engine build up is in the works....sent a hefty deposit off to Aus. over a month ago.

What is done so far is...

-injection pump fully rebuilt
-flow/ported exhaust manifold for better performance into turbo
-custom built turbo is done
-cam is being ground right now for performance, soon to be ceramic coated
-radiator has been sent off to have a custom aluminum built to match
-injectors sent off for full performance rebuild
-motor fully torn down and machining in the process
-starter fully rebuilt

Motor may be in the reassembly process within the week! Going to go with a black/silver color scheme on it. Going to have it all dyno'ed once completed, will be cool to see the dyno sheet and what this old diesel is putting out when done!

who's doing the engine work? You or local machine shop?

Sounds like from his post that it's being done in Australia.

Ya in Oz....done up by Yuri 4x4.

Plans are getting finalized for what this truck will be when done and what will be in it. Truck is heading to the fab shop within a week or so....

Going with NV4500 5spd. Have been planning on a STAK behind that but may go Atlas simply because STAK is something like 3-4 months out at the minimum. Will be mounting the NV4500 to the stock SD33T using a Scout adapter kit. Hoping it works out without to much drama.

Body is coming off for full blast then repaint, fix any rust found. Patch up big holes in body too and or cut out more if needed to fit 38"+ tires.

Here is the real expensive part though....I am 90% sure atm I will be using a set of Portal-Tek custom built 9" diffs, http://www.portal-tek.com/index.html. I know I must be crazy considering how much they cost! But imho these are about the best diff you can buy. I could keep the stock diffs but it creates some problems. So I am really leaning torwards the Portal-Teks. We will also go full hydro steering. If I give them 50% down by Friday I get a set of free ARBs in the diffs so that certainly is making me think hard about it. These are 60-70 days out which means if I do it they will be in the truck by the AZ Run!

Other things are in the plans for the truck this winter. Without blah'ing on though I will save these for another day. Basically I am wanting to just finish this truck up and be done with it. Should pretty well get there this winter depending on motor and where I cap this $$$ wise.

As far as what I did with parts already removed, ie C200 rear diff. It is sitting in the shed along with the other stuff!

This Patrol is not going to be all Nissan anymore. To get it how I want there really is not any good way around that. The engine will stay Nissan along with frame and body. That is about it....and I am ok with that. There is always other Patrols! In fact I for sure will use everything off this Patrol in another build up, likely on an old 60 series Patrol.

ill take it youll be on a trailer comeing down

There's some big rocks in Turkey creek you can play on

I have mixed feelings about portals off-road. Yes they are the ultimate off road axle however they are fairly new to the hardcore off-road scene. I think dynatrac has them beat for legendary and reliability. They definitely have been tried, beaten and proven their reliability.

The only thing that would worries me about the portals is what happens when the front is locked, your in the throttle and a tire catches. That would be a crazy expensive repair.

As for your patrol still being a Nissan. When you get into the serious off road stuff there's usually not much original stuff left. Pretty much the only thing left untouched on my truck is the driveway and the body. The tailgate no longer says Nissan.

Atlas or STAK. They are both good choices for aftermarket t-cases. Have you ruled out the possibilities of a doubler? As for me I'm pretty much set on the ATLAS 4spd. Totally customized for what I need it's like $3400. That's a pretty nice chunk of change for transmission related part. After the purchase I never plan to worry about the t-case again.

Ya no matter what happens MQ gets trailered to Arizona, same as last year. The truck became a trailer queen awhile back. Well it has never been good for road trips....top speed of about 65mph. Plan is to always keep it road legal though and should be able to do 200 miles or so on pavement to get to trails no probs.

Hope there is some good stuff on this years AZ Run.

There is a pretty big difference between a Mog or Volvo portal and the Portal-Teks. The Portal Teks are in thier generation 3 and have many if not all probs worked out. I honestly don't think breaking them is much of a concern, especially with a Nissan SD33T powering them. Portal Teks can be had with either a CV set up or a uni set up. Forgive me I am new to the uni set up in a steering axle but....the unis are from a D44. Yes a bit small for a 1.5ton diff. Thing is the drop boxes increase strength by 2-3 times. Also there are some upgrades available for the unis which would be stronger than I will ever need. I also don't see ever going over 40" rubber because this will always be a bodied rig, never going full buggy with it. I think I will destroy the frame before I would destory the diffs.

From what I have read the portal diffs cause a ton of axle wrap. So buffing up the links will be required. My fab guy feels if we don't change wheelbase or anything like that it won't be to hard to fit them. Clearance under the sump is a concern but the new engine is a dry sump so that will solve any worries there.

The main difference I have read between the STAK and Atlas is the size of the box. Atlas is bigger....this may be the deciding factor since we only have so much room between the frame rails. Ya the t-case will be in the $3-3500 range. This is the one item I really need....to get my gearing where it needs to be. Not going to go doubler route....Stak or Atlas is it. Klune would be cool but don't think I will need it and the truck is a SWB even with stretch wheelbase so room will be a problem if the drivetrain gets hella long.

Got an email about the engine today....Most of the outsourced stuff is getting done. All machining is done, top and bottom plus porting and polishing. Custom aluminum raditor just came back and is done. Intercooler, turbo and dry sump are done and at Yuris place. Injection pump is all done and so are injectors. Starter motor is done and fully rebuilt. All rebuild parts are in and at Yuris shop, pistons, seals, gaskets, ect. Cam shaft has been modified and is done. Got a super charger to buy still and few other things. Yuri is planning to start the reassembly and build up right after the 1st of the year. Which means I won't likely see the engine going in the truck until mid-2009.

As far as keeping it all Nissan...you are right. Once you take that step to the real deal not much can stay Nissan. I just simply can not get the tire size I want and gearing plus keep it Nissan. Not without spending a ton of cash on stuff that is not the strongest out there. Result would be high dollar parts that are only middle of the road for strength. If I was to say what I have in the Patrol diffs you might be suprised. The Portal-Teks are about 20-30% at the most over a set of Dynatracs or Currie build diffs. This makes the Portal-Teks look real good to me and I have had my eye on some portal diffs for at least 5yrs. When you add in the cost to ship stuff from Oz it makes Patrol parts real expensive. My plans for awhile has been for this truck to be my serious off-roader. That is it, nothing else. And once I decided to get lower gearing the plans to keep it Nissan just kind of faded away. But like I say there will be other Patrols. I will likely use all the MQ gear in an old 60 series especially since it is all new and ready to go for that kind of thing. Keep in mind the Aussie guys use Nissan stuff because they can't get D60s and the like easy or cheap. This is why there are a lot of products for Patrols in Oz which is great. But when comparing products and cost of stuff using domestic gear starts looking a lot better simply due to strnegth, cheap available parts and cost. Buy a set of GU diffs, H233 front and even H260 rear, rebuild them and buff them up, fit lockers, ship to the USA, ect ect and you can quickly hit the $8-10k mark.

I have plans to buy and import a 1987 GQ Patrol in 2012. Have had this plan for years now! That truck I plan to go with a TD42 diesel and keep it all Nissan. It will be my tourer or expedition type rig. Something I can jump in and drive to South America if I want (and I want to do that some day once I speak fluent spanish) or bring it to an AZ Run or do mild trails in Moab.

So the MQs fate is sealed and I foresee myself owning for at least 10 more years if not 20yrs!

Hi Fudd
I already bought the Super swamper tires 35/10.5/15 so i will go for the mod in the suspension, I'm planning on going with your suggestion, 3 links in front and 4 links rear with 2.0 Fox air shocks 12" or 14".
I have read that there is not an easy way to manage the diferent positions of the shocks, is it true?
I have another questyion, I read about the Klune-V "Extreme Underdrive, did you finally bought it? it was easy to assemble? it sound marvelous, do you think i can link it to my transfer (original)
After some time of doing the job one question to do is if you could go back in time you will do the same won't you?

Hey man....

First off my name is Ian not Fudd. That is just a nickname I used when I signed up here many years ago. So please feel free to call me by my real name which is Ian.

Next do you live in Colombia? I asked it before but don't think you replied. I ask because I have been to Colombia 2x and will be going there again in about a month or so.

Bunch of questions you ask there and not real easy to reply to them. Everything you ask about is all custom and there are not off the shelf stuff to modify your Patrol to the point we are talking about.

If I could do it all over again would I do it the same? No definately not! I would just skip spending money on the Nissan 5spd tranny, transfer case and diffs. And go straight to what I am planning now and going to be doing in the next 3 months. Which I think I described a lot already!

You have go to ask yourself what do I want out of my truck. It seems like you have done that. But you need to know if lockers in the diffs and good stock lifted suspension is enough for you. I am guessing it is not enough for you since you have bought 35" tires and are wanting info from me on modifying your truck beyond that regular old modified truck.

I got to say 35" tires are not going to be real good even if you change gears in diffs to 4.6s which is basically as low as you can go. With the 4.6 gears in the diffs and 35" tires you will be fine for regular off-roading but when you need to go real slow like on rocks or really difficult terrain you need lower gears. You can not do anything to the stock transmission or transfer case to lower gearing. So gearing really needs to be figured out when going to 35" or bigger tires.

Suspension will be fully custom and you either need to know a lot about it to do it yourself or have somebody who knows a lot about it. It is not real complex and you could learn and then do it yourself if you know how to weld good. But it requires a basic knowledge of geomitry/structural engineering and how things work in modern day suspension. You also have to crunch a lot of numbers so good math is also important.

Before I say anymore I think you should tell me what country you live in so that I can make the right suggestions.

Hi Ian, my name is Andres and yes I'm in Colombia, good to know you will come, please kep me posted, it will nice to know you and maybe we can go offroading with the people i used to go, if you know spanish you could visi our web page www.fullsizes4x4.com we discuss a lot of things in the forum.

There's no crawler gears available for an MQ case?

Would have thought for sure something like that would be available in Oz.

nope nothing and you can't even do a one off. Reason being, there is no room in the t-case, to tight for any gears. GQ/GU, yes crawler gears available but they use a different t-case. Even the old 60 series has enough room in the t-case to do gears but it is a one off thing.

Oz is really the only place in the world with lot's of aftermarket stuff though....

Hey Andres...nice to meet you! I speak a bit of spanish and am trying to learn more. Speaking fluent spanish is a goal of mine. I understand more than I speak but read/write hardly any spanish.

I will be in Bogota, Cartagena and San Andres Island. My friend in Bogota is a huge Patrol fan. He has 2 Patrols right now. He is a member of Doble & Bajo, maybe you have heard of them? It would be great to get togther while I am there...I will send you a private message about that soon.

As far as modifying your Patrol. Let me give it a little thought and then I will respond more to that. It certainly is doable I just want you to beaware what is involved.
