mods for jaguar s-type

[Rcoug]

What mods will be need to put a jaguar s-type in my 1999 MTX V6 cougar??


thank you

it really wouldnt fit.. the stype tranny is a RWD tranny, so if you were to put ont int he cougar, the tranny would probably be sticking out the driver side of the car :)

[NorCalCoug]

I think he means just the motor, which is why he mentioned which tranny he had. ;)

[ov3n]

for some reason i could swear he asked if the tranny would fit the cougar. my bad.
i guess the ENGINE may fit with mods.

[pythagoras]

which motor im gonna guess the 3.l and not the 4l
thats the smallest one in the s type
if not wanna swap engines

[Blackcoog]

4L will never fit and the 3L is not worth it because of the variable valve timing in the heads which you will never get to work without some kind of custom computer. Its much easier and much much much cheaper to go with a 3L from a taurus.

Did I mention you get the same if not more hp from the 3L in the S type as you do from the 3L taurus engine and SVT parts anyway.

[Rcoug]

What SVT part you will need to achieve 235HP from a taurus or escape engine?? and it's very hard to find used SVT part in Quebec.
The 3.0L hybrid is considered to have problem with overheating, it's why I think to go with the jaguar engine and the VVT heads have a big potential.


Sorry for my english, i'm french

[pythagoras]

well jag s types have 3 types of engines
i dont see why you couldnt but either in a coug with enuff work
you have a 3liter 4liter and a4.2liter
the s type jag 3liter is pushing 280hp vs 320ish from the 4liter and the 4.2 is around 380hp
bone stock . if you can find a complete engine in good condition that would be sweet
definatly give the cat some more balls.

[Rcoug]

235HP for the V6 3.0L in the S-type jaguar


Available Engines

3.0L 235 hp V6
4.2L 294 hp V8
4.2L 390 hp V8

Blackcoog is right. A 3L taurus/escape engine will be easier and cheaper and have more power. Even if you did just a straight swap and put exhaust, headers, and intake you would probably be 230ish~ add pnp to that and you would definetly have 230 crank hp. Throw SVT cams in there and up go the numbers even more!!!

It will be far easier to just do the normal 3L swap. Plus there are many people that have done it before that Im sure will give you advice.

I don't think you will win 35hp only with CAI, headers and exhaust on the taurus engine. Maybe with the SVT cam, upper and lower manifold. But after this you have reach a limit of low budget mods. Take the S-type engine and put CAI, headers and exhaust and you will achieve 250hp easy. The engine is not very expensive, 2000$ for 40k, only 1000$ more that the taurus engine. The problem was : What modifications will be need to put this in my cougar. I know I should reprogramming my computer, but for the taurus engine too for have more gain

[iistevo84ii]

Ok then. Enjoy you Jag 3L swap.:thumbsup:

FYI- Exhaust intake and headers will net you abou 30 hp at the crank, and remember the Jag 235hp rating is also at the crank.

I figure:

~10hp Good exhaust
~5hp good intake
~15-20hp MSDS headers

Im building a Escape 3L with P&P 3L heads split port to match my DH SVT UIM and lower, SVT cams, MSDS headers, Trubendz Exhaust, Injen short ram with GMK extension.

I guarentee you my project will cost less and out peforme a Jag 3L swap.

I dont mean to be an ass to you either, I just dont understand why you want the Jag engine. Tell me, what has you soooo hooked???

[unknown2kcat]

Ok lets throw a different engine in there.
What about the lincoln LS 3L engine it is rated the same hp as the jag but i would guess the price is a little cheaper, I don't know i didn't look.

these motors make that 235 power stock because of VARIABLE VALVE TIMING

blackcoog is right because you'd never make it work without a fully customized PCM, and that is not worth the extra money.......

my advice is to stick with what works

:rolleyes:

unknown2kcat, It's the same price.....


Why do you think the swap with the jaguar engine will be so expensive? It's only 2000$
Taurus engine : 800$
HSDS headers : 660$
exhaust : 400$
Intake : 150$
Total : 2110$
+ installation


I'm not fixed on this engine but I think for 235hp is less expensive mods and the more easy to do but I don't know what mods will be need.

That's completely incorrect.

The JAG engine makes 225-235HP because of 10.5 CR, tuning for 93 octane fuel, more agressive cams (then a stock 3L), better exhaust manifolds and a freer flowing exhaust. The VVT helps shape the power curve but is not a significant power enhancer.

Food for thought about the piss poor JAG output. An oval port 3L Duratec with SVT cams, UIM & PCM makes ~200FWHP (240-245 HP) Tuned ~210 (255+)
JAG sucks!!! 'nuff said.

Most definitely AGREED!!!

[pythagoras]

hey when add a new exhaust and air filter and get 30 ponies out of your svt let me know
well if you cant do it thats ok Jag Did
very little mods and 260bhp (http://www.rsportscars.com/eng/cars/x-type_bonspeed.asp)

Are you missing the whole 3L verses 2.5L part there skippy... ;)

Yes they are saying intake, exhaust, and custom tuning made about 30HP which is definitely impressive.

However 230HP on an SVT is not that impossible to come by either and it's already starting at a HIGHER HP per LITER to begin with so the gains are harder to get.

230 crank = 185-187FWHP Several folks have done that with just bolts ons.
Matter of fact my first dyno was 187+ with the above mods. I made 192 (nearly +40HP) with some S-AFC tuning. Guess that beats Jag then...
I never dynoed with headers, true duals, extreme EH'd UIM, and TwEECer but should have easily been at least 200 wheels. Now of course that is "more mods" then listed for the X-type but just showing the possible results from even a 20% smaller engine.

3L at 230 = 76.67 per
2.5L at 200 = 80 per

Thus making it easier for the 3L to improve on it's volumetric efficiency comparatively and yet the smaller displacement SVT can nearly match it mod for mod. That makes a powerful statement for an engine SVT originally tweaked 8 to 9 years ago.

[pythagoras]

i see your point but im talking right out of the box
and yes i guess you would lose hp once you went away from a awd platform.
which im asuming is less due to the awd

im just saying 30 hp from exhaust and intake is a decent increase that ive not generally seen on other platforms

i just hate all the name bagging from people who dont fully understand performance

As I constantly correct all the folks who state the JAG engine is far superior when for an engine with much more technology and tuning (VVT, higher CR, direct buckets, etc) it is not as impressive as the 7-8 year old SVT tweaked 2.5L was/is comparably.

Jag's 3L is 230 to that 260 you mentioned. That's 185-212FWHP. (AWD loss aside)

A simple pedestrian Taurus oval port 3L with the addition of the SVT manifolds, cams, PCM and stock exhaust (i.e. basic 3L SVT swap) made 202FWHP untuned and 208FWHP with some S-AFC tuning. IIRC 212-215 with exhaust. (don't have my notes handy)

That puts the tuned Jag engine in perspective is all I state.

It is definitely a very nice design. Afterall it's a Duratec. ;) It is just not so vastly superior like a lot of folks claim and seem to think.

[Blackcoog]

The exhaust an intake are minor mods. The real gain comes from the tuning mentioned in the article. Arden Performance claims a 30hp gain from tuning on the 3.0L and the 2.5L engines in the X-type.

[GrandMasterKhan]

I can understand proper tuning unleashing those Xtype motors.

Higher compression, aggressive cams etc should net more than 230hp. But its kinda tame from the factory. Hence tuning netting a great performance increase.

As DemonSVT said the standard oval port 3.0 with "bolt ons" (intake manifold, cams, etc) makes more power than the Jag Engine, despite the fact the standard oval port 3.0 has lower compression comparably and less "technological gimmicks"

[EffingLimey]

If y'all figure this out, can you tell me how to stuff the Supercharged 4.2 liter V8 out of my boss's XKR into my Cougar?

[okay, calm down, DemonSVT -- it was a joke.]

That's easy.

Cut the Cougar body off at the frame rails of the unibody.

Cut it in half and add 2 more doors.

The weld everything on to the big Jag.


Piece of cake... Weekend project tops...
