For you guys who want hard evidence, i have a friend who took some temps measures. That is on a CA18DET, which produces less heat than an SR20, and the intercooler is nearly the same. turbo is a brand new T25, set at 15psi with supporting mods.
on a 15°C day, temp after turbo is 157°C .
OEM SMIC, IAT is 55°C after a couple of pulls. It gets worse with every pull. He stopped when hitting 75°C. 208HP torque 29mkg.
random ebay FMIC, IAT is 19° after a couple of pulls, and stays there after some more pulls. 222HP torque 31mkg. more torque and power is still there up to redline, while it goes down at 5000rpm on OEM SMIC.
Now, try that on a 30°C day and watch your pistons melt.
OEM SMIC for S13 and S14, is rubbish. It WILL heat soak, even with a stock engine and no mods, as it is made for a standard driving style. Dont use one if you drive your car hard. ever.
that and it gets covered in dirt qui often due to its position and is hard to clean, much harder than any FMIC .
A better intercooler, wether it is SMIC or FMIC, gives more power AND more reliability. I think it is the ONLY part that does that. You really should use one.
