Build Engine or wait for it to blow and get JDM H22
My brother is taking an engine class and he needs a project so I was thinking of having him build my motor with high compression forged pistons forged rods and new cams. Or should I wait for my H23 to blow and get a JDM H22 swap?

Step 1. Let your brother build your engine

Step 3. Get JDM H22 swap
Step 4. Keep brother the hell away from this engine
why would he want his brother to screw up and ruin his engine?
also, j_t_heilbrun what makes you think your engine is going to blow anyway? people drive their preludes for hundreds of thousands of miles with the proper maintenance, on the original engine. see the "how many miles does your stock engine have?" thread for proof.
sorry, i'm just getting tired of seeing the "wait for h23 to die or go jdm h22?" thread over and over again, as if the motor has this short lifespan or something. i guess either a lot of people on here like to abuse their engines or they bought a ****ed up car from someone else without realizing it.

I was not implying the H23 has a short lifespan, I bought my car because I know it'll last me damn near as long as I want. I was just saying might as well wait till you actually NEED a new engine to do the swap, but his bro trying to build it up might speed along that process if he accidently screws up somewhere. I'd love to hear that he did a great job and the engine is better than ever though.
Don't use forged pistons..... Your motor will be toast... I suggest you boys read up BIG TIME about rebuliding engines before you even think of attempting this.

Because H23 and H22A blocks use the FRM coating walls... Forged pistons are made out of an aluminum alloy, there for aluminum and aliminum wearing against each other causes alot of friction, there for leaving scored cyclinder walls and severe gauges under some circumstances. If you want to use forged pistons you must resleeve your block, but then you are weakening the block if you go with cast iron sleeves.
I thought it would have been pretty clear why he needs to read up alot, before he goes through a rebuild. I have spent the past 2 months doing research on everything for my rebuild. And I've come to the conclusion, half the people I've talked to dont' know squat. I call performance shops, places that sell jdm parts, honda mechanics even, and they don't know jack about rebuilds, or the H22A motor even. Most shops and Honda Repair shops, buy entire pieces like heads or blocks and just bolt them on, they rarely deal with internals, because the workings of the Honda long blocks are so fine tuned they are hard to work with.
