hi all, i know its not all that important, but i have just purchased a new engine that is being built for me, the car is a 98 sti, the changes are:

• new sti open deck lump engine bored at .5mm and honed to a crosshatch finish (now a 2.2) not 2.0)
• Mahle forged pistons at .5mm
• full decat system, later spec intercooler,
• running 1.2bar boast.
• walhro pump,
• stage 1 exeedy clutch

Just wondered if i could get an idea as to what sort or power it will have..

What turbo are you running?

could be anything mate. all depends on heads/cams turbo charger, injectors and what other mods have been done.

anything from 300 to 340 with that boost level.

You engine is not a 2.2, it is very slightly over 2 litre in capacity using .5mm oversize pistons in a EJ20 open deck block.

well the guy thats building it stated it a 2.2 so only going by what i have been told but thats for the heads up, will call him

as for the injectors and turbo they are standard

You would need the EJ20 to be relinered with 97mm pistons or a EJ22 block to get a full 2.2. However if you have a EJ20 and user a 2.5 79mm crank with stroker rods and pistons you can get 2.1, which is sometimes called 2.2

Standard turbo will be a VF24 and 440cc injectors, so may see between 310-320bhp.
