i'm looking into getting myself a set of these camshafts but I was wondering if i need the itr valve springs along with it? i'm getting mixed opinions as far as old posts. Some people have good experiences without and one recent incident with a member blowing his motor because of his stock valve springs. Also, i visited a shop today and he recommended me getting valve springs along with it.

The cost of the valve springs isn't the problem, the cost of installation on the other hand is. I got quoted 100 for the cams install and 200 for the valve springs install.

if you are keeping stock redline, no valvetrain needed.

 

thats what i always thought too anyone else?

 

yeah most people will say you wont need a valvetrain upgrade with itr or ctr cams.

i just got my itr cams and i will be getting new springs and retainers just to be safe and i will prolly raise my redline a littlebit.

also i might as well install everything at once so i dont have to worry about it later.

 

yeah, stock valvetrain should be fine, btw, installing cams are very easy to do yourself, just buy a haynes/helms for further info and torquing specs, it'll save your the 100 bucks minus the manual.

yeah i've been thinking about installing it myself but I don't want to **** anything up is a valve adjustment needed?

I've been running ITR cams for a while now on my stock gsr valvetrain, stock redline. no probs yet. Though it wouldn't be a bad thing to upgrade the valvetrain just to be safe.

 

running type r valves intake and exhaust, type r springs, and type are retainers with civic r cams, car screams to 9k...I would upgrade the valvetrain if you are planning to raise your red line and to get full use of your cams, remember civic r cams are a little more aggresive then the ITR cams

Would ef-1 valve springs and retainers be overkill? If I wanted to rev to 8.4k would the better route to go be just itr valve springs? Or do I need the retainers also. This is on a gsr w/ctr cams.

 

It really depends on how much your car is worth to you.

IE

The DOT 6 fluid I spent mad LOOT on yO!

I'll never boil my brake fluid on the street but it's good to know I could drive like that say if I was being pursued by the cops through the mountains of death valley at high noon in July.

Taking it back to pre school

"it's better to be safe than sorry"

words to live by.

 

I'd go ahead and spend the money and get some ITR valvesprings. Few guys here kept the motor stock and never went past redline, and they dropped some valves.

Better safe then sorry.

Hell, I rock Skunk2 valvetrain on my GSR cams.

do you happen to know their usernames? i'd like to look them up if possible.

 

try searching for "itr valve" in the archived content and I'm sure you'll get some hits.

I know for sure Riceball777 dropped two valves running CTRs on a stock valve train. The CTRs are bearly more agressive than the ITRs.

There are a few other people, but you'll have to dig. They aren't Integra owners. I think one guy was a Del Sol VTEC owner. Not sure. I'll try to find the thread.


I mean really, valve springs and retainers are not that expensive now adays. You can get Sunk2 and EF1 for a damn good price. I'd like to even change mine out to the EF1 valvetrain now. Rocket holds it down on some quality fitting products.

the price of the valve springs isn't the problem but the installation cost is. The local shop wanted 200 for valve springs install. I'm not really mechanically inclined and i'd much rather have a reputable shop work on my car. The valve springs cost along with installation would run probably 300 altogether along with the 400+ for the cams and install. Doing the installation myself would save alot of money but i just dont have the time and means.

 

i would change the valave springs and retainers while ur at it. its really easy to do with the snap on valve spring compressor tool. only reason i say to change them is beacuse, the cams are out and its the perfect time to do it. itr cams pull great all the way to 8400-8600rpm. if you plan to keep the stock gsr ecu and never raise ur redline from 8100 then its really up to you if you have the cash to spend on the valve train.

i installed a set of Skunk2 stage 1's along with a Portflow valvetrain (titainium retainers, Portflow inners and ITR outters). really easy.. made very good power gains.. and his valve train is capable of revving over 9000rpm.

my opinion is to change it. but its NOT needed if u keeping stock redline. anythign over stock valve train, u better get somthing different

 

thanks for the help guys, I don't plan on raising my redline or revving pass my stock redline. I see you're from the bay area downey, do you know anyone who could install the parts for a good price?. I got my price quotes from blacktrax and they told me to install valve springs they usually take off the head so the charge is more expensive.

 

i can do it for you if you want. ive done it before a few times, so i know what im doing. are you going to change the valve springs and retainers or use the stock stuff. if u are NEVER going to raise ur redline.. theres no point in changing them

yeah thats what I thought too but hearing a couple of bent valve stories kinda worries me. If you could hook it up with a cam install that would be great man. I plan on getting the cams within a month.

Are the retainers necessary? I'm thinking maybe I'll just go ef-1 valve springs and retainers and get Jeff @ Hybridautomotive to do the install for me.

yeah but you can bend your valves by misshifting too. It is a pretty safe bet that ITR cams with stock redline and stock valvesprings will not cause any more damage then the stock cams would in the same situation, especially if your dropping them in a B18C1...hehe. Upgrading the valvetrain is way overkill if you are keeping the stock redline.

 

thanks guys, this way i could use the 300 from the valve springs+install towards a vafc and tuning.

Another question for you guys: do you think i should get cam gear's along with the itr camshafts? Will the adjustable cam gears like skunk2 help me out more then the vafc on the dyno?

Definatly go with ef-1. Decent price and that is a quality product and Yes Retainers are necessary. The OE retainers are horrible. You wouldn't want to half *** any sort of important job, would you?
