hi there, im dave and live in the uk,i own a astra j vxr 2014 which has the a20nft ,hoping to tune the car to around 400hp , its currently running 294whp in the stock k04.






dyno graph shows the before and after on the same dyno,car made just above stock figures

 

welcome and i like that. wish we had it over here

 

Welcome.

 

welcome

David, that looks like a fun ride, very clean mate

 

Thanks guys . Yeah it's a very nice drive. The drexler diff is excellent at putting the power down. Do you guys run lsd's in the f40 box?

 

Only once did I see someone had an LSD F40 and don't remember who. What transmission is in there? ZZP can probably hook you up with the turbo you need, the new ZFR based on the EFR 7163 would easily do that. Assuming you already have supporting mods then just get a good tune. If you pick up HP Tuners I'm sure someone in the cobalt world could remote tune you. Is that a real LSD in the car?

Envious you can get that, they need to bring it to the US.

 

Scyth snake and cmiller ran f40 lsd

 

Welcome

 

yeah the diff is factory fitted and also has the hyperstrut suspension and electronic damping control as standard and brembo 4 pots and 355mm rotors . turbo wise im looking at the zfr 6758 and the stage 1 cams , tune it and see how it goes, car has full decat 3" exhaust,large fmic and enlarged boost pipes,full intake .



couple of vids to show you what its all about

 

that's pretty neat

 

Welcome to Cobalt land, Once you enter there's no escape
