I wrote a thread on this a while back and I was thinking of going this way with the VL, since Holden make a good engine now (my granddad has got 271,000 kms out of his VZ without a problem), though stretched timing chains are to a VZ as what cracked heads were to the Nissan RB30 in the VL, I've never cracked a head on an RB30.
Wrecks of VZ's seem to be cropping up everywhere but most are automatic , here's a basic run down of what would be needed to put even the 175kw motor in, I think that would fly in a VL, someone has fitted one of these motors to a VL Calais so it's not an original swap :-
- AY6 Aisin Warner 6 speed transmission (if I could find one), probably could find one out of a Lexus IS200 or something at the Japanese wreckers.
- Standard 3.45:1 VL Commodore diff fitted with LSD centre (preferrably 4 pinion), if fitting the 6 speed manual.
- Modified front tailshaft (to mate up to 6 speed manual)
- Headers modified to couple up to the VL's 2.5 inch exhaust system
- adjustable fuel pressure regulator fitted under the car (Tee'd off to tank) , VZ system is a non- return type.
- Splice all the wiring & loom into the existing VL's wiring (same as I did with the R33 electrics)
- Speedo adapter (to run Alloytec computer & standard VL dash)
All of the parts including the fly by wire throttle will come with the donor car, if I didn't fit the manual and stuck with the 4 speed auto, the things I would probably have to change are :-
Front tailshaft section, one from a VN - VS automatic Commodore would probably fit and the TH700R yoke should fit that transmission.
3.08:1 diff gears, probably would try to chase up a VK-VL V8 diff, the yoke probably could be changed over on the VK diff unless the splines are different, there is a lot of variation in the Salisbury's in the Commodores.
I was looking at Dellow or CRS (CRS have gone into receivership) for a conversion kit to fit a Toyota 5 speed to the Alloytec but the most they do is up the ECOTEC and Holden V8 (Not LS1) ,probably could use the auto bell housing off the Alloytec and make something up from that.
Yeah, I've probably have to make something up myself.
