i have a 95 xj6 and want more power got $5000 saved up so far.

but have not been able to find any info on supercharging or turboing the xj6 motor.

or if possible swap out the xj6 for the xjr engine and ecu.

any info on would help greatly

 

jth, I can't speak directly about the XJ6 engine, but if you do this mod, one of the big things that I would ensure you do is knock the compression down on the engine to a more manageable number like 8.5:1 or 9.0:1. If you go with the stock 10.3:1, you are going to be requiring some fairly special gas and it will make driving the car no fun due to the cost.

I guess the other thing that I would look at is how much power you are shooting for. I would start with that number and that will then dictate the amount of power you can realistically get out of a motor on a budget. As long as you are sticking under 400 hp, then the XJ6 engine should do you good and should be a reliable engine. More than that, be looking at the XJR's V8.

Granted, I would be looking at spending a bit of money on porting/polishing the intake/heads. You can open up some more power and even with a mild supercharger, obtain the power numbers you are looking for. By using a smaller supercharger, you are more likely to remain on pump gas.

 

It would be far less expensive to just buy a 95-97 XJR. It will have the stronger transmission and proper engine management. It would also be factory, so repairs are by the book instead a "where do we start now?" with every repair.

 

As Ken mentioned just buy a XJR. Why would you want to sink $5,000 + into a $2,000 - $3,000 car?

 

get a 95 xjr avoid the 96-97 my ,my opinion stay with the xj6

 

I would sell your XJ-6 and buy a 98-99 XJR. Very Cheap Money now. The below will cost 1,800 bucks. Take the 3,200 you saved and get a new paint job?

They have 370HP stock in the 4.0L.

Immediatly do a Transmission Service from Euro. Get a Pulley Upgrade. Take the Screens out prior to the Cat, and if You know of an inspection station, take the cats out and hollow/core them, Denso Plugs, and oh yes always Super Unleaded and synthetic. Put a cat back Mina exhaust and Cold Air Intake and wammo you have 410hp and 0-130mph never was so much fun.

That is what I did and all is Good
