Ok before I post the question I completely understand that a front mount intercooler, even an ebay knock-off front mount intercooler set-up would free-up several ponies compared to a fectory s13 silvia side-mount.

With that said the question at hand is at what point does the stock s13 side-mount intercooler begin restricting horsepower from the breathability or the sr20?

I never noticed any difference from when I had a stock s13 sr20det at 12psi on the t25 with a fmic in my s14 to what I know have which is another stock s13 sr20det at 12psi on the t25 with the factory side-mount. To be totally honest it feels like I have alot less lag with the side-mount than I did with the fmic.

I'm about to upgrade to the oem bolt-on style gt2871r .64 ar on a s13 sr20det which is being rebuilt with forged internals (rebuild is necessary for the engine itself not for the turbo set-up) and was debating on if that would really hold back very many ponies and if it would possibly seem to have less lag since the smic piping is only maybe and inch and a half to two inches I figured it would possibly be able to pressurize the piping and the intercooler faster and decrease on some lag. But the the heat soaking from the turbo would come into play.

So the questions is does anyone actually know when the factory smic begins to severly restrict horsepower?
