Hi all
I am looking for an 1998-99 AJ26s or AJ27s Motor to rebuild,
to replace my XJ 1998 3.2L motor running perfectly
why you ask, well it the Hp issue
thanks Dutchy

 

Installing a SuperCharged engine in your car will have LESS power than a Normally Aspirated because of the lower compression ratio. A Normally Aspirated engine is really what you need.

This was the info I was going off
hence the decesion to replace the whole engine and g/box t, to uphrade from240hp to 375
is this info incorrect?
Supercharged

The supercharged version of the AJ26 is used in the high-performance R versions of Jaguar's cars. The engine was updated with AJ27 specifications for 2000. It produces 375 hp (280 kW) and 387 lb·ft (525 N·m) with the help of an Eaton supercharger (modified roots-blower). The supercharged engine did not use variable cam timing as the normal benefits of improved volumetric efficiency are not noticeable on a boosted engine

Vehicles using the supercharged version include:

AJ26S

1998-1999 Jaguar XJR

1998-1999 Jaguar XKR

1998-1999 Daimler Super V8

 

There's more to consider than just the motor. Management systems for motor and gearbox for one and no doubt a host of others.

 

If you're asking for advice on the swap then this is the place to post the questions.

If you're advertising "Wanted to Buy" then it should be in CLASSIFIEDS forum.

It would be far easier to simply purchase an X300 or X308 with the AJ-V8 already installed.

 

Thanks grahme for the highlited Classifieds
but if you have been reading what I have been trying to find out
as I have no knowledge of the jag engines
you will see that I have talked about changing crank (for longer stroke)
about the VVT not on the AJ26S and the AJ26 and using my heads with a M112 charger.
Flex plates ect whith out all the ecu hassels
it lead me to maybe it was just easier to fine a 1998 4.0L supercharged But! very scarce
so yes maybe look for a 98-99 XJR or XKR motor and box
thats the next step in the CLASSIFIEDS
Thanks

 

thans mate I will do that
regards Dutchy (John)

 

The ONLY way I see to accomplish what you want would be to get a salvage XKR and transfer ALL the necessary components (parts, harnesses, modules et cetera).

You will be FOREVER looking in salvage yards and on the internet for 'JUST THAT ONE MORE PART' to TRY to get it running correctly.

Good Luck

Bob I have found an early 4.0 AJ V8 N/A XK8
complete engine & transmission with harness & computers, (whatever that is required)
a supercharger could be fitted the guy says
what do you think

 

What central coast are you on?

 

Not that simple. Basic structure is the same but many differences in the detail. Jag also went to different gearbox for the blown motor and they didn't do that for the fun of it.

wondering why supercharger pulley has been removed.

 

Thanks Baxtor
I know they fitted the merc box due to extra power
can you tell me some of the differences pls

 

I live on the central coast Australia New South Wales Killarney Vale
thanks dsnyder586

 

as far as I can understand from the email it never had a supercharger fitted
the wreckers are asking 5.5k not sure what sort of price I should pay
or if they are including fitting, I am waiting email from them
thanks again

 

You misunderstood Dutchy, l was referring to the Craigs list advert.
On the differences between SC and NA engines it may be easier to Google but vvt, comp ratio, SC drive and engine management are a few that come immediately to mind.

 

sorry missunderstood
Thanks for you help

 

thankyou price is better
not sure if a 2001 is compatible with my 1998 x100
