As a matter of fact I have ordered the relocation kit from www.summitracing.com it's part number TRD-1113 . It's less than half of the cost of the Greddy unit.
Although on the web page it doesn't show the MKIV supra as an aplication when I called their tech support number the tech told me that it is the correct size and thread pitch.
I'll try to keep everyone posted when I receive and install it.
I have the Greddy relocation kit. The quality of the parts was excellent. and the install wasn't bad. The aluminum caps also provide sender mounts for oil temp/pressure gauges which I hope to do in the future. I didn't do an oil cooler. Pics would be difficult to take because the fittings and hoses are all buried underneath the intake plennum.
