Hello I have been looking around this site for information about various simple improvments I can make to my Hyundai 97 accent, and I am quiet the novice. I have installed Platinum Plugs, Taken off the tong tubing from my air filter unit and I have been looking into other improvments. I hae heard that a special fuel pump might help. I was wondering, would an Elantra fuel pump work on the Accent, and if it would would that increase the fuel output? Possibly one from the Sonata? Also on a Bored Throtle Body, would one from an Elantra or Sonata work on the accent, and if so would it have a larger bore diameter for better air flow? I am wondering about those because it would be simple for me to get these parts from the Junk Yards in town. I am also considering NOS eventually. The Zex Nos sounds full proof, which is what I could use, although if it activates when throtle is at full wouldnt I get the NOS kicks each time I hit 5800 rpm? if so wouldnt that be bad with say 4 NOS boosts?
I hope someone can help, and that I dont sound too foolish (the last auto that I worked on was a 65 ford P/U. alot dif)

Hey...leucoandro.

Welcome to HyundaiPerformance.com.
Sounds like you're more than a novice. <img src=/images/forums/snitz/smile.gif width=15 height=15 border=0>
Well... most of the stuff you've written about can be done if I'm not mistaken.
I'm sure more experienced members will jump in and give you some sound advice or some detailed instructions. <img src=/images/forums/snitz/approve.gif width=15 height=15 border=0>

Most people would suggest doing the basic I/H/E. (Intake, Headers, Exhaust) Like a do it yourself Cold Air Intake or looking into company's like KORE or Sharkracing.

Some people do have BBTB and I'm sure one or more members have an Elantra TB if I remember clearly.
hehe and of course NOS... who hasn't considered it? Safe and moderate use with a lower shot should be fine without much modifications to your engine.

Yup... hitting the Junk Yards can be cheaper so that's a good idea.

So hopefully some other members will give you a hand and help out a fellow car person.

Again... Welcome to the fourms and hope you find what you're looking for. <img src=/images/forums/snitz/smile.gif width=15 height=15 border=0>

Oh yeah... forgot to mention, If you did want to do something a little more ambitious, you could do an engine swap with either the 1.8L Beta or 2.0L beta from a tiburon or an elantra.

HyundaiPerfomance.com will soon be coming out with a kit for the swap... don't know too much info on it yet, but sounds pretty good.
I'm sure there are a few people waiting for this like some of the admins. <img src=/images/forums/snitz/wink.gif width=15 height=15 border=0>

Thanks for the imput, although I am trying to do small mods at the moment so I can put the original parts back on if I have any problems (so hyundai will fix it if it breaks)I have been thinking about installing a 2.25" with a tuner muffler that I saw, if that wont void my warrenty, although I am sure installing headers would have an impact on the warrenty. I figured if I could put the Elantra or Sonata fuel pump on my car it should increase the fuel output (not sure if it would though) and I also figured that the throttle body from either of those would be larger and hense inable a higher air flow (not sure if they are larger though). Also if and when I finally deside to put nitrous on my car I thought that I would go with the 30, although I have read on the post I can go up to 50, I thought that I would stay in the safe zone. Although what I am thinking about doing to my car once my warrenty runs out is throwwing a Tiburon motor in, getting turbo, and a 60 nitro.
I should be able to get a Tiburon Engine from the junk yards around here for about 2-2.5K and then turbo for about 500-1,000. then Nitro for a little more, add in the miner mods I would have to make to the engine and it would still be cheeper than getting a new car.
What do ya'll think?
any idea on how easy the fuel pump, and throttle body changes to that from a sonata or elantra would be and if it would help?
thanks

Dude, welcome to HP, enjoy your stay. You can get the Tibby motor/trans for around $1000, look around on this site, i think sharkracing has them. A Turbo on the other hand will cost ALOT more, for the parts and the install. Then you have to tune your fuel curve, and all the other little joys of forced induction. As for keeping your warrenty, you can plumb nitrous into your intake pipe and just take all of it off as a single unit when you eventually get greedy with the NOS and break something.<img src=/images/forums/snitz/oogle.gif width=15 height=15 border=0>

Turns out things are as complicated and as intailed as I had feared, although from what I have read I gather that the cheepest things I can do for HP would be in addition to my Homemade CAI, put in a higher PSI fuel pump, Larger Diameter Throttle Body, go to 2.25 exaust, and NOS, Looks like the Zex at 55 boost would be good. I was looking on E-bay and saw kits, saw one zex, used, all parts for HONDA CIVIC, INTEGRA for $102.50, is it a universal system and would that work on my accent?
I know I should post that in the NOS section.
Also I have platinum plugs in it right now, if I went to nos I would go the 2 cooler. with those miner improvments what could I run with, could I keep up with say a stock Mercury couger 6 cyl sports pack, or a Ford Mustang 6 cyl? what would be in my class that would be stock?

KORE carries the motors for $1000.

A very basic turbo setup should run about $2500.

Unless you change your fuel pressure regulator, changing the pump will do little or nothing. The stock Pump will push more than you need for the mods you have described. An adjustable regulator would be a better option, or there is a ghetto way to boost pressure by slightly crushing your stock regulator - but unless you have done it before, I don't recommend it.

HySpeed has been developing SOHC Accent cams which should work very nicely for you. I am getting my car dynoed on Jan 28, and if all goes well you should be able to purchase them shortly after that.

I personally would not go greater than 2" for the exhaust. HVE and others that have tried ended up losing a lot at low rpm, and only gaining a mild increase at high rpm with anything larger than 2".

Honestly, if you are thinking about a Beta swap, do as little as possible to your 1.5l as you can. Pre-'98 Accents are slightly different than the '98-99, and require more work for the Beta swap. Putting an exhaust that will work best for the 1.5l, and then dropping in a Beta would be a waste of money. Put more money into brakes, wheels, tires, and suspension, and save for the motor transplant.

As for your dealer - very few will touch a Hybrid. At least not without raping you financially! Get to know a local small Hyundai/Mitsubishi shop (preferably in that order). If they can do the swap, they will be able to take care of you after that. Hyundai dealers are fine for parts and service while the car is under warranty. Once you start messing around with the car, few will take the time to fart around with a modded car.

Hope this is helpful, JP.<img src=/images/forums/snitz/cool.gif width=15 height=15 border=0>

OK so without the Regulator the pump does little. Would I be able to get the Fuel Pressure regulator and pump from an elantra sonata, or Tiburon to just bolt on my accent, or is there more involved. I havnt seen anything about using the regulor or pup for accents from any other hyundai cars, if I install a regulator and pump from one of the larger hyundai's would I notice much improvemnt. I also read and saw where someone took the throttle body from a tiburon and put it on his accent, but he said it bucked, and didnt say if he had to customize anything
What I have on my car now is a homemade CAI, platinum plugs, and elantra 185/60 R14 Cooper Cobra GT's got all 4 tires for 217
I was just wanting to do the above parts for now since if I have engine problems I can bolt the old parts in easily
Thanks

This isn't my own experience, but someone said the pumps for the Accent and the Tib are identical. A pump from an Eclipse would be a better choice since the DSM guys all upgrade those when they go for increasing boost pressures.

A regulator from another car might be a possibility. But remember, fuel pressure alone might not be the answer. Sometimes bigger injectors will still use the same pressure, so you may find the regulator from the other motors are the same. I have the Accent pressure for the '98 being 43.5 psi, and Webtech lists the '99 Tib regulator at 43.3 psi. So you would need to look elsewhere for a boost in pressure. From what I know, cranking the pressure to the injectors to try to force more fuel through them can mess up the spray pattern causing the injector not to atomize the fuel properly. Bigger injectors , or re-working the computer to open the injector longer (or better yet both) might be of help. Someone on HyundaiTuner.com mentioned having an adjustable regulator designed for a Buick Regal Grand National which worked on their car.

As for the Tib throttle body, some guys take the backyard approach (Dremel), and make it fit. Others have gone to machine shops to have it done to perfection. Either way it does work, and one is going on mine as soon as the baseline dyno runs are done for the HySpeed camshaft on my stock head. After that, the fun begins.

Well you have to come to a crossroads, my friend. All those bolt on mods really won't get your hyundai moving anywhere fast. Lets say this.
Stock 1.5l is rated around 95hp<img src=/images/forums/snitz/cry.gif width=16 height=16 border=0>
CAI +5
exhaust +5
header +5
bbtb +3
port matched Intake manifold +2-3

116 hp at the crank, nothing to write home to moms about. All those mods would cost you over $1000, without any real performance gain. With the money you would have spent, you can have a 130hp 2.0L beta, but you would still have to pay for install.
2.0l Beta 1000-1200
install 500-600

OR you could spend 500-600 beans on a nitrous kit, with about another 300-400 for install and have 145hp with the flip of a switch<img src=/images/forums/snitz/thumbup.gif width=25 height=18 border=0>
