  • ENGINE SWAP

    Ok guys I'm having to replace my motor (spun a rod bearing at 59K miles). Its for a 2002 SL2 dohc. What kinds of upgrades or mods should I do while I have the replacement engine out? This is my first time trying to mod a saturn even though its my 3rd one. Any help is appriciated.

      also do you have anything at all on it? i know you said its your first time trying to mod it, didn't know if you had something like an intake yet?

      if you have cash there's some stuff to be done, like a ported and polished head, cams, header, cat back exhaust. theres lots of other little crap you can do to make it a more fun car to drive.

        I've got about $1k to put into it. I'm wanting to keep it kinda mild as its a dd and I drive 60 miles round trip. Since I now have two complete motors I was considering doing the dual intake cam mod (and since its a 3 gen head no grinding envolved). And possibly taking the spare head and trying to port and polish it myself. I know the 3rd gen motors have a lot of extra pollution controls on them that also brings down the mpg as compared to the 2nd gen. Is it possible to remove some of that stuff to increase the mpg so I can have more power yet not compromise my mpg?

          If you have it apart the 2cam idea isn't bad, but for a better gain you may want to use performance cams.

            And use a 98 or earlier head that has bigger ports on it. Get an ACT clutch if you want, a CAI, rig up an MS after you get the new engine broken in on the PCM, and buy a 50 shot wet nitrous kit. That's pretty much all ya can do. If it is an auto switch to a manual.

            You can do the two intakes if you want but if you want to follow dreams advice you need some way to tune it for perf. cams such as an MS or Safc.

              eh, if you're doing an N/A build, stick with the head you got.

                for 1k assuming you already have the motor

                I'd go with shaving the head .040"
                SDA cams
                SAFCII
                Fidanza Flywheel
                full exhaust including header
                CAI

                You should be able to get that stuff for about 1k. If you don't have any weight reduction done with good tires it would prolly get you into the mid - low 15's. Or you can just do the rebuild and get some nitrous, exhaust and intake which would give you some better times but then you have to keep filling the bottle.

                  also, it doesn't pertain to the motor, but some lowering springs are nice to have. they make these cars much more fun to drive since they don't handle too great stock.

                  and yeh, go with an earlier head, like 96-98 to keep it OBD2 compatible. they flow a lot better.

                  pretty much what i plan to do in the summer:

                  Port and polished head
                  port intake mani slightly
                  new rings, gaskets, and seals.
                  maybe SAFCII

                    The only problem with going with a 96-98 head would be that the head on your car is set up for an air pump. This will set a DTC in the pcm if you don't have the air system working properly. I don't know about in FL, but where I live, you cannot pass emissions if the SES light is on in an OBDII car. Just something to keep in mind.

                            I already have a used replacement motor with 59K miles on it. It has the "sport" 5 speed. The county I live in did away with emissions tests about 7 years ago. I'm not wanting to put nitrous on it anytime soon. If you port and polish a 02 head will it flow as good a as 96-98 head? And no I haven't done any weight reduction (stock steel wheels [img]{SMILIES_PATH}/sad.gif[/img] ). My tires are almost new so I'm not really looking at replacing them anytime soon. Also does anyone have any suggestions as to where I can buy parts? I want to replace the motor mounts but can't find anything other then stock replacements.
