low power when boosting, help

[goldenchild]

2 days ago the car ran fine and pulled hard at 7psi/-10 vaccum on the boost gauge after i reattached the i.c. piping. Yesterday i removed vaccum lines and ran the car but, it idled very bad, enought to die. I got it to run but their is a lose of power. The hard lines on by the fuel rail are removed, I ran a vaccum line from the back of the manifold the the fpr/boost gauge and I have the brake booster line. The hard lines on the back of the head are there but not connected to vaccum. Today i got the car to idle but their is still a lose of power when boosting, feels the same way it did when the i.c. piping came loose. im going to check compression tomorrow. Please help, thanks

did u cap everything off? and did u leave the IAC line on?

[klattr1]

hope u didnt blow anything.

[goldenchild]

IAC, idle air control, thats located by the fuel rail and manifold right

[AceInhole]

you sure you didn't forget to plug a vacuum line in??

[goldenchild]

yeah im pretty sure , hard lines on back of head, under tb, hard lines by the manifold gone, aiv gone/capped, egr gone, butterfly act gone, pcv still there

[daniel240]

sounds like you forgot to plug something up or you have a big leak somewhere

[goldenchild]

hows does the pressure regulator solenoid for the oem fpr behind the head sound, daniel240. How much vacumm at idle do you guys have I was at -10 first at idle and now its around -20. I read somewhere on the forums that someone else is at -22 at idle. At high rpms before readline, I cant hit redline, the engine doesnt die but it drops rpms until around 3500 in which I can get on her again, is this the fuel cut, or the maf not reading air flow anymore, I dont know

[goldenchild]

where are all the ka24e-t's at that have removed vacuum lines, I know im not the only one

[daniel240]

yea you should be around -20+ at idle, i think im at around -22.

I checked the compression, cyl 1(120), 2(150), 3(140), 4(160)

[trpower7]

That's REALLY bad. I'd say your motor is toast, especially #1.

[Nathan]

Check the compression again, then check it yet again and add a little oil to cyl. number 1. I'm guessing your rings are toast, but you might get lucky and figure out you just made a mistake on doing the compression check the first time.

[klattr1]

i feel bad for ya man. Its happened to me before but with a built motor. There's plenty of stock ka's out there. Get to the dyno next time before you boost it.

[WDRacing]

Man, a 40 point spread in compression is awful. Definitly recheck your numbers...

[goldenchild]

i added oil to the cylinders after testing them and i got , (1) 130,(2),(3), and (4) stayed the same. I tested them again yesterday and got the same, i understand vacuum lines can make your car run like crap, but damn, she doesnt pull, I think the rings are done

[trpower7]

Yeah, your motor is toast. Rebuild time.

[goldenchild]

i got a vacuum line diagram from the fsm and rerouted some lines, the idle is good and no power. I was waiting to see that word (rebuild). I was going to try to pull the motor out this weekend if i have anytime but i really dont think thats going to happen since im getting married, thats for troubleshooting peeps

[goldenchild]

motor is dead, i have another motor with 40,000 miles coming here bye the end of them month
