It’s an updated recreation from one I did way back in August, back when I trusted thevettenet more than automobile-catalog (for corvette engines). Both sites agree on the power, torque, peaks and even the redline, however they disagree on compression. I honestly have no idea which site is telling the truth, but the game doesn’t allow a 10.25 compression ratio so for now I’m going with thevettenet.
Some would say this recreation makes half a horsepower less than it should, I say 33.5 rounds up to 34 and therefore it’s exact. It should be noted however that Wikipedia claims this engine has aluminum cylinder heads, which if true would imply the other members of it’s engine family dating all the way back to 1947 also had aluminum cylinder heads.
This is an all aluminum engine according to wikipedia, and considering the B1B I uploaded 2 weeks ago was meant to have aluminum cylinder heads I’d say the developers really need to reconsider what tech year to introduce aluminum. Apparently America’s big three switched to aluminum in 1962 however were forced to go back to iron the following year by unions, 1970 sure is beginning to seem very late to introduce aluminum isn’t it?
Moving on I got the specs from automobile-catalog and the name from wikipedia as normal, wikipedia claims this engine is only in the 503 and 3.2 Super while these specs came from a preproduction 507. Power is right however torque is meant to be flat between two and four thousand revs and that’s certainly not true of my recreation. 1955 BMW M503 1Rev0.lua (36.7 KB)
Hi there, this is my first try, I hope you will like it!
This is a FIRE (Fully Integrated Robotized Engine), a very popular kind of engine here in Italy. This engine family was extremely famous during the latter 80s and the 90s, and some models (even if a bit “revamped”) are still produced today. The FIRE engines are very cheap, very simple and extremely reliable; they’re obviously not so powerful, but they are pretty torquey considering their small displacement and simplicity.
For my first creation I’ve chosen the FIRE 750 version; it’s pretty famous in Italy because is was one of the first engine equipped by the 1st generation FIAT Panda, a worldwide famous city car. Here’s the real-one specs:
-displacement: 770 ccm (yup, even if it’s called “750”, it’s a 770 ccm engine!)
-power: 34 hp @ 5250 rpm
-torque: 53 Nm @ 3300 rpm
-valvetrain: 8v OHC
-fuel system: single-body carburetor
-fuel used: regular leaded (in Italy it was around 95 RON, just like our current regular unleaded)
This is my Automation replica, I hope you will like it
My Results:
Power: 87.9 @ 5600
Torque: (89.1 lb·ft@4000

What was I thinking? Not as in me who’s typing, but other me who owns this account? He didn’t even try recreating the HSV LS3 properly, he just downgraded my corvette spec LS3 recreation and called it a day. Well, I Bruce who made 90% or more of the recreations posted by this account apologize for that video and present a proper HSV LS3 recreation.

Peaks come at the right place, however it’s missing half a horsepower although that could be because it’s missing half a mm of bore diameter.2008 Holden LS3 (R8)Rev0.lua (41.5 KB)
Now one in-actuate aspect of this recreation is it’s using forged pistons while the real thing uses hypereutectic, I did this because I wanted those production units to come down (from over 100) so it becomes more competitive against the equivalent FPV engine which I may upload here soon.
can i make a request, if yes, id like the engine from the chevy trailblazer, more specifically the 2006 model ls, and this is what i got from wikipedia: 273 hp (204 kW) 277 lb·ft (376 N·m) all-aluminum 4.2 L “Atlas” LL8 inline-six engine, im requesting this since this is the car im getting once i get a license, and no i wont request the SS engine, i think u guys made it already, its only an 05-07 LS2, and if no, tell me why
2005 Chevy LL8Rev0.lua (42.5 KB)I highly doubt the real thing has light weight forged pistons, but anything less isn’t up for the task without extra quality which just goes to show how needed individual quality sliders for bottom end parts are. If I had to guess what pistons the real thing has, I’d say hypereutectic.
I also don’t know what fuel it runs on, I got it working on regular however it would start knocking if you changed the pistons to cast.

oh thank you for the fast work corvette, and from my stepfather owning one i can confirm it runs on regular unleaded, i have no clue on the internals but if it is cast id accept your excuse
I managed to get it a little closer and run on regular with cast pistons. If the real thing has headers more like the tubular style ones in the game then please let me know and I’ll try redoing it with them.
ill hae tocheck next time were under the hood, google isnt being too helpful, also i put in a cast crank and it works fine with no major differences, just -2 smoothness
