As you may have seen from my other thread, I will be carrying out a 1.8 zetec turbo conversion as a gap fill in my car...I have been looking into decompression plates and came across a few people who have used VAG 1.8t pistons as they are forged and meant to be good for some serious HP, which in my engine they should be fine as im only looking for 180hp or there abouts

Does anyone know what compression ratio you end up with roughly? And doing it this way, can we do away with a de-compression plate?

Im basically building the engine for as cheap as I can and can get the pistons for free so it will only cost me the machining work and boring the block out slightly

Thank you for any help
