Outer Limits 4x4 Board

hey guys
ok i bought a bj40 a while bak and i have worked out wat mods im gonna do to it but i just need some advice on wat order i should do them in! here are the list of mods im going to be doing:

1. 60 series diffs
2. SOA
3. 36" tyres
4. 308 conversion
5. roll cage
6. extend wheel base(rear)
7. new drive shafts
8. powersteering

i would just like someones advice as i dont want to do things twice!
thanks mitch

love to do some of these mods myself to my middy

I would think that in this order:

A) points 1 and 2 together because you don't want to have to cut and rotate 2 set of axles, and probably points 6 & 7 at same time. oh and point 8.

B) bigger engine point 6

C) bigger tyres point 3. will have the power to spin them and strength to not bust things (would have thought 40 series stuff pretty strong anyway)

D) roll cage in between times

Bluey

i guess it will come down to what is current spec of the vehicle, where and what type of tracks you want to do, size of your wallet and your own skills/facilities to do some/all of the work

thanks mate! any other suggestions??

id have to agree with wat bluey said. pretty spot on i think.

Do the engine and then start at the bottom and work up, ie the suspension after the engine

i was gonna leave the v8 till last as im on my L's now and i wont be able to drive it if it had a v8 until i get off my P's! would my stock motor be able to handle 35's or 36's?? its a 3.0 B diesel!

36" TYRES, th best ting you could do (IMO) and yes your 3b will do it if you dont want a race car , TYRES!!!

Headlight fluid is a must

well ^^ that just shows your lack of knowledge on this subject! and your avatar explains you perfect coz thats all your doing in this thread!

Hey micho, what condition is truck in? this is important when you start building, you dont want to have domino effect of failing parts once you have finished..

Chances of fitting 35's or 36's with out suspension and cab mods are slim to none. Go with a 4" spring lift and 2" cab lift first so you can get your tyres under.

Why pay for hard new leafs that cost a fortune, and then f*#@ around with a body lift. When you can use the nice soft worn in factory leafs and do a spring over which gives you 6" staight up.....

Spring over = Roll over...

But each to there own.
I agree with the comment that you'll struggle to get 36's on it successfully without lift.

My advice is if your serious about all these mods then do it once and do it well. both diffs out. Extend your wheel base and drive shaft. Do the 60 diffs and SOA. This way you can do all the work to compliment each other. then once your diffs and wheel base are right look at some 36's.
once you get sick of the lack of grunt with 36's then do you 308. After that some lockers and lower diff ratios to keep you low range low. when your done there you'll scare yourself enough to need a roll cage. Then while the cage is going in you may aswell spruce up the interior. once the interiors schmick you'll need some nice paint on the outside to match. that should keep you busy and broke for the fist five years.

This doesn't always work... The V8 in the Middy only fits properly because there is a body lift there.... long story.

The good bit is that you're planning the whole lot from the start. It may turn out best to drive it stock for a while, save up a heap of $$$ then go nuts and do the engine and the susp / power steer all together as one big job. That way, u only need to engineer once too.

Plan
Save
Go nuts!!!

i knew i would never fit 35's or 36's under it stock coz i have got 31's on it now and they rub at full flex! so it sounds like i should do the mods in order:
1. SOA and 60 series diffs
2. extend wheelbase and lengthen tail shaft
3. power steering and tires
4. 308
5. roll cage!

i think thats the order ill do it in!
thanks mitch

Is a SOA legal where abouts you are? Woulda love to SOA my truck but its a no no in qld, and the fact the rear was sagged 2"

I recon u got the order spot on, Good luck with the mods mate!

Troy

im in sydney! im pretty sure its legal but ill check just incase! thanks for all the help everyone has given me! if i have any probs ill let yous know!
thanks again mitch

Hey mitch,
i have similar plasn to you for my fj40. my rego runs out in feb and i am thinking in the 3month period i have before i need a rwc i am going to buy a 60 and put diffs steering and suspension in it all in one go. prob cheaper for you to do SOA with diff swap and powersteer at once if you can find a rusted out 60. sounds like it should be a beast though

ps go with chev! holden V8's suck balls and have no low down. 350 chev is what you want. there is no substitute for cubes

i would have thought a roll cage would be 1st on your list or at least a roll bar if u intend on driving it,
and holden 308's are ok mine goes hard and is cheap to get parts for.

I know it sounds like I'm being a pesimistic pr1ck but really just trying to make sure u only spend your money once...

Keep in the back of your head things like the tailshaft may have to be lengthened or shortened with the engine conv. (Mine did... don't know about the 40ser)

dam mithc they were pretty much the plans for my 40 wen i get it!!
good luck

already got my roll bar in! that was the first thing i put in it! i only bought it coz it was $100 and im just gonna keep that in until my cage goes in!
thanks mitch

if it was me personally, i would look in to the toyota diesel engines for a engine conversion, a 13bt or even a 15bt would be what i would look at.
Imo i couldnt handle having the 308 or something petrol after the reliablitly and the fuel economy of the toyota diesel, And yes i have access to 308's and 253 (theres one in my shed)

i've got a 3b in my middy and it goes alright. has aftermarket turbo too now which helps alot. bloody noisy thing tho, would love to cut the noise down. must be getting old. oh, and the crappy gearbox lost 1st and 2nd synchro, not sure how long it will last

rollcage and recovery points then wheel it as often as you can

you'll soon see where you want the mods... powersteering is probably high on the list, but you can live without it. the rest depends on how you like your rigs set up. i thought i was going to SOA mine when i first bought it, but after lifting it 2 inches, i decided i HATE the fact it loves to go to sleep so often, so it's gone back down to stock height and i'm running q78's with cut guards.

what about a winch??

narr i wont get a winch just yet! i got a hand winch for the time being!
