Re: What is the best forged piston and aftermarket rod ?
Diamond, Ross, Venolia, JE, Wiseco, all make a good piston for our engines. IMO, Venolia pistons seem to be very old technology. While other piston manufacturers usually incorporate technology changes, their ring pack, design, might as well be from 1985 (lol). Robust, but heavy. JE's are almost always lighter than everyone else's. I have a set of JE's for a Masi 16V application. Asymmetrical design, very tight ring pack, very light, upgraded pin and rings were available options. They made me what I wanted, as opposed to making me something they thought would be best. Ross used to take FOREVER to make custom pistons so I gave up on them. I can't wait 6 months for a piston order, EVER! Diamond while nice, seem to have issues getting what you want. About half of all my Diamond piston orders either had to be remade or sent back and re-machined! Made correctly, they are very good too. My experience suggests operator error is a very real deal with Diamond. My opinion, JE's best bang for buck. Wiseco's use a ring design that locks you into using their rings. A very good piston though.
I differ from the others in that I won't use a late TI/TII/TIII/TIV rod unless I know it's history. I've seen to many TII rods that have been around the block one to many times. Spending $200+ resizing 30 year old rods, when you can get a NEW, stronger, lighter, better hardware, 4340 forged, CNC'd, perfectly balanced & weighted, better pin oiling, current technology rod for a bit more is money well spent in my book. Most of the H beam designs are around 100 grams lighter, yet stronger than a TII rod. Manley, Brian Crower, Eagle, K1, MAP performance, etc. all sell very nice rods with many options to fit many budgets. H beam, I beam, X beam, upgraded hardware, 7/16" rod hardware, are all options for these SRT4 rods. There also seems to be more bearing options for the SRT rods too. Most are import forgings, machined in US, but some are 100% North America product. The BC rods are my choice for best bang for buck. EVERY BC rod I've bought have been dead on as far as machining. They have at least three different offerings for SRT rods. The Sportman BC6169 being the cheapest.
