VW Golf Mk5 GT Sport DSG - What should I do to it?

[TheAndreYounes]

Hey all, soon I am planning on purchasing this car and I would like it to sound as mean as possible!!
It is only a 1.4 TSI but I'd like to make sure it has VERY loud DSG farts and an exhaust kit to make this happen and I don't know where to start and I am not sure what exhaust kits provide the best farts/burbles and for it to just sound nice in general with crackles and pops if revving or downshifting too.

A tune is a definite also, any idea where to get good tunes in Melb that provide more than 1 stage? That would be awesome, I am a a complete noobie when it comes to all this but long story short, I want to make this car, MINE!

If you have any other recommendations to what I should do with it, please tell me, with a estimated price too! (if possible). Also what does a DSG tune do and is it worth it?

Thank you very much!

Andre.

With the aid of Google, I found this which explains half of your question DSG Performance Tuning | HPA Motorsports, Inc. $750 from Underground Performance.

Not a massively popular engine with the tuners to be fair.

1. Remove the supercharger insulation, so you get MadMax whine. It also lowers the heat soak in the blower.

2. Look at any mods to lower heat, such as an intercooler upgrade, that engine really suffers from heatsoak, ans it will help it stay healthy.

3. Any of the cheap eBay China cat backs for a MK5 GTI will fit with some simple DIY mods, any exhaust shop could make it fit, and those cheap pipes have poor mufflers and are LOUD. Avoid 3" as it's way too big for a 1400cc and will drone something chronic without a resonator in the mid section. 2.5" is fine.

4. A DSG tune is highly recommended, and the Stage 3's usually put more power to the road. The Stage 3 DSG on my Yeti gave me another 40nm at the wheels on a stock ECU tune, but it's a totally different car to drive. I get in stock DSG cars now and think "what's wrong with this car - oh wait...."

5. Be very careful picking tunes, that engine is a bitch to tune well, I'd go with any of the major brands that have done Australian development or have a lot of runs on the board. Easy car to ruin with a crude tune.

6. Get a rear sway bar, transforms the FWD MK5 platform for $300 odd.

7. Again ANYTHING you can do to keep inlet and engine temps down is a good, good thing in the twincharged engines.

This is a can of worms. You'll get good gains but you might bring on an engine failure. If you're committed, have a look at some of the 118 TSI tuning threads here and elsewhere. Also look at the engine problems. Search for lucifer's 1.4 twincharger threads on fixing them up and tuning them on Google.

Everything Greg Roles said is spot on. I'd add that installing a used golf R intercooler is key. So is preparing your engine with all the latest spark plugs, coil packs, N75 and N249 valves.

You will most likely be looking at spending the value of the car again on upgrades and there's a good chance your engine will need new pistons at some point which is another 5 grand on top. If you're cool with that then you'll have some good fun. Otherwise you'll be better off getting a Mk V GTI and a stage 1 tune which will give you more power for less money.

Edit: I don't mean to sound too negative, I love my 1.4 twincharger but you'll soon see that all the guys here that have tuned them ended up spending much more than they expected or wanted. Apart from that, they're awesome, comfy inside, fuel efficient and can be very quick cars for a 1.4 engine.

I thought the nightmare twincharger engine was the leaner fuelled, early run in the MK6 2009 era, I thought the MKV's were relatively ok, so long as the tune is good. I know the first tune I tried on one of those back in 2009 was terrible, it's taken some time for the various tuners to work them out.

The weak points of the engine are numerous and many are common in both the BLG and CAVD engine. The leaner map of the 118 TSI was supposedly the straw that broke the camels back. You can fix them up but if you push it hard and hot you're putting a lot of stress on the pistons and rings, especially in cylinder 4 which from memory is farthest from the high pressure fuel pump.
