Head Rebuild

The link didnt work for me. But I found it. Thanks man.

Springs are easy to install. Just have to compress them down, take out the valve lock, take off retainers/springs. Install is opposite. Much easier with head off the car as when you compress the spring, you have to make sure there's clearance with valve-to-piston.

And for Joe... not really. Without any major upgrades, the stage 3 is going to be over kill. Your idle is going to suck, DDriving is going to be hard, and you won't get that great of performance IMO. You really need a turbo for those grade of cams, and be using it as a drag car. However, it's up to you. So unless you're building it up, stage 2 is fine. What do you plan on doing with it? Full build?

please say yea, please say yes. Lol, I wanna witness someone building up a 420a.

You will completely kill the powerband on a stock 420a with Crower 3's. You'll need some high compression pistons and a good tuning system to make them produce any power.

Fixed the link.

LOL, here we go. I wanted to have the head with stronger valves, springs, cams, gears, porting (myself) and all new seals. First step in beefing up teh 420A would be the head, I want to make it bullet proof. Next I want to drop a turbo in it, running 8psi at most. Last but not least I would move on to the engine block, upgrading the piston components and getting anything lightweight. Hell I'd probably get rid of the AC all together. What do you guys think?

***EDIT***
Can't forget a management system, didn't really want o go into specifics.

I would say build the block and turbo at the same time. Ya, you're going to build the head. That's fine. Gets you more power. Then if you turbo, you have a built head with a stock block with x amount of miles on it. Somethings going to break. Would be best to build a block that can handle a turbo, slap a turbo on it, then put the built head on. When I do mine, that's how I'm doing. Plus if you do it like that, you have to install the turbo and the head twice.

A/C is easy to get rid of.

You may want to sit down, come up with exactly what you want to get in parts, (being realistic) and we'll go from there. Do you know turbo you're going to run? HOw much hp you looking for? Lots of questions.

[bleedEGLblue]

Too many questions lol.

Actually, you're going in reverse. The stock 420a head can flow very well, and support a good amount of power. IIRC, Hahn was running a stock head on his car when he was in the 11's or 10's. That just goes to show that you don't need to start with the head.
If I was you, I'd start with the block. New pitsons/rods/rings and maybe an overbore if you want, but that's where I'd start if I were going to start over with my RS.

Sorry to keep you guys in the dark but my bonus for the year hasn't come in yet, should be anywhere from $600-$1400. I usually get it the second week of Dec, but nothing yet.
Anywho I just dropped a buddy off in Lafayette, that was $700 in pocket now. My sister paid me some $300 she owed me so I am sitting at $1k in my hand. I'm still waiting for that bonus before I begin, is it enough?

I will pulling my block out, per Garrett, and replacing components. And the valvetrain too, all the stuff we mentioned above.

Depending on how much you have to spend, building the motor and going turbo at the same time is a good idea. If you can only do one right now, put the turbo on first. If you build the motor and dont turbo it you will be left with one slow ass low compression NA car.

[JoeShmoe]

Well seeing the pics of MazdaX's engine block makes me weary that my enginge won't handle the turbo. I will have about $2400 in about a week.

Mine has held up fine for almost 15K miles now.
