After much difficulty trying to research turbo upgrade options for other members, I decided it's probably worth making some sort of list of turbos that can be bolted straight onto the 1.2 TSI. See the second post for a quick simple installation guide and other suggestions/advice. Which Turbo do I want? For some reason, despite them all being pretty much the same power, and all being used in what's effectively the same chassis, there's about 25 different engine codes and just as many different turbo models. It's quite a mess, so i've tried to organise them here. It's also just been made aparent that there's some variants (seems like any ACT ones) which use a different style of wastegate actuator, they're also made by a different company and have different turbine designs, they should all provide the same final power, but might have slightly differing boost characteristics. 1.2 TSI Turbos - Standard - The original turbo on your car should be one of these, unless your turbo died, there's no point buying these. 04E 145 721 L 04E 145 713 B 04E 145 713 Q 04E 145 704 T 04E 145 704 L 04E 145 704 N 04E 145 703 Q 1.4 TSI Small Turbos - Avoid - Same size as the 1.2 TSI but with different shaped exhaust housing, you won't see any gains with these. 04E 145 721 E 04E 145 721 R 04E 145 713 N 04E 145 704 F 04E 145 704 R 1.4 TSI Large Turbos - Avoid - Has an additional sensor on the exhaust housing, stay away unless someone confirms it's removable and fits. 04E 145 721 C 04E 145 721 G 1.4 TSI Large Turbos - Avoid - These have a different type of Wastegate actuator, stay away unless someone confirms it works. 04E 145 722 G 04E 145 721 P 04E 145 715 B 04E 145 715 D 04E 145 715 E 04E 145 715 F 1.4 TSI Large Turbos - Best Choice - Matching Wastegate and confirmed working by myself and others. 04E 145 721 B 04E 145 721 F 04E 145 704 C 04E 145 704 P Purchasing Options New turbos can be bolted straight on the day it arrives in the post, though they're incredibly expensive and will set you back potentially by more than £600. Remanufactured/Refurbished turbos are a cheaper alternative for an equally safe purchase, and are also good to bolt on the day it arrives, these go for usually around the £350 mark, sometimes some pop up a bit lower though. Used turbos are by far the cheapest option, but it's advisable to have it rebuilt. A used turbo will set you back around £100-150, having it rebuilt will cost you around the £100-150 mark, total cost roughly £250. When purchasing a Used Turbo If possible, collect it in person before commiting to the purchase so you can inspect it to ensure it is the correct part and that there is no damage. A damaged turbo can still be repaired, but a repair will set you back closer to £250-300. If there's any damage to either intake compressor or exhaust turbine, or if it does not rotate freely (be very gentle when attempting to spin it, it's very fragile), it's not worth your time or money. Use brake or carb-cleaner to clean out any oily residue (try not to get it in the oil channels, as you do want oil in those, but cleaning the coolant passageways is fine). But again, do not poke anything in the blades, they are easily damaged! I'd recommend to check a few turbo refurb companies for rebuild prices, then checking how much you can get hold of a turbo for, both used and refurbed, and proceed from there before actually purchasing anything. Disclaimer should you choose to install a used turbo without having it rebuilt or at least inspected by a professional: I advise against doing so, and I shall NOT take any responsibility for any damages incurred by YOUR actions. Turbos spin sometimes upwards of 250,000 RPM, the slightest of imbalance from any kind of damage, can result in catastrophic failure! This could potentially send metal shards through your engine, completely ruining your engine too! Just get it rebuilt already!!!
