Hi all, does anybody know if my engine and trans out of my 94 z28 a-4 will fit into a 93 ta that had an lt-1 before ??

 

Fuel lines connect in a different location. Could swap intake and fuel rails.

AIR pump mounted in a different location. 93 bolts to the frame, 94 bolts to the engine. Just leave off the 94 pump.

AIR connections are different. 93 combines the passenger side AIR and EGR in a single connection. 94 has an AIR connection added to the passenger side exhaust manifold. Keep your 93 manifolds.

Different connector on the IAC motor. Could swap throttle bodies.

94 tranny will be a 4L60E, requiring an interface with the PCM. 93 ECM does not control the 4L60 (non-electronic) tranny.

Won't use the MAF sensor from the 94.

Probably other differences, but that's all I could think of.

 

do you think it's worth it ? i'm going to delete my ac and is it possible to use my z28 pcm? oh the car is being sold to me for $300.

 

You could easily swap everything up to (and including) the heads.
The exhaust and intake manifolds are where you start to run into issues.
I had a 94 shortblock in my 93 for a while before I rebuilt the original motor into a 383.

The only difference other than what Fred listed is the location of the oil pressure sensor.
On a 93, it's just above the filter.
On a 94+, it's behind the intake manifold on a 90* elbow.

You can find used 93 parts relatively easily, speeddensity.org has them on a regular basis.
I see part-outs here from time to time as well.
Keep the PCM that went with the sensors/harness/fuel system/trans you plan on using.

 

The "early" 94's still had the oil pressure sensor above the filter. By the end of the year, they had moved it to the top of the block. He could end up with either fro a 94.

 

my lt1 engine has the oil pressure sensor on the back of the manifold, would'nt i need an air flow sensor since i'm going to use the 94 pcm ?


thanks on the reply's

 

You don't have to use a MAF with the 94 PCM, but since you've got the whole car you might as well.

 

You didn't say you were swapping in the 94 PCM. Yes, MAF with the 94 PCM, no MAF with the 93 ECM. Put that info up front in your question, to get the answers you need.

If you are using the 94 PCM you need a 94 harness, because of the differences in the injector wiring (94 sequential vs. 93 batch-fire), and it would include the connections for the MAF, the correct IAC connection and would interface with the 4L60E harness.

 

i should of mentioned, man it is more complicated then i thought i'll just start looking for a 94-95 camaro instead and pay a little more cash i want to be able to use my whole setup wich i'm familiar too thanks guy's, well mybe i should ask upto what year would i be ok ? 94-95 or 94-97 ?

your guys help is really apreciated, thanks again

 

I don't understand. I thought you had an entire 94 car to pull the engine from.

If so, what's complicated?

 

yes i do have the whole 94 car but the 93 car i want to buy has no engine.

 

So what's complicated? You take the engine and everything attached to it out of the 94 and put it in the 93.

 

yeah it's not complicated i just got a little scared it would'nt work, thanks fellas

now i got to see if the car is stil available since i took long to make up my mine..

thanks i apreciate it
