[sairaag]

hello, I recently got a 240sx 1990 and an sr20 red top engine. I would like to put a t28 upgrade but I was wondering if I need to upgrade th fuel on the engine and put a fuel controller if so can you let me kow what type of injectors to get. thanks

What kind of boost are you planning on running?
550cc injectors and Safc should do the trick

10 or so it has a fmic and a walbro installed allrdy. was planning to get th ecu moded for a 500 instead of the afc. Would a dsm injector fit on the 240? because I have a set of 550cc and it would be nice if I can swap em out. I had an afc but sold it.

SR20 uses side feed with stock rail, IIRC.

Don't know about the DSM injectors.

I'd recommend getting 550cc to be safe. You start maxing out the stock 370's around 11-12ish PSI.

If your gonna go ahead and do a rom tune for this setup, you might as well get yourself a Z32 MAF too and have it tuned with that. So 550cc, T28 turbo and z32 maf...youll max out the turbo before the other 2.
