I user by the name of Troubled81 has a thread similar to this but has gone silent. I’m not going the same path so I figure I’d post what I’m trying to achieve and where I’m currently at.
I’ve owned quite a few speeds but currently just own two speed 6’s. A 06 and 07. I picked up the 06 for 500 bucks clean title rust free. Engine runs but I’m looking at something much bigger. Originally I was going to modify my very clean 07 but have since realized what I would be ruining.
Currently have a 2.5 dura and a 2.3 on the engine stand.
I want to ditch the entire DI system and runs stand alone ecu capable of my needs without having 3-4 different systems and controllers in the cars like most speeds are.
I recently figured out how I can go “stand-alone” while keeping the basic interior functions such as (cluster, a/c, and more if the BCM is happy). I’ll be doing a piggyback setup with either a Haltech 550 or 950. Ive never done a piggyback installation but with the 327 pages of electrical diagrams and pin outs I’m thinking about giving it a go. Im also trying to figure out how I’m gonna drown this engine with the appropriate fuel without sacrificing idle and drivability. Currently looking into how and if an ecu could selectively run two sets of injectors. A smaller set in the stock 2.5 port location and a large set that would reside in the 2.3/2.5 adapter plate sold by Damond. From what I can tell that flange is just a port matcher/spacer. (Same bolt pattern).
The 2.5 hybrid isn’t quite figured out yet as I was originally going to run 2.3 rods and crank. The 2.3 wrist pins are 22.5mm dia where the 2.5s are 21mm dia. I’ve looked into forged 2.5 rods and the choices are slim. Found a company by the name of Molnar that sell a set for 400+. They don’t state any sort of hp capability although not a big deal I’m still skeptical. This thread will be a long winded one maybe stretching into the winter months. Hope y’all are down for the ride. I’ll try to post everything I learn or have issues with.
