Here is how the engine looks now:



Here are the current engine specs:

- D16z6 Engine.
- P29 pistons (12.5+ compression expected).
- 75.5 bore.
- H22 Throttle body (60mm)
- all new seals, belts, rings, bearings.
- new water pump.
- valve seating job.
- NGK BKR6E spark plugs.
- New spark plug wires.
- 3" intake w/ pipercross filter.
- 2.25 exhaust with 4-2-1 manifold.
- Exedy clutch.
- Oil catch can (catches both from pcv and head ).
- P28 ecu.

The car is currently on the engine break in period (400 miles in and 600 more to go).

So today I got an offer to buy a used comp camshaft 59300 for ~ $140!

I have had mixed feelings reading online about this cam, but so far this is what I have got from it:

- The cam makes more power and pulls stronger until redline - 7200/7400 rpm.
- The cam does NOT need upgraded valves/springs/retainers if it is not boosted or revved way above the stock limiter.
- The cam does NOT make power after 7200 rpm, so it is not worth revving it much higher.
- The cam is said to make excessive noise at idle.

However, having all that said I think it probably is worth to buy it and drop it in before the dyno day.

What do you think? Maybe you guys have experience with this cam NA and could help me out?

i was always under the impression that it was a decent cam for the sohc vtecs. im sure there are better but for 140 bucks ....

It's a good cam and well worth $140. Only thing I would stay away from for sure is Bisimotor stuff. I've seen too many of them break and wear rockers out in only a few thousand miles. Lots of info over on D-series.org about this stuff.

I like your radiator stay bracket Lol.

It's probably good for 8-10whp. Not bad for $140.

While you can drive it without upgraded springs, I'd advise against it. Valve float killed a motor of mine several years ago while I was using the same cam.

We have very similar builds.

A high compression d16z6 will benefit from a good camshaft. If you haven't done so already, check out d-series.org. It's entirely dedicated to d-series knowledge and you'll have no issues finding fhe answers you're looking for either by searching or asking.

Good luck with your build.

the d-series guys seem to love the 59300 and from what ive read its the best bang for the buck on a relatively stock to mild build. my buddy has a 59100 on a y8 block z6 head setup, stock bottom end, stock port head with S2 flat face valves and made 137whp.
