    [QUOTE=Hoges;1817084]Some tech issues as requested:

    This is a list of changes from the blokes who successfully did this conversion in the UK but unfortunately they ran out of funds to commercialise it properly. Their strategy was to retain the GEMS system and fit the crank/Cam/MAF etc sensors from the Rover V8 to the LS1 block.This means that essentially only the "iron work" is being replaced. However with a low end cam replacement and conservative mapping they were still getting 350 bhp on the dyno. Also, retaining the GEMS meant that Nanocom/Blackbox diagnostics still work...

    Have a look at "EFLive" which enables the original LS1 system to be remapped to the "nth" degree and offers a lot more opportunity to get various "tunes" for very reasonable price...

    In standard form the Gen 3 LS1 cam reaches max torque around 4000 rpm. A different cam offering good torque lower in the rev range would be a great advantage as mentioned. That's where "EFLive" is most useful because it enables one to reasonably tweak the maps, compare them in a spread sheet and adjust them numerous times to get it "just right"...

    The List:

    * Bellhousing changes and torque converter mountings
    * Design/placement of engine mounts to accept the Gen 3
    * Retain standard RR exhaust with fabricated adaptors or is it " custom "
    * Upgraded fuel delivery system?
    * some ancillaries (Aircon, PAS) prob needed to be relocated
    * Same/different alternator? plus wiring arrangement
    * The wiring loom would have needed to be modded
    * Did they retain the GEMS system and use the RR sensors or use a different EMS altogether?
    * did they retain the airbox or use a different one?
    * did they retain the viscous coupled fan or put in an electric fan with an adjustable controller?

    Excited as I am at a LS1 conversion (having had an LS1 for about 10 yrs) I'm wondering if the UK TDV6 conversion might not be a better option ...[/QUOTE]

    yup, more torque and better fuel economy. As exciting as a SB chevvy sounds at 5000rpm, its not what these vehicles are about. Tdv6 ( chipped) all the way IMO.

    Just my 2c.,

    JC

    It's interesting that the blokes in the UK (I mean "chaps" ) who successfully did the LS1 swap, claimed 16mpg (17.5L/100km). They later converted the rig to sequential LPG.

    Stock standard, the P38 currently revs at about 2300 rpm at 100kmh and approx 2550 @ 110kmh.

    In the LS1 Commodore I had, 100km cruise was around 1800 rpm and a shade over 2000 rpm at 110 kmh. At 100kmh with 2 pax + light luggage it drank between 8.9 and 9.2 L/100km on a BNE-SYD run. The P38 does about 12.2 L/100km for the same run.

    An LS1 in a P38 hooked up to the ZF box, we're looking at an additional 400kg approx of mass, plus with top gear in the P38 equating to 3rd gear in the Commodore, the LS1 would be revving 500 rpm higher at cruising speed...albeit with 1100cc extra displacement --so it's not surprising that the LS1 economy would suffer.

    The "bodylogicuk" firm, who are offering the kit for the TDV6 conversion, are claiming 38mpg / approx 7.5 L/100km. The torque of the TDV6 in standard form is probably close to the limit anyway of the ZFHP24 transmission. The fact that the P38 is several hundred kg lighter than the L322/20 etc adds to the attractiveness of the package.

    The issue here in Aus. is getting hold of a reliable TDV6 and different sump (from a Jag) plus ancillaries at a reasonable price, to make it all work...

    Good discussion!
    cheers

    Can anyone tell me, the small plastic flares that go around the lip of the guards that I have seen on some p38, are they specific to P38's or are they of a disco 1 and then you cut them as you go?

    For flares ( STC 8514 ) very very rare . Discontinued. Check other thread.

    Hey highrr, I've been telling friends about your Rangie. They want to see pics, (so do I). Any chance you could post some photos?

    Cheers,
