V6 "How To"

[Node]

Ok Guys, Im going to need a little help with this one since I can be a bit forgetfull and there are a lot of subtle differences in the swaps. So, let me know what I forget and I will edit the post accordingly. I will be listing info for the SW20 chassis but information for AW11 swaps would be nice too.

This is a pictorial aid for anyone interested in swapping a Toyota 60* V6 into an SW20 MR2. I tried to take it step by step.

Still in the works but you guys may post replys.

Removal of the stock motor 3S or 5S. Keep the parts organized, you will be using many on the V6 motor.

Things to remember:
Cap off coolent hoses
Protect fuel lines from contaminants and dont loose the banjo bolts and crush washers.
DONT CUT your wire harness, if your using a stock ECU you will be grafting the old MR2 harness into your V6 harness.

Keep the stock starter relay, you may remove the fan control and the stock ECU

The following is exactly the same for 3s or 5s swaps.

When your engine arrives check it over for sludge. Keep in mind some of the V6'es have been in grandmas car and may not have seen much attention.



This motor is a 5VZ but the swap is nearly identical to all other swaps. Notice the complete lack of motor mount on the front of the engine.

This is the 3S flywheel sitting on the 5VZ crank. I suggest replacing the 5VZ flywheel with a 1MZ wheel rather than modifying the 3s wheel.

The 3S-GTE pully fits right onto the 5VZ crank, the 5S pully should too. Remember to RE-mark the 4cly crank pully, the timing marks are in a different location than on the v6

You can not use the 5VZ spacer plate because the starter is on the opposite side. You will need to "modify" the 3S or 5S plate.

1MZ flywheel with MR2 TURBO pressure plate and disk





Here you can see an issue with the axel from the turbo transmission and the 5VZ block. There is no mount location for the axel holder. You will need to make an adapter that will bolt into the motor mount location.

[Node]

Yes you CAN drop the motor and transaxel in from the top, by yourself I would say even the 4.0 v6 should fit through the top.

[Node]

This is an example of how to fabricate a motor mount to bolt into the radiator fan mount on the 5VZ block. The MZ has a mount here already so you guys wont need to fab one from scratch.

Here you can see a prototype adapter for the turbo axel. This should give you a good idea of how everything could bolt up without needing to machine the axel .



This is the coolant outlet on the 5VZ. Since its from a truck it faces the wrong way and needs to be cut and reshaped. I used an angle grinder, torch and bigass hammer. EDIT: the plastic 3VZ-FE coolant outlet bolts up and requires no moddification


Here is the Cummings turbo coolant F pipe that works perfectly as a coolant fill pipe and heater core hose.

Sorry these are blurry but it serves as a warning to everyone planning a swap. You should get your ECU, harness and, engine from the same year. Toyota was nice enough to move some pins around between 96 and 98 so I had to MAKE my own ECU connector with DB25 computer pins and hot glue. Can you say "GHETTO" I think I can

[Node]

You can swap all the mount plates from your 5s ECU or 3s to the OBDII ecu and it will mount in the stock location. I have an intercooler pipe running through there so I mounted it on the trunk floor.


Good luck.

Great write-up thanks for posting it!

Hey man , You should use Pinnancle or some sort of video editing software and add those pics along with some narration. Then everyone could download a video. This is what PJ and I used for our wedding invitations and our wedding thank you cards.

wow so how fast does it go now?
could u add a turbo to it too?

[Node]

Assuming that we actually have all the parts on hand, the install could take a single weekend. That doesn’t count all the hrs spent fabricating parts before the swap begins. I have yet to be able to prove that since every swap we have done required other custom work besides the basic swap. Things like intercooler pipes, E.M.S. Custom transmissions etc...

Turbo? Of course!

great write up and info...makes me think about a v6 now...
is the last pic of TRDNYCs car? both look like beasts. again, great job............................................... .................................................. ............................

YYYYYYEEEEEEEESSSSSSSSSSSS!!!!!!!!!!!!!!!!!!!!!!!! ! i would love to see that car one day in real life, like at a show or something. i would definatly bring a bib so that i won't drool all over the *******. That is some amazing work u got there. i am amazed at how clean it looks and at the amount of space left over. I wonder how much this swap would cost the average joe like me. With all the parts and labor. How much would you charge?

[Node]

Yes, that is a pic of TRDNY's car. I just wanted to show a pic with a turbo.

Let's not clutter up the sticky. Ill be happy to discuss what components cost etc via email or on the phone. Email me (persekjim at yahoo.com) or via AIM jimpersek
