How do I go about running a 90mm ls2 dbw tb on my 2004 lm7 with stock dbw intake and stock dbw tb. Do I need an adapter?? What are some other stock tb's I can use? Do I need to just stick with the stock tb to not loose low end?

 

You would need a adapter plate and an x link but if ur gonna do all that might as well do a tbss intake manifold swap

 

Are you keeping the stock 3bolt intake, or upgrading to the TBSS/NNBS 4 blot intake? If your keeping the stock 3 bolt it wont be worth upgrading the TB to a 90mm LS2. The stock intake only has around an 80mm opening. Pick up a used TBSS/NNBS intake, swap it on, and have fun.

 

I agree with these guys. Go with a used tbss or it's not worth it. You will need an adaptor harness either way. torquerushperformance.com
