Product Overview
The JMTCs S45 I8 turbocharger was designed with the street and track enthusiast in mind. We started with our huge 51mm compressor and upgraded high flow turbine to give you full boost quick and a huge amount of power at the top end. We also designed it to maintain the quick response of the original turbo, deliver much more torque and power and give you around 265 (stingy dyno) to 312bhp (dyno jet Engine only with supporting upgrades and tuning) and 460bhp with electric motor.
This turbocharger not only delivers high torque in the low to mid-range but you will also see a power increase at higher RPM. No torque or power loss like you see with the original small 40mm turbo. If you are looking for a great street, track, or strip upgrade that delivers full race performance this is the turbo for you.

Note,
Tuning is not required but will help the turbo and engine reach their full potential. This turbo requires full 3" exhaust and can be damaged if a smaller size is used. This turbocharger has been machined, welded, and hand worked to fit the larger wheels, there are No refunds for these intentional changes! Check with the installer before you purchase, we will not refund for intentional work we do to upgrade the turbo. the Electronic wastgate is bench tested not real world tested so some adjustment may be required. Also the refurbished turbos come with a refurbished or previously used electronic wastegate. We bench test them however they are not real world and heat cycled so we do not know the condition. JMTC will provide another WG if it is not working under our warranty. If you want to eliminate this issue purchase a new WG with the turbo and we will pre-install the new WG at no extra charge. You can also use the original WG on your turbo if it is working. Price Includes the core charge of $1000 that will be refunded when a I8 turbocharger (core) is returned to JMTC.
