so i have a ls block and b16a head. i was going to run the p30 pistons either the 81.25 or 81.5mm size. on the ls rods, and thats it for the bottom end. now the top end is where my question is going to be mainly. im stuck between the CTR or ITR cams. i can get a set of ITR 2000 spec cams. i would like to know what i would be gaining from those over the stock b16a cams. would probly be running just a stock type r springs and retainers. and would like to know pros and cons of runing both the ctr and itr cams. and i would LOVE to push 250 with SP2 intake mani, throttle body not sure what size, fuel pump, and bigger injectors, i am open to suggestions on what throttle body size and what fuel pump/injectors to get.

also if you got a different suggestion about just my set up in general lmk i am open to suggestions. and i think i said everything about my set up you would need to know if i didnt im sorry and please tell me.

 

you will make more power with ITR cams rather than the b16 cams considering b16 cams have the shortest duration. you need to upgrade your valvetrain when using ITR cams. as for throttle body size a 68- 70mm TB will work. I do not think you will even touch 250 with the supporting mods you stated. to hit 250 you need a bigger bore block like a b20 or some sleeves, an awesome flowing head, some bigger cams, a hytech rep or something of that nature and a solid tune. if you break 200whp with your setup you should be happy with yourself

 

i was waiting for that lol. anyone know anything of scat crankshafts? descirbed as "fresh" on local honda forum, and would 350 be a decent price for it? i know the powers probly gunna only be around 200, but i can WISH lol. and its gonna be dyno tuned on a s100 most likely unless i find a sweet job, then it would be a s300.

and injector size sugestions? or fuel pump suggestions?
