01silvapathy Posted December 24, 2011 Share Posted December 24, 2011 You are my hero! Im definitely going to need more info on this such as parts used and how everything is setup. A driving video would be sick also! Link to comment Share on other sites More sharing options...

A driving video would be sick also! Well the parts list inlcudes a Tial BOV, Tial Intercooler, the turbo is cheap and for the turbo to work properly and FMU was added for it to deliver more fuel with a fuel pressure regulator and walbro fuel pump and other stuff. exhaust is 3" all the way no cats or resonators and if I am not mistaken the muffler is a dynomax. I am working on brakes and then I would be adding a Haltech. The driving video, I will try to find someone to video it since I am a lone driver Link to comment Share on other sites More sharing options...
Tungsten Posted December 25, 2011 Share Posted December 25, 2011 FYI: That engine will go explode if you put as much as 10 PSI into the block. I would not go over 8 PSI just for safety. You will have to completely rebuild the motor with lower compression pistons if you want to boost it above that. Also, stock VQ engines are known to blow up when boosted without a proper tune, even at a low PSI setting. 1 Link to comment Share on other sites More sharing options...

Yeah i know, im getting a Haltech ASAP and later some pistons, plus do you know if the tranny can handle the horsepower? Link to comment Share on other sites More sharing options...
Tungsten Posted December 25, 2011 Share Posted December 25, 2011 If you are using the automatic, I don't think it will handle anything over 270-ish HP. You will notice it when the transmission starts to slip. If you are using a manual you should be good until 500 HP or so. Link to comment Share on other sites More sharing options...
Alfredo24PR Posted December 25, 2011 Author Share Posted December 25, 2011 The transmission slips from 2nd to 3rd when im at full throttle when the dyno shows a peak of 304 HP at the end of second gear. Any idea how to fix that transmission slip, besides lowering boost? Link to comment Share on other sites More sharing options...
WOT Posted December 25, 2011 Share Posted December 25, 2011 Id love to see how the manifold was made and actually fit, do you know much about the install or did your mechanic do most?? I put a 50 shot on my VQ a while back and the auto trans HATED it and slipped bad everytime, I cant see your tranny if its oem holding that power for long at all. Would love to see some street pulls!! Congrats Link to comment Share on other sites More sharing options...
01silvapathy Posted December 25, 2011 Share Posted December 25, 2011 Looks like a shift over to a standard trans is next lol Link to comment Share on other sites More sharing options...
Tungsten Posted December 25, 2011 Share Posted December 25, 2011 Lower the boost or definitely change to manual. The automatic is already as beefed up as it can be. It's the heavy duty version of the WD21 transmission. 1 Link to comment Share on other sites More sharing options...

Would love to see some street pulls!! Congrats My mechanic did all the work lol, he made the manifold and every custom work. I will shoot a video so you can see what is visible of the work that was done. I will try to post some street pulls, when I have a passenger with me that can video it The tranny well I guess switching to manual is an option or reenforcing the auto but i will talk to my mechanic and see what he tells me.

01silvapathy Posted December 25, 2011 Share Posted December 25, 2011 I know nothing about the pathy's manual trans....was it pathfinder specific or a common part that was used between a few different nissan models? Link to comment Share on other sites More sharing options...
Towncivilian Posted December 25, 2011 Share Posted December 25, 2011 The manual transmission for the R50 is the FS5R30A, which was also used in WD21s. Manual trans Pathfinders do not have the power valve screws. Other than that, I don't know of any significant differences. 1 Link to comment Share on other sites More sharing options...

WOT Posted December 26, 2011 Share Posted December 26, 2011 The tranny isnt even the weak point in my mind, the block in my eyes is a ticking time bomb with that much boost and an FMU for tuning Still no close up pictures?? Under the hood, your turbo is way up and off to the side with the compressor side outlet facing in an interesting outward direction Im curious how the piping was done there Getting that manifold fabricated must have been tiiiiiiiight, I quiver at the thought of even removing my manifolds on the VQ Link to comment Share on other sites More sharing options...
Kingman Posted December 26, 2011 Share Posted December 26, 2011 Very nice. If you want to keep it automatic it'll need a newer RE4 from a supercharged Xterra or Frontier. They will handle the power and not grenade like the one that's in there now will. Link to comment Share on other sites More sharing options...

You think Nissan would put a standard RE4 with a VQ? I doubt it. Link to comment Share on other sites More sharing options...
