Soon iam going to start building my 2.0 OHC when i get this block i am going to oversize it 20 over and get all new pistons and rods ETC and of course i have my new 2.0 head a valve train so all i need to get is the block and get all the other work done then drop it in my car and go from there.
Do you plan on going performance aftermarket on the rods and pistons, or just stock. How about the valvetrain? If you have any plans on performance parts, I'd like to hear about them.
well the valve train is stock aftermarket becase the stock 2.0 eat cams and the new valve train has bigger oiling holes and that. and for the pistions i prob go for aftermarket.
Are you going to get the head milled? If you do make sure you get a thicker gasket or a shim. I had mine milled and now I suspect my timing is off because the cam sprocket is closer to the crank sprocket.
You can't outrun the radio.
If you mill your head then use a thicker headgasket, isn't that undoing what you did by milling the head? Why go through the trouble?
LUCKYDOG:thats a good question. i've always wondered that myself. isn't it like defeating the purpose?
People say that what doesn't kill you in this life
will make you stronger. I'm not sure if that is true
or not, but i do know one thing-You have to learn from
it and it has to make you better.......it has to.......
There are 2 reasons for machining the bottom of the head. 1) To provide a perfectly flat surface so that you have have a good seal between the head,gasket, block... and 2) to decrease the size of the top of the combustion chamber to raise compression and increase power. If you want to increase the compression ratio of your engine, you should think about new pistons, rather than having the head machined. Not a bad idead to have it surfaced though just to make sure everything is straight, no warping.
youd just be better boosted
I read this thread and... I have no idea what the point of it is
It was meant to confuse you Jim. Mission Accomplished!
yes it was to confuse you. lol. but iam got the head milled to get it flat and i will be putting forged pistions in it.
i may be wrong but boring smaller motors with turbos like the lt3, but i heard that there is some overheating issues with that.
