Reason i say not a daily driver is that although they not unreliable as such, they are lil bit tempramental and as they totally different to normal engines in every bloody respect it can be a pain if got lil problems as local folk wont be able to fix easy.

Single turbo conversion isnt laggy on one of them, rotory engines create so much exhaust gas they spin up a 1000bhp turbos with relative ease- Ive been in tons of Rx7s with HKS T51s etc and they not even remotley laggy.

Just the standard sequential twin turbo setup is so smooth youd barely realise its turbod.
