Haltech Turbo Pathfinder DYNO SHEET

[Towncivilian]

I think he means to use the O/D off button and 2/1 settings on the gear selector. I select "2" when driving through a neighborhood to minimize wasted shifts to D3 and to lessen hunting of gears at low speeds and with variable throttle when cruising at slow speeds. It also keeps RPMs around 2000 at 25-30mph which helps during warm-up, but I digress.

How do you use this "semi-automatic mode"?

put on 1, then at around 6500 shift to 2 before it redlines and repeat from 2 to D

as town civilian stated, except I leave the O/D on

Close ups of the turbo and other piping up top.

What else?

[CanuckQx4]

Could you tell me where the oil feed line is coming from?? If you wouldnt mind following this braided stainless line to where it attaches to the engine. Im curious where our engines have an oil feed.



The manifold your mechanic made up is clever, it appears to be the stock exhaust manifolds, which he simply looped underneath the engine to connect them, and them cut a hole on the drivers side of the manifold and welded on that small piece of pipe to hold the turbo. Kinda clever, I figured making a tubular manifold would be hard as heck

I will found out for you, but unfortunately it will hace to wait until next saturday since this week I left my path for the mechanic to measure the brake space that my path has for him to later install bigger brakes, plus rear disk conversion

What is the 2nd whip you drive? Let me know on the BBK if you get one that works and keeps abs im doing it.

[Pathfinder3.5]

My sweet baby jesus. DO WANT. Thank you for actually taking time to post videos/pictures and keeping us updated through this whole process. You have possibly the one and only turbo R50 in the world.

If by 2nd whip you mean my 2nd car then none. And I will let you know about the BBK and rear disk conversion.

Thank you. It is the least I can do after failing to contribute in any other way in this forum since I suck at mechanical stuff :P

I will post a better video with better shifts next time.

[CanuckQx4]

and the location you tapped into the engine for that line!!!

[Alfredo24.pr]

Will do. Have not forgotten lol

[Alfredo24.pr]

and the location you tapped into the engine for that line!!!

Its really hard to see from above. I will ask my mechanic next time. Sorry :|

Why do you call is Nismo in person? And the nismo badges.. that aint nismo

Why not say "custom"

Thats not me talking and nismo is just kidding. And the badge looks good IMO. Dont you like it?

[SBK03SE]

Sounds good!

[Alfredo24.pr]

Sounds good!

Thanks

[Pathfinder3.5]

I keep showing your videos to my friends and family and all they say is "holy s***". I just keep saying one day...

[Alfredo24.pr]

haha cool

By the way, today I finished installing lower springs from 4x4 but my path looks like it doing a wheelie :/ It looks good on the back but looks even higher on the front..and also installed the rear sway bar from Addco

[Alfredo24.pr]

Canuck: here is the location for the oil feed

[Alfredo24.pr]

Haltech installed. Made excellent gains. Only problem is that my country is only providing 91 octane besides only one gas station that provides 100 octane at 2.69 per litter, and the boost had to be reduced to avoid the engine knocking (i think that it what it is called when there is a weird engine noise due to the pistons or idk). Will upload a dyno sheet in a couple of hours.

A methanol injection kit will be added very soon in order to make the desired tuning and horsepower that I want.

[Alfredo24.pr]

As you see, the max hp was 423.94 at a max boost of 14.93
However, due to troubleshoot of engine knock due to low octane (91 octane gas), it was, for safety, reduced to 12-13lbs for 345.75 horsepower. No engine knock problem but a water/methanol kit will be installed in a couple of weeks along with a bigger turbo for results than can easily allow 425hp. It would easily achieve more but due to stock engine limitations, for safety it will not go not too much over 400 horsepower.

On a side note, the Haltech Platinum Sport 2000, allowed easy tuning and even has a nice launch control that I tested and it felt AMAZING. Boost cut is set at 15 or 16 I think to avoid disaster.

WHATTTT. Dude, AWESOME work!! That is unreal! Makes me want to slap a Turbo on mine. Easy Horsepower for not too much money. The VQ35DE is a tough motor too. Definitely a Turbo candidate without too much work to keep it in once piece.

[Alfredo24.pr]

It is surprising how easily the vq35de gets horsepower...if you can do most of the labor yourself, it would not be that expensive. I cannot wait to get that methane kit so I can run with 420+ RWHP!

the only problem with the haltech was controlling something that I do not know the name, but this custom piece needed to be installed for it too work. I will take a picture of it installed so maybe you will know what it is. I think it is crank something..

[miamiheat3332]

Damn. I have to say in terms of engine work you took your path to where i was planning on taking mine. Awesome work , meth should give you even better numbers.

The vq35 is a well built motor, it cant take TOO much boost though so its not the best either without spending money on internals. For example the 1.8T in my a4, stock is 170hp at the crank, and it can take up to 400 at the crank before you need to worry about changing things.

In terms of original power to aftermarket possible power without rebuilding, the 1.8 wins cause it has the most hp/tq gain without rebuild.

Your vq is making 425 chp, so overall more, but less of a hp/tq gain then the 1.8t, and your starting out with 2 extra cylinders1. and 1.7 extra liters.

425hp is impressive, how is the rebuilt trans holding up? No slippage or anything?

Here are the things id really want to see ( would make me dump the money on collecting parts for this quicker too probably LOL )

- Someone standing outside of the car and launch it

- Couple pull vids, 20-60 , 40-80 etc, i really want to see the midrange and top end improvement, also is your governor removed? Im interested in a 70-100mph pull too.

- 0-60mph time or video

You really have to take alot of pics, and all the info you can from your mechanic so that way for any followers (AKA me) knows what worked for you, and takes out the time of figuring out where to tap oil, etc etc and stuff like that.

[Alfredo24.pr]

The trans is holding up fine, but it just does not allow me to feel that power like I want too, but its still good.
Governor is removed, I made a speed test at a half mile bridge and reached about 130 mph at no problem and still had time to brake.
I will do my best to get all that. I have just a couple more weeks for the semester to end.

[miamiheat3332]

Ours tops out around 130 id assume. ( Limited by 4spd trans and gearing )

Still 130 is enough of a barrier for the streets, with gov mine tops out around 107. On a turnpike going 80, 107 doesnt leave much play room while 130 does.

Also how is your gas mileage under normal driving? Same as before? worse? Im under the assumption it could also possibly be better under normal conditions cause you might not have to rev as much.

I drive mine hard from time to time and its not great, now if i had that turbo setup i can only guess . Would cost me $40 in gas for a days driving hahaha.

By the way did you solve your rear suspension issue on how it was sitting weird?

[Alfredo24.pr]

gas mileage seems around the same. I think its because of the transmission that does not allow that much better gas mileage. suspension is still sitting weird..must be the front struts :/

by the way, do you know if gear ratios can be changed? or final drive?

[miamiheat3332]

I think the differential from a manual version of the pathfinder (only came in 01 i think) had a different rear axle ratio because the trans is a 5 speed. But i dont remember if that ratio would help or make it worse. towncivilian could provide insight here cause i know he knows the numbers.

[Alfredo24.pr]

that would be great.

Also, great news!
This tuesday/wednesday the methane kit will be installed along with a larger turbo. So if everything goes right on thursday/friday I will be at 425hp!
