Ordered rotors, pads and the spacers today. Hopefully I have them by this weekend. Has anyone had to use thicker copper crush washers for the stock brake lines, or had any issues with the bolt bottoming out?

The first time I did my HG I left the block in the car and used an OEM Toyota HG, put the new dowel pins in, had my Dad help me drop the head back on then inserted the studs through the head. It's a pain in the ass because you need to put gasket maker on the front part of the HG and if you drop...

They fit the calipers I bought on ebay, I'm not sure why their 'verify my car' doesn't work for any of the cars I tried (2001-2005 S430s and S500s). But, they fit the calipers I bought. I did do a bunch of part number searching before I settled on that website.

http://www.ecstuning.com/ES1654023/ Those are the right bolts, I bought 4 and they shipped pretty quickly. Test fit today, they fit in the knuckle and are the correct thread pitch for the calipers.

http://www.driftmotion.com/ARP-100-7715-p/dm2088.htm ARP wheel studs for the MK3/IS300/MKIV. One inch longer than stock and ARP toughness.

Background info: I have FD RX7 (16") rims on the front at the moment, with the longer IS300 studs and a 10mm hubcentric spacer (because the FD rims barely rub against one of the control arms at full lock without it). Picture of stock caliper: I took off the passenger wheel and...

Why would you want to swap the weaker 7M internals into the TT box? Or did I misunderstand you? Also, I've seen that the A650 transmission pump is a drop-in replacement for our A340E pumps, and it has a larger pump cavity therefore more flow. Something else to look into!

When I talked to ATFSpeed they said the 2JZ TT A340E was the only A340E that has a 5 bolt planetary gear system...the rest are 4 bolt gear systems. When asked further, he said there's no way to swap them over. They also have less clutch packs like you said. I'm interested in the greater number...

Thanks for the info! I didn't think about fields outside of car manufacturers. I could see FEA testing being done on structures rather than a seismic table, that would be tedious.

A bit of a hijack, but that was fun :biglaugh:

I strongly disagree. No amount of computer testing (excusing situations where its the only possibility) will ever be as good as real world testing. Not every part is FEA tested, every part IS however physically tested. Unbalanced mass can be calculated easily. Any force, torsional or...

First, come on, go look up 'argument from authority'. It's getting annoying. That shit belongs in a church, not in an engineering discussion. Very little pieces of the car are actually tested in any type of FEA analysis software. Most of the parts are modeled for fitment, and most are...

BS in Mechanical Engineering Technology here, from RIT. Why can't you look at this situation objectively and calculate the critical speed of the driveshaft yourself? If you want to put all your chips into the 'OEM' bag just because you think their solution is the best under all scenarios be my...

If you read into my post you'd realize I was making a statement regarding inferior products. We're on the same page. edit, because I don't want to make a third post in a row: my driveshaft is right around 42" long (why is everyone quoting wheelbase length in this thread? That has nothing to do...

Your concern is appreciated but your argument solely revolved around the fact that you believe that OEM manufacturers have it right because they have more money and are probably smarter than us. Go look up what an 'argument from authority' is and try to understand why what you're saying doesn't...

I can post videos from youtube showing turbos exploding and rims falling off, that doesn't mean they should be avoided like the plague. That's the result of either a defect or of an impact causing damage to the shaft...no excess speed, excess power or excess rpm. Scare tactics shouldn't be the...

Just because Toyota did it doesn't mean it's the only way that anyone will ever be able to do it. I think this is called 'argument from authority', correct? You could try doing some calculations on critical speed for the length/diameter of the aluminum and steel shafts and see where 'safe' is...

Shifter should be in the same place, not sure about the speedo. Rollus: thanks a ton for the information! Just to confirm, the torque converter will swap right over (with the bigger bellhousing)? I thought the spline count was different on the input shaft. *And* I thought the flex plate bolt...

Bolt pattern different, or...?

I bought an aluminum one piece DS from shaftmasters in July of 2008. Its 20 lbs lighter than the stock unit (most of which is reciprocating weight) and it's been great since then. Noticeable difference in acceleration and its balanced well so it runs very smooth.
