Honda Car Forum

I currently have a 00 civic with a k20a motor and was boosted at 15 psi. The car is being rebuilt from the ground up and when the car was finally finished it ran perfect. After about 2 weeks of testing and tuning the car some odd reason the boost gauge is all of a sudden saying its only at 5 psi? We dyno the car a few times to make sure its only the gauges but it wasnt and we cant seem to get it back up to 15 psi. Any ideas why the car dont wanna go to 15 psi? If someone can help me soon it be a big help because we want to get the car finished before the drag strip opens up.

well theres your problem. the problem is that its a HONDA! those little junk wasnt ment for turbo. think about it why didnt civics come with turbo? meaning their not ment for turbo? DUH! and i say you spent about 20,000 on that car already and only runs 16 in a qtr mile. so theres your problem

Double check all cold pipes for leaks. Make sure the wastegate isn't opening early or stuck.

what kind of turbo do u have? t3/ t4 often do that.. but hey good luck dont exactly know what to say but .. the ****IN ASS HOLE JON B is jus peice of shit.. i am pretty sure your proud of that turbo.. i love the squeeling and ****in blow off valve is just amazing.. good luck bro..

Leave some more info:What RPM was it previously reaching full boost, and what RPM is it reaching full five now? Is it reaching 5 psi where it was before, or is it reaching 5 psi where it used to reach 15?If it is reaching 5 psi at the same rpm as before, but then just topping at 5psi, I would check the wastegate and lines around it, that would sound almost exactly like a BOV issue. If it is reaching max boost of 5psi where it used to reach 15psi, then it sounds like an issue with the turbo. I'd check all the piping, intercooler, oil lines, etc etc.

BTW does it loose boost when you shift maybe a boost leak I need alot more info. And btw honda did make turbo cars for there racing serious Honda musem in Japan.

it should be you waste gate but check your check valves on you VPC. if they are clogged or disconnected it might not boost

its probably a compression problem, check the piston seals, and dont listen to jon b... hes obviously retarded and probably drives an american peice of shit
