Anybody tried this? Would be an awesome car with a V8 under the bonnet.

 

Just been out measuring the engine bay. V8 will fit as long as the lexus motor is a rear sump variant.

 

Why bother this ? Even if you consider of doing this you should try LS V8 engines

 

Or buy a X308.

 

Would be even more awesome with a V12 under the bonnet.

Oh, hang on.. somebody already did that.

 

Lexus? I think you should put a soft serve ice cream machine in it.

 

You guys get extra points for creativity A++

 

LOL I've just remember why I don't post on forums. It's because as soon as you ask for advice everybody just cuts you down with negative comments!

 

@jakeemom no insult intended but I figure if you can work that particular V8 into your cat more power to ya! BTW it is 1 silky smooth ultra reliable engine.

 

Maybe because you didn't really ask for precise advice, you solicited reaction to your comment 'it would be an awesome car'. Expecting unanimous agreement with such statements on a brand specific board is kind of naive, don't you think?

 

There is really no advantage to shoehorning a Lexus V8 into a XJ40 and then making it run.

If you succeed, then you end up with a Jaguar 4 door sedan with a V8.

It is a far cheaper option to just buy a x308 which is ... a Jaguar 4 door sedan with a V8 that was fully integrated at the factory. No fuss, no muss, just pick which one to buy, pay the money and drive away.

The car will be newer and the total bill will be cheaper.

On a tight budget, buy a broken one and fix it ... it will still be cheaper and easier than a foreign V8, but not as cheap as a running x308 in the end once all costs are totalled up.

 

Try going on a Lexus forum and post that question the other way around (You have a Lexus car with a Jag V8 you want to install in it). I bet you would get a lot snottier comments than you got on this forum. For all intents and purposes that would be an almost impossibly hard task anyhow with almost no discernible benifit. I know they make adapters to put carbureted American V8s in XJ27s, XJ40 has similar underbonnet and undercarriages. This would be much simpler and a properly built (though poorly fuel efficient) carbed Ford or Chervrolet (or Mopar I suppose) engine would be much more powerful and 99% less fuss than making the Lexus V8 live in there.

 

That's the sort of advice I was looking for. Thanks. X308's are not common in New Zealand and Lexus engines are cheap as chips. I can repower my XJ40 for less than 1/4 of the money spent on her already. As a comparison I brought the car for $4000NZD have spent another $5000NZD on it and can get Lexus engine for $1600NZD.

 

we fitted a Lexus V8 into xj40 and x300 bodys in Jaguar in 1995 as i remember its wasn't that hard to do....pretty sure we changed over the full engine harness though....
