I installed the Nisei IC along with AMS lower piping. My car has the OE turbo, HKS 280 cams, 3” turbo back, stock air box (no MAF), Walbro pump. Some data from the AEM ems:

The stock intercooler consistently gained 25 to 30 degrees F using the data from the intake temp sensor (located in the upper IC pipe) when doing a pull through third and fourth gears.

With the Nisei IC, intake temp gained 5-7 degrees F under the same conditions.

The car went approx 0.3 to 0.4 AFR points leaner with the new IC.

Boost pressure did not measurably change. (I am using AEM closed loop boost control)

I am running about 23 psi peak boost, tapering to 21-20. The stock injectors are over 95% duty cycle worst case.

 

 

How is your idle with the 280 cams and ems? Is it still loppy?

 

good info

 

pics?

 

It's nice to see people posting their gains / reductions with their new mods.

What was the aprox. ambient temp during testing?

What was your actual air temp value?

Are temp delta's you reffering to, above ambient air temp?

Thanks.

 

Ambient temp was approx 60 degrees F for both the stock and Nisei IC.

Actual intake air temp started about 65 and went to approx. 100 for the stock IC.

The Nisei delta was actual intake temp, in other words the intake temp started about 60 and went to 67. Ambient was approx 60.

 

It's lopey, but a "good" lopey. The car does not stall when the AC is on at idle.

 

Interesting findings......

This is what I measured. If you follow the trend line, your inlet temps were much warmer than mine, however I didnt test in as cool conditions as you did.

I have a stock ic system & air box, tested in warmer conditions, used an exposed junction t.c. within the plenum.

I wish more people would post thei results / findings,

 

Richard,

Glad it worked out for you. Sorry about the shipping delay while we had the end tanks polished. Let me know if you need anything else.

Wow, that's a 33 degree difference in intake temperature!

 

that's good info Richard

 

you've done good richie.

I want that FMIC so much...

Now, does that FMIC fit the stock lower pipes? or you have to get a new one that fits?

 

Pics?? This might be one of the better FMIC's out right now for our cars.

 

yeah it fits the stock pipes and comes with t-bolts and silicone couplers. it is very well designed and not just a spearco core with endtanks welded on.
