  1. Hey guys. I’m throwing around some options for my 87 EFI XF S Pack which needs some work (engine issues). From what I see, I have 4 options with it and I would like to get your feedback/ideas. To preface the options, I would like to use this as a bit of a fun car, do a few hill climb events, some track days and so on. It cost me next to nothing to buy so I don’t want to spend huge $$, think of it as a budget racecar. Plan to build it up over time, so want to pick one direction and evolve it. So the options as I see it are as follows: 1. Ditch the 4.1 and put in a 5.0L Windsor. Benefits- V8 (huge benefit), legal, fits and will work with the 4 Speed Single Rail Costs- Back to a second hand engine (could have issues like the current one), will be hard on the driveline 2. Fix the CrossFlow Benefits- Origional Numbers etc etc however I hardly think a XF will every be worth anything and this one is still in very average nick inside. Probably easiest option and I can learn how to do it myself. Costs- It’s still a 250 Crossflow EFI. You can’t do much with them due to the EFI system so they are what they are. 3. Fix the Crossflow and convert to Carbie Benefits- Interesting option, can run a huge cam and, from what I’ve read, create good power with some minor adjustments and a good Carbie. Costs- Illegal, mine is a 87 Model so has the pollution control gear. Supposed to have a cat as well (I think that went a few owners ago), however who’s going to pull you over and check?? 4. Convert to 4.0 SOHC. Benefits: Cheap motor, makes more power than a crossflow, can be chipped easily, cammed easily and will fit straight in. Cheap too! Costs: Never done an engine swap so could be interesting. Probably won’t marry to the Single rail so will be up for a gearbox too (but a T5 conversion wouldn’t be a bad thing). Would like some opinions or throw some more options at me! Cheers Steve Sent from my iPhone using Tapatalk
  2. Thanks for the encouragement Gents. Took the first steps today. Thought it would be easiest to eliminate the easy things first, so have removed the Intake, Plenum chamber and rocker cover. Have removed the rockers and checked the rods to ensure it’s not a bent rod (it’s not). Some observations so far. It’s unnecessarily complex isn’t it, the Vacuum set up from the rocker cover. Took heaps of pics but much of it could be simplified. The head (from the top) looks great, no buildup of gunk or anything else on the inside of the rocker cover or on the top of the head. I ran an oil flush through it before changing the oil and it seems to have done its job. The prior owner had done a bit of work to it from time to time, fiddled with it a bit. However I’m not sure whether he put it back together well. About 1/2 the bolts on the rocker cover weren’t even finger tight. Maybe the issue is just a vacuum leak from the Rocker Cover? The Charcol Canister line is full of oil. Must be a bit of blowby in the engine, maybe a complete strip and rebuild is on the cards? I’ll keep going, planning to remove the head completely and get to the lifters next. Hopefully it’s just a dodgy lifter and not a cam lobe? Sent from my iPhone using Tapatalk
  3. Hey guys! So I want to chip my XF EFI Manual and I am told a J3 won’t be compatiable with the XF ECU. So I have a EL ECU and complete wiring loom. As I understand it, I can connect a few inputs only to the EL ECU and then instal a J3 chip and tune it a little more aggressively. My question is, what inputs need to go where? When I bypass the XF ecu for the above, can I continue using the XF ECU and loom for the balance? Thanks Sent from my iPhone using Tapatalk
  4. Thanks mate. Alt exciter wire worked a treat! Sent from my iPhone using Tapatalk
  5. Thanks for the tip. My biggest issue is that I’m not all that confident pulling the engine out myself and it’s expensive as anything to have someone do it for me (been quoted $1700 for removal and install). Sent from my iPhone using Tapatalk
  6. Hi all! Now I have had an issue with my XF Falcon not idling correctly. I have been able to diagnose it to a crook camshaft after having a play with a dial guage (courtesy of EBay of course). So now I have a choice that I was hoping a 4.1 (EFI) guru could help me make. I have spoken to Crow Cams and they have recommended a Street/Speedway Cam for me which cool. I have a Haynes (online) subscription to the XF Manual which states that the cam can be replaced with the engine in the car. My question is twofold: Firstly, for a relative novice, how hard is it to replace the cam in a 4.1 EFI and get it running again and.... I understand that you can replace the Valve Springs with the head in. Considering the cam has probably been dodgy for a while, would I be better off pulling the head while I’m at it and getting a valve grind etc etc before reinstalling the cam? Any advice or tricks would be appreciated! Sent from my iPhone using Tapatalk
  7. Hi Guys, I’m looking to make my XF S Pack into a bit of a hill climb/track day car and I’m looking at seat options. The drivers seat is a little tired, not supportive and, frankly, uncomfortable. I was wondering how easy it is to fit, say, a set of SAAS or similar seats to the XF? Any advice would be appreciated.

  8. Hi all! I have a 4.1 EFI in a XF SPack and it hunts at idle. Alternates between 500 and 1000 RPM constantly. Have you got any ideas on what to look for with this? Thanks Steve Sent from my iPhone using Tapatalk
  9. Hey all! I’m converting my XF Falcon to twin electric thermos. I’m looking for an (easy) ignition pickup for the relay on the battery side of the engine bay (traditionally I use the positive on the coil, but seems a long way to go). Any good ideas? Sent from my iPhone using Tapatalk
  10. Yes the gold looks awesome. The black will look better with a white car though Sent from my iPhone using Tapatalk
  11. So decided to take the plunge on a new set of alloys. Picked these, I figured they will be more in keeping with the age of the vehicle! Sent from my iPhone using Tapatalk
  12. Yup. Definitely not a XF Wheel! Lol Sent from my iPhone using Tapatalk
  13. Hi mate. It’s the ones it came with. 17x 8.5’s below. I would suggest they never fit properly! Lol Sent from my iPhone using Tapatalk
  14. Cheers Gents I’ve never been keen on spacers either. Going to go with the new Alloys. Will try some 17x7.5 which should fix the issue Sent from my iPhone using Tapatalk
  15. I was more thinking something like this: I think I’ll have to roll the guards whichever way I go Sent from my iPhone using Tapatalk
