Agreed, driving style should dictate the engine size to begin with. Will be be only for drags? Maybe a track day? 207 will rev harder and handle higher pounds of boost but the 2.5 will be a total torque machine in comparrison to the 207 2ltr.

Yes 1.8bar through a 205 will go no problems, but like atz said, it wont handle it for long. Most likley do a big end.

I think its personal prefrence but for me id say 2.5ltr for track and 2ltr for drags. Obviously both engines can do both applications but you have to wonder why people go for a 2.2ltr strokers when running 1/4 miles.
