ARTEC PERFORMANCE Nissan KA24 V-Band Exhaust Manifold


All Artec manifolds are designed using CFD software to ensure they maximize flow, which, in combination with their revolutionary cast stainless steel construction, ensures that not only do you get he most power, but also the most reliability.

Artec says that this manifold was designed as more of a “gut” feel. Knowing that there are so many people who still have the KA24 in their 240’s and that there are many people, like yourself, that want to upgrade that engine and don’t want to do the usual swaps. Artec’s designer said “I’ve always liked the KA24 with its high comp, larger capacity and flowing head. It just seems to get pushed aside for the SR, probably due to the fact the SR came with a turbo. But once you go E85 and the basics on the KA24… KAPOW!! what a beast.”

Artec spent plenty of time optimizing the transitions from the OEM square port to the 36mm ID runners, up from the 33mm runners on the SR20 and Evo designs. This was due to the increased compression commonly seen on KA24 builds and the OE specs, as well as the 20% larger capacity per cylinder.

Some of the design features include correct design for LHD cars with proper clearance for a brake booster and the master cylinder lines, as well as the Hicas pump running off the power steering pump. The wastegate has also been placed in such a position that allows for easy plumbing back into the down pipe or just venting to air.

The KA24 manifold uses Artec’s patented V-Band system that will accept all 50-55mm V-band turbos and is designed to run standard rotation direction. You can run @precisionturbo units or @garrettmotion  from G25’s all the way up to a Precision 6870 or G35-1050.

The wastegate size suits any of the common 44/45/46mm wastegates from companies like @turbosmarthq @gofastbits @tialsport and others that share that footprint.
