I'm planning on building another 200 turbo. Has anyone used the 1jz rods in a build. If so anything to be aware of? The plan is to do all the mods on this block that I was not aware of on the first build .
 
fast64ranchero and several others have used the 1jz connecting rods.
Do a search for "1jz"
The 1jz rods big end width is wider than the stock rod width and the journal size is smaller so the crankshaft rod journals will have to be reworked.
Will also need custom pistons.

How well did your first turbo 200 work?
 
Check with fast64ranchero to be sure, but I think that he had the crank grinder, grind the crank to fit and left the rods alone.
On the custom boost rated pistons the thinner metric rings are better than the stock one's but make sure that you can get rings in the thickness, material and size you need before the piston is made. Get the upgraded stronger piston pin. You will like these rods because they are floating and you can take them apart and assemble them yourself. Only overbore as needed to clean up no more.
You could offset grind the crank some but the bore is short and the pistons already come more out of bore than I like as is.
Figure the pin height so it comes out at zero deck. Your piston dish will need to be figured out to get the compression you want to run. Give the crank grinder a rod with bearing so he can grind the crank pin radius as large as practical, the crank will be stronger.
