i read the swap guide

[lowwSC2]

and about a million other threads. im not used to these lil cars. im wantin a 00-02 motor in my 98 dual overhead sc2 5spd. can i get away with the stock trans and ecu with minimul mods? any major stuff i need to do? its just a daily driver and i want a lower miles motor for it. whats the thoughts on putting an 00-02 ecu and wireing harness in a 98? what all will i need?

Can I ask why are you wantin' a '00-'02 engine in a '98? They were not a better desing, and they are bogged down with an AIR pump. The tranny will work no problem, but the PCM is a different story, I'm quite certain it won't. Along with that, the head is a different design and the intake and exahust manifolds need to be carried over with the newer engine. I think those are the major issues for you. Low Saturn is the expert in...well just about everything mechanical about hese cars, and especially engine sawps.

cant find a low miles 98. i threw a rod at 160K about a month after i bought the car. and all 98s i found were 100-150k and i just need something reliable. and something i wont have to keep throwing money at

If it's just a rod, you could find a bottom end, since pretty much all of the changes were to the head after 1999. That's if you trust your head. Maybe a newer bottom end and a mild rework of the head? Might be easier than swapping the whole thing, depending how good you are around motors.

id rather go with the whole motor im just now getting into the economy car scene. (gas prices) im more of a ford small block guy.

Tranny should work no problem. '98-2002 are all the same trannies. PCM...i think that will work also. the manifolds switched in '99 so you can use your '98 manifolds. and you will have to use your '98 fuel rail. other than that, it really should be plug and play

That means he can't use his manifolds.

forgot the "t".

you can not use the '98 manifolds

would i need a motor out of a manual car? or would an auto car work too? i heard the fly wheels were different. mines a manual

An engine from an auto would work, just remove the flexplate and install your flywheel.

This is what I did. I installed a 2002 block into my 1997 SC2. Mine had spun a bearing. The 2002 block was from a car with an auto transmission. The head, timing set, transmission and all bolt ons were 1997. I wanted the newer block because I had read here on SaturnFans that the ring design was better, used less oil, and the crankshaft was somehow stronger.

The transmission doesn't matter, just make sure the PCM is for the powertrain combo you end up with.

do yall know how i can get ahold of someone who has done the swap. the pcm is my biggest concern at the moment. arent they manufactored by different companys?

like a repair shop?

For the PCM i suggest keeping the '98 PCM. Keep the 5spd tranny and just drop the new engine in.

more then anough member here have done engine swaps. LowSaturn is the swap master haha

My 2000 SC2 didn't come with the AIR pump. But with that said it has a header on it so the previous owner may have removed that stuff when they put the header on. I've never had any SES light or driveabilty issues so apparently it can run without that stuff.

There shouldn't be any driveability problems, it's just emissions control. Are you sure your SES light works? Does it light up at start up? I didn't know it was possible to run without it, if your SES light works, I wonder how they got around the AIR pump. Maybe an older PCM?

Yes, my SES works fine. I could be wrong, but I always thought pre-2000 Saturns had the PCM mounted in the cabin. Anyways, I looked at my emissions tag on the radiator support. It says the car meets U.S. EPA emissions standards (not California standards like 2001-2002). The vacuum diagram on the sticker does not have the AIR pump in it so I don't think it came with one at all.
