: Replacing 3.0 with 3.4

I want to replace my 3.0L V6 with a 3.4L V6 from a Tacoma (and eventually supercharge it ;) ). Correct me if I'm wrong:

My 3.0 V6 bellhousing (R150F) will bolt up to the 3.4L.
If I get the entire 3.4 wiring harness; the wiring should be manageable.
The intake and exhaust are opposite of mine and must be rerouted.
Since the replacement engine is newer, the smog czars will leave me alone. (I'm in CA)


Here's what I don't know:

Will the 3.4 bolt to the 3.0 motor mounts? Keep in mind that the T100s were available with both motors at one time, so there must be some simularity there.
Must the oil pan and pick-up tube be changed to work with a stock torsion bar IFS setup?
Can I keep the stock 3.0 fuel pump, etc? Or must I upgrade?
Will the damn thing fit under the hoodline?


I appreciate any help you can provide.

Go right ahead buddy. I read every thread with the numbers "3.4" and the above questions were NOT addressed.

All found by using the search button, I was going to do the swap and buy a TRD supercharger. But just decided to go with a cam, headers and an intake.

I don't read well? How about answering the questions entitled "Here's what I don't know" instead of the ones I already have answers to. You won't find those using search thus the reason I posted here.

same engine at the same time in a T100? 93 and 94 had the 3.0. 95-up had the 3.4.

What I meant was both the 3-liter and the 3.4 were used in the same chassis truck.

Where are you getting this information rockpimp? I have read every discussion on POR about the swap and never saw my questions addressed. Have you done the swap? I'd like to see it.

I want to limit the number of surprises I encounter with such an engine swap.

You're right, he hasn't done the swap. What he HAS done is spread mis-information. I was able to get in touch with someone who has done a 3.4L conversion. According to him you do have the change the oil pan setup and it will NOT fit under the hoodline by just over 2."

I wasn't looking for uneducated guesses or "use the search" for responses.

That's helpful, thanks. I assume the T100 has the sump at the rear?

Or are you one of those guys who asks questions, then pays someone to work on there truck?

Come to think of it, I did let Toyota work on my truck for free when the headgasket blew.

Do you have a truck?

No. Why drive a truck when you can drive a Geo Metro? :rolleyes:

Ever been wheeling?

Yes. I drive to band camp on heavily graveled roads.

Do you know that there is no need for BIG HP when you have a marlin crawler?

I want big power because it's fun and I can afford it.

I'd like to see some pics of what you drive!

It looks a little different now. The stock 1.3L 3 cyl is mated to an NV4500, Atlas II, un-cut D60s, 44" Boggers, blah blah blah.

Thanks for completely hosing this thread.

I also looked into doing this and will eventually or do the 7MGTE. I'm not 100% sure, but I believe( closely looked at the two side by side) the 3VZE and 5VZFE oil pans will interchange. So you should be able to use your pan/ pick up and dipstick. I do know that if you did change to a T100 pan you need to change the dipstick and tube also , on the older 5vz's there is a plug and this is easy. On the newer ( atleast the double cabs) the front plug is not there, meaning you have to trim the dipstick. If you already have the 3VZE this would be an easy swap. Also the stock 3VZE pump puts out about 20 gal/hr or around 220hp. If you supercharge it you will need ethier a better intank pump or what I did and ad another pump in line.

If you don't want to be helpful, then how about don't say anything at all? :mad:

FWIW, a stock 4.3 and 3.4L have just about the same power. The 4.3 just makes it at a little lower RPM. The 3.4L will be nearly a bolt-in swap compared to a 4.3L swap.

My 3.0 V6 bellhousing (R150F) will bolt up to the 3.4L.

Yep.

If I get the entire 3.4 wiring harness; the wiring should be manageable.

Yep, probably. Make sure the motor you get is for a 5-speed.

The intake and exhaust are opposite of mine and must be rerouted.

And the fuel lines.

Since the replacement engine is newer, the smog czars will leave me alone. (I'm in CA)

Yes, but you will still have to take it to the ref the first time...



Will the 3.4 bolt to the 3.0 motor mounts? Keep in mind that the T100s were available with both motors at one time, so there must be some simularity there.

Yes, from my 3.4L T100 and other 3.0's I've seen, the mounts look identical.

Must the oil pan and pick-up tube be changed to work with a stock torsion bar IFS setup?

Yes, if the 3.4 is from a Taco or 4runner, no if its from a T100 (T100 uses same t-bar IFS).

Can I keep the stock 3.0 fuel pump, etc? Or must I upgrade?

I would imagine so for the stock 3.4, not sure w/ the SC.

Will the damn thing fit under the hoodline?

I don't see why not, but apparently somebody said otherwise...? I guess you'll have to look into it more. I can take a measurement from crank to top of motor for you if you email me after Tues (I'm 1500 miles away right now).

Hi Eric, thanks for your reply. I have recently learned that the 3.0 oil pan and pick-up will bolt onto the 3.4. That's very good news. I can manage the wiring and I now believe the 3.4 does use the same motor mounts as the 3.0. I am a little concerned about whether or not the exhaust cross-over pipe will fit between the motor and the firewall. If not, headers will be my only option. I can now confirm that the 3.4 will not fit under the hood of an '89-95 pickup by 2". That means body lift or hood scoop.

as for the motor fitting under the hood, i think an L-88 hood would like nice on a toy!! :eek:

As for the fuel system for the 3.4, you said you wanted to supercharge it.

The Taco guys have quite a bit of experience with fuel problems on a s/c 3.4. You will have pinging problems even with the 3.4 fuel system after s/c'ing. So head over to the www.tacomaterritory.com msg board for the fuel info. You will have to ask, the searchable database is not as good as PBB.

Also check www.gadgetonline.com for more fuel and ecm info on the 3.4.

I don't have answers to any of your questions. But if you do the swap, please post the info, don't just email to some other guy, SHARE!.

Actually I had that low rpm/ hi gear ping. I Called TRD and they gave me 3 fixes to try and solve the ping! One use 60-70% water to antifreeze instead of 50-50 if you climate will take that, sec Install 2 heat range lower spark plugs they suggested IK-22 Denso plugs and 3rd use a lower degree thermostat 160. I did all three changes and I don't any ping. Far as instruction for install changes from trk to trk.. and have info to share... by emailing me i will give you my number and you can drop me a call and i will be more that happy to work out details for your application based on my reserch and I can be specific. I wished I had this info before i got started...

Have a good one and I dont mind helping others.

This was a little Problem... I used the 22rte senders for the oil pressure, and the temp gauge i used the 3.4L... the tach required a modification... I used the 3.4 p/s pump, Alt, and A/c compressor. It passed our emmission laws on the machine i call it without a problem. I also have OBDII compliant hookup for the scanner.

If you are using an 99-02 with an coded key i can tell you how to disable it where you dont have to have the coded key where it can start.

You sound like a guru. You need to spend more time around this board.

That 3.4 is a sweet motor. I bet it kicks ass in that truck.

If you put the 3.0 motor mounts on the 3.4, the motor is a direct bolt in. We just did this last Saturday.


Will the damn thing fit under the hoodline?

If you put the 3.0 motor mounts on the 3.4, NO, the upper intake hits the hood, but this can be worked around by either cutting a hole, doing a hood scoop of some sort or welding in a "bump" like an Eagle Talon has
