Hi all,
I'm hoping someone can help me out.
I'm doing some upgrades on a mates R32. It's an Rb20 and have done some mods to it.
Basic Mod list;
- GT3071, .63 rear housing external gate.
- Tial 32mm gate
- Turbosmart FPR800 fuel reg
- Turbosmart Dual port BOV
I made the following stuff for it;
- Custom exhaust manifold, top mount. Using 32mm steam pipe.
- Custom 3.5" dump with 2" screamer into 3" system with metal cat.
- 3L surge tank with an 044 pump.
- Also made some intercooler piping for the bay to accommodate the top mount manifold.
My question is, what size injectors do you guys recommend?
I was thinking about some Seimens 600cc, Or should I step it up to 800cc. As soon as this motor pops, an RB25 is going in, with a fabricated inlet manifold. I was planning on getting some fuel rail extruding and making a fuel rail for it as well.
Also, is the RB25 injector spacing the same as the RB20? ie, can I use an RB25 fuel rail, or is the spacinf different?
Thanks in advance.
