I have a 95 civic with a d16z6, greddy turbo kit( tdo4-15g, vortek fmu, missing link map bypass, VAFC) stock fuel system, and Im running a 18-9-3" intercooler. Greddy sends the turbo at 4.5psi im going to run 8 but im seeing lean a about 6. I know I need a fuel pump and maby some h22 injecters. but I whould like some input from you guys that have run turbo singel cams.
i havent run a turbo SOHC, but i think hitting that psi or higher is gonna take more than H22 injectors. i might be wrong, but i think DSM 450s with a VAFC would be best for you. (still need the fuel pump though)
if the h22 injectors are 310cc though(as i just found out) it might be enough to fuel your car. but either way i would still go for a VAFC

I'd suggest getting some DSM 450cc's(they're pretty cheap so it's not a big deal) and removing the FMU/missing link. You can set the VAFC to compensate for the bigger injectors running on a stock map. It's better than trying to inaccurately flood the car with fuel according to boost. If you really want a good set up, look into chipping your ECU and running Uberdata.

i would go with a vafc also good point but when i did turbo on my teg i also had a problem with the fuel at 6k i had an safc because it was an ls but after i got an intank fuel pump and some bigger injectors it ran fine

most people sell 450cc DSM injectors for 60 bucks. my brother runs them with a safc II and runs 12lbs fine. he got rid of his fmu and missing link. you should do that.

ran 12 psi for a year with the greddy blue box that came with the kit.... then, unexpectadly one morning... CLANK. I'm not there yet, but I'm looking at uberdata or something similar. simplify things a little, sounds like you have WAY to many bandaids on there now...

oh, and I never had any problem with the map, or CEL's, but the blue box mods the signal between the map and ecu...

Its not that much different then a dual overhead cam, many people have told you DSM injectors and a fuel pump. If you dont want to do it that way, get h22 injectors and dont come running to us when you run lean and toasted your motor. If I was you I would leave it like it is, and get a fuel pump. Then do some dyno tuning to watch your fuel ratio. If you still need injectiors then you can get 450's for 60 bucks. However getting them to run right (~33%) correction can sometimes throw your timing off.

shinnco---yeah my brother was a bit off. i actaully didnt get rid of my missing link. someone told me i could and i tried it because they said the safc would compensate but i still threw a map sensor code and it bogged down so much it stalled if i let off the gas. ditch the fmu but keep the missing link. definitely get the 255 fuel pump though. unless you use uberdata or hondata with a 3 bar map sensor its the only way to keep your ecu from freaking out when you hit a certain level of boost. def retard timing though. i know someone was selling dsm's on this site for 60 bucks but he's in the springs with me. i cant remember his name on the board but ill look for it. im sure you can find some easily.

I really think a d series wasn't meant to be turbo'ed it's like a person doing herion, the rods are as big as a guys pinkey once you hit boost your done for. That's the first thing I would up grade before anything.

Well ofcourse it's not specifically made to be turbo'd but you can do so and still have a reliable engine. I've been runing 7psi on my 140k mile d16a6 for a full year now so I'm one to disagree with the idea boosting them is a bad idea. Sure, once you start reaching 9+psi you might be pushing your luck(especially if you motor has quite a few miles) but that's part of deal when pushing stock D-Series that far. Plus they are cheap. :P

^^ ya I just rebulit mine and I see alot of the d's doing 10+ all day long Some runing 12psi on stock rods and pistons. So if you think d's cant be fast your retarted and your going to get your ass wiped by a lot of cars with the littel pinkey sized rods....

im running my D series turbo at 8 psi. Turning pretty nice numbers on the track.
Just remember though, you are still driving a Honda Civic with a D16. Take your time and do things right. Dont push your luck or you will be looking at spending far more than you wished, and may end with a car sitting in your garage.
