Non Sequential Conversion

[Martiny]

I think you can have whatever you like, if you spend enough money ! I dont see why it wouldnt be possible. Expensive, yes, but possible.

[John Yorke]

I think most people go non seq. to simplify the turbo controlls or have an inherant fault with them, the stock twins are available and cheap [200 - 400] as against any bespoke hi-bred twins would be ££££, at the end of the day the reason people go the single route is for the simplicity and its the cheaper option.
Trotter:
Think you might be confusing me or yourself:rolleyes: In stock form the turbos on your car run seq. [ie: 2nd turbo pre-spools whilst 1st turbo is boosting] Non seq. is the turbos modified so that they both spool together thus inducing additional lag. HTH
