Alright so I am installing a b16 head with skunk2 cam gears, b16 cams, supertech flat face valves. Supertech vvalve springs, super tech retainers, skunk 2 proseries intake mani, sard fuel pressure regulator, and golden eagle pro series fuel rail on a stock b18a1. Will the car run like **** if I don't tune. or will it be prone to have problems if I don't tune, or will it be alright? Is it recommended to tune?

 

come on man you know the answer to this question.

How do you think a stock ecu will handle all the modifications not to mention a head and block that never came as a package from the factory.

Get that thing tuned ASAP unless you like blown stuff.

 

Alright man I wasn't sure I've never done such a build....so do u think this set up after tunbed will be reliable?

 

With the modifications you have a properly base maped ecu should be just fine.

 

If you built it properly.

 

i would get it tune whether it runs bad or not. you're building a ls/v. i've seen people who slaps on a vtec head and call it a day with no problems but i wouldnt recommend it. you want the motor to run at its fullest potential, if not, then why build it....your call cuz its your money and time...

also, why upgrade the valvetrain and not the cams? b16 cams are weak. should at least get itr/ctr...you'll get more power out of the build.
