Guys having picked up an N/A S2 Exige about a month ago on a bit of a whim, I am really enjoying it. The character is so different to the much heavier and powerful Porsches I am used to, most notably the engine on 2nd cam is fantastic, but as I feared the torque is a bit lacking low down.
I am going to test a supercharged car when I get some time as a comparison, but I love the one I bought and would rather not change. I won't be puttting on an after market supercharger, but wondered if there are any proven sensible engine upgrades such a good remap which can help the modest low down torque
Cheers

Just about the only thing you can do is an ECU reflash that will smooth out and lower the cam change point. Various people doing it for £250+VAT upwards. After that induction, manifold and exhaust combined with a "GT" reflash from Hangar 111 claim a bit more power but will be >£1500 to do on a standard car.
I've already gone the induction/exhaust route so will be going for the GT spec reflash in the new year some time. Other than forced induction of one sort or another there doesn;t seem to be a lot about for a N/A car. You can get different cams etc but all the gains seem very minimal for a lot of cash compared to strapping a SC on it.

I am going to drive an 'S' but don't favour an aftermarket. I had one on my 911 (993) from a well known Porsche tuner in Warrington and really didn't like it at all. Opinion is divided on this amongst Porsche folk - in fact its polarised!
If I like the 'S' that much I'll trade up, but wondered if anything else is worth it.
The idea of channig the map to bring the second cam in at 5K ish would be good, but I do like that step change!

The opinion on the Katana is, to my knowledge, so far undivided in being 100% poistive from those that have had it done. It may be worth looking on SELOC for more opinions and talking to Sinclaires who do the kit. You don't need me to tell you you'll be taking a double depreciation hit if you chop in the NA and then get an S. You'd probably see 1/2 the price of the Katana back if you sold it on. This is the route I'll be going at some point on my NA. I have the lowered cam point (Lotus version) and it comes in at 5750. You still get the kick but it's slightly more subtle and does make the car more drivable. If I like the 'S' that much I'll trade up, but wondered if anything else is worth it.

Yup, I had the same conversion on my last 993 and loved it... and am picking up a Exige S in a few days time...
If you love the 2nd cam screamer character then don't go for the S - it still spins round to 8200 rpm but doesn't feel anywhere near 'peaky'.
But like everyone says, there's not a lot more to be had out of the N/A Toyota lump without sacrificing reliability - after all, unlike the K series cars the Toyota engine is already pushing out more than 100 bhp/litre in standard trim. Getting a lot more than that whilst remaining a 'road' engine with adequate reliability is asking a hell of a lot...
Get a Katana fitted for a fraction of the cost of upgrading to an S240. There are hundreds of Katana conversions now in both the US and Europe. The Katana can be installed or removed in a day so its not like you have to keep it supercharged forever if you want to sell. It runs at 6.5 psi boost so its not like your putting a lot of strain on the engine. You'll get 160lb of torque and well over 250bhp which will outrun an Exige S or S240 anyday of the week. You'll also keep the car your attached to
