More power for the Wrangler ?

Hello, a half year ago I got a 1998 Wrangler 2.5L (118Ps) and love him. Nevertheless he is just a little too weak on his chest and I want to do something about it. Meanwhile I also have the money (about 3,000 can ́s cost + my craft work) That’s why I wanted to ask you what is feasible and useful and what is not: — a 4.0L swap (cost ? expenditure ?) — turbocharger/compressor (the ammies have fanned out a few kits … what engine u. TÜV will say ?) — Customize translation (Vmax Leidet) — Customize aluminium roll tipper lever (http://www.jeep-community.de/showthread.php?t=4955) — Stroker ? LG Nico
