I love WORKS stuff, and plan on doing my whole EVO with WORKS stuff.
The Ohlins are calling my name!

Are there any plans on making a updated intercooler, & piping?

 

Why don't you make one @$$HOLE. Kidding.

 

just get the nisei kit!!!

 

nisei kit does not fit well with stock airbox

 

Fit is very important to me. So far all my WORK parts fit perfectly, my dealership
is a WORKS dealer, & all WORKS parts keep my warranty threw my Dealer.

I'm planning on getting quite a few more WORKS parts on my EVO & would like to
get better piping & a larger intercooler to go with it all. My hope was WORKS has something in the works.

 

Would you mind me asking what is the benefit of updated intercooler and intercooler piping?

I am curios to hear what some have to say?

 

larger intercooler = cooler intake air = detonation insurance & (some) more hp
smoother piping = more efficient flow = quicker response & (some) more hp

 

Works believes that the stock IC is fine for the stock turbo. A couple years ago, Works said that a water injection system would be far more efficient in cooling the intake charge while not adding any of the negative effects of a bigger IC(lag). On the other side, they still arn't offering a solution to hot intake temps. So, you might as well look into a bigger FMIC. I believe Works runs the Nisei FMIC on their track car.

P.S. The Nisei intercooler pipes "do" fit the stock air box.

 

Where to start...
1. of course lower IAT's that = more HP
2. Less heat soak =HP stays longer in traffic & low speeds
3. Some times you gain a little PSI due to less restriction

Pipes
1. Stronger then the flex lines on there
2. better hoses, should be smother then stock
3. On size tubing, better flow threw out the system
4. silicon hoses don't fail, and will have better clamps for higher boost
5. They will not flex at boost like the factory hoses.

On both, they also look better and give me a little more piece on mind when putting in a bigger turbo. Of course a bigger turbo = more heat

 

I'd like to see if they'll release a lower intercooler pipe.

 

hehe, that's what you get for soliciting opinions ... lots of opinions!! . Just some more points of interest, and these are totally specific to my experience so YMMV:

FMIC
WI is better than a larger FMIC for cooling, but it's an active system and thus can run out and/or fail. Since I track (or otherwise abuse) my car for hours a day, the passive FMIC solution was more attractive to me. I'm using an FMIC built by Kinetic Motorsports, and the pressure drop across it is lower than the stock one (less lag). On a hot day, my IC temps still go over 100F without fail, and I'm using the biggest size I was able to cram into the stock bumper. I run 100 Oct on the track for that extra margin, but it's too expensive for daily use - so given what I do with my car the FMIC was the more reliable / cost effective solution to guard against detonation.

Nisei Piping
I'm using the Nisei piping kit with the stock airbox, WORKS drop-in, and the FMIC mentioned above. It did reduce lag over the stock piping, and it's aluminum which is nice from a weight standpoint. Some re-drilling of the support brackets was needed on the lower IC pipes to get things to work with the larger FMIC (no problem there). However, the pipe that goes to the throttle body gets pinched between the airbox and the transmission housing. When the guys at WORKS installed my MR short shifter, we noticed that the pipe was very noticably dented (so much for smooth airflow), and one of the air box bolts is slowly working its way to a puncture. I have since placed some high density rubber around the pipe at the two trouble spots, but that's a bandaid. This may be MR specific since the transmission is bigger ... can't say. I have yet to find a pipe kit that actually fits well.

 

Are you still using the stock turbo? If so, I guarantee you that you will not gain power from the pipes. The stock pipes are made of aluminum and very well designed. They are not made out of SS which does not discharge hot air as efficient as aluminum.

Also, bigger diameter does not mean more power. On the stock turbo you are not pushing enough air to fill the stock pipes to the point of excessive extra pressure. In fact, you need pressure in these pipes to keep air velocity moving as fast as possible (physics).

Think about it as blowing air from your mouth in a big 5 inch pipe or in a 2 inch pipe? which pipe the air velocity will be faster and more condense?

Having the right pipe size and material is crucial. Furthermore, Intercooler pipes should not touch any part of the engine because they rub on there transferring heat in and from the engine.

Imagine if you ran 4 inch exhaust on your EVO, Do you think it will provide more power than the 3"? No it will not.

Regarding the smoothness of the pipes the EVO has smooth pipes with minimal kinks unlike other turbo cars like Volvo or VWs where they have much tighter hoses on some sections.

The only biggest kink I see on the EVO is right after the turbo and so far there are no real tests back to back on the dyno to prove that installing bigger diameter pipe will improve throttle response or even power.

Regarding the intercooler thats a whole new story. Larger intercooler means slower throttle response if comparisons were done before and after the intercooler taking in consideration that every thing remained the same, including boost and all supporting mods. Of course knowing the amount of air that you are pushing out is vital to match it with the right size IC.

Larger is not always better but choosing the right size is the way to go.

 

Any dyno sheets back to back after the Pipes alone to show us reduce lag and improved throttle response?

 

The stock LICP tapers to 1.5" and the stock turbo inlet is 2" no?

 

You're the first I've heard with fitment problems with the Nisei pipes. Did you see this thread on their website?

I believe they provide a nutsert & buttonhead for the airbox that you switch out so it won't rub. Not sure if the MR fitment is different but I've seen MR's with Nisei pipes that fit fine. You might want to call Kevin @ Nisei.
