experience-challenged (i.e. n00b) questions again...

[wild.irish]

...fuel system now. Just wondering which brands to avoid if i need to pick up a fuel pump and injectors. so far I was concentrated on Venom. Anyone had any bad experience with them?

[ryanman]

I haven't heard anything too bad about Venom but there are much better choices. I have a Venom 2000 nitrous system and it works awesome although I also bought one of there Venom 400 "modules" and it was a heaping pile of shit. I won't ever buy anything Venom again.

Aeromotive pumps/filters and Denso injectors are my brands of choice.

Can't go wrong with Walbro fuel pumps. I had Precision Engineering Injectors in my Integra, never had a problem.

If he goes with a walbro won't he need a fuel presure regulator to control how much fuel he is adding? Or do they make close to stock pressure? Pardon if i worded that all f'd.

[rmcdaniels]

I use a Walbro 255 LPH fuel pump, cheap, gets the job done, and no problems so far. I use RC injectors, they are not cheap, but they are flow matched to within 1% and I've had no problems with them. RC is also real helpfull if you call them.

If the question is directed towards me, I have no idea what kind of car he has or what kind of setup so I have no clue what he needs. FWIW I've NEVER had an aftermarket FPR on any of my turbo Honda's. I think they are a big fat waste of $$, time, and energy.

All fuel injected cars have a fuel pressure regulator, it will work the same with the Walbro as with the stock pump. The advantage with a bigger pump isn't necessarily that it will make more pressure, but that it will flow more volume when bigger injectors and greater duty cycles are used that would use more fuel than a stock pump could supply.

Walbro pumps are pretty good also.

[floored4door]

the reason why i was wondering is I was having fuel problems with my civic, so the guy that i have working on my car recomended that I go with a larger fuel pump because he didn't think that the Stock fuel pump was providing enough fuel for my B18. He said I needed a FPR because to much fuel would drown my motor. So I basically didn't need this? The stock one would have worked fine?

I've seen cars making 600HP using the stock regulator. Depending on how you manage your fuel, stock fuel pressure should be fine. Plus bigger fuel pumps don't necessarily make any more pressure than a stock pump, they just maintain that pressure at higher flow rates.

Walbros are also pretty noisy. Some people dont mind. Those that do prolly go for Supra TT fuel pumps.

I'm no Honda tech but a higher capacity fuel pump is not going to fix or take care of very many issues, if any issues at all. Talk to Tobi about your issues if problems persist and the current mechanic can't figure it out.

I had a walbro in my old Talon, they definately make a bit of noise. You could hear it inside the car, though I think there was an issue in the chargin system somwhere that made it a bit extra loud. I have another walbro sitting here for my VR-4, a faint whine from the back of the car isn't really a large concern to me. Cheap, effecient and reliable :)

For injectors I'm using RC, I would stick to RC, PTE (modified Delphi injectors) or Denso. They all come flow matched to 1%, as I recall, and all are very reputable for top performance.

[doctorstupid]

Forgot to mention that a Walbro is about 1/3 the cost of its silent counterpart: poopra pump.

That was before I knew about toby. But the problem didn't have anything to do with my fuel supply. I had a 2ndary fuel cut switch inline with the power wire to my fuel pump and the switch went bad causing my fuel pump to only be working half assed. It was wierd, my friend and I were stumpped as to what was going on. He had a dream that it was the switch (oddly enough) I pulled out the switch and it fixed the problem. Crazy shit!

[wild.irish]

Wow, guys, thanks! that's a nice chunk of information for me to read!

in the meantime, there was a remark about which car it will be used on (i thought my car was famous by now, guess not ;) ) - this is for F22B2 (94 accord).

[Brandon]

+1 for walbro 255 and RC injectors, that's what im using with no problems so far

[wild.irish]

cool, so i'm going with Walbro and RC injectors.

Now, not to whore performance zone with numerous n00b questions, i'll just stick to this thread.
Attention: another question!

Are RS-R ExMag exhaust systems really quiet and would be suitable to handle boost? does anyone have experience with them? I never heard/saw them on the street, and didn't hear about them till today, but they do look respectable and claim to be silent. any opinions?

[rmcdaniels]

Thermal Research is the best I've seen, but never tried RS-R. Thermal 3" turbo exhaust is quiet and very well made.

[wild.irish]

neat. it even looks kinda close to stock

damn these things are expensive ;)

[STIBungy]

You sure that's a turbo catback? Piping looks small.

[wild.irish]

it seemed so to you too? yeah, i'm not sure, i thought it's kinda narrow. i was going to ask them about specs anyway, but i'm not going to buy it immediately.

[rmcdaniels]

It looks like they don't make the 3" turbo system for an Accord, just for a Civic. That pic is the CL system.

[S15SiLVia]

which rs-r exhaust are we talking about here? If its the stock looking one then that one is pretty quiet. probably too quiet for some. If its the canister, i wouldn't count that as quiet.

[wild.irish]

the one like this: http://www.prostreetonline.com/buy/rsr_exmag_catbacks/
they have a couple of other series, but one is not available for accords, and another is probably the canister you're talking about:
http://www.prostreetonline.com/buy/rsr_exmag_gtii_catbacks/

so yeah, i was looking at the stock-looking one, black one, not canister.

[rmcdaniels]

That one doesn't look like it's 3" either, I can't find one for Accords. The Thermal CL is $519, and probably either of those exhausts would work fine. Also make sure you get the same size downpipe and cat.

[S15SiLVia]

The application for the accord is 60mm piping. so thats about 2.5"

[HONDA GHANDI]

I sort of agree with Mark and sort of disagree. FPRs are for the most part a bling item under the hood but with a car that needs some tuning a lot of small issues can be fixed with a small tweek on the FPR. It is easier to adjust a AF ratio that is slightly high or low across the board with pressure instead of retuning an entire map in an AFC or Hondata. Plus when I go to lower states for racing and dont have a dyno to retune my car I know that 1.5 turns on my FPR will give me about 2 points of AF for a better mixture at sea level.

FLoored- A fuel pump change in a car will only change the flow potential in GPH. To change the pressure the FPR has to be changed or adjusted. Just think of it like this, the pump and lines are responsible for the amount of fuel supplied to the injectors, the FPR is responsible for the fuel pressure at the injectors. It is way more complicated than that but that simple rule will help you understand the principle.

[STIBungy]

Hehe, that's how I got my civic running right after I bought it. Turned the fuel pressure down from 50psi to 34psi.

I was being obnoxious, all done for now, although it really didn't look that huge at 1400x1050.
