I have a drag turbo kit on my 94 GSR tuned with hondata...and its not pulling when I make full boost. I just hear the turbo spooling but it runs like an N/A car...I know i dont have a boost leak because the boost controller is tapped directly into the intake manifold, and its reading a steady 7 psi every time. I also am not blowing any black or white smoke, or burning oil....Ive checked the oil level periodically and its been the same. I also checked to see if the timing was correct....everything seems to be tuned right. Could compression be a reason? Im going to do a compression test next, but if I had bad compression wouldnt I be burning oil? Or wouldnt my motor feel weak when it was N/A? Because right before I put the kit on my car was running very strong. The only doubt I have is that the motor has 190,000 miles on it.....but then again i bought it with 153k from an old women who put mostly highway miles with it....so i think it should be in good shape....what do u guys think the problem could be? anyone ever hear of this happening?

 

What is your boost guage reading? Is it actually going up to 7psi?. If not, could mean that you have a pipe disconnected somewhere causing the turbo to no longer pressurize. Don't just look at the boost controller, look at the guage.

 

im sry i mean he boost guage is reading 7psi steadily....which is tapped into the intake manifold...so theres no leaks

 

are your butterflies opening? Josh (westcoaststyle) had to advance his timing just a touch, maybe you might need to. Is there any gas smell when you get out of the car. Maybe your intake valves are staying open a hair too long. maybe your manifold is leaking. Have you tried replacing the gasket there? If not the it cant hurt anything but the wallet by like 15 bucks. Are all vacuums in place? Is the boost guage hooked up correctly?
