I turbo'd my Nissan Pathfinder y0
 

Yup. Remote style. Quite pleased with how it turned out. See for yourself :)

this is the lineup:



.48/.60 stock SVO/tbird/XR4Ti automatic turbo



rubber oil return... air compressor hose. harbor freight y0!



shurflo santoprene diaphragm oil pump



-4an stainless braided oil feed



cheap ass ebay MAF intake adaptor that DIDNT EVEN BOLT UP. clowns. that's going to have to be redone but it jimmied on there for now



custom maf relocation harness



1g DSM bypass



1g probe intercooler pipes and rubber, truck radiator hose



22" cherry bomb pre turbo, no cat



$5 wal mart chrome exhaust tip with a picture of a supra on the label (SWEET!)





The pathfinder sports a 160 hp/180 ft lb tq 3.0L SOHC V6 (VG30E). The curb weight of it is 4500 lbs. This adds up to one SLOW ride that still sucks gas like mad. Well driving a 400 hp mx3 daily, and I cant have this as a back up. Need... more... power. The VG30E is a pretty beefy motor stock (mine is original and has 235k miles on it) and has been taken to 400 hp on stock internals from time to time. So I had no choice.



Enjoy...



HAVE to start with one of these

And some short clips (sorry, my cybershot doesn't do justice). It actually sounds like I'm driving a turbine engine down the road.

------- sweet ;D INSTA FRONT PAGE

WHY pre turbo glasspack and do you have a pump on the oil return?

Re: I turbo'd my Nissan Pathfinder y0
 

thanks ;D I did it in like 16 hrs.

I posted up my MX3 project with the cummins turbo too... but I guess no one was diggin on it? lol

Re: I turbo'd my Nissan Pathfinder y0
 

Because this is the daily to tow my car to the strip since I just bought stickey Mickey's for it. I don't like noise and really wanted to quiet it down as much as possible. Plus I use it to tow a dirtbike trailor, I got an 01 Yamaha YZ 250 that i ride as much as possible during the summer :) Also with gas prices these days. Stay out of boost, and turbo'd vehicles get better mileage. I confirmed this with my car, 2-3 mpg more than n/a.

I do have a pump. I bought it a long time ago. Its a shurflo 8000 series with an oil safe diaphragm. I had almost all the stuff to do this project except time. the mx3 has been keeping me real busy. Plus school and work... :3

Re: I turbo'd my Nissan Pathfinder y0
 

That tbird pump on that motor has insta spool. lol i would deff drive it.

Re: I turbo'd my Nissan Pathfinder y0
 

sweet but fix the pics

Re: I turbo'd my Nissan Pathfinder y0
 

thanks. I double checked and I had them linked right? They show up for me. Are they not loading for you?

Re: I turbo'd my Nissan Pathfinder y0
 

super titS! :6

Re: I turbo'd my Nissan Pathfinder y0
 

Thats ridiculous man. I love it. ---- gas prices i would drive it like its stolen.

Re: I turbo'd my Nissan Pathfinder y0
 

So what did you have to do for fuel manegment?

Re: I turbo'd my Nissan Pathfinder y0
 

I have a vortech 12:1 fmu, and one extra injector turned on at 3 psi.

I put a wideband on it last week. It still is like 14:1 at the onset of boost, and between 12-13:1 toward redline. It is detonating so Im trying to stay out of the throttle right now. Im going to add another injector turned on at 1 psi which should help out quite a bit. I also need to bypass instead of venting to the atmosphere, thats killing fuel economy because it runs like 10:1 on the interstate.

Re: I turbo'd my Nissan Pathfinder y0
 

---- thats badspec :6
Sounds very nice indeed , solid work man.
Front Page :y

Re: I turbo'd my Nissan Pathfinder y0
 

wacky setup, i love it

Re: I turbo'd my Nissan Pathfinder y0
 

dude thats great. I love my remote mount on my blazer. you need a FMIC that would throw so many people off. Good work man.

Re: I turbo'd my Nissan Pathfinder y0
 

Did you try adjusting the timing at the dizzy any? That might be enough to eliminate detonation.

Re: I turbo'd my Nissan Pathfinder y0
 

Hows the oil return?

Re: I turbo'd my Nissan Pathfinder y0
 

I think hes running an oil pump , looks dodgy as hell tho !! ;D

Re: I turbo'd my Nissan Pathfinder y0
 

yeah its a shurflo oil pump. you can actually see it in one of the pics, it's mounted to the frame behind the turbo. i need to build/buy a timing relay to keep the pump running an extra minute or so to scavage all the oil out after i shut off the engine. right now it's pooling and on start up i get smoke for a minute or so, and its blowing it into the charge pipes too. :3 it's fine when its running though....

as far as retarded the timing at the disty, im just gonna add another extra injector and run premium. that should take care of that :) i should probably put a boost gauge on it as well to see how much boost its actually running!

Re: I turbo'd my Nissan Pathfinder y0
 

Wow solid work dude that is ------- bad ass :y I bet that V6 is pretty torquey now.You are a regular HMT superstar with the Holset powered MX3 and now this :6

Re: I turbo'd my Nissan Pathfinder y0
 

intercooler or alchy/water injection could help with detonation as well.

what kinda boost are you running?


or what about an MSD BTM?

Re: I turbo'd my Nissan Pathfinder y0
 

uh sweet

Re: I turbo'd my Nissan Pathfinder y0
 

You need to retard timing.

Welcome to HMT superstardom. Good job!

Re: I turbo'd my Nissan Pathfinder y0
 

Get a Fuel pressure guage. That Vortech 12-1 should easily make too much fuel for you (you are fuel injected, right?). I had to recalibrate mine down to 3-1 or it would flood the motor.

Re: I turbo'd my Nissan Pathfinder y0
 

12:1 is standard for some cars, it really depends on the engine and injector size

Re: I turbo'd my Nissan Pathfinder y0
 

stickied ??? :l

Re: I turbo'd my Nissan Pathfinder y0
 

^ x2, um who stickied this and why?

Re: I turbo'd my Nissan Pathfinder y0
 

idk
omg i did a remote setup very similar on my ES 300 years back.

Re: I turbo'd my Nissan Pathfinder y0
 

wow this setup is pimp. but, i dont think that resonator is doing anything there but choking the exhaust flow going to the turbo. the turbo itself disrupts the flow therefore reducing noise, and adding the resonator afterwards would increase its noise reducing capabilities. if you want to make it quiet, youll need it after the turbo. but deam that setup is gggg g unit. :8

Re: I turbo'd my Nissan Pathfinder y0
 

i put a gauge on it yesterday. 6 psi. It was enough to ALMOST hang with a local guy's late 90's mustang GT. lol. i think on 10 psi I should be able to take it from a roll. not bad for 4500 lbs with a SOHC 3.0L V6.

I think I may go ahead and kick back the disty timing a few degrees like some other guys suggested. I also need to richen it up as it is anywhere from 12-13.5:1 under boost and that's definitely asking for trouble. The detonation I was having was on some 85 octane I had left over in the tank though, and now that I have premium in there i'm not hearing it anymore. still would like to richen it up though, so im adding an 8th injector.

Most likely because it's something different, made on a budget from junkyard parts. Isnt that what homemade turbo is all about? Plus a few people think it's front page worthy. Im flattered ;D


My goal with the glasspack was to reduce engine noise as much as possible, while keeping the turbo blistering loud like a semi.. lol. i also was trying to knock the kit out in one day. it wound up taking two, which was still quite an accomplishment seeing how many problems i ran in to. if i ran the exhuast to the rear i could add another muffler and scrap the glasspack, but this will just have to do because the mx3 is in need of attention and the track just opened for the season!

Re: I turbo'd my Nissan Pathfinder y0
 

How is that E85 working in your MX-3 setup what do yo do about the different octane ratings?

Re: I turbo'd my Nissan Pathfinder y0
 

Its working great. I have a full standalone, so i made a new timing table for it. With 9.2:1 compression and 15 psi of boost, I need that 105 octane! pump gas is simply not safe even with running 10-12 degrees total timing, and not near as powerful

Re: I turbo'd my Nissan Pathfinder y0
 

Tony Leung's 3.0L v6 turbo camry was running 20-24psi on a GT40R/88 on 10.5:1 CR pistons.
pump gas + water injection.


pump gas ftw :)

Re: I turbo'd my Nissan Pathfinder y0
 

E85 is $2.60/gal, 91 octane is $3.55 right now. Its cheaper to run the E85. not a whole lot, but enough. i had water injection on my last motor and it didnt make this much power. it displaces air/fuel in the combustion chamber. it was also a pain in the ass to keep full..

Re: I turbo'd my Nissan Pathfinder y0
 

Since you need 40-50% more E85 it actually costs a few cents more than premium.


Insignificant.

Re: I turbo'd my Nissan Pathfinder y0
 

I get 28 mpg on gas, 20 mpg on E85. Cost difference isn't that drastic.

I suppose the reason my old setup with h20 injection didnt work out that well is because it was a pieced together kit i used to replace an intercooler all together, and I was running 17 psi of boost. I was spraying windshield washer fluid (700cc nozzle) and my charge temps were still through the roof (270 degrees) and it would detonate. The more I ran, the more power it lost. It would bog out I was spraying so much fluid and it still couldn't combat the charge temps. that being said, my best time with the car was on that setup. 13.0 @ 110. But I havent had it to the track since, and that was on a different turbo too...

I may set up a kit for the pathfinder though

Re: I turbo'd my Nissan Pathfinder y0
 

No, you don't understand what I said. For a given mass of air you have to inject 40-50% more E85 than gasoline in order to acheive stoichiometric. You spend about 30-50 cents more in E85 for the stoichiochemic equivalent of a gallon of gasoline at the prices you stated.


You've been reading net bullshit on water injection. I have a sweet Water Injection Myths writeup in the Engine Management forum that you should read. Here, since the search engine sucks I googled it for you:

https://www.homemadeturbo.com/forum/...?topic=48057.0

Re: I turbo'd my Nissan Pathfinder y0
 

Oh I understand just fine... One gallon of ethanol has 70% of the energy of one gallon of gas. Right now I have a tune for E85 that is 14.7:1 under cruise all the time. I get 20 mpg consistantly with E85 vs. 28 mpg consistantly with gasoline. They are two different tunes I made. The E85 I added ~10 degrees timing across the map. 20/28=71.4% of fuel economy of gasoline. Right now Im paying $2.60/gal for E85 vs. $3.55 for 91 octane. 2.60/3.55=73.23% of cost. In the end, while I burn more, I spend almost the exact same to run 105 octane fuel. So my initial number crunching in my head was wrong and E85 does actually cost more. A few cents more at the current prices, but that's okay with me. It's also much cleaner smelling and since I don't have a cat, stop and go traffic gives me headaches with the exhaust. It works out perfect for me. Ive put 40k miles on this car, and I mainly use it for commuting on the interstate and I keep a close watch on my fuel mileage when Im not boosting. This isn't theory here, but rather my actual recorded mileage
Thanks for the link, but for the record I havent read anything. I had it on my mx3 two years ago and thats my experiences. Under 10 psi it dropped charge temps 70 degrees. Anything over 12 psi I was getting higher and higher until my target boost (17 psi) which pegged out my IAT sensor at 270+ degrees. I had a setup pre turbo and sprayed washer fluid. I had to run 11 degrees total timing or it would detonate. That was on an LM-1 reading 10.5:1 afr's.

With my cheap ass SS auto intercooler setup now it's 120-130 degree charge temps, 28 degrees total timing, 12:1 afr, and 15 psi boost thanks to E85. I scrapped the water injection. Filling the tank was getting to be a pain in the ass, and I burned over 20 gallons of it over the coarse of a year. Since I was running non intercooled, I was having to inject too much to see a temp drop, and the charge temps were too high for my comfort with the boost levels I push. On 5 psi less boost, I'm trapping 4 mph higher now in the 1/4 mile with an intercooler vs. my old setup. I broke 3 pistons when I had the water injection setup, and haven't exactly determined why. I was injecting a SHITLOAD though... 700cc

My setup was never perfected and I never claimed it to be. For my goals, the intercooler setup works just fine, and with the cost of fuel it's no different to me to run E85 vs. 91 octane (7 cents/gallon is nothing to get worked up over when gas is nearing 4/gallon). This car isnt a race car, it's a daily driver..

EDIT: I read through some of that info. Crazy stuff, contrary to popular belief. Im just curious why with my setup, my results were far from great...

Re: I turbo'd my Nissan Pathfinder y0
 

There's a lot that can go wrong, what you stated as your experiences are incorrect.


For example, this never actually happened. :P


Well...


You've not mentioned anything about how you deduced ideal ignition timing, plug readings, etc. There's a lot going on underhood of a car.

Anyway, I really do like your truck, it looks like an awesome project. I didn't mean to derail your thread so much, just wanted you to be safe and not end up with a pile of work at the end of the day.

Re: I turbo'd my Nissan Pathfinder y0
 

E85 burns in such that it can take more timing and leaner mixtures vs straight gaoline, not just based on octane. So you're making power for longer with less gas. You know its not that simple, but it boils down to that. And since cruising uses most of your gas, it becomes a wash. He's also talking a DD car, not a drag car that spends 100% of its gas on the 1320.

btw as for emissions, NOx peaks at 16:1 for gasoline, so don't go all that lean if you get it emission tested.

Re: I turbo'd my Nissan Pathfinder y0
 

The problem with E85 in a DD car is that You pay atleast a 30% penalty in raw energy, the fuel consumption is much higher. The fact that the octane rating is higher is useless in a DD.
Bumping compression up from the now modern 11+:1 to 14:1, and re-profiling cams & head porting /vvt systems to fix the charge helps regain power, but to keep it simple, there's not enough to off-set the fact you're still using alot more gas, and not making the same power.

Now you go huge effective CR's, cam/port's to match it in a race engine. Ya, but E85 in DD cars is a joke.




E85 in the majority of the US is MORE expencive that normal gasoline because of it's very low supply. (I have, in all honesty only seen two E85 pumps in my life in Alabama. You go to any corner gas station near any race track, or any Sunco / Phillips, etc. and you can find 100-115 octane pump gas. Expencive, but you can find it.)

Now, if you go to Europe, or parts of South America. E85 - E100 is SIGNIFIGANTLY cheaper than gasoline. We rescently had a discussion of E85 in Europe VS NA in another forum. For the guy in Europe that asked the original question E85 is an OK alternative
