Surely a turbo, although more expensive, will be making power much lower = more fun!No cos the 2.2 gives its extra power right from the off cos every revolution from idle to red line has that 10% more air/fuel mix to set fire to. Thats why some of them (esp on the 92mm crank) make such massive torque low down that kinda helps balance out the losses from the cams.

What about balancing everything, the fact that you'll want a custom set of cams for the 2.1, the sundry irked like bearings, the injectors, the mapping etc etc etc.
Yes Ed, We're all aware that mild (mild enough to run on hydraulic lifters) cams run happily on the standard ECU as there are many people out there running them.
Im not gonna factor in the cost of balancing everything as the turbo engine for comparison wont of been balanced although this is something Im gonna do to mine as it dosent cost a huge amount (compared to some machining)
You dont need custom cams for the 2.1/2.2
I didnt factor in the cost of bearings again cos this is something that the turbo comparison wont have and also some tight f*ckers on here re use bearings.
From what Ive read the standard GTi6 management will cope with a 2.2 conversion as all the data is within sensor ranges and the standard injectors can feed it enough fuel.
At the end of the day give me a few months and Ill hopefully have my 2.2 built up and be able to prove the point.
