hi guys i just got done doin my turbo dsm set up install on my prelude with a f22a1 every thing is stock rite now like i didnt do anything else but put in the dsm injectors , dsm manifold,14b turbo,h23 intake manifold, jdm h22a lsd tranny,and front mount intercooler. every thing is on the car except im running open o2 housing rite now and when i go to wide open throttle the turbo boost starts to rise to 15-16 psi on like 5200 rpm! so i stop driving it .. now i was wondering why its boosting soo high so guys let me know what can it be thanks
ps i thought 14b boost at 7-8 psi ? Well heres some pics of my set up pretty much done just needs down pipe made and dyno tune when i get some cash and install my turbo timer also thanks alot for help to: LSD Motorsports - for helping me wtih the intercooler piping layout and shipping me the intercooler hehe at mid night service lol thanks alot man great service Mwinkle for helping me with the boosting problems and my boy roland for helping me with the ecu problems and midniteracer for my ecu socketing service dont laugh its kinda ugly rite now but yea i have bunch of other stuff i will add in a week so ill keep you guys updated ;D Attachment 37160 Attachment 37161 https://img.photobucket.com/albums/v...ofturbof22.jpg Attachment 37162 |

make sure the wastegate isn't seized shut and check the vacuum going to it

The symptoms of a creeping wastegate is hitting 16psi off a 14B. The boost is "creeping" higher than what the wastegate spring is set to. |

Possibly. It should be the first thing you check. |

14b wastegates have a diaphram(SP) that leak when up there in age, I have seen a couple at work.
