Subaru STI (EJ25) shortblock rebuilding
If the engines are subject to misuse or pressure too high you may damage the lines is then necessary to replace the cylinders with new more resistant ones, This procedure is very complex and requires much experience.
In addition to this possibility, we have recently completed a special flanging of the engine block (ej25) where you can get a very high overpressure, equal to 2.50bar , without the need for "sleeves"
