Turbo Upgrades

The JMTCs S45 F56 turbocharger was designed with the street and track enthusiast in mind. We started with our huge 50mm compressor and upgraded quick spool 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 but deliver much more torque and power.

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 43mm turbo. If you are looking for a great street, track, or strip upgrade that delivers full race performance this is the turbo for you. Don’t be left at the starting line by any other car and get one our S45 turbos today.

S45 Specs

• 50/67mm Billet High flow compressor
• Quick Spooling 45/40mm High Flow exhaust turbine
• High strength internals with 360deg bearing
• Designed for higher pressure and high temperature turbine housing
• Water cooled bearing housing and quick spooling dual scrolling housing
• New electronic wastegate actuator (new turbo only, DV/BOV not included)

Requirements

• 3" full exhaust (to increase life of the turbo and the engine)
• ECU tuning (to increase preset power due to ECU load limits) - Please contact JM Turbo Cooper for local and regional tuners that require a custom tune for it to perform. JM Turbo Cooper
• One step colder spark plugs
• New oil supply line (to increase life of the turbo)

For engine and turbocharger reliability reasons JMTC requires a 3" or larger exhaust (from turbo to exhaust tip, no exceptions). As well as installing a new oil line and one step colder spark plugs. Tuning is not required but will be will help the turbo and engine reach their full potential. Price Includes the core charge of $250 that will be refunded when a rebuttable core is returned to JMTC. Refurbished turbos do not come with a wastegate actuator or one that has not been tested.

Vargas builds on their stock replacement turbo kits with this Stage 1 upgrade. Using the stock housings but with improved internals, this N54 turbo upgrade is good up to 470whp. Stage 1 is a hybrid of stock and upgraded internals - a new larger higher-flow cast compressor wheel matched with the stock turbine wheel. The Vargas stainless wastegate arms are also part of the rebuild. The Vargas standard rebuild is good up to 400whp so Stage 1 gives you a more capable turbo system to match your upgrade goals.

Vargas Turbo Technologies has been in business since 1979, offering rebuilt and re-engineered turbo solutions. With the N54, they identified a need for both cost-effective turbo replacements and proven turbo upgrades. The biggest complaint on N54 turbos is the rattle from the wastegates. The factory wastegates have actuator arms that lose their tension very easily, resulting in an annoying rattle. N54 wastegate rattle is the biggest complaint we hear from our customers. Vargas rebuilds each turbo assembly with OEM internals and replaces the actuator arm with a stainless steel arm of their own design. Because the Stage 1 uses stock BMW/Mitsubishi turbo housings, all of the stock turbo plumbing and intake hoses will match up. It's recommended that the rest of the system be upgraded to handle your tuning goals. The final Vargas rebuilt turbos are better than the factory rebuilds and at a lower cost!

Two other upgrades are also offered for Stage 1 -

• TD04 thrust bearing upgrade - stronger and 30% more surface area than the stock thrust bearing for better bearing life and less stress
• Billet Aluminum compressor wheel - stronger and more efficient compressor wheel than stock for 20% better airflow

Silicone inlet and turbo manifold pipes are also strongly recommended as upgrades over the stock plastic and aluminum pipes. Since both are prone to cracks, the silicone will be a lot stronger and almost no chance of a disappointing boost leak. Turbo replacement is the best time to add the silicone hoses. There are two styles of turbo inlet pipes - with stock diverter valves (DV) or with aftermarket blow-off valve (BOV). For the turbo manifold, there is no standardized connection to the intercooler so you will need to make note of which type you have and select the appropriate adapter from the options list.
Option A (+$25) - 2.5" and 90* turn up from the intercooler (CPE, AA, ER Sport, CXRacing)
Option B - 2.5" and angled up from the intercooler (AD Engineering, ETS, Helix, Cobb, ER Compeition)
Option C (+$25) - 3.0" and angled up from the intercooler (VRSF)
Option D (+$25) - 2.75" and angled up from the intercooler (Wagner EVO)
Option E (+$50) - 3.0" and straight out from the intercooler (AA Race)
Option F (+$25) - 2.5" and straight out from the intercooler (Forge)
Option G (+$15) - 3.0" and straight up from the interooler (AMS)

Install Kit - an Install Kit is also offered that includes all of the additional parts and pieces that will need to be replaced during this install (gaskets, hardware, etc).

Oil Recommendation - modern engine oil is formulated for emissions and to be environmentally friendly. The additives in current oil lowers the oil's ability to withstand high temperatures and stresses, lowering its shear strength and its lubricating properties. Vargas recommends oils with high ZDDP (zinc and phosphorus) content that will better protect and cool the turbo bearings. Examples of high-zinc oils are Red Line Race, Red Line Euro, Motul 300V Racing, Joe Gibbs Racing, Valvoline VR-1 oil, and most Diesel-spec oils that you can buy off-the-shelf. Some oils, especially the Race type, will need more frequent oil changes and may be harmful to catalytic converters.

WHP rating: 470. This rating is used to compare various stage of Vargas turbo kits. There is no advertised horsepower gain with this kit as it depends on your other mods and tuning. The rating is provided as a reference to use in your tuning planning. Custom N54 tuning is recommended to match these turbos to your existing mods and upgrades.
