Stock honda fuel pressures?

[shepherd79]

Does anyone knows what are the stock honda fuel pressures?
i am trying to figure out if i can adapt another fuel regulator from another honda.
i am too cheap to buy adjustible fuel pressure regulator.

[1988starter]

I believe it is between 35-40

[AccordEpicenter]

specifically 36-37... at wot with no vacuum it can rise to 40+

[guaynabo89]

36-42 psi for 87 lxi

[shepherd79]

no no, i mean what is the fuel ressure for b16, B18C5, H22 and so on. high output engines.

[k-roy]

I do know that the H22 in stock form is 33-40 psi if that helps.

So it looks like you can adapt a regualtor if you get all the fittings right.

[AccordEpicenter]

they are all very close

yo Alex, i got one. it was only 60 bux from Summit. Its easy to put it on and u wont have to worry about anything else. Get that dude. It will be much easier since it adapts to the stock regulator bottom.

[shepherd79]

yeah i saw that one. it is made by B&M, right? i can get one on ebay for $50. the only problem is i still have to get fuel presure gauge to adjust it.
i was looking through chiltons manual and i found that 92-93 accord had fuel pressure 40-47psi. i got one, and it fits just like the stock honda fuel pressure. i just have to get new o-ring.
now i need bigger fuel injectors but that shouldn't be a problem. i found NA supra at the JY. it is going to be a bitch to remove them.

[smufguy]

so you are saying that the Supra injectors should fit ours? whats the flow rate on em? you got a high volume pump? I got mine cause Chris (Civteck) had his B16 in the 3g i have now and had a high volume pump and mine was runnign way too rich which gave me around 20 miles a galon and idled like crap. Now im getting around 27 miles a gallon and idles real smooth.

My injector is leaking and seems like autozone, national auto parts, pep boys and napa around my house dont have a parts list and thereby stock of the O-ring kit for the injectors. I have to visit the junkyard tomorrow. :D

[shepherd79]

i don't know what the flow rate for the supra injectors, but i am sure it is a lot more than stock accord. combination of 86-87 prelude ECU, 4g injectors and 4g pressure regulator gave me nice power feel through out the RPM range especially on the top.

[smufguy]

interesting what about using stock ECU? I was thinking of getting the 3rd gen lude ecu (The one on the passenger side floor pan) but shit was bulky and i could not steal it. I might try it tomorrow. BUt yeah i wanna see how far our ECU would go to adapt for the extra fuel flow.

[shepherd79]

i don't think you can use 3rd gen lude ECU.

[smufguy]

then why just the last two years of the 2nd gen lude? the 2.0si ? Hm...... that should be interesting then.

[shepherd79]

the 2nd gen lude had the same engine as in our cars. if you look at majestic website the part number for accord ECU and prelude ECU is diff.
the only problem is that prelude ECU will only work with 86-87 accord, due to diff style idle correction, diff intake manifold and so on.

[smufguy]

but the 3rd gen lude system is similar to the 88-89 efi system tho. so it wont work still? damn that sucks

[cdixon311]

I can't remember what magazine or even what company it was, but they were selling an adjustable fuel pump (about 40 to either 70 or 80 psi adjustable) for 50 bucks. I was thinking about getting one when I do my turbo in the all too distant future.
