Torque Specs on Intake Manifold?
I need to order a shop manual for my car but in the mean time does anyone know the torque specs on the intake manifold. I am installing a Crawford Upper Manifold on Thursday. Does anyone know where I can get a shop manual? Are there different types or is the dealership a good place to look? I know sometimes dealers don't sell them but everyone says that's the first thing one should buy before doing any major projects. Thanks for any help and yes I did search for these specs before asking, I promise! Thanks!

I think it's different for every company. My MD + Spacer torque for upper plenum was 100 ft/lbs.

100 ft-lbs?? NFW. Lug nuts only get 75 ft-lbs. That would strip the bolts rights out of the soft aluminum plenum. It's more like 110-120 in-lbs.
You can get the correct FSM for your model year from the Nissan website: http://www.nissan-techinfo.com/nissan/ Sign up for a one day access ($20) then download the manual(s), they are in PDF format. [Edit: Oops, wrong pic. Here's the correct one that shows all the plenum bolts. Torque is 9-10 ft-lbs or 108-120 in-lbs.] |
It's 100 inch lbs for the parameter bolts & 60 inch lbs for the 6 inner bolts..
Follow the tightening sequence listed above. |
Basically about as tight as you can get it with one hand at the top of the socket wrench (no lever arm torque)... I doubt it will leak - if it does you can try to tighten it further, but hand tight I found works just fine and for me equates to about 60-70 in-lbs of torque

I think it is called a “nut driver.” |
Thanks A lot everyone. I appreciate the link for the shop manual Dave! I'm installing a Crawford 1st gen. manifold tomorrow night. I hope to feel some gains! Thanks Again!
