Anyone know where I can find a torque plate for honing a sr20det?

unless the machine shop you're taking it to is really sloppy, you're not gonna need a torque plate for a honing job. If you plan to bore it, then yeah tell your machine shop to make one...OR check the roundness with the head attached without any of the bottom end attached using a bore gauge and correct as necessary but they come out pretty good on the sr's as long as you're not doing some crazy bores into the 90mm range.

I honed it myself. I just took it down to a 280 grit stone set. It was recommended not to go to 400 grit unless I had a torque plate. Just wanted to know where to find one cause I have a second block, and I might do that one too. I just honed it out to fit a set of wiseco pistons in, plus a .0035 wall clearance. I'll probably post the numbers of the build sometime sooon when I get some pics to go along with it.
