I'll start by saying I couldn't quite find anything on this so I'd appreciate any help. I have a stock 96 Civic LX (y7).... I've never really liked the fuel inywction system on it (can someone tell me why the 96 LX comes with this kind of system instead of the PGFM???). A friend of mine has a full pgfm admission he's selling to me cheap, with everything on it (throttle, inyectors, fuel rail, regulator, tps, etc). I am seriously considering going for it and swapping that inyection system but wanted some guidance first. Is it a simple as it sounds process? Will I really notice any difference or is it all in my head? Any suggestions will be appreciated.

What are you trying to gain the way you're explaining it I have no real clue what you mean. are you looking for bigger/lower CC injectors ??

emv1031

Yeah sorry.... Well I'm looking for maybe better acceleration and fuel consumption (and yes I know I may be way off). I also have a 94 Dx, which is really the wife's, and the consumption on it compared to my 96 differs too much... yes I know mine is 1.6L vs 1.5l on the 94, and understand that maintenance as far as inyectors, sparkplugs, timing etc also affect... But still, feels too different.... I guess I'm also looking to find out if putting a PGFM FI on the 96 LX do ANY difference whatsoever in any regards or am I better off just using the money for ribs and beer.

Thx again

still the way you're explaining it is rather confusing so in short you're trying to swap over the fuel system. 1.5 vs 1.6 won't be a noticeable factor I would recommend a FULL tune up on the car the money is better spent on that or on something else plus you'll run into having to splice in obd1 injector plugs not hard just a factor. Here's the fact: the injectors, pump both have the same CC/LPH in both of your cars. I would make a thread about low mpg on your car see what comes up but a full tune up would be helpful.

Just because it doesn't say PGM-FI on the intake manifold in big, shiny letters doesn't mean the car isn't PGM-FI. You already have PGM-FI. There's a lot more to it than just the D15B7 vs D16Y7, as well. The 5G (92-95) is noticeably lighter than the 6G (96-00).

Confirmed as above, you already have PGMFI. I think you are confusing the Y7 setup with the D15B2 from the 88-91 Civics which looks somewhat similar but has DPFI. If you end up using that intake setup you will have to reuse your throttle body (due to 3 wire IACV) and keep your injectors as the other injectors are 240cc vs 180cc (if its OBD1 then you'll have to make adjustments to your injector plugs anyways). You'll also have to swap over the throttle rotor from the new throttle body to your Y7 one. You won't net much power though so unless you just like projects or want to learn more about your car leave it stock. What is the intake manifold setup off of?

Just buy ribs and beer man.

And if you run 240cc injectors on the stock LX/DX ECU, your fuel mileage is going to get even worse, and you might just wash your cylinders out...

Beer and ribs it'll be then....

I really did know that the inyection system on the 96 is not the same as the 88-91 DPFI, but I did NOT know that it is PGFM... I honestly thought that what they did on the 96 was like a cross breed between the DPFI and the 92-95 PGFM... since the top part (where the filter goes) does look like the DPFI system, but there are 4 inyectors instead of two... of course I might be very very mistaken. I'll take the advice of a tune up then. Just so that I can understand better, can someone tell me the benefits of the y7 system vs the older PGFM system on the 92-95? Is it supposed to have better mpg, or is it just the same, just looks different?

btw, I didn't get much info on the intake, they just told me it works on the D15 and D16 all the same... here's a pic of it
Thanks

it is multi port. you have 4 injectors. it's just a different intake manifold setup. the throttle body is in the middle of the manifold versus 1 side.

I understand, pretty simple. Now question: a long time ago I had replaced the original filter assembly with an aftermarket K&N intake....but it seemed to me like there was way too much air coming in... whenever I took like a normal turn and wanted to accelerate after the turn or was driving slow and then stepped on the gas the car seemed to need a moment before responding.... I sold the intake and went back to the stock one, but always wondered if that had anything to do with the type of admission on the y7
