Sup guys, I've got a couple of questions for those who have experience with Type S internals. I've got a stock H22 head (dunno what bottom end), and was planning on rebuilding it with new valves, seals, springs and retainers (stock), but I was wondering if I were to put the Type S cams in the head, and the corresponding pistons into the block (I plan on rebuilding the bottom end soon), will I need to do anything other than get the ecu retuned? Also, does anyone know how to identify which head I have, exactly? I ask because I remember reading something about clearance issues with Type S cams in the A1 head.

IMO no, just get stiffer valve springs
maybe adjustable cam gears

people put crower and skunk2 cams there also and theyre much more aggressive ones than those type s ones so why there would be any issues?

Well I heard that the A1 heads have a problem with the retainers smashing into the valve seals or something, and the rocker pads getting worn quickly, or something like that.

Type s pistons can go in without any other modification. Type s cams are a good idea to do with stiffer springs and retainers, but this is on an a4 block, and its pro lay the same for an a1 but I don't know for sure. I don't know which bottom end you have but you can find it stamped on your block next to your slave cylinder if you have a manual tranny. If your in the US chances are you have the a4. And if you want a good deal on type S pistons check the link in my sig!

My block is the original H22A1 that came in the car off the factory floor, but the head in my trunk is of unknown origin, lol. I'd like to pick those pistons up, but I don't think my motor needs to be bored, and there's no shop within reasonable distance that I think would be competent with an H22's sleeves.

Yeah, but I'm not trying to go crazy with this thing, lol. I'd drop at least another grand on turbo parts before getting to use it... All I want is to bring my H back to it's original glory, with a little more pep in it's step.

well no matter what you do your going to want to put a fresh hone on your walls, but if you dont have a shop that will do your FRM walls near by then yea your in trouble.

A friend of mine built an H22 about a year ago, and the shop where I had my KA24DE head done honed his block. He had to buy the guy the stones and give him the procedure, but he did it. I was told, "Fair warning he isn't gonna want to do the work lol he said it was a pain in the ass"... so I'm not looking forward to this. On the plus side, I found a guy about 2 hours away who has two bare blocks laying around. He said he'd trade me one for a copy of NBA 2k13 for PS3, LOL.

any shop that works on porsche motors can hone your block, no issue.

You say that like shops that work on Porsche motors are on every street corner, lol. I'll keep my eyes and ears open though.

New Orleans is bound to have a porsche repair shop. Usually cities where mega wealthy people live have one.

There are a couple of places, yes, but I fear how much they're going to want just to hone the cylinder and clearance the pistons.

just giving you another option, besides the guy that doesn't want to do it. I fear when people don't want to do something, that they won't take the time and care needed to do it properly.

Yes, but I'm not going to order standard size pistons, install them, then come to find out that my bore is out of spec once I check clearances. And at 229k miles, I'm fairly sure the bore has a lot of wear. If the motor only had 100k, I'd have no problem ordering pistons ahead of time though.

this was my downfall

Uh, what the hell do you do when your bore is out of spec even for oversized pistons?

Also, does anyone know how to identify Type S cams? I have a set that came with the head I picked up, but they look a bit funny. They're not shiny like my current cams, but rather a dark black color, like the blue finish of a gun. They also both have the letter "G" cast on them. As for their origin, the guy I got the head from didn't know, as the head came in a dufflebag with his car. They're very strange. Maybe I've got something good here, and don't even know it. Here are my stock cams, for reference. Notice how the back of the lobes are nice and bright, whereas these mystery cams are a black finish. I"ll get pics of the mystery cams this evening

I believe you scored type s. all the readings I've done say they are blue.

Bore no bueno for oversize pistons? Bigger pistons?

God's Not Dead

Here's the pictures of the cams in my possession the color is a but more pronounced in person. I'll get better pics with a legit camera tomorrow:

Also, I've never had my.head apart... This questionable one has dual valve springs... Is that standard on all h22s?

__________________

bigger oversized pistons

Nobody that I know of makes FRM friendly pistons over .25mm oversize. That's the limit you can bore the cylinder as well. I guess if the bore is worn even further, the block is junk without being sleeved.

__________________

guess what I did

standard size all the way. blindly .....we'll see what happens when we rip everything apart and start to measure things

yes they are

type r/type s/sir and 99-01 h22s have stiffer valve springs than other h22s
