FAST 92 vs FAST 102
I'm making a lot of changes with my 04 GTO this winter and the only one I'm struggling with is the intake manifold. The csr used to have a small cam with ported 243 setup, a fast 92 and an M6, but now its going to a 238/240 with a TH400 and a 5400 stall. Street driving isnt a concern but with the extra airflow of the new cam on stock cubes, is the jumo to the 102 going to get me anything extra on the top end?

I wonder if these manifolds have a different effect based on the size of the motor you are using.
For instance, in a 5.3L, is the manifold swap increase greater or smaller than on a 5,7L or a 6.2L?

Fast 102
The 92 is nice but the 102 is better
The same reasoning behind going 1 7/8 headers over 1 3/4
Some guys go chromoly vs mild steel suspension/cages for the weight saving at double the cost..
The name of the game is more hp, that being said if you can't afford it you can't afford it..

Thanks for all the replies guys. I'll look into getting the intake ported vs the cost of a 102. As for the chromoly vs mild steel on my roll bar, Im going with chromoly because the GTO is already a ridiculously heavy car

Its really hard to say without proven track numbers if it would actually make the car faster. Dyno numbers dont count in my book unless its back to back.
That said i switched from a 92/92 ported setup to a nw102/self ported fast 102. What i like about the 102 is that you can accurately port match the runners to the head inlets without guessing with a measuring tool because it comes apart internally. I dont have any track times or dyno numbers to compare.
The swap cost me a total of $385 from ported fast92/ported stock tb to a nw102 and self ported 102. Not bad if you do the work yourself and buy good used parts.
In my opinion, sending these plastic manifolds out for a port job is not worth the time, money and effort. You can do it yourself with some experience, research and the right tools.
