    I have a jdm zc single cam vtec and im putting a greddy kit on it very shortly n im trying to find out how much boost it will handle on stock internals. Ive heard it will respond well if kept between 6-10lbs but i also heard that the rods give out at 220 so if anybody has a more defined answer on what this engine is capable of i would appreciate ur answers. btw, im talking about with a good tune not just a slap n go.

    A bone stock healthy D-series can run reliably on 8 pounds or less.

    Are u saying 8lbs is the limit on a stock application with a healty engine n a good tune. I also dont know if it matters but i do have a skunk2 manifold and larger throttle body im not sure if the larger plenum alows for more boost or not. Sorry if it soumd like a dumb question but i am curious

    If you want more boost, you're going to need to start replacing bottom end components, such as rods and pistons. After that, you'll want to sleeve the block. But no, the manifold and throttle body won't allow you to run more boost. Its the bottom end you need to be worried about. But like I said, go with 8 pounds and see how you like it. If you crave more, you're going to need to beat up the wallet a bit.

    Yeah i hear that i was talking to the kid im buyin the kit from he said he was tryin to blow his shit up at 10lbs and the thing held like a champ on a stock bottom end. But i appreciate the comments i thinnk im gonna start out at 6 and work my way up from there to about 8 to 10 and see how the engine feels.

    Unless your a motor whisperer there is no way to see how your motor is doing on "x" amout of boost. You crank it to ten you can ask your motor, "Is that OK?" nope youll just slam a rod through the block. You have to build it to take "x" amount of boost. Like I said my friend is running 7lbs on a D15B Sol, and it gets done the road pretty quick on 7lbs.

    Remember guys, it's not all about X amount of boost. A larger turbo will make more power at say 7 psi than a smaller turbo will at the same 7 psi. Because of this variance psi or boost isn't a good measurement of how much stress is put on a motor.

    whp is an indirect measurement of how much force is exerted on the internals, it's also measurable.

    From what I know the general consensus is that the D16 rods are good until about 220whp or so. Some people have successfully made much more power and been fine, while others have blown their motors on much much less. It's all in how good the tune is, if it's detonating it's not going to last very long.

    The larger throttle body and manifold will allow your motor to make more power over your stock parts, how much more I don't know.

    What I would do is work with the wastegate spring that's at the lower psi range your looking at and also get a boost controller. Then get the car dyno tuned by a professional, tell him how much power you want to run, he should know what to do.

    Speaking of boost controllers i picked up a manual boost controller today from a friend an im a little confused on the routing of the vacuum lines. Theres a line that comes off the twist nob piece that goes to a small block and at this block there is two vacuum outlets. On the turbo which is internally waste gated there is a line that goes straight from the acctuator to the compressor side of the turbo. So where exactly does the boost controller plug in at.
