You can't put the W56 behind a 3.0 because there is no bellhousing that has the 3.0 engine side bolt pattern and the smaller W series bolt pattern, and the W series trannies are WEAK compared to the R series ones. The best that you can do is get an R151F turbo tranny from an 86-87 22RTE truck and use the existing 3.0 bellhousing. That will allow you to have a lower first gear ratio (4.31 vs. 3.83) and also a geardrive 23 spline transfercase. This would be a bolt in application by the way. The only other way would be to swap in a 22RE/2RZ/3RZ engine. For the 22RE the W56 would be a bolt in swap. For the 2RZ/3RZ you could bolt up the W56 using the factory Tacoma bellhousing. For my truck I have a 98 Tacoma 2RZ with a Marlin 2/3RZ conversion bellhousing, R151F tranny, and dual 23 spline transfercases with 4.7 gears in the back case all sitting in the garage waiting to be swapped in.

I would use the r150 before the r151. The r151 has a 4:1 first (to make up for the power curve dip due to the turbo). I beleive that is too steep of a first for the v6

That may be true but it sure helps out on the crawl ratio when in 4-low especially if running a stock transfercase. On my truck when the R151F and dual ultimate crawler are installed will make up the difference in crawl ratio between 223:1(3.83x2.28x4.7x5.29) and the 244:1 (4.31x2.28x4.7x5.29).

If you're just about crawl ratio, why don't you put in a third case?
I'm at 200:1 (same as above but 4.88's in the diffs) and it's lower than you really need
223:1 is pretty ridiculous,
244:1 is ludicrous speed!
I would think the low first would be nice if you had dual stock cases
(4.13x2.28x2.28x5.29) = 114

I do have a third case, but I don't want to have to buy another dual case adapter and convert it to topshift (its a forward shift) to stack the third case, and I already bought the 4.7 gearset. Maybe a good idea to just sell the gearset and buy the adapter and convert instead. (4.31x2.28.2.28.2.28x5.29=270:1!!!)
