SAS on 1990 terrano: updated 28-11-15

[Dirtydog]

does anyone know if the safari trans will accept the terrano bell housing?

I have a safari trans off a td42, and a terrano trans off the v6. A quick measurement, and the bellhousings look to be interchangable. The v6 bellhousing looks different to the td27t thou.

is the td42 gearbox much bigger?

i have a 50mm body lift and i can chage where the mounts sit to suit new gearbox if neccasary

[kbjj]

The td42 and v6 trans's are the same length and very similar in size. The mounts are in a similar position, but are quite different. The d21 has one horizontal mount, and the gq has two angled mounts. If you supply a gq gbox cross member, it might make the conversion quicker (less fabrication work)

[Dirtydog]

sweet as cheers for that info, ill look out for two crossmembers after i get the trans, but ill have him to have a look to c if he can modify the mounts or not.

[Dirtydog]

ok guys so i need to get a safari chassis from christchurch to gore, but hopefully sooner than later.

is anyone travelling to dunedin from christchurch or to southland from christchurch?

otherwise its gunna be a fun drive / freight.

[Dirtydog]

Great news everyone, chassis is down in mataura and ready to be chopped up,

im quite suprised, i also got a safari steering box and pump, so even got a better pump for larger tyres, but more importantly, the drop arm from the box drops towards the front, not the back, and i got all the linkages with it.

all i need is the gearbox and it is all sorted and will be done.

it will be a while till the next update because im on 3 weeks holiday.

[Dirtydog]

well heres the first major update, we have stripped the chassis of mounts etc on both terrano and safari donor chassis, and have measured up where the diff is going to sit.

we have moved the diff 100mm foward for clearance, and so far the only things we have to change is the sump, and the auto crossmember.

heres some pics to keep you all amused:



trailing arm mount cut off



i did have more photo's but left my camera somewhere, will load them up later

[Dirtydog]

Heres the much awaited pictures:

the sump was the main problem, so it had to be trimed up so the diff would clear it

[Dirtydog]

Yay finally its off the hoist and the front diff is in, just have to get the steering rod fabricated up itl be in properly. the steering rod in it now is just a bit of square pipe so we can move it on and off the hoist.

this is what she looks like now with cut safari springs, about 1 inch has been cut off them just so shes level for now.

[kbjj]

Good work, trim them drop boxes so you can slide off banks etc a bit easier. I'm trying to add a cross member or tie rod from panard the mount to other chassis rail, as there is a hugh load on this at times, and its tweaking my chassis. My panhard mount does hang lower thou.
Lots of flex testing for clearances etc before you give it the jandle aye . Give the details on gearbox, bellhousings, clutch components, etc. I'm interested.

[Dirtydog]

we havn't quite gotten that far yet, the axles sitting there with out the drive shaft in it.

its still has terrano gear in it, until we put the rear safari diff in it.

im also tossing up whether or not to put a vh41 with a safari gearbox or trying to adapt the safari transfer case to the back of the terrano auto.

but the driveshaft will clear everything, we just had to trim the sump abit and the cross member for the gearbox will need to be modified, but were leaving that till i decide if im going to put the safari box in just in case, cause we will use the safari crossmember instead then.

and the drop boxes we cant really trim down much otherwise they won't be strong enough for the certifier.

[passengerpete]

have ya got a pic of your truck straight on with the wheels on as im very curious how wide the front track is ? how far do the wheels stick out past the front guards ?
thanks keep up the good work

[Dirtydog]

no actually i forgot to take one, thought i was missing something.

but the tires sit about half out the guard.

im going to be getting positive offset rims so they aren't so bad, unless i can have it legal sticking out this far.

[Dirtydog]

ryto guys have some more pics for ya

the wheels do stick out a bit, i might keep it this way, as it does look cooler, and it would be safer on road to since it will be wider.

[Madaz]

What does it look like side on with that diff pushed forward 100mm?

[Dirtydog]

it doesnt actually look that different to be honest,

you only really notice it when you turn the wheel and there is alot more clearance between the wheel and the guard.

the diff sits right in the top most part of the chassis arch, and the diff can be pushed up quite far in there with plenty of clearance too.

all in all this truck will have a fair bit of articulation by the time we put the rear axle in. it will have more than the safari because of how it is set up and also because the springs are closer together, and the chassis is narrower.

[Madaz]

I was just curious on how much that you can trim out of the front of the front guards to get 35s in?
cheers

[workin on it]

wow great job so far. this has inspired me im saving to do the same to mine!

[Dirtydog]

i can trim a fair bit off, im basiclly going to trim straight from under the parklight back, and as for near the door i dont know if we will have to trim yet as we havn't put 35's under it.

its going to be really easy if i want to lift it aswell, just new shocks and springs.

[Dirtydog]

ok guys so theres a little bit of trouble with certification in relation to hand brakes etc.

apartently if a vehicle comes out with a handbrake that locks up the rear brakes, i.e has a cable that goes to each side, then you are not allowed to put a transmission style parking brake in it.

so this affects me because the safari's came out with a trans brake, so there is no setup for the rear handbrake on the diff. i could use the likes of different calipers that already have the cable built into them but it will be much easier (and cheaper) to swap the safari front ratio to the same as the rear.

it will be easier to fix if the diffs for some reason break etc, because the front and rear will both be 31 spline, so i will in theory be ale to keep a spare for both the front and rear.

now the problem i have come accross, is that both the rear diffs that i have (terrano and safari) are open, so i have no lsd units. im looking at getting 2 mistral diffs for the lower ratio, but might have to go for the 4.6 lsd's from the terrano rear diff.

if anyone have any info on doing these diff swaps please dont hesitate for your input, it would be appreciated

[Madaz]

Seems a bit strange, Ive done rear disc conversions on samurais before , where we have installed the cardin shaft hand brake off a 413 onto them, and heaps of toyota guys have put discbrakes onto the back of the transfercase as a handbrake, and i think most of them got Certs?

[Fakey]

So are you thinking of running terrano gears front an rear?

Also have a re read of the rules ( someone else posted them, think it was in jdubs thread) the Carson shaft can be used as long as the vehicle is fitted with a dual circuit master cylinder, at least that's how I read it

[Dirtydog]

either terrano or mistal gears in front and rear.

depends on what is available.

[Fakey]

Mistral or terrano gears won't work in the patrol diff heads if that's what you're talking about? Only part that will be of any use is the terrano rear LSD which fits in the patrol front diff an works pretty well

[muddyhilux]

check out the link below.look at point 2.3 as fakey said jdub has had it ok'd by certifier and ive heard they're ok and planing on using one on the brother n laws navara

Mistral and terrano gears will work in patrol heads, they bolt straight up - you just need to use the patrol center with the bigger sidegears in the back.

thats what we were looking at doing, but i cant decide if i want 4.8 or 4.6, does anyone know what the mistrals run in them and are most lsd's?

If i was you, I'd definitely run 4.8's, especially if your gonna run 35s.

Mistrals are 4.3, and apparently all are lsd rear.

[Madaz]

The 4.6s in my truck were both out of 2.7 turbo mistrals?

4.8s would have to be aftermarket

[Dirtydog]

im pretty sure i read somewhere some mistrals are 4.8's, but maybe not, im really just after lsd's for it so i can run lsd front and rear, i wouldnt mind 4.6's as thats what it has at the moment, and it doesn't seem to have to much trouble. although i am looking at various diesel v8's that i could fit in there, looks like a 350 chev would be nice but ive only ever heard bad things about them.

does anyone know of any diesel v8s around? i know that fiat brought out a 3 ltr v8 in some of their delivery vans, so maybe this could be an option? just looking for ideas nothing cemented yet.

[u13turbo]

I know for a fact my olds 94 mistral had 4.3s, it sat bout 2200rpm at 100, my terrano sits bout 2500rpm with 4.6's, and you can get standard 4.8's from terranos.
