We’ve created the ultimate guide on the B230 19T – from engine specs to performance tips, everything explained in easy English.
The B230 19T is more than just a combination of numbers and letters. It’s a powerful turbocharged setup using the reliable Volvo B230 engine and the performance-packed 19T turbocharger. This combo is known for producing impressive horsepower with the right tuning – making it perfect for those who want to take their car’s performance to the next level.
What is the B230 19T?
Breaking Down the Name
Let’s start by understanding the name. The B230 refers to Volvo’s 2.3-liter, 4-cylinder redblock engine, widely used in the 1980s and 1990s. It’s a cast-iron block known for its strength, durability, and potential for tuning.
The 19T part refers to the Mitsubishi TD04HL-19T turbocharger. This is one of the largest turbo variants from the TD04 family, often found in high-performance Volvo models or used as an upgrade by enthusiasts.
When you combine the Volvo B230 engine with a 19T turbo, you get a setup that delivers reliable power, excellent boost, and great tuning flexibility.
B230 Engine Overview
A Durable Foundation
The B230 engine is known for being nearly bulletproof. It has a cast-iron block, forged steel crankshaft, and simple mechanics. Because of its solid design, it can handle high boost pressures when modified properly.
Volvo produced several versions of the B230, including:
- B230F – Naturally aspirated.
- B230FT – Turbocharged with lower compression pistons.
- B230FK – A low-pressure turbo version.
Most tuners prefer the B230FT version as the base for the 19T setup due to its factory turbo compatibility.
What is the 19T Turbocharger?
Turbo Specs and Performance
The TD04HL-19T turbocharger is part of Mitsubishi’s TD04 family. It features:
- 19T compressor wheel – Larger than standard 13T or 15G wheels.
- HL (High-Flow) turbine – Offers better exhaust flow and quicker spool-up.
- Internal wastegate – Keeps the setup compact and efficient.
With proper tuning, a 19T turbo can produce up to 300+ horsepower when paired with a built B230 engine.
Benefits of the 19T Upgrade
Why do enthusiasts choose the 19T for their B230 engine?
- Fast spool-up – Quick power delivery at lower RPMs.
- High top-end power – Keeps pulling strong even at high speeds.
- OEM fitment – Easily bolts onto many Volvo turbo manifolds.
- Affordable upgrade – Often sourced from other Volvo models.
How to Build a B230 19T Setup
Step 1 – Choose the Right B230 Block
Start with a B230FT block, ideally from 1990 and newer. These blocks have stronger piston oil squirters and better cylinder wall support.
Step 2 – Install the 19T Turbo
You can find the 19T from:
- Volvo S60R or V70R
- Upgraded TD04HL turbos from turbo specialists
Mount it to the stock turbo manifold using a TD04 flange, and ensure your oil lines and coolant lines are properly connected.
Step 3 – Fuel System Upgrades
A larger turbo needs more fuel. Consider:
- Bigger fuel injectors (e.g., 440cc or higher)
- High-flow fuel pump (like Walbro 255)
- Adjustable fuel pressure regulator
Step 4 – ECU Tuning
A custom tune is essential. Either go with:
- Chipped LH2.4 ECU for Volvo platforms
- Standalone ECU like MegaSquirt for full control
This allows you to adjust boost, fuel maps, and ignition timing for maximum power and engine safety.
Performance Expectations of B230 19T
With the right supporting mods, here’s what you can expect:
- Horsepower: 250 to 350 HP
- Torque: 300+ lb-ft
- 0–60 mph: As quick as 5 seconds (in lightweight builds)
- Top speed: 130–150 mph depending on gearing
All this while keeping the engine relatively reliable with stock internals up to a point!
