Re: 2020 Supra B58 Engine Teardown - First Look - Better than the 2JZ?

Cost? Cost is ALWAYS a factor. The only cost-no-object vehicle I'm aware of was the Vector W8, where "better" always took precedence over "cost". You must be thinking of a different W8 that was developed in the worst location in so cal (Wilmington), barely paid (and often didn't pay their employees...

Re: dyno question

What do you have for a variable resistor?

I wonder if a VFD, Variac or other variable device could supply the power.

Re: dyno question

I have also looked into this. From the little bits of information I have found there is a significant bit of electronics required. The 24 volt truck control is not what people seem to use. Instead they rewire the coils in series? And then use a power supply of 192 volts. I don't know if the voltage ...

Re: Weld or putty

Drill with the smallest tap drill that will clean-up the hole. Drill through the water jacket and out the other side. Tap from the outside through both holes at once with a long tap. Insert a single threaded rod through both holes the same material as the head coated with some kind of sealant, maybe...

Re: Education time....what were these used for?

Possibly the same reasoning as the Yamaha cross plane crank on 4 cylinder.

Re: Mopar RB Crank Journal Spacing

What is your goal? To make one? My goal is to have a reasonably accurate CAD model so I can do a bunch of modals on it to understand what rpm the crank shouldn't be run. By reasonably accurate, I mean it will have the right physics but not be perfect enough to to send to CAM and make a crank. (It c...

Re: Mopar RB Crank Journal Spacing

Rick, I have several cranks at the shop. I will try to remember to measure a couple of them in the morning. Thanks for the measurements, Bill, much obliged. Diodedog, "two-piece" is another way of saying broken crank. The block, along with a new Bryant billet crank, is in Immokalee this weekend. Wh...

Re: Staggered main bearing sizes vintage GM

Seems like a very deep rabbit hole for engines making what power density? Maybe 0.25HP/CI?

The simplification of line boring aspect seems reasonable.

Most Race cranks are.

Re: What's with these goofy SBC rocker arms?

Application is standard spacing conventional small block Chevy. They are listed as being for 3/8" studs. Stock photos don't show any other parts included. No stands or pedestals or anything else. Apparently, you just drop them over a pair of rocker studs, adjust them, and go. I also don't see how i...

Maybe a case of someone finding out that things work different in real life than they do in a CAD program?
You have that backwards, a CAD model would show the problems precisely.
