As for enginelife??????? 160bhp or 175 bhp or 200 bhp will not make
much of a difference to the engine block, really.

you also must remember we are talking diesels, not petrol turbos, and
as a diesel runs with an excess of air in the first place, then you
have to realise that tunning to 165/175 bhp if done properly does
not involve a major boost of the turbo.

also if you decide to upgrade the intercooler, then again you already
have a possible 160bhp plus car, without doing anything else to it.
so how anyone can claim it has an effect on engine,is behind the
times.

Any real problems involves the turbo, which is not the engine and
badly done remaps with spikes.
and yes the clutch can be an issue due to the huge amounts of
torque, but as has been said already, a good tunner would be able
to dial round this, to a degree...
Well...the guy who told me this is no ordinaryTuner who just came in on the 4 o'clock train and opened up a shop.

He tunes Alfa, VAG, Mercs, BMW and been in the game for 20 odd years. He runs one of the most respected tuning shops in Denmark. People from North Germany drives up to have him remap their Diesels.

You can disagree with him, and I do not know exactly why his limits is where they are, so I can't reallly comment on your thoughts.

But I think I can wouch for the fact that guy knows what he is talking about.

Peter i do not doubt the chaps credentails, i have told you what i
believe to be the weak links when tunning the jtd.
maybe you could ask your friend why he states what he does?

ie. what actually breaks on the engine?

Never really heard good things of Celtic Tuning and unfortnalty the site dosen't really inspire confidence when all the links fail to work!

Would be intrested in the FMC and hybrid turbo that you talk about.

jtd lover: Give me 2-3 weeks and I bet you I have the most powerful 2.4 JTD 10v on here....

now that sounds good... you let us know then ! I believe that around 215-220hp you can get. but with some mods to the injectors or high pressure pump ( 1600bar ) you can get even more.

@ Si Swift... sorry to hear you've not heard good things about us?

@ Jarkko.... It will be 'slightly' higher than 215-220bhp... the key is in the torque limiters. I wotn say what I'm aiming for, I'll post the dyno once done.

Thats ok,

Open to being proved otherwise. As i said it's not my direct experince!

Glad to see the links on your site are working! Are you selling kit's for the FMC or are you still in development stages?

The kit is currently in development which is why the links weren't active...

Will be complete within 1 week and will then sort out a kit option for DIY enthusiasts.

Re: who has got the most powerful 2.4jtd 10v engine?

you can chance the fuel pump... and you can put the new 200hp jtd engine injectors to your car. so the fuel side is good for at least 250hp.

Can you tell me what exactly has been done to your gearbox? And how much torque it can handle now?

How about the clutch? Is there a better one available? Or do we have to get a custom?

The fuel side is not a problem. There are bigger injector and a bigger high pressure pump available.

Re: who has got the most powerful 2.4jtd 10v engine?

Hi,

I own one 156 from 99, the 136hp unit.
I already have the GT23V to mount, but i'm doing new exhaust manifold because the original one cracks at highway use (4800-5000rpm).
I will fit FMIC and will re-work the clutch.
I'm thinking in fitting the 6-speed gearbox.

I will post pics has soon has i'll take them.

Cheers

That's a large enough IC friend had a huge one on his Gt Starlet was meant for a 600bhp+ RX-7 lol only got it fitted because he got it for free caused some serious lag even on a standard CT9 turbo.

Could you use any sort of IC from any car or does it have to be specific for petrol or diesel??

Re: who has got the most powerful 2.4jtd 10v engine?

is the gt23 from mercedes 320cdi ? I´ve been told that if using vnt-turbo, use the biggest you can find. othervise the clutch and the gearbox are near to the limits. ( huge low torque ) gt23 is good turbo in this case, and it can be modified even bigger.
