so im in the middel of rebilding my jaguar xj 5.0 (non supecharge) and i found somting un bilivable.
my car 5 yers ago had an engine chance.
dont know the resone.
as i puld the block out i fine thet the number on it 9w83-6L074-AB is infect a supercharge angine that came out of land rover lr4 supercharge (508ps engine)
i chackd the chylinders and see the they are flat as the supecharge car has.

so what i have is a supercharge engine whit no supecharger.
so cuple of questions for you:
how bad is it? can the car run normaly like this? as a regular 5L xj? the only thing i see a difrent is the chilynders.
and for the milion dolor questian.
except from buying supercharger.and a new belt. is there any thing else i need to replace for the car to transform to supercharge car? like engine computer?

 

Car will run fine but will be low on power as the compression ratio is less.
Don't know about the rest but I would think so?
Don't forget about all the inter cooler stuff on the engine and the front mounted radiator too. I think it would be a lot of work.

But very interesting that someone did that.

so as i know the compression ration is
supercharge: 9.5
N/a: 11.5
How bad is it?
how mach power will i loss?
feul consaption will be efected?

 

Yes you will have less power and burn more gas but it won't be a huge difference.
What was your gas mileage before your engine problem happened?

Unless you can drive another NA XJ back to back with yours I don't think you will be able to tell the difference?

so im very interested of what i need to change to make it a supercharge engine again.
i cant tell what supercharg will fit my engine.
i know it was aland rover 508ps engine number: 9w83-6L074-AB
i see online all kine of diffrent superchargers.

LR096455:

OR AJ813785:


as well i need:
intercoller whit all hoses
ecu modue
engine wiring harnes
and i think thats all?
can some one tell me if i miss somthing?

all oder parts are the same?
oil pump?
feul pump?

 

One difference is the SC bypass control changed from vacuum to electronic around 2014 (Note LR might be different?). What year is the LR engine? Make sure the type/year of bypass matches the ECU. The picture you have above has the electronic bypass control. Also this will get messy! Do you have and do you know how to use SDD? This is the factory Jaguar diagnostic/programming software. It will be required when your in this deep.

You are way ahead of me so I hope someone like Cambo or Xdave will jump in with more details? Yes it can be done but I would think hard about if you want to do this. The cars have fallen in price so far at this time I would recommend just getting a SC version if that's what you want?

Note you have the very early 5.0L and those tend to have timing tensioner problems. Has yours been replaced? Of course we don't know if just your block was changed or the entire short block with heads/cams was changed too? Have you checked the part number on the heads? Do they match the year/model of the block?

Adding everything you would need to make it work properly is opening a can of worms. The supercharger is the easy part. Everything else - the electronics, control modules, configuration files, wiring, etc. - will take many hours to get right. And what if you can't? So, the question is whether the benefits are worth the costs in parts and time. And aggravation.

Or are you better off to save your money and drive it the way it is, instead of venturing into the unknown? Or trading it for a proper supercharged XJ?

It's your car, your money, your time, and your choice. Spend a little time evaluating this project before you decide.

I'm also active on the X150 Forum (2007 - 2015 XK/XKR). In a similar situation, a member working in Oman wanted to convert his LHD XKR to RHD. He decided to sell it and buy a RHD XKR upon his return to the UK. He chose the easy way. And preserved his sanity.

I can't believe you can rebuild an engine, but don't know about spell check....go figure

 

I don't get it, so many people put superchargers on their cars, but adding one to a car that can be had with one, and it's mission impossible, I would think that this would be an easy job, just add the things you need, and change the ecu, what am I missing?

Sorry about that.I usually post from the mobile when I'm all covered in oil and my English is not the best.(That one I did use spell check and had only 2 mistakes), I'm getting better ill try to use it more.

 

I can't believe you don't realize that English isn't his primary language. Nevertheless, I had no problem understanding what he was saying and so did everyone else in this thread except you. Go figure.

Must be why you're Grizzley.

 

It is...

That is a totally unacceptable response to Udiasi whose first language is clearly not English but has managed to describe a technical issue clearly and then to Stuart S who is a Veteran Member for criticising you.

If you can't contribute anything other than being BOORISH, CRASS and RUDE, don't bother coming back.
