![]() The crank, if the stronger forged version has been able to handle around 700hp.Įarly engine parts were not as strong, so replacing with the later forged components can provide a cost effective upgrade, and these can be Cryo treated to further improve their resilience and wear resistance. Limits on stock internals is around 400hp for most turbo variants of the 4G63 and we often see 500hp tuned versions but would strongly recommend a stronger rods and pistons around this point. We won't be swayed by popular 4G63 mods, they need to be cost effective. The greatest 4G63 mods on an engine are obviously the ones that give the best value for money. Tuning the Mitsubishi 4G63 and best 4G63 performance parts. The engine is very smooth running, primarily due to the twin balancing shafts Mitsubishi fitted to absorb vibrations.

We've seen tuners pushing over 1000hp from the 4G63 which, although prohibitively expensive it does give you inspiration and shows how capable these blocks are. ![]() They are solid and reliable and give good returns for pretty much every mod you throw at it. When Rallyart took it and tuned it we saw a phenomenally powerful 2.0 4 cylinder engine.
