I'm in the middle of my winter upgrades and I have started kicking around the idea of going from my LS6 and ported tb to a fast 90 or 92 setup. For the same price as a 92 I have found the 102 but this is an afterthought and I don't want to take money away from what I'm doing to get fuel rails for the 102. If I can get about 500 out of my current intake and tb I will pursue this a little harder.

So enough bs. Does anyone have input for me or have a link that will help me decide?

Stock bottom end
224r Texas speed cam
Ported and milled 241s (with thinner gaskets should be ~11:1)
LS6 manifold
Ported stck tb

No emissions
Wet nitrous (either 100 shot or 150. Tested system last season but shitty track wouldn't let me really put it to use, so I'm not sure yet what I'll be spraying)

 

Fast 92 would work just fine IMO. Or just hold on to your money make some passes on the bottle and see if you could utilize that money else where if you needed. Ls6 is a pretty Good manifold.
