i have a 91 non turbo. my air pump bracket broke so i need to know if i can take it out + run without it.

 

yes, get a double alt. pulley and it will work just fine. a lot of people remove the air pump

 

do i need to clog the hoses?

 

Your car will be slower considering that s5s use the air pump to open the aux ports...

 

With the guy above ...........and................the catalytic converter, if installed, will clog up in the near future if you don't have a airpump and working ACV. Near term defined as within a year. That's just a guess on the time line.

About the hose. The one that fed air to the pump should be capped/plugged. The one that fed air to the ACV does not HAVE to be capped or plugged, but it's always a good idea to do so to keep FOD out. The ACV has zip to do with the running of the engine, except in a very minor way during deceleration when the anti afterburn valve in the ACV opens for a moment or two.

 

thanks for all your help so far.


so i took it for a drive + i noticed a few things....


first of it seems like the engine revs more freely now. its like the engine is freed up without the pump on there or something.

second thing i noticed is that it smokes constantly now. it was a bit worse when it started up cold, then never got better when it was all the way warm. it only used to smoke when it was cold.

i didn't drive it past 3.5k or so, so i don't know about how it would work when the aux ports should be opened.

 

I wouldn't recommend it. Yes, your car will run fine but your performance will suffer. Ive got a 90' GXL NA with minor mods and ran against a GTU NA with the air pump removed. We both have nearly the same mods but he got taken when we raced. Considering he even has the 4:30's I was thinking it was going to be closer than it was!

 

Right you took him because he 5th and 6th ports arent working more than likely or he has other problems....

 

yeah. so when i was trying to put my **** back together, another part broke :/


it started when the top bracket broke off for the air pump. i ended up taking that off + trying some JB weld on it as a temp fix. i was putting it back on tonight when the bolt i had for the power steering belt tensioner broke off. this sucks *** cause i have some toyo 245's on there. it broke once before + i had to drive around like that + parking sucked! so now i have the air pump back on + its loose as hell, but its on there. hopefully my part will come soon :/

 

Are you trying to tighten the the belt using the long tentioner bolt without loosening the tentioner pully bolt? That would explain y they keep snaping...

 

no. i loosened both bolts for the air pump. i think i just tightened it too much + its old... i have a habit of over tightening stuff
