Hopefully this afternoon I will have some measurements for both the MY99 WRX valve and the MY98 WRX valve to publish. If the length is an issue as you've indicated, I'm more inclinded to machine out my hydraulic buckets into solids to suit each position. |

Having said all of that, I did have some problems with my valvetrain...I think the installed seat pressure wasn't enough on some so they let go. I also think the shim overlapped the valve stem too far on some to the point where the shim was pushing on the collets...which in turn meant the valves dropped.
I plan (when i have some money) to completely redo my heads again soon. M |

I'm not convinced it lost power... but then it never really made any power. The static timing has been set reasonably well...it's not perfect, but it's not out by orders of magnitude.
I was reading a Toyota V6 article the other day and they solved the problem, by making the timing gears adjustable as well as the toothed belt pulley...so in theory, three adjustments for cam timing. In the longer term, this is what we'd need to do if you were chasing the perfect cam timing. M |

I've got that timing and crank sensor info for a MS if you want (although I think I sent you a scan??).
Dwell is the charging time...charge too much and the coil overheats and fries, but the spark is big (bigger spark=better bang), charge it too little and the spark isn't enough to get the engine working. The SVX coils are dumb coils...the later WRX/STI onwards have built in ignitors. The STI coils are a viable COP option, whereas LS1 or Bosch (as I'm going) will require a lead. |

Bazza, for sure. Although, check the boot length. I have the EZ30 ones and the boot is too short. I believe one of the STI boots would be a better fit.

Definetely - I can look up the part number for the boot if you like? The EZ30 coil will prolly be cheaper as most pay more as soon as anything says STI :P So could work out cheaper with EZ30 coils and STI boots

If you could that would be great thanks. I remember coming across a site that referenced the boot lengths...but I've gone and forgotten/lost the link.
Then I can unload my bosch ones and try again. Thanks, Matt |

Actually, if you have a source of the loom plugs that suit those coils too, that'd be helpful...the 3 wire plugs.

I'll see if I can find those part numbers for you. Last edited by bazza; 06-11-2012 at 09:11 PM. |

Sorry, cannot find the actual boot but this might be handy:

Actually, I think this post is more relevant.
http://www.rslibertyclub.org/forums/...=1#post1069667 I think we need the longest one, but my memory of when i had them side by side is hazy. M |
