Etuners – recommended upgrade stages for the Peugeot 207

These are the recommended upgrade stages for our beloved Peugeot 207. We strongly recommend making sure the engine is in good health before remapping. All the common problems THP engines face need to be addresses and proper maintenance needs to be done. Using a remap on a healthy engine will produce incredible results and lots of fun for the driver. Using a remap to compensate for power lost due to engine malfunctions is a poor way of dealing with the problems that may be hiding behind them.

THP150 – Peugeot 207 1.6T XS / GT / Rallye / THP150 (engine code EP6DT) and THP156 engines (EP6CDT)

  • Stage 1, when the only upgrade is an ECU remap and everything else is kept stock. Performance reaches 190+hp on 98RON fuel from 150hp. One more example here.
  • Stage2, when an intercooler is added to the car. With the larger ic added,  power delivery can climb to 200-205hp.
  • Stage3, when the car has fully upgraded peripheral parts such as: cold air intake kit, front mount intercooler, upgraded exhaust and potentially water/methanol injection. Power levels rise up to 220hp, which is the maximum that a THP150 turbo can produce on good fuel.
  • Stage4, with hybrid/big turbos installed on a stock engine along with everything else from stage3. Power levels depend mainly on the turbo, but in most cases are over 250bhp but below 300bhp.
  • Stage5, when we have hybrid/big turbos along with upgraded cam shafts installed on a fully built engine. The stock engine cannot withstand this level of power. It is possible to reach power exceeding 400bhp, everything depends on the exact setup.
  • When THP150 engines receive a THP175 turbo from the Peugeot 207 RC/GTI, they also get upgrade levels from them.


THP175 – Peugeot 207 1.6T RC / GTi / THP175 (engine code EP6DTS)

Because the RC/GTI has a turbo with a larger compressor wheel, it can produce more power compared to the THP150. The stock intercooler unit is the same between THP150 and THP175, so the bigger model overheats and loses performance even as stock on relatively warm days (ambient temperature around 20C).

  • Stage 1, when the only upgrade is an ECU remap and everything else is kept stock. Performance reaches 205+hp on 98RON fuel from 175hp.
  • Stage2, when an intercooler is added to the car. With the larger ic added,  power delivery can climb to 220hp.
  • Stage3, when the car has fully upgraded peripheral parts such as: cold air intake kit, front mount intercooler, upgraded exhaust and potentially water/methanol injection. Power levels rise up to 230hp-240hp, which is the safe maximum that a THP175 turbo can produce on good fuel.
  • Stage4, with hybrid/big turbos installed on a stock engine along with everything else from stage3. Power levels depend mainly on the turbo, but in most cases are over 250bhp but below 300bhp.
  • Stage5, when we have hybrid/big turbos along with upgraded cam shafts installed on a fully built engine. The stock engine cannot withstand this level of power. It is possible to reach power exceeding 400bhp, everything depends on the exact setup.
