Yup. Twins is something PNM/NM35s will never achieve. There is something called a driveshaft that prohibits that kind of fun
Simple - RWD- get a TT kit, awd get a single turbo kit. Or supercharge to to be different?
Plenty of stuff out there to build a VQ35de. Thankfully parts are sort of cheap and plentiful thanks to the US market. I was looking at Tomei conrods today for ~$900 USD, add some Cosworth 9.0:1 pistons (not so cheap), studs, uprated gaskets, bearings and slap together. Make 500hp on 14psi, and find a plentiful supply of re5r05a.
