Be aware that revving higher than stock puts a strain on the bottom end as well. I wouldn't spend money modifying the head just to risk putting a piston through it when a rod gives out!
Upgrading the valvetrain is important for high revs in the top end, and upgrading the rods and bearings (well, replacing the bearings) is important in the bottom end.
The H23 ECU (P14, I think?) should have a stock limiter. Even taking it to that isn't really a smart idea in stock form... especially given the age of the motor. In stock form, the motor won't make any more power higher than the stock limit anyway, so don't even worry about that. Headwork and cams, along with proper intake, exhaust, and tuning, will allow it to make power in a higher range... and then the upgrades I mentioned earlier will be necessary.

well the only reason i ask is becuase i have a Apexi SAFC2 and i can mess with the rev limiter and such......i dont know all the details of the cars specs becuase prev. owner is impossible ot reach....but i do know that i can change my RPM limit, and i was simply asking what it would be best for. Right now the car is limited to 6800 RPMs and shifts at about 6500 if in D4 and whomping on it. The car has been dyno tuned and tested by a 2 shops, RACE WORKS and SCP. The tranny has been tuned to say the least, im not sure if there was minor work done to it as well.
*EDIT* Ok , i really have had this question for a while and i want to know the answer ........ is the H23A a good motor..... i not only have not seen many of them swapped into our cars, but are they a weak engine???? i am just asking if i should get a H22 and then T it....i want to T this engine.....please be honestLast edited by Paintba113r; 06-10-2007, 10:47 PM.

The H23 is a good motor... but has the same FRM sleeves as the H22. The lower compression makes it a safer motor to turbo in stock form, but it still may not last THAT long (boosting stock honda motors is never a good idea, IMO)
The H23 is a very capable motor, and with turbo, it'll be great. Just do it right, and spend the money for good parts and tuning. If you halfass the work, you'll get crappy results.
