Hi, looking to get at some hop ups on my a45 I recently brought. Anyone had any experience with them and what the reliability is like once you start getting to some bigger hop ups for example bigger turbos.. seen something about the gearbox and drive train being a issue once you get higher bhp.. what’s the engine internals like? Thanks guys

M113 is the old 24valve V8 - are you after advice for that or for the A45 you mentioned?

It’s coming up that the in-line 4 cyclinder 2.0 litre turbo is named m133.. this may be wrong! But yes I’m wondering how strong the a45 engines are regarding tuning.. how far can the internals go and gearbox etc...

You can map them to 420-430ish without doing anything mechanically just an ECU map, beyond that you'll chase small gains for a ever larger outlays.

Renntech, DMS, MSL are obvious tuners with maps that haven't had issues reported.

An upgraded turbo from TTE roughly £3k for 450/460hp beyond that and it is the world of bespoke mods.. TBH most of the aftermarket upgrades e.g. airbox, downpipe, exhaust don't actually offer any benefits vs a decent ECU map.

Water/Meth injection and a serious budget (6k+) can see 500hp, not sure how many there are running such setups or the long term reliability.

The early (2013-2014) ones had bad batch of turbo's but these should all been captured by a MB warranty campaign, the post '15 facelifts have gearbox issues but it's random as to weather the box will go wrong or not, mapping / modding doesn't seem to related to box failures. So far actual engine failures do not appear to have been reported.

If you want to project to fiddle with modding wise get a RS3 or a Golf R which both have far more active tuning scenes.
