Hi all! just a coupe(?) of quesions with regard to fitting a 2.5 sti short block i have.
1) Theres an extra breather by the water cross pipe,do i use it or blank it off?

2) Is it worth getting a lightened flywheel? Got my eye on a exeedy one,which isn't supper light,but i'v heard if it's too light(4.4kg) then it will idle badly cos it's a 2.5.

3)Am i able to run it in using the standard ecu? I've heard different veiws on this!

4)Should i use an expensive good quality oil during the run in period,only to change it shorly?

5)Last quesion,sorry! Will i need to fit 'cold' plugs? Any ideas which ones?

1) = blank that breather off.

2) = The light flywheel is up to you, i have 6kg one on mine.

3) = Yes the factory ecu should be fine with low boost but you must use it with your factory injectors. Mines a ver3 sti and i ran mine in on the factory ecu for 6000k's befor i got an aftermarket ecu.

4) = It's normaly addvised to use a none synthetic to help it all bed in and is what i did for the first 1000k's

5) = 6's will be fine. It would depend one how much power your looking at.
