Hey people, im thinking of getting some more juice out of my 4g63 yet i have a couple of questions.

1)Im gonna get the hks 272s, and cam gears; now what brand of gears should i get? hks, fidanza?

2)What should i set the gears to? ive heard -4,-1 works great because it fixes the idle and crazy top end pull. Any other settings?

3) im also going to reflash my ecu, any recommendations about whom should i send it to? dynoflash, turbotrix, vishnu? and how does this proccess work? Will this fix the idle? And wil the basic flash be enough for the mods im getting? Or i have to get some sort of custom flash?

4)Do i need bigger injectors? if yes, what size should i get? and yes im planning on upgrading the turbo after i max out the stock one.

5) I will also get a walbro fuel pump, yet ive heard this fuel pump makes weird noises? why and will the flash fix this issue?

6)I will also get arp headstuds. Now how does this work? correct me if im wrong but installing cames raises your boost at higher rpms right? so what can i boost with cams? Im currently at 20psi using a hallman mbc.

7) thinking of an intake and to also take advantage of the reflash, i will get the hks rs intake, is it true i could achieve 15whp with this intake and a tune?

Do u think i will achieve 350+whp with these mods plus my ams full exhaust on 93oct? ....i really appreciate your time people thanks

 

1) wouldn't matter, i'd go fidanza for the price. It's all the same
2) -3,-3 for now until you get on the dyno and try out different combinations.
3)No comment
4)The injectors are already maxed out on the stock turbo. I'd go 680's. Those are plenty.
5)Fuel pump makes noise because it's working hard. No flash will ever fix it.
6)I don't recommend arp headstuds without fully building the engine. Cams don't raise your boost by themselves. You can boost about 21 psi on 93 octane with cams.
7) Leave the stock intake box and get a k&n drop in. That way you get better flow yet it won't mess up the mass airflow sensor and cause problems.
I doubt you'll net 350+ without racegas.

 

ive seen a lot of people here reaching 350+ whp with the mods ive mentioned.

 

You haven't specified what year Evo you have. Anyway I think that you are like me a few months ago(like a loose chiken without the head,please no ofense), I was looking for upgrades but did not know what, where, who, how much, etc.etc,

I was told that you don't really need the cams gears unless you like to adjust them and you knoiw how to do them(It looks like you wouldn't know, please no ofense)

As per the Cams, you can get them cheaper from Buddy club, HKS or GSC cams wich are identical to the HKS but don't have the polished lobe surface(HKS does).
The 264/264 will give you a more lower/mid range while the 272/272 will give you more top end. You can get a combo of 264/272 or 272/264 or whatever but the 264/264 work great on my car.

The answer to your question, I am boosting with my 264/264 cams about 1.7 bars peak(the gauge goes well pass the 1.5 bars), no detonation at all and stays steady to 1.4bars all the way to almost 8000rpm.

The HKS filter is nice, unfortunately if you live in the desert ( Like I do) it is strongly NOT recommended because it is too pourous other than that the actual piping of the air filter is huge and it will make a very loud noise when you floor the gas pedal.

Again, the Injectors are not really needed as long as you get a good tunning and your configuration is set up right. I don't have neither injectors or fuel pump on my 05 MR.

You might not need a fuel pump after all, I don't have one and my car is running great. Unless you go with bigger turbo I don't think you need one.

You mentioned about the apr headstuds. I don't have them and my car is tune to 8000rpm with Al(Dynoflash), he did a custom road tunning.

I think you are a person like me, you want to max out the stock turbo capabilities before jumping to a bigger turbo, intercooler etc.

I am also getting the upper and lower IC pipes (upper from Buschur, lower from Fighters-garage). I have a set of headers and I am waiting for the Works O2 housing.

Please read my mods and accomplishment and make your own mind. Like I said, half of the stuff you don't need for now(intrecooler, fuel pump, injectors,cam gears, studs)

Good luck!!

I just ordered Lower and upper pipes and I have headers on hand (not installed

 

YOU WROTE:

4)Do i need bigger injectors? if yes, what size should i get? and yes im planning on upgrading the turbo after i max out the stock one.

--------------------------------------------------------------------------------------------------------
Another comment that I have for you is save the money from(intercooler, cam gears,fuel pump,injectors and headstuds) and put it on:

Works o2 housing(it will be the only truly 3")
intercooler piping(lower and upper) check Buschur and **************************
headers check Logicperformance.com

The other altenative route(the one I am taking next) is get yourself a good alcohol/methanol/water injection kit and have it tune.

As per the tuners, yeah, definately go with someone that knows the ****:

AMS
Turbotrix
Dynoflash (that is what i got)
Buschur
Pruven performance
Works
Vishnu
Ultimate -racing
etc, etc sorry if I forgot any well known tuner!

 

thanks for ur help man but i think i will get the cam gears to extract more power out of the camshafts and also so id kill two birds in one shot while im doing the cams and the headstuds just as a prevention. Im not too good at remembering the bar coversion yet whats 1.4 or 1.5 bar in psi? . Then about the turbo manifold, i dont know about that since i will get the ams turbo kit eventually and it will come with one so itd be a waste of money. Same for the o2 housing. The i/c is a good idea then again i wanna do what i said first and then get the ams FMIC along with their lower i/c pipe since its more important than the upper one because its tinier ( 1.5" at one point). I live in miami so i wont have to worry about any sand going through my intake, so i think i will get the hks rs kit just to take advantage of the flash. I like killing two birds in one shot u know what i mean? oh yea and i have a 04. Well thanks for ur help man

 

Yes, I understand you. Everything has a logical start, like you said, why to buy a set of headers when a new turbokit comes with it?etc, etc.

Once you make your mind on upgrading the turbo, then there is no way back, you have to have the fuel pump, you have to do the injectors, you have to get the intercooler, you have to tune it, you have to get a BOV a MBC a boost gauge and the list goes on and on.

I was trying to illustrate you my performance mods and my track times just to give you an idea of what the EVO is capable of. I had the perception that you said that You want to maximize the stock turbo before getting the upgrade.

To me the stock turbo and intercooler have a lot to say as far is performance.
The alcohol injection,the headers, the upper IC pipes, the lower IC pipes and the O2 Housing should give me an additional 30-40whp (I think).

1 boost bar is 14psi or 14.7psi(I think), the 1.5 bars is 22.05psi for sure(I know that one)

my .50c

 

Yea i guess so. Thanks for you comments but i'd like to hear some more oppinions from different people.

 

anybody?

 

If your flash is mail-in I would talk to the flash vendors, tell them the types of upgrades you want to do and find out which combinations, if not vendors themselves, they've tuned for! That way your flash will be most accurate for your parts ... make sense?

 

1. HKS gears.. which size is preference but tried and true is worth the couple extra dollars.
2. Dont Know
3. If you have a S-AFC II you should be able to fix any idle issues you have atm. As far as I know since you already have S-AFC a reflash would help you get rid of the rev limiter but if you want good tuning you should be able to use your s-afc or get settings from a vendor like Kazz said. <--- buschur..
4. Injectors and pump are a up for discussion. Some pps say if you get cams, some say if you upgrade to a bigger turbo. For safer and better tuning it would help to get 660's and a walbro. Again this would be up to you or when you make the call for #3 ask em. But seach for good prices on the net first.
5. Answered above.. except yes it will whine (255lph) and no a flash wont change that.
6. For what $100? or so... arp headstuds are worth it. Maybe not for your level of modding but why the hell not. While your out spending money on cheapy stuff get a set of NGK spark plug wires and NGK bpr7's.. will total for under $100
7. Dont get the HKS intake. Goto roadraceengineering.com and buy their K&N Intake with the AEM pipe for $205. Nothing better for the money... my opinion.

As far as whp numbers... Ive never been good at that. With these mods and your previously stated mods + GOOD tuning + a real launch you should be running mid 12's like 'fromWRXtoEVO'; but take into consideratio he is running 91 octane mostly.

You have got to get taht 5k rev limiter crap disconnected or removed if you know how to launch or you'll just bog. The most important part of your mods will be the tuning. I dont know where you live but if your near mid ohio or jersey buschur or turbotrix could give you a kickass tune. And llastly when buying parts... price shop. Alot of stuff.. injectors, pump, wires, cams, etc are sold everywhere. Sometimes Buschur sells em for cheaper.. sometimes roadraceengineering.com does.. then slowboyracing.com has a sale and is CHEAP. <shrug> It pays to shop around before you get a biased opinion from one shop who just wants to sell you their stuff. I will say though... dave buschur's posts on here to me reflect that he wont screw ya... so I would be very inclined to look at giving them your business.

 

im running on 93oct and pretty decent launcher considering i dont do it every day. think low 12s dont u think?
