I've always been interested in how much weight savings, if any, will be had with an engine swap. Searching online can result in a wide spread of numbers, how factual they are is anybodies guess. I've been slowly putting together an LQ4/4L80 and have been dragging my feet until recently when the ol 1FZ decided to blow it's headgasket. So with the engine pulled, I bought a scale and got some numbers...
Fluids were drained from the toyota drivetrain and all accessories on both engines, I tried to keep things as scientific as possible. So if my math is correct, looks like i should have a savings of around 106 lbs!!
a442f from a 94Which transmission are you taking out/measuring?
I hope so too!!@DavidinAZ, I hope you have better luck with that intake manifold than I did, see post #945.
Oh that's cool. I totally don't need one of those scales, but I'll be ordering one soon lolI've always been interested in how much weight savings, if any, will be had with an engine swap.

Some of you might ask why not use the existing cruise on-off button to control the GM unit.. on the toyota it is a momentary switch that completes a second circuit to the cruise computer to tell it on or off. For GM a latching switch is used and it basically opens or closes the single cruise circuit including resistor ladder. I don't see a way to make the toyota on/off switch hold the position.. maybe someone else can?
You could use a latching relay with the Toyota momentary switch to do that job, if you wanted. What is Latching Relay? | FAQ | Singapore | Omron IA
That's actually an easy one to do. Just haven't got around to it. Need to put in a switch in parallel with the low range transfer case switch so it thinks it's in 4lo
