well finally i convinced the owner to move his bu&& and go to the mechanic today right now their takin off the bumper , intercooler,oil coolers to reach the stock the radiator since its a once pieace part not like the CSF radiator it comes in 2 pieces , i told the mechanic to make sure abt the pressure to be maximum of 275 of the high pressure and 37 for the low , and their is a sticker on the bumper that tells u how much ferion u should add , but anyway how much ferion do u usually add then ? if we cut the black grill in the stock bumper can we move the oil coolers and put them next to each other in front of the empty space ? i doubt we can do that because we will block alot of air hitting the intercooler and radiator and stuff so we will have the same problems so i guess unless we go for the stillen fascia we leave the oil coolers the same way they positioned !?
