getting ready to order spacer?

[mtdive]

well i was getting ready to order the spacer for my 06 g35 coupe. and im not sure what one i need. do i need the 5/16, 5/8, or 1/2 spacer. and do need the copper iso thermal spacer or just the iso thermal spacer or just the ragular spacer. and do i do the spacer first or do i wait i get the mrev2. and do both at the same time. or do i even need the mrev2

[tollboothwilley]

if you have the revup then you want to do the spacer & MREV2 at the same time

spacer doesn't really matter. 5/16 shows consistant gains across the rpm band, 1/2 & 5/8 show higher increases but minimal increases at low rpms.

i dont think the iso/copper spacers really change much, but thats jsut me

I went for the 5/16 ISO Therm

You may want to get the MREV2 at the same time...saves you tones of time later because you'll just have to remove everything again.

Nice gains with both these mods!

I recently installed my spacers and I was surprised at the gains. I got the Motordyne 5/16 iso thermal spacers. I read all about it before and put off installing it for a long time but I regret not installing it sooner. I suggest 5/16 spacers since you gain power in the lower rpm range. You'll notice the difference in everyday daily driving.

5/16 That way there will always be the option on the FSTB.

My FSTB should be here in a few days. I'll let you know how much modification it takes to make it fit with the 5/8's spacer.
