not reallt sure what you mean. do you want to redline the car? you cant swap ecus there diferent systems. yours has dbw. also redlining is bad for the motor and pointless because your just going to loose power in the higher rpms

ok i might of assumed id lose power but im going turbo so if i rev it out it will cut me down bog out cause of the rev limiter the 05 forenza can bounce the rev

i know like i said before its a different system you have DBW. the o5 has a rev limiter also.
your also going to have to beef up the trans and clutch or youll blow it putting any kind of real boost through it

as a note, when you red line your increasing your you chances of dropping a valve. The engine's shafts (crank and camshafts) are rotating too fast, the valves begin to float(they don't fully close or open) and when you quickly drop the rpms, like when shifting, the valves smack the hell out of the head and can break. I know you don't care but I feel better having said it than to hear a few weeks/months from now that your engine is done.

When you redline does that mean passing the 6.5 rpm or going to 6.5 rpm is redlining?

I passed someone a couple months ago and it 6.5rpm then the rpm fell to something ( I don't remember). Is that bad for the engine?

when the needle goes into the red part on the gauge, hense, redlining. it fell because it changed gears. if you hold a gear to long, really only in a manual, it can go up into this area. bad for most cars, some can do it without problems but it needs some modification. cars have a rev limiter in them so basically power is cut when you reach this area to prevent damage. in an auto it will just shift gears at an apointed rpm

If you have a manual and hold it at the redline you can cause damage, if you hit redline every once and a while you should be ok. But I recommend that you not redline it if at all possible. I by no means am perfect and have redlined mine a few times. But the rev limiter on our cars is pretty good about keeping the engine from over revving.
Also like i said above, the valves float at redline, so they do not fully open or close causing incomplete combustion. And as about everyone knows with incomplete combustion comes power loss and lower fuel economy. and although you may get away with it for a long time it only takes one weak part in the engine and you can say goodbye to that engine.
So to sum it all up holding it in/at redline for a long time or continuously shifting after holding it in redline can cause a good amount of damage and does not give you more horsepower or torque.

Ah ok. You guys put sense into me. I have an auto so I'm not worried about redlining. Since I acclerate that hard. Whew.
