Remember folks, oil is cheaper than a new engine.

While I appreciate the shout out in the video description I must criticize your technique for assembling the motor. People have had motors fail for being assembled more meticulously than you have here. Both crank diamond washers should be replaced, the crank pulley should always be countered when torqueing, and you never touch the diamond washers on the faces! Please go review my instructions and videos more in depth to help improve your future methodology.

I exclusively use royal purple in my tracked 2.5 swap. Not listening to the haters, its never failed me once.

You can. I couldn't and I did. Best decision I have ever made.

That’s a nice looking 69 Firebird behind you 😎

@fr3ub Ай бұрын

Thanks for the video, but there is too much shortcuts... there is two washers because one goes behind the oil pump sprocket, bolts are torque to yield, you are supposed to put a new one... you are lucky you didn't bent the timing tool or cracked the timing cover with the bolt while timing it (there is a tool to keep the damper from spinning), etc, etc :(

Which dipstick should be used? The 2.0 or 2.5? Amazing write up in your description by the way. I saved it for near future use! Thanks for the vid/info!! Super helpful!

What year 2.5 engine did you use?

How much to swap this into my b2200? I’m in Tucson!

@brandonwelsh2743 3 ай бұрын

This swap costs $5600 but you would need more work for mounts, custom hoses and all the wiring/ecu from a Miata .

@imchandler9951 2 ай бұрын

does anyone know if this 2.5l swap would have about the same process if it was in place of a 1.8l instead?

@imchandler9951 2 ай бұрын

or would it even work or fit ?

@UWrenchTV 2 ай бұрын

There are some differences in doing a 1.8l versus the 2.5l. Brandon is not sure just what the differences are but he's gonna do a bit of research to find the procedure.

Why do you hate royal purple. I’m on my third Mazda on the way to 300,000 miles in my passenger car with 10k oil changes. I just replaced the valve cover gasket at 160k and my motor still looks almost new . I don’t track my car though. Just run it up and down the highway everyday.

Why the hate on Royal Purple?

@brandonwelsh2743 3 ай бұрын

Never seen anything good from it, most of the time engines run worse with it in them. I’ll only use Royal purple to cool drill bits.

It hurts my eyes.... Using impact gun for tightening crank pulley that is hold in place only by positioning bolt .... best way how to destroy your timing cover. That M6 bolt screwd into aluminium cover is not suposed to hold that in place but only set position. You have to hold it against tightening force by tool. Also use new crank bolt everytime its TTY bolt non reusable.
