turbo's and carbs

If using suck through you can use any carb, if using blow through anything other than very gentle pressure can cause issues with sealing around the butterfly shaft, if extreme enough it can also flatten plastic floats due to the pressure.
Suck through where the carb is before the turbo has advantages.

suck through works as a reasonable extra bit of intercooler for the charge air, but TBH it has plenty of other problems that more than cancel that out, including the fuel dropping out into the turbo compressor housing when cold etc.
Id avoid suck through use TBH
Most carbs will handle a reasonable amount of blow through, SU's are available to do it, webbers and dellortos too (lotus use the dellorto for blow through)
I still wouldnt though, ever, FI is the way forward without a doubt at 6 quid a gallon for fuel!
