hi!
My engine swap is done but I have a problem with the fuel injection... The engine is running lean and we juste verify all the sensors, hoses and ecu diagram...
No check engine light...
I have a b20Z 00 with integra RS injection, ecu, tranny, etc...

What could be the problem??? Ecu?? Injectors?? TPS??
I will install for sure a FPR, but where the problem come from???
Every peoples who are running the same engine, did the same thing and everything is ok...

Please help me!! I'm riding in a VW golf 91 for 2 weeks and i want my car back!!!

why are you using the integra ecu and injectors etc?
the injectors probably arent delivering enough fuel

 

install a fuel pressure guage and check to see what the pressure is.....you might need a fuel pump from an integra as well.....

 

Other peoples who are using this setup don't use the Integra fuel pump, the stock fuel pump cans run a H22a so why not a b20z...

I will buy the FPR but it will not solve the cause of the problem...
I still looking for an answer...

It's kinda bizarre...

 

accually the stock civic pump cannot flow well enough for a B18 or a B20.

a freind of mine with a B18C swap into a civic falls right on it's face and practically cuts out at the same time the A/F guage pegs lean and fuel pressure drops.........i dunno maybe his pump was bad but he changed it to an integra pump and it was fine.

anyway get a fuel pressure guage and check out the situation with your fuel pressure

 

Ive heard that the LS ecu with the b20 runs pretty lean especially on the top end.
