auto for comp car..whats strong

[evanstaniland]

after running into some auto troubles a TTC i am starting to do some research while im getting the old ones problem diagnised!!

i might need to replace the auto in my bundera to something else than the standard auto from behind the 1UZ-fe.
i am after something that is going to be strong and isnt going to cause me grief when the vehicle is put in steep angles, and most of all will be reliable.

i have herd from a few people that maybe a C4 is the way to go??

a mate a work recommended to use a powerglide.

the car is going to be used on road now and then which also might be a contributing factor to which box!
im not sure what others are using in their rigs and buggies but ill need to mate it up to a LT230 transfer.

any info and help would be greatly appreciated!!

Can't help on the other issues, but C4-LT230 adaptor isn't available anywhere AFAIK - so you would have to make it yourself.

[RUFF]

With running the LT230 the easiest way would be to run the Disco ZF auto in front of it. This is the Auto that has now been in my old buggy for 4 years without a single issue and has been abused at every chance. Although i dont know of an addapter to bolt it to the lexus V8.

There really is no adapter commercially made to adapt anything to the LT230. Haultech could make one to mate a T700 to it but you need to sort out your own shifter for the LT230. And then your going to need a V8 T700 and an adapter to your Lexus V8.

You dont want a glide in a street driven 4WD. They need a heap of gearing to get them to work.

what about strengthining the toyota auto?? they can be built to handle big horsepower.

at the moment i have a high low shifter for the transfer and thats it.

i know that Dellow adapters do a bell housing for a C4 to a 1UZ-fe then i guess it would be working out how to adapt the transfer.

what can i do to strengthen the auto box?? is it going to cost me an arm and a leg??


also what would be the best way to keep oil flow when on steep angles?? would i need a deep pan or what??

[RUFF]

Is there any great reson you need to stay with the LT230?

You could adapt the C4 to a Cruiser case. Or again use the T700 which has a lower first gear than the C4 but is more expensive to buy and re-build and adapt it to a cruiser case.

i already have it, have put reduction gears in it and rear disco is going on in the next week or 2...thats my main reasons why i want to keep it

That makes sence now.

[nottie]

Evan doesnt Kneck make an adapter for a C4 to an Lt?
Also i gather the centre diff is welded up as you said you only have H/L
So you dont havea centre diff lock lever?
To adapt levers to the case you could just use air rams

Hey, they can replace clutch packs and bands with higher quality items, different valve body for higher line pressure's. i beleive the larger surf oil pan is the go, and over fill by about a litre.
i have heard around $2500.

no i dont think the center diff is welded, just no leaver!!

thats a little pricey to just throw at something that still might give way!!

will have to wait and see what other options i could take!

still would like to know what some of the others run especially in their buggies

Evan

[nottie]

v6 t700 lt

New one will be a 4 cylinder like a ca18 or somethn with a c4 and a 60 series box.
Mate i would suggest at least hooking somthn up 4 the centre diff lock.

[bad_religion_au]

C4 would be my choice.

are you sure no one makes an adapter to rangie case? i've seen a few C4's with rangy cases on ebay (unless the LT230 is different kettle of fish, then disregard my advice). was thinking about them for the 40 running a ford motor.

what toyota auto you running?

[andrew e]

Get Rid of that Lexus motor and go for a rover v8 and zf, it will bolt straight up to your LT230....

I hope its just somthing simple wrong with yours, have you found out any common failures?

If you decide to go for a zf give me a ring, i only have 4 laying around.......

rover boxes and transfers might be decent, but the rover V8's are no where near comparable to the UZ's

At least the Rover 8s will still run on severe side angles and as RUFF has pointed out about the ZF-LT230 combo - and we ran the same drive train in our moon buggy with GRA gas - they can be punished over and over.

Plus with reduction gears the LT will be at around 5:1.

[bad_religion_au]

At least the Rover 8s

they will? i remember a huge recovery operation one round of OZROCK trying to get Mal's bushranger recovered because it wouldn't run on the angle it was on (bad, but not undriveable by some motors). one bank was full of oil

Marks make TH400 and 4l80-e to LT230 adaptors.

Mals bushy is the first i have ever heard of a rover 8 ever having trouble like that
The old homeless has spent more time on its roof then on its wheels and the thing just keeps on going. The old moon buggies allways kept going (untill they were fitted with coomo engines ) And Tonys old buggy is still going stong
Evan keep ya lexus just get the adapter to a C4 then get Kneck to make you an adapter to the LT230. Bloody good drivetrain then. And as i said earlier hook up ya H/L and centre diff lock to air rams. The same can be done to your disconnect. Dont forget levers were like so last year. Its buttons now

thats what i was looking at doing if a g/box change is needed. i think i can get a C4 with manual body for $1400.
i must be in the old with the leavers!! also would i need an airtank for all those rams?? and lockers?? i only have the locker compressor (little one)

Evan

[nottie]

Easy to make a small say 2 lt tank and run another compresser as i am unsure if the little compreser will be up to it as i think they are for lockers only.
Again i know i am mentioning Kneck but he should be able to hook ya up with a built C4 cheaper then the $1400 you have mentioned. Shop around as youll find thats a little steep. When looking for a C4 try find one with a 9 bolt Valve body as i have been led to beleive off a few auto blocks that they are the better ones to get.
Once all done mate you will have an awsome bloody truck in my opinion as the finished result now looks awsome and kneck did do a good job on it from the pics so was worth the wait.

i havent had a good look around for C4's...but i did find this on ebay

http://cgi.ebay.com.au/ws/eBayISAPI.dll ... :IT&ih=007

i am now looking at the logistics if its going to be possible to run the engine and g/box as a dry sump setup so angles will never be an issue!! just toying with ideas untill i find out exactly what happened to this auto...

Evan

[zuk33]

mate was good 2 c you have a drive at tt..

i have t700 after first drive if was stuffed
got it re built and it is great no probs on angles at all

[nottie]

Evan if room permitts it wouldnt be hard to take an old oil pan off a C4 and extend the depth to make it deeper so oil capacity is increased.
Look for an oil pick up off say a 727 torquflight and extend the tube and mount it in the C4. You could just buy an extended pan and pick up though off the shelf. If closely monitered though i doubt youll have issues as the few at the moment who run C4s havent seemed to have issues yet and i think they are all standed pans.

I like the idea of running dry sumps and it surprises me that alot of guys dont run it on comp rigs, we used to run them in speedcars years back when the engines where layed over on big angles or completely on there side to make sure they wernt sitting down low.

[nottie]

Dry Sumps come at a decent cost.
Unless you know somethn that we dont

have a look at ebay us.

you can set one up for under 1k with the amount of ex stockcar/ nascar etc stuff going around.

[evanstaniland]

i found out today that the g/box is rooted so am needing a replacement...am leaning towards a C4 due to their strength ...

any ideas...

Or you could try Rocket Ind., VPW (if your that desperate) or Summit or Jegs in the U.S.

Whichever way you go a good place to start would be to get kevlar bands, stronger case? (Ultra Case), deeper pan (or the dry sump idea), good set of planetary gears never hurts either (not very nice when they go crunchy crunchy)

Quiet possible to build one bulletproof, it just depends on what your willing to spend...
