Dude Man

So I was planning on doing the swap back in April, when I first posted this thread, but decided to hold off until after my trip to Whipsaw Trail.



Whipsaw was amazing but now its time to get this 3.4 in..

The donor, 1995.5 Tacoma.




Pulled the 3.0 a few weeks ago.






And dropped the 3.4 in last weekend.




Didn't take many pictures while it was on the engine stand but I also installed a new timing belt, water pump, pulleys, valve cover gaskets, intake gaskets, etc.

ADD system and rear heater are also being removed.

I have a few simple questions to start with.

1) The Tacoma has no EGR system or an EVAP box. It just has an old style charcoal canister with the addition of a single VSV.

So basically all I have to do as far as EVAP goes is hook up this VSV between the intake manifold and charcoal canister, correct?




2) Most of the info I've found says that you can use the 3.4 power steering pump with the 3.0 lines as long as you use the 3.0 bolt. But after looking at the two side by side it doesn't look like there's anyway the 3.0 bolt will fit. Am I missing something?




3) There's barely ever any mention of the transmission wiring/connectors.. I assume for a manual the only sensors would be for speed and 4WD, are the connectors the same? Also, any tips on routing this part of the harness past the exhaust and steering shaft?




I'm sure more will come. Any comments or advice are appreciated.

Cheers!

swap over all the emissions components including o2 sensors.
The power steering fitting youre holding still has the bolt stuck in it. You need to remove the bolt from the "nut" and it will bolt up to the new pump.
I usually run the wires for the trans down and along the torsion bar then cross it over to transmission running under the heatshield for the exhaust.

What Vital said..............except I have no torsion bars anymore so zip ties are my friend as tight to the trans as possible and away from the exhaust. Not much to work with but doable.

Interesting.....I have never seen that EVAP setup before on any 96+ Tacoma or Runner.

What's going on with that chopped Tacoma?

Dude Man

Thanks man. I'll try to loosen that nut from the power steering bolt, its really on there!

Yeah the whole thing had me a bit confused at first since most swaps I've seen involve that evap/squid box.. I'm really liking it though, no EGR system and only one vsv for evap. Should be a very simple, clean engine bay when all is said and done.

Its technically a 1995.5 Tacoma, could be why.

Pictures are out of order. I cut the back end of the Taco off last year and used it for the pick up conversion.. now I'm swapping the engine over so I can get rid of it.

Its been too rainy and cold to do anything lately. I'd like to push the Runner into the garage so I can work on it regardless of weather but I need a hand.

Did some work on the wiring this week which raises another question. Since I'm removing the ADD system do I really need to hook up any of the 4wd wiring?

Dude Man

Finally got it fired up on Sunday!




There's a few vacuum lines on the back of the intake manifold that were knocked off while the engine was being dropped in.. Specifically the 3 ports shown below.

I'm pretty sure there was a T fitting between the three but I can't remember.

Does anyone know how these hook up? I would really appreciate it!

Dude Man

Well I called in sick today and worked on the rig for 12 straight hours.. just took it for the first drive but there's some issues.

- I have to start it twice for some reason. The first time it always stalls.

- WOT just makes it run like crap, it accelerates faster at 80-90% throttle.

- Clutch pedal feels very soft.. Could just be because I've been driving a Mustang with a very stiff pedal, not used to it.

- Power steering pump has a loud whine. Kinda remember this from when I bought the Taco.

- Throttle response doesn't seem right. I think this is related to the first two problems listed.

I haven't been able to find a resistor yet so tach isn't working, interior is still mostly in pieces and the tranny harness isn't plugged in except for the o2 sensors.

Though with all that said I am so glad to have my rig back. It will feel great to drive it to work tomorrow even if its running like chit. I'll scan it and see what codes are stored.

Any suggestions on my issues would be appreciated.

those need to be tee'd together. That hose comes up from the fuel pressure regulator. Connect the three for now, that should solve some of the fuel deprevation.

Dude Man

Actually I found some old pics from when it was on the stand, the two metal ports tee off to the ADD system and the VSV was just missing its cap thing.

Barely got it started this morning but I managed to limp it to work. Brought it in the shop at the end of the day, hooked up the OBDII port and found only one code, P0100 - MAF circuit.

Was easy to diagnose at that point.. turns out I forgot to hook up the power wire to the MAF sensor.

Got that done, cleared the codes, fired it up and its running great now.

So now that the engine isn't in limp mode I got my first real drive with the 3.4.. It's surprising how much of a difference there is, definitely exceeded my expectations. I'm still curious to see how it does fully loaded on long highway trips as that's where the 3.0 was always at its worst.

I was so pressed for time I basically just cut the exhaust pipe on the Taco right before the muffler and threw it under my truck. So its just the crossover, cat and straight pipe to about the rear axle.. Loud as hell but it actually sounds ok for what it is.

Could I use a 1/8 watt resistor for the tach mod? I kinda doubt it since I always see guys using 1/4 or 1/2.
