Gen 3 Tacoma Chevy 350 Swap

Oh to the OBD2 question. OEM engine harness is removed. There are no original working electronics accept for the interior amenities. I separated the power for ignition fuel and fans so I can run the truck with all power off to the truck and then I have a master switch to turn on the power to the truck itself. This can only be done in a non DEQ area. I will not live in a place that requires DEQ. Im sure I will be hated by all electric car owners.

 

Dude you are my freaking hero!

 

Thank you. I was just in contact with a guy I know that does really good drone videos so hopefully i can get you guys some footage of it driving out in the Oregon gorge area.

 

Would love to see that. If you ever get the bugs worked out enough and decide to visit the coast hit me up! Got some cool spots to test that beast out! Keep up the good work

 

Oh for sure. No bugs left, fingers crossed. When I head twords the coast I'll hit you up for sure. I have a lot of spots I wanna hit up. Thanks for the invite!

 

Anytime brother

 

I put a Sequoia booster and MC in my 2nd Gen TRD Sport. It made a HUGE difference in initial brake responsiveness. No modification needed, just some short custom brake lines and a longer plunger rod on the brake pedal.

I have no idea if that’s applicable or useful for you or a 3rd gen, but can point you toward more details if so

 

Point me at some more info on that and ill definitely look into it. I was also told to use a larger master cylinder made by chevy however I would like to research multiple options. I did get the breaks working pretty well though as I stated earlier they are still a little spongy. Ill take any info you got!

 

If you’re going to SAS it with a Dana 60 you absolutely want to upgrade the brakes.

It looks like the 07+Tundra/ 08+Sequoia brake booster will also fit 3rd Gen Tacoma TRD Sports. That’s the booster you want; it has a large dual diaphragm, which you need to push fluid through the larger port on a bigger master cylinder.

You will also need this extender (or one with the same dimensions) to extend the plunger rod on the booster that connects to your brake pedal: https://ebay.us/m/JK95Vi

I believe the port for a Tundra/Sequoia master cylinder is 24mm, which is a big step up from the (14mm?) Tacoma MC. You will need these brake line adapters to connect the Tundra MC to your existing hard lines. https://autobrakesolutions.com/prod...-line-kit-12mm?rq=yr_2016~mk_toyota~md_tacoma

And that’s it! That and some brake fluid is all you need to make the swap.

As an alternative to the Tundra/Sequoia master cylinder, you can buy an adapter to mount an even larger 1 ton GM master cylinder on the Tundra/Sequoia booster. (Maybe that’s the GM master cylinder you already have?) https://trailtoys.net/products/one-ton-master-cylinder-upgrade

I don’t know as much about that setup; I’m personally running a Sequoia MC because I’m IFS.

If you decide to buy a used booster from a salvage yard, buy from a yard where you can pick it up yourself. I ordered three different boosters by mail and they all arrived broken from shipping.

 

Awesome! Thank you for that. This is what im going to do. Your amazing!

 

The bigger booster and MC are going to protrude farther from your firewall. If you have a bigger fuse box or if any components for the engine swap take up more space there it might involve a little rearranging. If it’s clear, it will probably seem like the bigger booster is not going to fit against the firewall, but if you angle it right it should go in.

 

So putting a chevy 350 in this engine bay has freed up over half of the space. I have so much room in there I spent most of my time sitting in the engine bay doing the final button up work!!!!

 

That is awesome! I had a ‘67 C10. I loved how much room there was to work in the engine bay.

 

If you end up needing to do your front brakes before you do your SAS, you can swap in larger rotors and calipers meant for a 5th gen 4runner or LX460. They bolt right up. The larger mass keeps them from overheating as quickly so the rotors won’t warp as fast and you won’t get as much brake fade. And they look nice behind the wheels. You will want to pick up the larger dust shields too.

 

Ok thank you! Looking into it now.

 

Cool thread! Back in 70's, there was a guy here in the Atlanta area that put a small block 350 in a VW van! Those were the days!

 

I did this swap already. I am very happy with it.


I wouldn't recommend the Raybestos S-groove rotors though.

I used this 2nd gen post as reference.

The front brakes on the 2nd gen are the same as the 3rd gen. So everything in the write up applies.

 

Used to see a guy growing up, he had a beetle with a v8 in the front, driver sat in the backseat

 

Hey- the next time when you and I both need to change the spark plugs, I’ll trade ya! Dang, I miss the days when I could even see them on the engine!
