OK, finally we manage finish our setup on a M20B25:
Ireland 2.9L Stroker kit
Schrick 288°
Big bore Trottle body 70mm
Schmiedmann header
Stock injector
Stock fuel pump
Stock air filter
MAF and WAR chip for engine management
225Hp and 291Nm
Dyno shows we have a limitation on the exhaust and cam to find more power, we could also have 3Hp more by leaning a bit our setup. Be choose to stay on a safe side.
Not bad, thank you MILLER!
