In for the long haul Ultimate NA build thread. - Page 25 - Toyota GR86, 86, FR-S and Subaru BRZ Forum & Owners Community

I'm not sure the torque curve is the point of this build? The intent is to rev to 9000rpm and the only way to make NA power up there will be more lift via cams. The motor doesn't have variable lift unlike a VTEC so you'd expect the bottom end of the curve to suffer as a result.

I am very interested to see what happens with that inlet setup. Keep the posts coming celek!

What are you planning to do with that? I sense a lot of melting aluminum in your near future.

With the right valve lift, valve timing, and exhaust header, you can make the peak torque line up with your shift points. This results in a strong, steady pull after each shift. Because you're NA, the exhaust will be just as critical to performance, as the intake. This would be a real measurable difference you can measure at the track. It might take some trial and error with different Final Drives to find the best gearing, but it would be worth it.

Would you kindly make a CAD file of the port section of the manifold for us peasants who cant afford to buy sacrificial parts?

I made that 2 years ago from the stock manifold

I did not label it, someone must have swapped it or thought the manifold was EJ orientation when it was scanned.

SO I just got back from PRI in Indy Was able to sit down with the Piper guys good news they just released a newer better bigger Race cam!
That looks like the winner for the build.

Also spoke with an old time associate thats been building ITBs for 50 years. Worked out a game plan with Borla

That sounds awesome but how streetable or daily driver friendly would those cams be? Would you have crazy idling?
