impressive! Nice work!

impressive! Nice work!

thanks! my mechanic did all the work lol

[Chris.m]

Wow, thats basically the Holy Grail in terms of pathyfinder mods

Questions;

What else did you do in addition to the turbo?
I know very little about this sort of thing, but apparently people upgrade the fuel pump, alter the ecu....

Also, are you the same guy as PathPro2002?

yep, same guy lol just thought pathpro sounded stupid and made new account since my original one was banned..

In addition to the turbo, an FMU. I do not know what exactly is that lol but its just something added fore more fuel delivery and also a fuel pressure regulator and fuel pump.

It still does not have any ECU, but I will be installing a Haltech soon, but first Im working on better brakes.

[asoomal]

Wait...Nismo?

[CanuckQx4]

Im very impressed the car is boosted, but Im curious how, since its a single unit off to the side, is only 3 cylinders feeding the turbo??

An FMU is definetely not ideal for a good tune, but youre robably running low boost to keep this engine together anyways.

I would LOVE to see pictures...

I didn think our trans or rear end could take any sort of abuse

[wisehunter1]

wow very nice work man! I also remember seeing a video of a supercharged qx4 on youtube a while back.

lol its not nismo, just a joke..

All six cylinders are connected into the turbo. I do know FMU is not good enough, it is only for a while until I get a Haltech. Boost is set to about 10, but in dyno it showed [email protected] max boost and the air/fuel was great.

On the transmission, Im definitely not riding my path like if its a formula car, because I also think it cannot handle much abuse.

Installing the largest auxiliary transmission cooler you can afford (and preferably an in-line filter while you're at it) and installing it in-line with the stock cooler may be beneficial. Synthetic fluid in the transmission and differentials (75W-110 preferably given your climate; the only such fluid I know of is Amsoil) will also lower temperatures somewhat.

[miamiheat3332]

Thats sweet! Please post alot more pics of how it was installed and what parts you used, i was going to attempt this, this coming summer of 2012, but i see someone finally did it. Definetly more pics on how its all installed and give us a 0-60 time!!! and also do a 40-80mph roll. Im probably going to jump on doing this , this coming summer for sure now.

[iceman14n]

This is amazing... I AM IMPRESSED.. MOST LIKELY GONNA DO IT THIS YEAR

[01silvapathy]

From what he was posting over on NPORA, his trans is slipping pretty bad with the added power. Looks like a standard transmission might be the only way to go for this kinda mod.

Thanks for the big tip, I would really need to try that and see if my transmission can keep up with the horsepower, but I think a manual transmission is the best thing to do...

I will take some closer pictures of the work to post here and will try to get the 0-60 and 40-80 roll when I have a passenger that can shoot the video.

as silvapathy said, the trany slips from 2nd to 3rd ONLY when driven at full throttle, and other than that when driven aggresively and then making a full stop the car turns off, since it does not have a piggyback or standalone yet, but the only real problem is the transmission slipping.

BTW, at 7 lbs of boost, the transmission did not slip at all and produced 263HP

I too think that a manual will be the best option in the long run. The auto trans probably just can't handle that much power, fluid temperature may not be the issue. You can get an infrared thermometer and try measuring the transmission pan and cooler line temperatures, but that isn't the best representation of the fluid's temperature. If you have a 4x4, there is a fluid temperature sensor in the transmission pan, and you can probe a couple terminals on the TCM's harness to get its current voltage after driving hard and then convert it to temperature in degrees based on a chart in the factory service manual. If you'd like to try that, let me know and I'll find the pins to probe.

A shift kit for the auto trans might help too, I'm not sure. A performance shift kit may require removing the transmission to properly install, ask your mechanic about it.

If you get an auto trans cooler but do a manual swap later, you can always re-use the trans cooler & filter in your power steering if you have no other vehicle to use it on.

I have the 4x2 and I will talk to my mechanic when he gets back from vacation next week and let you know what he recommends

[Towncivilian]

Okay. I'm fairly sure that the 4x2 does not have the fluid temperature sensor (I still need to confirm that by probing the terminals on my Pathfinder), so you'll need an infrared thermometer or install a fluid temperature gauge if you're curious about the fluid temperature.

Merry Christmas (if you celebrate), by the way!

Ok, thanks for the info. Merry Christmas to you too!

I have a couple of questions regarding your turbo

1.Why is it mounted where your airbox was?

2.Are you using high heat resistant plastic hoses to feed the exhaust into the turbo because those blue hoses leading into there sure don't look like they would be able to handle exhaust heat?

3.Where is the second turbo or are you only running 1 for now?

[Alfredo24.pr]

I have a couple of questions regarding your "turbo"

1.Why is it mounted where your airbox was?

2.Are you using high heat resistant plastic hoses to feed the exhaust into the "turbocharger" because those blue hoses leading into there sure don't look like they would be able to handle exhaust heat?

3.Where is the second "turbo" or are you only running 1 for now?

1. I really do not know, mechanic's choice, but I think it fits good and is pretty similar to a 350z single turbo mount.

2. Why do you say they wont be able to handle exhaust heat?

3. For now, it is a single turbo setup

and here I was thinking I was going to do the first turbo R50...Cheers mate, glad to see someone got around to doing it. I shouldn't be too far behind ya, I just set up my welder a couple days ago.

I wonder if a R51 transmission might hold up better to the boost? more importantly I wonder if swapping any part of the R51 transmission is even possible without swapping in the entire engine, transmission, ecu, etc, etc...

I was told in NPORA forum, that an RE4 transmission from a supercharged Xterra/Frontier. What do you think?

Btw, here is a video of a closer look, I still owe you guys some acceleration videos, but I would like to fix the transmission slip before shooting those videos

This just plain sweet Alfredo! Keep the pics a vids flowing for sure!

thanks man! I will post acceleration vids as soon as I get footage.

Resident HID Troll here, couldn't help but notice; I hope your headlights are aimed lower to reduce glare!

PS: Fix it already! We wanna know 0-60ssssss!!!

Lol of all the things and you notice headlights. I am trying to fix it but I have to wait until early january when my mechanic gets back from vacation

[bucksluts]

Nice ride, it would be great to see a picture from below showing how the exhaust manifold is routed into the turbo. Also, I noticed your worn steering wheel because mine looked the same for so long. Finally got a leather cover (wheelskins), best $50 I've spent on my truck (and no I don't sell them). I appreciate the improvement every time I drive it.

I will shoot a video below the car so you can see and yeh the steering wheel kinda sucks, could you post pictures of your leather cover?
