Hi all - I’ve been lurking jag-lovers (and other forums with information on the 5.3 & 6.0 V12s) for a long time.
Earlier this month I took the plunge and bought a pair of Jaguar V12s in a package deal. One is a 1989 5.3L (engine number 8S61922SA) out of an XJS (VIN SAJNA5844KC154124). The other is a 6.0L (engine number 8C13879SA) out of an XJ12, but I don’t know the exact model year.
I also have a 4-speed from VIN SAJMX1345…(the VIN sticker is scratched up and hard to read) which is from yet another car.
Can anyone shed light on the specific model year of the 6.0L, based on the engine number?
It has the Marelli ‘gutless’ distributor (so it’s not the final hoo-ray with the Nippon distributor-less system. I haven’t opened it up yet to see if it has the cast or forged crank, but my understanding is that the 6.0L oscillated between cast and forged in the final few years for the US market. Any other identification tips would be welcome.
My plans are to get the 6.0L up and running and mate it to the 4-speed. I don’t own a Jaguar vehicle, so I’m not sure what the plan is once the engine and transmission are functional. (I’ve seen lots of great projects with V12 swaps here and elsewhere.) Right now the Electromotive TEC gt200 is the leading candidate for the ECM and the PCS Simple Shift for the TCU. (MegaSquirt and the Bosch MS 6.1 ECU are darkhorse candidates in the ECU race, also.) I’ll be going distributor-less and transitioning to high impedance Bosch EV6 injectors that are drop-in replacements to the OE units.
One question that presented itself early on is: What type of fittings attach to the fuel lines? It looks like a hybrid -AN fitting and GM push-to-connect fitting. Can the OE lines be replaces up to the rail with something more readily available in the aftermarket?
I have a small list of parts that I need. I’ll post these to the WTB forum shortly, but since this is V12 specific, I thought I’d post them here, too.
- Full-flow oil filter housing (it was missing from the motor when I got it.) (Jaguar Part Number EBC8361 is the entire assembly; also need Outlet Elbow EAC6789.)
- Water pump - The pump on the 6L motor was cracked like water froze inside of it, or the pulley got hit really hard from the front left corner of the car. Anyway, I need a replacement pump (Jaguar Part Number JLM10648) and gasket set.
- Camshaft oil feed lines (Jaguar Part Number EBC8755), banjo bolts, and banjo adapter stand (Jagur Part Number C42072). I have 2 oil feed lines for a 5.3L, but none for the 6.0L. (The Rob Beere replacement looks great, but is a little steep for a salvage motor.) I need all 4 banjo bolts (one for the engine block, one to the tower, and two for the cam housings), the formed lines (EBC8755), and the casting (C42072) that mounts to the cylinder block top (‘valley’) cover.
- Coolant balance tube across the front of the engine - the one on the engine was rusted through in a couple of spots.
- The cast aluminum dust cover (access plate) between the engine and the transmission.
The 5.3L suffered the all-to-common injector fire, but it seems like it was caught fairly quickly. The distributor is toast, the intake manifolds, air injection, and fuel injection rails, and associated parts are gone as is the water pump. It has an air injection pump and most other brackets, but no other accessories. I’ll be selling it as-is or parting it out (or sending it to the scrap heap) depending on who needs what.
I’ll try to post a picture in the next few days.
Off the top of my head, I have a spare cam oil feed line for the 5.3; a spare valley cover that is painted black; the air injection rails, pump and line from the 6.0.
Thanks for taking the time to read my post. Look forward to learning from everyone.
