Turbocharging

We have a wealth of experience in Turbo Charger Engineering, and a s a result, we stock a comprehensive range of standard and modified turbochargers for all Renault turbo cars. It is best to contact us with your exact requirements, whether for Race or Road, and we will have a good solution for you. We also stock uprated actuators, high efficiency all alloy intercoolers, aeroquip feed pipes, re-inforced group A turbo hoses, silicone turbo and water hoses, and in-car boost adjusting kits, both mechanical and electronic.

All Turbocharger Hybrids are carefully designed according to airflow and pressure requirements. They are generally designed to be able to run reliably at higher boost pressures, higher compressor efficiency and produce higher air flow outputs. They will normally make a vehicle feel a lot more responsive with less ‘turbo lag’, increase the torque throughout the rev range as well as increase the power output from the engine at lower RPM levels. Some hybrids are available ex-stock, some specially built to order and some require the customers’ original unit for conversion.

Modifications – all the following hybrids are designed to be capable of running higher than standard boost pressures and are fitted with a standard actuator set at standard boost pressure unless stated below or requested. On most applications, some engine modifications are advisable such as a larger bore exhaust/flowed head/fuelling/high flow intercooler/oil cooler.

Other Options
Left hand thread shaft, martinite M247 turbine wheels; titanium nitride piston ring seals; enlarged oil feed capacity Group A 360 degree thrust bearing; lightened ‘low noise’ race journal bearings; rally specification hard anodising of compressor wheel; two stage boost facility; choice of up-rated actuator.

Ceramic Ball-Bearing Option
Available for T3 and T3/T4 turbochargers in standard or hybrid trim. This new technology ceramic ball-bearing design allows rapid ‘spool up’, excellent transient response and durability. The design practically eliminates thrust bearing and operational surge failures. This system can handle 50 times more thrust loading than conventional turbochargers, making it ideal for severe transient and extreme pressure ratio applications.

Standard Replacement Turbos
We stock standard direct replacement turbos for all Renault cars. Please refer to our Parts List for further information.

Prima Racing reserve the right to revise, change or modify any of the turbo specifications listed.

Hybrid Turbo's & Accessories
The following information refers to our preferred list of Hybrid Turbochargers. 

Stage 1 and Stage 2 turbos in the main, can be fitted to standard engines. Stage 3 turbos upwards typically MD28, MD84, MD84R, need modified intercoolers, Group A carburettors, improved induction and exhaust systems.

More importantly engines need to be in good condition and capable of running the boost pressures quoted.
