If you had 10k-14k

the 530 and 535 dont have very different stats, but when it comes to tuning i cant help thinking that being bi-turbo will lend sooo much more tuning capability. In particular, i'd like to run nos too, to try and reach 400bhp. The only issue i can see, even with a twin turbo, are the huge torque spikes that are gonna really make that clutch work for its money... being a tdi is hard enough on the clutch without adding nos to the equation, even added progressively. so yeah, in short, bi-turno i'm hoping can give the same or more power, but wit less clutch strain. God only knows what it might cost for a 400bhp clutch for a 5 series bmw!

Agreed. Of course the same block is used in both the 330/530 and 335/535. The "30" has a Single turbo (Big one), and the "35" has a Two Turbo's! (Small one and a BIG one)

They both have the same displacement, same driveshafts, same steering racks, same wishbones, same balljoints. Infact, everything is identical, except two Turbo's, a different ECU and some additional pipework.

I can't help but think the "35" is also the only way to go with a BMW diesel in terms of tuning.

They stuck 2 massive T3 Turbo's on the BMW 5.0 M5 which took it from 507BHP to ~850BHP IIRC? Both the SMG transmission and the clutch remained standard and could cope with the 40% power increase without any issues. Apparently, it was a dog to drive though. Turbo-lag galore because the Two massive T3's were stuck at the rear of the car for two reasons - Heat and Heat.

i think we should probably be having this conversation here or in your diesel tuning thread, lol
sorry for the OT guys...
