Hi! I have a ‘92 740+T with your standard 15g swap running on about 5psi to keep things safe. Everything is pretty much stock excluding a 2” exhaust and aftermarket air filter. I’d like to eventually crank things up a bit but want to do so in a reliable manner. Im already planning on getting ARP head studs and a Cometic metal head gasket to keep things nice n tight but I’m curious what sort of injectors I should run? I was considering running some Deatschwerks 650cc injectors but, this being my first turbocharged car, I’m not sure how much boost 650cc’s can handle. I read that a stock b230ft with a 13c turbo can reliably run 12-13psi so I’m not necessarily afraid of pushing my engine with this 15g but I’d rather not accidentally detonate my first 740. Since this will still be a daily driver I’m not trying to run it on 20psi all the time; but I’d like to be able to crank it up reliably when wanted. Also how much can the stock fuel rail handle? Or should I just upgrade that too while I’m at it..? If there’s anything else I’m missing please don’t be afraid to let me know! This is my still my first year owning this car and I’m trying to learn as much as possible and do this in the most correct way that I can. Thanks !
