TIA Thewiseguy 07-20-2007, 08:12 AM Does the oil pump nut problem affect the Euro engines too? TIA no esp. not the 3.2 JamesM3M5 07-20-2007, 08:52 AM You can break the keyway for the secondary oil scavenging pump, but the nut itself does not back off. The crank is designed to sustain higher revs, which is what typically causes oil pump nut and oil pump shaft issues. morerevsm3 07-20-2007, 09:13 AM only oiling problem I have heard of is starvation on S50B30 on long constant radius high speed corners on sticky tyres, no oil pump nut or valve retainer issues like US version calypsoSA 07-20-2007, 02:00 PM Damn the americans really did get shafted in the ass. Thewiseguy 07-20-2007, 02:18 PM Damn the americans really did get shafted in the ass. no we didnt, we have the beauty of the shipping industry. I put the motor in my car. rennen5 08-09-2007, 12:47 AM plus we can utilize our lighter drivetrain components along with the Euro powerplants and this really makes our cars faster than the euro counterparts. Correct? morerevsm3 08-09-2007, 12:08 PM plus we can utilize our lighter drivetrain components along with the Euro powerplants and this really makes our cars faster than the euro counterparts.

Are you speaking of the Euro 3.2's heavier diff? US spec 3.2 cars had weight savings in their headlights, 5 speeds and medium case diff over the 3.2 euro counterparts... but euro 3.2's have an edge in alum doors on occasion, and better rear axles later on. Off hand, I can't think of any other major weight differences. I think it is fair to say that if you started with a US (euro 3.2 engined) M3 and put on alum doors, retained the 5 speed, upgraded to a 3.23 diff in medium case that it would be lighter, and geared the same as a heavier euro car, therefore faster. But, this is a silly game. If you take a stock 3.2 euro car, swap diff to 3.91, leave in the 6 speed and better headlights, you'd blow away the "converted" US car, see where you were going at night, and still get decent mileage and a diff that would last for a long time. |
