yeah i am torn between that and a HKS Hi power exhaust...the wife is chippin in 500 bucks for christmas...other mods that i have are ACT clutch,flywheel and injen cold air..the cosworth and the exhaust are around the same price and i want to get the best part for my cash
Get the Motordyne 3/8 or 1/2" spacer. . .cosworth is not worth the money and wait.
I have the cosworth on my 04 G right now and I'll be going back to the MD spacer next month.
The cosworth looks nice, sounds great but isn't worth it. The bracket on the right end cap broke off during driving. . .not really what you want on a $1200 piece. . .
I'll go take a pic right now


something that can be easily remedied but still. . .

yep, both in performance and sound (hear the engines sexy growl). . .combine that with a z-tube and you're set

*edit* just saw your list of mods. ..

lol yeah i didn't see that you were driving a z, i'm used to the G forums sorry. . .your factory intake tube is an upgrade to the G35 OEM piece. . .

you should do that. . .get the exhaust, y-pipe and spacer all in one!
a lot of people are getting the 3/8" because that's focused for more usable power across the board i.e. daily driver. . .
1/2 is more for higher rpm's. ..

If you drive a Z, I always recommend the 5/16" because it allows you to keep the strut bar.
The 1/2" spacer makes more top end gain but the 5/16" makes a better average gain.(and it lets you keep the stock strut bar.)
We used to make a 3/8" spacer a few years back but the 5/16" is a little better optimized.

I just put the spacer in my car. I've noticed a huge difference. I finally got over 160, and I can tell by the pull off the line. Also, the car pulls a lot more, and it makes the exhaust sound a lot better!
