Hey guys i need some major help. I bought a 1994 integra shell. Then i bought a LS motor out of a DA with a gsr tranny to drop in it. The motor is in and running, however it sounds like a subie at idle and once it hits 3500 on the tach sounds like it hits 2 step or a rev limiter..ive changed the plugs,wires,dizzy and injectors. What else could be going on??

 

are you sure your timing belt is on correct and that you plug wire are in the correct places? sounds like it could be a missfire. any cel lights?

 

The firing order is correct and its in time. the car is obd1 but the motor is obd0. I know im going to get slammed, but i went the cheap route and just wired in the injectors and dizzy. Someone said it could be my tps, or my ecu. i have an obd 1 p75 ecu in right now. And I also have no o2 sensor..any ideas?

 

you got a newer 94 shell with a DA LS. that just seems like a waste of money and time. here in CA you couldnt legally swap an older engine in a newer car. and B18A1 puts 130hp vs the B18B1 puts out 140Hp.

 

your post is a waste of time.

Now, back to helping this guy out. Usually if you dont have an o2 sensor your car will run like crap (especially on obd1). There should be one on the header?

Also, other than that, did you see the a1 running properly?

 

You said at 3,500 it sounds like you are hitting the rev limiter? Does the car allow you to go past the 3,500 rpm? If it doesn't then you are in limp mode. Did you wire your dizzy right? I did this in my crx with an obd2 b16 and I messed up my wiring on my dizzy. I was in limp mode.

Check for check engine lights, and if you are in limp mode I'm sure their are plenty of past threads here to guide you through what to do.

 

i went and grabbed a buddies obd1 dizzy and plugged it right into the harness..and its still runs the same..since i wired it up the first time and may have had it wrong..would the ecu still think it was in limp mode??

 

No O2 sensor = limp mode, right?
