You will need internal work to get that kind of hp so your question about re-building it is moot.

Bad? What is "bad"? Gears in the motor?

Very unwise with the stock compression to run that turbo setup. The N/A M motors have high compression and love to rev out.

The valvetrain, bottom end, and electronics are not setup for a 50% increase in power.


When turbo charging motors that are non rebuilt high mileage stock motors it's safe to say you shouldn't run too much boost. A garret 35 R is a great turbo but its overkill for stock applications.

My suggestions, save up your hard earned money and do it right the first time ; ).

You ll not need a chip or map the unit it ll work mechanical if you turn up the fule pressure! up till 3 bar if u have 400 cc ingectors. around 0,8 bar at the turbo. When u install the bigger uingectors u need 2 dissconnect the battery and then when u start the engine let it map itself on idel and repeat that moment 5 times!

Rubin is correct with the compression a thick MLS gasket sault that problem.

Stock is 10.2:1 New comp 8.756:1

( 3.5-1.8 )*(84/2)^2*pi = 9421mm^3
465509 + 9421 +50599 / ( 9421 + 50599) = 8.756:1

Also Need new Bolts ARP From the us hehe good things!

With this settings u can go up to 1-1.2 Bar 0,8 daily driving! we were driving 80000Km with my old engine on 0,8bar boost!

If you need some help dont forget 2 ask!
