Late Jag engine in BGT

[glassman]

Has anyone considered using a late model XK8 or XJ8 V8 in a BGT? Why or why not? They seem small but powerful and look like they would fit.Jaguar seems to be able to make them work well in their large cars.Is there an aftermarket for performance goodies?I'm still leaning toward the small block Ford, T-5, and Jag rearend.Thanks for any and all info and opinions.Connal.

nevr heard of anyone using a jag....might be lots of mods...the fords are good but need mods to crossmember, mounts etc....the rovers pop right in like the one in my pics....easy to find...D&D fabricators actually sells complete turnkey rover V8,s for the mg

Dan B wanted to look at it for his TR7 but since I'll be helping him with it I suggested he stick with the BOPR. Looks like a real good engine, other than the early nikasil cylinders and the cam chain stretch problems. Fairly serious electronics of course. The headers would be a good bit of work. But if you can pull all that off I think it'd make for an exceptional car.

I suspect it's the wiring side of things,as well as the massive costs involved, that puts people off of using more modern engines.

Once you've got around the mechanical issues with the installation you then have multiple ecu's to deal with for controlling the igniton (multi coil packs etc), the fuel injection system, the huge number of sensors needed to control it all and then it all has to be integrated into the B's systems. It will probably cost you more for the ecu's and the wiring than buying and fitting the engine.

This is a sad sign of the future of our hobby as modern donor vehicles become more and more complicated  putting them technologically out of reach of us mere mortals.

I'm guessing there's probably an all-in-one controller either available or in the works. Megasquirt very likely could do it. But in addition to the ign and efi there's vvt and vvl and some of these engines also have variable induction. Iirc the Jag V8 has the vvt and is switchable between two cam profiles for lift. That would mean one output for vvl and probably two for vvt (one for intake and one for exhaust). If one MS can't handle it you could daisy chain a second one to do the job.

One other thing I discovered when looking at this engine.  It is also used in the Lincoln LS, and you can get one of those a lot cheaper than a Jag engine, FWIW.

I was impressed with the output of these engines combined with the economy. Very refined engines. AFAIC, it would be on the short list if I had more to spend on the project.

"This is a sad sign of the future of our hobby as modern donor vehicles become more and more complicated putting them technologically out of reach of us mere mortals." - like some of my favorites - Nissan 3.5 V6, VW W5 or 1.8t, and doesn't get any better (imho) than the BMW "M" 6.

John - I never get bored of seeing your posts; quite the opposite actually /

Have not seen that, but I have a friend who has a TD with an early Jag 6.  Looks like it belongs and I imagine it goes like stink.
He does not drive that way.

Got any pics?  

I'm having a hard time imagining it looking like it belongs.  Not a lot of room for a straight 6.

Does anyone know how much the early Jag 6 weighs compared to an AL buick V8.  Seems to me that it is a lot.

[MGBV8]

Cool pics.  I just can't see that fitting in a T-Series.

IIRC the early Jag inline 6 comes in at around 600+ pounds, a real hunk. If you notch the firewall there is really a lot of length in the T series hood, almost half of it covers the foot wells, so if the engine is narrow there's more room that it would seem and still have room for the driver's feet and controls. I'd love to see photos of that swap though.
