There is a firm in Ortenburg Germany that will tune the IS200 to either 180bhp (stage 1) or 200bhp (stage 2). This is done through porting of the engine, modifying intake and exhaust, etc, etc. No turbo, no supercharger.
Stage 1 costs about 1500 EURO and stage 2 3000 EURO + 16% VAT and 20 EURO / hour in work fee.
Se attached price list that they sent me. It's in German but you can you can figure it out in general. Give them a call if you are interested !
Oh look at the spoiler kit (pictures below in the .pdf file) they offer with double sports-silencers. For 1300 EURO. Is it rad or what !
The same 200 bhp through normal aspiration, must be an altogether different feel !! And 1/2 price to the kompressor !
What do you think...
