The factory S14 & S15 SR20 intake manifolds don’t allow enough air into the engine at high RPM. It’s too small & doesn’t distribute even air flow to each cylinder. From 6200RPM, no matter what size or turbo you use. The factory intake manifold hits its limit & can’t get any more air mass into it.

The factory S14 & S15 SR20 intake manifolds don’t allow enough air into the engine at high RPM. It’s too small & doesn’t distribute even air flow to each cylinder. From 6200RPM, no matter what size or turbo you use. The factory intake manifold hits its limit & can’t get any more air mass into it.

Okachan himself is using this intake manifold on his S15 Silvia. It can take up to 8500RPM, now there is no limitation caused by the intake manifold and the SR20 is able to get more air flow and mass in high RPM. You can see a huge difference in air flow & power gain in the dyno chart image. The pink line is the results after installing this intake manifold with the same turbo.

Cheap intake manifolds can’t distribute an even amount of air.
You will only get a decent amount of air going in the first cylinder and not in the other cylinders which causes damage to your motor. This will result in engine failure.

This intake manifold has a funnel/trumpet design for each runner. This makes sure that each cylinder is getting an even distribution of air.
