trying to get the most power out of my engine.

[defrag010]

hey guys.
i have two cars. one is a 90 tsi and its my daily driver getting a stock rebuild. my other car is a 91 gst that is getting mods. ive been planning what i want to do and ive decided that i want to fit 2g pistons on the rods, arp hardware, and a metal headgasket. ive done alot of research but i havent been able to find a solid answer on what the most power a shortblock like im buliding can make. all i can find are the stock 6 and 7 bolt power numbers. assuming i have perfect engine management and precise tuning, would my 2g/1g shortblock take 450wtq reliably?

Assuming it's built correctly and you don't do anything stupid with the tuning, yes. 450 hp is doable. IIRC that combo has gone up to about 525hp. Have fun!
