500whp fuel setup and twin disc questions - Zilvia.net Forums | Nissan 240SX (Silvia) and Z (Fairlady) Car Forum

Looking to finish my build here soon and im needing opinions about what to do about fuel. The basics are a 9:1 stock bore sr, gtx3071, using e85. Can anybody point me in the right direction of a set of side feed 1000cc injectors that are not redrills. I think those and a rewired 255 pump should get it done on a stock line and z32 fuel filter but correct me if I'm wrong.

Also looking at twin disc clutches. Don't mind something used as it's rebuildable but can the os giken stuff handle 450 lb/ft or more? Also looking at carbonetics aswell but need more options.

Honestly, never a fan of Walbros...sounds like you have alot of money riding on this build. I say go for bosch 044s.

Os Giken TS2B should be more than capable for the job.

Totally forgot about the 044. That would easily get the job done, thanks. I'll take a look at the clutch

Or a Walbro 400 intank

Mazworx top feed fuel rail, and ID1000s are probably your best option. I don't think you'll find side feeds manufactured in 1000cc. Good luck!

My friend is running Five-o's 1000cc injectors (plug and play, stock SR pigtail), circuit sports sidefeed fuel rail, Aeromotive 355lph in tank, Walbro 255 in-line, 3/8 fuel lines, stock fuel tank, two relays (each one for each fuel pump, direct battery voltage)

He just hit 510whp on E85 with GT3076R @ 28psi, 87mm bore. Built head (oversized valves, port and polish, valve angle job, etc.)
