Yes there may be some sort of royalty involved with the engines, but If IDI engines could not take diesel adulterations [which was/is common on most of the hichways not in cities thou]as good as the DI can [ know it from experience] Had the 750DP for almost 10 years and also had DI for same time, now Have two DI pickup, they are more reliable then the XD3P.[have not had over haul for more than 160K KM on both the DIs, where as the IDI engine had to be overhauled at around 110K KM].

If the XD3P is available in 4x4 as per the Mahindra Bolero website then its probably BSIII compliant.

DI engines are definately rugged and has more life in them. Thats the primary reason why DI engined powered vehicle sells more than XDP engine cousins. Bolero is indias No1 selling vehicle today....not for looks, but for DI engine and phenomenal mileage that u get out of it. It wasnt No1 selling vehicle when sold with IDI unit.

Di engine can be started even with battery dead, Di engine easily crosses 2 lakh mark before overhaul, Di is better on mileage and now reasonably refined. For mahindra it is cheaper option to produce with lot of common parts thus favouring economies of scale. IDI XDP was discontinued for not being able to meet BSIII norms and also primary aim was to keep few engines in range rather than too many options as mahindra offered earlier (XDp 2.1, 2.5, MDI 3200, ISZ 1.8 petrol, Scorpio 2.6 SZ engine, P4 engine long time back and also 2.1 litre CNG option). Fewer engines makes logistics easy and also makes commercial sence.

The present DI turbo is also capable of meeting BS IV norms with few modifications. The BS IV 70 BHP and 22 KGm torque and will sport a chain drive engine. This engine is due in 2010

Bolero 4X4 can not be registered in the metro, they are sold else where in the country, My friend had inquired as he wanted one in mumbai, and so he had to get a vehicle in his home town and register it there.
The BSIII norms are enforced only in metros and some major cities like pune. else where in the country BSII is the norm,it's always been this way one stage lower than the metros, companies would have lost money if it was enforced at a time. Old inventory had to be disposed off so this concession is given to companies.

@GTO , did you get a BSIII engine?

this is very interesting 22Kgm should be very good.

vinod_nookala, by chain-drive, you are of course referring to the drive for the cam-shaft, right?

Thats interesting, Vinod, the world over is moving from chain to cogged and poly vee grooved belts in sealed enclosures to reduce engine noise..and decrease maintenance intervals, and we have mahindra going the opposite way..are you certain?

[vinod_nookala]

Blue thunder
Yes iam reffering to drive for cam shaft....

True but thats not the case with budget Muv & Suvs. The present engine is gear drive engine hence so much of noise. Chain drive will make it lot more silent. Initially even Scorpios engine was a gear drive one in 2003 models, made lot of noise. Next follwed chain drive engines (Non CRDe) with decent NVH levels. Today all the scorpio range engines are chain drive for timing. As far as i know no SUV in india offers grovved belt for timing. Correct me on this, earlier Sierra had belt drive for timing and tata moved to chain drive for more reliability.

You may be right..will have to check..The vehicles I've seen with Timing belts are: Fiat Range[Uno, Palio], Maruti range of vehicles, Hyundai range of vehicles, Ford, GM etc..

Today, Timing belts are proved the world over to be better than timing chain and gear drives even with respect to reliability. Hence all these new vehicles come with Timing belts which also make the diesels more silent.

The importance of moving to timing belts is that the belts are to be in a sealed enclosure to prevent unusual wear and tear. Apparently, the service jokers dont fix the cover properly leading to timing belt snaps and a major work later on..

The real problem is in the service team and not the design!

Well..straying a little
Tata Sierra was an experiment by Tatas. They learnt a lot. I still think that body shape has tremendous potential. Our Nitrous could help us get a new 2.2 VTT Dicor for 50K. Add another 20-30K for the shell with drivetrain and we have a hot vehicle.

Add a 4x4 with Borg-Warner shift on the fly t/c and ...well i can imagine one coming to offroad like that: LOL

Why is Mahindra with regards to the bolero still stuck with these old engines in new avataars... still delivering around 70+/- bhp. And they are still stuck with the leaf spring suspensions on the 4x4. Their approach to the evolution of the Bolero seems to be the cut & paste approach where they keep making small changes every year or so and then call it "all new bolero". Is the customer a fool or the manufacturer a bigger one. The customer buys what he gets within his options. BUt manufacturers dont seem to provide enough options.

2.2VVT dicor for 50K. Well if that is true, then iwouldnt mind buying a second cheap old safari with a good chassis and plonk a new 2.2VVT in it.

If its isnt broken why fix it? Similarly if its selling why bother. Bad attitude but works. They only changed the engine because of the emission rule orelse they would have been happily selling the Peugeot.

any updates on this, GTO ? Hope you are taking pictures of the engine replacement job, and do post them in your long-term ownership report of the Classic.

Eagerly waiting for this

Of course, there is an update! I will post the pictures and a detailed report upon delivery, but here is a quick brief:

Completed:

1. Engine installation
2. Gearbox overhaul
3. Front & rear suspension overhaul
4. Brakes replaced / overhauled
5. Diff & axles overhauled

Pending:

1. Electrical system overhaul
2. Air-con installation
3. Exhaust piping
4. Soft-top.

Thats it! The workshop is Mahindra-owned so part & labour quality is factory grade.

Isn't the above specs same as Scorpio M2DI ? If yes, what would it take to buy a Bolero and modify it to the specs of M2DI ? Is this possible ?

[dinar]

waiting for the update , GTO hope to see the jeep soon. you have the same 4 speeder in or are you getting somthing different.
