Default Just replaced intake manifold gaskets on 02 WRX

Reason why they were replaced:
Passenger side intake manifold gasket blew soon after installing TXS TMIC most likely due to ~3psi more pressure drop over JDM STI core. Car could not reach target boost of 19psi (protuned) and finally after performing DIY leak test I realized that it was leaking through intake manifold gasket.

New gaskets:
Ordered a pair of Grimmspeed intake manifold gaskets for $9.99 plus shipping, which is a great deal.

Installation

Unfortunately, my camera battery went missing, so I wasn't able to take any pictures.

Took a little over 4 hours including having a dinner.

In my opinion, the hardest part was scraping old gasket off without scratching the surface, which is why it took an hour to completely scrape off all. There were hardened gasket material that had to be removed using a sharp blade.

I did not drain the coolant nor remove power steering pump. Just moved the power steering hard line instead. My co-worker (DSM guy) recommended that gasket sealant be used, but I opted not to based on GrimmSpeed's recommendation.

Haven't had a chance to test drive it, but will see what happens tomorrow morning.

So you pressure tested by hooking up at the trottle body?

I'm happy for you and wish you all the best, but an engine stops in a position where at least one set of exhaust valves are open. How did you build pressure in the head, to see it was leaking?
Did you spray soap and it bubbled? If so, you probably got lucky and it stopped just so that the exhaust valves were closed on the runner that leaked..
