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 :) 

More Pictures

The pictures I posted didn't do any justice to how my intake manifold looks. Here are some more. Enjoy!











I can't wait to get my new die grinder and porting kit. This baby isn't even close to being finished yet.

Longggg Over Due Update

Hi there! I didn't realize it had been so long since I have updated my dear old blog. What a wild ride this past summer was. A lot of good and bad things occurred which kept me from reaching my goals nor even making it to the track once. Ughhh. But life is good now, things are going much much much better. I have a ton of motivation to get things done to my Project '88.

Last time I drove this car I bashed my TPS against my firewall during a hard shift. My Blox intake manifold sits so damn close to the firewall. I punched it out a bit but that wasn't enough. I removed my intake manifold so I could really work the firewall good. While I have the intake manifold off, I decided to take a peep inside of the plenum to see what was inside. I was not impressed. I started to get to work.











I started to get ideas and began to work on the ports. I had a basic dremel that I was using before I pick up my die grinder and porting kit. Here are some pics of my progress so far...





Here you can see how I enlarged the mouth of the roofs to hopefully promote a smoother and higher velocity of air flow.





It's a work in progress and I have a lot more work to do.

I also have some goodies coming. These goodies are really going to improve my set up! Stay tuned.

Interior Almost Finished

More work done today. I ran out of paint before I could finish. I will be picking up more paint to finish the job. I think it came out rather well. Here are some updated interior shots...






The new seat bracket that I made and welded on came out sweet...



A fancy photo that I doctored up...



After this I'm going to remove my intake manifold, massage the firewall for more clearance around my TPS then I will be ready to hit the track.

Getting There :)

I've been working on Project '88 as much as possible. Here are some progress pics. I'm going to finish up my small to do list and will be ready for the track. Great news about that. A friend has stepped up to let me use his truck and trailer to get me to the track. It's going to happen soon! Back to today's progress....
