I'm in the process of building a set of B1B Quickspool and B2 twins and was wondering which external wastegate to use. I want to be able to tune my twins and really need some advise. I will be using mach 3 edm's for daily drivers and mach 6's for competition. I hope soon to have a Diesel Dynamics cam and Formula 1 O-ringed and ported head. Any suggestions on wastegate type, size, specifications, and vendor would be would be greatly appreciated.

needs a bigger spring or a remote controller...

I'm going to use the Turbonetics Racegate (42mm). I bought a nice used one on eBay. [My twins will be HX35/40-12 hybrid & Garrett TV71.]

I would go with a 46mm Tial. I have had good luck with Tial. If you think you need a bigger wastegate look at the new turbonetics NewGen.
