Stage 2 on a 1.0 tsi

Post by Jay11 »

Hi, so as you would’ve guessed from the title I’m crazy enough to be doing a stage 2 for my non-gti polo se 1.0 tsi. From my understanding it’s not been done in the UK before and I love the thought of having something unique. I know most people will tell me to just get the gti but I like the idea of tuning up the standard car and am not really fussed about which one would be better value for money.

With that out the way, I’d appreciate some tips with what to look out for when modifying the car. It’s currently running a stage 1 map (from 95-130hp) and has a custom resonated cat-back exhaust installed, everything else stock. The stage 2 involves getting an intercooler and intake system custom made, along with downpipes and sports cat. Obviously with a stage 2 remap to finish it off. Aiming to go for a conservative 160-170hp on the map for now, but the hardware being fitted would be capable of more than double the power. The build is being carried out by an established company in the UK so the custom made components will be of the best quality.

The engine, transmission & clutch are my concern, this car would be run daily and I’m aware that the standard ones weren’t built to handle the power I’m looking to run them through. Essentially I want to know what else you’d do to the car along with all the planned work I’ve mentioned in order to not blow the thing up. Upgrading the brakes is also on my to-do list so any recommendations for those would be nice too. Please keep the replies constructive, it’s my first car and I’m a newbie to all of this :).

I would like to tuning my polo 1.0 what is your opinion remap or power box? I don’t know where to do a remap and I’ve been watching the race chip boxes.
thanks.

Personally I’m not a fan of chip tuning boxes, from my research they mess with your ecu and there’s been many reports on the boxes causing cars to bring up errors or even go into limp mode. The stage 1 remap on the other hand has really improved the cars performance, I’ve had it for 8 months with no issues. I’d search for a reputable performance/tuning company in your area and see if they could do it for you. Alternatively, there’s many pages on social media you can find where individuals specialise in remaps and will even travel to you, it usually just involves a guy brining his computer to upload the files to your ecu. Goodluck.

Tuning box for diesels - they run on an excess of air, so not much to think about to boost power apart from modest overfuelling at the right times.

For petrol though, I'd go remap, although if you want a tuning box it would probably have to be a Burgersports JB4.

Will the cooling system be up to the extra heat and need upgrading as well?

@Jay11; agree, brakes should be upgraded. I think it would be worthwhile considering upgrading the suspension too if a stage 2 remap is going to give you a performance upgrade that isn’t far short of the GTI. Sorry, I don’t have any recommendations as I’m not into the modifications scene, other than changing the alloys on my car.

You’ve mentioned that this is your first car so I’m assuming you’re quite a young driver (apologies if I’ve assumed incorrectly!). In your position I’d be speaking to your insurance company before going ahead with your performance upgrades to ensure they’re happy to continue covering you and your car. Some insurers aren’t keen on modified vehicles and most insurers view young drivers as a high risk, so the combination of both might mean getting cover at an affordable premium is difficult.

Good luck if you proceed with your proposed power upgrade, and please keep the forum updated.

PS; I like your new wheels that you posted a picture of on your car in the ‘what did you and your Polo do today’ discussion thread. I also have a set of RC Design alloys on my GTI+; a set of 18” RC32 in ferric grey.

Personally I’d be looking to change oil/filters every 6months/6k, also I would only use Shell V Power petrol for the cleaning properties. The last thing you want is the engine to go pop.
Racing line now do an official stage1+ remap and panel filter and turbo elbow for the 1.0tsi.
Also personally I would not go beyond 150bhp so as to keep a certain amount of reliability and drivability. You may need a stage 1 clutch from somewhere like CG motorsports to cope with the power.

The custom intercooler and intake system would also have all the connecting pipes custom fabricated to work together for better/cooler airflow, I was under the assumption that this would be sufficient - are there other factors that I should be looking at?

Thank you! I was also considering the RC32s, they’re a very nice set. Out of curiosity did the wheels change the driving dynamics of your polo at all? I love the design but they were a lot heavier than I thought they’d be (granted I went up two wheel sizes) and have reduced the acceleration of my car far more than I was expecting.

Yes you’d be correct in assuming I’m a young driver, I’m insured with Adrian Flux who know about all the current modifications and I have a rough idea of how the new plans will affect the premium. Let’s just say that I’ve seen some members of the forum reveal their insurance premiums for polo gti’s and the figures are less than one tenth of my current premium 😬.

In terms of suspension are you referring to coilovers? In my original post I forgot to mention that the car also has Eibach lowering springs fitted which have improved the handling dramatically - I feel like they’ll do for now but I guess time will tell.

Yes the car is already run on premium/v power only, going forward that will probably end up being solely V-Power. I have actually tried both the panel filter and turbo inlet from racingline on the car but felt like there was no noticeable difference so they’ve been taken off and there is just a K&N panel filter in its place that gave louder turbo noises, which I preferred.

I know it isn’t very safe to push the little 1.0l past 150bhp but I’m hoping with all the right hardware and due care the car will run happy with a little more & yes the wheels already spin up in first gear with a stage 1, but I’m looking for more pull at rolling speeds. I’ll definitely look into the CG clutch, thanks for the suggestion :).

Can’t say I’ve noticed any difference in the driving dynamics since changing my wheels; if anything it’s probably improved, as I also swapped the factory Bridgestone tyres for Michelin PS4 ‘s. The factory 18” Brescias that I had on my GTI+ were quite heavy anyway. I think the RC32’s weigh about 10kg’s each without tyres.

I’m assuming that the original factory standard suspension set up on your car was quite soft with a fair degree of body roll if pushed reasonably hard through corners. If you’re planning on going stage 2 with around 160-170 bhp, maybe it would be appropriate to consider upgrading the suspension to keep body roll in check. However, as you’ve already made suspension mods, maybe that won’t be necessary.
