New Frank Build------Look

[c mak]

I just recently rebuilt my motor due to a couple cracked ringlands from boost. I decided to go back to all motor again.

Out with the old pistons----



In with the new pistons----Can someone guess what these are, its kind of a rare find by themselves!!!

Can you say no more dish and higher compression!!!

[c mak]

Here are some pics of my milled f22B also for even higher compression!!! Yea!!!

Gotta keep them JDM parts clean!!




Look at how much was taken off. This in on the sensor side of the head. Whats messed up, is that I can even have more taken off, prolly another 0.03, its amazing!!


Look at the Large valve size, especially on exhaust side!!

How did you just get F22B pistons?

Flatter, but you need some domed pistons.

Pic of it all back together again. I've only got around 340 miles on the breakin so far. It seems like there is alot more torque. I have not really gotten on it yet, just maybe 3/4 throttle. It seems like its gonna scream though, once I replace the oil after 500 miles.

My buddy, sleepycb7 had bought these pistons online from someone. Neither one of them knew what the hell they were! I traded sleepy some turbo parts for them and we later found out the jdm goodness that they are when we were putting them in my f22a block. It was funny, cuz he was like, "If I would have known what I had at the time, you would not have gotten them!" Oh well, at least they went to a good home!!

So basically you've turned a F22ax block into a JDM F22B complete motor. So minimal you're at 9.2 compression right there, but with a milled head, what are you at now? How much did you mill off?

I'm not fond of milling heads, it must have affected your timing belt settings some, how much since you've already put the motor together. I assumed you used a stock OEM F22ax headgasket?

Good deal though, another fresh motor on the road. Throw in any aftermarket camshafts in it? Any portwork on the head or modified intake system?

Ya, pretty much a jdm F22B now. Its an f22a block and crank, with F22B pistons, and head, and H23 manifold.

I got the head milled 0.03, used a new stock f22a headgasket and it did not affect the timingbelt setings really at all with the stock cams. I really don't know what compression I am running now? How can I figure it out really? Still running stock H23 manifold, head is stock with the mill, and stock F22B cams. I was going to try and throw like an F22B cam in and the other an H23 cam, but I decided against it and just threw in both the F22B cams. Do you think I could get any different results by putting an H23 cam in either the intake or exhaust? I know that they are similar, but have different lift and duration.

Cisco made an engine calculator. It uses Microsoft Excel. It is in one of the stickies at the top of this forum.

You don't need a calculator. If you only milled 0.003" off, you didn't change the compression ratio enough to matter. However, if you meant 0.030" then yes, you'll need a calculator.

Using the calculator and milling 0.030 I got 11.9:1. I think something is wrong there.

[preludeman92]

I got about 9.8:1 using the same calculator. don't know what you did.

[The G-Man]

I think the piston CC was jacked up.

[starchland]

are you using engine management?

Nice and loving the sig!

hahahaha, word.
