A Couple Questions for ES P/A Class... I just finished pulling the motor out of the Z yesterday, and wanted to throw a couple of questions out there. It seems like the class rules have changed since I read them a couple of months ago, but I may be wrong. I thought I remember reading something about retention of the opti for ES classes and coil conversions being prohibited, etc. Here are my questions:
First off: "All other aftermarket EFI systems not permitted." Would an LS2 coil conversion with the LTCC be considered an aftermarket EFI system? It's more like a piggyback to the stock PCM in my eyes, just curious. Need to know what route to go on this one.
Second: "Must have mufflers." OKAY... big issue for me. I didn't run ES P/A last year, so this wasn't an issue. With my car being a rear-mount turbo setup, I have no mufflers. How will this fly?

>> Coil per plug conversions are permitted as long as it maintains an LT1 or LS1 PCM. So you're fine. Aftermarket EFI means FAST and other controllers that replace the factory PCM.
Second: "Must have mufflers." OKAY... big issue for me. I didn't run ES P/A last year, so this wasn't an issue. With my car being a rear-mount turbo setup, I have no mufflers. How will this fly?
>> Is it a single or twin setup? The ES classes only permit single power adders. If it is just a single, I would have no issue permitting your setup in the ES class. Dumped exhaust with no mufflers and open headers are what we are trying to keep out.

Okay, great Kyle. Thanks for the response. I have a single turbo, no twins here. I am shooting for throwing my LS2 coil packs on with an LTCC and my stock PCM.
Again, thanks.
Again, thanks.
