I see. There was a semi-circle shaped cover on the R150 bellhousing that was bolted to the bottom ~third of the front opening with 4x 12mm bolts. It covered what was otherwise exposed below the engine block. Not sure what the exact name of that is but will I need one of those too?
I am not familiar with what that looks like. Can you give me the year and model type the R150 trans came from? We can look up the exploded diagram for it in Partsouq and what you're describing should be represented visually there.
Got another question regarding the input shaft. From what I've read, the input shaft for the '96+ R150 is 1/8" LONGER than the input shaft of the R154. Is this enough to cause a problem where the bellhousing won't actually mate to the engine because the input shaft bottoms out inside the crankshaft?
It will mate just fine, there is extra space behind where the input bearing sits in the crankshaft, both the ar5 and the r150f long version fit without trimming although some people trim the ar5 anyways if I am remembering right as it is a little closer to bottoming out.
That's relieving to hear. Well at this point I have everything I need except the pedal kit...ordered 3 weeks ago but Driftmotion is super backed up due to California's stay at home orders. I'll be sure to document how the swap goes when the time comes to assemble and install everything.
Since it seems that the dimensions of the R150 with the 1JZ bellhousing are almost the same as the R154, is the information in this thread (https://www.clublexus.com/forums/per...tension-2.html) applicable to me for getting a shifter/extender? I'd prefer to use the automatic hole, but I'm not afraid to make cuts if necessary.
That's some good info right there you are looking at the right posts, 99sc42 posts great info.
I wouldn't suggest trying to bring it out of the automatic hole, but that is just me.. it can be done but really it is too far back.
What I would do in your situation is option 3, if that wont bolt on then option 1.
option 1: copy the 92-94 setup, make a new hole closer to the console, and with the smaller extension (~2") and you use the older shifter with a swan bend in it, basically like an early 1jz r154.
option 2: imitate the 95+ setup, make the hole closer your auto hole, you use the 4" extension and a shifter that is straight up and down, without the bend.
This is a similar position to the 95+ remote shifter location, but you wont have the height of the remote shifter setup to need the newer tunnel.
I don't always like this option cause the extension is pretty large just to have an up and down shifter so far back.
option 3: I want to say the guys doing the ar5 swap and using that JDM extension housing that bolts on... that might even bolt up to the r150 and be just about the right length, with a straight modern OEM shifter. I would think that would have the best shift feel also since it is an oem housing/extension/shifter, but either way would work if you just have a shop extend what you got.
*edit* part number: 33570-22150
check out this thread for pics, bolt pattern looks the same as 2wd r150 but as far as I know no one has tried to bolt anything onto that trans extension wise. https://www.clublexus.com/forums/bui...ml#post9063073
Interesting. I'd actually never seen 33570-22150 before. The bolt pattern on my R150 matches the one on the left (5 1/2") from top hole to bottom hole). I'm assuming that since the 5 1/2" pattern is for JDM R154 or AR-5 that a 33570-22150 is also the same pattern but I'd like to confirm. I've searched but I cant find any actual measurements. Also, kind of a stupid question, but how does the 33570-22150 work? I'm looking at pictures of it and it seems the linkage piece inside the housing has the same ball and socket thing that a shifter would normally have on the bottom of it...?
*edit 1* Looks like it is fits the longer bolt pattern: https://www.toymods.org.au/forums/th...fter-positions.
*edit 2* Would I need to get something like part #33252-22030 with the ball joint on it?
^^ I didn't know the R154 Tripod and AR-5 transmissions had a different top shifter bolt pattern compared to the older R154's. Good to know.
FYI the billet housing on the right that is for the US MKIII Supra R154 and JDM Supra JZA70 R154 (both "top-loader" extension housing non-tripod designs) is also the same pattern used for the JDM 1991-1993 Soarer JZZ30 "top-loader" R154's with factory extension housings. I think XCessive Manufacturing's aftermarket R154 extension housing is also of the same bolt pattern.
Kahn I think its mainly the tripods that have a different pattern, and apparently the ar5 is lumped into that category and maybe the jzx110 shifter I posted (we think).
I am not positive which ones have which pattern but if that diagram is right then for the ar5 and yours matches that, it should work cause that is what people bolt to the ar5.
Not 100% though so do some checking and more research. you might even be able to message one of those members on CL to ask for a measurement or details, just going off what I remember from all the ar5 swap threads.
I didn't see that 33252-22030 piece in the part number on that swap thread, but it looks like you might need that piece, it probably bolts onto the main shifter shaft in place of the lever that is there now, and then the ball mechanism just drops into that when you bolt it down. I have heard this style shifter has a good feel to it, it is one of the newer ones toyota made for the jzx110, so thought I would throw it out there.
The billet housings and lever would get the job done similarly, just depends what you want to do and if this one would fit or not.
I like how it has a factory style breather on the top of it also, you want a breather in that area to relieve some of the oil/pressure buildup on big pulls.
Based on what I've been reading this morning, I could either replace the piece on the main shaft with 33252-22030 or replace the piece inside the shift housing with 33250-24010/33250-22020. Both parts seem pretty hard to come by.
guess this is what it looks like, I would stick with the 33252-22030 from what I am seeing. do you have a picture of whats on the shifter shaft now?
Notice it has that flat piece on the bottom, that looks like it sits between those 2 pins on the side to keep the shifter centered, might vary from adapter piece to adapter piece, I would see how your current one looks first cause I am not that familiar with the r150 shifter setups to say. if it the same then use the one that will retain the same centering mechanism.
I think you have the right general idea though, but being the first it usually takes some guessing/experimenting.
