Ford i6 into Jag?

carls*world — Sun, 14 Oct 2012 12:17:29 GMT

Anyone heard of this being done before? Just an idea I'm toying with, I have a sweet running 4.0MPFI with 4 speed auto out of an EL, just sitting around looking pretty, looms, ECUs, the lot, and the possibility of a very cheap XJ6 with a very shagged 4.2 motor.

NO... not at all interested in spending a couple of grand copying the oh so tired textbook and ramming a 308 or 350 into it, so let's not go there 😛

The motors seem, outwardly, similar in size and shape. I'm thinking if anything, the Ford donk might stand a couple of inches too tall, but could be just an illusion. Naturally mountings would need to be fabricated. Just wondering if anyone knows of the transplant being done (or tried) anywhere before?

ive heard of it with a toyota straight six conversion http://writeonmotoring.com/features/japanese-jaguar

the jag six is a huge old thing, room shouldnt be a problem.

If you can marry the Jag borg warner/ turbo300? gearbox to the ford engine without modifying the rr cross member then engineering will be easier.

My problem with any conversion using eb ed ef el 6s is the difficulty/frequency in doing headgaskets (with the stalky bit that comes up through) the inlet manifold, and the difficulty in access to the dizzy.

(these can be alleviated by fitting an aftermarket sensor lower in the coolant flow and using a set of "rule" dumb dumb auto cut out gauges. These can be fitted and calibrated so that the engine cuts out before a critical temperature or lapse in oil pressure occurs)

Basically the temperature senders are positioned too high on the head at the rr of the engine. There is a bypass hose at the rr when/if this hose fails an extremely small coolant temp rise is evident however as soon as the coolant leaks enough so that gas/steam rather than coolant is touching the sensor then the actual coolant temp is not recorded and returns to normal...sometimes cooler than normal.

Hence the sad sad story I have heard many many times from customers upon inquisition

"nup no temp rise....there was just this rubber burning smell and a clatter bang, then steam..... and it stopped.....waddya mean seized?? are you sure it is the headgasket??....are you sure that the rings are now soft???..."

yup,yup and yup

*should be*

Thanks so far guys. I don't hold much fear about heads/gaskets. Only trouble I've had in that respect so far is my own fault running insufficient coolant, just topping up too much with water and having a head eaten away behind #6.

Good thought there re using the standard box, though 4 speed would be nicer for cruising speeds. Most B/Ws run a common case to bellhousing pattern, so that might just work using an earlier 35/40 bellhousing. Something worth investigating.

Could even retro things further...... the Jag is a S2, carby model, so maybe an EA CFI manifold, + XF Weber (or aftermarket 4BBL?) and early dizzy. Would complicate wiring a lot less. Rid the setup of all computer nonsense then.

Though the bottom line is using what I have already available, keeping costs down.

Too late.

It's sold. 😐

a pity, it might have been a good project.

maybe try a different project, imagine how well this would go with ford power. ;\

:^O

Reworked Willy's??

I'd have thought more like a reworked German V2 TBH

Now...... where to raise a few more bucks. Spotted a quite tidy XJ40 with head problems for $1200

i think i put the wrong description next to that pic, the willys is on the bottom of the page . i dont mind it actually.

the other is a belly-tank contraption . 25mph was probably hair-raising enough .the XJ40 might be a bit heavier than the series 1 or 2 XJ6 , a real luxo-barge..:-)

Ahhh that's better. See, 100mpg was possible, even back then. Wonder how it'd go with a 4.5HP B/S out of a Scott Bonnar?

the XJ40 might be a bit heavier than the series 1 or 2 XJ6 , a real luxo-barge..

That's what I want. Not concerned too much with sporty handling, or lively go. Happy to be floating along oblivious to the world around me.

Hang on.... you need a Volvo for that last line.

:^O my friend had one (XJ40) they handle pretty well if i remember correctly. the problems i remember him having were electrical, things like warning lights constantly telling you it was low on oil and other things when it wasn't. he found it nerve racking .

I just bought Dort No2 a Daihatsu Mira j with a massive 660cc 3 cylinder fuel injected engine 145/60/12 tyres (think wheelbarrow) have been replaced with 155/80/12 tyres and the fuel economy has gone from 400kms per 30 litres to 450 (bumpy) kms per 30 litres

Guess the Ford motor would suit it well. Wouldn't feel out of place, my EL tells me coolant is low when it's not, oil pressure all over the place (goes off the scale at the top end at times) etc.

If you remove the low coolant sensor from the header tank and clean it, it should function correctly once it's refitted.
