At PSI//HP do the ring lands (which are from what ive heard, the weakest of the internal h23) become an issue? I have read numerous threads saying that you dont have to worry about it all the way up to about 350 horse, but i guess im not really sure. Looking for somone with maybe some first hand experience

 

I've been following h23 builds allot and most of the them seem to go from 10-14psi. It's all on how much borrowed time you earned from your ringlands. Those rings lands will go way before 350whp.

thats not true at all.....people have gone past the 400whp mark on stock guts, even touching the 500whp mark a couple years ago.

The problem with CAST pistons is inconsistency in the process...One person runs 300+ just fine and another runs 225whp and they break. Its really hit or miss with them......Fast-Cheap-Reliable=Pick 2!
I am in the firm belief that anything more than bolt ons in a Prelude is borrowed time. Everytime I race my Prelude I know very well it could be the last time I do.
I am also above the norm with power and abuse.......
What I tell most people craving Nitrous, if you can't afford a New motor, you have no business spraying......Same goes with Boosting a stock gut H22/H23. You may have tons of fun for years on 7-9psi or you could ruin your engine 1st time out because you happen to have a hairline fracture in a piston already......From manufacturer flaw or an old abused motor.
Ive never been a fan of boosting stock motors.......

 

timing, heat and preignition kill ring landings. the people runing high horsepower were tuned by talented individuals who know how much timing is to much for brittle cast pistons.

like said above one set of pistons might be strong as all hell and the other you can sneeze and the break.

because the h23 has lower compression it will take alittle better to boost, so approaching 12-14 without an excellent tune will result in disaster.

also remember psi is not the same from turbo to turbo, you need to look at flow. boosting an h23 around town on 12 psi from a t25 mitsu turbo is nothing , where as an engine with a 60-1 or t67 making 12 psi will produce much more power and put alot more stress on the internals.

I didn't think excellent tuner and MN was possible....
Has he tuned alot of turbo Hondas??? that would be my 1st requirement....

http://www.myspace.com/10penny His myspace pretty much speaks for itself

Consumate tuning.

i didn't mean to be harsh, I have just grown to be synical about all these good "tunners". I have just seen some pretty crazy stuff pass as a "safe map" on some fully tuned motors. Im no expert either, but tuning each motor to its potential really takes understanding. Your guy might be great, and if so good for your motor it will last much longer than those other "tuned" boosted H's

 

i've got plenty of trophies from playing soccer doesnt mean i can tune a motor. when i selected a tuner i looked around for about 6 months before i decided on which one. if you know he is a great tuner then go for it, but tuning a boosted stock block h is not a plug and play affair.

Soccer trophies, and first place trophies from battle of the imports are slightly different. But im gonna stop defending him. His work does that for him.

 

If they aren't Trophies for Tuning.....I don't think they mean much.
good Luck though...

Thanks for your concern but i think his tuner has adequate experience and knowledge.

Zach i sent you a message about turbo selection.
