i need throttlen

[Wraith]

b&b custom, I think you got a bit to much faith in a 2.2l astra, I mean you
can get them fairly quick But getting that thing to 13sec you'll need to
stick a Turbo on it, and not the small k4 something bigger..

OR a NOS kit, will definitely do that for you

Will have to eventually do some upgrading to engine internals to restore longevity, but that would be the easiest/cheapest way of getting an N/A 2.2 Astra into the 13's......
