i currently have an EM1 and im very interested in getting
a ITR intake manifold...but would i have to dyno tune because
of the change in air flow or is it just bolt on without tuning?

 

i'm guessing your n/a and i would not tune if your only doing the im, you won't see much gain if you don't tune, but i would try to do a few more mods(header, tb, intake, cams) before you spend the money to tune, than all the mods can work together and you'll see a gain. it won't lean the motor to a point of harm enless your boostin

 

you should be fine not tuned, but i would def get the rest of the bolt on's then tune

 

ya i was planning on getting more bolt ons before the tune

but it would harm the motor if i boosted??

 

Honestly theres no need to tune just for bolting on a intake manifold. Its not like u are modifying the engine enough where you need to adjust ignition curves, A/F ratios, etc.

Depends how much you plan on boosting! before boosting, I would get more mods bro that will aid you and the turbo setup. More fuel, more spark, high lift/low duration cams, etc. When you boost, your engine demands alot, even at a measly 5-7 PSI. If your A/F ratio isn't correct when in boost, get ready for strange noises and to spend alot of money to make up for what wasn't done right the first time. For example, I always have customers at the machine shop who ask me "how much power will I see from the PnP job you did" and honestly, I dont have an answer for them if thats all they ask and dont tell me anything else. Bolting on a head thats been heavily worked and is about to flow about 20% air will need more fuel and spark to compensate for the added air. So same thing applies to you, if you plan on boosting and cram all that air in the engine, then like i said before, make sure you have the proper parts otherwise that time and money was wasted. good luck on the build

 

im definately not boosting anytime soon but thats good info for the future but i have planned to get more mods before anything else

the ITR intake manifold tuning question was cause me and a friend had different opinions about the airflow change

thanks for help and anymore comments would be appreciated

 

"I chose to use an ITR intake manifold and the larger ITR throttle body because they just dominate the B16 manifold past 6-7k. But, on the downside, as a general rule, the B16 manifold makes more power upto 6-7k. It just really depends on where you plan on making power"

i decided to get it its a jdm type r intake manifold with ported intake runner
