Ok I have a friend that wants to put in Higher compression pistons. Its a b20 bottom end STOCK with a gsr head. The head has itr valves springs, retainers, and itr cams. His intake is a skunk 2 mani and DC header. So my question is what dome piston is good for this set up wanna get the most out of the NA and not wanting to boost or spray.. Which my biggest conserns are Piston to valve clearance when in vtec. I know that itr cams arnt all that aggressive but just want to be safe and dont damage the valves + pistons. LMK what you guys thinks.

 

Hmmm..... No inputs yet.

 

Bump.

Product description

I have a set of supertech piston 84mm 12 5 1 compression ratio 350 firm


Set of 84mm Oem Honda piston rings only one opened 130 firm
will post pics up tonight

450 for all




Would these be a problem in my buddys build?

 

BRAND NEW Piston set for:
Honda / Acura B20 with B16A Head (+.03 w/GSR B18C head)

Part Number : P4-H84-P5
Bore: 84.00 (Std Bore)
Comp. Ratio: 12.5:1


so yea it'll be a little higher compression than b16, but i think you should be safe, like you said type r cams arent that aggressive. that compression i think is with 3 layer headgasket if he uses a 1 layer it'll be even more higher.

 

ok i have a b20 block with king bearings and acl piston rings also with kms block guard but i have a gsr head but i want to do supertech valve springs with obx valves and obx cams ooohh yeah kms valve guides but my question is what stage should i go with my pretty much stock b20 block? ps on a budget

 

stock b20 block wont accept anything bigger than itr cams(or it will smack)

 

so the springs and valves are cool to do then?

 

or should i go with itr everythin ( valve train) i need some suggestion? and if i do go with some other springs what kind and valves. oh and what size lift on the valves and springs lol

 

And where are you getting this information?

Noooo. I would've NEVER guessed....

I love how people buy sh*t and THEN come into the forum and ask IF what they bought will be alright.

Ever thought about doing a little thing called RESEARCH before you start buying sh*t? Or is that just a lost art?

 

first of all i didnt buy anything yet thats y im askin question to u guys that kno more then me and second everyone starts somewhere dont act like u knew ur stuff out of the womb smart guy lol

and if think u kno it all go b a teacher to teach A holeanology lol

 

The OP is asking about higher compression pistons though. If changing the pistons you should be able to use as big of cams as he wants.
