How much money do you want to throw at it? Start with the easy stuff. Decat pipe, give thick end of nothing on its own but supposedly allows turbo to spool faster (made no appreciable difference to mine) Blank EGR, may need one with the hole in it. Again no power on its own but stops the cack going into the inlet manifold Bigger intercooler, just a few BHP here but allows you to run higher boost. fiddly to fit but ok if you're competent on the spanners. Remap, live remap on the rollers to take advantage of the above stuff. That concludes the cheap (ish) stuff. That lot together may bag you about 165 - 180 BHP Want more power? now we enter deep pockets arena. custom built injectors to get more fuel in there, or apparently 2.2 injectors will fit, but you have to be careful as there are several variants Hybrid turbo, these have a bigger impellor to shift more air, again a 2.2 turbo will fit but the hybrid would be a better option. above may be of consideration if you happen to need injectors or turbo because of failure otherwise an expensive project. another custom remap to hang it all together Unlikely to get more than 200 bhp, i've not heard of any. Want more still? read about someone with Methanol injection pushing out some serious power on a 2.2 mondeo Suppose you could drop a 2.2 lump in there and then do all the above. Hope thats of interest for you G
