ok right now i have a stock b16 and i read up u loose power using a ITR intake mani

But what if i was running itr cams/STR fuel rail/69mm TB/velocity stack/ 3inch piping for exhaust

so my question is with these mod's will itr intake mani still lose power or will it actually increase or stay the same as the b16 stock intake mani

 

hard to say, but the mods you have done will definilty shift the power band a little higher. So upgrade to the ITR manifold is probably worth it.

Will it gain ? I will probably think it cant be worse than the stock one.

 

thats what i think thinking but i read up on all this itr intake mani and got me thinking

thanks for the 2cents

 

i want to say if you throw the ITR mani on a stock motor it will loose power but with all your supporting mods, throw in a tune and i would not expect to loose any power but like DVDr said the power band will be higher, did you get dual valve springs to go with the cams and higher reving?
