Yes he did setup the suspension system for the weight differance, he has AVO coilovers and they have been setup properly. Also he has fitted a carbon bonnet to help weight issues at the front and has a pretty heavy stereo system in the boot to help the weight in the rear (not my cup of tea big stereo systems, but its his car not mine!) Wharbone, you are right you could do these things to compansate for weight, although as i posted the H22a is better for drag but for street use i'd go B series,The reason being loosing the AC and the PS is not the best bet for a daily driver. Also its so much eaisier to fit a B series. All i'm saying is that for a daily driven street car, a B series engine would be the easier option and you can get more than sufficient power for the weight of the car and you'll struggle to get that power down anyways.
Both are a good swap, i personally prefer the B18c5 boosted, but each to their own.
Anyway good luck cvchtchbck92 on whatever you choose. ste
