Yeah i would like to get my turbo highflowed someday soon, but the question is. When i send it in, should i pull the 45v2 compressor housing off and put it with the op6 rear housing or is it better with the 21U rear house, any advantages or disadvantages with either combination. Or should i just call hypergear and ask them what they would reccomend, as its them that will be doing the work?
