aamerh Posted September 1, 2008 Report Share Posted September 1, 2008 just wondering, did this ever happen? Link to comment Share on other sites More sharing options...
Jdubs99 Posted September 2, 2008 Report Share Posted September 2, 2008 I'm pretty sure it will eventually, just needs some donor parts and Ren's spare time. Link to comment Share on other sites More sharing options...
MazdaMomma Posted September 2, 2008 Report Share Posted September 2, 2008 I am highly interested in this particular mod... Ren, found anything as of yet? Link to comment Share on other sites More sharing options...
mts Posted September 3, 2008 Report Share Posted September 3, 2008 ... I have everything else done... HEY REN need a donor car? It might be possible... I can now afford the time to leave it with you... Link to comment Share on other sites More sharing options...

latinopikachu Posted September 3, 2008 Report Share Posted September 3, 2008 yes, a most excellent idea Link to comment Share on other sites More sharing options...
Renboy Posted September 3, 2008 Author Report Share Posted September 3, 2008 Sorry guys/gals/gays, I will not have any time in the foreseeable future. I will probably be quite absent from all car forums for a while. Details will be explained in the Water Cooler in the next couple of days. MTS, I still have those heads here for you.

mts Posted September 3, 2008 Report Share Posted September 3, 2008 I think I know what is going on... Anyhow, Ren I will be by maybe this weekend to get the heads... Sorry for the delinquency, been traveling like a damn fool. Link to comment Share on other sites More sharing options...

Sorry for the delinquency, been traveling like a damn fool. I won't be home this weekend, gone to Michigan. Will have to meet up some other time. Do you still have the muffler and the throttle body (milly 2.5)? How about a straight up trade, the heads for those two? I'll let you know when I have time.

Jdubs99 Posted September 5, 2008 Report Share Posted September 5, 2008 Ren has already described the process, just a matter of someone getting the cams and a way of getting past the ECU, probably best addressed with a completely adjustable unit and dyno. It's basically a matter of eliminating Miller for Otto. If Ren is correct, I question the ability of the tranny to handle the amount of power he is projecting. I'm about a year out from my Milly becoming a project car unfortunately, hopefully this theory can be tested by someone sooner. Link to comment Share on other sites More sharing options...

I have the muffler of a 2.5 milly that is just sitting here. If X-man doesn't want it, you are welcome to it. I still have it from when Gotta had the muffler replaced on my milly. I can send pics of the condition it is in to you if you want as well. Just let me know. Link to comment Share on other sites More sharing options...
Renboy Posted September 8, 2008 Author Report Share Posted September 8, 2008 Thanks for the offer MC, but I was talking about one of the two mufflers that mts scored a while back. I was supposed to take it off his hands but haven't had time to meet up with him. Link to comment Share on other sites More sharing options...

MURRAYBRYSON786 Posted April 9, 2009 Report Share Posted April 9, 2009 ok so i have an 95 S, but am wondering if this mod can be reversed to help our slower L brothers by ordering say the S cams and going super or turbo?just wondering and also i think it is way cool if i can't get my car figured out i will sell it for $1000 to this project ,95 millenia S gold tan interior(not the greatest of shape sorry) 4th owner Link to comment Share on other sites More sharing options...
SteveSter Posted April 9, 2009 Report Share Posted April 9, 2009 No these cams are specific to the Miller Cycle engine and work only on this engine. If you were to try to use them succesfully on a NA engine you would have created the Atkinson Cycle Engine which is more efficient but slower. Like the engine in the Toyota Prius.

Task514 Posted April 11, 2009 Report Share Posted April 11, 2009 instead of using KL cams... why not just reground the KJ cams to make the valves close earlier, thus turning it to otto cycle? Link to comment Share on other sites More sharing options...
SteveSter Posted April 11, 2009 Report Share Posted April 11, 2009 I think the KJ cams are so different they cant be reground to be similar to Otto Cycle cams. Either way I think the compression ratio would shoot up way to much for the engine to handle. Link to comment Share on other sites More sharing options...

SteveSter Posted April 11, 2009 Report Share Posted April 11, 2009 That is only static compression ratio, when you have forced induction effective compression changes completely IIRC. Link to comment Share on other sites More sharing options...
enginph Posted April 11, 2009 Report Share Posted April 11, 2009 That is only static compression ratio, when you have forced induction effective compression changes completely IIRC. We can call it the pressure at TDC. I dont know which one is important the absolute pressure or the compression. Link to comment Share on other sites More sharing options...
SteveSter Posted April 11, 2009 Report Share Posted April 11, 2009 I used to have a chart that would show you how compression changes depending on its static CR and PSI of boost. Cant find it anymore though. Link to comment Share on other sites More sharing options...

Either way I think the compression ratio would shoot up way to much for the engine to handle. How can it be so different. As far as I know, it is called miller cycle because the duration last longer. If you can reground the cams so to reduce duration until compression cycle occurs, it should be turned to otto-cycle. no? Link to comment Share on other sites More sharing options...
