First I've bought a log style turbo manifold for the 2.2 ecotec, from ebay. I've found a T4 turbo with a 104 exhaust trim, but my suggestion for that setup, buy a ball bearing turbo, got many **** with my no ball bearings turbo.
I've build my entire charge pipe with 2.5'' Galvanized steel, 3'' for the air intake and the exhaust downpipe...

-Turbo manifold-----------------150$
-T4-------------------------------500$
-Piping 2.5 and 3''--------------200$
-Used tial wastegate 38mm----150$
-Used turbosmart Bov----------100$
-Hardware(fitting,hose)--------75$


8h to build the setup, 4h to tune.....Enjoy


Only one advice, I have a adjustable fuel pressure regulator, my 650cc injector at 28 psi have approx 68psi of fuel pressure, far from stock pressure

75% injector duty cycle at full boost!

 

sorry double post!

 

now the only big question is how hard is it to tune...since this was one of the big reasons y people didnt want to do this...

 

ill make it simple and just qoute my own post...


build it and ditch that s/c youll be way better off.

 

Let people decide how they want to build their car.

Not everyone has 5K for a Hahn Stage 5 kit.

 

I'm looking into doing this as well. I have everything I need from a turbo kit form my last car.
Only thing I'm unsure about is what to use to ensure the SC bypass valve opens at a certain boost so that it's just the turbo working.

 

Its in the tune. There are two boost reduction tables. One for 1st gear and one for all other gears. The table starts at 4000rpms. Set the tables to 95, 50, 25, 0, 0, 0, etc

 

sub'd for later... Bad Ass!

 

I think im going to do this to my ss. Im pretty stuck on zzp's kit.
I wonder how it will perform on the autobahn
Im going to germany next week

 

Since they bumped it I wonder what happened with op car?

 

Probably no longer with us ^^^ haha

 

So im thinking of getting a tvs or maybe the m90 supercharger if zzp gets it right to be installed, then eventually go twincharged with of course a bigger turbo.

 

nice balt any vids?
