how much can you tinker with the VAFC if the car is breathing through a stock exhaust? I've got an intake on there, but without the other bits I don't think it's flowing too much more than stock. I have heard B18C5s with header/cat/exhaust can make around 5whp after tuning, how much could a near-stock one make without putting the engine in jeopardy?

All I have is an intake and the VAFC, and made well more than 1-2whp... look at the sig.

 

I'm at 172whp/125wtq now. 180 is probably too much to expect, but maybe 176-77, and maybe even 130wtq?

Ahhh, well i was at 169 before the tuning so I picked up ~5-6. Either way don't pay more than $299 for the unit. Otherwise I'd just wait. Have you thought about getting a highflo cat instead?

 

I am waiting on a particular header/exhaust/b-pipe/cat combo. But I'm kind of on a budget, and I thought that the VAFC might be a more useful way to spend my dough, for now at least. Until I get more $$ that is.

 

sorry that this question is off topic but i want to mod my car.........i dont know what i should do, Toda A's or B's?....i want to do something internal, can you guys suggest.....something that will give a big improvement.....thanks

 

Being as nice as possible,

Take your time, create a plan for what you want out of your car and research everything. Then when you have a few ideas, do alot of SEARCHE'S here and on the new and unimproved SHO.

Figure if you want a daily only, track/course, Auto-X or strip car or any combination of the aforementioned. Take a long look at the posts here, the integra forum and the Tech forum, the Hybrid forum may aslo be helpfuml when contemplating hot cams and major engine mods.

Good luck and become one with the Search function, It IS your Friend.

Ross - If you only have an intake, why don't you pick up a JDM 4-1 headr for ~$350. That's guarenteed 3-7 HP... and you can pick up VAFC at a later time.

BlkITR #1825 - holy cow... #1825!?! Is that the highest number ITR on the board?

 

i put down an extra 8 whp with my controller. the key is to turn the vtec up and add about 5-6% more fuel when vtec kicks in.

 

Dom - not trying to be an ***, but you could have made a separate post. this really doesn't add much to my thread. On a more helpful note - here is the philosophy I use when modding my car. If I can't do it myself (or most of it), I don't need to do it. Therefore, my car is mostly stock, and somehow I still manage to have fun. If you go and get a bunch of **** done to your car and run into problems, you'll be relying on some jerkoff at a shop to tell you what's going on...and they almost always lie. Another philosophy - if you have to ask a bunch of strangers on the internet "what should I do to my car?", the answer is "probably nothing" - since you obviously don't have your own opinions about it yet.

Also, take Anton's advice - figure out what you want to do with the car first. Take it to an autocross, or a road course. then, you will realize that you really don't need to do anything else to your car. If your intent is to have a car that looks good and beats your friends' S2K and WRX, then you bought the wrong car...no offense but the Type R just goes to waste if you buy it for street racing. On the track, I have passed Vettes, JRSC-d Type-Rs, and more Porsches than I can count. to me, that's better bragging rights than "I beat my friend's S2K from a roll on the highway". You can IM me if you want, I started out kinda like you...didn't have much racing aspirations, just wanted to go fast and look good doing it. It gets old after a while. peace.

Sean - the header will come when the exhaust is ready. It is in fact a JDM 4-1 and it's sitting on the floor of IPS Racing right now.

Ross, I don't know exactly what the potential of our "Stock" engines are.

I also Dynoed 171.8 and 171.9 with 124 and 122 PF of TQ. this was a good base run that will help me tune next time I get back on the rollers.

After talking to the guys there and actually seeing what Rodney's car started with and was tuned to. I am looking forward to tune with Camgears, Fuel Pressure regulator and a VAFC.

I truely feel that I could extract minimum 5 HP from my car Now. I'll have to see what I eventually am able to get but 5 to 7 HP and at least 1 to 2 PF of TQ is a good possibility.

Is it worth it? I can't answer that for you. I personally think that getting a great header and HF cat first and or the Catback and THEN doing the Tune with just Camgears and FPR is a good plan. The VAFC is not a neccessity but, is a good tool enabling you to control the Air/Fuel ratio, and secondly the Vtec crossover, "which is Not that important for stock setup" but, may provide some power.

Remember that the VAFC while it may have a strong following, is just a PATCH and takes the place of a well tuned or retuned ECU. Something like Hondata's ECU is another idea. But, thinking that any of these will take less tuning time is just silly.

Any way You or I look at it, We are going to need at least the Camgears, FPR. And either the VAFC or a good reprogrammed ECU for more fine tuning.

You know what your graph looks like, and if it's anything like I have on mine, it has a nice steady linear climb to crossover and then a spike and another climb to redline. This is a well tuned Engine/ECU combo Stock, You can't argue with that. But, it is also tuned for mileage and Emissions. After tuning the way we are considering, we will lose some more gas mileage and have slightly poorer emissions.

Sorry for the Rambling but, after my session, I am contemplating all these topics and options as well.

I say just save for your Header/Catback and then Tune tune tune!!!

Good luck Ross,

Anton

PS I do like your MooJen Wingy, IM me with more info about it if you could? Price? and I know it came from Mike right?

 

Anton - the car is leased, so I don't know it I can justify getting a new ECU. But ever since I saw that guy make 190whp with stock cams, I/H/E/cat, lots of VAFC tuning, and FPR, it got me thinking. I'd love to embarass some ******** who spent $3000 on a cam install with my stock "weak" ITR cams. It's sort of like driving skill - it's not a matter of your equipment necessarily, just how you use it.

 

WHOA!......some guy made 190whp with stock cams, I/H/E/cat and lost of VAFC tunning?? Let me in on the tunes.........

 

isnt EP over 200 with stock cams and mugen bolt on's?

 

someone told me 207, but I never actually saw his posts or dyno graphs. It's highly possible...he has basically every Mugen part there is.

 

but i thought the only mugen parts that actually made power were the intake/header/exhaust? well maybe with the ECU and thinner head gasket....**** i dont know what i'm talking about.

I'm with you guys though, i want to take the stock motor as far as I can, that is, when i start trying to get more power. I need to get my license back first though
