I think the W56 would do just fine behind a stock 3.0 V-6. (Getting it to fit, would be another story.)

The W56 is used behind the same 2.7 4 cylinder that is in the TAcoma on overseas Hilux. The 2.7 has the same 150 h.p./180 ft/lbs of torque output as the 3.0 V-6.

Fact is, the W56 would probably survive just fine behind the 3.4 V-6 as well. It's a strong tranny, you should see the torque it withstands in some overseas diesel applications. And I believe the Supra used a simlier designed tranny.

I was thinking of doing a 3.4 swap myself someday. But one cheaper and far simplier alternative is to get a complete built motor from Enginebuilder on this board. A new virgin head built is about $650 to $700 (can't remember for sure) and a basic stock short block is about $600 or so. Not a bad price for a motor that probably makes as much power as an LCE built engine. You won't be running anywhere near as much power as a 3.4, but you dont' have to worry about motor mounts, trannys, ECUs or wiring. And you'll approach the power levels of the 3.0 V-6. I think that's the route I'll go, when mine blows up. Got a while to go, though, it's still runs super strong even with almost 200K on it. <img src="/forums/images/graemlins/kewl.gif" alt="" />
