hey u got an email matt
The main problems I found with the F-MAX kit are the manifold, which is not even comparable to any Rev Hard manifold. Design, quality, construction, etc...and the fuel system, those 2 extra injectors places before the throttle body...I woudln't do that on my car. Adding two injectors is a poor replacement for actually upgrading the stock ones. The two injectors sit in front of the throttle body, and the fuel is not dispersed equally. The only way to ensure equal dispersion is to have one injector per cylinder, like stock. If that weren't the case, Honda would have just thrown one big high flow injector in from of the throttle body, and let it saturate the intake manifold.
As well, as good as the stock intake manifolds design is, it is not designed to have fuel injected into it. The injectors are placed where they are places by the factory for a reason. Even though the stock intake manifold is designed with a semi-rough surface, which allows air pockets to jump and keep fuel from settling, the design was not made to accomodate 2 injectors coming at it. The design was intended for NO fuel whatsoever being there.
There is no replacement for upgrading the stock ones.
All of the kits use the same basic setups...turbo, piping, intercooler...etc...But the manifold designs, the fuel systems, etc...are usually the variables.
I think the Rev Hard system comes with an FMU and an in line fuel pump...but even that, I would upgrade to a holley in tank.
From what I have studied, the Rev Hard is the best all around kit, and it has the best dyno proven results...

hey, i'm running a b16a2 from a 95 sir2... got a set of crower stage 3 race cams, a set of the crower dual valve springs and titanium retainers, a set of dc sports cam gears, block guard,venom vcn2k setup(not installed yet) test pipe, dc sport 4-1 header, and a dc sports catback (along with a no name intake from autozone, only got it since the intake on the car when i bought it was raggedy as all get out...) i'm looking at chunking the 4-1 in favor of a turbo, i know, i know, the cams have major overlap, but i figure if i adnace the exhaust and retard the intake a few degress and tune form there, between that, my vafc form apexi and the back pressure caused by air stacking in the primaries between the head and the turbo(in the manifold) i shouldn't really lose any boost due to overlap... either way i'm looking for a kit, and the only kit i've been able to find for a 94 with a dohc vtec motor in it is the f-max.. oh, and i have the r-ideal head gasket coming so i can run a little more boost... never heard of rev hard before, anyone have a website i can check it out?

I say the same, rev hard, i got a f-max here, and i regret it, i should of got the rev hard. right now you might say just a little boost, but later along the line, you want more and more, and by the time you get higher on boost, you have to upgrade all the stuff (injectors, pump, etc.) that if you already had the rev hard kit, would of already

The car in my signature is a rev hard equipped 10 second daily driver, with full interior, glass, and sound system.
Ok, I agree that the F-MAX kit doesn't come with the fuel pumps and fuel regulator, which you could purchase on the side for not much more.
However, injecting gasoline before the throttle body is not unlikely water injection for cooling. Injecting gas will serve two purposes:
1) to cool the air
2) to enrich the a/f ratio
first time I heard about water injection, I was like WHAT!! But then, it doesn't sound that bad. The intake Manifold can deal with liquids like MaT3T4 said. So injecting a bit of fuel won't do much either.
Each kit has its short comings I think. F-MAX kit comes with the gasket and the AIC plus the injectors, and fits REALLY WELL. Rev Hard comes with the fuel pump and regulator but no gasket or injector. I also have to admit that the Rev Hard manifold does look prettier. Again, Rev Hard kits doesn't fit as well. Both use T3/T4 hybrid turbos, both boost about the same amount for stage 2, and both are expandable, as long as you've got the cash.
GSRTurboSpec, you complain about not enough boost from the F-MAX kit right? Then you have to go out and buy the fuel pump and regulator plus some new injectors. Let me get this right, I just went onto RevHard's site, and their stage 2 kits doesn't come with injectors anyway. To get more boost out of the RevHard kit, you'd still have to get a thicker head gasket maybe?
Another point is that the AIC has a 3D fuel map (rpm + boost) to better maintain a 14:1 A/F ratio, where as fuel pump and regulator only has a 2D fuel map (boost) to better maintain the same fuel ratio.
My point is, as far as kits out there go, RevHArd and F-MAX are both good in some respects and not so good in others, the best would be to combine the two kits.

Water injection is bad, so is fuel injection before throttle body. It's just something you want to steer clear of if you can.
If cooling was a problem, then all turbo kits would have that. But cooling is not a problem, the only reason for those injectors is extra fuel, and that's a poor exchange for upgrading the stock injectors, like one should.
