I have a EG6 with spoon sports header, ITR b-pipe, N1 backbox, 64mm throttle body and pipercross drop in air filter.
I still have stock ECU with 8300 rev limiter.

I'm thinking in install some 98 ITR camshafts (i choose this ones because it has less 3º on the intake duration then 00DC2/EK9 spec and as far has i know for the B16A2 engine is better less duration and more lift), my question is if i keep this rev limiter can i use stock valvetrain?

About the fuel should i have to reprogram ECU or can i simply use fuel pressure regulator from a ITR or is no need both of this?

Thanks for spending some time with an newbie.

Ps: This is a daily car and i´m not that guy who is always boucing at the rev limiter...
 
to get the full benifit from th cams you are looking to put in you would be best with a aftermarket valetrain and ecu remap but you can still run these cams without either . the just wont be as agressive as it would be if you got a aftermarket valvetrain and remap depending on what ecu you have at the moment :nice:

At the moment i have, like i said stock ECU (P30G), correct if i´m wrong but valvetrain i just need if i went for higher rev limiter right? And i really don't think this cams can produce much power after 8000/8200rpm so if i´m correct in this numbers is no point to rise the rev limiter.

Remaping ECU i agree with you, a good program can do some magic in an overall torque and hp numbers but i really didnt want that for now.

Maybe my question wasn't very clear, should ITR cams in B16A2 with my mods perform better than the standart ones with no valvetrain and ECU remap? It still reliable?

standard ecu's cant be remapped you will have to get a chipped one or a aftermarket one for example hondata, powerfc, aem

no i dont think you would want to set it much higher maybe 8500. they wont make power past that as these are similer to skunk2 stage 1's . i would stillgo for the valvetrain if it was me
 
u should fine with the standard valve train and u dont need to get a remap just get a ctr ecu which will be better suited to the cams
 
if you are going to be getting another ecu . i think you would be better getting an aftermarket one . you will then be able to use it for other mods . with the ctr ecu it will be fine with these but you wont be able to use it to tune ur care if you are looking at more mods after this

My ECU is already chipped BUT with the stock map and i have crome pro wideband o2 sensor if i want to reprogram the fuel tables that is not a problem but my question isn't that.
To 8500 i agree valvetrain needed but for stock EG6 rev limiter i don't think so.
I think you don't understand what i'm trying to ask...
 
yeh i would say make the limiter 8500 and new valvetrain. i think you would see the best results from that .

I beleave that ;)

For now i´m only focus in change the cams and see little top end gains.

Further i will change valvetrain, port and polish the head and raise the CR.

Thanks
 
your ecu will run obd1 witch means u can map it. its obd2 that u cant map it. you will be ok with your std v/springs would be better if u got the v/springs from the ITR. and i know that CTR cams make power up to 8400rpm so dont think the ITR cams would make much power after that.
 
Arite m8.. Yeah the cams will make abit more power with your mods - top end anyways. I wouldnt go wasting money on the CTR ECU as you would need to convert from 0bd1 to obd2 - then if you wanted to map for other mods you would have to convert back to your original obd1..

You'll need a ecu remap / new ecu.

You will need type r valve train , springs and retainers are a must have, since this camshafts are different from your oem.

I prefer to be safe just in case, I've seen how many motors get damaged because leaving for example stock type r valve train with toda camshafts (even they were not revved past 8700 RPM) .

Don't use a civic type r ecu, they suck lol. You can get something better for the same price (for example custom made chipped ecu from Phearable.net - Electronic Fuel Injection Tuning Solutions - Hondata, Neptune, Crome, Uberdata, Ectune, AEM, Honda Tuning, Widebands, Fuel Pumps, Intercoolers, Turbos, LS/VTEC, ECU Chipping, Chipped Ecus, P28 ).

I recommend using a fuel pressure regulator if you stock fuel pressure is not at 46-48 psi.

Revving with this cams at 8300, is ok, but you're wasting the camshafts potential, they can make power until 8700 - 8800 rpm.

Good luck

I really didn't know this cams can make power to that rpm...

Thanks everyone for the help.
 
Toda A and Skunk stg1 are a good upgrade for your B16A.
 
I meant tuner series. I think with pro series, you have to upgrade other parts.

aparently Toda A has more aggressive profiles than Skunk stg1

Not as much power as other aftermarket cams, but the power begins to "die" 8550 RPM + :nice:
 
iv been told the CTR cams are just the same as skunk stage 1. thats what iv got for my b16a2 but not got them in yet
 
hmm, profiles don't suggest that. but anyway, thats a good thing you got skunk stg1
