The Cometic headgasket will be perfect.
So not everyone is comfortable with modifying the head and block. They'll have their reasons, mistakes can happen and spares hard to get.
The ARP bolts have been proven to work at your power goals.
Thank you Daniel.
Out of topic for a minute.
I wanted to share what happened to my engine in the last few weeks.
Suddenly the noise of the engine changed. It happened when I disconnected the PCV to pop it in the canister. It didn’t work as planned. The engine started to smoke, and I immediately put the pipe back in the inlet. I solved it quickly.
Yeah, the thing I did was installing the BEE R Rev Limiter i bought from Japan. The idea was to try it and use it as a limiter at 6500 rpm. Not to bang at a parking lot.
I also went to the track and did 30 minutes at the limit. The sound of the engine was already different but the perfomance was good. It started to gain turbo lag after.
In my head I thought that testing the rev limiter did actually damage the turbo and so I couldn’t hear its normal turbulence, and the exhaust was sounding more like an aspirated engine. Wierd.
The engine runs well, and there is no obstruction in the intake.
End of the story, I swapped the turbo with an identical, fresh machined hybrid CT9. It didn’t change that much and actually the sound is the same. Ineill send out the turbo to be checked but it looks fine. What happened?
