turbo on each bank should do the trick.
I really wouldnt bother tuning the V6, I'd just leave it as it is, and spend youre money elsewhere, suspension decent brakes etc.
I have one as my daily, and they just seem lethargic to me.
MK i was thinking about a single turbo as it could be easier for space that trying the twin turbo route.
Paul, kinda what i thought, to much money needing spent for little power gain,
The X25XE is also the base for the DTM calibra's, so it's not an entirely useless lump, I'd bet most of the lethargic feel comes from a heavy fly and clutch combo?
no. they used the 3,.2 v6 from the monterey.......Quote:

the de-cat has made a difference, maybe a remap to suit the loss of the cat might help, also ditching air-con etc and full interior,
christ i dont even know what gearbox is in these lol my brother just told me he is giving me the job of track preping his car lol
mowgli MSD have done that already when the car was built,
ok, i didn't realise it was a special build...sorry...
lighten everything, its cheap.
the people who still play with the msd vectra challenge cars put 3.2 botton ends in.
"All DTM cars at this time used 2.5 ltr. V6 engines. (2.5. ltr was the max permitted by the rules)"Quote:

X25XE was the base engine, and the reason that the "Calibra DTM" is a 2.5.
