Nothing in the interior "must" change to run the LS4 besides adding the electronic throttle pedal. You can add as much from the donor car as you would like, but it isn't a requirement for the swap. For now my fiero interior will remain stockish. A longer term project is to swap out the dash from a 1999 maxima (my wifes car and I like the dash). |

its not like the ecotec where you have to have the chipped key? and you don't need main display?

You do have to get past the pass key security, but you do not need the main display. I will probably add light to let me know when it is in 4cyl mode.

I honestly haven't decided exactly what I'm going to do for mine yet. I want to build a full custom dash, including custom LED gauge displays, but to start with I'll probably use the G8 gauges, and make any necessary custom housing to mount them in the stock Fiero dash.

Exhaust is done back to the muffler. Need the Mera specific tips before I can finish the exhaust.
Here is the fit for the rear merge section between both tubes before welding:
Finished building every AN/braided stainless hose:
So moved on to the wiring... The blue tape at the AN fitting will ensure proper length to the 500 connector.
The same goes for the blue tape by the VSS for the harness that goes to the ingnition box for the proflow system:
While the engine was in, I made this little template to locate the bulkhead connector on the harness:
Still need to POR the engine bay, finish the harness, finish the exhaust and then put it all back in to make some noise!

With all those upgrades on the ls4, what do you think your HP is at the crank? I just got one and was looking to get close to 400 at the crank. Did some searching, but still unsure of what mods to do before the motor goes in. [This message has been edited by iluvsd619 (edited 09-15-2011).]

I think the biggest problem you're going to run into, is the AFM lifters, and springs if you're using stock on those too.

DoD lifters are stock, but the springs came with the cam kit. Remember, this cam was specifically designed for DoD engines, so the lifters should last a while, especially since it will start out with the lifters locked until I can get DoD to work with the manual. The other LS4 guy running the same cam in his DD with functional DoD hasn't had any lifter issues and he is nearing 2 years since his install.
But yes, the DoD lifters are definitely the weak link. Once the thing is running I am planning to do some MPG comparisons and see what benefit DoD has for my application. Depending on what that shows me, I might purge the DoD hardware and upgrade to the VVT hardware and play with it.
