TheRecklessEngineer Posted May 6, 2006 Share Posted May 6, 2006 Not sure how this topic came up last night, but it got me pondering..... Now...the series gearbox isnt going to last long on the end of a V12, and assuming you can get hold of whatever adapter plate you need, what would you do? - Use a permenant 4x4 gearbox....then what about the UJ problem in the front axle? Freewheeling hubs? - Replace axles with defender axles? - Use the jag autobox, and add a seperate transfer box? Any ideas? Quote Link to comment Share on other sites More sharing options...
Steve Hiatt Posted May 6, 2006 Share Posted May 6, 2006 Any ideas? Yes, drink less beer on a Friday night. Have you seen the size of these engines? They don't have that much grunt either. Quote Link to comment Share on other sites More sharing options...
Guest diesel_jim Posted May 6, 2006 Share Posted May 6, 2006 I agree with the above, my dad used to have one of the V12 XJS's, and it wasn't that quick really. his next car was the 3.6 XJS, and it virtually matched it for speed. Now, if you could get a RR sport supercharged V8 (or jag XJR supercharged... that's what the old mans' got now!) that is a blisteringly quick powerful car!

will_warne Posted May 6, 2006 Share Posted May 6, 2006 James, the V12 is pretty gutless in standard tune BUT it has a very flat torque curve so would be suited to LR applications. There are also plenty of tuning bits and peices out there which can get you 500 odd bhp out of one of them. Size and weight will be againt you, though; these are BIG engines. In terms of gearboxes, they use either a TH350 or TH400 (can't remember which although I think its the latter). Both of these are regarded as being amoung the best/toughest autoboxes out there and they can be made to take an LT230 off the back of them. FYI the Jag 3.6 and 4.0 form the late 80's / 90s used a ZF4 HP22/24 which makes them relitivly easy to install into a Land Rover. Quote Link to comment Share on other sites More sharing options...
freeagent Posted May 6, 2006 Share Posted May 6, 2006 i'm sure i saw a series truck in one of the landy mags a few years ago with a Jag V12. i'm sure it had the front wings extended to fit it in. as the others have said, its a bit gutless for such a huge lump of metal.... look awesome when all polished up though... i'd go for a small block Chevy, Overfinch have been puting them in defenders for years so it must be do-able in a series truck, and you can get about 1000bhp out of them if you supercharge them.... otherwise there are loads of BMW, Mercedes or Toyota engines out there (straight 6 or V8) if you want something different. I know of a guy who put a toyota 4.2TD in 109 safari... tuned to about 300bhp (put out over 200bhp as standard) it had huge sidepipes on it, and sounded like one of those racing trucks (supertrux?) that race at Brands... m@tt.

will_warne Posted May 6, 2006 Share Posted May 6, 2006 I think the biggest problem with big power conversions is finding transmission parts that are up to the job. If you go for a Toyota engine you could pull the gearbox and transfer box too which would be a bonus. If you were really feeling adventurous you could take the axles aswell.....

Tom P Posted May 6, 2006 Share Posted May 6, 2006 You don’t want a v12 what you want is a, Touareg V10 TDI 313 bhp Twin turbo 5.0-litre 553 Ft/lb *drools* Tom (wishing the impossible lol) Quote Link to comment Share on other sites More sharing options...
freeagent Posted May 6, 2006 Share Posted May 6, 2006 yep, i realy like those cars... and what an engine. had one pull onto the motorway next to me last week, it accelerated away from me, from about 50mph to ???? at an unbelievable rate.... have you seen the power and torque figures available from some of the current range of American V8 diesels.... with a little tuning, the cummins one can put out 1000lb of torque....!!!!!

TheRecklessEngineer Posted May 6, 2006 Author Share Posted May 6, 2006 Hmmm...yes...ive been pondering a diesel v8 for my disco. One day...when ive finished all my other projects (my rr/109 hybrid actually drove today....most exciting!) Anyhoo...it was a passing thought after too much to drink last night. There are far better engines out there Quote Link to comment Share on other sites More sharing options...

istruggle2gate11 Posted May 6, 2006 Share Posted May 6, 2006 i'm sure i saw a series truck in one of the landy mags a few years ago with a Jag V12. m@tt. Yes, he used to post regularly on the LROi forum, not seen him post for a while though (18 months or so), and Im buggered if I can remember is "handle"? Another who has done it used to post on a newsgroup - alt.fan.landrover, which I know was still going a few months back. Quote Link to comment Share on other sites More sharing options...

TheRecklessEngineer Posted May 6, 2006 Author Share Posted May 6, 2006 ....and cleaning stains out of your underwear Easy solution....don't wear any Quote Link to comment Share on other sites More sharing options...
will_warne Posted May 6, 2006 Share Posted May 6, 2006 Easy solution....don't wear any No, I don't think that's a good idea even with vinyl seats... I think the Touareg engine is beautiful. I'd certainly think long and hard about fitting one into a Land Rover to use as a tow barge. The Cummins V8s are also very, very nice. Some are ally blocked too. Mmmmmm...... I know of someone who's thinking about using one in a new project but I won't let the cat out of the bag. Quote Link to comment Share on other sites More sharing options...

Steve Hiatt Posted May 7, 2006 Share Posted May 7, 2006 A while ago I picked up an interesting Series conversion. It has a widened Series 3 body mounted on a Chevy Blazer chassis. It retains the Chevy 350, manual box, axles and bulkhead. The Series body is then grafted around this, using a widened split screen and profiled roof. A huge amount of work and who ever did it did a good job. You can sit four in the front and still have room for a dog! It's in the back of the barn at the moment and I can't find any pics.
