What do you think would be the best pistons for my car. People keep telling me ITR pistons.

 

please be more spacific about what you want to do. Is your build going to be a All-Motor build or Force Induction.

 

All motor

 

what is ur budget including tuning and what not? if u got the cash and arent worried about gas TODA!!!

 

Im just looking to get some more power out of my motor

 

I would suggest ITR. Good price and nice power gain out of them.

 

what about rods?

 

stock with ARP rod bolts, aftermarket rods dont fit OE pistons

 

If you have the money, go with CP pistons. They are the nicest pistons that I have ever seen, and are available in several different compression ratios depending on your build. Also, some of the sponsors will have good deals on them if you keep your eye out for them. Good luck.

I'd recoment the endyn rollerwave piston ftw!

 

i would go with some p30 pistons higher compression than itr's
you can pick some up pretty inexpensive too.

I just want to know what pistons that will be best for a all motor GSR? I will probaly go with Skunk2 cams, valve springs, valves, and retainers. Just trying to get some more horses out of the GSR. Might get some ITBS or make a set.

 

well if you want to make more power out of your GSR tuneing is the key..you can have all those aftermarket mods and your car will still run like crap. once you start thinking about getting all those internals done you better have a good fule management plan. I bought some SRP pistions on ebay for pretty cheap 425$ 11.3:1 compression ratio on a GSR head. and i think its 12.1:1 on a Type R or b16 head. haven't had the chance to put them in yet because i can't affored to have my car out of commission for that amount of time. school and work. but yeah. tuneing man...really look in to that!

 

itr

 

i have the ctr pistons wit s2s2 cams etc. and its running real good

 

gsr motor lol

 

how reliable is the motor going to be with say the ctr, or p30 pistons? for a daily driver? and if you do just the piston swap, will the gains be noticeable? just curious...

 

i would definitely slap on sum b16 pistons..= higher comp then itr and cheaper

 

and the gsr would be able to handle this as a daily driven car?? i think the b16 pistons would raise the compression to about 12:1 right?

 

What is the bore size of the CTR? can you get them oversized? I know a stock B18C1 pistons are 81mm

the standard bore size is 81mm

but i would suggest P30 pistons because they will give you a slightly higher compression than itr, but not as high as the ctr pistons

 

with the p30's, you would be around 11.5:1 ratio. and the p30;s come from the jdm b16 right?

yes they are from a JDM b16

and will skyrocket your compression. Search the all motor forum for why, I can't remember, but all the compression calculators online are wrong. Your actualy compression will be at/near 13-1 IIRC

not true, your compression will not even be above 12:1, most compression calculators are in the general correct area of compression plus or minus a few points
