Valvetrain and Crankshaft question

Ok, I have two questions for you.

First off, i have the whole head appart i am just having some trouble getting the valve springs out as the seals need replacing and also the head is going to be ported and polished.

Secondly, i am also having trouble getting the timing gear off of the crankshaft, its the only thing left holding the crank in place.

thanks for any help

BTW, These are my plans...

ca20 block + head ( mechanical valve train )
ported / polished head, ported intake manifold, ported / polished Ex Mani.
oil cooler
i am going to start off with a T2 turbo at stock boost, eventually i will get a t25 + intercooler. my HP / Torque goal is around 170 - 180 hp and 170 torque.

sounds abouyt good. Your going to be pushing the t2 really hard and with no IC...i dont know how long it will last. But you will make your #'s if you boost it high.

As for the crankshaft sprocket, you just have to hammer and pry it off. It took me 2 days + 2 friends + a torch + greese + sandpaper + other ghetto ways of trying to get it off. Just hope yours isnt as bad.

ok, so just some brute force then, and i wont be running 180 hp right off the bat, thats when the t25 and intercooler go in :)

No brute force should be nessary. If you take a close look at the timing gear on the crankshaft you should notice that there is a small "keyway" or "woodruff key" installed into the crank and gear. Its there to keep the timing gear from spining any old which way it wants to. Now, you need to remove that first and then the gear should just slide off nicely. If you need anymore help I can provide pics.

trust me. I had that key gone that 1st step. Mine was actually rusted on. I ended up sanding the crankshaft shaft down just a little so it would slide off. Its not as easy as you think on these old engines. Some of them have some goo suprises.

Ok cool, i figured it had something to do with that key. Thanks for all the replies, i will be posting pics of the buildup as it progresses.

hmm i have never had any probs getting the 3 different crank pullies and timing gears sets off the engine i have worked on

well got everything apart, cleaned the block and honed it, now i am just waiting for piston rings.

My old CA20E? Aww...Nice to know it went to a good home. :-P

Oh yes, i am going to squeeze every last bit of horse power out of this beast and then road race at mission. My buddy james is helping me with it too, that bastard is getting an r32 skyline with an rb20 so i have to show him up with superior s12 drift action.

what kind of rods are you gonna run in your engine?

Dude...James is getting a R32!!!! Sweet!!!! I want one so bad....but with a RB26ETT of course.

Yeah, when he sells his honda he is importing an 89' gts-t r32.

and i am going to be running stock rods so i might take a little easier on the hp numbers, like 160 - 170. btw this is all being run on the ca18et ecu and electronics and oil pump / manifolds....

No CA20E Mani....do you want one?

Do you have one? What is the advantage to that manifold, i know that with the ca18 manifold you get more even air distribution for each cylinder.

it points straight ahead, so you can avoid nasty S-shaped intercooler piping.

And you don't have to worry about the heat off the heads, and exhaust manifold warming the air (as much at least) 8)

What they said....

Yes, I do have an extra one. It will be availbe for purchase within a month or so. As for price...:dunno
