I was wondering if there is a surcharges or turbo for the 03 pathfinder or any way to increase my HP and torque ....maybe a performance chip or something ..

Re: Supercharger
That just says supercharged I doubt ur really is
Re: Supercharger
There isn't a market for turbo'd or supercharged R50 pathfinders man. the majority of owners are not concerned about power, they just wanted a reliable SUV that will get their kids to school safe. out of all the thousands of pathfinders sold in the states, theres what, 100 owners here on this forum, and maybe 5 people want 300+ hp from them? finding a company that offers high performance parts for our trucks is a long shot at best.
If all you want is an SUV that goes fast, Porsche, BMW, and Range Rover all make SUV's that will blow the doors off many sports cars. If your pathfinder holds a sentimental value, or you are trying to go for bragging rights, then all I can say is anything can be done. here's what you'll need.
complete tear down of your stock engine:
- replace rods with stronger custom made ones
- replace pistons with lower compression pistons (will have to be custom made, unless 350Z low comp pistons from JE would work..don't know its never been tried)
- build the fuel system up for boost
- find someone to make you a metal head gasket, or O-ring your head and block.
- machine better valves, guides, and find better valve springs that match the stock sizes, but have a higher rate to compensate for a pressurized engine.
- rebuild the engine.
Next, find someone who can Tig weld...preferably someone with plenty of experience building high HP engines.
- build tubular manifolds
- select turbos, a pair of GT28s would do the trick, and the rest of the turbo parts (wastegate, and piping)
- Intercooler? I wouldn't think about running without one..so you'll need one of them also, and all the piping to go with it..don't forget the BOV
at this point you will have a built engine that can handle the boost, and have the complete turbo system installed....but nothing to control it. The stock computer won't do, and there isn't any flashes out there for our ECU for boost, so Its standalone time! depending on where you live, it might have to retain the stock ECU to stay OBD-II compliant. That means custom engine harness.
Next would come tuning of the new computer, and dyno time.
after all this, no one knows if the stock transmission would hold up to all the new torque? lets just say it does up to 350hp...thats only 40% more then what its doing with a stock engine. So not a ton more, but it will wear out 40% faster.
still need a boost controler, and a boost gauge too, don't forget about addressing any possible cooling issues since the engine will now be under pressure, producing more heat. so the stock radiator would most likely need to be replaced with something more up for the duty.
At this point, it would be fair to say you'd have a reliable running 350hp pathfinder...and about $25,000 to 35,000 in the hole if you paid retail for everything. If you have the hook up with some of the parts, maybe you could save yourself $3000-$7000?

I've been building cars for 15 years plus, have connections to Super GT series race engineers, Indy league teams, CEO's to some big tunning companies, and all my experience tells me, your money would be better spent on a Porsche Cayenne my friend. Something that was built with the intention to have that much power and be used everyday. you would basically have to re-engineer the pathfinder from the ground up since no one has ever ventured into making what your asking. But if you are willing, and have the finances my friend, anything is possible, and I'd be glad to lend my knowledge to help you reach your goal.
