270cc. The injectors as is should peak at around 170-180whp or so I believe. Would also depend on the duty cycle and whether an FMU or what not was involved if for a boosted application. For the rail itself, i’m not sure. ---

thanx a lot bro what fuel pump and injectors do u use in your 93 ka24det, b/c i am doing up the exact same motor 1993 ka24de, any info would be wicked like size and flow, my application will prob include a tubular exhaust manifold, t3/t4 turbonetix turbo, cams, valves and mabe pistons and rodes.

valves are the essential upgrade for KA-T, good call. I wouldnt worry about upgrading your rodes tho, the stock rodes are good for at least 300 RWHPOMG ---

I am looking for anywhere between 200-400 hp to the wheels I’m still using the 270’s and a Walbro 255 fuel pump with an 8:1 FMU to keep things rich under boost. Not really the best setup at all by any means, but i’m only running low boost (5-7 PSI) for now. Ideally you’d want 370-550cc injectors and an S-AFC or E-manage to control them. Other ideas would be a different MAF to flow more (usually Z32), a wideband to monitor accurate A/F ratios, or an ECU upgrade. You’ll need time & research to piece it all together so take your time and only start when everything is totally ready. ---
