i just finished my turbo install on my 99 gsr. i drove it a couple times without any problems, though i didn't rev it very high. one time i drove it, parked for a few minutes, and when i started the car back up the boost stopped building. a few minues previously everything was working just fine. i already checked for loose piping or vaccum hoses. here's my setup:

t3/t4 turbonetics turbo
revhard log manifold
tial 38 mm wg
hks evc (the original one)
vortech bov

what could the problem be?

Maybe the wastegate is stuck partially open.

 

how would i check for that? i already tried taking the top of the wg off, the spring seemed to be seated correctly and everything.

 

if its a open dumptube. put your hand near the opening of hte dumptube and feel if theres any hot air coming out

 

the dp is open. i just started the car and didn't feel any air coming out at idle from the dp. the bov seems to be closed, isn't it supposed to be open at idle? when i stick my hand in it i can't feel any air moving and the valve feels closed.

 

have you checked if the turbo spins freely?

 

yup. i can see it spin when idling. i can also spin it by hand.

 

what're the chances of the ebc taking a ****? i know its pretty old. i'm thinking maybe the valve got stuck or something? its wierd cuz i parked the car for like 10 minutes, and it just stopped going into boost.

Run the WG off spring only.

 

just tried that, still nothing. the boost needle will get close to 0 and just stay there when i rev it up.

 

wait.. are you actually driving the car building boost or are you just revving it in neutral? if you're just revving it in neutral, this doesn't surprise me.. there usually isn't enough load to build boost.

 

yes, i am driving it. i know that it won't build boost in neutral. i've revved it to about 7k rpm when driving without it reaching the 0 mark.

 

make sure u check all vacuum lines and intercooler pipes

edit....can u hear the turbo spool while driving?

Hmmm.. i dont know sounds like you got boost lag.. you must have the new gt50r.. you wont get boost till 9.5k rpm no im jp i dont know.. sounds weird.. im thinking it has to do something with the wastegate or you should check your silicone hose again...

 

Make sure your boost gauge isnt broken. Mine was and i thought i had a boost leak for 2 weeks!

haha so you looked at your gauge... just to see if you were boosting? cant you tell by the way it pulls you back? my gauge reads all wacky but i only looked at it 4 times since i got it..

well if u have already checked everything and u can hear the turbo spool and ur still arent building boost....then it must be something stupid like a vacuum leak or intercooler pipes, so check again.....UNLESS u decided to take it to 7k without any sort of tune and ur blew ur motor
