So ye, I asked "excuse me good proprietor of this performance garage, how much would one pay for 1xforged engine?". The reply was "depends... how much of the engine do you want forging?". I have to admit, I hadn't really prepared myself to answer that. And I still don't really know. I passed out, but I think I was quoted £2500 for wosner pistons, zrp conrods, some arp bolts and obviously the actual rebuilding of the engine. I assume that included some cleaning / tidying of cylinder walls, etc. At that point I didn't dare ax how much to uprate the valves as well.
