Toyota 1JZ Engine Parts & Upgrades

When embarking on a tuner car project, sourcing reliable and high-quality parts is paramount. For enthusiasts of the legendary Toyota 1JZ engine, finding a reputable supplier for engine components and performance upgrades can sometimes feel like a quest. Whether you're building a drift car, a track machine, or a street-slaying beast, the 1JZ platform offers immense potential. This article delves into where you can acquire essential Toyota 1JZ engine parts and explores exciting upgrade avenues, particularly focusing on the popular 1JZ-GTE twin-turbo setup.

Upgrading Your 1JZ-GTE Twin Turbos: A Deep Dive

The 1JZ-GTE engine is famously equipped with a sequential twin-turbo setup, typically utilising CT12A turbochargers. While these units offer a responsive initial spool, many tuners aim to extract more power and improve reliability. A popular and effective method to achieve this is by upgrading the stock twins.

The Turbo Rebuild and Upgrade Process

A comprehensive upgrade service is available for your 1JZ-GTE twin turbos. This process involves sending in a rebuildable pair of your existing CT12A turbos. The service includes a complete disassembly, followed by thorough cleaning and bead blasting of all housings. Crucially, brand new Inconel (a high-strength steel alloy) exhaust wheels and shafts are installed. To significantly boost airflow and performance, the compressor housings are then bored out to accommodate a pair of brand new Billet GTX 11-Blade compressor wheels. This upgrade is lauded for delivering a BIG improvement in both power output and overall reliability.

Achieving Over 400WHP Reliably

If your goal is to reliably achieve over 400 wheel horsepower (whp) on a stock twin turbo setup, this specific upgrade is precisely what you need. By enhancing the efficiency and airflow capabilities of the turbos, you can push the boundaries of your 1JZ-GTE without compromising its longevity. The price for this service typically does NOT include the core turbos; you must provide your own rebuildable units. An added benefit of this upgrade is that the wastegate and exhaust control ports are bored larger. This modification helps to mitigate issues like boost spikes and over-boosting, which are common ailments of stock turbo setups, leading to a more stable and predictable power delivery.

What to Send and How to Package

When shipping your turbos for this upgrade, it's essential to send only the two turbochargers along with their associated wastegate actuators. You do not need to include the 3-port cast exhaust manifolds, any oil or coolant piping, or the centre collector. Sending these extra components only increases shipping costs and the risk of damage during transit due to added weight and bulk. To ensure the safe arrival of your turbos, it is highly recommended to package each turbo individually. Subsequently, double-boxing them together provides an extra layer of protection.

Inspection and Communication

Upon receiving your turbos, they will be thoroughly inspected. You will be advised if any parts are deemed unusable before the upgrade process commences. It is vital to provide a clear and accurate contact phone number so that the service provider can easily reach you. Remember to print your invoice (e.g., from Driftmotion, if that's where you're sending them) and include it inside the box with your turbos. Ship your turbos to the address specified on the contact page of the service provider's website.

Packaging Tips for Safe Transit

Proper packaging is critical. If you don't have access to specialised packing materials, use plenty of cardboard strips wrapped securely around the turbos. Double boxing is strongly advised. Avoid sending coolant piping, oil piping, compressor inlet pipes, or any exhaust parts that are not integral to the rebuilding of the two turbochargers. Careful packaging protects your investment and ensures the service provider receives the necessary components in good condition.
