I'm now running standard cvh n it's slow my mk4 diesel golf out pulls it I have cossie management n big inter cooler n a 4x4 hybrid turbo running 1 bar and a real nice head it's just to slow

So I'm wanting another forged engine so do I rebuild my forged 2.1 Zvh or do build a forged cvh.

When my Zvh was running it fucking pulled like a train so thoughts guys cheers
