Swapping a 97 into a 94 GTP

[JakeMetz63]

How much extra work would a 97 LQ1 be to put into a 94, whats different and that type of stuff?

[1990lumina]

I think this should be in the Powertrain section....you mihgt get better response in there

[terryk2003]

i thought they quit making the LQ1 in 96?...maybe you're thinkin of a different engine :?

[Prospeeder]

nope, the cutlass had the Lq1 in 97, then it died for good

[Psych0matt]

I thought (I think bryan said it earlier this week in a thread) that no 97's got the 3.4?

[terryk2003]

I said no 97's got the LQ1...prospeeder, if you dont know...don't answer...the last year for the LQ1 in the cutlass was '96...'97 was the last year for the cutlass alltogether but they only got a 3100...

[JakeMetz63]

damn, meant to put this into the powertrain... must have clicked the wrong one.

[cutlassdude96]

Monte Carlo got the 3.4 in 97

[Prospeeder]

Yea, they did, the 3400 didnt come out untill 99, so it has to be the 3.4 dohc, according to KBB, and yes the cutlass did only get the 3100 in 97, i thought some1 here had a LQ1 97 cutlass, dont gotta be a little dickhead about it, jeese

And as to the original question, the '97 GTP had a supercharged engine, so it wouldn't be a direct swap anyway, but I believe there was a '97 Monte Z34, but I can't be sure.

[GnatGoSplat]

Moved to the proper section.

[5speedz34]

The 3.4 DOHC was made from 91-97.

 

91-97 Monte Carlo/Lumina's I think Lumina's lost it in '96?

91-96 Grand Prix's

91-96 Cutty's- Cutty's got the 3100 in '97

 

About putting it into your 94. People have swapped 94-95 motors into 91-93 cars using the older 91-93 style harness. I don't know anyone off the top of my head that has done a 96-97 swap into a 94-95 car. I would assume you could use your harness from the 94 and you would be set. There might be a few sensors that aren't used but thats it.

[Guest Anonymous]

You can defeinetly do it, like said a few sensors may not get hooked up though.

[5speedz34]

Ohh and didn't the 3400 come out in like '97 with the new minivans?

[GP1138]

Yeah, something like that. Actually, I had a junkyard wanting to sell me a 3400 intake from a '96 U-van. :shock:

[terryk2003]

sorry...i guess i forgot about the lumina's/montes...but i did know for sure the '97 GP's and '97 cutty's didnt get the LQ1...

 

oh...and sorry for being a dickhead :oops: ...just wanted to get my point accross

[Prospeeder]

its all good, i could have sworn the cuttys did, but even KBB says it didnt

Yes you can swap a 96-97 3.4 into a 94-95 car, but you will need to do the following.

 

First off, you will need the 96-97 exhaust manifolds and crossover. If possible, use your 94-95 intake manifolds, this will simplify things. If you can't, you can use the 97 intake manifolds, but it will require some work, so let me know whit year intakes you have. Most if not all of your harness connectors will plug into a sensor on the engine, you shouldn't have any left over if memory serves. The 96-97 alternator MIGHT be different than the 94-95s, I know the 91-93s are different. So you may need to use your 96 alt and mounting hardware, but it will plug right in. THe 96-97 exhaust manifolds will have ports for an AIR injection system. Your 95 car does not have this, therefore you will need to plug these off. There is a single, threaded hole in each manifold.

 

Other than this it should be a bolt in swap. THe only real difference in the two is the heads, cams, and timing belts, but those aren't an issue here.

97 does not have holes for AIR. My car is a 92, so without question OBD I. I used all new sensors for a 92 and put them in the appropriate spot on the 97 engine. Works fine not any more difficult than a direct drop in.

[terryk2003]

anyone else notice that the original poster never came back to this thread?...

You are incorrect.

 

Due to the higher compression of the 96-97 engines, EVERY 96-97 3.4 DOHC was equipped with an AIR injection system. Much like the AIR system on the 91-93 manual cars, it injects air via an electric pump mounted in the front passenger fender area, and directs the air through 2 5/8" lines, one leading to the front manifold, the other leading to the back. It differs from the 91-93 system in that it only has a single port to each manifold, whereas the 91-93 5-speeds had 3 ports on each manifold.

 

In order to swap your's you also needed to splice in the 96-97 alternator plug into your 92 harness, as they were different unless you somehow used the 92 alternator. You also had to leave some sensors unplugged, he should not have to do this, and might not have to mess with the alternator situation.

I have a 94 GTP thats got a totally stock engine except with a knock in the lower end. The 94-95 engines that I can find have like zillions of miles on them and I dont feel like spending money on one that im sure will work. So I have all the parts to make the 94 run, since it does run. Found my engine

[Aaron]

Yes it is possible, and isn't too difficult at all.

 

Good luck finding an engine.

I was just wondering if it was possible to do this swap because I thought someone was going to sell me a 97, but he turned out to be all talk. Still looking for an engine.

 

FWIW: Jay (xtremelumina92) has a '97 3.4 with less than 1000 on it.

 

A few months back there was a guy about an hour north of me, selling 3.4 crate motors for about 1400. IIRC the motor was a 94-95.

Allright you little dick, most the time you say shit and it doesn't bother me, but you sounding like a complete cock here is. Do you want me to go and take a picture so that I can show you there is no hole in my exhaust manifold? I had to do no modification to the exhaust to install it. I did this work myself. Just tell me where this hole is and I'll go snap a pic.
