ok i know im gonna get alot of **** from this but here goes my noob questions

i recently purchased an 03 lancer when i got stationed at ft lewis,wa

i got an injen cai installed and a 2 3/4 inch exhaust put in my some muffler shop got rid of stock muffler which was huge and still have the cat and resonator on there.i also installed lowering springs and rims and a zex 65 shot nos kit.

my question is this. my service engine soon light is on can it be that my car isnt running right due to the cai and bigger exhaust?

also will bigger injectors make a big difference on my currently na car?

Im currently thinking of purchasing some rods and pistons so i can do some more work on my car i just need some suggestions and some guidance so i dont get blown away by hondas. i want to get at least 7k rpm from my car what do i have to do to achieve this? i know its the crappy 4g94 engine but as with many of us i have a budget and the military isnt exactly a high payin job till i make some rank but i really want to break the 200hp line.what would be some good things to do to beef up my engine and what exactly are the weak points in this engine that need some attention other than rods and pistons.

a little help 4 a poor little lancer soldier is much appreciated and thanks for takin the time to read this noob post.

As for the Check Engine Light ( SES, or CEL)

Disconnect your negative end on your batter for 10 minutes. Re-connect it and it'll reset your ECU and drive your car around for a little while. Drive slowly, don't force the car. If it shuts off, it's okay, since it's in learning mode. This'll take about 15 mins or less and your car will idle nicely. Yes, you'll notice your CEL went away, but remember this is only a quick fix. Now, if comes back on? go to an AUTOZone and have them check it for you and give you the Error Code. Then come back here and tell us what it is, and we can tell you how to take care of it from there!

Edit: I just noticed you're in Germany? Or are you in the states?

 

I'm gonna cut you some slack cause I'm a Veteran myself. What you have done should not normaly cause a CEL unless you have a vaccum leak on the CAI somewhere. What exhaust work was done exactly? From your description it sounds like, other than the CAI, you just had a muffler put on. If you want 200hp you will need only one thing....a turbo. Thats it, NA mods will not get you 200hp on a 4G94. Don't waste your time on higher rated injectors unless you get all the other goodies to go with them, or again, a turbo

 

It is a fact that NOS and the 4g94 don't go well together. Either take it off or use it with the maximum caution.

Apparently the weakest part of the engine are the pistons and rods. If you want to go big change those internals to a nice set of forged internals.
To break that 200hp line you have to go turbo.

As for the 7k RPM I don't know if that is attainable in with the 4g94. Never seen it, but if your willing to spend the money and time on trying than go for it.

 

2 3/4" exhaust is to big for a NA Lancer. 2 1/4" will work better but don't go any bigger than 2 1/2".

 

Be very careful with that NO2. You can search multiple threads on here saying blown block due to NO2. Beef up the lower end, and then you'll be fine with the 65 shot. But for maximum hp, definitely go the turbo route.

 

OK thanks for the help guys. as for reset it was done already and the light still came back on im gonna bring it to the shop here on base and see what comes up from that. as for the nitrous im gonna have to take it off cuz its illegal here in germany and i think the better route right now is the turbo and rods and pistons. the exhaust thing is gonna have to wait a bit cuz my car is still in shipment on its way here to germany because my unit just got restationed to vilseck germany.I just cant wait to get here and put that thing through it's paces on the autobahn. as far as i know for the exhaust is the cat was left on and so was the resonator cuz i didnt want a high pitched buzz bomb. that cel light been on ever since the cai hose that connects it to the intake manifold popped off one day. as for the nitrous i think im gonna junk it because whenever i use it all of my gauge cluster lights go on (battery ,oil, temp,engine) i dont get this but hope i didnt do too much damage to the rings or pistons.there are very few if any performance shops here in germany because they are very strict with vehicle mods and everything else they own so im gonna have to rely on you guys for some help here.

what im gonna do is get pistons and rods and run 15-18lbs of boost.
any opinions on rods and pistons and turbo setup ?
i just need a few numbers thrown at me so i can see kinda where im goin with this and if i need smaller compression ratios for turbo if so what numbers are ideal.i can work on the car all winter cuz i need snow tires just to be legal to drive in germany so im just gonna have it on base and work on it all winter when im not in the field training.

for theguy who asked if i was in the states or germany .
im in germany (vilseck)

Probably just need to disconnect the battery to deal with the CEL. Bigger injectors are useless at the moment, I highly doubt you are even slightly stressing the stock fuel system, plus without tuning extra fuel is just a waste. To rev to 7000 rpm you'd probably need new pistons, not sure about rods and a reflash. Nitrous on our engines is stupid, especially a 65 shot. So far only one person as nitrous and he has like a 40 shot or something pointless.

 

Do not run 15-18 PSI, that is insanely high on our motors. I don't even think Omar or the RRM shop car run that kind of PSI. 6-7 PSI should get you 200+ hp and 12 PSI is good for 250+. A smaller compression ratio will allow you to run higher boost pressure, but it comes at a price. Out of boost your power will be crap, not simply bad, but crap.

 

just thought id get some pix up thanks for the feedback

 

You can run 15-18lbs if you drop compression and add a ****ton of fuel (read: injectors). You've got big plans, and they're all attainable, but you're going to have to square them with cost and practicality. You're talking easily 10g's worth of parts with some labor included for stuff that you probably can't do yourself (unless you're well versed in this sort of thing).

If you only want to break 200whp, that's no problem. Boost it at stock compression, set the wastegate to 6-7psi, and forget it. If you're planning a full rebuild...good luck and godspeed.

 

if all else fails on the check engin light, be a true noob and go to autozone and have them hook ur car up for free and tell u wat the check engin light is. lol. and as for the boost. i agree with the above. the weakest part of our engin is the rods and pistons, but mainly the bolts that hold them together, so make sure if u do get the new rods and pistons that u make sure they come with stronger bolts. the factory bolt wont help much

 

just makin sure i saw what i saw, 15-18lbs of boost? like, for reals? on a 4G94? ............ hmm..... yeah id like to see how long that motor holds up.

 

It's 15-18lbs of boost if you drop the compression.
