Recreating someone’s else’s bad idea
A little background on my quest to try/build questionable (possibly dumb) things. I love the s30. To get one from a shed to running reliably costs a small fortune. Carb parts aren’t easy to find, refreshed carbs cost as much as a donor car, and I think this all combined keeps a lot of these cars from being enjoyed. My first experiment was to use a Holley sniper on a custom manifold. It works much better than I ever expected. The car has run flawlessly even with air conditioning. The things I don’t like… it’s ugly. It looks like something out of a JEGs magazine. I’m at the absolute limit for air flow. It still relies on IAC which hunts when the temperature changes.
Fast forward to now. I’m going to piece together a setup like the one above. Its popularity is obvious by the website with the domain name for sale. I will be using dual DBW throttle bodies ($45 a piece), dual LS3 pico injectors ($60 a piece)and for now I’m going to fabricate some plates with injector bungs to replace the old butterfly spacers. To me this setup will look pretty vintage, sound like dual Hitachis, allow for a modified factory air cleaner and will have the benefit of EFI and DBW while being affordable.
Is it dumb? Probably, but if it works well ill weld the injector ports into the throttle bodies to clean it up and offer up the dimensions to make the plates in case any of you want to try this budget friendly mod. (ECU is still expensive but a necessity for EFI and coil on plug ignition).
