| C4 LS swap with ZF6 trans |
Subject: C4 LS swap with ZF6 trans by SpectatorRacing on 2011/8/15 13:11:45 I might be taking the plunge. I'm tired of having to run heavy because I have too much HP (tough life, eh?), and I don't like LT1 ignition systems, even with the Delteq. Trying to choke off power caused the issue I posted last month, so that's not the answer. The LS1 advantages for me are long in number... My target HP is about 350 to the tire. LS1 with headers and a decent cam will get me there. This means stock motor reliability. With the lower HP I can drop about 200 lbs from the car. The mythical 2700 lb C4 will be reality. So nice. A higher revving motor makes my 4.10 rear gear a little less of a problem on the track and saves me $1000 in a change. Stockish motor means my current cooling system is more than adequate. My big HP LT motor runs hotter than I like during a race. Everybody and their brother can tune an LS, including me! My car sounds NIIIIIICE (classic V8 rumble) but the LS race cars just sound MEAN. Like nails across a chalkboard mean. If you haven't heard one youtube one of LG or Mike Skeen's in car videos and turn it up. A C4 with an LS has more value if I decide to sell it If I decide to put some money into the LS motor, I can keep it and swap it into the blue car next year and put the LS2 in the C4. Or, more importantly, if I ever have an issue with the C4 race car, the LS2 becomes a nice spare  I'm putting numbers together right now, but it looks like between $4000 - 5000 depending on how complete the LS core is I purchase. Quite frankly, I should be able to get at least $3000 out of my existing 383, maybe more. It could become a neutral cost swap. If I go through with the project I'll document the steps for a Guru tech article. However, it won't contain some of the critical info like how to make it work with the digidash for the street car crowd. There's a thread I started with some questions on CF if anyone is interested. |
