The Camshaft Mega-Thread!

[norcals14]

here's my build so far:

.20 overborecp pistonspnp'd headgreddy springscrower retainers3 angle valve jobjgy light weight flywheel

and im getting:740cc injectorst3/t4.. unsure of a/r and trim (would like advice)fmic

so what kind of cams should i get? im thinking 264 step 2's but i'd like a second opinion... what brands?

thanks in advance guys!

[Fenvy]

I am no expert but ever thought about

264 intake and 272 exhaust?

[vutony]

first of all, get rid of greddy springs and get peaks performance made by comp, JWT S3 or S4 cams would be nice

uhh... theres nothing wrong with greddy springs. so what if comp is a bit stiffer? greddy would be just fine

as for cams..... everyone thats runnings HKS seem to like it. and depending on your size turbo and how much power you're planning to make youd go for step1 or 2s... I personally run JWT S4 and i love em... very nice but pricey

[norcals14]

thanks for the advice so far what do you guys think about the 264 int 272 exh idea? im a newb when it comes to cams but i think i will go with hks...

[meangreens14]

im in no way trying to thread jack, but this would most likely be a place to ask...is it neccissary to get cams if you have nothing else done to the internals of an sr engine? i asked my buddy at rmj motorsports, and i was given an answer that was along those lines. whats ur guys' take on this?

but for norcals14..iv'e HEARD that 264 intake and 272 exhaust is a good setup to run.

If I understand you correctly, I think you want to ask how much power will the stock bottom end take? With that power level, do I really need cams?

The answer to Q1 is: Enough for you to add cams...

Of course no one has the magic value but if you are making over 320 HP or so you could definitely benefit from adding cams. And yes, the stock bottom end can take that much power.

[deCksy]

oooops, it was hks thats similar to stock

yeah thats what i was thinking that you were thinking... sall good! but yeah stay away from HKS springs! who wants expensive springs that are basically stock spring?! say no to soft!

i would say it depends on your snail. if you have a big smail and want more air to be pushing thru then cams will do wonders! but its NOT necessary for cams... its just a good upgrade

[norcals14]

so is there anyone who actually runs 264 and 272?? not to take away from what anyone has heard, i just want to hear from someone with the setup...

[norcals14]

ttt

[norcals14]

sounds good thanks...

[DrifterProdigy85]

what kind of powerband are you looking for? with my 2871R .86, peak torque is 5krpm and drives hard to redline. Best cams for this powerband is a straight 272 setup. but if your turbo gives good torque in the 4krpm area then id go the 264 route.

[partymonster 975]

264/264, or 272/272 Thats what idk get but I never really look into too aggressive cams.

[I ask good questions]

Has anyone used the street/strip cams yet? They have the same duration but a higher lift than the HKS step 1 cams. It says that OEM spring is ok to use but still recommends upgrading to better springs and retainers? Is it really necessary to do so? If i raised my rev limiter i would mostly likely only raise it to 8000 rpm. I plan on getting some RAS also. I assume that they are great quality because of the name on them. Does anyone have input on them? They seem like a great alternative to the overpriced HKS, Toda, and Tomei cams.

[es-14]

yea im interested in hearing what people have to say about those cams too. i was checking them out last night on enjuku. the price was very attractive but if they arent worth the buck hks will be my first choice.

[norcals14]

thanks for all the help guys.. i think im going to go with 272/272 step 2's but what benefits would be seen from running a 264/272 setup?? better spooling without such an aggressive intake??

[drupie51013]

i have set of the brian crowers 264's but i havent put them in yet until im done gathering all my "performance" parts and do it all at once. but the cams look good the i picked up a set for 200 brand new from a local. im going to put springs and retainers even though they say the stock springs are "ok" to use but since everything is going to be apart might as well.

[Mouse6933]

hey are you using the bc springs and retainers also, because i was lookin in to this setup, with the ras. studs, and new hg, i cant wait till you get them in to get sdome feedback... Thanks

hello???

[Dugi]

i'm also wanting to upgrade cams. i'm going with brian crower cams 264/264. nothing really big. but what I want to know is are adjustable camgears a must?? or can the cams be put to zero like oem??

[Dugi]

I'm also going with these cams. ordering this week if everything goes well. i'll be changing my springs and retainers also. but got one question. are adjustable camgears also a must to change?? i've heard that when upgranding cams adjustables are a must. or is this false??

No and you should do some HW before gettin BC

[95silvia14]

so im looking into doing some upgrades to the valvetrain on my sr and was looking into getting a set of cams but i dont know which ones would be good for my set up; im looking into either tomei type r, or hks step 3 cams with a 272 duration, ive searched and relly havent found any info to help with my current setup, switching from the stock t25 to a gt3076r. at about 30 psi with a a/r of .84. any help or other suggestions on cams please help me out with your opinions.

ok if you want the end all springs my man then you need to check out supertech springs..bit pricey but in the end you get what you pay for...all the springs are load tested to make sure they are all matching in the box and you can get different rates..all up to you..if you dont want valve float i would suggest not getting HKS or Greddy..not bashing them but if you want piece of mind go with a set of springs you wont have to worry about..if you are going to be a rev whore i woudl also strongly suggest setting yourself up with a set of solid lifters..the factory hydraulic lash adjusters dont really like going much past the stock rev range..and depending on your cam selection ive seen many SR's clicking off 10k rpm..with a proper head setup

[norcals14]

woah... i was like i never subscribed to a cam mega thread!! lol! well go me for starting an official mega thread!! anyways i have a question... i hear alot of people running 25+psi on their setups and call me a newb but coming from honda's and rotary's that sounds nuts... i assume that these ppl have stock bottom ends.. so what kind of head work is needed for that kind of boost??? everything and a fat gasket? or would my setup be fine??

my setup:.20 overbore w/ cp pistonsbrand new head w/ 3 angle valve job and a street port/polishgreddy springscrower retainers

getting:cams most likely hks 272 step 2'ssolid lifterscam gearsand probably jwt or bc valves...

oh and most importantly a gt35r or a turbonetics 60 trim turbo

[norcals14]

thats what i said... again lamest mega thread ever!!!! someone tell us the benefits of 264/272 setup!!!
