Default Engine swap

Hello, I Know this question has been asked b4 but here goes. I have a 99 sw2 dohc that has a badly rotten rear unsafe to drive. I'm going to be getting a 97 sw2 dohc with a seized engine. I know that this swap is no problem. The 99 is out of state. I have a 01 sc2 with a dohc in it all 3 are automatics. Can I put the 01 into the 97? I know that I have to use the intake and exhaust manifolds from the 97. My question is the bolt pattern on the head the same

Your 97 intake/exhaust will NOT bolt up correctly. You can put the 01 engine in you'll just have to solder the connectors to match that style injector, pull the throttle cable from the 01 since it's different, and have an exhaust shop mate things up after the downpipe. Also probably keep the power steering and AC brackets to be sure.

Well that sucks. Story of my Life. The 01 is wrecked but good eng/trans. Also body except for the front. Looks like I'm going to be putting in the 99 engine. Just have to get in home w/o the rear breaking apart. You would think that the heads would be the same though all s series dohc

They changed in 99. Why couldn't you just use the 01 engine in your 97? It's not that hard of work to convert it

You'd need to take the intake and exhaust from the 01 and move it over to the 97. The 01 head will fit the 97 block; the blocks didn't change.

The other thing you have to consider is that the fuel system changed in 98; you'd have to account for that along with any sensors and sensor connectors that changed in the 01 head (and 01 block should you move it over as well).

The 99 and the 01 both have the narrow head design which was implemented for the 99 model year (transition year). You'd have to do the same for the 99 as well.

So I can keep both the 99 head and block together just put the 97 manifolds on it. Is this correct? The 99 was just rebuilt a couple of years ago. If I'm not mistaking both the 97 and 99 have the same intake manifold design

Here's the skinny, if I take the complete engine from the 99 ( with both intake and exhaust manifolds) into the 97 all should be good, right?

Cool Re: Engine swap

Ok I will use the complete 99. This is a fix for a rotten rear on the 99. I asked about the 01 because it's here and the front end of it is smashed. I didn't think that think that they changed this much THANKS

As I understand it the 97 manifolds (intake and exhaust) will not fit on the 99 to 02 heads. The 99 and the 01 should be the same. I don't see why you couldn't use the 01; it should be the same as the 99.

Either way you'll have to deal with the difference in fuel system though. It changed in 98.

Isn't the '01 intake manifold different? With respect to sensors seems like the '99 is a better candidate to have things plug in nicely.

A quick check on Ebay tells me that you're right. The 99 would avoid the threat of a cracked manifold coolant outlet too. 96-99 intake manifold is the same and is made of aluminum rather than plastic.

Default Re: Engine swap

If the '97 has a different fuel system, that would be the biggest pain. Hopefully you can remove the drag link bolt that holds the parking brake cable, so you can swap in the '99 filter/pressure regulator. But that is probably not too bad.

Edit - maybe that is not necessary. Just use the '97 fuel system. If needed I bet the '97 injectors would plug into the '99 manifold, or the '97 fuel line would plug into the '99 fuel rail.

Default Re: Engine swap

'91-'99 DOHC intake manifolds look the same but the way the fuel rail mounts change every few years. '95-'02 SOHC IM's should be the same as the '91-'99 DOHC IM's, probably with similar fuel rail mounting changes.

You'd have to compare the '97 & '99 IM gasket to see if you can fit the '97 IM to the '99 head.

'91-'97's use a return fuel system while '98-'02 use a return-less system, no idea how to hack it to work with the '99 rail if the '99 rail won't bolt to the '97 IM or the '97 IM won't bolt to the '99 head.

I have a 97 sw2 engine is seized. I have a 99 sw2 with a rebuilt engine,this car is rotten in the rear. I want to put the complete 99 engine into the 97. Let's forget about the 01 altogether. So what will have to be done? Fuel system? Front pipe? This is what I need help with. I appreciate all the help but I think that I may have muddied the waters. Sorry if I wasn't so clear. The 99 is my daughter's car now. The dam thing runs so good and mechanically there's nothing wrong with it everything works but the rear end by the drag link is basically gone no metal to weld to so the car has to go. Picked up the 97 basically for the body. This is what you might call a necessity job, not for fun and AGAIN Thank You thank you

Based on parts lookup the IM gasket is the same 91 - 99. The intake manifold is the same 95-99, made of aluminum. It changes in 2000 with the plastic intake manifold.

I think you have to use the 97 IM and fuel rail and the 99 exhaust manifold with modifications to the flex pipe assembly between the exhaust manifold and the catalytic converter. The orientation of the connection is different between the exhaust manifold and flex pipe assembly. The exhaust manifold changes in 99 and runs through to 2002 however the early 99 gasket is unique due to the addition mid year of the air injection system.

The alternator plug is different on the 99 so you have to either change the connector on the engine harness or use the 97 alternator. You may have to use some sensors from the 97 engine or change the connectors.

Thanks, I was going to use the alternator from the 97 . If I have to change the front pipe that's ok even if I have to change the fuel rail. I just have to get this done and I can't see wasting good parts

1997 is a change over year for the alternator.
If it's a early '97 with a build date in or before December '96 you'll have to either splice harness connectors or keep the alternator with the harness that you're keeping.
If it's a late '97 with a build date in January '97 or later then you don't have to worry about it.
