intake mani ????

[RB_Shaggs]

i see that people put the L16 intake mani on their L20's what is the gain cause i have a spare one and need to put my header on so i wanted to know if i should change the intake mani too?? any help appreciated..

There isn't a "Gain". You "Lose" the EGR port and on the '75-77 type lose the "Mated" Intake/Exhaust setup as well.

 

Of course, losing those is a "gain" in a way. It's a cleaner setup. The runners are smaller than the L20B intake ports on the L20B type heads, however.

You just hit them with a die grinder and make em bigger. I still have the EGR port on my L16 intake.

Hmm, I didn't think any L16 came with EGR...PVC, yes but no EGR...

PVC=good

EGR=bad

well after i put on my empi. i pretty much blocked off everything with plates or plugs and i am putting on my header to eliminate the rest of the stuff.. i ripped all the smog crap off and shaved like 40lbs off the truck... i just have a L16 manifold so just seeing if it was worth swapping..

The 'Gain" would be in the ease of installation and removal... some of those bolts are a pain in the ass...

You're right Paul, I was thinking PCV not EGR. I hate EGR valves! Mine on my '97 is giving me grief (check engine light) and they want $100 for a new one!

if you run your engine at low engine loads most of the time. the egr is always working so it will get clogged. just clean it out and see if the light goes away.

I pulled it out, sprayed some carb cleaner into it, didn't seem to help.

hey Shaggs, get rid of that old-skool mated stove-pipe bullshit and go with your L16 setup. It's not only a cleaner look, but it eliminate the need for making block-off plates and having smog connections on your exhaust mani. Hog your openings out to match the L20 if you're using a weber. I just replaced all my smog junk with the L16 intake and a header, I would strongly reccomend hooking up your brake booster vaccum line to the intake though, I blocked my EGR to elimate a vaccum leak, and instead of running a PCV into my intake, I got a used spare oil catch can from a friend(not because I really need it, but because I thought it looked cool and would be a functional alternative :D) That should take care of my crankcase ventilation. Just an idea if you can find a cheap one or if you know someone who's got one lyin around.
