Hello guys i want to ask you something...if i used vitara pistonsa and rods kit in my d16z6 with d17 crankshaft and y8 intake and reprofiled camshaft and 4-2-1 header exhaust with programm in greedy ultimate without turbo how much power and torque take all this set?
It is good to use vitaras pistons and rods kit without turbo?
 
Your compression drops to something below 8:1 I believe. You'll spend a ton of money and lose a TON of power without taking advantage of the setup for boost. You'd probably lose 20-30% of your current power if you did that. Pointless.

Because i dont understand you mean that i loose very much power if i used vitara pistons without turbo? And what aftermarket maybe or other type pistons with this set i used? For more power?
 
You need pistons that will keep the same compression or raise it slightly to make power NA.
 
The vitara set up is used to lower compression cheaply. If you don't want to go turbo, these are not the solution you want to use.
 
Yes correct! But i ask again if you know with this set what pistons i can use!!
 
what are you actually asking ? like this is pretty common knowledge stuff here like if you can look up the parts list of dream build together then what info are you missing ? your car probably wont run n/a with viatra pistons if it does it will very poorly

I'm not sure that you're understanding the point of the Vitara pistons. They are not a power adding mod by themselves. They prepare the engine for the turbo setup by lowering the engine's compression. Are you asking for a set of pistons that you can put in first that will add power and then add your turbo later for more power? If so, you need to do more research about turbo setups. You can buy pistons that will RAISE the compression and add more power by themselves, but a raised compression isn't necessarily ideal for turbo.
 
I think he's concerned with valve clearance since he's using the D17 crankshaft which has a longer stroke length than the OEM D16 crankshaft (94.4mm vs. 90mm). @Mour_Paolo, you should shoot for at least 10.0:1 - 10.5:1 static compression ratio if you don't want the car to feel like a turd.

CP makes a variety of pistons for this engine. This would be a good place to start looking.

why use the d17 crank... like pointless seriously even for the longer stroke you have to have shorter pistons to not smack the valves they are already super interference off the rip lol
 
if you change the crank, you need to change the rods too and consider any deck height differences.

Ah yes, I did miss that part somehow. Thanks.
