I have a 91 da... and im going to be starting the rebuildish on it... but I have a 255 fuel pump in it... i know im not even boosting... but i plan on buying some stuff this week to help it... but my question is... i am going to buy,
1. skunk 2 intake manifold ported.
2. aem fuel rail
3. rc 450 cc injectors
4. aem fuel pressure regulator.
5. throttle body spacer.
6. skunk 2 76mm throttle body.

will i notice a big gain in power at all? or will it not be so great after doing that?

 

What are your actual plans for the build?

The AEM fuel rail won't benefit you at all, and if you're after power gains, you should consider spending your money on items other than an IM, TB and spacer. Why do you need so much fuel?

 

well i mean it would be ideal if running the fuel pump also i need to even the air out also

I'm still not sure what you mean or what you're planning.

Running the upgraded fuel pump along with 450 cc injectors is going to provide far more fuel than you need, unless you are using something to tune with and have a setup (such as forced induction) that requires so much excess fuel.

 

again, what are your goals?

- skunk2 intake manifold will only really benefit you if you're building the motor or going turbo
- AEM fuel rail is pretty much useless bling unless you're running well over 500-600whp
- 450cc injectors are useless unless you're doing an all-motor build or turbo or supercharger, and you also need to get a tune
- AEM fuel pressure regulator again won't really help unless you're doing other stuff and tuning it
- throttle body spacer is something i've only ever seen help with some V6s and V8s...I've actually never seen people use them on our engines...either way, you can better spend your money elsewhere
- same with the throttle body...the 76mm throttle body is HUGE and you really wouldn't see the benefits of it on an otherwise stock engine

You really need to figure out what you want your car to be able to do, then figure out what you'll need to get to achieve that goal. You can't just piece everything together bit by bit, installing parts haphazardly until you eventually get the whole thing going.

Keep in mind that engines run as a system...upgrading one small piece or another small piece won't give you a good result without also doing other supporting modifications. For example, installing just a header or just a high-flow cat will give you virtually no gains, while doing an intake as well as a full exhaust would help a lot more.

Figure out your goals, think of everything as a system where each piece works WITH other pieces, then plan out everything you'll need.

You're more than welcome to ask questions and ask for advice, but you also need to know what you want first.

 

judging from your list and geussing ur not even getting it street tuned i see that your actually losing power....especially with such a big TB, theres no reason for it...... your actually dropping velocity because its so big which slows down your intake air flow

 

Rather than spend money on a bunch of bolt ons on what i'm assuming is a stock B18A in a 91 Integra, i would concentrate my funds on the internals of the motor first in order to take advantage of the parts you mentioned.

If you're looking to go all motor, i'd go with higher compression pistons (11-12:1 ratio), strengthened rods, bearings, a ported/polished head, better valvetrain, etc. You might also look into the possibility of using a VTEC equipped head from a GSR or Type-R Integra, or a Civic Si (B18C1, B18C5, or B16A motor). Only after that i'd concentrate on extracting more power out of the motor with the bolt on parts.

 

These parts will provide minimal gains without more serious mods. IM and TB are a good idea but 76mm is way to big, go for around 68, even a type R 62 would be a nice upgrade. You could definitely spend your money in better places though.

You will notice a big loss. Wallet and horsepower.

You dont need that much fuel.

You dont need the fuel pump. 255lph is huge. A fuel pump wont make you run richer or leaner if everything else is running correctly. It will add more volume to support the fuel system. It is up to the injectors, ECU, tuning, and fuel pressure regulator to meter the fuel.

450CC injectors on your build would be like watering a tulip using a fire hydrant.

76mm throttle body? It's a 1.8L street motor. cmon.

Bigger is not always better. You need to select the correct parts to make enough power. Also, ask yourself the question "street car or race car" BEFORE you touch anything.

You will need tuning if you get said parts. The tuning will shorten the injector pulse to flow near stock levels. You will be wasting a lot of money on this.


You can gain more power from going LS/VTEC (although, i dont really like that combination), or just buying a DOHC VTEC motor and dropping it in (preferred solution, but more $$).

Your list, with tuning is probably going to be a $1500 expenditure to gain MAYBE 10hp? There are very few parts on that list that will even make any power.

You can send me the $1500, and I will mail you an intake. That way, you still make your 10hp, and your wallet gets lighter for weight reduction. It's a win-win. Let me know if you want my paypal adress.

 

basically everything you listed is useless....if youre not going to turbo it, you wont need injectors any larger than 310cc and even then you'll still have to get it tuned. I dont see any EMS listed...

Figure out what youre going to do and work towards that goal. If your goal is to turbo it, you still wont need the new fuel rail or the FPR...

 

Nothing you listed will do anything, you will lose power, the only thing that would do anything would be the intake manfiold, but the other crap u said would just cancel it out..

You dont need fuel mods unless you have supporting engine mods ( cams, rotating assembly, PP head) etc..

 

yay for lego builds.

Learn some things about air, and you'll see why some of those parts you don't need, considering this is a stock bore, stock compression engine.

dude ur going to loose alota power if u you do that, unless u throw some pretty hefty cams in that car your not going to gain anything from that car, or of course a turbo
