The Camshaft Mega-Thread!

[DrifterProdigy85]

Matt Back Vass that used to be on Fresh Alloy used them on a car. He ended up breaking a spring. He stands by Peak Porformance valvetrain now.

I just bought Brian Crower 264 Street/Strip cams to replace my HKS 264 Step 1 setup. Ill post the results in a few weeks. Ill try and get a 14psi dyno run on both cams to see the differences.

[blackieblack]

thats awesome. your like using your car as guinea pig. lets see that BC magic aforementioned. thanks for keeping this thread going.

[DrifterProdigy85]

By specs they should out do the HKS 264 Step 2's and Tomei 260's. The higher lift should allow torque to be held longer into the powerband which makes for more HP in the end. But we will see. Im also gonna run stock springs with them. Only revving to 7000-7500rpm and ive been told by BC and MA Motorsports its alright. So we will see about that too.

[blackieblack]

thanks for all the work. its much needed and appreciated. at least by me.

why run stock springs and retainers? you can get the BC spring/retainer kit from enjuku $229.99 minus the nico discount.

[DrifterProdigy85]

You forget the work involved. I want something that can be dropped in for the meantime. Ill be building my spare head soon which will have all BC valvetrain, P&P, and 3 Angle Valve Job.

[blackieblack]

as far as head work are you going all BC?

[DrifterProdigy85]

BC Cams, Valvesprings, and Retainers. Keeping stock valves. P&P and Valve Job will be done by a local Performance Shop. Theyve been in buisiness for 40+ years so i trust them with the work. HG will be Apexi or Tomei.

[blackieblack]

whats a far price for p&p and 3 angle valve job?

[DrifterProdigy85]

Complete P&P is around $600 and 3 Angle Job is $150-$200. Could just get a minor P&P done of cleaning the casting and polish which is around $150. Thats the prices i got.

[blackieblack]

now that i think about it. bc cams seem ideal for more mid to high horse power making.

[blackieblack]

BC cams sold out on their homesite. all the step ones are sold for the sr. now ive heard good things and bad things about the BC cams. actually i heard that someone heard bad things about the bc cams. cause i myslf have heard good things. anyone else care to share anyone rumors?bc is pretty damn good with othermotors. good honda cams. i havent heard any complaints from those ...............................other motor lovers.

[DrifterProdigy85]

I put my BC 264 cams in on Tuesday. Waiting to dyno but they are smoother than my HKS 264 Step 1 cams were and give crazy pull in the top end. So far, no bad effects using the stock springs with the cams. Oh yea, the last order they had went to MA Motorsports where i got mine just in time for there shortage. Good luck finding more for a little while.

[blackieblack]

sweet. im gonna stop this procrastinating and buy em!!

[DrifterProdigy85]

Thats the spirit.

I dont think any name brand cams need adjustable cam gears. Sure there will be some gains with them but not worth the money in dyno time for it.

I have to disagree with that statement. Im currently running a T3-T04s 60-1 turbo on my car, in comparison its just bigger than a GT30r, with stock cams i had no problem pulling off low speed drifts. Since then ive upgraded my cams to Toda n2 264s and it shifted my powerband up too high to be able to get good power below 5k!! So now im using Fidanza camgears to bring the powerband back down to have more useable power at my disposal! With camgears u can really tune the way u make power u can make the powerband broad or make it short and peaky. Its a good investment if u want to do more than just 1 form of racing.......

[DrifterProdigy85]

Post the before and after dyno please. Also how much has it cost in dyno time to adjust them. Pulling the valve cover on and off gets time consuming if your paying by the hour for dyno time.

[zenkisilvia]

It only cost me $100 to tune on the dyno becuase of the fact that its pretty simple to tune a SAFC and i played around with the cam gears to find the right powerband that worked for me before i got it tuned, so that kept the dyno time to a minimal ... I cant tell how much gain tuning the camgears actually made because i upgraded several things this time around. But if u look at the big picture what good is putting cams in if u only have 2000rpm of useable power? The cam gears allow u to take full advantage of the cams that u run....I ran my cams at tdc and it didnt start pulling hard till 5800rpm then i advanced the intake cam 4 deg and the power moved down to about 5000 and so on. But thats why they call what we do tuning, and thats the beauty of having adjustable things like camgears so everybody's car dont run exactly the same..

[ca18det_boy]

I'm running the BC 272 cams with their springs and retainers. .20 over. The untuned powerband is kinda wierd at first, but I start building boost hella faster and it just seems to keep on pulling. Not a crazy idle with it being untuned, but so far I'm pleased.

What size turbo r u running?T3-T04e

[ca18det_boy]

T04B90 V1/V2 for now, I just got my hands on an HKS turbo kit that will be going on next week. So this turbo kit is up for sale.

[mcdade240sx]

Just bought a 96 240sx w/ a s13 sr. Was wondering if you could help give me some tips. Have a lsd also. Will a z32 diff fit in the old diff's housing? That way I don't have to replace the flanges. Also which turbo is best for 500 whp? Is factory bottom okay for 500whp? What about the cams? Please help. I appreciate it, thank you.

Yeah the z32 diff will work inside of your housing but i heard its not fun at all doing it i would recommend a professional install it. As for a turbo that will make 500hp the highest flowing turbo that garrett makes that supports the factory style T25 flange is the gt3071r with the .86Ar turbine housing its rated at 475hp!! Other then that you would have to go top mount turbo like t3-t4, Gt30r,60-1,etc.....Cams that you choose really depends on what kind of racing you do drifting i recommend that you stay bottom mount turbo with a set of 256 cams or even 256 int and 264 exh. Drifting and drag 264 int/ 264 exh......With a top mount turbo drifting is more of a challenge and the turbo tends to fall out of the power band during low speed drifts. Im using a 60-1 rated at 575hp with a set of 264s and i had to use camgears to bring the power in earlier, but overall my setup is best suited for drag racing, highspeed drifting, and highway. I hope this was some help to you as i had to learn the hard way....

[mcdade240sx]

are you using .64Ar housing or .83Ar? Doesn't .64 give you less lag?

[mcdade240sx]

Also, is the rear diff in a 92 and a 96 240 the exact same?

[zenkisilvia]

im using .63 ar but it is a pretty big turbo 4" inlet 2 1/2" outlet!!! yeah the only difference inthe diffs is the rear cover!!!

[mcdade240sx]

how much for your T04?

[zenkisilvia]

i traded a guy a PS2 for it not knowing it needed to be rebuilt , I sent it to Majestic turbo and i spent $515... $340 of that was standard rebuild fee the rest was spent buying another turbine wheel. Normal price for one is like $650-750 !!!!
