Yes another "please confirm my worst fears have come true" thread
So I hit a boost spike as the second turbo came on (14psi) in about -5 degrees celsius... im thinking the huge amount of ice cold pressurized air was too much for my fuel system to keep up with....
Im thinking I blew a corner seal... the car will start right up and will rev OK... but idle is really fucky... and the vaccume meter is bouncing up to 14 or so then back down to 16 in relation to engine rotation...
Needless to say Im pretty upset right now...
:S

looks like you have JDM type R. I bought 95 JDM type R as well. how many miles did your engine have when you bought it and how many did have you put on it since?

7 is a little low IMO... 10 is good... not too hard on anything. BTW the boost controller won't prevent boost spiking on stock twins from what I've read.
Just go through the revs and watch the boost gauge... if its not doing anything then I wouldnt worry. mine would spike when the second turbo came on almost every time that is what has caused this **I think**
from what Ive heard about JDM FDs Id be more concerned about coolant seal failure... A couple Ive heard of have blown coolant seals, and the previous owners just traded them in instead of getting them repaired. and thus the FDs would end up in the export yard.

I understood that was only a concern if running a very low-restriction exhaust. Ohh and I've never seen boost creep, just spike.

Good luck on the compression test.

A boost spike at 14psi in -5 celsius with stock fuel could blow a brand new angine from what I've read

Coolant seals in the engine are damadged mostly by overheating no matter its rotary or piston.
