boost problem

[s13 drifter]

hows things.right i have a boost issue with an sr20det.it has full hks exhaust,z32,hks cone filter,arc intercooler and arc bov.it was boosting .7 before the intercooler was installed now .45.will a simple map sort this or is it something more serious?i no it would be easier tell if ye could see the car runnin but im just lookin for opinions on this one.there is a very small blow out from one of the gaskets on the de-cat, u cant even hear the blow out on it.any help or ideas greatly appreciated

was it like that once intercooler was fitted?? any loose pipes etc?

[s13 drifter]

yup only sense the intercooler was fitted.i checked all the pipes n there grand.i wonder if it a boost leak swomewhere else?

[mcdae86]

same thing happened me abput 3 months ago and still not sorted!! :) i put a walbro pump into it and it solved it good bit, i know its unrelated but dunno why it helped :confused: i went over all the pipes about 10 times but one pipe i didnt spot was leaking so worth having good check over them..

You prob somehow bypassed your boost solenoid...

[s13 drifter]

i dunno lad could be anythin its wreakin my head.the intercooler was fitted couple of days before i bought it.ill have a better look again tomorrow

just another quick question.when the standard intercooler is removed and the new front mount is installed, should there be any pipes left that were on the standard one that need to be blocked off?ive googled it to try find pics of how it should be but nothing is really that clear.thanks for any help i really appreciate it :)

there defo a vacum pipe prob there most likely down at your air intake pipe passenger side turbo area

make sure you have all good clips the proper ones,not just jubilee clips, seen the same problem and swoped all the clips for these type

and wallah...

Is it boost cutting really bad when you floor it? or just a constant lag?

There Mikolor clamps... A worthy investent... But buy them from an agricultural supplier / hardware... That way they are 1/10th the price than certain tuners (pointing no fingers) - a worth while investment... Dont think that would be the issue... Boost leaks are easy to identify if you've got a boost gauge..?! Or test it for leaks if you have a compressor, pressure gauge, 2 hose blanks and some air line fittings..See youtube - boost leak testing

its boostin grand but will only go as far as .45 on the guage.ill try swappin those clamps on sat when iv more light its too feckin dark to do anythin by the time i get back from work.nice one lads

are all your intercooler pipes got good tight clips, boost leaking might cause this aswell
