I just wanted to tell everyone that I got my Crower valvesprings and retainers on Saturday. Now I have...

-SRP 10.5:1+ pistons, exact application for these pistons are for a D15(CR is going to be ~12:1)
-Shotpeened and polished ZC rods
-Crower titanium valvesprings and retainers
-AEM Cam gear
-AEM Fuel Rail
-B&M FPR

What I still need...

-Zex 59300
-Piston rings
-Rod/Head bolts
-Race valves or equivalent
-VAFCI/II
-Rod bearings
-B Series fuel pump
-a few AutoMeter gauges
-Timing belt stuff
-Head gasket
-motor to build
-MSD ignition
-Hondata IM gasket
-there may be some stuff that I missed

and that's about it. I knew that once I got the rods and pistons about 2 weeks ago, everything would start to fall into place as well. I plan on doing the build between Christmas and Feburary '04, just depends on the money situation and transportation constraints. All questions and comments welcomed.

...someone give me some input on what the best places are to get the stuff up there...

BTW: This is all going into a '99 Civic EX coupe with I/H/Testpipe/E and clutch.

I might be able to make you a deal in the near future on a brand new, still in the un opened box,comp cam 59300

 

Is the 59300 the Zex street/strip for the z6?

 

yup,, its for the Z6/Y8

 

why did you go with such a low compression?

 

this may be kinda after the fact- but the stock retainers should have worked fine for that setup. they should be able to be revved to 7800 w/o breaking. ti retainers are notorious for wearing quickly, and need to be checked and replaced every so often, depending on how much u drive. the srp's are a good choice.10.5 is a good streetable compression that will still give u hp gains. zex 53900 can be used with a y8, but i believe u need to advance the timing 4 degrees to bring it to 0 timing on a z6, which is what the cam is made for. hondata im gasket is a good choice. its supposed to prove very useful and is only 60 bucks. in my book. 3-5% hp gain for 60 bucks is pretty damn good. u might wanna look into gettin a larger throttle body, ie oem 60mm one from b series motors. they can be found in the classifieds for like around 50 bucks, and should help throttle response, and maybe add a couple ponies. oh- camgear- just stay away from aem cause they have a tendancy to slip. i got a str pro series camgear for my z6 for 80 bucks new from landspeedracing a few months ago. they are supposed to be pretty good, so check into it to see if u can find one cheap. ok i keep rambling on, i think i need sleep now

 

Stock springs cant somtrol valve movement far past the stock redline when used with a high lift/duration cam

So you're saying that going from a stock, 9.6:1 to at least 10.5:1 compression is low? I don't really think you know what you're talking about. 10.5:1 is the highest compression ratio pistons made by SRP for a D series. One thing I changed in the original post is that these pistons were intended for a D15, thus, the compression ratio in my Y8 is going to be significantly higher without milling the head and/or getting a Mugen headgasket. Keep in mind that this car is a daily driver and is driven 50+ miles per day, it just depends on the mood I'm in.

 

Just calculated up what my compression is going to be...

11.95:1 without any kind of head milling or high compression headgasket.

I would have to say that 10.5 is going to be a little low for what your looking to get out of your build... I would recomend going with at least 12.0:1... 12.0:1 is perfectly safe on pump gas if properly tuned and the increased overall performance and power you will get out of a higher CR will make it all worth it in the end.

 

Whats the CC difference in the D15 and Y8 heads? 11.95:1 sounds a little high

That's what it's going to be. Here's the three websites I used to calculate my compression ratio...

Compression ratio calculator site. I took the exact spec. numbers for my pistons and my motor and then hit calculate.
http://www.c-speedracing.com/h...c.php

This is the site for my pistons. I have the very first ones on the list.
http://www.jepistons.com/pdf/2...a.pdf

This is the site for the specs of my motor. D16Y8 is my motor.
http://www.muller.net/sonny/cr...t.gif

If you don't believe me then you can input the numbers yourself and see what you get.

 

1. Don't ever trust those compression calculator sites
2. The D-15 had a differant compression height than a D-16. Basically the top of the pistons will sit outside of the block.
3. If you really are going to run this set up, clay the motor

BTW:I will be running 12.6-1 compression, on pump gas

10.5 IS low....if u wanted something higher then shelf u couldve got a custom

_______
not the smarted thing to do ...i wouldn't go over 11.5 on pump gas...just my 2 cents

 

GRANT!!!!!!! HEY MAN.. MY B16A IS GONNA KICK YOUR ***! Do you know who this is. I drive the fastest bondo civic in town with the loosest altenator belt ever seen. lol. You have a set of si wheels? I want em. How much? Good tires? I will be down there tomorow on lunch with my new engine d boy. ha-ha. I like the bkilla thing though, but why do you have a big cow dick and ***** all blistered for your avatar thingy?!

Good thing I don't care if its the smarted thing to do . 12.6 can safely be run on pump gas day in and day out if you know what your doing...but hey, if your scared, say your scared

you should a Hondata Fuel Mangement to that list. but anyways everything looks good keep us updated.

Not that it really matters if you put the right numbers in but at least use a dseries comp. calculator. Here's the site:

Should have just gone with the zc or a1 pistons for the street, it would've saved you $$$

I got the 89-90 A1 pistons in mine. Gotta love that high of compression for 140.00

 

James, I'm DSeriesBkilla!

 

static timing is 16.5 ahead of TDC on the D16Y6 and 18.5 on the D16Y8. I was messing around with some roms earlier, and this came up.

Behind TDC? I dunno, so for the zex cam, you'll use whichever is the appropriate timing.

-PHiZ

 

nice. good luck

I paid $300 shipped for the rods and pistons. The pistons had 1000 miles on them so I got them b/c they were cheap. They guy who had them before me had them in a D16A6 I think. I'm going to check out that D series compression calculator out and let you guys know.

 

The D series calculator gave me the same exact compression as the one on cspeed.com....
