Has anyone ever installed a supercharged 4.2l into an s type that was originally naturally aspirated?

 

Loads of threads about switching motors, you are better off (money wise) selling your 4.2 NA and purchasing an STR.

 

I'm in the process.. where might I look for such info? THANK YOU VERY MUCH!!

 

Just use Search, but it's much cheaper by far to sell and buy an STR.

You can spend an hour or two reading the detailed stuff and no money, or months/years trying to change the motor and $10,000+ as well.

 

Do you have a huge pile of money?

There are dozens of things different between the SC and NA cars. Then what will you do when you have the power but don't have the big brakes or uprated suspension?

The STR is a complete package and is now pretty cheap. Just no need to mod a regular 4.2L.

i don't have a huge pile of money but i do have complete str that was wrecked. I am transferring the brakes and everything else as needed. I was just trying to get some insight or tips of what i will run into. Any help is greatly appreciated. I understand it is cheaper to sell my regular s type but i wouldn't get anything for it since it has a blown engine and i don't have the money to go out and spend 8-10k on another car

 

Ah, I see said the blind man as he picked up his hammer and saw...

You have an S-Type with a blown engine and a wrecked STR with a good one. Well that's a start.

You should be able to do a swap but it's going to be a pretty large one and complex one.

Good luck, it's going to be an epic project.

So welcome to the machine

 

You'll need to take across a staggering number of things that have been listed in previous threads. You'll need many mechanical (suspension etc) parts as well from the STR or to buy them if they're damaged.

 

can anyone point me in the right direction of a previous post about this conversion? I have been looking for a few days now and have yet to find one post about this. to those actually looking to help me out I thank you for your time and effort.

 

You won't find any posts because it make no sense at all to do it!!

Please read what everyone has posted. I purchased my STR because I found out no matter what I did to my Lincoln LS it would be expensive and still not perform anywhere close to an STR.

I still have the LS and it has been a great car and is now over 100K miles but it will never compare to the STR.

Another negative person, that seems to be the trend on this forum. no help just discouragement. There are very few people from here that are actually helpful. It's no wonder no one goes to the meets.

 

Look at the thousands of messages. They mostly get helpful replies.

You're in the tiny minority (less than one hand full) who want to do something very very hard and very very expensive and insists on getting help of a kind no-one believes makes any sense except you. Think about that some more.

If you think you can do it, grab free download JTIS and compare the electrical guides for the 2 cars. Follow every cable & module. Look at free JEPC and for every different part you'll need it & its wiring and modules. I'll make it easy: you'll need to transfer everything - harnesses as well.

Same sort of thinking applies to the mechanical items but they'll be "easier" (not easy).

Come back in a year or two and let us know how it's gone so far.

 

I suppose it depends on perspective, I'd say people have been trying to be helpful.

 

Despite what you may feel about the willingness of forum members to help, the facts are that there are several important areas to bear in mind when considering taking on a project such as adding a supercharger to a normally-aspirated engine.

Cost aside, there are important engineering differences internally for an engine that is designed to produce increased horsepower and torque by means of a supercharger or turbocharger. Those could be different pistons, rings, connecting rods and perhaps even the crankshaft, all designed to withstand increased stresses. The engine block may also have additional casting lands for rigidity or increased coolant jacket size or added lubrication jets to dissipate heat from the pistons and cylinder walls. In addition, there may also be a difference in the compression ratio to ensure operating temperatures remain within a range that is possible given the type of fuel available for a vehicle driven on the street.

The differences go further beyond the engine to the braking and suspension systems to cope with the increased performance possibilities of the supercharger. Higher volume fuel injectors and a different PCM may be required to increase fuel pressure and flow as well as monitor the gearbox shift points.

Looking at the advice you have been given so far, it is surprising you do not simply find an STR and enjoy driving it.

 

Then the tremendous technical issues outlined above are your #2 worry.

 

This link has Adam, another forum member, with similar aspirations to yourself.

https://www.jaguarforums.com/forum/s...s-type-130572/

There are other links (in post 2 of this link) given by Cambo 351 that will also show similar discussions (mostly negative).

It might be worthwhile contacting Adam to see how he is doing with his project.

But it is a shame that you can't restore the STR that you have for parts rather than the other way round.

Good luck.

 

Maybe people should get a 7-day suspension from the board for being negative?

 

Maybe, did I detect a little negativity in your comment?

 

Heh heh heh, I just went through Adams threads. In a nut shell he decided on a 2005 3.0L S Type. Not knocking him at all but some of the posts that he has made goes to prove that he made the right choice on purchasing the 3.0 and keeping it running rather than taking on the epic task of a engine swap to a V8.


I personally wish you luck with your endeavor, it would be really awesome if you "told" your build story here with either pictures or video. How about sharing what you have already accomplished with the swap to put these negative nellies in their spot!

 

The STR is beyond repair, side and rear damage with a salvaged title..it would cost me more to fix it and it still wouldn't be worth the repairs. To those of you who actually are trying to help I just want to thank you.
