It has 11mm flywheel bolts.
The heads are necessarily better on the roller cam engines. The intake ports are better but the exhaust ports are worse.




thanks for the flywheel bolt correction. getting engine management right could be handled by using a later PCM and DBW, GM got fairly standard with their crank and cam position stuff in the mid-late 2000's I would be very surprised if the OS used for an LS engine isn't the same as the later N*, or compatible. that being said, I haven't tried it. Unfortunately, that would require a re-wire, or at least all new connectors for the PCM.

The engine management can run the engine... that's no big.
BUT, all the ancillaries like clutch switch, VSS, AC request, speedometer output & cruise switches that are handled via the bus in the car the 58x ECM came from are handled by discretes in the Fiero. I'm going to end up with a CANBus I/O gateway to make those work.

My buddies LZ9/Getrag swap has an E67 and the VSS is input to the PCM, and a 4000PPM output runs the speedometer just like anything else. the E67 actually uses a clutch pedal position sensor IIRC. my buddy doesn't have one installed and the car seems to behave fine. I can't speak to the AC request, I would guess that it is only VIA serial line/CAN bus.

And cruise control... There are several choices that have one or two of those functions available, but only one that has all of them.

The only 58x V8 PCM that has all of the functions I mentioned is the SSR PCM, and it's $600+ since GM hardly built any of them.

Everything I'm seeing for the SSR is 24x, that being said, I didn't look very hard.

I wonder how much of that is software, and how much is hardware. There's a guy who has been advertising a marine based PCM on some of the 60V6 facebook pages that claims support for all sorts of stuff, (including DI!) but I haven't been able to find much out about it.

The E67 discrete inputs that work changes based on the OS and calibration. I don't think any E67 V8 calibration has a functioning discrete VSS input. All the auto calibrations route the VSS to the TCM first, then serial line/CAN bus to the ecm.

All the later model (2005/2006) SSR ecms are E40/24X. I swapped reluctor wheel and cam gear on my E67/58X LS4 so I could run it for all the discrete inputs, factory manual transmission calibration, and working factory cruise.
I sent one of my E40 ecms with a VIN# from a 2006 LS2/T65 SSR to Darth and had him load the factory OS/calibration to it.

While waiting on things for the motor, I had time to make the engine bay nicer. I neglected doing this before due to time constraints… I was going to sand down and paint it, but I came to discover some bondo.



After drilling out some rivets, I pulled the plate off. Well that’s just dandy. The PO did a pretty good job covering this up with bondo actually. I am not sure what would have caused these rust holes originally. I assume the PO was cutting the trunk out to run something.

I was gonna take the time and fix it of course. I had to cut out a lot of the bad areas and make it much smoother so we could weld a fresh plate down. The bottom hole was there before, but that was gonna get patched up too.


I started to go a bit crazy with the grinder and delete the cruise control brackets and extra little ones.


I’m ashamed that I even installed the oil filter housing in this shape.


But I cleaned it up this time.


I ended up redoing the water pump again. It was mostly clean but not shiny. I would end up sanding it all down and getting rid of casting marks, and then painting it nice.



Some progress on the trunk wall. Not yet done of course.


More scotch brite and grinding.


Sanding revealed more bondo! I sanded as much as I felt comfortable to reveal any rust holes and found nothing concerning. I think they were trying to patch these holes here. At one point there was body filler in them I popped out and I never got around to patching them until now. I’m not sure why there were holes here to begin with.

Wow, no need to give me more ideas! That looks great.
