A friend of mine is designing his own performance cylinder heads and was curious about the bore sizing on the 2.7 engines. Anyway here's his question as he wrote on paper for me to ask....

Do any of you know the bore and bore spacing of the large bore (2.7L) 4 cylinder DOHC engines? I am looking for something with a bore spacing of 111 mm.

Thanks!

 

I don't understand the question. Does he want the Bore size of the 2.7L? Does he need the sleeve size? Tolarances? What the heck does he want to know?

 

Bore spacing is the distance between the center of each cylinder. But I have not idea how much the 2.7 has.

The Bore x Stroke is 95mm x 95mm

 

i am a 2.7 owner. I dont know what your up to. But all i know boring means make it better by make the holes wider means more power. But hey! FILL ME IN ON WHAT YOU DO.

 

He's applying for a grant to start his own business making these heads, he's got some idea but I really don't know what it is. He tried explaining it to me but it might as well have been in Chinese

Anyway, all he wants is the distance from the center of one bore to the center of the next. (for the 2.7L)
Anyone know?
