Peugeot 208 GTI – Stage 4 RCZ turbo kit

Combining a THP200 engine with upgraded parts is always good. Specially if you take an RCZ turbo, a front mount intercooler, a full exhaust and Water-methanol injection, the combination can bring fantastic results. With 300hp at the flywheel on a stock engine, what else could anyone ask of their THP200? The power gains are just crazy.

How it works

The bigger turbo helps with power at high rpm. The front mount intercooler controls intake air temperature. The full exhaust gets rid of unwanted backpressure, making the whole system more efficient. The Water-Methanol Injection kit cools down intake air temperature and improves the fuel’s octane rating.
To top it all, the THP200 cylinder head systems makes sure that performance is consistent all the way to the rev limit. Variable cam timing adjustments and valve lift adjustments ensure that the car behaves as if it was on upgraded camshafts.

Remap parameters
The remap combines torque remodelling, cam timing and valve lift modifications, injection modifications, ignition modifications and boost management hacks. Operating at just 1.4bars across the rev range with 1mm of valve lift higher than stock, the power output climbs smoothly to 300hp at the flywheel.

    • S Alex Posted July 28, 2018 9:50 am

      That depends on your turbo setup and the nozzles that you are using. What power do you expect the car to make and what boost levels are you operating it at?

    I have a question about the gearbox. How much torque will it take. I have looked around and information about the gearbox is really hard to find. Thank you in advance.
