Alright guys. Haven't seen one of these threads yet so I decided to try to get one going. Lets see your H builds with OEM Type S Pistons. So we can see the power limit and potential of the JDM Type S Pistons. Dyno numbers, track times, helpful info and tips for other users.

My current set up isn't done yet, but ill put it up when its done

Alright guys, lets see em!!!

Not to be an A$$ but that grocery list you posted up there looks like it contains a wee bit more than just JDM Type S pistons only !

 

I dont see whats so confusing about it. People do builds with CTR and ITR pistons in B series correct? The only difference is im talking about H's and the JDM type S pistons.

 

I never said I was confused.

I merely pointed out that you are using more than just type S pistons in your build. And that you have asked for H22 builds that used "only" type S pistons. Does this clear up any confusion for ya.

That's all I was trying to say

That and the fact that the 6 of these threads posted per week are boring

That is a nice grocery list ya got there. Have you built it yet?

Oh that's right, you mentioned that your guessing that your list of parts may net you 11.5ish CR & 250ish Hp. So I will assume that this build is still in boxes on the store shelves.

Well good luck with your build

 

Don't worry about my "grocery list". If you dont have anything useful to post relating to the topic then go somewhere else with your BS. Anyways come on guys lets see them!

 

Bump for an interesting thread.

 

TTT Come on guys almost 100 views and no takers?

 

i think maybe utilizing an h23 crank will be a sure fire way to attain your goal.

 

I think I just might do that. Thanks for the advice. Although this thread im trying to start doesnt seem to be kicking off they way I expected. Come on people I know im not the only one who is using these pistons.

 

who did the work on the head?

 

Randy you got PM

 

The setup before I tore it down due to faulty piston ring scroing up cylinder #1:
h22 with type s pistons
h23 crank and rods
h22a head no porting
Skunk pro 2 manifold
Pro 2 cams
70mm tb
SSR Side exit

Made 235 hp 172 ft pounds before cylinder #1 starting losing a **** load of compression. PED was thinking it would of made somewhere between 240-250 hp. I'm now doing an f2b with the 97 crank hope to make 250+.

 

223.51hp 166.94tq

H23 crank & rods
H22 Type S pistons .025 OS
H22A4 head (no porting done)
Crower 3 cams w/ RM springs & retainers
Euro-R intake manifold
Professional Products 68mm ITR throttle body
shitty DC header (because i had placement issues with my race header)

 

also running type s pistons but on a h22 crank and rods

it is running a sk2 manifold,camp1320 header, sk2 stg 2 cams, skunk flat faced valves and a milled head,,,,,, hoping for about 12.0.1 cr and im running e85

this motor is in pieces right now lol

 

The H22 Type S Pistons have weak ring landings, just like all the H22 pistons. I made 240hp/180tq at the wheels on my H23VTEC - but the ring landings failed in all four cylinders at the first track day. Yes it was fully tuned, broken in, etc etc.

Here's a pic of the pistons after they blew:


It was a wicked setup while it lasted. I should have done it right - sleeved the block and used forged pistons. OEM H series pistons can't handle that much power

sorry to hear about that. What kind of piston rings were you running? Were those OEM pistons or the Nippon's?


I am putting together an h22 with type s pistons and I'll be running pro 1's with bolt ons looking for about 210 wheel. I'm using OEM rings and OEM type s pistons
the head got finnished this week and I'll be dropping off the pistons and rings on monday so we'll see what happens.

 

yeah, those are definitely not OEM type S pistons.

 

wut intake manifold r u guys running on these setups?

I was going to say the same thing. Those definitly arent OEM pistons

 

Be careful, you might stick you foot in your mouth without realizing it . . .

Just because you've never seen an OEM H22 Type S Piston with an aftermarket molly skirt before doesn't mean they don't exist.

Because I'm a nice guy, here's a pre-installation picture:



And a couple from the track after we blew it up:





I'll post the video of the dyno tuning if you ask nicely . . .

 

pretty please?

Please... lol. How high were you revving the car?

 

Lets see some more!

 

Dam what are you guys doing to theses motors... these are OEM pistons not racing pistons... I am using these pistons on my daily driver and I hope I don't have these type of problems because I don't wanna take the bus... and Please if your going to drag race your car on tha track and beat on it... please get forged pistons... I don't wanna see anymore pics it is just making me nervious I have spent a lot of my money on this build and I don't wanna see it go up in smoke....
