I used a Dodge Dana 60 in the Solid Axle Swap on my Suburban. I replaced the passenger axel tube to get rid of the CAD unit and replaced the axles with Moser Axles. I kept the unit bearings becasue I have ABS on my truck and I wanted to keep the ABS functional. I modified the factory 4-link...
First question is which ECM are you running? Single wire O2 sensors will not work in the collectors (if long tube headers). What fuel pressure ar e you running? If you have it in the collector I would swap to a 3 or 4 wire O2, it's an easy swap. I don't like the heater running while the engine...
It's not that bad I ran the dimensions through a CADD program and then through a 4-link calulator just to make sure I wasn't shooting myself in the foot. Then I made chalk lines under the truck just make sure everything lined up (then sprayed clear paint over them so that they wouldn't rubb off...
My 1997 Suburban has a push-button transfer case (NP243 as I recall), it's not a full-time case. Here's a pic of the suspension I built for mine, with Brandon standing next to it.
If you're doing the swap with leaf springs it isn't too hard to make your own brackets. When I have spare time I've doing a SAS on my 1997 K2500 Suburban, but I'm building a 4-link system for it. Since your's is a 2000 I'd check to see which transfer case you have, if it's a Autotrac (NP236 as I...
I'd check the fuel pressure first. Auto Zone rents the fuel pressure gauge for free, you give them a deposit and they refund it when you return the tool. Does it have a schrader valve to check the fuel pressure?
The LSx injector ratings are for the 60 PSI, not the usual 45 PSI. The LS1s had 28.8 lb/hr injectors in them, but if you run them at 45 PSI they are only 24~lb./hr. injectors. so if you run them at 49 you'll be reducing the output by quite a bit.
When we built the HHR for GM we had Clock Doc replace all of the electronics in the dash so that we could use individual sending units, in a worst case scenario you could do that.
Running two computers isn't the end of the world either, when I added after market ECMs to the late model Camaro's...
first thing I'd check would be the fuel pressure, then turn it off and see how long it holds fuel pressure. You dind't mention it, so I'm assuming that it isn't throwing any codes (turning on the check egine light).
If fuel pressure isn't the issue and no codes I'd look intot he cat after...
I've only done one LSx swap into a Jeep, but it was an older one. All of the gauges worked when I did that one. The tach I had to send out to clock-doc to get it modified to work with the signal from the LSx computer. For the oil gauge you simply drill and tap the little bypass plate above the...
