NZ 3S-GE to 3VZ-FE help

[Denz]

Ever since I bought the car ive been thinking about doing a V6 swap.
Ive just done a lot of reading and I think I have a clear understanding about whats required of me. Please double check? Im hoping to do this within the next year.

I can get a wrecked Camry, Windom or Sceptor with a 3VZ-FE in it for between $120-$700USD So that would include everything. BUT In NZ they only came with Auto ECU's is there a way to overcome this? Fool it into thinking its in drive?

Flywheel - Slightly redrilled 3S-GE
Gearbox - Std S54 (Whats MPG like at 3500 rpm?)
Fuel Pump - Std 3S-GE OR Pump from whole care
Radiator - Std 3S-GE

Questions.
Is there a way to use the Auto ECU?
Is there any plans online for an engine mount, the 4V6 Mounts look almost as much as the engine will be.
Is there a wiring diagram for the 3VZ-FE and 3S-GE body?
Is there anything I have not thought about?

I really want to be able to use the STD Gearbox because a turbo one would be more than a whole wrecked car and my cluster I believe doesnt get the RPM through an electrical signal.(its an 89-91 build year SW20)
The engine will have any appropriate seals/ cambelt done depending on the milage.

1a. you can do the resistor trick but you need to find the values in the diagnostic book (3vz)
1b. you can buy a M/T ecu from the US and rewire the harness
2. build your own by hacking away some cylindircal motor mount.
3. your on your own on this, find a 3sge diagram and record all the pins
4. water lines, exhaust setup, tachometer

Just the fact that it's an AT ecu isn't necessarily a problem. It seems like only certain toyota AT ecu's have problems being run in an MT configuration. Here's a list of AT ecu's that I have used with manual transmissions:

-4age 20v blacktop jdm
-4age 20v silvertop jdm
-beams 3sge jdm
-caldina gen4 3sgte jdm
-1zzfe usdm
-1jzgte jdm

One difference that I've noticed is that I don't think these ecu's are connected directly to transmission solenoids whereas the 1mzfes are for sure.

Thanks alot
I'll look into USA ECU's
I saw on the Tech Info pictorial for a 5VZ-FE they used a triangular piece of steel with another smaller piece of steal sticking out for the origional MR2 motor mount, I was just wondering if the diagram for the 3VZ-FE equivilant was avaliable.
Bugger, i'll try someone in nz who has done the swap, ive seen a fiew of them. Altho it cant be that hard.

I was under the impression that the water lines for the 3VZ-FE lined up?
I read that the Tach should work however it would be getting a 6pulse signal rather than a 4pulse and read a bit high, however as id have a camry clusted I could just get the circuit out of that?
Sorry, its my speedo that is read by cable
Im not to far away from an exhaust shop, i'll try drive it/ tow it there.

Thanks, im not much of an ECU person but I know you can normaly trick most electronics.

That's the thing. There isn't any tricking involved. These AT ecu's just plug in in place of the MT ecu and run like normal. You do absolutely nothing.

Oh wow
That would make a lot easier, the other option was to measure the signal output from the gearbox when you put it into drive and copy that.
Seeing as your the harness king it seems. Can you imagine its amazingly difficult on the wiring front. Myself and friends helping are quite electronicaly savy, I assume its about as easy as just matching the pins?

This is an interesting read
3VZ-FE engine manual transmission with automatic ECU? - Camry Forums - Toyota Camry Enthusiast Forum
Provides a bit on insight on what you need to do. Along with this sites stickies.

I knew of an old camery with a 3vzfe you could of had for 200 running but I think they drained the oil then forgot about it and came back to it a few months later and drove it across town until it had rod knock. Not worth anything now.

The only thing I would be worried about is getting a cert for the car, could be no problem or could be a big issue, the guy in pukekohe is an a$$hole and a F**@#$%^@#*$^&*)*%@#& douchebag who takes pride in failing cars on things like paint flakes. He hammered a screwdriver through a beautifully restored 50's ford (not my thing but respect to the guy that fixed it) just to prove that he could hammer a screwdriver through the floor therefore it was a dangerous car. Sh**storm insued he was stood down for a few days, car was passed and he came back to fail more people, I have had many arguements with him and he is just pigheaded, never even worked on a car just as an inspector. Rant completed I don't know the certifier in hamilton, I would look him up and pull some info from him on what you need to do assuming you want to keep it legal of course.

BTW: I hope you have a good multimeter Your going to need it.

Thanks a lot, if I do need to fool it a constant 5V should be easy as pie. (One guy said lots of things needed to be done but at the end it said only a 5V to the speed sensor)
The ONLY thing I need a cert on is the fact that it is now a 6CYL not 4 and the Displacment is more. There will be nothing structural so it should be pretty easy. I hope... I will look him up.

I wonder how much you would be willing to help and how much it would cost for your input :P Mainly getting your dads(i think its your dads) machine shop to do an engine mount.

PS we need to meet up

[328FTW]

Yeah we do need to meet up. I always seem to be busy when I remember to fire you off a PM. If you measure up the mount you need cut out (I assume you will make it out of plate steel) and draw a template I can make it and get it to you, I have 6mm plate or 3mm, that is what I use for roll cages so it's what I have laying around. I can't remember the rules on welding things if you need a ticket, I can weld good but don't have a welding ticket. You would have to fill me in on how it needs to be made more specifically anyway, I can't make something important based on it has to "about this shape"

As far as a wiring diagram is concerned, there is a full DIY guide up on the twobrutal forums for an N/A-> V6 swap. I don't know if that's been addressed here previously or not, but that should pretty much take care of the wiring for you.
