Thank you guys for your kind words. Construction e30 turbo cost me a lot of nerves and money. Swap had to perform the company M-Garage (, but it did so badly that my heart until it hurts. They - sorry - F*cked Up a lot of things!
While placing the head mounted on the curved suction valve 3 cylinder!
Now the car is already pre-tuned by Michal Malecki ( Turbo pumps are powerful 0.5 bar, and during testing we won with the Porsche 911 Carrera sprint 80-200 km/h ;)
There is still much to do, but more on that soon ...

ps: sorry for mistakes;)

Now that's the way to boost an E30!

I did consider this many moons ago, with my 1990 E30 325i M-Tech II Sport, but the cost was more than 3 times the value of the car back then, and there was no support for such a project.

Love this car!
