Ls1 is the way forward.. but what gearbox?

[nat p]

Mornin all,

Ok we have decided to go the Ls1 conversion for my range rover classic AND my brothers,
The question is do we go straight to a patrol box? OR is it possible to use a T56 gearbox (standard Ls1 box and adapt this to rangie transfer box or should I find a patrol transfer box and change everything!

OR

Sell my range rover and buy a patrol!

Cheers NAT

[uninformed]

what about the chev auto? Pirate4x4 may be a good place to search about chev stuff

[Psimpson7]

Rakeway Engineering can supply a kit to fit a Tremec tk0600 between an ls* and an lt230.

it is a seriously nice bit of kit, but seriously expensive.

4L80E to LT230;)

[blitz]

6L80E if money was no object

[tebone]

Go with the 4L60e out of a late commodore, adapt to lt 230 transfer.
Hyline 4wd in Vic have done a few of these conversions.
Look up youtube " Hyline 4wd"

When i was looking everything i read on the 4L60e to LT230 was all bad, go with the 4l80e, If i ever get a chance and come across a very cheap t56 i will look at doing a custom adapter, i actually spoke to Mal Woods who does alot of work on t56 boxes about making an adapter, he quoted me some pretty big dollars to do it but said its definetly possible and the t56 should hold up it it just fine.

I don't agree with you regarding the 4l60e being all bad. I currently have an 4l60 behind a supercharged 383 chev adapted to lt230. Auto has all new insides 650-700hp ( cost 2k) and has never given me trouble. It has a great low first and good overdrive. Keep the tranny cool and you won't have any troubles.

It wasnt the box that was the bad points i heard, it was the adapters kits leaking etc, when i looked around i couldnt even get a straight answer from anyone on if they would do a adapter for me even though they had done others. Who did the one you have?

I made my own for the 4l60, but hyline 4wd has made a few for the 4l60e. I believe he has had no issue with oil leaks. The tailshaft of mine is very close to trans pan flange which i ground back so the uni joint didn't hit it which it doesn't have any oil leaks.

[cal415]

Sounds good, but whats the old saying? it didnt happen without pics :)

Please post up some pics, keen to see how you have done it, would like to use an LS1 and auto in another truck we are going to build and 4L60e's are common and cheap.

[tebone]

give Hiline 4wd a call in vic he could make you one.

[cal415]

Ok, i dont need one any time soon, but will remember that whe i do.

any chance of pics of yours?

[brend0n]

has anyone looked into the tremec TR6060 as a suitable box.
if a TR6060 - LT230 adapter could be found?

or is the nissan 5 speed about the only practical way to go for a manual LSx

[Bigbjorn]

Have an internet search or buy a copy of Hemmings and look for wreckers in the USA. Chev, Cadillac, Buick, GMC make a wide range of 4WD's. You can probably buy the whole engine and trans package for less than the cost of conversions.

I agree I have an LS1 Behind 4160 to lt230 in a classic of coarse and I flog it.. never had a drama ..just tryng to pull it up...YEA..

[rags67]

are you interested in 4hp22 zf with lots done to it with adaptor custom torque converter and transfercase ready to go? :)

[brend0n]

was anyone looked into the toyota boxes W58 (supra? i believe) to go behind an LS to a LT230?

The Tremec 6 speed gearboxes are very long. I don't think you would get one to fit in a Rangie because there isn't much room to move the transfer case rearwards (floor gets in the way). I have a T56 Magnum at work I can measure if wanted.

[Bigbjorn]

Have you thought of finding a wrecker in LA and buying an engine, transmission, wiring, electronics complete from a USA 4WD? All the big 3 make powerful 4WD's by the tens of thousands and there must be thousands of them in wrecker's yards.

[Pickles2]

Lots of good info hear.
I guess you'll do your homework & work out what's right for you.
Only info I could add, is that I've heard that the 4L80 is very strong, used in SUVs in the U.S., so I'd be having a good look at that one, its ratios, hp & torque capacities etc?

That's a good idea just have to find 1 with driver side front out put. Not many with offset rear....
