Hello and welcome to the forum. There are a few people on here that have swapped engines into thier Ti's. But mostly they swap a m50 or m52. I don't know if anyone has done a m54. You can look around the swap section and try to find some information. And there is a member on here by the name of J!M and he sells a swap manual and electrical guide if I am not mistaken. Here are some links. http://www.318ti.org/forum/showthread.php?t=25713 http://www.318ti.org/forum/showthread.php?t=12912 I don't know if any of this will help you with a m54 swap but good luck to you. __________________ custom dual exhaust,M3 front and rear bumper, 10.4 inch roof mount drop screen, Viper alarm system, DSII's rims, M3 Vader Seats, M3 Mirrors, Carbon Fiber CAI, Smoked Corners, Side Markers, Leatherz armrests, black grilles 225k miles and still the Ti goes on |
