I thought i'd share my experience with this place as they are a horrible and dont want anyone else dealing with what i have been..
I bought a R33 RB25det swap from them for 2200 shipped, good price. I received the engine and it looked to be in decent shape, missing a few things but nothing crazy.. I started to inspect the engine, did a leak down removing items etc, and i noticed there was some kinda rust colored fluid in cylinder 3.. I removed the head to inspect as i was planing on replacing the head gasket anyway. upon removal i found this
as you can see from the pictures water some how go into the engine and rusted the cylinder wall and the camshaft, it would need to be at least honed in order for it to work properly again, and the camshaft would need some type of repair.
i followed their warrenty policy i gave them my certification number and a detailed description and the pictures you have already seen.
Will at JDM engine depot is an absolute retard and obviously has no idea how an engine is supposed to work, he asked me if i had tryed to run the engine and got a little mad that i took MY engine apart. he expected me to run the engine and see what happened.. I couldnt beleive he said that, at first i wanted another engine i offered to pay shipping and he said that theres nothing he can do because i hadnt ran it yet... i mean anyone whos knows what there looking at knows that it shouldnt be run like that... im sure it would start, but not with out smoking or eventually wearing out the cam..
I could rant on about the conversations we had, he pretty much told me to deal with it, he offered me another camshaft from a non turbo RB and i wasnt sure if it was the correct one or not and he wasnt either... SO do yourself a favor and take it from me, DONT buy from JDM ENGINE DEPOT
