first i have no type of engine management or chip at the time -i know thats my 1st mistake
My setup: i have a a6 bottom end with p29 pistons, king bearing,rings,etc. COMPRESSION AVERAGED AT 13:1
p28 ecu,10% better flow oil pump, y8 head gasket,with z6 head and an unknown cam i picked up that i maybe removing for a stock cam soon and d15b7 injector: and 94 integra ls fuel pump: I RUN BP PREMIUM GAS WITH A GALLON OF CAM 2 EVERY FILL UP

I have played with the time at the crank and dizzy until i didnt have anymore spark knock during take of or reving at idle, however the timing is so advaced on dizzy that i have no power through out my powerband(like driving a stock z6 or worse)

When im driving: the car really doesnt have much pull and around 4200rpms with the throttle at 80-100%(vtec range) the car makes a hissing noise what we like to call rattle snake spark knock- im not gonna continue driving it this way the motor has exactly 100miles on it as of last night and the lest sohc i built with the same setup did the exact thing and when i took it apart the compression rings at the top of the piston were seized on the piston from constant spark knock i dont want this to happen again

THE PUPOSE OF THE 5 CYLINDER ACURA LEGEND INJECTORS- im hopping these injectors i picked up out of pick and pull will spray more fuel into the motor to stop the spark knock and give my car more power.
Does any body know the flow of the 5 cylinder legend injector compared to the d15b7 stock dx injectors???: - alot of people said try prelude injector but i havent come across any and do i need to run a risistor box for the legend injectors???(

I NEED HELP ASAP

 

1) I beleive you meant the Acura Vigor.

2) Get a wideband O2 sensor, gauge, datalog, and some way to tune it.

 

the only injectors that are different are the ones that are in h22 motors. all of the rest are the same cc

 

ya ur right it should have been a vigor sorry i didnt check the name but as far as gettin all that to tune the car i know people with all that equip. but they charge alot of money to tune it
and my cousin had the exact setup as mines a few month ago and his didnt spark knock no tuning was done to his car at all i dont understand it
im thinking at the moment its gotta be the injectors

 

are u sure all honda/acura injectors are the same minus prelude, i thought k- series injectors where different and whats the exact flow on the sohc injector anyway i heard somewhere around 270 an prelude was 310 or higher please correct me if im wrong
and with the prelude injectors do i need a risistor box to make them work

 

all the civics and integras should be 240ccs i believe.

 

Civic Si, CRX Si 88-91 Peak and Hold 240cc/min
Civic Si, EX 92-95 Saturated 240cc/min
Civic 96-00 EX(require clips) Saturated 240cc/min
Civic 96-00 CX, DX, LX, HX (require clips) Saturated 185(ish)cc/min
Prelude 92-96 Non-VTEC Peak and Hold 240cc/min
Prelude 92-96 VTEC Peak and Hold 330cc/min
Prelude 97-01 VTEC (require clips) Saturated 280cc/min
Integra LS, RS, GS 90-91 Peak and Hold 240cc/min
Integra LS, GS 92-00 (96+ require clips) Saturated 240cc/min

 

thats no cool now i have to speed more money

 

The vigor should be the same 330cc as the prelude vtec. This is based off of the part numbers of the fuel injectors I just looked up.

 

good so do i need a risistor box to run them
