ANY BUYING/SELLING IN THIS FORUM WILL RESULT IN AN INSTANT BAN!

Read the rules: http://www.cb7tuner.com/vbb/showthread.php?t=43956

Myself, and the other mods have been very nice and lenient with the rules. We have been deleting threads, and giving out warnings. Some members didn't get the clue and re-posted over and over... Now ANY member buying or selling in this section will be banned... No IF's AND's or BUT's.

Beginner Forum Rules - EVERYBODY read! (old and new members alike!)

Beginners start here. Once you have 30 worthwhile posts (off topic doesn't count) you may post outside of the Beginner forums. Any "whoring" (posting simply to raise your post count) will return your count to 0, or result in a ban.

These are the rules. Read them. Live by them.

1) Absolutely NO flaming! "Flaming" is an outright attack on a member. ALL questions are encouraged to be asked here, no matter how basic. Members with over 30 posts will be subject to a ONE WEEK ban if caught flaming in this forum (and yes, moderators can read deleted posts). Members with under 30 posts will be subject to a ONE DAY ban.

2) Use appropriate language. Racial or sexual slurs will not be tolerated. A ban will be issued at the discretion of the cb7tuner.com staff.

3) No items may be sold in the Beginner forums. Any "for sale" threads will be deleted.

4) Temporarily banned members will be PERMANTLY banned if they are found posting on another account.

The rules can and will be added to. Any updates will be marked in the title.

The rules for the overall forum can be found here:

Read them. You will be expected to follow them.

    Probably not much at all. However, as you can use a hand file to take the edge off ever so slightly, it makes sense to do so while the head is off just for safe measure.

    No, the F23A rods are smaller in almost every dimension. They weigh around 117 grams less than an F22A rod does as well. The bearing width is narrower and the rod bearing journal is a smaller diameter. The F22A rod weighs 586g and the F23A rod weighs 469g. The F23A pistons are also lighter than the F22A with the F22A being 423.6g and the F23A at 406.9g. This is due to a much better casting process on an eight year newer design as logic would claim the F23A piston to be heavier because of the larger bore.

    For a boost build, I'd say the pistons are a moot point and should be swapped out anyway. Even the K20 pistons with an 86mm bore are better designed and capable of more boost than the OEM F/H-series pistons are.

      alright thanks ill have to keep all this in mind then. too bad those usdm f23a bottoms are more convenient with lower mileage.

      not sure if this was mentioned but somewhere in my research I read that these f23a1 rods are lighter and forged. Im sure its forged most likely for weight saving purposed but hey its worth a shot to ask. Got to verify this because too much false info floats around. Also read the f23 block has a bit more casting for more support of the sleeves in the lower area near crank. Not trying to turn this into f22 vs f23 but just trying to find out real info without buying f23 block and doing side by side comparison with f22a block.

        The F23A bottom end is better from a structural standpoint with the exception of the rods. The rod journals have a smaller diameter and are narrower as well. This isn't a concern unless you're trying to rev it to the moon. The main difference you'll notice is the strength of the main girdle. It's a much more beefy design that connects to more points on the bottom of the block for rigidity.
