I have seen the nisei engineering unit and it appears to be a fine fmic. However, based upon its pyhsical size, I would classify it in the stock bolt in replacement catagory along with many others such as TX's, Greddy, Perrin, Hyerflow, Sperco, etc etc etc.

The new Buschur race fmic is distinquished by both its sheer physical size - its huge and also by the very advanced core design.

To the best of my info ONLY Buschur is offering a huge "RACE" version fmic kit for the evo.

 

Yes, aluminum blocks will need to be sleeved, not just Honda or Ford all aluminum blocks need to be sleeved it's the nature of the beast.

 

How large is the new Buschur core? Also, what do you consider an avanced core design?

 

Some of the fmic coree out there were desgned as interrcoolers for concrete drills over 30 years ago. In some cases technology has not advanced since then. The core itself is the highest quality, newest technology.

 

Thats a lot of improvement for an intercooler. How do you rate an intercooler for hp anyway? IN my case I am still using a HKS Type S on my Evo 3 that still only made 615 on wheels ,would I expect a gain like this if I replaced the intercooler? I always thought if the intercooler showed lower charge temp then it would be ok no matter how much hp you're putting through. Guess I gotta reevaluate this area...

 

Do you have the dimensions of your core? Does it require trimming, etc?

 

Ok. The nisei engineering fmic is a RR intercooler "race ready". Nisei did their own testing against all other brands. And they alos have a challege. Send them your intercooler or any other "race" intercooler you have and they will outflow it and have better cooler "IAT"

 

When Nisei did their test the Buschur race intercooler did not exist. I'd be interested to see the results of a comparison test between the two.

The whp calculation is based uopn natural laws of physics. I am not remember the exact formula - you can do a search and there is some good info on the web on how to size an intercooler.

The eqasy way to see of your current fmic is working well is to log the data - IAT and pressure drop - that will give you a good idea.

 

Buschur can dislcose the dimensions if they wish

It fit in my car with zero trimming - drop in

 

What triggered you to replace the intercooler from the AMS to the Buscur unit?

 

I think it has more to do with the engineering of the original block, wether it was designed for F/I to begin with. Nissan SR20DET's do pretty well without sleeves and producing big power and being all aluminum. I just believe Toyota has the number one 3.0L 6 cylinder in bottom end potential and Mitsubishi has the number one 2.0L 4 cylinder.

 

The GT40R was too big for the AMS fmic - - the intake temps went out of control when I went over 650 whp

 

What temps are you getting on charge air with the buschur unit? I'm about to order one today!!!

 

On the dyno they dropped from nearly 175 degrees to 140 - I am waiting to see how they fare at the track, a good sized intercooler should drop in charge temps after the 1/8th as you go over 110 mph
