I want more power, and I have a few ideas. Not sure if this has been brought up here in detail, but...

1. Is a small turbo impossible for the X-Type? I'm talking <=260 HP.
2. Would it be cheaper to buythe more powerful3.0L from theS-Type (if possible).

Have at it guys. Waiting on input.

 

I think that quite a few people have kicked this idea around before and it always gets back to a weak, fragile drive train, not so beefy transfer case, and the fact that its 40/60 for power front to rear. anyone else can chime in, but I think that was the answer some of the smarter members came up with. think you should just get the s-type-R.

Throw in a K&N filter, use synthetic oil and get a cat back exhaust system...You be money ahead and it will sound cool too.

 

3.0 S-Type = 3.0 X-Type... same engine.

I know there was a guy here that seriously looked into getting power out of his X, which was Racer. However, when I arrived, he left shortly thereafter, so back to the drawing board for info.

The 2.5L V6 in the Jaguar is very similar to the Duratec 2.5L V6, correct? The Duratec V6 can be turbo'd, so can one assume that the X can get the same treatment?

Again, I'm not talking about doing anything extreme. <= 260HP. I'm not engineer, but if the X can handle 240HP from the 3.0L, 20 more HP shouldn't hurt

I'm seriously taking this into consideration. If it can be done for 3500 or less, I'm up for the challenge.

 

Spartan, you can get an extra say 20 hp out of the motor easily for under $3500. The issue that you are going to have is that the transfer case is going to give up the ghost a lot sooner unless work is done to it too. Are we talking about it failing in 1,000 miles in stock condition? Probably not. Within 20K miles? Odds are significantly higher. So, you have to ask yourself, money now, money later? The motor will handle the additional power easily. Getting the power is fairly easy to obtain too. But, look at the weak link, the transfer case. You want reliability, that is where your focus should be.

^ I see your point. However, thetransfer casecan handle 231HP. Will a 12% increase from 231HP kill the transfer case? I'm not sure, but I doubt it.

I use that number because the 3L is rated at 231 HP and the current transfer case handles that just fine. I have the 2.5L, and a bump up to 260 HP would be a 34% increase for my car, which is significant. I'd pay good money for that because I think it'd be worth it, considering that I plan on keeping the car for a while since it's nearly paid for.

 

It all depends on how you drive your car. If you like to launch with the AWD, andincreased horsepower the wear and tear on your powertrain will be significant. If you want a good ammount of HP increase I would keep the power to the highway to increase reliability. Id beta transfer case could handle a 12% HP increase as long as you dont floor it at every green light.

 

Spartan, all that you can do is try it and see what happens. I have done a lot to my truck that most people thought would drop it to its knees. But, I accept the fact that things are going to wear a bit faster. But, I am getting the look/function that I want out of the truck. But, I figure if you can get a better set of gears in the transfer case, then that would allow you to get more power from the car reliably. The big trick is finding an upgraded set of gears. Granted, part of it might just involve getting a second transfer case and giving it to a metalurgical shop and let them heat treat the gears to improve their strength.

The options are only limited by what you can afford and what you are willing to do. Getting the gears heat treated should be fairly cheap. But, most of the cost will be in pulling apart the transfer case and getting it in/out of the car. Granted, you can probably also talk with a machine shop and if you give them the gears from out of the stock transfer case, they can machine up some new gears for you out of much stronger material. Then you are golden. But, this is one of the more expensive routes (about $500 for the gears more than likely, then add in disassembly/assembly).

I'm more than willing to try it, however I don't know where to start in order to acquire a turbo and everything else to go along with it. I dont want a huge turbo that requires a intercooler. If I can get started and get it installed, maybe I'll be the first to actually have a turbo install on the X-Type for all the world to see.

 

That sounds a brill idea Spartan

 

let me say this one time...ARDEN,nuff said. good luck, Bill

 

i was looking to do the same thing, but my brother talked me out of it. i could spend about 600 on exhuast, about 200 on a cold air intake or short ram, and another 150 on a performance chip plus installation fees. so thats about1000 dollars for UP TO 30 to 40 hp gain. considering i already have 230 in my 02 xtype 3.0 awd,my brother convinced me it wasnt even worth it to jump up to MAYBE 265 ish. its not like your going to be beating any camaros or anything like that. id say, save your money its not worth it. maybe just wait until theres a supercharger for jag. that way, youd be adding more like 100 hp for 3000 bucks. more worth it for the jump up to 330 ish. i wish it was all cheaper...

 

It'd be worth it to me, because I love my car I'm not out to beat up on other cars, I just want more power. It was easy with my Prelude becase even though the aftermarket wasn't huge for the Lude, when I wanted headers, CAI, exhaust, and eventually a turbo, it was easy for me to gather everything I needed.

This car on the other hand, not so much. I didn't think I'd be getting back into toying around with cars as much, which is one of the reasons I bought the X, but it looks like I want to go where no one has gone before...

 

I also have a 2.5L and would like a bit more horsepower. some people mentioned a catback exhaust? For someone that is non mechanical, does that mean just replacing the rear muffers such as borla's? or do you have to replace all of the exhaust system even the headers for some gains in HP?

thanks!

 

hankdycbr, when someone talks about a cat back exhaust upgrade, what they are referring to is replacing the exhaust system from the catalytic converters to the tail pipe. So, you are replacing about 75% of the exhaust system. As for gains, it all depends on what type of system you get and the style of muffler you go with. Yo ucan probably get about 15-25 hp gain from a decent cat back system.

Exhaust will be one of the first mods I get done. Hopefully once I get out of here (Army Officer Candidate School) and I get some freedom again, I'll be able to get that done.

Also, I know this may be a bit much, but can the 2.5L engine be bored/stroked? I'm sure that would yield more power.

 

THanks THermo for the great explanation.
I will keep that in mind!

 

Hanky, just to make sure that I am clear on what I am saying with the cat back exhaust setup. They don't replace your catalytic converters. You replace everything downstream of them. now, if you are looking for a bit more bang, then you can swap out the headers (between the engine and the cats) and put in some high flow cats and then you will get more. But, at the same time, you are looking at twice the cost, if not more. But, going with a set of long tube headers will give you more low end torque which will help with the line launches while still giving you more top end power.
