cant go beyond 4k
well. boosted. got a new apexi BOV and it was great. however, i dont seem to be able to pull over 4k rpm. its like i will have a violent jerk when i reach the 4000 rpm rev and i dont dare to cross the line. what could go wrong? heard something abt the fuel lines or rails needs upgrading. true? anybody?
p.s: boosters, have you guys done any return fuel system? change fuel rails? whats the fuel system that you guys are running?

Unless you run insane boost, you dont need to upgrade fuel lines or fuel pump.

i am betting its the fuel, he doesnt have enough fuel, its running in safe mode, or its creating its own rev limit, or it feels like it, the whole car starts bouncing. sometimes you get backfire??? more fuel then, rsx injectors and emanage, or apexi s-afc

Rep Power: 0 not enough fuel? at idling its damn rich. black smoke and soot. and i can say its untuned for now. just running rich to play safe
so i need a return fuel system eh? im just running on management that does only fueling. no ignition no nothing.im gonna hook up emanage with injector,ignition and boost. its gonna help? just to ask does the y8 mani support returnless fuel system? im gonna bolt it on.
o yeah. ive got a cel. and when i recycled my bat..the cel went off. but it came back on afterwards while travelling on highway. ive not cat. so i cant tell...
desperate.

Rep Power: 262 This goes to show how investing some money on the front end of the project WILL cost less in the long run. I personally would never boost my car without doing some serious thought first, and then adding the necessary modifications to go with it. So many people are like, oh yeah i'll turbo it, and forget that they need upgraded fuel systems, engine management, tuning....to do it right it costs money, but to me having a car with a blown up engine and having to flintstone around town costs more...thats my .02...not to down you dude, but if you fail to plan, then you plan to fail....
yeah def. gonna need engine management! im sure your spraying way too much fuel,prob stock plugs,stock gap? map seeing boost. got alot work to do. park it till then.Return fuel system is not a must. it's great if your going for big numbers but the car will run fine up to 12psi on the returnless. oh and get that cel scanned, resetting it won;t fix anything.

As someone said before look into MAP sensor issues.
I've had same thing, cant rev past 4k rpm and CEL. I upgrated to "Missing Link" and not it runs smooth as stock.

Rep Power: 0 this is what i did to make it go away, make sure you are using premium gas, 91 oct. or higher, if engine light on, clear it, unplug ur map sensor, drive it , let it idle for 40sec and plug the map sensor in. i did that and its good but not the best, still waiting fuel upgrade.... hope that helps.

Rep Power: 285 Here is my fuel system...
I planned this very in-depthly. I conversed with some of the best tuners in california to come up with a method of controlling these, and how to get the most power and the best drivability.
I have been designing this turbo kit for over a year now. I did not plan on it taking this long. But it took 9 months to get my custom parts (pistons, rod bearings). But it was a good thing. Even though i know what i am doing, i did even more research. I talked with TONS of people, exchanged insane amounts of info and ideas with eachother. And now i think i have one of the best designed fuel systems possible. The only thing i think i could do to improve upon it is add an AEM instead of an emanage. And i will do just that when i get a bit more money. I would wait, but i have obligations to get the car running by April 8th. I have to race at IDRC nationals.

Rep Power: 0 mayday mayday. ok. ive got myself a boost sensor. tuning on tues an post the results again. ok.this is gonna be damn long and hope you guys understan what im talking abt... probs again.
Basically, ive got myself a y8 mani matched with a b18 LS tb. i just wanna swap it in but it i heard a mechanic telling me the tps for the b18 is in opposite sense;alot of things to do and i need to refab a IAC in order to get it work with the d17. any1 can guide me? im skeptical with the mech i consulted.
IF i just swap the mani in... with our stock tb. whats there to be done to the tps,map sensor, bla bla. or is it a just bolt and drive kinda thing? any1 can share? the tb for y8 is the same as the b18?
lastly, those boosting and running on the y8.. what kinda injectors are you guys running? the mech said i need to change my injectors as they dont fit into the y8... damn stupid.

Rep Power: 285 make sure somebody well experienced with the software tunes the car.
Keep the a/f ratios around 11.2-11.7 while in boost, and keep the timing slightly retarded.
If you go too overboard on pulling the timing, you will lose a lot of power. If you dont pull enough, it wont be reliable for daily use and wouldnt allow for any inconsistencies in the quality of fuel you use.

Rep Power: 0 ok. well. this sucks.
got my stuffs all wired up. got onto the dyno. damn. my boost wouldnt hold. keep surging up to 1.4 bar. something wrong there. and boost comes in real slow...its internally wasgated. so what now?
then. i got him to do a rough tune. and hey. my car stalls when im driving with a/c on and it happends quite often on the highway. idle is abit jumpy and when im accelerating slowly. the car jerks... something like tapping the accel on and off kinda feel. this sucks. end of day paid and job not done. really lost man.

Rep Power: 285 what are you using to control the boost?
1.4 bar of boost is about 19 psi. Entirely too much for your motor.
Did you happen to get a dyno graph you can post up for me? How about an air/fuel graph? If you can post those for me, i can probably help you out a bunch.
