Show original supplier description
The Tomei ARMS MX7655 Turbocharger Kit offers significant performance improvements over traditional cast compressor wheels. This kit utilizes a CNC billet compressor wheel, meticulously machined from aerospace-grade materials. These lightweight, highly durable wheels feature thinner blades with a larger surface area, resulting in substantially improved airflow and quicker turbo spool. Constructed with a large-capacity, reinforced forged billet design, this turbocharger kit includes a total of six springs for precise boost adjustments. The swivel-type nipple allows for greater flexibility when routing hoses, and up to three springs can be combined to fine-tune the boost setup. Included in the kit are: 6 springs, gaskets, oil lines, studs, the J/B TURBOCHARGER ARMS MX7655 RB26DETT, supplied pickups, and supplied hardware. The installation is a 100% bolt-on process. However, please note that the TOMEI KA24DE turbo exhaust manifold and SR20DET exhaust component are required for the use of this TOMEI turbo. The product comes with a 1-year limited warranty.
