This is interesting...

 

its interesting, but if you get the remote housing from the soarer, then you can just put that on a solstice trans and not worry about the input shaft swap... just have to get the r154 front bearing retainer or use the solstice style clutches, alot easier than swapping inputs I think but I could be wrong.

 

Ali, I was under the impression that the Solstice/Sky AR5 did require modification to the very end of the input shaft. Is this incorrect? The front exterior guide plate around the input shaft (is that the "bearing retainer" you're referring to?) needs to be swapped as I recall.

This swap does look slightly more involved but I'm impressed there is yet another R-series family option on the table other than a 4WD transfer case only R150/R151 (or AR5).

What really impressed me was that there is another factory Toyota extension housing we haven't yet exhausted, since the 91-93 Soarer housing and internal shift arm are now truly discontinued even within Japan.

 

Yes indeed all you have to do is buy the jzx shifter kit and your finished!
And for the r154 guy's who are running one already but want a fresh trans you can use your all of your stuff you got already the 1jz clutch the flywheel the drive shaft all the same
Price point for a r155 is a lot cheaper then a ar5 you can jump on car-part.com and get one from a wrecked Tacoma 05-14 for $150-$350 easy with crazy low miles

 

If you brake it down
Trans$150-100+miles
$200-80+miles
$250-60+miles
$300-40+miles
$400+--10+miles
If you use your jz bell housing $free
If you use your rear tail shifter housing$free
No extended shifter? $300 from a jzx
Input shaft$180 new
Input shaft Bearings new $60-80
To switch out the input with bearings and all trans work If you do your own work $free
Good trans shop $100-250max
Gs400 3.26 rear differential $100-200 on car-part.com and I think that will be it

 

Oh and I forgot if you want to do the billet shift forks from marlin crawler
1-2 $129
3-4 $119

 

Yes input shaft on the AR5 is a hair longer, which you can easily shave down without tearing down the trans like one of our members here did and documented. I have also read that there is enough extra recess for the longer input shaft and that it doesn't even need to be shortened, and yes the front exterior guide plate is called the "bearing retainer". its a bolt off and bolt on affair.

the reason most people stay away from the truck transmissions is the 1st gear is geared very short to get the extra weight moving. You could aso use a R150 2wd transmission, from years 8x-95 (behind the 3vz) they had the short input shaft and wont mate up to a JZ without an extension or shaft swap, and from 96-04 (behind the 5vz) they had the longer one that is the right length to mate right up to a JZ motor.

the OP is referring to the R155 found behind 4 cylinder 05+ tacomas, which is the updated version of the same transmission but I had not idea what the input shaft length was on those as its mated to a new motor, but this thread helps answer that which is good info.

 

Could the r155 pair up with a 1uz just as easy?

 

this is awesome man what kind of power do you expect it to hold? why a 3.2 ring?

 

Yes its the same routine for the 1uz guys but you who'd need that adapter plate for the r154

 

Around 600-700whp is what my friend is going to run and I don't see why it who'd not hold more then a r154 remember guys the r155 don't have the thrust washer problems like the r154 and looking at the 155 gears they look more robust

 

3.26 rear to stretch out the smaller gears ratio set on the r155

 

There is more things involved with the ar5 for it to work and the price point as well you can buy 2# r155 trans for the same price as 1# ar5

 

Looking at the gear ratios, 1st, 2nd, 3rd and 5th are all more aggressive than with an R154. Overdrive takes a hit too-- more aggressive than both a W58 5th and R154 5th.

Not that I'm saying these are bad qualities. Aggressive ratios can be fun. Just worth noting for gearing preferences.

The 3.77 (TT Auto) is the ratio still seems like a good choice for the R155 too.

R154:
First Gear: 3.251:1
Second Gear: 1.955:1
Third Gear: 1.310:1
Fourth Gear: 1.00:1
Fifth Gear: 0.753:1

R155:
First Gear: 3.95:1
Second Gear: 2.06:1
Third Gear: 1.44:1
Fourth Gear: 1.00:1
Fifth Gear: 0.81:1
Reverse Gear: 4.22:1

 

yes like i stated you can run a 3.26 rear to stretch out the gears but a 3.77 will be a nice option if you can get one for a good price$
