Need overall advice on a 90LX vs. a 91 LX..... Looking for engine crank differences....as well as any other differences througout the car...
Thanks in advance

 

same exact car inside out - except the 90 had black door handles; 91 came with body color door handles.

as far as the crank, wish i knew more specifics on it. with a 90 you definitely run the risk of developing crank snout problems. it can be fixed however with welding or loctite depending on how bad it is.

i bought my 91 in December of 90....in other words, a VERY early 91 model. 218K, 3 timing belt changes - and no crank problems.

 

as he said, identical, pretty sure the crank snout was unchanged until 93 - 94.

I have owned mine since August 1990, no problems yet....

 

Wait there're a couple other differences. I just finished swaping my 90 lx into my 91 lx. I own a slightly crashed 90 lx and I'm throwing in the towel on her (found out that I had 30 p.s.i. in #2 cylinder & frame,fenders, and hood are tweaked.
Came across a 91 lx that had been salvaged. Clean shell, but interior and motor were done, front windshield was removed thus, it had a year or two of rain and weather beating down on the dash and all electrical under the hood. It took a week, but I stripped both cars COMPLETELY of every wire, harness, clip, everything! I'd done extensive mods to the interior in my 90 ( Kickpanels, door buildup's, sub enclosure for 10's and 12's).

Differences:
-Harnesses for the D and P door's same, except one clip.
-My 90 didn't have rear child safety latches in the doors, 91 does.

There's a few misc. other differences, but just thought I'd elucidate for the O.G. veterans of this forum.

There's knowledge and then there's experience. Learn by doing!

 

haha, didnt know about THOSE details......

 

thats a chitload of work dude, props to you.

But my 90 does infact have the childlocks on the rear doors....

 

Not sure when it happened, but it was definitely before that. My buddies '92 LX has the new crank design. I believe it was a running change made during the '91 model year (when they ran out of the old-style crank....much like the '94 piston change).

Oh, and my '90 (made 12/89, owned since 1/90) also has rear door child locks. Maybe it's a Canadian thing (the '90 without).

 

I'll check my 90 and 91 GT's tomorrow and see..

 

Thanks for all of your help so far guys....Keep the info coming if you find more.

(can't wait to get my new protege'---90' LX bad drivers side axel,needs slight brake work[told it needs a bleed job done], and a general tune up------it was posted in one of my local hardware store parking lots for sale $500 or best offer..... Getting the title on tuesday....YEAH)
