Rusty Red

[SByota]

^^ There is a guy with one of these swaps done and claims he has the butterfly valve controlled electronically like the VVTi does from the factory. He uses a Nitrous trigger and sets the rpm parameters. The theory is that the vacuum keeps the butterfly in long runner mode through out the rpm band. Great for low and mid range, but not so good for top end power or gas mileage on the hwy. Mine has been working well with just the vacuum hooked up, RCF Throttle Body, 270cc inj, Thorley headers and Y pipe with no cats. But I'm also only getting 13 ish per gallon average. I also have a URD MAF calibrator that I need to experiment with some more.

Looks like this may be an easy way to operate the vacuum switch that controls the runner length butterfly’s.

Ordered a bunch of Toyota/Denso stuff from Dubai https://partsouq.com/ they are popular with the Land Cruiser crowd for inexpensive factory parts. Parts arrived 7 days after my order. Looks to be all legit Toyota/Denso stuff. Even with $25 in shipping, it was still 40% cheaper. I will definitely order from them again if I need factory parts.

Cool, Im gonna look into that switch. Partsouq is pretty good. They had an order shipped to me in 3 days.

Still plugging away. Acquired $40 worth of vintage HF goodness. Motor is 90% ready to come out. Intake valves look great and no surprises on the tone end of the motor. Note to anyone pulling a Tundra V8. Pulling the intake will make the top two bell housing bolts WAY easier. We live and learn right. Parts are rolling in and so ready to get this rusty old truck out of my garage.

Check the starter solenoid connector on the harness while you have the intake off. They get baked and the tabs break off. You can get replacements from ballenger motorsports for like $5. Better to replace it now than have it pop off later.

Also check to see if the knock sensor connectors and wiring are good.

This is less than fun. To Toyota’s credit, lots of the wires are the same color/function between the Tacoma and Tundra.

To be completely honest, this is a huge reason I went GM instead of Toyota. Aside from cheaper buy in cost, I knew I wanted a v8 swap, and swapping any LS into the s10 chassis is nearly plug and play, especially with prebuilt wiring harnesses. Vaya con dios, mi amigo. I am not jealous of all of that.

I get it. I looked HARD at going LS. Even a 4.8/4L60E would be great in this little truck. The problem is, that would require new drivelines, mounts, transfer case swap the list goes on and on.

Since the Tacoma and Tundra share the same transmission and transfer case (albeit different versions) it really simplifies the swap. A few parts to swap between the transmission; front pump, stator, torque converter, valve body and bell housing.

There is also the cool factor of putting a Toyota V8 in a Tacoma. Can you all tell I like Toyota?!

Also, you had a 4.7 Tundra, you know how good this engine is!

I absolutely LOVED that motor! Never had luck getting an exhaust to stay together for more than a couple trips, so it often sounded like a racetruck with open headers haha.

I'm not disagreeing keeping toyota with toyota. Just that your swap looks more complicated than mine lol

The motor/trans is out and it fought me all the way. The motor mounts were rusted solid and I had to chop off the ears of the motor mounts with the sawzall.
