I'm not criticizing for you not doing the swap anyway. I'm just saying you'll have a sweet truck with a solid axle under it. FJ40 sounds mighty cold for there, might wanna get the hardtop one :D The early 1990's FJ80's and mid 1990's FJ60's they sold in America under the name "Landcruiser" is another good starting point especially for a terrain like yours. Already solids axle with a good steering box.

I know it will be sweet if I go SAS;) Hope to be able to...

I have liked the 40s since I was a little kid, and hope that I will own one soon. Both the 60s and 80s are great cars, but the 60s in Norway are usually crowded with rust. And the 80s are more expencive than the one I god. That the FJ40 is cold is not and issue, since its not a DD. I sell Suzuki cars for a living and drive a car from work, my wife has another car:)
 
Maybe someone on Iceland has used 5:71, but I dont know. According to gearinstalls.com they are much stronger than you think.

I will go for SA if i get it approved here in Norway, the plan is then to use front axle and fittings from mid 90s lj70/73 with coils. But the main concern is legal problems. I have found myself a 77 40 series wich I am going to buy, and I will then consider selling my runner.

r0nin89, we get it. You hate IFS, but why are u posting 5 posts saying the same??? Most of us have learned to read and understand english quite well... and we still run ifs trucks...

I have run my truck with 35/37/38s and soon 36s 15000miles with nothing else than normal service... And wheeled it on snow, mud and rocks... :flipoff2:

Most of the 38" runners and hilux here in Iceland are using 5.71 ;)

Greetings from Iceland
 
Dont go 5.71's! Horrible ring with how thing it is. Personally I wouldnt go lower than 4.88's. A friend runs 40's hawgs and 5.29's with a 22re and he knows its way undergeared. I think the best thing to do to keep your strength in your ring is to get a turbo tranny with the low first gear. That can make up for being under geared just as well as the proper gears.

I'll be running 4.88's with 36's and think that will be perfect.
 
I think 5:71 gears are underestimated... Concidered it for my car, but got hold of 5:29 from a friend who had sold his car! And got them the day I needed them.... ;p
 
If you have the 5.71 gears cryo'ed, you will considerably increase their strength.
 
I've had both IFS and solid axle trucks (many of them lol). Toyota has a good IFS system. I've also had two Tacos. I must say that when 180k miles comes on the clicker, my tacos needed a lot more front end work than my regular IFS pickups and 4runners did. The coils sagged, steeering rack ($$$$$$$$$$$$$$$) needed to be replaced, wheel bearings (dont try this at home!), and control arm bushings all needed to be replaced. The taco front wheel bearing is not something you do at home with a brass drift, a hammer, and a few sockets where the older torsion bar ifs was. And I don't think I ever needed to replace a torsion bar, they could hold the world up. That said in stock form I think an sa truck and ifs truck are equal. Where you may not break a cv on a stock sa truck you will break a j-arm if you are wheeling it hard enough to break a cv, and on an sa truck. Its all a tossup. I think as long as you don't throw a big gaudy bracket lift on an IFS truck it will do fine.

You mean this tranny :D ;


You keep buying it & they'll keep making it, junk that is
85 4R ReT AT
86 4x *ReT 5ps*
88 4x V6 Ex Cab
91 4x 4cyl. wrecked, wont take $100k4 it
92 Fj80 "Superleggera"
94 4R 4x "Baby Cruz"
93 T100 4x 4:87
various Ferrari's & Porsche's
1 MegaCruiser :rolleyes: & a 500D "Magnum PI Helicopter"



This truck was purchased with a 4" "TrailBlocker" already installed. I think I can take it back down, still blueprinting it hopeing the overall weight will keep breaking to a minimum.

You got a CAR you want to put 5:71's in ;p thats EXTREM!!

Thanks for this info, HOW do I find someone that will dip'em?

I have parted two out very NOT impressed, I 2nd that.


BTW, the 86-95 is not good, it's the best!


1: Equal lenght control arms (well almost) very hard to knock out of allignment (CHEVY!!!)


2: Torsion bar on TOP of frame, extremly hard to KO when it's lifted. (NISSAN!!!)
Is there even another manufacture with TB on top?


3: Ajustable suspension, if done right.


4: Torsions can only be installed (2mk) ONE WAY, cant be F'd up. (NISSAN!!)


5: Lots of aftermarket support, as is most often NOT the case w/ many other IFS's.



I can probably continue but I'll stop here :cheers:

OK Knixen, how are the DOT regs in youre country, do you have enforcement officers that patrol the steets looking for "Law breakers"?

Or are you obigated to once a year inspections that you have to take the vehical to?



Is it modifications in general or is it more bumper hight?



My ratonal is (not recomending) IF I wanted to run a 500h.p 22RE, nitrus injected, super motor, bad euough, I would once a year (as per emissions laws in NA) swap my motor have it tested, then switch back, as most enfocement officers here would not know in the event I was pulled or they would not ENFORCE it altogether, (I would cut it off before he could hear it :D)




If it's bumber height I would make a flip down pin in place type bumper, OFF-Road flip up, pin in place, ON-Road, flip down, pin in place.





Depends on laws, just trying to help (cuz I dont know to the extent of youre laws)




If youre lift is alowed??????????


But youre BodyLift isent?????????


:confused: you must have high restrictions

If you use the lift and wheel track formula thingie that I've seen then just ad wheel spacers

The norwegian department of vehicles has controll unanounced along the highways often. But they usually are looking for other things, but If you are pulled over and they see whats installed and not approved on your car you will have a problem. You might have to build your car back to stock.

Or are you obigated to once a year inspections that you have to take the vehical to?

Once every two years you have to get it inspected according to EU regulations.


Is it modifications in general or is it more bumper hight?

It is specific regulations like suspension lift, Body lift, bigger tires and trail armor.

It is easy here to get larger engines approved, because the law doesnt say anything specific about that. But lifting the car....


If it's bumber height I would make a flip down pin in place type bumper, OFF-Road flip up, pin in place, ON-Road, flip down, pin in place.

I am concidering it, but the only thing that REALLY helps is a TUV certificate, which means the products have been tested for your car and is concidered street safe.

If youre lift is alowed??????????

My lift is TUV-approved, and I have gotten a pre-approval to get it into my "pink-slip".

But youre BodyLift isent?????????

Thats right, I could have gotten eather one, bot not both.

:confused: you must have high restrictions

Thats right! :frown:

I aggree, but then theres a problem with getting the increased with of the car. And that will be a bigger problem again...

I have gotten a pre approval on the 4" trailmaster kit with 15x10 -44 rims. And only 31s, I am trying to get it approved with 35s. The bodylift comes off in a week or two...

Yesterday my snorkel was installed, quite easily too.

Some pics...

Suspension lift with BJ spacers (Dont tell anyone about the spacers, just lell'em it sat that hight when you got finished instaling it :D )




or look into a 6" susp lift. (I swear I think someone makes it)

or 4" w/ custom arms (I think once every 2 years you can roll the susp down for the EU thingie)


B.S'em.......................I mean try to explain it's safer (6" kit) than 4" plus BL.




If its bumber hight leave the bumper brakets off (stock location + the approved 4" lift) with BL instaled




I'd call Artic Trucks also, they might have some pull or privy to info you dont know.

I`d rather go SAS... ;)

or look into a 6" susp lift. (I swear I think someone makes it)

or 4" w/ custom arms (I think once every 2 years you can roll the susp down for the EU thingie)

I`m quite happy with my current kit, with just a few modifications it will be great.

B.S'em.......................I mean try to explain it's safer (6" kit) than 4" plus BL.

But the BL is about to come off...


If its bumber hight leave the bumper brakets off (stock location + the approved 4" lift) with BL instaled

Bumper hight isnt really a problem, but I am thinking of making some kind of lover detachable bumper... Just to please them... :)



I'd call Artic Trucks also, they might have some pull or privy to info you dont know.

I have talked to them lotsa times, and they really cant/wont help. A friend of mine works at the norwegian dmv og he says even their approval is a bit shaky. And its part of the problem with getting highted wehicles approved.

But I really apreciate the advice! :cheers:

The thing I have to argue with is that other cars in norway is approved with the same lift and larger tires. So mine should too!!!
 







DANG IT!!!!!






And to think I was cosidering 5:71's


It didnt hit me till this mourning that that link says NOTHING about what diff its for 7.5", 8", V6, DARN...................


and judging by that pinion I'd say it aint IFS front.





I still might just for the heak of it, but this takes a lot of fun out of it.

Thats right! :D

Posting some more pix from the same trip. The last one is when we had to be two pu`s to keep the to cars with winches from not moving and each winch had a snatch block. Then we managed to get the 82-pu out of the mud! It was STUCK!! (It runs on 35x16/15 boggers with locker rear and arb front!) Heavy mud... :flipoff2:
