Group install of Iso Thermal gasket

[dofu]

bump and subscribed for future reference...

[quote=cato]Removal of the upper Plenum required all the hoses around the throttle body to be disconnected. This was a real pain in the a** and does require two people to do it.

I held the upper Plenum out of the way without removing all the hoses. Used a piece of string and tied if off to the hood hinge. Worked good for me.

[cato]

Whatever works for you.... We thought it best to just remove the hoses. Live and learn!

thx...

Hey Cato. Did you notice a nice bump in performance?

[cato]

The spacer provided a really noticable bump in performance. The Iso-thermal gasket and coolant control valve adds nothing noticable so far.

Cool, thanks for the info.

How do you know Iso-thermal gasket and coolant control valve didn't do anything if they were installed at the same time?

Did you have one without it?

Cato and I already had the MD spacer installed when we both installed the iso thermal kit (gasket + CCV) on our G's. it does not give any immediate bump in performance, it just helps keep the upper plenum cooler

I also installed the Iso-thermal gasket and coolant control valve on my 2003.5 G35 Sedan over the holiday break. I already had the Crawford v5 plenum, Stillen hiflow intake, and 350z intake tube. While the theory of lowering the Plenum temps sounds good, the ‘butt dyno’ doesn’t measure much if any gains.

Was it worth the $70 to buy and the 5 hours it took for me to install? I guess that’s up to the owner.

Thanks for the excellent write up. I wish I had seen this post before I did my install.

is the 2005 coupe 5 AT or 6 MT?

if its 5AT did you feel any gains?

[tuan]

btw, i have an 05 AT and i recently installed my MD 5/16" iso thermal plenum spacer and the gains ARE noticeable. the car pulls much harder but dont expect it to pull like crazy becuase thats going the F/I route. and its well worth the money.

i got mine off of Dave at partshippers.com for a great price

hope this helps a little

ok i'll trust you on this.... cause if you are wrong... i will hunt you down... and say you were wrong

i got mine sitting here next to me.... just need to find time to install it.

[tuan]

haha, i highly doubt u'll have to hunt me down.

just remember to take ur time on the install and not over torque any of nuts

and btw i also did the overnight ECU reset by disconnecting the negative battery line. not sure if it helped but i think it might have. enjoy!

i've done mods before so i'm not scared. just dont wanna get stuck doing this just to find out i barely got any hp.

i dont see a point in reseting the ecu. we have obdII so whats the point, the computer will automatically learn the mods and adjust itself to be as close as possible to stock specs.
