Initial impressions of the Nisei intercooler:

***EVO IX****

Amazing fit and finish. HUGE. Bar and Plate design, with cast endtanks. Considerably heavier than stock(makes sense b/c of the construction and size), with a big supporting bracket on top.

Battery kit:

Excellent craftsmanship. The black finish is smooth as glass and does not mar easily. the base is adjustable to accomidate different battery legnths.

Intercooler Pipes:

This is a 3 piece design, with the same mirror like black finish. I have installed the Injen, RMR, and Helix kits, and the Nisei kit is... by far... the highest quality kit(RMR next in line). The welds are impecable and all of the mandrel bends are flawless. T-Bolts and Hose Techniques couplers are standard.

 

so sexyyyyy

 

Install Tips: ***ALL INSTALLS APPLY TO EVO IX***

If a detailed step-by-step is required, let me know I can post it.

Intercooler Pipes-

Pretty standard. Does not fit with the stock battery. The pipes have mounts similar to the stock intercooler pipes on the lower two pipes. The '03 has a different mount so be sure to specify what the year of youe evo is. Don't tighten the T-bolt clamps until you have correct alignment. This kit WILL fit with the stock IX intercooler, using the stock couplers. Putting the lower on will require taking the front fascia off or really little hands...lol

Battery tray/Battery-

This particular tray has multiple pieces, and top quality black anodized hardware(hex bolts). The tray mounts to the tranny mount in the stock locations(2 larger screws).

So far everything has been smooth....until now.. You have two options: 1. put the pos terminal toward the front of the car, and stretch the wires by releasing the clips on the loom... or 2.Get a "quik connect terminal" from Pep Boys(7$) and snip the neg terminal off and replace it with the extension(as seen in the Pic) and it fits very nicely.

Intercooler-

Remove the front bumper(3 screws per wheel well, two on the lower front, and 6 from the top) Remove the bumper beam(4 screws) and the stocker. Undo the loom clip for the fan. If you are using the Nisei Pipes (which I reccommend for support..b/c of the two mounts) you must remove the lower pipes... install the intercooler..(I supported it w/the stock jack and a block of wood while I worked) and then put the pipe kit(lower, both sides).

For the IX, this install will take some 'massaging', but it fits very well. Be patient. Do not over tighten the T-Bolt clamps. The fron bumper goes on easier than it came off

I will tackle the undertray tomorrow.....

DYNO numbers by the Weekend!!!!

 

more pics..some stock..some show nisei pipes to stock intercooler

The gold bracket needs to be removed...it is located behind the battery. This is necessary to free up room and loom...ha that rhymes.. lol

 

Wow everything looks great. My question is with Lower Intercooler Pipe, does it come with with nipple for the vaccum line or use the stock piece?

 

Do you mean the 1.25" port for the BOV? If so, yes it is on the underside. The kit also comes with the extension you see in the pic of the pipe on the floor... hope that helps

 

Nope I mean the one piece that runs from intercooler to the turbo, on the turbo their is black piece that attaches to the turbo that has a nipple, do you still utilize that or do you do something different?

 

nice man i want that front mount sooo bad!

 

Nice write up, NISEI is supposed to be like the best quality stuff out there and it sure looks like it is.

 

The Nisei quality really is amazing. It is worth the extra money. I know it sounds like a sales pitch...lol

As far as the lower... it retains the stock piece w/the nipple... so no more PITA install for a couple of extra inches of 2.25 piping from the turbo(like the other kits) just slip on the reducer coupler...and thats it.

 

Do you think the pipes would work with the stock air box?

 

Yes it does and thats why I want it.

 

Yes, they are designed with that in mind! I can't believe I forgot to mention that

Here are some more pics... close-up of the turbo-pipe coupler.

 

that looks great. I love how the FMIC covers the whole front fascia and the fit and finish look oem.
