IMO, keep it simple for that power level. Manley H-Beams with standard rod Bolts Manley Pistons 88mm OE Rod and Main Bearings OE Head Bolts OE Head Gasket

Nope, you're correct, we're just talking about two different things. It is true, when testing distortion of the cylinders from a TQ plate, it showed that cylinders did not distort much at all, making it unnecessary to use a plate when boring/honing. What I'm talking about here is the...

Very well said. The only thing I would challenge is the CS cams. My major beef with just about every cam design for us is the low lift in all the profiles. Everyone talks about valve lift in terms of the point our stock ports/head become saturated/cannot flow any more... What few talk about is...

Nope, to clear things up, stock hardware are TTY Head BOLTS, that do not need to be re-torqued. Everything else is a head STUD and does require the re-torque.

Nothing wrong with them really. For me it's just that they're not aggressive enough in the ways I feel they should be. That and lots of people don't like regrinds and would rather something cut from a blank. The piper cams are more along the lines of a "real" cam, though not perfect either IMO...

Personally tell people go stock bolts unless going over 450tq. Stock bolts also do not require a re-tq procedure, which I would advise for any stud.

All good. I was way past due for starting to bring stuff over here and get discussions going again. I just couldn't take it with the platform anymore and needed a break the past year. Also, this was something I had originally written for FB a while back, so I didn't have to do all that much to...

I also want to link a few threads here that I recently posted on MSO. These are some of the more important topics I wanted to make sure and bring over for discussion here. http://mazdaspeeds.org/index.php?threads/open-tuning-turbo-theory-discussion.3332/...

Let me dig up some more "bolt-on" turbo logs and overlay those as well. When I originally wrote this, the S4 didn't even exist yet and I was personally hating the S3 on the few cars I was working on with them, so I didn't even include it. The 2867 is a great turbo i that range, though I still...

Alright I'm copying this over from the original, extremely beneficial http://www.mazdaspeedforums.org/forum/f106/lets-talk-about-head-studs-135380/ thread. That thread, great as it was, is now insanely long, dated, and recently filled with garbage. Please feel free to go back and read through it...

I pulled this over from a post I had a while back, while I was working with Web on what I would consider actually useful cam grinds for us and working with Teo on tuning a set of "big" cams Piper had sent him to try in his AWD speed 3.. I stopped all Mazdaspeed development of any kind last year...

I was about to start a thread with this writeup I did a while back, but I think this is a good place to keep the turbo sizing discussion, so I'll post it in here. I had to modify this slightly from when it was originally written because the S4 was later produced and became a turbo I would now...

End of the thread derail finally. Sorry about that Cas. http://mazdaspeeds.org/index.php?threads/married-to-mazdaspeeds-stories-of-progress-and-lols.3344/#post-27108

Alright, so since I FINALLY decided to start posting on this new forum, I realized my words held little weight with my Greenie status and all, not something I'm really used to, but completely understandable. With that said, I wanted to give a little Bio to those who don't know me. I will keep...

When Cas talks about us experimenting, personal experience with ZZB, parts, fabrication, etc, we're talking about 2009, 10, 11, etc before there was any of the cookie cutter setups that work today. Maybe I'll make a thread kinda of outlining the history of everything, so it all makes more sense...

No need for a discussion. What do I know anyway, I only have 4 posts.

I had a long post typed up for a response, but I decided against it. Anyway, ironically Justin just posted a dyno sheet of a very well running/tuned S4 on stock block, which perfectly illustrates my point. Same peak TQ as Cas, roughly same rpm for peak TQ, but it can't hold that TQ at all and...

Meh. My response was coming from the view point of a protuner, who's seen more setups, both good and bad, than most can even imagine. Also, There's a lot more to the relationship between power and heat.

As Sho said, his engine is still running in another car and Jake's engine is actually running in my 6 still, now with >130k on it, and compression still 180+. I've personally seen a lot more damage from small/inefficient setups being pushed than from bigger setups running efficiently. Not...
