my question is will i be able to rev higher than 8grand after droping in itr cams ond valve spring. all i have is skunk2 cam gears itr cams on there way and some itr valve springs at the dealer waiting for me to pic up and a vafc. also if so will i be able to rev higher right away or do i have to tunned my vafc to rev higher? sorry but im a noob to this subject

 

dont u need to change ecu to do it ?
i dont know if VAFC can remove the rev limit

 

as long as the ECU allows you to rev that high you should be able to rev that high. however make sure you put those ITR valvesprings etc in before you rev that high, and dont rev that high unless the motor makes power up there, if the power starts to die off at around 7600 (just an example) dont rev to 8k. The VAFC will not take the revlimitor off.

 

I had the same question back then. I got CTR cams, new stock retainers, and portflow springs. Should be good enough for stock Type redline.

 

can you feel a big diffrence from changing your cams ? and are you making power up there around 8300

Yes you can feel a big difference depending on the tuning. A set of cams should always be tuned if you want to see great result out of your setup. The wilder the cams and the more tuning you need to see good gain.

The only cams that are somehow bolt on's, or where you can decent power without tuning, are the ctr type r cams although you can radically improve them with the addition of cam gears, hondata, kenji ecu, v-afc etc..
To get the most out of the cams you should also get the appropriate valve train

 

You can rev as high as you want...jus take the rev limiter out and dont brake your **** while rappn it out...those itr cams wont make power past around 8200 anyways.

 

well thanks evry one for responding now i have to stop talking about it And put these bad boys in.

 

You may want to consider ITR lma's just to be safe (assuming your ecu allows you to shift that high).

this is genius, pure ignorant genius. a stock type r redlines at 8400rpm, and will make power the whole way there, but not much PAST there.

special thanks, but NO THANKS, for your lack of input.

 

i just put some CTR cams, springs, and retainers in my girlfriends car and it pulls nicely all the way to 8700 no problem at all. B16 w/ headers and intake w/ chipped ls ecu.

 

mine made power til right over 8400, then i dropped off the gas. it seemed the power had started to peak, but it's nice to know they'd go a little higher.

 

itr cams can make power to 8600 rpms and with an itr valvetrain as well, and an ecu with higher rev capabilities you could rev to 9000 but wont make power that high, it will just help you be higher in the power band during the next gear...caution, this may cause valve floating over time...some people have gotten lucky and not had issues, some have after revving that high periodically

good point

my stock type r make power all the way to the rev limiter, so yes the R cams make juice up to 8600 and this is untuned!

 

so i would need to get a type r ecu because my gsr ecu wont let me rev that high.

 

i have a b16a2 (obd1) with a chipped p28 (skunk2) program and I rev to 9000rpm and make power all the way through......

 

Check out http://www.importreview.com look under the 1.8ltr dyno graphs. There are quite a few itr motors in there, and most of them seem to peak around 8k, and start dropping off before 8500. Stock itr redline may be 8400, but that doesn't mean it will always make power all the way there.

My 1.8 made 205whp with itr cams, but didn't make power past 8000.

Once you get them in go to the dyno, then you will know for sure where your shift points should be. Good Luck!

 

Your shift point might be after peak power. Vtec engines still make a good amount of power past peak. If you shift at peak you would actually accelerate slower due to making less power after the shifts.
