Outer Limits 4x4 Board

Guys,
Who knows of a place that has done a C4 to LT230 conversion???

I want to put a C4 behind a Rover V8 and still run a LT230.

Anyone ?????

Clarkie

Why not go for the back half of a LT95 with the C4 bolted up to it probably stronger and theres a few different high range ratios available i have one sittin here with a recoed c4 hangin off it

Nobody, ritters did C4 (C9+10) to LT 95

Hi clarkie about 2 years or so ago I found out about an engineering company doing a lot of land rover adapters and stuff in perth WA.
I sent them an email about an adapter for a c4/c9 to lt230 as I was looking at putting a windsor and c9 into a RR .
They were kind enough to give me a phone call over here in vic. I cannot remember the name of the co. They told me they don't make a kit for this but anything is possible.
It would have to be a one off and would probably cost $1200 to $1500 EA. that is per unit not a firm price though and would have to be an order of 2 of them and cheaper if they made several. As I didn't progress with the project I cannot remember who they were but they were very helpful. Maybe someone over in the west knows who they are. Hope this helps.
Cheers

I guess a c4 may be cheaper to rebuild but wouldnt a zf 4speed be a better option. A lot simpler and the price of the adaptor would make up the difference in rebuild costs.

Is the TF727 an option?

Not 100% sure...but I think POS' buggy is running a C4 with an LT230. Maybe try a PM to StrangeRover or POS, or just call Haultech and ask them.

I know that they already made an adaptor for T700 to LT230.

The reason i want to go to a LT230 is i have Maxi Low gears in a LT230...

Why a C4 over a ZF?
C4 Stronger and cheaper to rebuild.
ZF's are about $1k to buy 2nd hand and $3k-$4k to rebuild.

Thats the only reason..

Ohh i have a ZF, just looking at other options when the ZF dies...

What is it, a 22, or 24. 22s here go for 2-300NZ second hand. C4s are cheap to rebuild, and lots of upgrade parts available, but they are only 3 speed so no overdrive will cost a bit in fuel consumption. TF would be a more available option but the same 3 speed. Is it a 4.6 engine?

not a 4.6 yet....
TF are great, but suck HP like its going out of fashion...
Fuel is not an issue, its a County... and a bush toy.. not a daily driver..

M. Clarke,

You are roughly correct with the cost of auto rebuild. I had my new C4 (that turned out to be a C9 which is stronger) rebuillt for the grand sum of $850 by Colin at Tradematics in Geelong. It was more of a bulletproofing exercise and is still fantastic behind a 350 Chev some 50k km later.

I really wouldn't die in a ditch about the LT 230. If you go the (Ritters) LT 95 TC part you don't have to worry about changing TC mounts or driveshafts or gear lever positions. All stock holes/lengths.

You are very welcome to PM me to have a look/ drive of mine.

Yeah, if i use the LT95 then i cant use my Maxi crawler gears.... they are for a LT230

TF's appear to suck so much Horspower in a Rangie because of the high range ratio, not so much the auto despite what every pecker believes

TF 1.003:1
ZF 1.22:1

Bit easier to get of the line with a 22% underdrive

Use a Torqueflite

OK so a TF with Disco ratio's or county ratios in a LT230 would then be ok...

Better, depending on gearing and tyre size

Best way to overcome gearing issues is more Hp

Ironically I bought a TF727 for the 1:1 LT230 bolted to it.
I now have a TF727 with a 1.2:1 LT230 I don't need.

Shame about the freight, my TF727 (without LT230) is free for pickup.

Next question....

is the input shaft in the LT95 from the C4 ritters conversion the same spline as the output on the LT77, R380 and ZF???

if so i'll get an adaptor made..

the input gear I have from a lt230 with a chev 3 speed has 28 splines and just under 30mm diam shaft, I cant remember what the ford 28 spline dia is now, may be of use to you.

i have a schuler with 308, tf and lt230, don't know much about these things. All i know is the 230 is out of a disco, it was fitted when the viscous transfer died.

It's just sitting around, come have a look if you wish, the rangie is in Silvan, just around the corner, keen to get rid of it, have receipts for a very recent rebuild.

pm if you are interested.

Cheers

FYI, the C6 is a COMPLETELY different box, to the c4 c9 10 family.

Overkill Engineering should be able to do the adapter. They have done a few C4s to LT230s now. We have done one but Overkill built the auto for us and modified the output shaft...we (Adrian) just made the adapter plate.

Can they fit a lockup converter to the TF?

Pretty sure they already have a hydraulic lock up

Overkill in Oz or the USA??
