View Full Version : Bolt-on performance for V6

03-24-2009, 10:22 PM
Just curious if anyone has had good (or bad) results with any bolt-on performance mods for the 3.0L V6 found in Pathfinders (I think it's called the V30)? I'm going to be doing a SAS to my '90 'Finder and it will likely require headers. I've heard that headers alone make very little difference to this engine, not that headers make a massive difference to most stock engines, but supposedly it's almost unnoticeable on 'Finders. Blah, blah anyway, I'm looking to compliment the enevitable headers.
Also I know that I can do a cold air, injectors and the rest... it's actual experiences I'm curious about, not progected results.

Best bolt on performance for a V6 is a V8 :D

is it TBI or MPFI?

this makes a difference. in 90, they had both.

If its TBI the only thing you can really do is headers. cam, ecu.. but its VERY expensive.

There is a little more availabilty if its a MPFI.

the designations are VG30i for TBI
VG30E for MPFI.

I've heard of adding a supercharger from a newer xterra ever know anyone who's done that?

ya, you can do that. But its not that easy. and with a high milage engine like yours, it won' last long. and i believe that you would have to do a stand alone fuel system. something like mega-squirt.

Bolt in a Toyota engine....

Ya, I didn't think it would be very realistic, more curious than anything. I wish there was an easy way to squeeze a few more horses out of her, she's a bit of a tired ol' dog! I wonder if there's anything to be gained by pulling the CAT? Maybe I should just plumb the exhaust straight in to the intake with a flex hose - that would be kinda like a supercharger right? Kidding, just kidding.

If I was gonna use a Toy engine I'd just use the whole Toy! I'm actually a big fan of Tota. After some research, I've found that the VG30i is a very popular engine with the street crowd and even in some forms of racing, so there's got to be hope!

they have potential to be very powerful. but its not cheap. Oh, and don't worry about it being week. look at my rig.. 345K on it
