These hybrids are up for £1000.
A single kit is going to cost you a minmum of £2000, even more at the moment with the US exchange rate as it is.
Then factor in the extras not included in turbo kits such as DBB water feed lines and that £1000 is a hell of a lot cheaper than any reputable single kit.
I agree that a single kit is quicker to fit but it won't be £1500 cheaper....then factor in the mapping differences too.
I have had a set of turbotechnics turbos on my car for 40,000 and they have never ever missed a beat or shedded a puff of smoke.
I you are looking for sub 480bhp flywheel power, you want to keep insurance cheap then hybrids are great. I personally love the pull of a seq twin setup and that lazy sub 3000rpm surge is great.
I have never been in another TT on stock based turbos that pulls as hard as mine and that includes stock, BPU and vvti bpu's in both manual and auto and I only run 1.15bar. So...naturally I don't agree with the "hybrid slating" and making apples to orange comparisons of drag racing times between two different cars is no fair way to draw conclusions.
Just my 2 pence
