No recognition for euro tuner cars?

:--(

M103's are good for 230-250
Non amg m104's are good for 300 with a very good dyno tune

You would destroy your bearings in a matter of tens of miles as the stock oil system is shit, you would need extensive oil cooling; rods would bend after 350hp, cranks good for that, pistons and rings are good for 300

Stock cooling is fucking shit so youd need a better rad/higher cfm fans

Stock ports flow like a straw

Stock c/r is too high for that much boost to hit 600

Auto trans is cock
5spd would need a full build and a very good clutch to handle over 400ft/lbs

You would need a custom driveshaft to not bend like rubber for 600 crank

Assuming you could actually use this power without spinning, you'd need much wider tires/wheels

Source: 2 190e 2.6's and 3 300e's
My option is either a 3800 s/c swapped Porsche 944, easy to drop to a 2.8"-2.6" pulley with the stock rotating assembly with meth injection and an intercooler. Tune + 600cc injectors would bring an easy 350+ crank and the stock transaxle is good for 500 crank at least.
Dump 2g's on a swap, another g on rims/fat tyres, and 2g on supporting mods for the pulley swap+tune.

>If you have the M103 or M104 (280,300,320) engine and it is in good condition , it can handle easy up to 600 hp without having to change anything in the engine.


They also say the stock pistons are good for 1200hp.

Oil cooling is also a bolt on.
