Go and troll elsewhere Ed. I was trying to be serious/helpful.
You forget that I have done alot of the mechanical things here that others just talk about and not only that but studied engineering and have worked for Honda and a company building custom trackday/race motorbikes in my time.
Ok Mr. Honda Engineer.
Lets talk about area under the torque/rpm graph.
Let us for a minute dwell upon the differences between the application of a turbocharger vs n/a tuning.
A low-boost turbocharged '6 with the correct compressor will eat your 2.1 for beakfast. On a race track you will probably find it a little closer, but the reality of driving a highly tuned n/a on the road is that it will be very lumpy and you'll be waiting a long time to get on-cam. By comparison the turbo will up and go. The mid-range punch will far outstrip your car out of lower speed corners, something which will be exacerbated by the 6speed box. Unless you modify the final drive or run a 1.6gti box.
Either way, bang for buck, a turbocharged rs engine will be far more flexible day to day, and far more of a weapon on the roads than a 2.1. Though the 2.1 will sound pornographic in the process of being beaten...
And there is no way a 2.1 will cost you significantly less. and be less temperamental. and probably more fun to drive more of the time.
Ive had a good hunt through google images for a 200sx power graph thats not either completely bog standard or 350bhp+ and seem to fail miserably so cant do a comparison but heres the graph from Matt-Rallye on the GTi6 forum of his cammed 2.1

2.2 isnt expensive, Ive paid sub £30 for my block, and ill have a 2.1Td and S16 rods for less than £60, £400 for some 88mm pistons and thats £500 plus a little bit of machining then for the head Ive seen second hand cams on the GTi6 forum go for about £200 and the whole set up will run on standard management.
so maybe £1000 all in.
