More power, turbo style

It maybe strange but thats what they use

What an excellant site!!

Any idea what they're lining the up-and-coming magnesium blocked engines with?

I couldn't believe it when I bought an E36 M3Evo engine and found it had an iron block! I know they did it to keep the block size as small as possible, but you try moving one!

Certainly the Jag AJ blocks should have been up to the task as they were originally designed to be part of a family of engines which included a diesel!

Anyway, the diesel design was canned, but the block wasn't re-designed so for a petrol engine, it's unbelievably rigid!

Re: Nikasil, why is it that Porsche managed to use this in their engines without any problems whilst BMW and others fell flat on their faces!? I hear that supermarket fuels with unusually high sulphur contents are responsible for causing nikasil problems so if you've got one, then avoid these cheaper fuels. Cheap in the short term, EXPEEEEENSIVE in the long!

Skoda used to make a turbo version. It went well, but the engine would last 25000 miles tops, about 1/3rd what a standard one would manage. Unless you are dealing with a very understressed bottom end, you can expect the same from a home-brewed conversion at best.

No-one bothers to make a turbocharged motorcycle any more; the reason is that by the time you've messed about putting a turbo on a small engine, you might as well have had a bigger one from the start.

The same goes for car engines to a great extent (although turbos are fun to drive).

Most people I know who have had one have eventually wanted to 'experiment' with the boost pressure and have blown their engines up.... 

So I'd be tempted by a small V8 lump or something like that, if tuning the standard lump (220 to 230bhp not too difficult) or replacement with a big 6 (3.5 litres anyone?) isn't enough for you.

Still, I'm sure you'll have fun whatever you do....

cheers

 

Chasseur, surely reliabillity issues depend on how much extra power you are hoping to get. Since GT6-M3 is only talking about an extra 70bhp then I doubt he will have many problems with engine components disintegrating on him. If he was talking about an extra 170 then maybe. Also the problems with the developement of the jag were probably due to the the quality of the standard engines in the first place. It's only in the last few years, since Ford took over, that Jag have started to make cars properly.

a while  back i had a Jaguar Twi Turbo "Chasseur" 4.0, these are stripped out Jag's fitted with a Blueprinted engine in fact the engine design/tuning was undertaken by Turbo Technics in Northampton,you may have heard of them,the suspension was developed with Leda & Baileys, recalibrated steering racks etc. To top it of the brakes were uprated ,all the water hoses & brake hoses were stainless braided & the exhausts & Manifolds inlet/outlet were developed & designed by Piper's of Devon along with the Camshafts etc You may have heard of them also. Anyway they topped it of with the interior an exact replica of the Bentley Turbo "R" there is so much leather the only way to have more surrouding you were if you crawled up a cows Ass!

Now these cars moved & handled like a dream bearing in mind they are 2 ton+ but even with all these top firms designing  inlets Exhausts , Turbo Technic's made there own Patented ecu's one for each turbo pus the cars o.e. one  even using 6 extra uprated injectors from a A.M.DB7 V8 to work alongside the cars O.E. when on full boost (which was only a lowly 6psi) they still had quite a few problems that they(Experts) had't banked on SUCH as gudgeon pins disintergrating, pistons that were NOT drop forged but from the U.S. 4.0 Jags because they were lower compression cracking around the skirts due to "Knock" at boost. Now all this developement    lasted 6 years & the car was tested at the MIRA test track during **** development cost a bloody fortune ,so much so that C.D Developements went bust 3 time's & is now called Paramount Performance .

So GT i do hope that your that good with your fabricating &remapping etc & perhaps you could drop Pipers & T/Technics a line to help them out Ha Ha Ha Sorry Mate but honestly there is no Safe(engine wise) cheap way to properly Re-Turbo a NoN Turbo engine unless you spend big after this Rant ask me about the Money spent on a Twin Turbo Maserati .now that will make your hair curl & make s the Jag feel like a shopping Trolley but not much fun in traffic jams & you've got to inject A/Steroids in your clutch leg to.(BIG FUN)

Of course there are.

If you buy a kit, you're paying some other companies overhead & profit, then you're paying for the components themselves.

If you can fabricate all the required bits yourself, which mostly comes down to plumbing, you cut out a huge chunk of the cost.

Also, as I've said in most of the above posts, I would be buying a fully mappable ECU which takes care of fuelling and ignition which means ditching the dizzy and old ecu altogether. None of this resistor pish or "chip" bollocks.

Why in gods name do people think this is some kind of black art!?

Also, why do people assume that if you're turbocharging a car that you must want a million horsepower?

I would consider Eaton's offerings as you can pick up M45s on e-bay for around £200 which have about 10miles on them.

However, I already have a shiny pair of turbos kicking around :)

Yeah, my only problem with NOS is that whilst it's cheap to install in the first place, the refills can be expensive.

Also, it would suck to be in a situation where you needed the power but couldn't have it because the laughing gas had run out.

Again, the engine needs to be in good nick to reliably use NOS.
