Im going to be building my b16b and im gonna be getting twm itbs tuned with hondata and upgraded fuel stuff. My question would be should i upgraded the valvetrain and and the bottom end(aka rods and pistons). I wanna generate about 230whp. I know ctr internals are good outside the box but i really dont know where to start on upgrading the internals. Would blox and skunk2 be better the ctr cams and springs and such? Also i have another question im gonna be keeping a/c with this setup is just an luxury im not willing to give up yet would i run into problems with the a/c setup and itbs? I know the dont have anything to do with each other i just havent seen any setups with a/c. Please dont hate im just wanting some info about itbs and yes ive search didnt find what im looking for.

 

good luck getting even close to 230 on a b16.

if you did any research youd see that even 200 is a task in itself. if you want 220-230 build a 2 liter.

itb's are not a power adder, and i would be amazed to see ctr cams and valvetrain make more then 175ish whp.

 

I think +60hp is very achievable with building the motor. I did do alittle reseach i saw a b16a with 206hp with itbs.

 

watch the omniman dvd.

then try and find an example of a 210 or greater whp b16.

again why focus on itb's? they dont add power.

a b16 is not the platform you want for that kind of power end of story.

 

You mean more like +95whp. Most b16a's make 130~140 whp SAE. The type of build required to hit that type of number is not going to be streetable and you won't find the parts combination in the all motor dyno thread. Like Killerpenguin21 said, it will be more feasible and cheaper to go with a 2L setup.

Just to let you know, yes, you will need to replace the rotating assembly(rods, pistons, crankshaft), valvetrain, intake manifold, camshaft, header, exhaust, valves, etc. You will also need an electric water pump and dry sump oil system. Your compression will determine whether you run a gas or methanol. This type of build is going to require an expert assembler and tuner. Also, it will require some of the best parts available (some may be custom) and a completely custom induction and exhaust system.

 

ITBs are for throttle response and a flat torque curve, not HP, unless they are a very highend ITB like jenevy or kinsler, but your gonna pay some bank for them.

 

you first need to decide what is more important to you. having a "ctr motor with ITBs" or making 230hp. because youre not going to do both.

if you want 230 it will be a 2 liter B series with headwork and the normal "fixings". if you want a B16B with ITBs you can have that, but it will make 200-205hp, about 125ft lbs, and will cost even more than the 230horse 2 liter.

 

but i have to clarify...none of us who responded in this thread really know what were doing.





LOL

 

i just want to throw in a little tidbit from overseas (japan)...the first thing everyone does to their B16B is put a B18C crank rods and pistons in it.
