OK so I like to tinker and can be a bit of a perfectionist and have been known to do things because I can. <P>I have just replaced the coil pack on my 89 with a Jacobs JAC-321412 Ultra Coil Pack $82.69. This is the single 6 outlet coil "Bricks" as I call them. Some later models may have 3 of the 2 outlet coil packs. JAC-321411 99.99 for the 3. From Summit Racing 1-800-230-3030<P>Incredibly easy to install. The old and new coilpack have the wire locations numbered. Just pull off all the old sparkplug wires and remove 3 torx screws per side and disconnect the spade wire connections underneath. The old part and the ECS both were as clean as new and even shone. No evidence of any heat conduction grease, goo or anything, just spotless! <P>I applied 5 lines of dielectric grease and put a dollop on each spade. Reconnect the wire spades to the right connector and tighten up the torx bolts and you have installed your new coil block.<P>While I was at it I installed MSD 8.5 mm Super Conductor wires.PN 32789 $54.39. They are designed for a 3800 GTP supercharged engine. The wires 1 and 3 are slightly short because they come from the left side of the coil pack and on the GTP from the right side. I have them installed and I don't think that there will be any problems. I do not like the stock parallel wire holders as I believe they create inductive and capacitive problems. I enclose my sparkplug wires in black plastic split loom for a bit more insulation and to reduce crossfire. Probably over kill? The Reatta uses heat shields with metal tabs in the rear and can be reused. On the Riviera it uses the stupid spring attachments on the heatshields and they give miss firing error codes. Took them off and 1,000 miles later all continues to be well. I like these wires! <A HREF="http://www.msdignition.com/1wires.htm#anchor164757" TARGET=_blank>http://www.msdignition.com/1wires.htm#anchor164757</A> <P><BR>Fired it up and all ran smoothly. It was a bit rough at speed on the highway but I blame that on the old tires that I removed the weights from to polish the rims. New Yokohamas are going on this week with a Hunter's GSP9700 Vibration Control System balance <A HREF="http://www.gsp9700.com/index.cfm" TARGET=_blank>http://www.gsp9700.com/index.cfm</A> <P>I also only had 3 of the new struts on and the alignment was off quite a bit. <P>Later all...

Robert,<p>Thank you for making the rest of our lives with our Reattas easier. I like to make these same kind of upgrades, but I like it even better when someone like yourself has already done it an makes it as easy as:<ol>[*]Obtain part # or #'s x, y, z.[*]Install per detailed instructions[*]test drive[*]enjoy!!!

<br>I see an upgrade in the near future.<p>Cheers,
