Chris83zxt Posted May 3, 2014 Share Posted May 3, 2014 (edited) So my car was running pretty great for about 2k miles on the setup below: http://forums.hybridz.org/topic/116315-my-ms3ms3x-full-sequential-sparkfuel-settings/ Unfortunately in late March we had a couple of very rainy days and I ran through a giant puddle and hydrolocked the motor. Even though I was able to get it restarted something is definitely broken inside the motor so it's been sitting since. I've been collecting parts and I'm about to take it into a local engine shop to have work done. I'm going to be going .030 over with the ITM flat-top pistons. Also I'll be having some mild head work done and a little bit of porting done on the turbo inlet. Some other miscellaneous stuff like a Fidanza flywheel to help pep things up a little. My compression will be going up to about 8.6:1. As you can see in the above timing tables I've got mildly aggressive timing in place (~40 degrees in a lot of spots). I figure I'll need to drop timing down and also boost at least during the break-in period on the new motor. Does anyone who has made similar modifications to their turbo motor have any suggestions on timing adjustment? I figured multiplying the entire table by .5 would probably be pretty safe but might be leaning too far on the side of safety. Any opinions are welcome and appreciated.

NewZed Posted May 3, 2014 Share Posted May 3, 2014 Hydro-locking bends connecting rods. Have you had the engine apart yet? You might need more than pistons. How can you collect parts if you don't know what you need? Curious on how that much water got in there. Did you not have an air filter?

Because I'm dropping it off at a shop and having a full rebuild done. I've got a spare block and spare p79 head if stock parts are needed (I intend to stay with a stock crank and connecting rod setup). I have a big cone filter that sits behind and beneath my driver's side headlight (pointing downward).

Chris83zxt Posted May 3, 2014 Author Share Posted May 3, 2014 (edited) I've been doing some research and after looking at a couple of N/A timing tables and reading some threads with people who have turbo'd NA motors I think I'll start with multiplying the bottom 4 rows by .85, the next four up by .825, the next four by .8, and the boosted areas by .66 I'm pretty confident that'll get me into a safe enough area until the motor is broken in enough for me to feel comfortable loading it up on a dyno.
