running reliably in track oriented cars and performing very well. We start with an Albins helical replacement gear set for 3rd, 4th and 5th. These are only available to builders, not to the general public, for reasons I will explain later. (Albins left, stock right) They are a coarser tooth profile with a narrower helical angle, meaning better strength (Albins bottom, stock top). The design also eliminates the strange OEM thrust ring arrangement on 4th. This leads to better support on the shaft, less flex and so on. Made right here in Australia to Albins' usual excellent quality. We then shot peen and ISF the lot. comparison of stock vs. ISF treated Albins (ISF Albins bottom, stock top): We build them to our specs which we keep close to our chest. These are highly customised items and run clearances that are controlled via a sequence of shims on the countershaft. They are not "drop in" items, hence not really sold to the public. We have also made some stronger synchroniser springs to replace the ones prone to breaking and causing gear lockout. And finally, we had a bunch of testing done on the 5-6 hub and sleeve which can be problematic. We thought that we might be able to improve the hardening. The results from the metallurgist were surprising - there was little improvement to be made (none, in fact), by further heat or chemical treatments, including cryo treatment. Their suggestion was that some fatigue resistance improvement could be gained by shot peening the hub and sleeve carefully to prevent burring - which we do in-house. We think we have addressed the key issues that these gearboxes have. So here's the clincher. I need to order 10 sets to get Albins to do a run. They did a run of 10 and I bought a couple, the rest went to the States, so they are sold out and back ordered. I'm looking for an expression of interest to put these back into production. Price fully built in your box is $4,600 including GST. This includes all of the following: - New Albins 3rd, 4th, and 5th gears - New synchro springs (upgraded in-house design) - New 5-6 hub and sleeve - New genuine bearings and seals - New genuine 3rd, 4th, 5th and 6th synchro rings - New roll pins and clips - New Dimple magnetic drain plug - Crack tested shafts and gears - Shot peened to SAE standards all gears, hubs, sleeves and shafts - Isotropic super finished (ISF) all gears, hubs, sleeves and shafts - Chemical clean components - Bead blast case - Built to Neat Gearboxes' exacting specs - 1 year unlimited km warranty (some conditions apply for high powered, track orientated cars) - Shipped anywhere in Aus at no extra cost with full insurance (you just need to get it to us) This box is every bit as strong as a strengthened 5 speed. It is not bulletproof (what is?), but is extremely reliable. If you'd like to put an order down, I need a firm commitment. Production will be 3 months away so it won't be until the new year. I'd like to gather a list of anyone who is actually interested in this option and we will work out the details such as deposits and timeframes once we know if we can get it off the ground. Post up, call or email us if you are interested or have any questions. Sam: 0407 698 682 info@neatgearboxes.com.au Cheers guys.

    I have been looking for a budget dump and front pipe. Yesterday I made the mistake of visiting Ivan. He showed me his twin dump and I immediately started drooling. Love at first site. I told myself it was out of my budget and went home. I tried to distract myself but couldnt stop thinking about my precious. I shook all the piggy banks I had and shot down and picked one up later in the afternoon. I have spent plenty of alone time with the pipe and still in love with her every bit as much as when I first saw her. My girlfriend tells me to stop touching it but I can't help myself. Thanks Ivan for the time you spent with me yesterday, the great service, and possibly ending my relationship with my better half. Who needs a GF when I have my precious anyway.

    Hi guys and girls! Some of you already know us and what we do. Here's a little intro and history for those who don't know. I've personally been a part of this forum for a while and ventured into starting my own business on the Evo platform back in 2014 and we were lucky enough to secure an awesome shop at the end of 2015. The business has since spread out a little into other Mitsubishi's and older evo's too, but our primary platform remains the CZ/CY/CX. We do all major work including tuning on Ralliart Colt, Pajero and Triton models too. We have very close business relationships with a number of shops in the USA, including ETS, MAP and Kozmic, being our sister shop. We are Australia's only licensed installer and distributor for all Kozmic products and had the privilege of being invited to the USA by David and Eric for a one on one technical conference for all things twin clutch. Needless to say we have picked up a whole host of tricks and secrets on our 12 day stay with Kozmic. Here are a few photos of what's been happening recently at Boostin' Juice Performance and we will be keeping you updated on what's in store for the future!

    Hey everyone, We’re an Adelaide-based workshop specialising in gearbox and differential repairs and modifications. That’s all we do - we don’t even service cars. The main thing that sets us apart from other workshops is some of our in-house gear strengthening technologies. We shot peen gears and shafts using SAE guidelines (J2441). SAE tests show that shot peened gears exhibit a 30% fatigue resistance improvement. If you're interested, have a look at our short explainer vid here: We also have isotropic super-finishing (ISF/REM) facilities. This process produces a non-directional mirror-like finish on gears. This finish leads to friction reduction, lower oil temperatures across all torque ranges, and improved strength. Customers with dog engagement gearboxes also report smoother shifting. On top of these two improvement processes, we have crack testing facilities, spray washes, hot tanks, bead blasters and so on. Assembly is carried out in a dedicated clean room, using calibrated precision measurement instruments to make sure setup is perfect. We’re really proud to support the Evo community and look forward to answering any drivetrain questions you may have.
