AkumaNoZeta Posted June 11, 2013 Share Posted June 11, 2013 I'm building an 88 7MGE-T and all I could afford right now is a W58 transmission, for an early 260Z. I plan to upgrade to a R154 after the car is "finished" and before I try tuning for higher boost. My question is on the shifter placement though, does anyone know it the two transmissions are the same in that aspect? Quote Link to comment Share on other sites More sharing options...
ShaggyZ Posted June 11, 2013 Share Posted June 11, 2013 (edited) Depends which transmissions you get. Most of the R154's you find are "shorter," coming from the MKIII Supra, but there is another version about 1.5" longer, IIRC, and then another that's another 5"(?) longer. Most of the W58's I've seen are as long as the long R154 since they come out of the SC300/Soarer or non-turbo Supra. Regardless of what you do, I think you don't need to worry much about that difference. It has a negligible impact on the work required, especially if you have the motor set way back.

AkumaNoZeta Posted June 11, 2013 Author Share Posted June 11, 2013 I just don't want it to be off so much that I have to modify the center console. I want the interior to look completely stock. Quote Link to comment Share on other sites More sharing options...
piston Posted June 11, 2013 Share Posted June 11, 2013 I haven't actually compared the two yet. however you can always swap the top shifter assembly from the original w58 to the r154 when upgrading and it should fit. Someone correct me if I'm wrong. Quote Link to comment Share on other sites More sharing options...
seattlejester Posted June 20, 2013 Share Posted June 20, 2013 (edited) It looks like the w58 shifter assembly cover is thinner than the R154 one, which makes me think they are not interchangeable. The R154 with a 7mgte backed up to the firewall (leaving the stock hood latch mechanism) requires you to cut the transmission tunnel 2 inches forward and even with that a stock shifter might be out of the question (1, 3, and 5th, would be in your heater control). The w58 has the shifter located what I would guess is another inch or so back, so I would think using the stock center console is still going to be very difficult. The parts for extending the shifter cover and mechanism has skyrocketed, the toyota OEM parts for the two pieces needed to move the R154 back is roughly 200, there also is a service online that will extend both to your desired length and that costs approximately 250. I plan on extending the shifter itself back. Edited June 20, 2013 by seattlejester Quote Link to comment Share on other sites More sharing options...
