That is remarkably similar to our LIM on the top end.



Looks to be an almost identical pattern for the ports. I would be it lines up just fine, and perhaps a tiny bit of machining on the LIM to port match and you're totally good to go.

Speed is all a matter of how big your wallet is and how fast you want to go is based on the size of your checkbook. Thinking outside the box, consider this: What if you replaced the OEM PCM with a standalone system that controlled all the factors we all bitch about. Yeah, it might not be emissions legal, so that leaves it out for the states with IM inspections unless you wanna be an outlaw. But then you have no limits on air/fuel ratio, timing, map/maf pressures, speed limiters, etc. If Mother Mopar doesn't want us messing with her box, we can try and find someone elses' to play with. Leave the OEM PCM in place for looks and to make sure your turn signals cancel at the right time, but leave the serious engine control to the box in the trunk, or wherever!

God bless you. :P

[dodgebob68]

Thank you. He has blessed me in many ways for which I am profoundly thankful.

Getting a stand along computer tow ork with the engine is not an issue. Getting the rest of the car to work with the standalone a computer (aka trans and bcm) is the issue I believe.

[CaptainMorgan]

I've looked into this a bit, and definitely have considered that option. I know it can be done.

This, but what I want to know is if you can piggyback a stand alone controller that runs the engine while the stock electronics keep the rest going. Obviously it's going to throw codes and lights because the ECM isn't getting the engine to do what it wants, but who cares. The question is just if it can work.

My biggest concern there is if the factory electronics need to be reading the same signal as the stand alone that you are piggybacking. I don't know what effect it would have on the signal voltages to connect them to two controllers. At worst I would think you'd have to add a bit of circuitry to duplicate the same signals to send to the factory ECM, but I'm not even convinced of how much of a problem this would be.

The other angle is to replace the electronics in the interior with your own custom setup. This happens a lot of crazy car builds. The LHSS just made his own custom gauge cluster to put in there. The trick is that most of the time that's done with a car using a manual transmission. Those electronics are what mandate factory pieces stay in place, or something very custom be designed and built to run the trans.

[dodgebob68]

I considered that too, you pretty much have to customize everything because the OEM pieces are going to be so far out of whack, you'd be in limp mode before you left the driveway. Unless you are really stuck on the V6 FWD configuration, if you're going to go to the time and expense of completely changing the entire wiring and electronic control structure of the vehicle, you might as well pull the sick six out and go V8 RWD. If someone were to swap the entire system out of a LX (and I mean everything-engine, trans, wiring, all the toys) then you could have a car that would operate pretty much as considered normal, that is, everything would work like its supposed to. But short of that, yes, I think it would be easier to make a standalone system operate the engine than try to piggyback anything onto the OEM PCM. After having struggled for months I'm still working the bugs out of my piggyback system. But then I'm just an old gearhead hillbilly motor builder, not a rocket scientist.

Anybody have link for the manifold setup?

[dodgebob68]

Shouldnt be hard to get, check JDMonline.com. The JDM is all Japanese parts
I see we are thinking of doing the plus up on the strokers...its that great minds hit on the same idea thing...wow.

That may help... I am still trying to figure it all out on my end. A friend of mine has a 300zx with aa VG30 which is 'supposed' to be similar to the upper manifold as a VQ35. Looks like it comes down to bolt holes lining up...

[flipfloptrep]

Looks like the LH cars from the years 02-04 can't benefit from this stroker project because their is no way to tune the engines after the crank installation. Think you can run a 01 PCM in a O2 trep and have no problems with autostick?

[SRT6INTREPID]

Technically, an 01 and lower LH "PCM" is called an ECU (Engine control unit), a TCM (transmission control module) being the other portion. Since its no longer one unit to be considered a PCM (powertrain control module).

You can convert either production run (98-01 and 02-04) to the other easily but it is a labor of love. Requires swapping all harnesses, engine, body and dash. Beyond that you have cam sprockets and flywheel swaps too do and other things like EGR valves (i'd delete it).

There is a write up on this since it incredibly hard to find later year 3.X motors.

[CaptainMorgan]

Yep, you basically have to take a donor car that is intact electrically and swap every single piece over. I could do it if I wanted to, I've swapped all the wiring already for M wiring (except engine harness, no need for what I did). I just don't see a strong need. The only real gain that would matter to me is if I found a 02 special PCM setup.

[flipfloptrep]

This could probably work. Couldn't find the write-up on this but if I got those same 1.2 cams that inertia is selling I could really do the needed tuning on my car if I switch to a later year ECU. Found out the 02 Prowler and 01 300M have the same ECU and you can take the rev limiter off the Prowler. Would I have to change the BCM and its wiring also?

[EagleESI]

Just throwing this out there, seeing it could be done. Easy solution to the whole computer deal and the whole FWD deal.


Prowler Drivetrain. Everything would work and if you got that much money just laying around can be done right with easy accessible parts (in relation to other major mods)
