My suggestion is build your own intercooler if your on a budget.Juniors mirage has a custom built intercooler that we ordered the core and endtanks from a reputable company.My personal experience i bought a ebay intercooler and it wouldnt hold over 17 psi.I contacted the company/seller about thier "40" psi rating on the ad and they blamed my pipes and clamps.I tried using t bolt clamps,3/4 inch thick RRE clamps, and good coupler material from amazon with no fix in site(it was blowing at the intercooler inlet not the pipe).I ended up having better success with a used stock srt4 core which never blew off even at 27+psi.
