You can do anything and everything if you have these - Money, Time, Energy, and most important if this is a project car. If not, nothing more. Period.

Tata was never good with petrol engines irrespective of the model and year. Even the Tiago JTP was not 100% Tata developed. It was developed in collaboration with Jeyam Automotive, Coimbatore. So there is a serious limitation in terms of RELIABILITY to extract more from the stock.

At the same time, Altroz diesel is a different beast altogether, especially when it comes to mod potential. Of course, with limitations again.

Btw, I would say those 180/200 hp 1.0/1.2 TSI polos may not be daily drivers. One of my friend Bhpian has a 300hp 1.6S fiesta and its not a daily driver. plus it needs special maintenance, highest 99RON fuel and so on..

Altroz petrol (not the racer) is one of the most boring cars to drive. And Altroz diesel is one of the best drivers car. I would not even do a stage 2 with Altroz petrol, let alone more mods.

I am no expert but reliability and after market mods don't go hand in hand. It's better the car remains stock and be driven as it is IMO.

Like @pedrolourenco said, you can have fun even if it's sub 150 bhp. Maybe try better springs and brakes to get better entry and exit speed. Cornering is as much, if not, more fun than outright acceleration

Yes, this sounds like the right path to follow - I will be researching about and hopefully will get through with the mods by May-June 25. I had reached out to some tuning houses and they do support other stuff like slotted rotors, braided brake lines. and even some head work on the block. Will keep the thread posted.

Thanks a lot

Yes, I am aware of the Jayem ties and how the 3 pot turbo mpi engine made it to the tata house, But the rationale behind the potential gain for power was that the nexon does better figures stock - and those are proven to be pretty reliable from a engine perspective.

The thread is regarding the iTurbo, not the NA Altroz - you are right, the NA block is anemic and should never have been an option for a car in this segment. The iTurbo is the same engine as the Racer (with a different ECU). Otherwise mechanically same to till the flywheel.

This block is easily much more fun than even the diesel, with the power being very linear and enjoyably after a stage 1 map. The lag in the diesel is just abysmal -- not to mention the 2 second delay in the throttle response really sickens me to the gut every time i drive one.

You are right, I probably am getting a little carried away with the numbers. The chassis dyamics, steering and suspension being so good, I really feel that she has a lot more to give.

For the part of always having to run a higher fuel grade, I am fine with that - My iTurbo is already on a 95 RON ONLY map and it really is not a hassle at all!


Will keep the thread posted with further updated

Hi there!! It was a nice read going through your posts. We have a diesel altroz tuned to stage 1 and were wondering for a brake and tyre upgrade. Tyres are stock 185/60 R16s right now and was thinking about upgrading to Vredestein Ultrac Vorti - i 205/55 R16s since they feel very good on my polo tsi now but you've mentioned wheel rubbing in the rear arch which is sad. Have to hunt for quality 195/55 offerings then for when the car needs new tyres...
About the brakes - brakes are fine but an upgrade would definitely be appreciated. Are there any performance pads and/or rotors available??

Thank you for your kind words. In practice, the wheelwell rub is not bad at all, and I'm actually running the same factory wheelwell that came with the car (I'm running Michelin Primacy 4 195/55/r16 now).


The damage (more like wear honestly) is pretty minimal and is absolutely not a problem. It only happens at a specific angle just before full lock to either side.



As for performance brake pads or rotors. I'm myself out on a lookout for better pads/rotors for this callipers. From what I have gathered, the Petrol/iTurbo's smaller rotors has better Oem-replacement support like Bosch's ceramic composite pads. Those were pretty good but were too harsh on the rotors (I honestly don't mind replacing rotors every 20-30k kms if the braking performance is better). But unfortunately such options don't seem to be available for the diesel size. I've tried to reach out to brakeup.in but even they didn't seem to have options from reputable vendors like bosch, brembo, ebc.

There are currently active threads and communication channels open with both brembo and ebc to develop pads and rotors for Indian cars (tata Mahindra etc).

As for options currently available to us, Raceconcepts BLR have options for steel braided brake lines for better pedal feel and also modding the rotors to be slotted.

Apart from that. I'm not aware about any other options. Please do let me know, I'll keep this thread updated with further leads that I get or mods that I might do

Invest in a better subwoofer I'd say. It should tie the whole setup nicely. Underseat sub, especially Harman doesn't sound promising enough.

Hi,

I also drive an i-Turbo, with wolf stage 1+ map. I have also installed cobra lowering springs with MRF Perfinza tyres and using an HPI air filter. Currently I'm happy with the setup. Just wanted to know how good is the diesel Altroz's brakes in i-Turbo?? And how did you procure it? Boodmo?

Also, I think K&N is manufacturing stock replacement filters. Has anyone installed it? Code6 has a stage 2 map for i-Turbo. Any thoughts on getting it done?

Thanks.

The diesel Altroz's brakes are a direct fit (the Altroz CNG and auto also uses the same setup). You need to buy new calipers, brake discs and pads. It's a massive upgrade, I'd say. Feel is way better than the stock, which is subpar, especially if you have a remap. Boodmo is a little tricky, they sometimes have it, and sometimes don't. I sourced from a parts dealer in Bangalore.

I've added the K&N replacement filter too. Works perfectly fine. I've got a stage 1 Code6 remap. Pretty satisfied with it.
