700bhp in a 7??? Do you have a nice CD collection? I'm after a decent stereo too. If you have any of these, can you change your will and
I'll come and pick them up the day after you pass the SVA.
Cheers,
Jon

Like the essex v6 these engines breathe very poorly giving poor power and fuel economy but good torque. They both overcome this airflow problem when
super - or turbo charged. An essex with low boost can easily push out a reliable 230. Fuel economy doesn't worsen (it is bad enough before!).
If you can machine up a pair of xj6 twin cam heads to fit you should be able to make much better power and improve fuel economy. Although not the same
engine, the XJ13 engine used twin cam heads and made an easy 500 hp.
If at first you don't succeed, hide all evidence you ever tried!

Then add another couple of cylinders lengthways, and a bit widthways. Will you be running the steering column though a hollow crank
BTW, I'm all for it

I can fit my straight 6 in with plenty of room width ways and about 2 inches to spare length ways. Is yours a locost? I have based mine on
chrisg's book so it will be a bit wider than a standard locost. The problem i have is that i only have room for one engine (in the garage ) so
i cant look for a cheap one and sell it if it doesnt fit. I need to be pretty sure.

A quick Google later
Jaguar 5.3 V12, 680lb fully dressed for installation, + heavy GM400 box ~200lb(not the light BW66 in early cars), I guess you will be looking at 850lb
all in !
You will also need to keep this lump cool.
Not that I,m against the idea which is why I ran a V12 jag for a while, but I do think you will need to use as much of the donor as possible, complete
drive train, front hubs (they are double wishbone so you can junk the heavy Jag arms) so should consider lifting the body from the car and building a
chassis and suspension around the components, not customise what you have started.

Whilst I am no expert on building kit cars !! I know a fair bit about Jaguar. The v12 engine is one of the best they have produced. DO NOT repeat DO
NOT fit a 4.0 V8 S/C XJR engine or early super V8 these cars were produced 97/98 onwards. They suffer terrible compression problems relating in part
to Nickersil bore linings. Symptoms were poor starting and what became known as "V8 engine stall" Thousands of engines were replaced under
warranty ! Not just by Jaguar. BMW also suffered similar problems with 7 series. The performane is awesome but for reliability I would look for an
early 6cylinder XJR engine with Manual gearbox. These are found in 94 onward X300 models.

Yeah based on RC's book, but chassis is PLUS 4", which means your chassis will only be a couple of inches wider (including engine
compartment.
Maybe you should buy a Viento chassis
NS - Cheers. Will be happy when it's going

The V8 engines were built with steel linered engines from 2001. Iv got the VIN numbers at home but so long as it will fit, i think the V12 will be
what i go for (god i hope it fits ). I was originally going to go for a 4.0 supercharged straight 6 which is why i build the chassis with a bigger
engine bay.
Simon - the viento chassis is definatly an option if it doesnt fit but i really wanted to have a 'scratch built' car. Il see how it goes.
I think it might be worth looking past that just to have a V12 lump

I always thought the V12 was cast iron. Are you sure it's aluminium? 300+ kgs seems pretty heavy for an all-aluminium engine. Isn't the
Rover V8 about 160 ~ 180 ish?

While wikipedia isn't always completely accurate people tend to correct stuff like that pretty quickly.
