First off, I am a complete noob, so forgive me anything stupid i say.
I recently got a S80 2.4 from 2000 (runs on petrol) and i would like it to have some more power. it used to belong to my dad and it used to have 170bhp, but the dealer once took out the oil and forgot to replace it, so we had a have a new engine fitted and we got the 140bhp version. now i was wondering if it is possible to install a turbo on this block or if there are other ways to spice it up a considerable bit. and does anybody know if chiptuning it would actually be worth what it would cost me? ive also thought about replacing the exhaust system, but i cant seem to find one for a volvo s80 and a sports airfilter just wont do the trick (which doesnt mean i would still like to install it, if only i would know how to)
and the very last thing i would like to know is if anyone knows a place to get volvo r serie rims for not too much money, cos i want to change my rims but would like to have original volvo rims on it and those just look best.
thanks

The only place you will find the R rims is ebay ... the model name of those rims is pegasus and you can expect to sell a kidney to be able to afford them... they look good but they are only 1 inch bigger than the biggest stock s80 rims (18 vs 17) so it really doesnt make that much of a differnce overall..
you may also get those tyres running on the wheel well if you switch the rims

If you dont mind me asking, what **** of a dealer did you go to to forget to replace the oil! Why did you get a smaller engine than the car came with, shouldnt they have been obligated to fix it to spec?
