Will a Supercharger or Turbo shorten the lifespan of an engine? Has there been any testing done? I am talking about the overall lifespan, if everything was to work properly, not if something is blown because of the forced induction. I was told that a SC or a Turbo, added to a N/A car, will cause problems down the road and may cause the engine to wear much faster and consequently ruin the engine in a much shorter time than if you had left the engine N/A. Is this true? If so, what can be done to prevent it? Thanks.

Engine life is directly porportional to how the said engine is maintained and operated.

But then again, someone that beats the hell out of the na motor and never changes the oil might last as long as someone that runs a SC on low boost and takes care of it.

You cannot say one or the other as the biggest unknown factor is onwer care.

Well, I would like to know if 2 "gearheads" ran and maintained their engines as best they could, one Turbo/SC, one N/A, could one draw a direct corollary to the SC/Turbo engine failing faster than an N/A engine?

Nope. Because there would be the variable of the two engines. No two engines are alike. Even with similar miles/year. One could be more prone to damage if boosted or na. If one could pin it down, the example would be so specific, it wouldn't have any revelance to your question as those same conditions are too unique.

in general though, forced induction creates more stress on the engine. this could lead to a shorter life. i'd be more worried about a tranny than the engine though with a blower

no way to tell. Over all theres way too many conditions to factor in. Now one might say that the boosted car might face more ABUSE due to full throttle runs etc... causing the motor to wear down faster.

I think the answer to his question is... "there are people who've had an aftermarket SC/turbo for 50k miles and nothing has gone wrong."

But then again, there are some who've blown N/A engines before 50k miles.... it all depends how you treat it.

In general I agree. Don't do the crime if you can do the time......

If he's asking if you can do things to get a boosted engine as reliable as a na one, there isn't. Not without spending another $4000 or so.

LithiuMax

Jeff, that was implied in there somewhere, heh.

What would another $4000 get me?

Built motor and maybe standalone electronics. And maybe someone to weld your wastegate to 10psi.

LithiuMax

I see. Well, if a SC or Turbo ever come out for the 2K2/2K3, and I have enough money laying around to throw down on one, I'll do it after the 5/60 powertrain warranty is up.

There are plenty of them out there...you just have to make them fit your particular application. Anyone who can build T/C systems "could" do one for a VQ35 5th Gen...but who's going to be the one to do it? I've already got plans on T/C'ing mine, but I'm waiting until the 36K B/B warranty is up (and using the time to research the stuff I'm planning on getting).

LithiuMax

I had no idea.. sweet. Well then I can start saving, since now I know there is a chance that someone will make forced induction possible on the later 5th gens. Thanks for the heads up..

It depends on how you drive it. First, Maxima is not designed for force induction applications and their parts are tested only up to handle a certain amount of power. Second, any major modification like SC/TC will make your car less reliable. It's not plug and play. Even with the Stillen SC kit, people still ran into problems. It will need more time on repair and maintenance.

I will recommend oil cooler, tranny cooler, aftercoolers and water injection.

F.I. cars produce more heat and the charging air temp raises 10 degree F for every 1 psi of boost. It would be nice to have something to cool your car.
