CTR head?
 

Hey everyone I am looking at going to pick up a GSR block along with a CTR head today I was wondering how do you denote that it really is a CTR head? Is something stampped on the block that will tell me thats what it really is? Thanks everyone

RE: CTR head?
 

the block will say b18c1 and the head will be stamped pr3 i believe

RE: CTR head?
 

you won't know for sure without taking it apart. CTR, ITR, B16A heads all say "PR3" on the outside. Same casting, different insides.

RE: CTR head?
 

Yeah I know how to tell the block, but okay I will look for Pr3 then, I figure I know how to do the swap part now I might as well get a motor to build as a winter project because well I have never rebuilt a motor before, so my grandpa told me he would coach me along with how to do it. But hey I know how to do most of the other stuff so I might as well learn how to rebuild the motor right? And whats better then picking up a GSR block with CTR head, and how would I tell if I take the valve cover off though?

I can't say what's better because I don't know what your goals are.

Take a look at this

and this

if you are going to rebuild an engineanyway, just buy a bare head, CTR cams (if that's what you want), whatever valves you want, etc. etc.

Well I am leaning towards going the boosted route seeing how I already have a N/A motor. I am planning on tearing this motor all the way down and beef up the internals then getting a nice turbo kit for the car. But if I can get the head for a decent amount I will probably go ahead and get it then sell off the parts.

I know its going to take some money and work but I am looking for about 400hp roughly give or take some. I am sure I am going to be hitting the books since I dont know much about turbos

RE: CTR head?
 

hit the books before you spend any cash.

RE: CTR head?
 

Well I am guessing a GSR block is the best place to start so I know where I can get one for a good price so I am going to pick that up
