Thread: Test results from Track Forged t3 top mount manifold

Stock manifold and throttlebody is enough to get you where you want to be and more.
Trust me

good to know kev. still will need larger injectors. I also did not even bother to clean up the intake and exhaust ports. the head is stock other that the springs and retainer. Like i said simple build just to see what would happen. would have gotten the stepped deck but mazworx had not started offering it to the public when I put the motor together. I may have a s13 project coming soon.

My head is the same, just I have SR16 cams instead of the 20v cams. It supported 641hp so far on my car at just 25lbs with the same turbo. I'm not sure if I will try for more but I'm satisfied with how well it performed so far.

I checked today and my Nx2000 radiator fit perfect. Just needed to rotate one t-bolt clamp so it fit right.

I know this is more about the manifold and numbers, but since it came up I have to ask about the nx radiator. How are you water temps doing with the stock nx radiator? Are you running 100% water? It's a single row radiator right?

temps were fine with the b13 radiator(6hrs on the dyno no over heating) but it developed a leak from the end tank. I run a 80% water 20% coolant and a bottle of water wetter. Temps will be better with the nx radiator due to the core being larger. I also run the nismo thermostat and made my own cooling plate.
