“Mate, I took my car to a tuning shop my mate knows, and they trashed my turbo!”

We hear this all the time. But let’s be real most turbos that “die” were already on their last legs before they hit the dyno or before the other tuner touched them. I am very shy about taking on a job where the customer slates the other tuner even where I dislike the bloke!

I don’t mean AdBlue or EGR solutions going wrong etc. But when the car comes in and they say my turbo blew up because of XYZ tuner on a stage 2.

The customer might not have been made aware of the tuning risks by the other tuner, but ultimately they took in a car with the miles and age on it asking for a miracle. This is why every tune we do, we have a written disclaimer and fact sheet where we try and raise awareness before we do anything! It is also why we data log on the road and dyno especially where its stage 3 and above as I want to try and make sure what we've done works. We cannot eliminate mechanical risks without stripping the engine and forging it, but we can try and minimise them.

Chasing big power with a larger turbo? You’d better know what you’re getting into. This isn’t a bolt-on air filter or a quick remap.
A big turbo means compromises, risks, and a good chance of exposing every weak spot in your setup especially if your engine’s got some miles on it. I appreciate lots of firms sell stuff which looks like its a bolt on and quick remap and its done. But what about 40K miles later, what's it going to be running like?

Take that “bulletproof” motor everyone brags about. Sounds great, until you realize it’s got 120,000 miles, a sketchy service history, and a diet of cheap oil. That’s not bulletproof that’s a breakdown waiting to happen.

And those second-hand parts you’re eyeing? “They worked fine on the donor car”? Come on. That’s a gamble, and deep down, you know it.

We see it constantly daily drivers getting massive turbos slapped on with all the usual bits: intercoolers, injectors, manifolds, fuel pumps. Why? Someone saw a mental dyno graph or a quick run at Santa Pod. But what they don’t see is the work it takes to make that setup reliable, drivable, and not self-destruct in a month.

The payoff’s obvious: more torque, more boost, big grins. But step outside the factory turbo’s limits, and “safe power” gets blurry fast. Stage 1? Easy. Stage 2? Manageable. Big turbo?
You’re in deep now. It’s not just about the tune it’s the condition of your engine, the quality of your parts, and whether you’re ready for things to go wrong.

“Safe power” sounds nice, but it’s not universal. What’s safe for a forged engine with standalone management isn’t safe for a 150,000-mile block with worn rings and a wobbly turbo shaft. No amount of mapping fixes mechanical wear.

Then there’s drivability. Big turbos mean lag. Pair one with an oversized intercooler and a dodgy map, and your car can feel like it’s dragging a trailer when you’re off-boost.

We get messages every week from people across the UK moaning their car now drives like garbage. “No, torque,” “feels dead,” “worse than stock.” Sometimes it’s not even the tuner’s fault—it’s just a bad match for how you use the car.

Don’t get me wrong—big turbos can be awesome. If your car’s a weekend toy or a drag strip monster, go for it. Build it right. But if it’s your daily your ride to work, school runs, or slogging through winter traffic that 600BHP top-mount might leave you cursing.

And while some tuning shops get a bad rap, let’s be fair: they don’t always “kill” turbos. Show up with a knackered, smoking unit and demand more boost?

It’s gonna die, no matter who’s behind the laptop. That’s not a bad tune—that’s a bad plan.

Just because a turbo kit exists doesn’t mean it’s right for your car. What screams on a drag build or a demo car might suck for daily driving. There’s a big difference between chasing dyno numbers and building something that works on the road.

So, if you’re set on a big turbo, be real with yourself. Get your engine properly checked. Budget for the right supporting mods. Accept that stuff might break. And work with someone who knows what they’re doing . Hopefully they would have done other similar mods, but if your idea is really out there remember to do it right its going to take more than half a day on the dyno!

Before you start buying shiny bits, take a breath. What’s the goal? DIY or pro help? If tuning’s not your thing, talk to someone who’s done it before—us or another solid outfit—before you go wild on eBay. It’ll save you cash, headaches, and a whole lot of swearing.
