Corvette LS1 Ignition Coil Project..

I will be installing these soon .I will be using the MSD LS1 coils. You get 8 for $650 or their about $90 each.
I'll update this thread once installed.. Thank you RPM for his input on this .and to darkbrew for his help at
pointing me in the right direction. All is a go! If anyone one has suggestions pertaining to this subject please
post your experiences or proffessional advice..Its seems as though it will be easy from what I've gathered so
far.


Sorry Above Project Has Changed under advice from MSD Tech and is as follows (2) MSD pn# 6302 and (4) MSD pn# 8207


Please read thread " MSD Ignition Project"

Thanks I will. Looks like I'll have 4 extra coils when done if it's a 100%
success , I will part with them for half of what I paid for set of 8 . $325 -$350 depending on shipping costs..


Above Set up is void! Please read on to see changes!

Note : I've picked MSD because when talking to Tracy at Rotary Avionics he said that OE LS1 coils have a delay/duration built in.. It makes a bit of sense because I later read the following Quote in product description..

Here

The complex electronic controls of the original coils presented the aftermarket with a challenge as the drivers that control the firing of the coils are built into the OE models. MSD engineers were able to design an advanced circuit that will operate with the factory electronics..



The only thing that will require modification is location and Plug in interface (wireing) as one is 3 wire other is
4 wire.

sounds interesting, do let us know what happens.

the OEM coils have a delay built in? that's an interesting "feature"... are you quite sure the MSD coils do not have this same delay? from the quote above it sounds like they will behave the same way and mess up your timing

I think MM was going to look into this, might want to check with him also

if you haven't bought it yet I have everything including the wiring diagrams and will sell it for less, except using the better LS2 coils

I just never followed through on pursuing it, never seemed to have the time

edit: these are the GM OE coils, brackets, wiring harness, and MSD plug wires. I'd recommend doing it this way first as any mistakes will be less expensive.

Thanks.. Quote from MSD /LS1 coil packs

The complex electronic controls of the original coils presented the aftermarket with a challenge as the drivers that control the firing of the coils are built into the OE models. MSD engineers were able to design an advanced circuit that will operate with the factory electronics..

They are different ..But this is experimental.. I'll be the first to try (fail or succeed). But I really believe it will work..So do others.Wish me luck!

a) that's just a general quote from MSD regarding the GM product

b) you need LS2 coils, not LS1

see my previous post, $125 shipped for 8 coils and accessories as noted

my intention was to first prove the concept, then get the MSD coils

I'll get back to you on that. There is a reason LS1 coils are more ideal .Tracy at Rotary Avionics mentioned something about that when I asked him about it.. I just cant remember what the details are.. If I find it I'll let you know. If you discover anything let me know. Thanks

Thanks I'll get back to you on that..Sounds like a great deal! .. I like MSD's solution to built in driver. But I will consider this.. Why are the LS2 coils better? If you have answere readily available please post it.Otherwise I'll google it up and post back.. cheers

they all have a built-in driver for this style coil, including the OE coils ...

what I have is all new, unused parts

Cool. Sound's like a smokin deal.. I;m still waiting on Ron from RMJ Racing (Alberta) to get back to me on wiring and compatability.
When I mentioned the LS2 coils he said that MSD LS1 coils would be better suited ,but said he would talk to some friends/sources
about it.. Ron @ RMJ Racing is a veteran drag race engine builder in Lethbridge Alberta . He owns 2 6 second cars with 1000+ HP..
Great guy to deal with.. His expeirence is mainly with American V8's , but he has been all over and has alot of freinds/rescources..

just so we're clear, these were never used by me

they are new OE take-off parts that I intended to try and make work on an RX-8, but never found the time to pursue

Ok this may change everything..Just got some advice from tech at MSD .. This guy is a rotary nut and said he had a excellent solution that will work guaranteed. Set-up is as follows:


2 MSD part # 6302 /INFO:LINKhttp://www.msdignition.com/2007/light.html


4 MSD part # 8207 /INFO:LINK
http://www.msdignition.com/coil_blaster_6_8207.htm

I'm sorry,but this looks like the way I'm gonna go now..This info provided by MSD tech was much needed
and more reliable than frankensteining it..and hoping for the best.. Sorry if this has let any members down..

I will post results / pics when completed. Expect to hear
back from me in couple weeks with results..

good luck

by going that route you'll be putting an entirely different aftermarket ignition system on it before you're done

edit: BTW, sold my parts to someone else

Coils are $40.00 each and Adapters $70 each..New ignition system for under $350 dont sound bad..
MSD tech assured me it will work very well ..
Still I've got Ron from RMJ Racing looking into it..
Its gonna need to make sense to him before giving me the OK..

I'd be interested to know which MSD tech you spoke with.
I have a bridge to sell him.

Thanks for edit .. I felt that The MSD Tech (Dre) was kind enouph to help..I was referred from one tech to another , then that tech said he would get one of their more experienced on rotary's guy's "Dre "to talk to me. It has been done with success and he reassurred me it will work.

Thanks again
