Ok basicly i have a stock turbo(s4) i plan in the future to go to a bnr turbo dont kno what stage yet maybe a 3??? well my car pulls hard untill i boost it for a while like doing multiple runs and im guessing it gets heat soaked real bad cause it gets slower and slower untill you let it cool completely off then it returns to normal, what fmic core can i get from ebay or w/e that will work good for my application what size, size pipes, i want it to fit right also????? i kno that are alot of cores on ebay which ones work decent

thanx

 

oh man, please dont but ebay ****. its such.....well ****. why do you think its so cheap. get ebay piping if you want to save some money. but get a name brand intercooler. atleast you know you are upgrading properly. and not just spending money on a cheap as FMIC that could be worse.

 

there is an ebay pipe kit with rolled ends on the piping, 4 ply silicon couplers and t bolt clamps. if you have a stock s4 engine i would recommend a stage 1 or 2. i have a s5 with large streetport and a stage 2 and i dont get full boost (15psi) until 4300rpms. look in the dyno/timeslip section. i made a thread about bnr turbos and some people with similar setups to yours have posted dyno charts.

 

so no one has ever gotten a decent core off ebay? if so please speak up cause there are so many on there i have no idea what size i need or design or anything, ive been reading on here but i just dont have the cash to drop on a 1000 intercooler...

what about these

thanx
