No More VTEC ;)

I haven't had much time for Project '88 lately. I have a couple a of kids and during the holidays I try to focus on them and family stuff. Now that the Holidays are practically over, it's time for me to get back on the ball and to get some work done.

Since I have my RM cam in my possession, I need to finish up modifying my rockers and locking vtec. In previous posts I notated how I had discovered that I was in need for some longer vtec pins. I also needed to remove the spring loaded pin in the last vtec rocker to eliminate a bind that I felt when the rocker arms are locked together.

Yesterday I got to work. My Dad and I started with removing the spring loaded pin. After closer investigation we found that the spring loaded pins were held in by tiny circlips. The little clips were such a pain in the ass to get to, even with the pin pushed down. I ended up having to break the pins which took very little effort. Once the tops of the pins were off, I could get in there and remove the circlips and the rest of the pin. It took forever.









Looks like the oem vtec pins are 10mm in diameter. I need some 10mm in diameter / 40mm in length hardened steel pins to replace the oem vtec pins. Luckily I found some on eBay in just that size and diameter. I ordered those today.



HAPPY early NEW YEAR! Track opens in 5 months. ;)

Time for More Air

I received a very special package from Rocket Motorsports yesterday.









Here are the cam specs:

Intake...   .480" / 254* duration @ .050"
Exhaust...   .440"/ 252* duration @ .050"

I took some pictures comparing my RM cam versus a stock y8 cam.









Random cam pictures...





And my absolute favorite part about this cam....








Looks like some grinding will be needed so the massive intake lobe can clear the head casting. So awesome. My plans are to build a z6 head in the next month and will use my RM cam in this head. Be on the look out for updates. Thanks for reading!

Rocker Arm Mania

Good evening. Recently I have been working on locking vtec within a set of z6 rocker arms. 

I read on a few forums that people would swap the long and short pins to lock vtec. That might work well for a B series but it does not for a single jingle.

I used a .25" thick nut to space out the vtec pins so they penetrate into each rocker arm equally. 

This seemed to work okay. 

The only problem is this:

The third rocker has a spring loaded pin. With my spacer pushing the vtec pin completely down into the third rocker, the trio assembly seems to bind. Not like a complete bind, just enough to notice a difference. Without vtec locked, the rocker arms move up and down freely on the rocker shafts. Once locked the rocker arms don't move as freely; as if something is misaligned making it harder to move up and down. I think that either the rockers need align bored or the spring loaded pin is somehow putting pressure on the assembly making it appear binding by feel. I have a hunch that the spring loaded pin is the culprit. 

I don't like the bind at all. In fact I am going to make modifications to eliminate this bind. How so you may ask? By removing the spring loaded pin and having one long vtec pin custom machined. Stay tuned!

Something Special is Coming my Way...

I will share the details when I receive my package from Rocket Motorsports. I can say this: this is camshaft has no non vtec primaries. The only sohc vtec cam that's not vtec. And it's big as fudge, puts the you know who's level X to shame. Stay tuned.

I had to post an extra large picture :)
