Tomei Revisiting Nissan KA24DE 240SX Tuning

Japanese tuning firm and legends in their own right have gone back to the roots.  Their latest release is all about the famed Nissan 240SX and making more power out of the KA24DE.  Most 240sx owners will immediately do a JDM SR20 swap or even go the RB25 or RB26 route.  We hear ya loud and clear Tomei as when we built our Project 240sx, we stuck with the 2.4L and turbocharged that biotch!  So revisiting this platform will not just be 1 product, but a series of products, installations and tech articles to showcase this iconic cars tuning potential.  Their first big attack is with the new Tomei manifold.

This new manifold makes turbocharging the KA24DE very easy.  This manifold is designed to fit the KA24 engine block but will mount up a very EASY to find SR20 turbocharger.  This allows for the JDM turbo parts to easily bolt up to the NA engine block.  You can either use a stock or aftermarket SR20 turbochargers. The Tomei turbo exhaust manifold for the KA24DE features a dividing plate (just before the turbo flange) separating the port into left and right chambers. With the KA24DE firing sequence being 1→3→4→2 , this dividing plate allows for the exhaust gasses from each cylinder to be channeled alternately between the left and right chambers, reducing exhaust gas interference for a smoother flow of exhaust gasses to the turbocharger.

Take the Mighty GT-R to New Levels with Boost Logic"s Manifold

The Boost Logic VR38DETT Intake Manifold has been engineered to be the pinnacle of performance among its competitors. Benefiting from their extensive research and development in 2000hp 2JZ motors, they have achieved the goals set for this Manifold. An increase in torque to broaden the power-band while achieving a phenomenal horsepower gain under boost sets the Boost Logic Manifold apart from the competition.

On a direct comparison of Boost Logic’s manifold with a Greddy, they observed huge power gains while monitoring boost to be identical or lower boost on the Boost Logic Manifold. The gains are even more pronounced when compared to a stock manifold; especially the torque.

Engineering the manifold in CAD allowed the use of optimal dimensions and otherwise impossible angles determined to be ideal through fluid dynamics in comparison to a sheet metal intake manifold. Boost Logic aimed to maximize the potential of any engine/turbo setup so that this bolt on is beneficial for any HP package. The plenum size has been specifically calculated and sized for the VR38 to create the highest power gains in comparison to the stock and other aftermarket intake manifolds. The tapered venture funnel runners have been engineered for maximum velocity as air approaches the cylinder. Boost Logic chose to make the intake manifold in one piece to mimic OEM style manufacturing which will have less potential for boost leaks. The tube behind the throttle body flange is 80mm which will easily accept the Greddy throttle bodies or much larger units which will surely be developed in the future.

A unique aspect of this intake manifold is the newly designed lower runners. Casting these new runners allows it to maintain the linear transition from the aftermarket plenum to the intake ports on the head.

When it comes to maximum power, 6 injectors simply aren’t capable of providing enough fuel to meet the demands of ethanol fueled engines. Boost Logic is providing an optional third rail setup which will allow 6 additional injectors aimed directly into the intake port for accurate fueling. The 12 Injector Option will be an extra charge on top of the current intake manifold price. This will include a rail, brackets, extra machining of the Boost Logic Intake Manifold and will be pre-mounted to the plenum upon shipment.

We also offer the upper pipe kit for customers that change to this intake manifold. Due to plenum size and throttle body location change the upper pipes have to be modified. Boost Logic offers the one piece pipe upgrade for a simple install! Pipes available in polished or Crinkle Black.

The 12 Injector Option comes complete with fuel rail, mounting brackets and machined upper plenum for the 2nd set of injectors.
