Henry installed a Tomei 274° 11.3 lift intake set in his new engine, a 2017 Maxima engine with 30,000 miles, into his 2016 Nissan Altima 3.5 SV. He noted that HR engines have longer exhaust duration cams, typically 254°, similar to RWD HRs. He mentioned that the 2007 Altima has a VQ35DE engine with specific cam data:
- Intake/Exhaust Lift: 10.0mm
- Intake/Exhaust Duration: 240º
- Intake Opens/Closes: 10º ATDC/70º ABDC
- Exhaust Opens/Closes: 50º BBDC/50º ATDC
He found that VQ35DE Nismo Spec-1 and Spec-2 cams offer increased operating angles and lifts. His setup aligns closely with Nismo S1 specs, opting not to use Tomei’s exhaust cams due to lack of EVC control in his ECU. He compared his setup with VQ35HR and ‘Revup’ cam data, and provided Tomei cam specs:
- Intake/Exhaust Lift: 11.30mm/11.00mm
- Intake/Exhaust Duration: 274°
- Intake Opens/Closes: 14°/80°
- Exhaust Opens/Closes: 80°/14°
Henry also customized his timing setup, used Tomei oval wire springs, and incorporated various other parts like VQ30DE intake cam bolts, 3gen exhaust cams, and VHR components. After extensive work, he successfully started the engine, highlighting additional upgrades like a 6-speed swap, NISformance stage 2 clutch, and Borla X pipe.
I adjusted the intake trigger wheel to match the standard position found in third-generation models.
I grinded down the wheel as is typical in an HR engine swap.
I utilized Tomei oval wire springs for the setup, which are taller than those in RWD HRs and match the height of third-generation models.
Additional Install Photos
I’ve added more pictures of the timing setup. I had to use VQ30DE intake cam bolts for the third-generation exhaust cams. I also painted the timing cover and opted to use the cover from my original engine because I prefer the style of VVT covers, similar to those found on GTRs and VHRs.
After countless hours of challenging work, it finally operates successfully. The initial startup was for the cam break-in, and it has a lopey idle.
