ashloys Posted October 22, 2015 Share Posted October 22, 2015 Hey guys, I'm in the middle of gathering parts for my manual conversion. I've basically got everything I need now except nuts/bolts/oil and a master cylinder! What I want to know is, do the gearbox to bellhousing bolts from the auto box fit the R154? Same with the actual bellhousing to engine bolts. And if any of yous know any other bolts which would fit from my current auto setup please let me know. I've already got pressure plate/flywheel bolts which I got with my TRD clutch/flywheel. They're second hand but in great condition. Should I just replace with new ones just in case?

pedrosixfour Posted October 22, 2015 Share Posted October 22, 2015 The gearbox to bellhousing and the bellhousing to engine bolts are *probably* interchangeable, they'd be pretty standard across all the models I'd imagine. Flywheel bolts are recommended to be changed but I've refitted the original bolts I removed from my W58 several times at this stage, to the specified torque, and I haven't encounter any issues with stretching or pulled treads. I guess it's a matter of opinion but I'd chance them. But I'm a cheap bast4rd! The pressure plate bolts would be fine to reuse as long as they're the correct length and pitch, obviously.

Trust me mate, I bet I'm tighter than you I'm just trying to get a 100% definite answer as I don't want any hold ups whenever I'm doing the conversion and have to wait and order them etc.. so just making sure I have absolutely everything sorted before I start! I got a TRD clutch and flywheel from Mark Luney from a MK3 Supra Type R he imported and they're both in great shape including bolts so I will probably just go with them.. although they're only like $10/20 from Drift Motion and I need to order an electronic speed converter from there anyways??

pedrosixfour Posted October 22, 2015 Share Posted October 22, 2015 Well if you're doing an order to Driftmotion anyway, it might be the prefect opportunity to source a new set of flywheel bolts as you will always be stuck for something when trying to get something done quickly. As for the bolts holding the gearbox, bellhousing and engine together, maybe I'm just lucky, but I have a company about ten minute's drive from me that I can walk into with a sample of whatever fastener I'm looking for and proceed to rifle through their stock until I find it, or the closest thing to it to modify. There is nothing particularly special about the bolts holding the gearbox to the engine. They're fine thread M10 and M12 bolts and of a decent quality (probably 8.8) for sure but apart from that any self-respecting industrial supplier should have boxes of them on the shelves. Certainly no need to order a set from Toyota, at Toyota prices. But like I said the bolts that hold an auto to the engine are more than likely the same as what holds any of the manuals to the same engine.

You're lucky then lol it's weird how no one knows the definite answer! I'll probably just buy them all brand new anyways if I can't get a concrete answer.. they really aren't that expensive form DM anyways. What oil do you use in your R154? Redline? And was yours converted with a MK3 supra box or a chaser/soarer one? Quote Link to comment Share on other sites More sharing options...
pedrosixfour Posted October 23, 2015 Share Posted October 23, 2015 Mine is a later R154 from a JZX90 Chaser. The only thing I needed was modify was the front section of the included driveshaft, which I had shortened and balanced by a company in Dublin. I could've went looking for a MKIII or Soarer driveshaft, but where's the fun in that? I have Fuchs Titan Race Syn5 75w90 oil in there.

Could you please advise me of the company name and the rough cost?? PM if you want I have a MK3 front half of prop but I don't think it fits? I've been told it will need cut/welded/balanced....

Thanks very much I've also found out that if I use a MK4 N/A 5 speed rear half of driveshaft it'll bolt directly onto front half of the MK3 propshaft. Although I assume because mine is a TT auto the diff would need changed too? Probs just easier modifying it if it's only going to be about 100 euro.

pedrosixfour Posted October 25, 2015 Share Posted October 25, 2015 Don't know if the auto diff flange would mate to the NA5 rear driveshaft, you might be lucky. It would be worth confirming as then you'd have everything you'd need to finish the drivetrain. On the subject of the bolts, you could check the EPC for the part numbers of the auto mounting bolts, then, using those part numbers, do a reverse-search on the EPC to check if any of those numbers (and therefore parts) were used on any of the manual spec'd models in the same role.
