Hi

other mods you may want to look at for handelling are strut braces. These will stop any chassis flex between the towers.

Performance wise? - well you could get a supercharger kit for your engine, but tbh this will reallistically only get you to around 200bhp, and will cost around £4k all in I would think.

If you did a BEAMS blacktop conversion however, the block, gearbox and ecu can probably be picker up for around £1100. You would also need the subframe as the Altezza has different mounting points to take the beams so you would bneed an altezza subframe or pay for some custom mounts welding in.

Apart from that Im pretty sure you prop shaft and diff will be fine. So prob four around £1500 all in you could get 200-210 bhp

HTH

Cheers

charger approx £2000 a noise you will never forget...dont know were this 4k is coming from??if your handy with a spanner you can fit the charger in just over 2 hours i did outside my house...

dont bother with the beams conversion too much greef and cost (well over the £1500) ie wiring issues etc if it wasn't greef we'd have all done this insead of supercharging/turboing our is200.

just sell the 200 and buy the altezza that would be far easyer..

strut braces wont really do much unless you are running a silly hard suspension and have braced up the lower suspension..the is's strut tops dont really flex much..

Is that £2000 for a 'supercharger kit' with intercooler etc. or just for the charger itself? Do you know where the best place to source one from would be? As I may be looking at getting one during the summer. :)

Also look at uprated ARB's to sharpen up the handling, probably one of the more forgotten handling mods.
