View Full Version : Bogging Issues *Help

07-06-2008, 02:44 PM
I just picked up this 240 yesterday that has a fresh stock sr with the 240sxmotoring swap package. Off the bat i bought the car with a huge mani leak and i'm guessing this guy never wrenched on anything b/c all i had to do was tighten the mani down and it's all good now. Anyways i reset the ecu by pullin the positive off and then i took it for a spin. It has somewhat of a bogging issue, like it's holding back and i have the slightest clue what it can be. It's only getting about 6 psi of boost and the vac is going no less then -6. At part throttle it's fine but if i go w.o.t it is most def is bogging out. This is a totally stock motor with what seems to be a very clean swap so it doesn't look like anything is hacked. It's not throwing a code or anything either. I don't know if this is a common issue with sr's and or if it can be diagnosed via internet. did a runover of everything (ic pipes, sensors ect ect) and all seems to look okay but i might be overlooking something. I am a KA-T guy so i honestly don't know ANYTHING about these motors. I was just looking for a reliable 240 with some simple bolt on to do some drift fun and throw this pile of goodies i have sitting around on. I'm located in south jerz and can meet with anyone who can possibly give me some help. I will pay you with beer:thumbsup

Try adjusting the timming. 12mm and a ext is all you need to adjust the cam angle sensor.

they should have replaced the fuel pump with a higher flowing one see if it was replaced if not go buy one.

Also, I had a similar problem before. I had let my 240 sit around for too long, and almost all my fuel lines had corroded, so I replaced all of those, and car ran perfectly again. You might try that?

tighten all your ic coupling clamps. the guy didnt tq his ex mani enough, who needs solid ic connections when you cant even make boost?
