I couldn't get RAZ-0 to print my reply
which is:
I have read where people talk about wanting
rear spare tire add-ons, turbo, snorkels, lift kits, and diesel engines, all of which are non standard, and most of which would void their warranty. Why then haven't you recommended they buy a different car?
May I recommend you moderate some other forum?
Because those things don't involve engine control computers that don't exist and don't require an investment well into five figures on top of the purchase cost of a renegade to get everything but those non-existent parts.
Turbos are a standard option. Diesels aren't in the us. I've told those folks if they really want a diesel, they'll have to buy something else.
If your primary concern is pollution, buy a different car. There is simply no existing option that will make the renegade a pzev vehicle without essentially turning it into a rolling she'll.
You want a pzev small such get a forester. You want a pzev renegade with awd, literally the most likely option is to gut the chassis and fit the powertrain of that forester, and even then stability control would be wrong.
There just way too much system integration and software. Nobody is fixing that, unless you are going to do it.
Also, strictly speaking would pzev vs. stock save more emissions than tossing all that stuff produces in manufacturing. Probably not.
