Well, this weekend I finally got a chance to take my working mini-me to the track, with the goal of breaking into the 15's...and did it. The first time I went to the track, I ran my stock D15B7 with I/E and ran a 16.9 @ 81 with a shitty 2.4 60ft. I did my mini-me swap, and went to Englishtown and ran a 17.3 @ 78 best with a horrid 2.5 60ft...I didn't get lower than that at all that day. I didn't know what the hell was wrong. I then discovered that I forgot to pull an oil jet in the block that makes VTEC activate. I did that, and didn't have a chance to get to the track until now. I was running consistent 16.1' with 2.3 60fts, and I got the 60ft down to 2.2 for the last run and was rewarded with a 15 second timeslip. I'm very pleased with the results, and I have an EX tranny waiting to be installed (as soon as I get a new clutch). After that, i'm going to upgrade my header and exhaust system, and slap a cam in there. I want to have 14's before I start modifying the bottom end.

That's pretty impressive, especially the fact that you ran it in a 4 door with a DX tranny and original clutch. I just put together a mini-me using a B2 bottom, and I'm a little curious to see what it will run. It's in a 88 hatch, so I'd be happy with mid to high 15's on street tires. Good luck with the further enhancements to the motor.
Yeah...DX tranny is a big 's. However, if you read my VX wheel thread ( http://www.honda-tech.com/zerothread?id=629535 ) you'll see that having the 175/50/13 tires helps a lot in terms of gearing. I'm really looking forward to a new clutch and EX tranny...
I thought it did...I only ran once with the 15" pirellis (16.4 w/ 2.4 60ft)...with the 13" sumis, I immediately dropped 3 tenths (16.1 w/ 2.3 60ft) and eventually got my best run in with them (15.9 w/ 2.2 60ft). They are actually pretty damn sticky, I had to cook em before each run though...it was awesome!
Here is an interesting comparo of the sumi's vs the pirelli's with similar 60fts-
195/50/15 Pirelli P700-Z on Integra LS wheels:
You can see the difference...with the civic VX wheels at the 1/8 mile I was .06 seconds behind and 1.5 MPH behind my other run, and at the 1/4 mile I was .01 seconds ahead and 1 MPH ahead of my original run. So, in the second half of the run, I only gained a tenth of a second, but on the other hand I did gain a whopping 2.5 MPH with the VX wheels, and I had an overall better run with a worse 60ft...not bad at all
congrats on the improvements
I would suggest doing a little weight reduction
I've ran 9.8s in the 1/8th with a d15b7, mostly just boltons. I think dropping some weight should really help, and no doubt the ex trans is gonna bring you down probably 3 tenths at least. You have a good platform to build on though.
