ctr cams in gsr. new valve springs??
i cant find crap on this! i just bought ctr intake cam and itr exhuast cam for my 94 gsr motor. now i heard u dont need to change the valve springs just keep to normal redline for gsr and u wont float a valve. which sounds right to me because its the same exact spec as skunk2 stage 1 just a longer duration and u dont need aftermarket springs for that. SO today i bought Toda valve springs to be on the safe side. The reason i bought these is because i have a 9800rpm redline on my jun chipped ecu. so if this was true and didnt change my springs, and mis shifted, id be screwed right? andyway really this is for my own knowledge since i already bought the springs
...
i didnt really want a red line that damn high! couuld the gsr handle that with toda springs, ctr cams? i dont even think it makes power up there does it? i mean im gonna dyno later so i can see where power cuts off. but since i have the jun chip i figured well the cams might make power alot higher now. im just looking for info!

so since i have toda valve springs, i can use my stock gsr retainers...so with this setup....ctr intake, itr exhaust, toda springs, i can take it to 9k? the motor wouldnt let go would it? i mean the gsr i figure can spin on stock internals and rod bolts to 9k right?
The motor won't let go but you won't be making power up that high anyway so there's no need to rev like that. 8400 rpm max would be more than enough rpm with those cams. Stock valve springs would have been fine with those stock type cams, Toda will work but aren't required.
ctr cams pull real high i know my itr cams make power till 8800 then start to fall off so ur cams will pull even higher b/c ctr put it on a dyno to see for real if u only take ur motor to 9000 or 9200 to see where power falls off u will be fine with toda springs ur stock retainers will take a dump after 9200 but ur motors fine till that the only ther thing is worring bout spinning a bearing

Holy crap man, learn how to type sentences! If those cams don't make power that high in a CTR or ITR, what makes you think they're going to make power that high in a mild GSR with lower compression?
im thinking about canceling the order on the springs. getting an msd box so i can set the spark limiter. this way i can set it to where at about lets say...8500 rpms the spark stops so i cant rev past it?? that way if i miss im not gonna throw a rod of float a valve. leave the stock gsr springs. i think this sounds good. and when i dyno it and it makes power to say, 8200 then i'll set the spark limiter to 8300. sound like a plan or stick with the toda???
cause i mean 360?? i can buy a nice msd set-up for 150 of full set-up for 300! what do you guys think? i have all these people telling me its cool its fine no prob. i dont see why not.

Aren't the toda springs made for more aggressive cams, and therefore stiffer, and harder to compress causing drag on the engine? I don't like mismatched parts ideas.
why don't you just get some itr intake dual springs, switch your gsr intakes to the exhaust side and it'll be done right with no worries. When you take it to get tuned, they can put your custom rev limiter on your custom chip wherever you want. you are obd1 i assume?
there's no reson for these cams to make usable power past the stock itr redline, unless you've got lots more junk done to the engine.

lol...i have some good info showing me its all good with stock springs. wont be going past 8500 at all. i am buying the msdl kitso i cn set a spark rev limiter plus better ignition! but i WILL be doing ITR valve train down the road but as of now, i think it will be just fine. thanks for the help fella's!
did your info come from a reliable source that did before and after measurments on the entire valve train assembly to check for wear? There's so many people out there saying that stock gsr springs will be fine simply because their engines havn't blown up in xxx miles of driving.
Not saying stock springs won't be fine, but 8500rpms?...Honda didn't think stock gsr springs were fine on the itr with your specs. But its your engine tho and what do i know.
Also, if you get your engine tuned, that msd ignition will be a waste of money, that crap is for FI.

how much do you want for the itr valve springs? im not gonna spend like 250 bucks on used itr stuff when i can buy crower for that price. give me a decent price and i just might...
that crap is for Fi? lol fuel injection comes to mind! anyway why would it be a bad idea? i talked to a few people with gsr valve springs and they just have the stock redline at 8200 and they are just fine. the lift isnt some gigantic ammount. and like i said, if its not required for skunk2 stage 1's why would it be required for ctr? they are the same exact lift. the only difference is the ctr has a little longer duration. ok how much does itr valvetrain usually run...

contact Bert-o on here...if hes around....hes an OEM acura parts dealer out of FL with good prices....i think its a little under 200 for a set of ITR springs....or inlinefour.com...or acuraautomotiveparts.org
When I was using CTR cams in my old GSR (bumped compression and bolt ons), I just doubled up on the exhaust valve springs. It was cheap, and held up great for about 3 years before I changed my set up. On the dyno, it made power to 8400rpm, then fell off.

I was using both cams. Doubled exhaust valve springs, that's all that was needed

Gain power with different valve springs???
