I have a stage 2 turbo w/ an upgraded fuel set up on my 99 RS. My next step is to upgrade my ignition. Unfortunately previous posts haven't been too clear on whats needed. Heres what Im getting, please correct me if Im wrong w/ any of these...

MSD DIS 2 programmable -6212
MSD Coil - 8229
MSD Wires - 32279
MSD Tach adapter - 8912

Heres the parts that are unclear. We need 2 tach adapters right? Are they both the same part number or are they 2 different adapters (if they are different whats the part number). Also, in an old post someone said something about a 3 bar MAP sensor. Do I need this cause Im running boost? And my last question is that ther was a post that said that there is a coil for our cars with the part number 8239. Summit has it listed as coils w/ flat pin terminals. Which one do I use - 8229 or 8239? Thanks in advance!

you dont need two tach adapters

edit: the coil pack, just disconnect the one you have on your car to tell if its the flat pin or the circles, diff ones for diff years. on my 96 esi talon they are round

you need one tach adapter for our 420a engine. and a 2 bar map sensor for the ignition is 20psi max, and 3 bar map is 30psi max. difference of $10-15 bucks only.

Do I actually NEED a new MAP sensor when I install the ignition? I cant figure out why I would.

the msd map sensor is for the ignition system to retard timing etc you dont remove your old one that stays on the im.

Got it. Thanks again.

I used to think you needed an ignition to run high boost but that isnt the case. I run 16 psi with stock ignition and no problems.

every car is different in regards to timing/retarding. some people need it at 15psi some dont need it untill 20psi..
