Mitsubishi Galant Tuning tips

"Galantry is far from dead."

VR4 tuning

The Galant first appeared back in 1969. It was not until 1987 that a high powered version appeared with the 2.0 turbo engine producing 200 bhp.

When 

Looking at the high spec Galants we get to see the true potential for a Galant tuning project.

In order to compete in the WRC Mitsubishi produced the VR4 a highly tuned road going version using the 4G63 engine.

This formed the basis of the later Lancer Evo and is a popular engine choice for FTO owners.

The long run of this engine ensures that there are plenty of mods and tuning parts available for it. The engines are solid and reliable and can tolerate a lot of additional power until you need to make internal engine modifications.

 

The following mods are usually carried out by our members, decide how far you want to go before you begin.

Stage 1 mods: Exhaust, Panel air filter, Remap, lighter flywheel

Stage 2 mods: Fast road cam, ported and polished head, fuel injector & fuel pump upgrades, 

Stage 3 mods: Engine balancing, forced induction (turbo/supercharger), Internal engine upgrades (pistons/head/valves), competition cam.

The later VR4 in 1992, was kitted out with a more refined V6 engine fed by a twin turbo. With the full attention of Mitsubishi on the Lancer the Galant was relegated to be more of an executive saloon than a road burner.

The Galant become a "tour de force" in the WRC rally when Mitsubishi introduced the road going VR4 showing what tuning potential there is.

On the 1992 VR4 Galants we would strongly suggest that you upgrade the suspension to give a tighter handling ride (other years come with reasonably good suspension setups as standard).

By 1996 we saw Mitsubishi turn its attention back to the Galant VR-4 and they introduced a 2.5 litre V6 engine - the 6A13TT. This has to be the engine of choice as far as the tuner goes.

Avoid the tiptronic gearbox as this saps a lot of power from the wheels and go with a 5 or closer ratio 6 speed box instead. An estate or station wagon version of the VR4 was offered and was badged the Legnum, essential with the same running gear as the Galant.

VR4 tuning

In 2007 ralliart were let loose on the new Galant and obtained a stonking 260 bhp from the V6 engine.

This model revision from 2004 is a lot heavier than previous models so we would favour the early Galants as tuning projects. This is borne out by the large quantity of parts around.

On all turbo models you will make substantial power gains simply by getting the engine remapped.

Some owners swap the twin turbo setup for a larger turbo to make big power, although this setup is somewhat laggy low down.

Non VR4 model owners usually look to the VR4 parts bin for suitable upgrades. Engine swaps are popular with our Galant owners and when you have the turbo you get one of the best tuning bases around. If you have a standard Galant we would recommend that you uprate the brakes and suspension using VR4 spec replacements where available.

    This article waa well done. A lot of my club members like Mitsibishi and the VR4 looks amazing along with Legnum.

    I like the early EVOs too but I’m wary of Mitsubishi reliability but it sounds like 6A13TT is solid.
