You need 84mm ITR reps. You wont break 200whp with stock B20 compression.

so if i decide to upgrade pistons to itr 84mm. would i have to upgrade rods and arp rod bolts? cuz i was just trying to use a bone stock block with a fully built head. is there anything else i can do instead of modding up my block?

i wasnt planning to go all out with my daily driver.. i have a rs machine sleeve gsr bored to 86mm for my boost project. i was planning to run with the stock block set up for 6-12 months until i have enough money and time for the project. once im done with the rs machine gsr block imma just swap out the block, install the turbo. maybe upgrade some minor bolt ons but thats it. then its off to the tune. so what should i do for the most power but reliable until the 6-12 month period. what do you fellow hondatech enthusiast think?

I suggest you put the damn thing together with the parts you have and run it as is. Just don't expect 240hp.
