The B204/B234: SAAB's Over-Engineered Turbo Monster

Forged from cold Swedish steel and built to handle boost like no other, the Saab B204/B234 is one of the most overengineered 4-cylinder turbo engines ever made. Tuners call it “indestructible,” junkyards call it “cheap,” and car enthusiasts call it one of the greatest forgotten performance engines of all time.

In this PistonPop deep dive, we uncover the full story behind Saab’s legendary B204 and B234 engines — from their origins in the late 1980s, to their insane strength, to the global cult following they gained after Saab collapsed.

We explore:
🔧 How Saab engineered the B234 from the ground up
🔧 Why the B204 became a tuner favorite
🔧 The stock internals that let them handle up to 400+ hp
🔧 How these engines ended up swapped into BMWs, Opels, Nissans, and more
🔧 Why the later B205/B235 couldn’t match the originals

This is the forgotten tale of an engine so tough… it often outlived the cars it came in.
