My 11:1 C/R NA build
Its amazing what people know who can't build an engine isn't it? Nice work, I was telling somebody today that if I was smart I would have spent all the money I did on the Z on tires, brake pads, and track time. Enjoy the hell out of it, its your car. I am going to guesstimate 267/255 hp/tq on a dynojet sae correction with a sweet torque curve.

Headers are nothing revolutionary and have been widely debated throughout multiple threads, however they appeared to be leaps and bounds better than what was on there, so I'll roll with them until I have a reason not to. Once the tune is done hopefully they'll add something. If not, they sound pretty damn good so it's not a complete loss. I'll have to get a better vid of a fly by etc. to satisfy the curiousity of Importdemon.
Unfortunately I wont have a baseline for any comparisons with or without the headers, which as far as I have found, has remained an online mystery as to what the megans actually do on paper.
They can be purchased here:

And cheers 1cockyz, Gabe, Z1 and anyone else who has built there motor that knows what goes into it.
Maybe in the future, but for now, I'm happy its back on the road w no leaks or issues.
It's been complete for a while now, just thought I'd post it for the community benefit as while the build was going on I scoured any and every thread related to the topic. So I figured I would contribute what I could in return.
One thing that I do love about forums though is that once someone posts up descent thread, everyone says why didn't you do this or that, or if you would have done this then you'd have a bad a s s setup.....yada yada.
As if I haven't done the research or that I didnt realize that cams/head work would be beneficial.
How many kilojules does the Z put out anyways?
When all of you have done your own build I'll be sure to chime in with what does what or what you should have done.
For those of you that have built your engine, congrats. I'm sure you put as much time,effort, and research into it as I did. I would be willing to bet you were happy when it was all done regardless of what others would have done with their gazillion dollars.
As for the complements...thanks guys! I'll have to get it dyno'd and report back. This wasn't a 'I'm gonna make the fastest Z on the planet" build, so for me, it's going to be more for information than bragging rights or penor size comparisons.

What is the intended purpose for this motor?
Like I said good luck, but perhaps drop the somewhat incendiary, confrontational language that only you and a few others have any idea what is going on.

I somewhat agree, but there is power to be made on stock heads. You yourself saw noteworthy gains from just an upgrade to 264's. One would think with the addition of a bit of compression these gains might increase incrementally over that of the stock compression. That's speculative of course.
Your initial post never stated any sort of goals, etc. I brought up the cams because it is somewhat a-typical to see an N/A built shortblock with stock top end. I have no doubt that you put forth the effort in searching for your needs. You are going to leave yourself open to criticism any time you post on a public forum.....its just the way it is. Not everyone sees things in the same light.

Pfft....I'm feeling a bit bullish...271/260.

I hear ya man. I guess my patience runs thin when it comes to internet boards...hence my low post count and reluctance to even share it. I bet there are quite a few people out there that dont share to avoid the critics.
Anywhoo...I'm proud of this project and think it came out great for what I needed/wanted.
The goal was to rebuild it instead of purchase a different motor with unknown issues. Mission accomplished. I liked the idea of putting the first mile ever on it and being able to take care of it right from the start, opposed to spending a considerable amount of cash on someone elses abused engine. I know there all sort of checks and measurements to ensure a used engine is a good engine, however when it came down to spending thousands of dollars, I chose this route and I'm happy with my decision. Albeit a more expensive route, I think its worth it.
It gets me from A to B, thats all. As for powa numbers I'm curious, but like I said, it really not all that important to me. It pulls good and with a tune I think it'll be pretty quick. I'll report back once I get it dyno'd for my second dose of criticism.
I kid, I kid!

Wow. Talk about coincidence. I'm looking for info on rebuilding my oil guzzler 06 and the first post I open from search is from a fellow Z owner in Phoenix. I'm in Mesa. So I was wondering if you could give me some more info on your build. Which shop did you have the machine work done at? At what was the down time for the whole process? Thank you in advance for you help.

I'm mostly looking for opinions on local shops to go to or steer clear from. I'm sure there is plenty other info I'll find searching around. I just like getting as many opinions about shops as I can.
Looks great !
stock Tune btw ?
i say you should have went with cams since ur engine part rebuilt...
good luck and keep up the good work !
ps : nice engine pics, u just gave me few ideas...

So did you stick it out... Cam-less? I lasted about 1 year before realizing I made a mistake. I was in the same position as you un-planned rebuild didn't want to put a further $1000+ in.
But I have to say even without the cams, properly built it still feels and sounds great.

I think with me doing all the work myself it was just under 5K, but my motor was blown forcing my hand.
How much power did you net?
You can do a build for just the cost of cams and valve springs if your bottom end isn't burning any oil. The bottom end has been proven to make almost no additional power, so unless you have blown the thing up or are consuming a lot of oil - there's no need to do much bottom end work!

the bottom end never makes power unless you increase displacement by a meaningful amount - but it does need to stay together. On a non revup DE, that is of particular concern, particularly if you mate it with a cam that needs to rev
as for looking for more power on a budget on a non revup DE, aside from your basic bolt ons (spacer, exhaust, tune, gears), there really is no magic way to do it on the cheap unfortunately
