Marty's road to ~450WHP

My build is finished!

Finally, after a lot of months the build is finished. I posted here on the forum about a few issues that i encountered during the process. Mainly concerned around knock. We found that the ECU sometimes "thinks" that it hears knock after flashing it with EcuTek. When you remove the 2 connectors to the ECU (in the passenger side footwell) and reconnect them after a minute - it's gone.

Another issue was the water hose on the driver side. This new hose on the AAM kit runs just 1-2 inches above the exhaust manifold. It worked well for a few months but then started leaking. I replaced it, rerouted it and protected it with firesleeve.

Then at 11 psi, my clutch let go. This was my fault, I had the Z Speed easy street clutch, which is fine up to ~400wtq but can't do anything above that. I replaced the disc with a ACT heavy duty 6 puck and this is holding up great.

So, the current status is that I am running 4 boost maps, being: 6 psi / 8-9 psi / 10-11 psi / 12-13 psi. I didn't prioritize putting it on the dyno yet, but I guess that i am well above 500whp. I did a 60-130mph pass in just under 7 seconds at 6.93. For reference; a Q60 with tune and bolt ons does 9 seconds, a stock GTR around 7.8s, a Dodge Charger hellcat around 7.6 seconds and a 911 turbo s around 7.2 seconds.

For now, I'm enjoying the car as is on 93 octane and will probably just do minor upgrades here and there to perfect it. Drove it again on the Nürburgring and had a blast, 187mph on the autobahn on the way back was fun too.

I have some video's and photo's on Instagram: @Boosted_Fairlady - feel free to follow me there as well!
I will post the dyno results as soon as I can be arsed to go there ;-)
