Re: My 1989 IROC LS1/4L60E swap

I did get some other goodies.
My new 120A alternator. It solved my pulsing lamp issue and I swear the car runs better


Also found a guy in Washington that had these rocker emblems. I bought red ones as well. We will see which color works best with the paint.


And lastly got my Koni Yellows in. The rears are installed, Just waiting to get the fronts installed and swap front springs again.



Also snagged this BRAND NEW dash Face!



Other than that, Still saving for paint.

Oh well, Pics of progress.









I am thinking about ls swapping my 89 IROC and was wondering how much that a/c bracket and power steering bracket was and how you found it on summit. Thanks.

The AC bracket and adaptor were all I bought. The PS and everything else is all stock 98 Camaro LS1.
Just search the part numbers in the pic on summits web site and read the instructions. It will lead you to the correct adaptor bracket for whatever water pump and stuff you are using. The bracket, Adaptor, Two extra pullys and belt ran right at $300.00

Re: My 1989 IROC LS1/4L60E swap

Howdy Fellas, I havnt been here in a while and had a question.
As far as the factory tachometer in the 89 Iroc, What are the diferent methods to getting it to work with the LS? I sent mine off to a guy in Louisiana to have it fixed and when I got it back I found that it only reads 50% of the signal. Come to find out, The LS V8 signal is the same as a 4 Cylinder. So that makes sense. Question is, Are there any other solutions to getting the factory tach to work?
I have looked at the DIP Switch box that is sold by Abbotts.

http://www.atrol.com/order.htm

This little box (an ERA) costs $180.00. Are there any other alternatives? Thanks as allways.

This same thing happened to me while I was changing out a transmission filter. Barely twisted it on there and SNAP. As I was drilling it out, I also got a metal shard in my eye and had to go get it carved out. Needless to say it wasn't fun. Sad part, is I was wearing safety glasses. I think it was stuck to my shirt or something....

Re: My 1989 IROC LS1/4L60E swap

Metal in your eye is never good, I hope you healed ok.
No real updates on the Rock. haven't had much time to tinker. Have been taking it to a few body shops but they are nuts! 10K + to paint the car 3 stage Ruby Red. In my frustrations in trying to find a good but reasonable body shop I think I may hold off on finishing it for a few years. Some things are just not working out and we may need to find a new House. Which means The money that I had saved for paint may need to go towards a down payment on a house. Not the way I wanted this to go down but if I do that I will have a garage so That's a perk!
We'll see what the future holds and someday RubyRock will be complete.

Re: My 1989 IROC LS1/4L60E swap

Well, It's been a while again. Finally got moved into new house and getting settled in. Hoping to get going on the project again soon. While I am still looking for A painter, I am also debating Wheels and tires as well as a Power adder. I have everything to install Nitrus on it I am thinking of not going that route. Looking into a Whipple or Magna charger.
Has anyone here known of a build with either of these set ups? Would love to see clearances. Any help would be appreciated. Thanks.
