Hi everyone I have a simple question... I'm going to modify a little bit my 911 (70 2.2 T) and I want some suggestions:


I don't want to do any swaps or anything alike I just want to gain some power and I think of two possibilities:


1--> 86 mm 10:5.1 pistons and 2.4/2.7 crank, Fidanza flywheel plus some work with the heads

2--> 84 mm 10:5.1 pistons fidanza flywheel and the work in the heads

I have that two options but I'm open to changes of a different way to gain power but as far as I've seen it's the most common way to modify an early 911 with 2.2 engine.

Plus I'm changing the Torsion bars and the anti-sway bars for a Tarret and ER.

Have you tried the Rennshift for a 901?

Hope you could advice me about it
