b18b in ej2 reduced redline need help asap
alright so i have a b18b1 in my ej2 and when i first put my swap in last year it revved to 7200
but now it only revs to 5500 once in a blue moon it will rev to 6500
ive tried looking online but some people say maybe fuel filter,tps,map, or speed sensor
i know someone ran into this problem and hopefully someone can help me out
i changed plugs and wires about 10k ago and my friend gave me another dizzy with no cap so i had to swap caps but his was completly shot so i went back to my dizzy but the cap and rotor seemed good and i pulled one plug at a time from the dizzy while running and it gets excellent spark
oh and its a stock motor with stock header, stock cat and stock integra pipping to a vibrant muffler on stock ls computer, and i only run 89 in my car and only from sunoco if it helps any
also when it hits 5500 it acts just like a redline like it use to at 7200

Check for fouled spark plugs. By chance, what type of spark plug wires are you running? If its MSD Ignition wires, trash them and go back to Genuine Honda or NGKs.

Have you checked the timing, given it a tune up? Have you done anything!?
Also, when swapping the dizzys did you mark the ears to insure it went back on in the right spot?

Re: b18b in ej2 reduced redline need help asap
like stated above i did a tuneup and timing belt waterpump 10k ago and it runs mint besides the reduced redline but talked with a few local people and they say it could be my map or speed sensor based off similiar issues so im gonna try them tomorrow by cleaning both and making sure wires are good

Re: b18b in ej2 reduced redline need help asap
its a p75 and was fine when i did the swap last year but im gonna try my p06 cause i used it once before and it revved to 6500
another update:: i checked the plugs today and all were good besides cylinder 3 the spark plug gasket leaked so there was oil on the spark plug, so i took off the valve cover and resealed the spark plugs and calve cover itself but all the plugs were still within gap spec and werent fouled out or anything

I have ran into this issue before. But mine wasn't revving over like 2k. Changed everything you can think of and it ended up being the piece on the end of the fuel rail with the plastic cover on it. worked perfect after that..
