Im planning to install the nisei intercooler hard pipe kit on my evo 9 soon do any of you guys know if you need to get a tune with installation of hard pipes so far my only mods are a turboback exhaust.

 

No, you don't, and you'd know that if you did any reading or searching.

Ask newbie questions in the newbie forum.

There's no reason for IC pipes to be your next mod after a TBE. You're spending a lot of money to get very little power so far. You're missing the two MOST important and LEAST expensive mods.

 

^^^ at least he will look good under the engine bay Warr. Before you spend that money on the intercooler/hardpipes. Get a fuel pump,mbc,tune you will be way happier and make way more power!.

 

The stock intercooler piping actually isn't that bad. Although the lower icp is slightly more of a restriction than the upper. But I've seen people make decent power w/ the stockers including myself. Like mentioned above, get a boost gauge, mbc, fuel pump, drop in filter and then tune next.

 

+1

 

i've made 350hp/375trq with all stock pipes, including stock intake/airbox.
you actually should shoot for mbc and a tune. that would be your next mods, get an intake if you wish. i doubt you will get good gains with an intake at your power level.

 

change the lower...no need to change the upper....yet

 

2 things mentioned here are wrong. No a fuel pump is not needed on a IX for a bolt on car. Second an intake does yield a gain. Just Have to make sure you get the right one. I suggest getting a a buschur or apexi filter, a halman MBC at 24lbs. and a tune to finish it off. That should hold you over for a bit.

 

that is exactly what i have but you get used to the power easily lol i want more power i have on my IX a Drop in KnN, TBE, Walbro 255 and a halman set @ 24 psi but it tapers off to about 20 at redline.

 

Next would be a ported and coated manifold. That is the cheapest gain and reliable. Better manifolds out there but they get expensive. I would definitely get an 02 housing.
