Well, here's my question..... lets say you had a stock s13, and I wanted to upgrade my fuel. I'm wondering mostly what fuel management to use??? I'm thinking of running this set up:

Walbro 255, ?? size injectors pref. top feed, FPR, Fuel rail, and Wide band O2 in the future

Allthough I don't have the money for a stand alone yet, and this is just an idea but I'm used to DSM and Subaru STI's

is it the same basic set up in the 240 S13??

Super AFC? VPC? F-Con?

I have Megan headers, down pipe and cat delete, also an intake so far...

Thanks...

John

 

safc is pretty good solution..
370 injectors may be over kill with out FI or HCR... an Exhaust would give you good benefits as well with your set up, as well as would a lightened flywheel, pulleys, upgraded cams... ect ect.. The posibilities are endless pretty much.

There are several builds going on in the present.. yours is pretty similar to mine... I am using 91 cams, 89 pistons and rings, complete rebuild, FPR, OBX Header, cat delete, 2.75 exhaust, intake, 370 cc SR injectors, Project Silvia fuel rail, FPR, a walbro 255, and a SAFC for tuning with a Wideband to be added a little later when i have more money!!
Also for tuning.. standalones dont have to be that expensive.. check out Megasquirt.. im am really thinking about building one!! Tons of posibilities.. or you can think about rechipping your ecu.. lots of options!
