How would I go about making this work..I have a 6.0 in my Camaro now & I'm going with the ls3 top end

 

Since you're not changing any sensors, should just be a re-tune...

 

You will need an extension for the map sensor harness because the LS3 intake has it up front.

 

how about the ls3 injectors?

 

You'll need a 4 bolt TB. Are you running DBW?

 

No I'm going to get a 90mm tb

 

Everything is pretty strait forward. Like stated above, all you have to do is extend the MAP harness, and find a way to keep your gen 3 map to stay in place. Also you might have to re pin the computer/harness depending if the computer is wired for DBW. Other than that, there is an excel spreadsheet that is floating around here, and the hptuners forum that has the correct injector data if your using stock LS3 injectors. I am running a 408 LQ4 with the LS3 top end, and it runs great.

 

How about the crank sensor convertor. PCM is 24 the engine is most likely a 48.

 

If it's an LQ4 or LQ9, its a 24x reluctor wheel. If it's an LY6, it has a 58x.

 

You will only need map sensor extension and if running ls3 injectors some plug n play harnesses. Both can be bought by most sponsors. I got my stuff through TSP

 

Then you would need this. You can use just the crank, cam, or both, depending on your needs.

Bingo. I'd definitely check first.

 

All you need electrically to make it work is the 24 tooth crank and 1x cam. You could even upgrade to a newer single bolt cam but you would need the conversion front sprocket and the relocated sensor, since the single bolt cams no longer read from the rear like traditional LS1s.

 

I already ordered the injector plugs & the extension harness..think that's it..& a cable driven 90mm tb which I'm about to order
