i haven't seen a single person compare them.......

Yeh, I've been running Skunk2 Ti retainers for the last 18 months in my build.

I can't see running Type-S pistons with S2P2 cams being any problem. I run the S2P2 with my Mahle Gold Series 11.5:1 pistons with no issues whatsoever..

Im also researching on some good cams, and now Im kind of leaning towards the Skunk2 Pro1's with a stock bottom end and valvetrain. Also Whats are a good size Throttle body with a stock h22 manifold?

NirVTEC

Because of the issue that Mahle had with its 1st run of H22 pistons, they did some work on the valve cuts. Just because the compression is higher than the typeS, doesn't mean they will automatically be OK.
i haven't searched too hard, but I can't seen to find any issues with S2S2/S2P2 and TypeS/ATR pistons.
If anyone finds a thread, let me know......Because of my friends success, I am assuming they are fine.
Again, his setup is H22A-R and S2P2s....

You'll wanna upgrade the valvetrain if you run the pro1 cams.

I have these cams, and I'm going with a Supertech valvetrain as well as flat
faced valves and s2 cam gears when I get the money together.

Is skunk2 even selling the s2 anymore? I haven't heard anything about them in a while.
All i hear people talking about are the p2's.

EG_Ferio93

Supertech valvetrain? Ive only heard about Skunk2 valvetrain, is supertech any good.

NirVTEC

IMHO its better.....but the SELL for me was the stiffer seating rating.
There's absolutely nothing wrong with S2 VTs though. I used it for a couple years and decided to switch to SuperTech with the addition of my JUN cams.

EG_Ferio93

Are there any certain size valvetrain I'm suppose to look for? because I was on skunk2.com looking At the retainers etc. They had different sizes. I don't know which one to go for because of my engine hasn't had nothing done to it.

NirVTEC

Don't bother then......Use the money for something else.

What about DH-racing camshafts stage 2? Can anyone give me feedback on them?

NirVTEC

Do some research. I think DH-Racing had some issues with delivering...

EG_Ferio93

I did some research couldnt really find anything, not unless Im looking at the wrong things. What you do mean as in delivering? as Hp and Tq or as in Shipping issues?

Do the oversize pistons. You'll probably want a fresh bore anyway.

FearDisH22a4

yes i was thinking of going with the OS type s pistons, but after doing some more research on them im not so sure anymore. On preludeonline they were talking about the type s pistons and valve relief angles. they said that the USDM head have a different valve relief angle then the JDM type s head. And by putting type s pistons with a USDM head isnt a good idea. Is there anyone that thinks different? I need info ASAP i have the motor completely apart and i need to decide on some pistons so that i can send it out to a machine shop. Thanks guys

Im going to be sleeving the block with Darton to 87.5mm and using CP pistons 11.5.1CR.
Does anyone have these pistons now?

FearDisH22a4

Well ran into some issues. I ordered some ACL main,rod and thrust bearings. When i measured the main bearings they come out to be Larger. The tunnel size for my h22a4 is 2.125 and the tunnel size the ACL bearings would fit came out to be 2.322-2.323. I called ACL and i explained what was going on and they said that the 97 h22a4 have the older h22a1 cranks and that they are a different size than the 98-01 h22a4's. Same go's for the thrust bearings. the rod bearing work fine. They didnt even know about the problem untill we addressed it to them. Has anyone ran into this problem?

Another issue is i was going to get some new rocker arms and some new OEM retainers at the Honda dealership. They said that they only had 5 rocker arms in stock and 1 retainer and they thats all they could get. they said that Honda stopped making them. Any suggestions on what i should do.

I called skunk2 and asked them if i could match up OEM retainers with the skunk2 pro2 cams and they said that i might have some clearance issues with the rocker arms. Is this true?

Titanium retainers nowadays should not be an issue. My friend had 40K miles on his without any signs of wear and my H23 Ti retainers have 55K on them with 2000+ road racing miles on them and high lift (.450") cams and still look fine. You just need to make sure that they are a good fit to the springs and that they have a good surface finish (no deep scratches or heavy burrs).

PirateMcFred

Oh and something I don't see in your list is a manual timing belt tensioner. You'll want that.

FearDisH22a4

why manual timing tensioner instead of auto?

Nice, so what were your friend's final numbers? Did he have a Euro-R intake mani on that setup?

0Janet@bisimoto

The answer is a little more complicated than that. Some manufacturers use low quality titanium from China. Since they are made of inferior quality they tend to weaken with use and eventually warp. Another contributing factor is high spring pressure. If they are made of lesser quality material (titanium) they will also warp. However, our titanium retainers are heat treated so they could last the life of the engine. Also, remember if you have an aggressive cam with a stock valve train, the same thing is true: the retainers will also warp at a few thousand miles.

some one recommended me to cccylinders. so i emailed them and i told them that i had a cleaned and disassembled head that would need port and polished and need a complete valve job. i also would need supertech valve guides to be installed. they emailed me back and told me that if i would send the head in the next five days that i could get it done for 600. they are located in california. have any of you guys heard of this company?
