300zx Aero mods
 

Today I made a few tweaks to my 1990 300zx

1. delete rear wiper, pulled motor and arm, popped in a flush mount plug

2. upper grill block with plastic sheet, to replace the vinyl I has on as a test.

I will post pics in the next few days, looks a lot smoother.

Sounds good. Have you noticed any improvements in MPG yet?

These sorts of threads need pictures! :)

And fuel logs!

I haven't driven more than a few miles yet with these mods, and I haven't kept fuel logs.

man, hope it's still stock under the hood, because it might get super hot (assuming you got the twin turbo version) :)

Shame on you! :p

Seriously though, without keeping fuel logs you'll have no way of knowing if things help or hurt. Its really a necessity.

It's a non-turbo, 3.0L V6, only mods are Air intake and exhaust. I had it taped up all last summer, the only time I saw the temp rise a bit was sitting in traffic on a hot day for 15 min without moving, once I got past the jam it cooled right down again.

Nice. :thumbup:
I just have this urge to pop in a little 3-4 cylinder engine and crop the front end back a bit...

I don't think you'd want to drive one of those with a 3-4cyl, it's a heavy car.

I think the 300zx starts out with an amazingly low cD. The shape is just about perfect. Still looks up to date too, 20 years later!

After seeing the sticker on your fuel door, I thought the punch line was going to be: it's electric!

(Isn't that a plug icon?)

cD is 0.32

The boxy 80s one was lower.. 0.30
Weird.

i guess the cd depends a lot with the front bumper... somebody got a wind tunnel here ? :D

anyway, the 300ZX is 1,7 tons, so it's pretty heavy (but still, a friend of mine got one, twin-turbo, 450hp, and does 18-19mpg (okay that's not super great, but considering the engine, the output, it is ^^)

Will you try lightweight rims ? you can save a lot (if you remain calm on the pedal :D) if you do a lot if city-driving - start n' stop.

well, the electric plug sticker is a bit is wishful thinking, i'd like convert it eventually. I also like the funny looks I get while driving, lots of double takes. It's showing my support of EVs. :)

I think of keeping my stock 16" wheels as the lightweight alternative to "upgraded" 17 or 18" wheels. I have thought about low rolling resistance tires. I also think the salt flat racer moon disks would be bad a**, to give it the retro future concept car look

love these. my buddy is building one for 900whp right now.

go to Home Depot and grab some garden liner and make a nice lip for the front

There is something even better at Home Depot-- the foam garage door seal. It would jut out a bit and form a lip, but unlike the hard plastic garden liner it won't damage the bumper when it scrapes

The moon caps are too retro to look good on a futuristic car like that. The moon caps are Buck Rogers-esque, but the 300zx is the style of Star Trek TNG and DS9.
Now flat pizza pans painted white...

good call never thought bout that since I see a lot of cars with the liner
