The Camshaft Mega-Thread!

[My2fast240sx]

Does the mix and match with cams and diff make a difference?

[blackieblack]

indirectly it does.............it all has to do with what your targeting your car at. drift. drag. or autox or just driving around. cams are really heavily tied into horsepower and how u want the motor to respond. evrything ties into your target. evrything suports everything else. suspension tuning, etc......

what's a good cam setup for an s14 sr20 with stock turbo and intake/exhaust manifolds? 254/254 or 256/264? will a p&p do much? what exactly does the 3 angle valve job do? what will my power look like with a p&p, 256/264 or 256/256, and 3 angle valve job? with a ecu reflash, and provided injectors/maf upgraded

256 Cams works best with turbos that reach full boost in the 3krpm area. 264 cams work best with turbos reaching full boost in the low - mid 4krpm range. 272 cams work best with turbos reaching full boost from late 4krpm - high 5krpm. 280 Cams work best with turbos reaching full boost anywhere from 6krpm+.

I think if you run staggered cam setups, youd have to play around with cam timing as well to get the perfect setup. I dont think its worth it personally.

I plan to run the 264 BC cams on my T25 turbo until I can afford to upgrade to a T28. But I was wondering for your input prodigy. Thanks

[idahotuner]

i have 264 cams right now, but i am upgrading to the gt2871 .64. and i not drivign the car unti lthe new turbo is on. so the motor is sittign there with cams lol

[DrifterProdigy85]

I used to run HKS 264 Step 1 cams with the stock T25. The cams will change the powerband a little with the turbo. Stock cams and T25, its like instant power as soon as boost is touched. With the 264 cams, you will have your boost then the power will kick in hardest around 4krpm. From when i had them and the T25, i say there was a gain of about 10-15tq around 4krpm but would still drop off at higher rpm cause the turbo is too small. Currently im running 270 cams with the 2871R .86 turbo. It has a similar feel to it. Boost hits 18psi around 4400rpm but the power doesnt hit hardest till 5krpm. As long as rpm's are above 3500rpm the setup is very responsive. Its one of those feelings you need to drive the car to understand.

[RCCC_DRiFteR]

Ok, I plan to eventually swap to a T28. I know t prolly not the best turbo to feel the most power, but it's alot more reasonable of upgrading to and getting ahold of one for me. Prodigy, as for drifting did the 264 cams through you off in the middle of the drift from the full power??

[DrifterProdigy85]

lol. i dont do much drifting at all. just a dumb name i came up with a long time ago. i really want to change it to KB240SR which is what i go by on all other forums. but from when i do slide from time to time, they didnt hurt whatsoever. when drifting, the powerband is almost always over 4krpm so the 264 cams are perfect for that. theres quite a few pro drifters that run 272 cams and work out well. they just clutch kick more often to keep higher rpm.

[RCCC_DRiFteR]

Ok, that what i was pretty sure of. The powerband at around 4K, and most drifts your around or already 4K anyways. Thanks Drift

[idahotuner]

how many people really drift there cars that are on here.

whe n istarted my build i was liek i am going to drift. but not now
drifting is expensive.


so what cams you going with then^

[RCCC_DRiFteR]

I drift my car. But I do feel like alot pf ppl here don't drift and just build they're 240's to go fast in a street line. But I was planning on getting the BC 264 cams, BC valves springs, and BC retainers

[idahotuner]

cool. i got the springs and cams. i havent fired my engine up yet since the install yet. casue i am doing everything at once. lol but i am building a mean streat machine

[DrifterProdigy85]

Dont get me wrong. I used to drift but found it to be pointless in my area cause the nearest events are about 2 hours away and the streets are just stupid to do it in. So i changed my car setup over to be all out fast.

[idahotuner]

yea this is my plan as well. the nearest track si like and hour and half away.

so i just want one mean street machine

[RCCC_DRiFteR]

cool. i got the springs and cams. i havent fired my engine up yet since the install yet. casue i am doing everything at once. lol but i am building a mean streat machine

That's how I plan to do it. i wanna get everything together when i start building my motor. I don't wanna half build the motor and still be waiting for my metal head gasket. But I would rather see a 240 built to go fast rather than a honda. They sicken me

[idahotuner]

yea i buy a new part every month and install it during the month and at the end of the month i buy another part. that is how i am putting it together

[RCCC_DRiFteR]

yea i buy a new part every month and install it during the month and at the end of the month i buy another part. that is how i am putting it together

I'm gettin quite a few thing for xmas and then I'm gonna start workin again once I get back to Sac from Hawaii. SHould be entirely done mid spring - mid summer

[idahotuner]

yea i am getting the most parts for my car this month to. it is sweet. car should be running by march. and should be allmost completly done at the end of may.

[RCCC_DRiFteR]

That's dope, I almost have an anxiety attack just thinking about all the work and things I need to get though

[idahotuner]

yea
the first time i added up every thing i was going to need. i was like HOLY SHlT! 9k+ that is crazy. but i think over all it will be worth it.

[RCCC_DRiFteR]

Yeah it can be nerve whracking just thinking about it all. But it's not $9K all spent at once, but over a extended period of time which makes it alot more possible

[idahotuner]

yea. i have been buying stuff for my car and paying it off since july. well i paid it off a while back now. but yea. when you do it over a period of time it deffently doesnt seem as bad. i am half way done with my build. it is pretty much just messing around with small stuff after i get my motor back in. and we need to finish paint. but this is the cam shaft thread lets keep it on topic. you can check out my build thread in my sig.

[RCCC_DRiFteR]

LoL yeah. I heard the BC retainers are grabge though!?!?

[idahotuner]

ilovemy240sx recomened them and he knows his stuff. and i have heard nothing but good stuff abotu them.

[RCCC_DRiFteR]

It was my friend who was sayin that somethin bout how the retainers are made of aluminum and they crack or somethin. I was a lil confused cause he was tellin me over the phone. But he knows his stuff. Here's his car:

[idahotuner]

the retainers are titamium i thought, not aluminum. and the springs are a good upgrade over stock no matter what you do.

[DrifterProdigy85]

BC Spings are awesome. There just as stiff as Farrerea i believe. I use them in my car with solid lifters and rev to 8500rpm no problem.

[RCCC_DRiFteR]

LoL now i look back. I meant titanium not aluminum. But I didnt say the BC springs were bad, they're great. But it was the retainers that weren't so good. What brand would you recommend for rocker arm stoppers??

[idahotuner]

i think greddy makes some but thos are the only ones i have seen
