Nisei install/review
Nisei install/review

Installed was the 1pc UICP, LICP and intake, all in matte black. I love the look, but disliked the fitment, the lack of a solution for boost solenoid vent, super cheesy purple tubing and Autozone filter for the crank case breather.
Most everything during the installation was off by a little bit and that little bit would throw off the next thing just a little bit more.
Here's some examples of welds:



Here's the purple tubing that came with the kit since the black tubing kit pictured everywhere this thing is advertised is apparently out of stock from the supplier, Hose Techniques. I did not use these horrible looking tubes:

I could not get a picture that shows the true color of this tubing. It is purple in person as others who've received the same kit can confirm

On this intake pipe, notice the shelf made from welding an oval to a circle hole:

This is just the BOV return to the intake so it's not very important as far as "laminar flow" and all that is concerned.
Now for the fitment... the LICP was moderately easy to get on. The only complaints I have for this is that a hose coupler from the IC outlet to the LICP is not supplied, you're supposed to just reuse the stock coupler, and although it fits in well by itself, it interferes with the stock air box. I've seen plenty of pictures of this with the stock airbox on, yet after installation, the bracket that holds the stock airbox up actually touches the pipe right about where the elbow coupler to the throttle body starts. There's no way around this that I could see since the pipe is physically mounted to a bracket not more than a foot away from the contact area, and the bracket for the stock airbox only bolts up one way. The other fitment issue was reusing the stock BOV, now located below the stock airbox, would place it right up against bare metal. The solution to this was simple: cut some of the BOV return hose to basically "pull" the BOV away from contact. Only an inch or so had to be trimmed so this isn't really an issue.
The other fitment issue was the 1pc UICP:

Does not line up.

Preventing the holes from lining up.
I had to hold the UICP up and then bolt it down, which had to have bent the bracket to fit since the piping didn't crush in from that contact area circled.
There's so much free space available to get rid of this contact area... if only the mandrel bending could've been calibrated to accomodate:

If I were to do it over again I wouldn't have gotten the Nisei. Jedi@Maxum was great about customer service... whoever replied from Nisei, which I'm assuming was Kevin, didn't really seem all too caring as others have said before. When I asked why the kit is being marketed as having everything in black in every marketing picture I had ever seen yet when the kit arrives it has cheesy purple hoses, all I got was that Hose Techniques has no black 10mm or 6mm hose in stock. Nisei would be willing to send black replacements when they get them if I were to pay for shipping
Sooner than previously expected, I'll probably get rid of this intake tube for one that has bungs for the crank case breather/vent and the boost solenoid vent.

Circled is the solution to the stock air box bracket rubbing on the LICP. It's a small length of 10mm hose sliced down the side and then wrapped around the edge of the bracket that contacts. It's only a temporary solution until I get another bracket and cut that section off. The OEM LICP has 3 mounting points, and the Nisei has 2 mounting points. The one that's no longer in use is on the stock airbox bracket, and this piece has about an inch of space from the Nisei LICP so it's not a concern for contact/rubbing.
In the end, you get what you pay for. There's a reason why parts like what AMS offers cost considerably more than parts like Nisei offers, so if I ever swap everything out for AMS piping I'll update this review to compare.

Regarding the fitment issue of the IC piping, I did not have this problem. Neither did my friend who purchased the UICP. I would contact Nisei about the fitment issue. Either that, or slide the bolts in first, and then install the couplers and see if that fixes the problem.
As for the intake, you know that it would not come with a bung upon purchasing it. If you did not, then you did not read the description. That is your own fault, not the manufacturer's. Nisei is providing a low cost substitution for other intakes on the market. Now if you had a boost controller and a catch can, you'd be fine. Even with AMS's intake you have to pay extra money to have the bungs installed.
Also, the catch can would not solve that issue. The crank case should connect to a vacuum, which is exactly what it does on the stock intake. My solution for this is to get an AMS intake and have those extra bungs welded on, which would also get rid of the stock air box with its bracket so I don't have to worry about that rubbing on the LICP anymore.
That's why I'm taking it for what it is. I did complain about the purple hoses because that was the one part I felt was unacceptable. Jedi@Maxum did his best though with the given situation.
So your not happy with the product?
Hrmm seems likes Nisei have some Quality Control issues... shame because their gear LOOKS and WORKS awesome...
Personally being international I can't take the risk of getting a dodgey part... shipping is an absolute killer so getting it wrong aint gonna be good
hehe
This is why companies like CBRD who take extra care are given the thumbs up by me

I have the UICP and am currently lookign at the LICP and intake pipe... While the UICP didn't fit 100% perfectly, it did fit well enough that it looks good and functions properly. It just took a little work to get it into place. This makes me second-guess getting the LICP and intake pipe though. Especially if they weld an oval to a circle hole... Overall I am happy with the UICP though. I'm just not sure I want to risk it on the LICP.
My Nisei UICP did not fit dead on as well. It stretches the hose to the turbo towards the passenger side. The holes on top of the radiator support did not match up either and I had to bolt them down first, then attach the couplers to the turbo.
I have one of the first UIP from Nisei fit and finish is excellent. Maybe problems started popping up when they went aluminum only. Never heard of anyone with the steel one complain.
