I'm doing the lnf lsj swap.. I have a 05 cobalt ss lsj with a built lsj zzp motor but Im in the process of swapping the lnf out of a 09 cobalt ss into my cobalt the engine any trans bolt right in when I bought the motor I got the engine trans (g85) engine harness, computer piping and intercooler, the problem I'm having is my harness don't fit into the computer for the turboed motor.. It's the harness that goes throu the firewall.. I was told I have to swap the entire body harness out along with a ton of other stuff!!!! My question is? What harness actually plugs into the computer on the lnf other than the engine harness and what all do u need to convert over, bc right now all I have is time and I'd like to get this car done

 

You need the whole cars wire harness.

 

why would you do a LNF swap if you have a built LSJ?

 

lsj>lnf because of the fueling problems

 

X2... jesus christ some people. lolol.

 

Have fun, you need every single harness for the car and the body control module. Then your radio and speedometer are not going to work. It's a mess

 

huh?

 

if ur gonna swap out the lnf, save the headache and put in something crazy like 2jz or ls1 or some crap like that, just convert it to rwd while ur at it

 

if your going for big power with a lnf it is very hard due to the direct port injection you wont get the fuel you need

 

So then how are these guys that have 400hp with a LNF getting the fuel they need to run their cars?

 

5th injector for those with huge power

 

thats funny because i witnessed matts lnf put down 698 i believe the number was this last weekend lol

 

I was going to say the same thing bro> But i just didnt know what kind of HP he was putting down

Thats why I just said with guys with 400HP

 

ive heard alot of people say that when you hit the 500hp mark with a lnf it falls flat on its face

 

u need to keep reading bro, lot of falling on the face issues been solved since those posts.
idk why op would even want anything past 500whp, even that is usless in fwd, unless u like runing slicks. all the time lol

 

Im bored haha I know it can be fixed figured I start something exciting but id still rather have an lsj

 

there is a guy trying to do this, we suggested on another site that this is a formidable task, one that is possible but highly unlikely to work. His project is not done. it doesnt run.
