Hey Guys How is it going?
With so many of our BHPians Turbo'ing their rides and Vikram the latest to join the Turbo tribe i have a few queries.

Keeping in mind a few constants:-

1. Only reffering to the DDiS Multijet(Diesel Varient Swift-With Factory Fitted Turbo).
2. I understand the Swift DDiS comes with a FGT.
3. Following is only after installing a CAI kit and a FFE.
4. Not willing to modify internals like lighter cams, forged internals, except for a clutch as i feel the Swift has a weak clutch.

Now for the queries:-

1. Is it possible to push up boost to 8psi(considering thats the max one should go with stock internals ), i guess stock is 6psi, by modding the ECU or with a piggyback? And does 1 or 2psi increase makes a difference in performance?
2. Does a Pete's Tuning Box only modify the AFR, timing etc or does it also increase turbo boost?
3. Will a larger intercooler help in performance and efficiency of the engine.(By Efficiency i am not reffering to fuel efficiency).
4. And lastly with a CAI and FFE in place can the Pete's Box be set to the second stage?(If any body has approx. output figures of BHP and Torque.)

So all the gurus and BHPians out there please put in ur views and knowledge and i guess your answers will help those who are tight on budget and looking for soft mods to their diesel Swifts.

Thanks a ton guys!

I am not a guru in this case but AFAIK FFE in a diesel is not easy job.Have never seen one till date and not much of them in India.Rest of the said mods seems ok.

Pete box only modifies AFR, not boost. A larger intercooler always helps, as there is a larger ares [volume also] to cool the intake air. and having a FFE [ the car will be noisy]and CAI helps with the +2 stage on pete's box [ fuel consumption increases though].

We have a Diesel Uno in bombay running around on an automech FFE. It belongs to a fellow BHPian..

the FFE will be more noisy than the ones in petrol cars..and a turbo car's headers should not be messed with since it may affect the air flow to the turbo..

FFE has not been done by anyone yet, on the forum, and the general opinion is that its not worth the trouble.
2. Does a Pete's Tuning Box only modify the AFR, timing etc or does it also increase turbo boost?
AFAIK,The tuning box is supposed to change only the injection timings. no concrete reference there. I'm going by what more knowledgeable members have said
It definitely does not change the turbo settings.
3. Will a larger intercooler help in performance and efficiency of the engine.(By Efficiency i am not reffering to fuel efficiency).
I've been thinking about this too
4. And lastly with a CAI and FFE in place can the Pete's Box be set to the second stage?(If any body has approx. output figures of BHP and Torque.)
You dont need the FFE to go to 2nd or 3rd stage, the box has been optimised for performance in 2 and 3 with just the CAI as add on.

before anyone jumps on me, I'm no guru, just trying to wring the max out of my swift.
PM peter for details.
also-mclaren1885 has an interesting project going on a DDIS. but he's awful tight-lipped about it

DTE tuning box
Pipercross Air filter

Guys Thanks for the response, as far as the FFE is concerned, i was aware of the fact that Diesel Turbo headers should not be touched unless in the hands of a expert so maybe a cat-back would do?
And if i understand correct stage 2 and 3 on the Pete's is one own will to set and does not depend on state of mods?
Gurus your inputs are required and awaited.

Bro is the DTE available throughout India and DTE is the one from U.K right? With 9 or more different settings? How much does it cost?

Pipercross CAI kits were earlier disscussed elsewhere in the forum to be suitable for drags and not a mix of city traffic and highway driving as performance is delivered in the powerband only and in the city, keeping the engine in the powerband for long is rarely possible due to increasing traffic, lack of space and road conditions.

I disagree. Pipercross is quite good. Though in reality changing the arifilter doesnt really make that much of a difference.

Try it and see. It makes a crapload of difference on a turbodiesel.

Lol, is that so? How come we never hear about this stuff?

@vip3r- what is mclaren1885's signature referring to?

Drifter on the forum had one on his Hyundai Accent CRDi. I don't know if it makes any difference in performance.
