Hi
Have you driven/owned a modified sx? I'm in a similar position to the op, I've got a stage 3a s14a and I'm considering selling up for a Z, would be nice to get a idea of the straight line performance difference...
Blimey, I know everyone here
Straight line a 3a 200 will dick all over a Z33, TBH anything over 1a is going to beat it. The power delivery is a lot more exciting in the 200, you dont get the thump in the back you do with a big turbot.
However, IMO the Zed is more rewarding to drive and generally a nieer place to be, and having done a couple of SXOC trackdays the real life difference isnt that great - sure, the 350/400hp guys pull away a bit on the straights but they are letting me past after the next corner, a Z33 is a lot easier to drive on the limit than a 200 is
Its also rather awesome as an out of the box drifter, bear that in mind when budgeting a years worth of tyres
