1. Well I was driving my car yesterday and it was fine.. went for a little cruise and parked it.. about an hour later I decided to move it into my garage.. started the car and this HORRIBLE screech/rattle was coming from my engine.. I immediately shut off my car, waited 10 minutes and started it up again.. this time the screech was louder and the car was idling REALLY funny.. the rpm was around 1k and then the car stalled.. I started it up again and noticed smoke coming from the engine bay!!! I shut off the car and popped the hood and then there was smoke coming from the A/C compressor.. I watched it and it smoked for a good 10 minutes then *SNAP* the belt off the pulleys like melted/snapped off..

How would I go about fixing this? Where can I find the parts?

2. I think I have a boost problem at idle before the accident my car would idle around 1100 rpm and the boost would sit at 15 in of vacuum.. is that normal? When I would shift there would be like 25 inches of vacuum and it would stay there for a while when in gear. I have a 10-5-10 boost pattern...

would a good vacuum line job fix this?

3. When I shift I hear this horrible grinding sound the odd time but I push the clutch all the way down and it still grinds.. it does this every odd time..

How would I get rid of this?

4. There is this weird rattling coming from my A/C compressor / turbos. I don't know where to find the turbo control actuator.. (I know im noob, this is my first turbo car/ rotary so still trying to learn)

Can someone give me pictures?

5. Did the car come stock with dual oil coolers?




thanks!

 

p.s: I did search and I found similar topics on how people fixed it and everything but there really wasn't confirmed/in depth instructions for the fixes. Please help, I want to start ordering parts asap! thank you! and I want the cheapest possible ways with the best parts? like best quality thanks! and sorry for the double post.

 

some models came with duel oil coolers. you should be able to see easily if you have two.
there is proberbly nothing wrong with your vacuum lines if your car boosts properly.

 

Im not a rotary specialist yet but this is my best input knowing what I do about them. If anyone else dissagrees, please feel free to correct anything I may have disinformed.


#1 Your clutch on your ac compressor probably locked up, either get a new ac compressor, or delete the ac (to do so you may need to install an aftermarket pulley system). Best way to check is to grab the pulley where the belt would run and try to rotate it, it should move somewhat freely, if it does not then your clutch is definately locked up.

#2 -15 in vaccum idling is about normal (best of my knowlege), -25 in shouldn't be achieved unless engine braking. 10-5-10 isn't terrible if your running stock twins 10-8-10 is normal. 10-5-10 may be caused by insufficient spark, low fuel pressure, rich fuel/air mixture, and a vast amount of other possibilities. You may try resetting your ecu (disconnect battery and hold brake for 20-60 sec, reinstall battery cable and continue as normal if you still have stock ecu.

#3 If this is happening in only one or two gears and not all of them together I would say that one or more of your synchros are going bad/gone bad. It requires dissasembly of the tranny if so. If its happening through all gears your clutch may be adjusted incorrectly, or maybe your throwout bearing is bad.

#4 Grab a piece of vacuum hose and put it in your ear then use the other end as a stethascope to drown out other noises to pinpoint the noise you are hearing, just move the end not in your ear near the sound and figure out where it is the loudest.

#5 I do not have answer to, but if you search hard enough within the forums you should find the information you need.

 

ok thanks, found out that the clutch in the ac compressor was locked up.. will a USD air pump fit in an JDM car? where can I find a cheap, fast replacement? Thanks

 

5. If your 93 is an R1, it came with dual coolers.
