ALFAGTV6.COM

Hello oder like we say " moin moin",
I'm a little bit between the modell transaxle and the others old Alfas, because my one Alfa is a Duetto with a transaxle engine and my other Alfa is a Alfa 6 or Alfa Sei.
I love Turbo engines and the settings around and this is the reasons I'm here.

My english is not very well and like my cars expandable...

there is actually inside nothing speciale...
stock piston, rods and crank
modified is the inlet, oulet, flywheel, clutch, C&B cams and oil jets for piston cooling.
further a stainlees steel exaust manifold and 3" exaust pipe with catalytic converter.
inlet manifold and plenum is made for 8 injectors.
4 injectors (198 ccm³) in original place and another 4 injectors (440cm³) in the plenum.
the compressions ratio is 8.5 and boost mostly between 0,8 Bar and 1,25 Bar.

btw. hamburg is a lovely city but mostly to cold and rainy not like australia. I envy you for the weather...

That is some nice machining..

Very nice inlet and exhaust manifold. They look to be designed for much more bhp...

I was wondering how you would fit an intercooler and i couldn't have thought of that curved intercooler. Very smart.

Und jetzt mal gummi machen damit...

wow marco great work!
i love intercooler, and if u paint black u will never be able to notice it
the turbo manifold is also good, gives me inspiration to finish making mine

very big intercooler...what boost you want to run?

this is depends, if my wife with me only less is possible and alone on the highway (Autobahn).......
I tune my Adaptronic Ecu now from ~ 0,8 Bar (12psi) aprox: 240 HP up to 1,25 Bar (18 psi) with 305 Hp.
In the future I will fix the setting up to ~ 1,6 Bar (24 psi) or a little bit more when the turbo can it deliver without to blow only hot air.
