You are correct about the tubing and tip diameters.

Looks like you don't want to be slower than my SE.

Don't hide your project for long -I need some cheap mods this winter since I can't afford the cam anymore due to the $1750 trans rebuild.

Damn strait... The whole reason for buying the car was to see what times I could get out of a series 1 and to push the limits. I still want to run my car with stock pulley because I know that the car is good for a mid 14 sec. ET. Then I'll throw on the 2" pulley and go for low 14'*. Right now I have a few problems with my car that stopped me from taking it out to the track this fall.
  • The PCM does not like the 15 lbs. of boost and is dumping it. I think I have fixed this but don't like the fix. A custom PCM will fix this but I want to get a few other things done and some data logging before I get one.
  • Harmonic Balancer took a dump. I've looked at getting a custom aluminum made up but it will be too expensive. I'm going to get a stock one and lighten it up by about 15-20%.
  • Girlfriend wanting me spending my time and $$ on her and not the car. It gets really expensive when you are flying/driving to Rochester, MI every weekend and coming back to Bolingbrook, IL for the week.

I didn't want to say much because I didn't want to get peoples hopes up and not be able to get them to work but the project is (more like R&D):

1:8.1 Full Roller Rocker - I have found a whole line of 1:6, 1:7, and 1:8 roller rockers that can work for our cars. I can get them to work on a '92 head (3/8" bolt hole) or a modified '93-'95 head (drilled and tap 5/16" to 3/8" bolt hole). It just might need custom pushrods or custom spacer on the rocker. It will also need custom valve cover spacers. I have also found 1:7.1 full roller rockers that will work on '93-'95 heads without modification but you will still need custom valve cover spacers - they are also about half the cost of what’* out there right now. As for the other rockers they are about the same price of what’* out their now.

Ryan (JLAudioEclipse) has been talking to a few people and working on getting a modular pulley system for a keyed M62 snout. Only thing that might stop this from happening is the over all price.

Some other things I'm working on / saving up for over the winter since the Bonne is parked.
  • 3.33 final drive gearing - The 3.33 sun gear is very cheap ($17), it will just be the install that will kill me.
  • Shift kit and a vacuum modulator - To firm up my shift and hopefully save my clutches.
  • Custom A/C delete pulley that will allow you to bypass the A/C like on a L27. Pulley is made, I just have to test it out and make sure it works well. It will allow you to keep your A/C system just like the ZZP one but much simpler.
  • Custom light weight water pump pulley - it will weigh even less then the one I have now (looking for half the weight ~ 5oz.)
  • Custom light weight crank pulley - like I said above about 15-20% lighter.
  • PEMS and 3" down pipe.
  • Looking at P&P the lower intake manifold, supercharger, throttle body and maybe even upgrading the */C and TB.
  • Custom chip with adjustable timing, setup for 3.33 gearing, higher shifts, etc.
  • Custom full size IC - I just need to figure out how to get the fuel rail to work for a full IC. If I can't get a full sized IC to work then I'll probable go with nitrous.
  • Weight removal - my car need to go on a big diet not only to help the overall E.T. but to save trans.
