What is the best ?

Piston with longer height or shorter ?
Piston with longer compression height or shorter ?
Dish, flat top or Dome ?

What kind of advantage can I found to each one ?


Well, other thing that I wanna know:

Which pistons fit into a D16y7 (head & base)
and which ones NOT fit too !



Thanx a lot !

It all depends on what u are going for, all motor or turbo. If you want all motor then you will want dome pistons the higher the dome the higher the compression and for turbo you want a dish the lower the dish the lower the compression but you want to stay around 9.1 compression for turbo. Most aftermarket pistons will fit in like JE are good pistons for all motor or turbo.

- I wanna that my setup stay N/A !

- I want pistons not to much expensive

- OEM Honda D-series pistons will be the best I think

- I want to run my car everyday and I want less pinking as possible !

Which pistons will be the best and who fit right there into Y7
Which one will not fit there ?


Thanx !

Any suggestions ?

you can do what i did and put 12.1:1 arias pistons in it. they're much more reliable than stock pistons because they a forged aluminum where as stock pistons are cast. with higher compression you have to run higher octane and more fuel. if you still want the stock ones(i understand cheaper)i believe the d16a1 pistons will deliver a nice compression boost, but don't run lean, they'll shatter.

How much cost Arias pistons ?

If i run too leans with this pistons, do they shatter like P29 pistons ?

Does Arias pistons can support 50-75 NOS shot or very small turbo or supercharger ?

What kind of rods do you use & what is your entire setup ? (N/A or FI)


Thanx a lot again !!!

with rings and wrist pins i paid $550. they are ten times better quality than honda pistons, they won't shatter like that. the compression i use should be able to handle nos with forged rods. i didn't do anything to the rods when i rebuilt so i'm just running n/a. just make sure you have the proper fuel upgrades when you do any of this stuff. if you give me a better idea i can help you with that. what kind of motor? y7 right?

Go on it and see my project !

I got Y7, I want to keep it, & want to do:
Already have: Y8 IM, 4-2-1 pace seter header with custom exhaust, CAI, Accel wires and NGK Iridium


- Higher compression
- Bigger cam (maybe spring)
- Lightened flywheel
- Tuning ECU after all !
or twin carb, I don't know yet...

I wanna have a good setup, to push it down 14.5s - to high 13sec !

(between 140-160WHP ?)

I want to stay N/A but maybe sprayed later... !
I drive my car daily but if I consider drive means to me race ... !
But don't want to rev up 7000-7500 rpm...


Thanx a lot !

that y8 im looks very nice,gunmetal!!

well, if you're going to do all this and spray you are definitely going to need the basic fuel pump upgrade adjustable pressure regulator and bigger injectors. you'll only need the bigger injectors if you spray it. my setup right now is 12.1:1 arias pistons, stage 1 zex cam, i/h/e, msd 6a, aem regulator, and walbro pump. i run the pressure about 48psi and that is checked with the hose off. this is in a y8 with an auto tranny. you should check out exospeed for that cam you want though. there stuff looks good. i don't know if you have to worry about emissions testing but a dual carb setup on an obd2 year car will not pass. i don't know if i'd mess with the computer unless you were going to take it off the road. there just isn't enough you can do to them(since they are obd2) to risk it not being able to communicate with the tester. most chips just raise the timing which you can do yourself but won't need to really with the setup you're talking about, and then they can raise the fuel pressure which is better to have the regulator for anyway. i got a jetchip and i sold it and got a stock computer back for mine. it was a waste. hope this helps you on your way.
