I want to slap a supercharger on my 3.2! But only because it has low-ish mileage, and XJR with similar miles would cost me 5x more... :P

 

My XJR has 243,000 kilometres on the clock does not blow smoke or use oil starts first kick even after 3 months not being used

I intend to see at least 400,000 + in my ownership

Ill tell you then what's gone wrong with it LOL

Most of the problems I have had have been rough mechanics and crap coils

I have spent a bit on modifications and upgrades Though LOL

Makes it all worthwhile get a XJR as well

 

Firecrow,
It would cost far more in parts to supercharge a 3.2L AJ16 engine than it would to buy an XJR6. The two engines don't even have the same cylinder block !

 

I'd like to update this thread. I'm turboing a 3.6 myself. The 4.0 compression isn't too high. The BMW s54 has made 700whp on stock internals which is 12:5:1 comp.

 

Any engine can be boosted, but not all will respond the same. The combustion chamber, head design as well as intake manifold will dictate the power potential. I've turboed engines of all shapes and sizes, what it comes down to is your tuning. Your tune is the most important factor. Sure you can get away without standalone for a while like I'm going to do, bit it's not forever nor can you extract the same power levels. Tuning is key. A bad tune will destruct a motor in under a minute, ask me how I know lol. However a properly tuned and set up engine will last. YOU HAVE TO HAVE THE SUPPORTING MODS FOR YOUR SETUP I CAN'T STRESS IT ENOUGH! By this I mean fuel pump, injectors and injector adjustment. Also you best be sure everything else is in line before you even think about this. Your cooling system, crankcase vents and ignition better be fresh. And if your motor already has any performance related issues you'd better address them first. Maintenance always comes before boost.

 

This it interesting.but no doubt it will be expensive. Custo exhaust manifold and dowb pipe. Making the harness for a standalone ecu, fuel injectors, regulator, pump,turbo, intercooler with pipes, wastegate, blowoff and with no reference on tuning or power capabilities of the engine man its not an easy or cheap project. Not to mention if the transmision and other drivetrain parts can handle the extrapower. I would be happy with 400hp to the wheels. But then i would start off with an xjr or xkr

 

After careful consideration and a bit of research, I myself, have decided to go supercharged versus a custom build turbo setup or 6.0 12. I have thought about just buying an xjr, but considering that all I could afford as a vdp with almost 300k miles on it, the option of buying a decent xjr versus just the engine/transmission and doing the work bit by bit...well you know the rest. Wine taste, beer budget... It would be nice if anyone had blueprints for said engine, so if I needed to rebuild the engine once I got it, I could locate parts that might work. For example: piston/rod for a Ford, Chevy, Toyota, etc... that might be made to work with a little machining. Finding Jaguar Parts(overbored pistons, etc...) has proven to be a challenge.

 

you know i spoke to a guy that did his xj6 turbo. he made it a rear mount turbo so no custom job for manifold just simpler connections on the exhaust pipe any muffler guy can do. then the intake pipe must also be routed under the car. the flow meter wiring must be extended to the rear aswell. he had a wideband sensor , one of those big 10:1 fpr. stock injectors, stock engine, stock everything. the hard part is finding the perfect place to mount the turbo and wastegate under the car where it wont slam into the floor or suck in water on a rainy day.

 

quick pix of my remote turbo system, keep in mind,you are just looking for some positive pressure in the inlet manifold,simple right?

you are not going to build a turbo F1 engine!(are you)?

anyway, remote turbo does work!

 

o.O don't drive that in the rain o.O WTF did I just see?

 

I completely forgot about remote mounted turbo setups. This might actually work out cheaper, and easier considering you wont have to fabricate an exhaust manifold. Really the main thing standing in the way of turboing a 3.2 or 4.0 is the lack of knowledge/ people who have attempted this or similar things. even when talking about appropriate turbo choice it would be very nice to have a reference of some kind as to what works, in saying that are there any other engines that are similar to the AJ16 where one could research about turbos etc. off the top of my head I think the Ford 4.0 inline 6 turbo out of the Australian Falcon XR6 turbo could be somewhat relevant but im not sure.

 

If i were to do a remote and probobly the best choice for simplicity. I would raise up the spare tire well. Put the turbo there, have room to split off the exhaust and run the air intake into the trunk on the side. And since i just bought a really nice 95 vdp with 29k miles to replace my totalled 96. I just may do this down the road with a sts kit

 

I have thought about the rear mounted turbo on several occasions. Even seeing if it could fit in place of the cat and still have the intake in the engine compartment somewhere. Either way, I still don't think it would be wise to boost my engine with almost 300k miles on it. It would certainly expedite its demise.

 

Well, maybe not. The idea of having a v12 under the hood is too intriguing to make a final decision...alas

 

Good idea, a V12 with twin remote turbos, that would make thing a bit more serious!!

 

Plus, if it is actually true that a gm transmission can bolt up to the 6.0L, then that means I can find a way to bolt up a manual transmission and not be limited in my choices. Hmmm... a 6 speed v12 TT VDP...

 

if you have a 6.0L Jag , it comes with the GM 4L80E trans, much better ,more consistent, all around better than manual trans.

they can be shifted just like a manual, you can go up a gear or down a gear, AND NEVER MISS A SHIFT!

if you have ever done any street racing, every time you shift a manual you lose around a car length,(auto dont fall back when shifted), now you gotta have a lot more power to make up the lost car lengths!

 

Eh, I've never had much of a problem losing ground while shifting. Maybe a bumper length or so. The trade off of that bumper length is worth the gain in power that the auto trans soaks up. Strictly drag racing, I've gained 2/3 of a second in the 1/4 mile simply by switching to a manual. Both the auto trans and manual being in stock form, but that is a conversation for a different thread.

 

you do know that with twin turbos and manual trans, each time you shift you should let off the gas, turbos lose some boost, and it has some lag before coming back up!

with automatic, you keep your foot in it, and dont lose any boost, it is a different kind of driving style, course you could go big bucks and get a manual trans. that shifts at full throttle.

and last but not least , other day drove a 2013 camaro ZL1 supercharged, with 6 speed AUTOMATIC, yes i was in for a treat, it was fantastic, automatics have come a long way,
aint know way you gonna shift a manual down a couple-three gears in one split second, like on a hi-way roll!!
you be playin round with the shift lever trying to find the right gear!

even the drag race crash boxes dont go down shift easy, sometimes not at all.

your right this topic for another thread!

 

Ah, bench racing is so much fun!
