Can I swap my siemen's 60lb injectors and fuel rail from my ls2 intake over to my ls3 intake? Both are GM. Thanks

Your rail will need a 1/2" spacer. There may also be the issue of EV1 vs EV6 connectors. Both are easily fixed. Katech makes a kit.

Ok, I am swapping intakes so the ls3 intake will be on my ls2, therefore, the connections are not a problem. Thanks

What heads are you using? Hopefully you are aware that the LS2 was cathedral port and LS3 is rectangle. :-)

Never thought to ask. Will the ls2 TB bolt right up to the ls3 intake?
