high compression pistons on D16Y8
I'm kinda broke right now so I think I'm gonna just go with an all motor D16Y8(yeah I know...it sucks). What kinda high compression pistons should I get. I don't need the best money can buy so I was thinking about getting those ones on ebay(I know they need to be more ferrous because aluminum has a higher heat index and can therefore harm your engine) which raise combustion to 12.9:1 or would it be better to get the ones from another d-series(like the d16a6--raise to 10.7:1). I am trying to do this the safest way possible so should i be worried about predetonation with the ebay ones(12.9:1) and am I going to need a tune??

You have to rip apart the block to replace the pisitions. By the time you pay for everything just to place them, your going to spend a good chunk of change.
Save your money, buy a turbo, slap it (low boost) on and call it a day. You'll get more power, just as relaible, and save some money.

i wouldnt buy anything from ebay unless it is a name brand that can be purchased elsewhere.
i would only use internals from a trusted company. (OEM Honda being one)
So if i were you, I'd run some higher compression stock pistons.
I'm not sure of the validity in this but P29's (d16a1) seem to raise the c/r to 12.6:1 putting you in a range you'd be happy with. But i'd be happy with PM6's (d16a6), then boosting later on.
but either way, piecing together a turbo kit is better money spent.

I think this the last post I get today so I better cover everything.
How do you figure it would cost more. I'd be doing the conversion myself. I think I can handle it. All i would have to buy is high compression pistons and rings and thats it. It wouldn't cost near as much as a turbo(with the complete kit, Ecu, good tune, low compression pistons, internal work, the list goes on). I don't have the money for a nice turbo setup, and besides I want to see what I get out of the NA d16y8.
What is it with this turbo advice, they are so expensive. I would love a turbo, but I can't afford it. Its all that tuning stuff thats expensive.
Sorry I can't repost at the bottom, used my limited post for the day. Thanks for the help. I read some NA d16y8 threads on another forum and its' not that great, so I guess I'll save up for a t25 turbo setup or something small like that. In that case could I use a piggyback and get away with it.

1. Pieced together turbo kits for d series run around 1000-1500.
2. people run stock d16s on 8 lbs all the time, no internal work needed.
3. an NA d16y8 probably wouldnt run over 150whp with what seems to be your budget. if you dont have the money for a turbo kit, you wont make over 150whp on a d16 NA.

Re: high compression pistons on D16Y8 (knockout)
Dont forget that when your replacing your pistons your going to have replace your seals as well because once they are on and you take the part off the seal is then shot and needs to be replaced. Also if im not mistaken raising c/r that high in a basically completely stock motor will cause it to run like crap it will need to be tuned yes and. I dont think some of the stock internals of this engine can handle that much more pressure but i could be mistaken. FYi turbo is always cheaper than going n/a they both get you basically same h/p in the end. but n/a takes alot more time and parts therfore more money to get it the same as running with low boost I mean with the gain goal your going for turbo is best. But if we were talking like 150+ Hp gain than going higher on boost means you need to rebuild the top end and when this happens you need to do the bottom also or its known to go. boost for lower gains is cheaper than N/A after all is said and done and your going peak HP that this engine can prduce than youve basicaly spent the same on both setups.
