Rosie, a 1995 Landrover Discovery, with a difference...

Very cool op.
Couple of questions and apologies if I missed the answers already.
1. What turbos did you use on the 4.6? And how did it perform? Any idea on power numbers or a comparison to the Ls motor?
2. Are you still running a manual with the LS motor? If so what one? An R380 with a Marks adapters? Just wondering how it’s all holding up.

The turbos were Rotomasters on a T3 flange. I don't have any more information than that. They were a little bit laggy with the low down torque orientated cam I had, but I suspect that was as much to do with them being an old design as the size.
Performance wise I don't have any figures and there's no point in guessing as we all like to guess high!. It was significantly better than an NA 4.6, but not a patch on the LS.
Interestingly a little bit of tuning of the VE and ignition tables has turned the LS from a big, very torquey slightly lazy lump into a complete animal and that's before a cam change or LS3 heads..
I'm running an R380. I guess it will hold up until it doesn't.
In an ideal world I'd like to go for a 6 or 8 speed auto, but I can't afford one and the 4l80e doesn't have enough ratios for my taste.
I never did confirm that a liner had slipped, just that it had overheated. When I get around to it I'll flog the 4.6 setup with the turbos, ecu and pipework as it's just in my way now.

Thanks for the update. Did you use the Marks adapters from Australia? I’ve been looking at doing this but could find almost nobody running the R380 and an LS as the R380 is only rated for circa 260ft lb.
How many miles have you got on this combo?
I think the late Monaro and C6 Vettes use a 6 speed auto (6L80e maybe). Not sure if it’s physically similar to the 4L80e. As you’d need to connect it to the LT230 still.

Yes, it does look awfully similar, doesn't it? Same numberplate and everything! The owner is a little slimmer and has shorter hair now though!
At present I'm getting around 15mpg but hope to improve that to 20+ with tuning and some more road orientated tyres. Would you believe that 33" mud terrain tyres don't actually grip that well on tarmac?
The dog isn't actually mine, he's my Mum's. I just borrow him occasionally. She has an Octavia vRS estate so I think the dog is used to going quickly...

the 4l80e and the lt230 are a good match though- Mez won't mind me posting this here http://mez.co.uk/4l80e-new.html Bottom of the page are my photos of the marks adaptor setup

Ha - small world. I have this thread bookmarked, and I used to work with Mez, and he got some of his Megasquirt kit from another chap who used to be on another forum I frequented (Se7ens.net).the 4l80e and the lt230 are a good match though- Mez won't mind me posting this here http://mez.co.uk/4l80e-new.html Bottom of the page are my photos of the marks adaptor setup
