Best intake I have a 02 trans am ls1 with a cam 232/239 .595/.605 111lsa ,ls6 intake , stock 241 heads, and basic boltons well I made 375 rwp! I'm planning on getting a fast intake but I don't know whether to get a 92 or a 102!!! Can somebody tell me the ups and downs on both of them? What all would I have to change to put either on on like fuel rails or grind stuff like most say with the 102
Fast 92 - all of your existing fuel rails/injectors bolt right up.
Fast 102 - needs ls2 style fuel rails or aftermarket. Spacers for the injectors if you're keeping ls1 style injectors. Alil grinding on the water pump (no big deal imo).
Both will need tuning to be efficient and run 100%. May have to modify your existing bellow to fit perfectly.
I went with the 102 because I'm running a lq4 and plan on a 408 eventually.

already having an 2002 car with a LS6 intake... I would just leave it to be honest. Unless you do some major cylinder head mods... not worth spending $1k on an intake! I made 15 more whp on shitty 91 cali hippy gas... i'm just running LS2 243s, 02-04 Z06 cam, full bolt ons and a 78mm fast intake manifold which is basically equal to a LS6 manifold. The fast intake really only make more hp in the upper 6k+ rpms with big cam but most importantly, heads to support it... I only bought my 78n fast intake b/c it was $400 shipped and I still have a LS1 intake man with my LS6 top end and still only netted about 8whp after 4500rpms
Get the ported heads 1000x before the FAST. Should always be the last mod IMO. I did it and it was good for 14rwhp from 4500-6500..good but heads will get you way better results fpr the price.
