This is a daily driver street car, I want it to be quick tho, say I am cruisin' on the highway, I wanna be able to blow someone's doors in. I LOVE, when I am in first gear at about 5-6000 and punch it, and rip into second. But I want a camthat will be alright at higher speeds too. I like the CTR cams.

 

i just want to jump in here andsay good thread.

and i just want to reinput something i've heard about high rpm cars, try putting in pulleys not for power increases but to protect your accessories from the high rpm's. not sure how true that is, but it might be worth looking over if you pln on going anywhere past 9k

 

the diffrence in pistons is called pdd which stands for piston dome displcement. the higher the number the more compression. i just kinda wanted to share some info for the person who started this thread. anyway a stock b16 piston has around a 6. something and the b16b has an 8. something and an itr piston has a 4. something this is why it is stupid that some people pull their b16 pistons and put itr pistons they just lowerd their number

 

Well, as far as shivers said, I shouldn't have any problems with my clearances on my motor. That is unless I change the cam Timing with adj cam gears. According to C-Speed Racings CR calc, I should have around 11.5:1 - 11.6:1.
SHIVERS: how come you told me to compensate for the Piston to deck displacement with 0.000 instead of the stock 0.020. I know it is because the piston is bigger, but if it is 0.000 won't it be hitting the deck, then I will have clearance issues, NO? Or is the 0.000 just a rough estimate of it?

 

it means that the piston is level with the deck of the block at the height of it's stroke. thats why you should clay to make sure everything clears it ok.

basically when in the compression stroke all the air/fuel is compressed fully into the head before combustion.

 

Exactly ... and a b16b piston in a b16a block actually peaks out of the top of the block just a little bit. There's been talk about the c-speed calculator and it's validity for years. Some trust it, others just use it for an estimate. Some of the well known engine builders have questioned it's accuracy. By entering a .000 deck height, you are compensating for the small part of the piston that sticks out of the block at the top of the stroke.

As it stands, you should be fine with the CTR cams. But if you think you're going to go bigger in the future, it's better to pull the head now and clay the motor to save yourself any potential problems in the future.

Are all the parts listed in your sig/site in the motor already? If not, you'll need to pull the head for valves, pistons, etc. Since it's already going to be torn down and you'll have a used headgasket, claying the motor won't add much to the rebuild time.

 

Well, I almost have the project completed, Just waiting on my retainers to get here, and my new cam caps. Once that is done, I can get everything finished at the machine shop and taken home and put her together with the nice new wiring harness from RyWire.
