Re: Upgrading a 164...?
About Intake runners it is true you can win 20HP (16HP to be honest) only on 24V engines, however it is over 4500RPM and it is NO big torque improvements... I have it ...
Im going to turbocharge my alfa and put a self engine management, it will give me 320-350 HP for a 8K dollars. Here in Argentina I could not find ANYTHING with 320HP for 16K dollars (8K from car + 8K from modifications)
Here is a detail
Engine management : Megasquirt 600 dollars
Turbocharge : Garret GT3071 = 1000 dollars
New forget pistons: 1200 dollars
Exaust modifications: 600 dollars
Engine rectification: 1200 dollars
Intercooler: 500 dollars (water cooler)
Tuning and instalation: 2000
I will post the advances on it, at this moment I'm trying to put the new engine management on standard engine. Standar engine has 224HP (150K km, headers, intake runners and some self tuning AFM)
