i have a turbonetics turbo on my car and when i get into the high rpms (around 5)my car starts to back fire and i lose speed and power but when i get on the gas slowly i can get into the high rpms and my car pulls. i cant figure it out. we thought it wasnt getting enough fuel but i just installed 330cc injectors and it still happens. ive tried every thing to get my car more fuel even a b16 ecu, but i recently had my stock exhaust welded back on, could that be the problem?? .. please help!!

two other things my speedometer stoped working and does anyone know how to wire up a resistor pack??

 

Did you upgrade your fuel pump?

 

What are you running for fuel management? You can't just throw larger injectors in your car and expect that to fix your problem, it will just make your car run like ***. You defintely need to get your car tuned. Ditch the stock exhaust too.

 

We need more information about your setup...

It's hard to tell what is going on from your post...

Were you running on stock injectors before you installed the 330s? Like bbka said, we are going to need some more info to help... especially about what kind of fuel management you are using. That's the first step...

And about the resistor pack, wiring is super easy but I'm not sure if that's the problem.

How much boost are you running? I hope not very much

 

im running the 330cc injectors with a Vortech FMU (i believe)and not an upgraded fuel pump. im only running 5psi of boost. it just wont let me go above 5rpms when i step on it. if i need an upgraded fuel pump, what kind should i get.. and im losing the stock exhaust next week hopefully. what else do you need to know about the setup?? thanks

 

you have a missing link or check valves? if im not mistaken you could go past 5k rpm if you didnt hit boost but if it sees boost it would put you in limp mode and limit you to 5k rpm

 

i have the check valves not the missing link

 

whats a missing link and check valve?

 

they are two different options in hiding boost from your map sensor/ecu. honda ecus werent meant for boost so when they see boost they go to limp mode because it thinks something is wrong.

 

ok thanks for letting me know.
