Hey Guys,


I thought I would surprise everyone after I did the install...but looks like I hit a couple of snags already.

The Car : 1989 Camaro RS (2.8l)
The Engine: 2002 LS1 with 4L60E

Work so far...engine is in the car (so is the transmission...), I have been fiddling with the ECM ...

still wondering about

#1 We can't seem to get the v6 throttle cable to fit in the LS1 throttle-body , on the other hand I cant get the Ls1 cable to fit the v6...any idea's guys.

#2 We notched the frame and kept the A/c but ...can't seem to get the right connectors / hoses to go from LS1 A/c to the existing condenser.

#3 Have any of you managed to keep the LS1 cat's ...Right now I am thinking of deleting them (seems like a PITA to get them in)

#4 I found a LIM unit (VATS, O2, Tach calib, Fans, etc --> excellent unit) from bakerselectronix so I am keeping the tach...speedometer on the other hand is a completely new problem. Can I remove the VSS from the trans and put the speedometer cable there and hten hook up the VSS input to the VSS output from the speedometer (I think there is a VSS output in the back of the speedometer that was feeding my v6 computer...please correct me if I am wrong here.), can someone otherwise direct me to a cheaper unit than the TCI Speedo-control unit / the Cable-X , both of which convert VSS-> cable drive but are like 300 bucks each.

#5 We seem to be having a problem with the original torque arm fitting into the 4l60e (we kinda swapped the the other way and it fit perfectly ..is there a better way to do this?). is there a part # for a mount that would work right off?.

#6 I was under the impression that 2002 did not have a EGR but I seem to have one, and do I need to hookup the 89's Evap canister and all that crap?

can someone help me out here. I will post some pictures of my install as soon as I can get a camera. I am hoping to have the complete install done in a couple of days...

 

#1 is a known issue. Either get a 4th gen throttle cable and adapt it, or the Lokar piece with requires minor modification.

#3 I had no luck, the LS1 cats were up against my floorpan. I had Mufflex fab me a y-pipe and two aftermarket cats.

#4 no. If you do that, the PCM will have no VSS input. Either get an Abbott conversion box as you described, or adapt an aftermarket electronic speedo (Autometer, etc.) into your gauge pod.

#6: 2002 F-body had no EGR. If yours has EGR you probably got a '98-00 LS1.

The evap cannister is a good thing, it vents gas fumes from the tank and can be plumbed right into the LS1's existing purge valve.

Good luck finishing the swap, it's worth the trouble!

Thanx for your reply kevinc...

#4 I heard that the Speedo in my car has a VSS output that went into the 89 PCM ...can I route that into the LS1 pcm and adapt the tailhousing to take the cable drive?

#6 I verified the block # and VIN to come from a 2002 camaro Z28...???. maybe I am confusing a return line that goes into the intake as a valve. I will post some pictures soon.

 

I have a feeling that you might be seeing the Evap Selenoid stuff and mistaking it for EGR. Did you get the motor and everything in one big package? I have a 2000 LS1 block, but I deleted the EGR and I have a '02 wiring harness without the EGR hookups from the factory.

 

This is a shot of the Evap Selenoid on my car. I circled it. In this picture I hadnt connected it yet, you can still see the orange cap over where I would connect the hose. What I did was delete the Evap Canister or Charcoal Canister from our cars all together and I just ran the Evap line from our car up to the LS1's Evap Selenoid with some 5/16 rubber hose and using LS1 Edit, I changed it so the LS1s Selenoid was always on. Usually the LS1's PCM reads the tank pressure from the sensor on the 4th gen tank and then turn the selenoid on to vent the fumes, but our cars were different. I know a couple people that disabled the Evap stuff all together and they just let it all vent into the open air...

 

Oh one more thing I forgot. I vote for the Lokar throttle cable. Here is a shot of my motor with the cable... Looks good and its adjustable so you dont have to deal with trying to shorten the stock LS1s cable.

 

The older VSS output your '89 will generate isn't compatible to my knowledge. The VSS in the T56 trans generates something like 40K pulses/mile, can't recall offhand but it's not the same frequency. The LS1 PCM won't be able to use the input data.

EGR on the '98-00 F-cars is mounted on the pass side head up front, cylindrical shaped motor housing that routes exhaust gas from the pass side exhaust manifold to the top of the intake right behind the throttle body.

 

knyghtmare...thanx for the pictures ...looks real cool.

When you say LOKAR do you have a part # or something Lokar is a general name correct?

The baker electronix unit that I have has a fuel tank pressure sensor defeat wire to disable that signal so no prom programming is required. (man that LIM unit is impressive.)

Still waiting to get some fuel lines made and redone.

Why do I see a AFPR in your install (I know the LS1 does not have a return line ..how does that afpr work for ya).

 

You need the AFPR, or a fixed-pressure regulator of some kind, to regulate the pressure to the LS1 fuel rails and return the excess delivered fuel to the tank.

On the fourth gen cars it's done back at the rear of the car, and only a fuel feed line runs up front to the engine compartment.

Alternatively, you can use '97-98 Vette fuel rails if you want. They have a traditional feed/return line setup like the 3rd gen design, with a regulator on the rail.

For the Lokar cable, Lokar part# TC-1000LS1 is the one you want. Right length, only work you need to do is fitting it to your car's gas pedal.

thanx kevinc...Looks real neat...lot nice pictures for me to look at for reference

basically , We are going to see if we can make do w/o the fuel pressure regulator. my friend seems to have an idea...I am going to let him try it.

kevinc...what did you do about your speedometer?

 

on the back of the instrument cluster , the vss wire are coming out where the cable connects, NOT compatible with LS1 computer .

 

ok guys another problem...

The A/C lines


I kept the 4th gen A/c that came with the LS1 (notched the frame...) but the lines that came off the 4th gen LS1 are bad (crushed in one place...) does anyone know of a replacement that I can use ?

The third gen A/c Lines looks different on the compressor side.

 

Used a 98 Throttle Cable, but instead of shortening it (the cable)
I just took the gas pedal off and bent it a little bit so I'd have WOT. I had to take it on and off like 2x but it looks clean and not so out of place since it blends. It's been over a year now since I did it, so I don't remember all the details, but that's basically how it went.
Here's an old pic I gotta get some new ones
