Guys,

I just build W202 with M104 engine 3.2L plus Turbo and supercharge. All the engine are factory based.

But not I face problems with the car...first gear the engine run smooth, but after change 2nd gear the power drop (turbo lag maybe).

I'm looking for pistons for competitions set, maybe it can solved my problems here

Please drop me some advices how to solve my problem or where can I buy that stuff...

Thanks anyway

 

Thank you very much Mr. ForcedInduction for your advice...Last time we tested the car nite time, the power was very ok, but when the event held in midday with 39 degree Celcius the power drop.
