Hi to all,
I'm pretty new here but I've been reading topics for a while in Forced Induction, and I saw some very interesting projects. I'm planning to do a SC build on my 7AFE, leaving the engine stock. The boost I'm looking for is about 10\11 psi and I'm planning to mount a small front air\air intercooler and eventually a water spray on it. The whole project will run around AEM FIC piggyback ECU, and Eaton M62 SC (mercedes spec with electric clutch) but obviously one of the biggest problems that I face is the ability of the stock injectors to follow the boost. I've read that stock "red top" 7afe injectors are rated 192 cc\min @3bar, and they seem small for a boost of 10 psi, aren't them? The possible choices, I've seen used in other builds, are: "Supra Green top" rated 312cc\min "Celica\MR2 Green top" rated 220cc\min and "indefinite rate" Ford Probe installed by the guy in this video. The question is: will stock injectors follow the boost till 10psi? Could be enough to upgrade the fuel pump and regulator with stock injectors? Thanks for your attention. p.s. sorry for my English, I'm from italy. pp.s. really nice forum and cars, keep on going!!!! -------------------- Black Celica Carlos Sainz, ST spoiler, 15'' tsw rims, Magnaflow exhaust from Italy

I'm planning to put the SC unit on the top of the alternator, probably it's not the best solution (longer pipings), but seems pretty straight thru.
Otherwise seems also a good idea to swap the position between alternator and SC (for piping needs) or just pull out the AC system and place the supercharger instead, but those solutions require much more extra welding and time than the simply "SC on top". Also I'm pretty concerned on the SC pulley: I'm going to make a "double" pulley (in alloy, ergal, iron... idk) and place it in place of the original alternator pulley, so engine will drive alternator, alternator will drive SC.. it doesn't seem a good idea to me but I can't see any other options instead, except putting a single belt covering both SC and alternator, but still faces the problem of not being able to choose the driving ratio of the SC. Talking about injectors: those Supra Green Top are plug and play? Thanks for the reply!
