My AR-5 Recipe
Here is my recipe for a buttery smooth shifting AR-5 transmission. I know there is an AR-5 progress thread with allot of great information already. I just wanted a more clear cut layout. In my personal opinion this is the best way to achieve this swap with the least amount of parts to source. This was done on my '01 MSM IS300 with 2jzge VVTI.
*One thing I want to clear up because I have seen it said more than once in different places.*
**Flywheel does not matter** Some people have said the 2jz flywheel is too big for a 1jz bellhouse it is NOT. Think about it, the block bolt pattern is the same and the starter mounts the same no matter the bellhouse so how is the 2j flywheel to big? IT IS NOT TO BIG either flywheel works. Sorry had to get that out.
Parts and steps needed. (not including auto to manual swap parts)
1. '06 Pontiac Solstice AR-5 Transmission
2. Bellhouseing for 1jz to R154
3. Shifter housing for jzx100
4. Shifter - Short throw stock shifter (w55) could use a stock jzx100 shifter. I personally used a Ralco RZ short shifter for the IS300. (I had to make the bushing that goes into the shifter housing a tad bit smaller, makes for a nice tight shift.
5. 2JZ W58 style flywheel. I used a lightweight flywheel.
6. ARP flywheel bolts(recommended)
7. W58 style pressure plate. I used a stiffer than stock pressure plate.
8. Pressure plate bolts. *I highly recommend getting grade 8 bolts that match the factory bolts. The reason I say this is i had some serious frustration when a new factory Toyota bolt broke in my new flywheel. I ordered a set of new pressure plate bolts from Toyota and one broke trying to torque to factory specs. The bolt ended up having an air bubble right at the head of the bolt. And they are only grade 5 so I matched them to some grade 8 bolts. Just what I did personally.
9. Custom clutch disk from ACT
10. *GM Part* Pontiac Solstice Slave cylinder. Comes as an assembly with the throw out bearing. From what I can find the factory doesn't sell just the bearing. The slave cylinder needs to be mounted upside down.
11. *GM part * Pontiac Solstice clutch line. Ok so I had my local hydraulic hose shop take the end that fits the slave cylinder and take the flexible rubber hose off and solder a 10x1.0mm female fitting on. I made custom plates to cover where the external slave mounted and customs side cover plate. Take and carefully bend the hard line so it comes out and up right against the bell housing towards the top of the trans. Then a standard stainless steel braided clutch line will connect to it.
12. Get a clutch master cylinder for a 1986 Toyota land cruiser. Now take the clevis off of the threaded rod and cut 5/8th of an inch off. This allows for proper clutch adjustment. This is no option has to be done the factory master can't be used. (use vacuum to bleed the line as there is no bleeder screw in it.)
13. AR-5 Transmission output adapter from Drift Motion part # DM3119 call and talk to Aaron and let him know that you are using the jzx100 shifter housing (the adapter is milled down some for clearance, I worked with Aaron on this)
14. Custom drive shaft for Toyota rear end to the Dana Spicer 119 adapter flange on the DM3119 adapter. I used a local company and wouldn't use them again if you're in GA pm me and I'll tell you who they are. I recommend getting drift motion to make you one.
15. Finally the transmission mount. I used a new Lexus w55 trans mount. You turn it around backwards add 5/8" to the rear end of the mount and drill the extra mount hole on both sides you need. I used the aluminum mount that bolts to the transmission when used in the solstice as a template for laying out the holes. (the opposite side of the little metal piece on top.) This fits the transmission perfectly to the car. No shims, washers or anything of any kind.
16. I almost forgot you need the BMW pilot bearing.
Now you have one of the nicest tightest transmissions I've driven.
A few notes I have are...Take the exhaust manifold off the engine and separated from the rest of the exhaust. I did not have to loosen the motor mounts or do any beating to my tunnel this transmission fits perfect. My drive live angle is non existent. Smooth as butter. Also note I did this on jack stands wasn't bad at all. I love the internal slave it is so quiet and responsive. Again everything above is my own personal opinion and I support everyone and their own way.
I do believe I am the first and only IS running this exact setup. At least for now. . .
Also sorry for the lack of pictures I've lost t all but the few I took on my phone.
