7MGE powered Toyotas like the Supra and the Cressida use a W series tranny. If you want to use a W56 tranny in your truck you will have to use a bellhousing from a Supra or a Cressida It is pretty much a bolt-in job, except that the clutch slave cylinder mounting face on the new bellhousing will be on the driver's side. The W56 is adequate for the 7M's power output, but the R series transmission is twice as strong, its just that there is no bellhousing that will both bolt up to a 7M motor and acommodate the short input shaft on the R150 transmission. The Supra turbo uses an R154 RWD transmission, so you would think you could use that bellhousing to mate an R150 truck transmission, but it's too deep. The R154 has an input shaft that is about an inch longer than the R's in the trucks. And you can't swap the input shafts because the gear sets dont match. Marlin Czajkowski of Marlin Crawler fame has told me that the believes an R150 out of a Tacoma would fit, although the output shaft on the Tacoma R150 is a quarter inch longer than the Supra R154 shaft. Nobody I know of has tested it yet. And of course you'd have to get an adapter to run a gear type transfer case behind the Tacoma transmission, just as you would with your current R150. The easiest route is to get a W56 tranny and a gear type transfer case. The only complication there might be some trimming of the trans tunnel shifter opening. -- Matt
