[The_Magicians_Eye]

First off I want to see some pics of this beast!!!! Not to many WD21 Nissan Pathfinders in off road racing anymore. We need to see lots of pics!!! lol

[Slartibartfast]

Sounds like fun! You can host pics on Photobucket or another hosting service, click the 'insert image' icon (below the smiley icon above the reply box) and then paste a direct link to the pic in there. Can't wait to see what this beast looks like.

[Precise1]

I'm along with the others, lets see what you have and then we'll talk about mods and your wallet...

I havent brought this yet but i pretty sure its going to happen. I will get more photos in the weekend and then sort out the photobucket thing.

[Brent375]

I am prettty new to whole sport only got involved this year workin as pit crew (Crew Chief) for proformance motorsport

https://www.facebook.com/ProformanceMotorsport?fref=ts

http://www.proformance.com.au/

now this is one awsome truck love working on it. its still in testing with a street 350 chev so down on horse power compared to our compedaters and is getting improved all the time we learn. feel free to like our facebook page. we just finished our first race the other weekend first in class and second outright. Big things to come i reckon. I one day hope to have something like this but dont have the skills to build one just yet. But i reckon we will be highly compedative in our our class with the pathfinder.

 

ps it will be getting repainted the pathfinder that is

[ahardb0dy]

Toyota wheels on the pathfinder, can't really see what was done to it suspension wise. Roll cage inside, doesn't look like much from the pics for the price.

[jj big shoe]

This is it, right?

 

Looks to be pretty well prepped already. Maybe just nut and bolt it, make a few test flights and go racing!

Edited June 13, 2013 by jj big shoe

[devonianwalk]

dang.

[Brent375]

yea have already talked him down in price already at 7500 and havent even looked at it yet hope to get it for 6000 to 6500 i priced up building one and it was going to be alot more $ around 8 to 10 and dont forget im in perth western australia the one of the most remote cities in the world so things are always more expensive

[Brent375]

like seats and belts and cage alone came to about 4000. Then suspension mods etc

[Brent375]

is there any common faults/weak pionts that i should look for before buying

[Leo94]

is there any common faults/weak pionts that i should look for before buying

This should help.

[Brent375]

Thanks there is so much information could spend weeks just reading

[andreus009]

1) I would assume the exhaust manifold bolt issue would have been dealt with already when the for sure put in new exhaust to race it. Just double check/ask.

 

2) Looks to me based on the pictures it is still running stock size tires on basically stock sized suspension (i.e. no extra travel)? I could be wrong, but just from the looks of it doesn't seem like much has been changed there.

 

3) My biggest concern, personally, would be the stock steering set-up. I won't say that it is weak per se, but it does develop some slop/looseness in the steering box with age. it's not terrible but something to be aware. Maybe it has already been upgraded.

 

Well, that's my 2cents. Love the roll cage. Wish I had one. Not that i race, but I do sometimes get myself in hairy situations.

[Brent375]

yea i have already been looking it the calmini steering hopefully will be able to make my own setup. yea not sure on the suspension set up yet as its a bit had to tell the key is to get as much travel as possible but without the lift as the higher you go the more likely you will roll when trying to drive fast and being a production class you are limited on what you can change. but i will no more in two days time. plan to give it a overhaul its half way threw a season at the moment and would like to start fresh and ready next year but will have it out doing a fair bit of testing.

[Precise1]

You might want to look into the HooHaa centerlink option available at gressroots4x4,com coupled with the manual D21 steering box replacement for the idler arm. That would make the front end as bullet proof as possible with the tie rods being the weak link (the best as far as I'm concerned). Easily done for under $500 as well. All the info is here...

Calmini is somewhat of a crap shoot for quality and often you can't get replacement parts without buying an entire new set up. Some people have had good luck/like the products while others have really bad stories. Click on the link in my sig for a brief example...

 

is there any common faults/weak pionts that i should look for before buying

I spy a 5 speed tranny! There is a TSB on 'overfilling' for proper lubricatiion in all situations, the gist of it is to put in 5.1liters through the shifter hole, Redline MT-90 is highly recommended if it is available to you.

The auto locking hubs can be problematic, but it looks like there are manual hubs on already?

[Leo94]

Thanks there is so much information could spend weeks just reading

Welcome to npora.

[Brent375]

yea auto hubs are crap on most vehicles 5.1 litres that is alot . good to no about the calmini steering

[Precise1]

Yes, it is, but go to the Garage/Technical Service Bullitin section to read up on it. The 96+ manual trannys had the filler hole relocated up higher to compensate...

 

Sorry, I didn't proofread, pretty sloppy when trying to provide a link!

www.grassroots4x4.com is the site I meant to say...
