regarding airfilters on a diesel, I was told that theoretically it doesn't improve anything, but some folks have reported a marginal improvement

Some food for thought :

Headers may not work as efficiently as in a petrol because many diesels dont have valve overlap. Don't quote me on this though, headers are still a long way off for me as far as diesels are concerned.

2) For a turbo car:

Part 1:Maximize velocity upto turbo
Part 2: Dump.

Good News: The factory guys already did part 1 for you

Better News: They didnt do part 2 so its very easy to make your car stand out in terms of performance. Run a diffuser (or a plain large pipe that matches turbo exit if space is an issue) into the largest possible plenum you can fit under the car. Then, use the stock exhaust after that. See how the evil diesel starts flying after that!

The exhaust pipe in DDIS is quite good, look under and you will understand. Its kinda straight pipe and a huge one. Only restriction per say is the last box.

is he talking about the boost controller?
I thought it had something to do with bad breath or flatulence.

Yeah, I put the car up on a hoist and checked it out with some people who are well-versed technically. We were amazed at the quality, and it says Suzuki on the centre muffler and other parts. All SS, and not MGP.

depends on how much moolah you have in hand, then let the mods and tuners begin

Honestly get a Pete's box, i assure you will be kept entertained for atleast next 12 months

Electronic add-ons for turbo diesels might undergo a new phase very soon in India. Wait and watch.

Because you are busy in your own world. Take time to reply to your SMS'. Maybe then people will tell you things .

Coming to topic at hand I am sure the following can be done:

1. Upgrade to bigger turbo.
2. Upgrade ECU or get a programmable piggyback.
3. Turn up the boost a little.
4. Get a clutch that can hold it.

All quite possible. All it takes is someone with a willingness to do it and some moolah. Whose volunteering?

Have not yet started research on the Ddis yet, but for eg the turbo on the sonata embara can be used on the elantra to get better results. I know someone who wants to check out the possibility of doing the same on a swift. Will keep you guys informed. As for the clutch I am getting some info from a US based clutch manufacturer to make a custom clutch in case none are available off the shelf. All one needs to do is send a OE clutch for reference.

How easy or difficult is it to substitute a turbo on an already turboed car?
I'm guessing it should be easier than working on a completely NA car.

just a dream here, how about finding the VGT that comes on the 1.3 diesel in the punto for use in the swift DDiS?

is that practical?

Replacing a bigger turbo on an already turboed car should be easier than turboing a NA car from scratch.

But one needs to keep in mind that you have to take care of the fuelling as well. Get a diesel programmable piggyback. I have a birdy whose looking into the possibility of using a VGT on a non-VGT turbo car. Besides once you upgrade the turbo, be prepared to have more lag as well.

ofcourse there will be more lag, thats ok! the boost will make up for it.
I actually like the lag, because i know whats coming after it.
About using a bigger turbo that is also a VGT, wouldnt that offset some of the lag?

A programmable piggyback would be the best one stop solution, but cost? Also, technical know how to actually program it would be beyond amateurs like me. but the good part is, your electronics will always be able to keep up with the mechanical upgrades you install.

its a lovely idea.
all we have to do now is wait and see what happens on the programmable Diesel ECU front.

how long will it take to be launched?

I don't want to spoil the little birdie's plans. So lets wait for the right time shall we? All I can say is, some of us will be in for a big surprise.

Please do not fiddle with a stock turbo. If it would have been a petrol, I would have recommend you to go for it.

Just use a Pete's Box, and change the filter to k&n or like.

Could you elaborate? How would it be safer on a NA car and not on an already TCed car? Id rather prefer treading into known waters than unknown.
