Posted for a mate who dont have the t`internet.
He's got a corsa sport, dont know the engine code but its a 1.6 ecotec engine (think its the same as a corsa gsi)
He want more power out of it and would like to know what to do to acheive it. around the 2k mark as a budget but throttle bodies or twin carbs he's already said he doesnt want (for some strange reason)
Thanx guys for any info
