I have an engine swap question

If our V8 engines are based on a Jaguar design would it be possible or feasible to install the F-Type R engine in the V8 vantages? Would the mount points be the same? Seems if so, that makes far more sense than supercharging the existing engines or a Chevy swap that has been done. I saw a rebuilt Stage 2 build for sale for only $11K!

What about the oil sump in AJV8?

Isn’t someone working on using the supercharger from the Jag on a V8V?

I believe the Jaguar engine swap would work. Nobody has the ba## to take a perfectly good engine out and try it. (Yet)
if my engine ever went belly up I definitely would be interested.

Isn't the Jag engine direct injection? That would be a major hurdle to overcome unless the heads and intake are a direct swap.

Get the engine and all the associated necessary parts from a junk yard. This is what engine swappers have done for years.

I think the 5.0 liter engines are and 4.2's are not.

The Aston V8 is "based" on the Jaguar V8, but... As brightoncorgi said, that base is the 4.2, not the 5.0 that is in the F-type. Also, the Aston engine was comprehensively re-engineered -- it has its own, unique-to-Aston block, crank, conrods, pistons, rings, bearings, heads, cams, valves, etc. It has a dry sump, whereas the F-type has a wet sump. The Aston uses a torque-tube and a transaxle, whereas the F-type transmission bolts directly to the engine. Essentially, there is nothing shared between the two. I don't know whether the F-type engine would fit, but I'm guessing it would't be easy.

Just by looking on a few engine pics in the net, the oil sump seems the indeed the biggest hurdle.
On the AM Engine, the flange for the bellhousing is the lowest spot, where the Jag oilsump protudes significantly further down.
So it may be possible to swap the engine, but ground clearance may be compromized (as is tight on the Vantage already).

I think the only advantage you might have is bellhousing compatibility. Looking at the two, they look similar, though not identical. Dowels and most of the bolts at least look similar though, and I don't see why they'd change them without a good reason.

That leaves:

Custom clutch
Custom sump/clearance
Engine management/chassis integration
Fuel system
Cooling system

That's a lot of work. I think I'm one of very few people (maybe just me and Craig from Dynotorque) that have done any type of engine swap in an Aston and kept OEM functionality (factory gauges, ABS, HVAC, etc). If you actually went forward with something like this, I have the CAN data to run the stock gauges and manage warning lights for ABS/TCS/etc. I'm putting a MoTeC on my engine which will integrate to run the OEM bits as well as manage traction control, etc.

FWIW, if you were paying a shop to do this, you're probably $10-15K dollars + parts, maybe more. My swap cost upwards of 30K in parts, no labor. A Jag supercharged v8 would probably cost somewhat less, but I'd wager you'd still be in $30-35K in parts/labor, unless you're doing it all yourself.

edit: Better engine management and turbos or a supercharger on the 4.3/4.7 make more sense. None of it makes as much sense as selling it and buying a V12 probably. You'll likely be money ahead doing that. I could definitely have a nice V12 for what I have my V8V, but I'll have 200 more HP than a V12 and I like to mess with stuff because I'm not right in the head.

Given the complexity outside of frame mounting points, such as control units, integration with the rest of the systems (BCM, etc), dynamics of the rest of the powertrain (axles, differential, etc), I'd say you're better off selling the V8V and buying an F-Type R. Everything works and is designed together, newer electronics, newer interior, faster car, etc. You're also trading the "cheapest" Aston sports car for the "most expensive" Jaguar sports car. I'd say it's a good trade and MUCH less headache. And the F Types are gorgeous to look at as well.

Or if you absolutely love the Vantage (yes, they're beautiful), then go back to the V12

If you were to acquire a supercharged Jaguar engine I say got for it. Cost has never been the overriding factor in determining what the heart wants. (smile)
