Look at my build thread. Im building a reliable/Econo/ Mild DD build.
You can use P30 pistons to get about a 11.5:1 with 82mm pistons. or JDM ITRs
i thought P30's were 81mm?? but correct me if im wrong
the je pistons will cost about 900 for the je parts. about 430 for the rods. good call on the rod priceGet nippon Pistons on ebay. You can get them in 81mm and 82mm.
I would go 1mm over bore to clean up the walls. and they fit on stock rods.
With JE forged pistons you will need forged rods because forged rods dont fit cast pistons. 400 for pistons, 4-500 for rods. you dont need Forged rods for a Mild N/A build.
The weakest link in the stock rods is the rod bolts. They use the same rod bolts as D series.
i know theyre pricy but do yours come with skirt coating? skirt coating is proven to increase performance. also, can you order any type of piston you need for different applications? hey, i'm all for saving money but i'm not going to sacrifice performance for cost. for a mild build-- maybe. but for a best of the best-top notch build, its gonna cost a pretty penny. i once had a guy in the machine shop tell me Eddy the top machinist who has done work on thousands of motors starting in north carolina in 1968, was out sick in the hospital and wouldnt be able to get my block machined for a while. (Eddys a diabetic). i could have said let the new guy do it, but that guy didnt have experience. i waited a few days for Eddy to get back to work. even though the new guy would have been cheaper. you just have to pay big bucks for some things.I would never pay 900 for 4 JE pistons.
I payed $430-450 for JE pistons on my turbo build, So i dont see why he would pay 900. Thats a hell of a lot.
For forged high comp I would rather buy Arias pistons and eagle rods.
yep i agree. although i never thought about extremely high compressions like 17:1..can these stock blocks be machined and customized to actually handle that kinda compression? and in my experience i have used stock crankshafts i know guys running stock cranks on 1000 hp (not hondas obviously) but the honda oem cranks have been easier to work with and the handle hps of like 350 in a few engines i know of. i built one for a guy that did 278 whp on the stock crank. that was an NA engine too.
Yep they are coated.
I see your point but it looks like he wants a reliable DD and not a track engine.
Now if he wanted a track engine that needs every last drop of HP I would have Told him to buy 17:1 pistons, forged rods, LW forged stroker Crank, 87mm Sleeves, P&P head, 1mm Oversized valves, custom cams, custom rockers, ITB's and tune it on straight meth.
yeah sleeving the block i know about. only went with 13:1 compression though. didnt want to push it because the guy i knew was going to drive it on the street. hes the kinda guy who runs his mouth when hes drinking and will get in his car to show off. then he'll wreck or blow up the engine ant try to get me to warranty his engine. as you know warranty and high performance dont usually come together when youre talking engines. any how, that engine was built conservatively.Yeah when you re sleeve the block you can run insane comp like that.
Stock crank can be used up to 350-400 with no problem. Looks burned but it had a bit of used oil on it from when I stored them with the rods.
The good things about these pistons is that they are coated, the pin bosses are drilled to improve oiling, and are OEM quality for 150 new with rings. Super pistons for the price, and I know of a bunch of people using them with zero problems.
YCP and RS machine pistons are awesome too.

what do you recommend for starters with high compression engines in the 17:1? what brands have you had good experience with?
