My 87 Camaro LS1/T56 Swap
I recently got a hold of a LS1 and T56 and most other goodies out of the 4th gen (99 camaro)
I will post my progress here as I go along. Im planning on starting the swap early spring so basically now im just trying to get all the info I can on it so i can prepare by getting everything i need to do it right the first time.
I've searched and gone throughtthe guides and im am basically asking if there is anything I should know that isnt normally covered in the guides and pointer from members who have done it.
I'll make a list of parts i have and parts i know i still need later.
thanks.

Your list of parts would be helpful, along with what you intend to keep (AC, PS, 3rd gen pedals/hydraulics, etc.).

Sounds pretty good.
You'll need a throttle cable as well. If the '99 doesn't have traction control, you should be able to use its cable.
Were you going to use the LS1 exhaust manifolds, or get headers? The '99 exhaust system won't fit a 3rd gen.

I meant the exhaust after the manifolds to the cat. Sorry, should have been more specific.

Re: Upcoming LS1/T56 Swap
i have a question regarding the pedals/hydraulics. Can i just use my 3rd gen pedals and T5 master cyl? or is it better/easier to swap the 4th gen pedals and T56 master cyl in?
also if i use the 4th gen pedals can i use its gas pedal of do i have to cut it off?
and how well do the 4th gen fuel lines work?

Yes
0411 PCMs are the most universally sought after service number and work with 99-04 LS1 harnesses

According to shr00m, the 4th gen fuel lines are compatible, but why bother? Diagrams and pictures of how to modify and reuse most of the 3rd gen lines are readily available on the forum

Re: Upcoming LS1/T56 Swap
I used the 4th gen lines because it was easy to swap out, but I also had a v6....
Also use the master slave cylinder from the 4th gen. From what I have read sometimes the 3rd gen does not apply enough force for the clutch to engage.
When putting in the LS1 and T56, it takes a lot of persuasion but it does eventually go in and fits like a (snug) glove. Make sure to have PB blaster for those stubborn bolts. Print all wiring schematics. Team third gen helped a lot with there walkthroughs.
Make sure the VATS is tuned out and the PCM has been tuned for the codes that need to be deleted or your engine will not run properly and you will spend crazy amounts of time chasing a ghost.
Make sure wiring is properly installed and away from any heat source.
There are a lot of little things that go wrong in every project but just keep at it and make sure when you throw a wrench its in the opposite direction of your car!!
I finally am getting mine out of the shop and cant wait to drive it! From what I hear its worth it all in the end when you see the look of your first victim!!
We should meet up once you are done since you live close....
Good Luck!

So i can just use the 4th gen master cyl on the 3rd gen pedals by just replacing that little pin on the clutch pedal with the 4th gen pin.
Are the 4th gen fuel lines a direct swap?
I know I have to get the PCM tuned (Get rid of VATS, CAGS, rear o2's, AIR, EGR, etc) since you are close where did you get that done? Or am I just going to have to sent my PCM out for a tune?
Meeting up sounds cool tho im not going to even start working on it till the weather warms up and me and some people started a car club over the summer so we are always looking for members near us.
I am also interested in making it speed density and removing the MAF. Is that just done it the tune as well?

Re: Upcoming LS1/T56 Swap
SD swap requires a tune. Do yourself a favor and leave the MAF wiring hidden somewhere in case you decide to switch back

Re: Upcoming LS1/T56 Swap
I think im going to ask you about anything electrical related, you seem to know it quite well.
Anyway how is the wiring from the PCM to the 99 gauge cluster? Reason Im asking is that I intend on using the 99 cluster since I have a 95 firebird dash and I know it just bolts in and the connector just clips in as well.
From what I've read the t5 master does not push enough fluid

Measure the length with the tensioner pulled using a string or tailors tape. Belt PNs generally correspond to their length and rib count

Re: Upcoming LS1/T56 Swap
things got slowed down a bit so its going to be another week or so till I get the engine.
Anyway i have a quick question about sensors.
What sensors can i get rid of?
What sensors do i need to keep?
I've decided to keep the MAF on and I am also using the 99 camaro gauge cluster

Keep pretty much all of the sensors
Rear O2s, oil level, coolant level etc small things can go

Re: Upcoming LS1/T56 Swap
Got the wiring and seats all out...now the fun part of wiring begins
I will be using the LS1 gauge cluster since I have already done a 4th gen firebird dash swap and it will bolt right in.
I took the wiring from the PCM to the dash as well as the wiring from the dash and PCM to the gas tank.

Re: My LS1/T56 Swap
Nothing was really wrong with it from what I could see, it did nook like its been hit on the passenger side in the front though.
The owner is turning it into a glorified track car and I really don't know what engine/trans set up he is going to go with. I gave him a 350 SBC 4 bolt main I had sitting around lol.
It really is a shame to tear it apart I guess. I even drove it from his house to mine which is like 40 miles and it drove just fine. But way I'm happy that I'm finally able to get an LS1 for my car and thats what I've always wanted to do with it so I can't complain lol.

Re: My LS1/T56 Swap
And now THE FUN PART...WIRING.
Its a pain but its not as bad as I thought it would be. Getting the conduit and tape off SUCKS, its sticky and not fun wo work with at all. I got a bunch of 5 - 10 pin connectors that im going to use to make it so i can just plug stuff in when i install it.
Anyway im not done with the harness yet but its getting there.

Re: My LS1/T56 Swap
I have a question on the PCM pinouts
The PCM in the 99 camaro i pulled everything from is a 9354896
The PCM from the 2001 vette i am using 12200411
I looked up the pinouts for both cars and they are different.
My question is will i have to re-pin the PCM connectors or can that be changed in the tune?
Also is there anything else i should be worried about as far as the harness goes?

Re: My 87 Camaro LS1/T56 Swap
Set your pinout to the 99-02 Fbody. Corvettes used a few minor functions the Fbody's didnt and also had DBW
If you compare the critical circuits like crank, cam, coils, injectors etc you will see they are identical

You need to flash a Fbody tune in the PCM
From a wiring standpoint, it needs to be made into a Fbody harness

Sender is signal and ground. Pump is power and ground. Grounds can be spliced together for a 3 wire hookup like the 3rd gen had

No, but they need to be tuned out of the PCM.
Leave the evap hardware on the tank and it'll still provide the fumes and venting functions.
