trying to install fast 90/90 combo do i need any accerssory??

 

Make sure you swap the valley cover bolts with the ones that came with it. Or else you can crack it.

 

I ran this spring to keep tension on my FAST TB... Worked perfectly... and yes,, the shorter valley bolts will prevent you from cracking the bottom of the intake..

is that because of the sticking problem with the throttle blade?

I need to do the same with mine, I cannot tell if my foot is on the throttle or not because there is zero spring tension. I havnt had mine stick open yet but being a six speed car it sure makes driving a pain when you cant feel any tension on the throttle pedal.

If I could buy it over again I would go with the Nick williams unit.

 

If you buy a fast 90 intake make sure the you port it or get it ported if you don't do that you will really be disapointed in how much HP you make...the Nick Williams 90mm TB is the best TB bolt onto the fast 90 intake..
