What sort of modification needed to make 320i sound like this?

[DFL 0]

I think that was well above 8000rpm

I am thinking schrick cams, solid lifters, upgrade heads, chipping?

You can buy it in the UK.

The 320si is a special homologation version, built in order to qualify the car for the FIA World Touring Car Championship (WTCC). Released in 2006 and limited to 2,600 units, 500 units being sold in the UK. The 320si uses a modified 4 cylinder engine (N45) different to that in the standard 320i (N46).

Modifications include an increased redline to 7,300 rpm, a shortened stroke (by 2 mm), an increased bore (1 mm) and higher compression ratio (11,0:1) over that of the standard 320i engine.

The engine is mostly hand built and does not have Valvetronic, decreasing the number of moving parts. Acceleration from 0 to 62mph is in 8.1 seconds and acceleration in fouth gear from 50 to 75mph is in 7.7 seconds compared with a standard 320i which achieves 9.0 and 9.1 seconds respectively. Fourth gear acceleration is comparable to that of the 325i which achieves the 50 to 75mph sprint in 7.5 seconds.

Nah the one I posted is actually E46 I6 320i racecar. Not the current E90 I4 WTCC car.

I6 sounds way better than I4 in my opinion.

Is it difficlut to get a M52TU 320i to rev over 8000rpm? I mean only increase the rev without reaching that kind of hp is fine too.
