89 Camaro TBI to LS1/4L60E
Hi guys,
finally I started my swap last week.
This forum gave me good info and so my swap is staight forward, but at this point I have 2 questions:
When you did your swaps, which trans mounts did you use? The 4 Gen one or the 3. Gen one?
I ask this, because the 4. Gen one is a little bit thicker and the mountig screw to the crossmember is centered,
while the 3. Gen one is thinner and the screw is a little bit offset to the right...
The second question belongs tho the radiator... How did you made them fit? Mine has "nozzle" on the underside (passenger side)
that hits the frame, so it would sit aslant. Did you dril a hole???
I can provide pics later...
Cheers Robert

Re: 89 Camaro TBI to LS1/4L60E
I just see a 3rd gen trans mount and a modded 3rd gen trans crossmember. Auto trans.
for radiator I’m using the 3rd gen radioed. If you’re have problems with the drain hitting tyen it sounds like you probably need to drill a hole. I think that’s what you’re talking about anyway. I assume this is a 4th gen radiator and the drain is on the bottom instead of the side? if you drill a hole make sure to protect the bare metal.

Re: 89 Camaro TBI to LS1/4L60E
Thanks for your input with the 3.Gen mount.
And yes, I have to fabricate my own crossmember with a "tunnel" for the exhaust pipe from some 5mm steel.
because the swap crossmember from Hawks I ordered was 160 € waste of money, it doesen´t fit in any way.
I would love to keep my 3. Gen radiator, but how did you manage the size difference for the steam line connection?

Re: 89 Camaro TBI to LS1/4L60E
My steam Vent goes back in at the water pump.
You havent said what engine/trans you’re running. If it’s a truck engine and you’re using truck accessories you’ll need water pump spacers. My spacers were tapped for the fitting.
edit::: never mind I see ls1. Never mind the post

Re: 89 Camaro TBI to LS1/4L60E
But I´m still pretty unsure which radiator to go with..
The 4. Gen has the good steam vent connection, the 3. Gen fits a little better...

Re: 89 Camaro TBI to LS1/4L60E
He has relatively high milage (146k mls) but bought it very cheap so with the sale of all good parts, engine / trans and other stuff for the swap was free!

Re: 89 Camaro TBI to LS1/4L60E
Here are a few pics of what I have done so far...
Last week I was on vacation, so I had a little time to start my swap.
My good old TBI Nothing wrong with it, ran great but a little less power
Both cars next to each other
For the comfort I wanted to keep A/C (or at least to have the option later) I notched the K-Member:
Cut it...
...made some cardboard pattern...
...fabricated some metal pieces...
...did some spot-welding...
...complete welding...
...cleaning...
...some base coating...
... FINISHED

Re: 89 Camaro TBI to LS1/4L60E
As it is a 98 model, it still has a metal tank...
So no benefit for me to keep it, especially due to the different fuel-level-sending-unit.
So I had to change my old TBI pump to the LS1 pump:
98´ fuel tank
left LS1 - right TBI
removed the LS1 pump
replaced the TBI with the LS1 pump
oh yes, they have different connectors, so I had to solder the "new" connector to the "old" wireing and put it back in the tank.

Re: 89 Camaro TBI to LS1/4L60E
Then I reworked the fuel delivery.
I went the way with a late model Corvette C5 fuel filter, due to the built in regulator.
This scheme, provided by Pocket helped me a lot to get the right connectors:

Re: 89 Camaro TBI to LS1/4L60E
Also the hardlines from the 4.Gen doesn´t fit very well without massive bending.
It was no big Deal to modyfy the 3. Gen lines. A little bit cutting here and there... In the engine bay I bent the hardline a little upwards and used the original rubberhose with an AN6 adapter at the end for the LS connection.

Re: 89 Camaro TBI to LS1/4L60E
Oh, and pls don´t have a deep look on the engine... I´have never seen such a dirty motor!
Don´t know why the previous owner didn´t keep it a little bit cleaner.
As soon as everything is hooked up right and engine runs, I will take it out once again for cleaning.

Re: 89 Camaro TBI to LS1/4L60E
Your swap in the Camaro is coming along nicely. Keep up the good work. You're going to love the way your car feels with the LS1 engine. I know I did when I swapped in an LS1/ 6 Speed into my 1988 GTA.

Re: 89 Camaro TBI to LS1/4L60E
So after 4 weeks of not working on the car, here is the result of last saturday.
To keep the engine bay as clean as possible at the end, I did 4th Gen Cooling Reservoir swap.
Drilled the original welding points
Removed original battery panel
Fabricated some cardboard pattern
Made the metal counterpart
weld it in... (of course, I cleaned all the metal from rust etc before priming and welding)
and.... tataaaaa, its in

Re: 89 Camaro TBI to LS1/4L60E
Looking good
Just a detail, but Id swap those hose clamps on your fuel lines for fuel injection clamps. Those hose clamps are rated for a coolant system (14psi). LS fuel systems operate at 55-60psi and can spike to 75psi

Re: 89 Camaro TBI to LS1/4L60E
Time went by, doing nothing on the car due to some private things.
But since April I´m really busy and worked nearly every day in my garage.
Did all the wireing, looming, heater box back in, radiator mounting, trans cooler installation, PCM under dash mounting... and so on.
Here are some pics of the wireing...
So much wires
Labeled all of them
Tried to route them in the engine compartment
new, naked fuse box
assembling...
find the right location...
first try with the cable routing for PCM under dash mounting
a little tidied up
test fit the fuse box and power routing
Heater box in
Ready loomed

Re: 89 Camaro TBI to LS1/4L60E
The new Y-Pipe and modified headers:
All the header bolts broke, I had to shred some new threads for the studs
new studs in
removing AIR connection stuff
.
All the new pipes for the Y-Pipe
cutting the intermediate pipe
welding the 3" adapter in
new 200" Cats with collector
...
...
Y-pipe is ready to install...
installed :-)
ready for compete fusion

Re: 89 Camaro TBI to LS1/4L60E
And now I have a BIG problem, hope you guys can help me.
When I removed the PCM from the donor car, I flashed it.
Means, I deleated VATS, rear O2s, AIR and EVAP
As you can see in the vid, the car runs, but when it´s "cold" it starts very bad - 15sec until fireing.
Then it gets way to much fuel, runs mega rich and smells for fuel.
You cant rev it in a proper line, it always has breaks and swallows up.
Another curious thing is, the temp sensor reads 110° degree celsius in PCM, but my cluster gauge tells me normal temp.
I changed the sensor two times for new parts, nothing changed.
Do you have any ideas, or questions I can answer to you to get a better idea of my problem?
Here are two pics:
Thx Robert

Re: 89 Camaro TBI to LS1/4L60E - HELP too much fuel
Just to give some background...
I started my swap last autumn, before I pulled out the LS1 from the donor car (98 Camaro, all original) I took HPTuners to delete some codes.
By installing the engine in my 89 Camaro, I did the AC delete, EGR delete, AIR delete, rear O2 delete and EVAP delete.
My problems now are:
- The car starts very bad when it´s cold (10 - 15 sec). When it has run a few seconds and I start it again, it cranks over immediately
- The engine runs ok but not 100% calm. a little bit sloppy between 630 and 680 rpm.
- For my swap I had to use the 3-wire CTS sensor, one wire for the PCM, one wire for the cluster.
Here is a mysteria, because the sensor starts reading at 115degree, while the engine is cold. Within a few seconds the temp raises to 180degree, and after 4-5 minutes its at 230-250degree.
While the cluster gauge is showing normal temp.
- When I try to rev the engine, it doesn´t do this proper, it swallows up and does misfireing.
What I did:
- HPTuners AC delete, EGR delete, AIR delete, rear O2 delete and EVAP delete
- closed the AIR hole on the top of the intake
- welded all AIR and EGR holes in the headers
- closed the vacuum line at the back of the intake
- tried 3 different temp sensors, all the same result - much to high temp at the PCM
- measured the ohms at the cts sensors -> ok
- did a bypass cable directly from the sensor to the PCM -> same measurements / ok
- PCM has a constant power well over 13V at idle
- custom Y-Pype with 200" Cats
- 2 new O2 sensors
The car runs way too rich and when it turns from closed loop to open loop, it smells like fuel that it bites in your eyes.
Thanks for your help!

Re: 89 Camaro TBI to LS1/4L60E
Just to finish that...
It was a broken PCM and MAF... Upgraded to a 0411 99+
Car runs great now.
