    Im a 22 year DSM vet. These cars ignited my passion for high performance vehicles and quarter mile racing. My first car was a 1990 FWD Eclipse GS-T that i owned back in 1997. From there, i bought and built a 92 GSX that went bottom 11s at around 126 mph back in 1999 and 2000. Ive since also owned a 95 GS-T and a blue 92 Laser RS AWD.

    All that said, i havent had a DSM for about 5 years now. I currently own a 2018 twin turbo 5.0 mustang that traps ~147-148 mph on 13 psi boost which has quenched my need for speed in recent years. Prior to the 18 Mustang, ive also had a 650whp GT500 and a TT 2014 5.0

    But............... it all changed last week when i stumbled upon title subject 1992 Plymouth Laser RS AWD. This damn thing is honestly the nicest DSM ill have ever had and it took me 20+ years to find it hahaha. It was owned by the original elderly couple who bought it from 1992 until 2017. I bought it off the 2nd owner who had it for the last 2 years. I was able to grab it for $2500 with current tags, a current smog check (California boo), and in good running condition.

    It feels like it's pulling timing at low speed before boost so i will dig into that and correct it, but overall it runs fantastic. Over the years i have (like most of us) stock piled endless parts for these cars. I could literally build 2 or 3 complete longblocks and 2 or 3 transmissions from the parts i have laying around.

    Plans for this car are a high 11/low 12 sec street bruiser that lives on e85. I would like to run a good amount of timing (21-23*) with e85 and 21-25 psi boost.

    Planned parts list for 375-400whp:

    --VRSF 1G FMIC kit
    --stock appearing billet 20g (i have the compressor cover and billet wheel sitting on my shelf).. just need to source a 16g in need of a rebuild, or machine my current 14b CHRA to accept the 20g wheel.
    --ECM link
    --EVO MAF
    --1200cc RC injectors. (i have these sitting on my shelf).
    --DW 340 pump
    --Aeromotive FPR run off of stock fuel rail


    That should be about it. If i missed something, please speak up! It's been a while since ive played with one of these.

    Always refreshing to see completely original cars out there. Good Luck I’m sure all of it will come right back
    But don’t forget the clutch!( I’m sure those seniors wouldn’t be using heavy pressure plates)

    holy hell, that laser is beautiful!

    i miss my old 94 awd laser. was near mint condition, like yours. only had 90,666 miles, when i bought her in 2013. my current 94, is sort of that car's offspring. we swapped everything that was left from my wreck (lady ran a red light in a jeep compass and i T-boned her going about 45)... and here we are now LOL

    Clutch!! yes... ill definitely have to add that to the list.

    What is a good clutch these days that is not so heavy it will cause my crank to take a walk? LOL

    Thanks.. this car is easily the nicest dsm ive had. I look forward to making it better. Not many lasers out there! They are hard to find and usually lighter cars than their Talon/Eclipse siblings.

    Any pics of your 90k mile Laser? Would love to see that one.

    aside from a few imperfections on the bumper, it was in amazing condition. bought it from a family that had just moved to las vegas from alaska. supposedly it was freshly rebuilt, but could not pass emissions. turned out it was not timed properly.

    3 days before that accident, some tweakers busted out my driver window and stole my cd player and tools... it was a bad week LOL

    It's so true. They are like the 1st must-have fix LOL.

    Im stoked on the EVO MAF. I plan to retro it to the stock 1G aircan and keep the engine bay looking as stock as possible.

    Might even pass on a FMIC and just upgrade the side mount with one of these that i modify to air to air. https://www.cxracing.com/liquid-to-air-intercooler-pump-water-to-air-intercooler/AWIC18

    Ordered 340lph fuel pump and a 2.5” flange so I can fab up some 3” exhaust.

    I’ll be running an evo3 o2 housing I found in my parts pile.....I guessed on the flange and got lucky.

    Pics to come

    A true DSMer can appreciate this. I’ve built more 4g63’s than I can remember so I know how important proper cam timing is on these cars.

    When I bought this car, it was down on power, felt like it was pulling timing. It’s 100% stock, so not a rocket, but still I felt it should have had more power.

    So I checked base timing. Was waaaaaaaaaay off and too far retarded. Fixed that but had to almost bottom out the CAS to get to 5* which got my mind spinning about cams.

    Anyway... finally got around to pulling the belt cover and found this bullshit. SMH... oh well. Looks like I got me a little project tonight LOL!

    Got cam timing corrected and car is good. Installed new gates OEM style timing belt while I was in there.

    Since I’ve had it, the car has had a small intermittent miss at idle. On throttle it cleans up but very light throttle and idle, it’ll miss.... almost as if one cylinder has very weak compression. Odd because they all test at 145-155 psi so I knew that wasn’t the case.

    Installed new plugs, wires, and cleaned throttle body and installed new TB gaskets. Set base timing and idle. Still missed at idle.

    I tossed in a set of spare 450cc injectors I had laying around and boom... problem solved. Car now has a great idle right at 750 rpm.


    Also got a new OEM spark plug cover.
