So I'm home after the big matsuri weekend.

It was all going great, not the greatest weather, especially on the Saturday, until I went out for my second round of runs on the Sunday and .... BANG....

Yep, blew third gear. Not the best result, but I had a feeling the gearbox was the next weak point. Changed the oil at the track and a LOT of metal came out. Seeing as I drove the car there (4.5hr drive) I had to decide weather or not to take the chance to try and limp home. I did, and it managed to without any dramas, however the box clearly still has some broken bits in it. Got some amusing looks rolling through towns with all the gearbox noise :P

Anyway, here is a video of an average run from the Saturday, I will sort through my videos from first session on the Sunday and see if there is anything worth putting up.

I thought 25 boxes were pretty strong bits of gear :)

That's what I keep getting told :P

I suspect that age was probably a factor, the car has 160,000kms on it now and as far as I know it was the original box.

Looking into the cost of a new box, not real keen on a second hand one. Also what's peoples opinions of getting it reco'd, and also options like straight cut gears? I don't know a great deal about gearboxes so any info would be appreciated :)

Update into fixing the car: I have decided I will most likely buy a brand new gearbox from RHDJapan because it will be about $2200 delivered, cheapest new price I have found in Australia is $3100 delivered. I will be pulling my old gearbox out in a couple of weekends, was away last weekend, will be away this weekend, so hopefully the next lol. I will pull it apart and take pics to show everyone the damage. Once I have it out I will order the new one (also gives me a chance to pay shit off my credit card so that there is enough free on their to pay for the new box haha.

Pulling gearbox out tomorrow. Will open it up for a look and post some photos.

I'm really struggling between buying a new box or saving a bit longer and upgrading gears, then I 'should never have to worry again'. Lol.

If anyone that has seriously looked at the options before could jump in and let me know any info would be greatly appreciated.

Well the gearbox was pulled out last Saturday as planned. I still have no fully opened it however, there seems to be limited info out there and I am just winging it. I am currently stuck at the selector. I have knocked the pin out but it appears to be a collar, I'm told the proper name is a 'roll pin' lol still holding it in so I've got to get a punch for that then hopefully I'll be on my way to opening it :P

Yep. I'm surprised I made it the 400km drive home haha. Every gear has marks on it though.
Simply because of current financials, I have ordered a brand new gearbox from RHDJapan. I wanted to buy local but the markup was about $1000 and those I spoke to wouldn't budge on price. It should be here in 2-3 weeks then I'll have to find time to fit it and get it all run in before some hill climbs events. I would have loved to have gone straight cut gears but again current financials just won't allow it and I'd prefer to get the car running again for now.

I would like to go PPG straight cut synchromesh gearset but I'm just too stuck for funds at the moment. I will run with the new box for a while and just see how it holds up for now. I know it won't be a problem with hill climbs etc which will be main focus over the next year. I hope to attend the November Wakefield matsuri again so I guess that will put it to the test and I will be 'trying' to be more sympathetic on the box after some advice from a view. If I brake a gear again I will not be wasting my time doing anything other than going stronger. We will just see how it plays out I guess :P

You will be right mate ;) Mine has held up for a fair while and my kms are about the same as yours was so a brand newy should last for ages!

    • The average previous owner for these cars were basically S-chassis owners in the US. Teenagers or teenager-adjacent. I often tell people that neglect is easier to fix than something that was actively "repaired" by previous owners.
    • Update 3: Hi all It's been a while. Quite a lot of things happened in the meantime, among other things the car is (almost) back together and ready to be started again. Things that I fixed or changed: Full turbo removal, fitting back the OEM turbo oil hardlines. Had to do quite a bit of research and parts shopping to get every last piece that I need and make it work with the GT2860 turbos, but it does work and is not hard to do. Proves that the previous owner(s) just did not want to. While I was there I set the preload for the wastegates to 0,9bar to hopefully make it easier for the tuner to hit the 370hp I need for the legal inspections that will follow later on. Boost can always go up if necessary. Fitted a AN10 line from the catch can to the intake hose to make the catchcan and hopefully the cam covers a slight vacuum to have less restrictive oil returns from the head and not have mud build up as harshly in the lines and catch can. Removed the entire front interior just shy of the dashboard itself to clean up some of the absolutely horrendous wiring, (hopefully) fix the bumpy tacho and put in LED bulbs while I was there. Also put in bulbs where there was none before, like the airbag one. I also used that chance to remove the LED rpm gauge on the steering column, which was also wired in absolute horror show fashion. Moved the 4in1 Prosport gauge from sitting in front of the OEM oil pressure gauge to the center console vents, I used a 3D printed vent piece to hold that gauge there. The HKB steering wheel boss was likely on incorrectly as I sometimes noticed the indicator reset being uneven for left vs. right. In the meantime also installed an airbag delete resistor, as one should. Installed Cube Speed premium short shifter. Feels pretty nice, hope it'll work great too when I actually get to drive. Also put on a fancy Dragon Ball shift knob, cause why not. My buddy was kind enough to weld the rust hole in the back, it was basically rusted through in the lowermost corner of the passenger side trunk area where the wheel arch, trunk panel and rear quarter all meet. Obviously there is still a lot of crustiness in various areas but as long as it's not rusted out I'll just treat and isolate the corrosion and pretend it's not there. Also had to put down a new ground wire for the rear subframe as the original one was BARELY there. Probably a bit controversial depending on who you ask about this... but I ended up just covering the crack in the side of the engine block, the one above the oil feed, with JB Weld. I used a generous amount and roughed up the whole area with a Dremel before, so I hope this will hold the coolant where it should be for the foreseeable future. Did a cam cover gasket job as the half moons were a bit leaky, and there too one could see the people who worked on this car before me were absolute tools. The same half moons were probably used like 3 times without even cleaning the old RTV off. Dremeled out the inside of the flange where the turbine housing mates onto the exhaust manifolds so the diameter matches, as the OEM exhaust manifolds are even narrower than the turbine housings as we all know. Even if this doesn't do much, I had them out anyways, so can't harm. Ideally one would port-match both the turbo and the manifold to the gasket size but I really didn't feel up to disassembling the turbine housings. Wrapped turbo outlet dumps in heat wrap band. Will do the frontpipe again as well as now the oil leak which promted me to tear apart half the engine in the first place is hopefully fixed. Fitted an ATI super damper to get rid of the worn old harmonic balancer. Surely one of the easiest and most worth to do mods. But torquing that ARP bolt to spec was a bitch without being able to lock the flywheel. Did some minor adjustments in the ECU tables to change some things I didn't like, like the launch control that was ALWAYS active. Treated rusty spots and surface corrosion on places I could get to and on many spots under the car, not pretty or ideal but good enough for now. Removed the N1 rear spats and the carbon surrounding for the tailpipe to put them back on with new adhesive as the old one was lifting in many spots, not pretty. Took out the passenger rear lamp housing... what do you know. Amateur work screwed me again here as they were glued in hard and removing it took a lot of force, so I broke one of the housing bolts off. And when removing the adhesive from the chassis the paint came right off too. Thankfully all the damaged area won't be visible later, but whoever did the very limited bodywork on this car needs to have their limbs chopped off piece by piece.   Quite a list if I do say so myself, but a lot of time was spent just discovering new shit that is wrong with the car and finding a solution or parts to fix it. My last problem that I now have the headache of dealing with is that the exhaust studs on the turbo outlets are M10x1.25 threaded, but the previous owner already put on regular M10 nuts so the threads are... weird. I only found this out the hard way. So now I will just try if I can in any way fit the front pipe regardless, if not I'll have to redo the studs with the turbos installed. Lesson learned for the future: Redo ALL studs you put your hands on, especially if they are old and the previous owners were inept maniacs. Thanks for reading if you did, will update when the engine runs again. Hope nothing breaks or leaks and I can do a test drive.
    • No those pads are DBA too  but they have colors too. I look at the and imo the green "street" are the best.
    • I’m not sure what happened I told them about sonic tunes free OTS tune and the next the I know .. I was booted..   To funny
