Alot of guys have used nippon "turbo" pistons up.to 500whp with success. I have a set that ill be using in my new engine this spring.

Stay away from cast pistons.
This has been a free public service announcement. Thank you for your time!

That's rather odd...I don't see any members on here or know of anyone that has "Nippon" pistons making that kind of power. Must be the same folks who are glorifying those GARBAGE 1500 watt car amplifiers, ….smaller than the size of a paperback book. LOL

In the grand scheme of the costs of rebuilding the engine, a few more hundred dollars isn't going to matter, and at some point you'll find yourself wondering why you didn't just go with forged pistons in the first place.

Re: Matteggy's B18b1 Turbo Build- What are the advantages of Boring out the cylinder?
I love that lol I and dead set on forged pistons. I was only wandering because I’ve seen a bunch of people super confident about using them for an all motor build with good experience but I see these are “turbo” cast pistons so I was wandering what they would be like. Idk if I wanna get greedy and take the gamble so I might just settle with the deal on the rods and pay full price for the pistons when I know what size I need. Keeping my power goals in mind though, these pistons aren’t completely out of the question

MY experience with Nippons was not a good one. Would they have held had they not contacted my valves? Who knows. All I know is they hit valves and the valves were unharmed in any way but the pistons (1 and 3) split, as pictured above.. This says shitty piston..

Re: Matteggy's B18b1 Turbo Build- What are the advantages of Boring out the cylinder?
that sucks. i mean.. the pistons didnt break because of cylinder pressure so i dont think its a fair assessment. sure, a forged piston would have survived that, maybe a stock honda piston would have too, who knows. but the pistons didnt break because of normal use. they broke because they impact a steel valve at high speed. to date, ive not heard of anyone breaking these under 500 whp under normal conditions.

Re: Matteggy's B18b1 Turbo Build- What are the advantages of Boring out the cylinder?
I'm pretty sure the highlighted statement is why. That's the best I could figure myself. I am almost certain forged would have survived that for sure, heck, maybe even the valves. If you look at my pic I posted above, you can see the "bite" the intake valves took into the piston. Really not much at all. And the only 2 pistons that were contacted; were also the only ones to crack. I've seen instances where valves became embedded into the piston. Machined valve relief would have left me with room to spare in this instance. Putting this all together, the conclusion was drawn that cast pistons are just bad joo joo. Unless I was incredibly unlucky and got a bad batch. Lol!

Re: Matteggy's B18b1 Turbo Build- What are the advantages of Boring out the cylinder?
Judging from what everyone is saying, I’m probably gonna stick with forged unless something changes my mind at the last minute. It just seems like the value of forged pistons can't really be matched, even with my hp goals. Trying to do it right the first time. What I really wanna know now though, is your opinion on camshafts. I’m told b18b cams can take boost really well so I was considering a set of stage 1 n/a crowed cams, but at the same time I don’t want to question at any point after my build if my cams are sufficient or if there is valve float so I was primarily considering stage 2 turbo purposes cams, I just don’t know how they would affect my mpg. Remember, 25-300hp current goal. Any input?

Re: Matteggy's B18b1 Turbo Build- What are the advantages of Boring out the cylinder?
I already have my setup down for the most part. I have a gt28 T3 and I’m just trying to get all the basic parts together for it’s install. I wasn’t thinking about running all that high of boost, probably no more than 10lbs, 6 or 7 to start. I think the biggest components I’d need to get in line now would be the intake, fuel injector size, and a hondata. What other factors should I look at when picking a set of cams? I’m prepared to buy a new set of valves, springs, and retainers to match as well. Keep in mind it’s gonna be a daily

Re: Matteggy's B18b1 Turbo Build- What are the advantages of Boring out the cylinder?
alright I’ll see what condition my cams are in and decide whether I should get new ones or not. Will probably go with crower stage 1. I know you can’t really upgrade cams without upgrading the springs and retainers, but does it work the other way around? Upgrading the valvetrain with stock cams?
