No mate, it would be cool, I would have, I just got tired of coilovers and an old car (mine was a '99 import) I wanted something more refined and fresher that I could still track and **** about in, so I spent my money on a 370Z.
The car is very well balanced from the off and being RWD it will cope with the extra 200hp+ much better than say a FWD car.
Also, the chassis on the S2000 is great, so again, it can handle the hike well, no point in bracing these things either, solid as, although I think under bracing is the only way to improve it as opposed to top mount, they just don't do anything to it.
These are proper cheap now, when/if you buy, try and get a GT version with the hardtop and make sure the geo bushes have been greased recently as its very common for them to seize and can be costly to sort out.
Let me know if you need any info come buy, I'll be able to help out man.
Now, on a similar but different route, my mate just imported a sweet as a nut OEM S15 (Silvia) now that's a crazy boost car.
Old school turbo RWD drift machine, stunning, crazy car .
Thanks for into mate really appriated. Something for me to look into
