Topic: 5VZ-FE 3.4L into a 1985 xtra cab

[Mountain Yoat]

 Facts needed?    I'm installing a 1998 Taco 3.4 into a 1985 Xtra cab frame.    I need to know if there is a toyota bellhousing with Clutch slave on RH side that will bolt up to the 3.4L aswellas a gear driven T-CASE at the rear.   I am reversing exhaust crossover to run down left side to avoid having to move fuel tank to left side. Up for debate!

A couple of years ago I found some info on 4x4wire.com about a guy doing a 3.4L swap into a 90's 4runner

The short answer is yes... Sort of...

You'll want to run either an R150 or 151 tranny.  Both of them, in the pre-taco form factor, have right side slaves.  The 150's in the Taco's have left side slaves - but you cannot use this bellhousing with an older 150 or a 151, as the input shaft on the Taco 150's is longer.

So find yourself a 150 out of a Taco/gen3 4Runner.  To bolt it up to the gear drive t-case, you'll need Marlin's 150->tcase adapter...

lets see some pictures of the setup!  Are you re-engineering the crossover pipe for the exhaust, or bringing it down and crossing it to the other side of the truck after the trans/tcase setup?

I've got the lines drawn, I'm going to hack the original crossover, grind of the welds and for the most part reverse the arrangement to run down the right (Drivers side) to avoid a number of nasties like the front drive line, fuel tank placement, weight distribution.

As fer the tranny I have the 3.0 bell with left side slave but the tranny is a 1998 taco rightside slave. The bell bolts up but the engine mounted end of the 3.0 bell is 1 3/32" shorter than the 3.4L so I guess I will have to cut out a matching ring to weld up to the 3.0 bell unless someone knows a particular year of T100-Tacoma which has the longer bell housing and a left sided slave?

When you say left-side, are you talking left side of the tranny as facing the front of the engine - I.E. driver's side?  Cause I think we're using "left" in two different ways. 

You're looking for a pass-side slave mount bellhousing to mount to an 95+ r150 tranny... correct?

I think you have two options - find an older tranny... or make a spacer.  I'd personally recommend finding a 151 instead.  It will bolt right up to your exising pass-side slave bellhousing and directly to a gear drive tcase equipped with 23 spline input.

It won't be cheap, but likely cheaper than having an adapter ring custom machined or custom bellhousing made...

Sorry, your right I meant the Passenger side, the slave resides on the passenger side of the tranny. (Right Side of truck)
and yes that is to mount to a 95+ r150.
As for the 151 is the turbo diesel tranny a 151?

I'll try and get a couple picks of this projects beginning on here soon.

No idea what's in the turbo diesel, so I can't help there.

But you'll need an older R150 (88-95) or an R151 to use with that Pass-side mount slave bellhousing...  The 95+ 150's wiith the longer input shaft will either need a new input shaft or a custom machined spacer...

Or... what I'd do...  Route the exhaust down the pass side like the stock manifolds do, with a cross over under the tranny infront of the Tcase back to the driver's side.  Then use your 95+ tranny/bellhousing and call it good.

I'd like to kept the 98 transmission (It's a milage thing) If I could use the Toyota Turbo tranny from behind that diesel and a 3.0 bell the tranny will need a rebuild vs custom spacer between bell and 3.4L block.  I kinda like the idea of pushing the Tranny/TC weight back another inch which will also result in a required extension of the front driveline. (Weight distribution, equal length drivelines?)
        Routing of exhaust is still up fer debate.
Whether it crosses over by the TC or above the bell it still has to cross over and eventually run down Drivers side?

I am preparing for a similar swap.  I managed to find an R151, which mates nicely to the 3.0 R150 bell, which mates nicely to the 3.4 with a 3.0 throwout bearing.  Otherwise, I would have chosen the R150 behind the 3.4 and used a Marlin adapter plate to keep things simple (and move the motor forward a tad, which must be done to clear the firewall and work with the radiator - and as a side benefit *should* provide crossover room behind the heads).

Parenthetically, you have to move the whole drivetrain forward about 3" on the 22RE trucks with this conversion.  They look the same as the V6 trucks, but they ain't.  Even Mike Caskey was surprised when we measured things up from various start points.  Just thought I would make your day with that... 

I am torn on exhaust as you are.  I am considering what you suggested, grind the welds off the stock 3.4 crossover and reverse it.  Mike Caskey warned me that fitting the motor is the highest priority, and that may or may not leave adequate room for the stock crossover, so my second option is as BKG describes:  a below-the-drivetrain crossover.  Not real thrilled at that but should create no clearance problems if done right.

Mike Caskey crosses over behind the tcase.  I don't want to go back that far really.  I snagged the cat & front exhaust off the donor to make things easier too.  I'd love to pay Mike to do the work, frankly, but he doesn't think he could get it done before Cruise Moab.    Yeah, like I could, on evenings and weekends... HAH!

[edit] had another thought... you could go with Downey headers too, and run duals to the cat.  Just a thought.  Crossover issue remains.  Well, you could just use the stock headers too.  Nevermind.

So the R151 does bolt up at both ends   I checked out a tranny from behind a Turbo Diesel Toy, 1987 I think,   That tranny definitely does not bolt up to the 3.0 or 3.4 bellhousing though because I tried my template against front end of it and the trannies mating surface was smaller than my 3.0/3.4 template. Of course that bell is nfg to me, it's off a 4cyl diesel.
Does anyone know if this tranny from behind the diesel would be a R151 or a W56 HD
 Is a R150 from a 95+ stronger than the R151 experienced tranny rebuilders please
If so I will bite the bullet and cut 1 1/16 of an inch off the engine end of the 3.4 bell and weld it to the 3.0 bell to compensate for the length difference,    and buy the adapter to mate the Gear drive TC adapter TC. 
If the R151 is as strong I would need to find me one as this is obviously the easiest and posibly cheapest (less adapter plates) way to go
