Yes should have read the sig huh??

I am leaning toward the 5.3 alum block for my swap. Should have even better
Balance.

 

Yeah Mike, we've been doing this awhile now. We've heard the "it will ruin the balance" more times than we care to recall. We've heard "you'll never get an independent suspension to hook" many times as well. When I hear these things I just go to my happy place........the view of the 2006 yellow Dodge Viper convertible getting smaller in my sideview mirror as I'm pulling him in 2nd gear.

 

How light can a V8 Miata get?? Is it possible to get one to 2300#'s ??

 

Probably.....I have a beefy crossmember/x-brace and an iron block and I'm 2500 lbs with about 6 gallons of fuel onboard.

 

Cool I wonder how much weight the Aluminum block V8 saves.. 30-40 #'s I would hope.

 

How much do you want to gut the car of creature comforts?

AC compressor, hoses & condensor
Depower power rack, pull PS pump & hoses
Gut inner door panels
Remove all sound deadening
Light racing seats
Soft top assembly

 

Yeah that is pretty much what I was thinking. Even thought about removing
The windows and all related hardware. Get rid of the emissions stuff too.

 

oops

 

I don't think I'd go so far as to pull the windows (if they are power, change to manual). The inner door panel assembly and trim weighs a lot; if you gut the inner door panel you get most of the weight out. Probably a good idea to add door bars (Hard dog or other mfg) when you gut the door panel; they tie in the rollbar assembly to the front of car and provide you with a lot more side impact protection than the stock door parts.

 

i weighed 2720 iron block,aluminum head with me and full tank. one step im taking since the front sub frame gets cut up........ im putting an 06 front sub frame and suspension in my 92. it uses uhss steel witch is thinner but stronger and aluminum control arms......the other bonus is it nets bigger brakes and five lug witch matches the mustang.........i dont know hom much lighter it is but when i pick up both assemblys its a big diff. carring it.
