they have told me they can mod my existing vnt turb to make it flow more air and they have also told me that i will indeed see a good gain in bhp. my current vnt is a gt2256v which is a 22mm rear turbine wheel and a 56mm front comp wheel. What they have told me is there is no need to go bigger on the front comp housing as i will then start gaining lag even with a ported shroud which is the reason why i have this turbo for minimal lag but to make good power what they have offered me is a new 25mm rear wheel and a 60mm front wheel new 360 thrust bearing all machining work to housings and rebuild it for £495+vat unless i go there and do a cash deal
will take about a week and they think i could make up to 40-60 bhp gain with these new wheels over the ones that are in there
