I made an air dam
 

Here is the album.

Made from laminate flooring and PPP rivets.

Nice!

Nice match on the gay color.

Is that the original laminate backing color?

Beware of curb stops, not sure how much flex that material has.

Too stiff and it snaps/cracks, too flexible and it will not keep it's shape.

looks good!
the kicked out bottom will act like a splitter to get the air around the sides of the nose,and that will help with drag and lift issues of the forward slanting nose.

I painted the laminate gray. It has fake wood grain lines you can see if you get close. I have no idea how well it will do with curbs. It's kind of like a stiff rubber material.

I looked and was surprised to find the mr2 already basically has a full underbody tray, and the lower bumper directs air around the tires. My dam just extends the stock dam about four inches lower.

wow that looks pretty good man!
I had one of those before. pretty bad mpg for a small car. I think adjusting the cam timing alone could really help, considering that the engine makes a lot more high rpm power than low.

this page has a TON of 4AGE info.

I'm getting around 35mpg as far as I can tell right now. I think a regear would help the mpg a lot. Some of the other C52 transmission cars have lower ratio gearing.

thats not bad for one of those for sure. I have a 7aFE head laying around from a 7AC build i did for an 83 ae71.

I think that advancing the intake cam a few degrees could really help get the 4age sweet spot into the freeway rpm range. i know they make most of their power at 5000+ when you really rev them up.

i think the 4age LSA is around 116. even reducing it to 112 could make the engine operate more efficiently and with a more natural egr effect.

Very cool lip, it certainly changes the air flow. Bumper lips and diffusers are widely used in autosport, so it's proven with decades of racing.
