I don't really know what you mean by "recommended" you money would be better spent of a cam, so in that aspect I don't recommend it, but if you are just asking are far as if it will damage the motor, it will be fine. You will see a power increase, but not much till you get a cam and heads.

Well I want to make my car a "full" bolt on car before I do any type of cam or heads....I wanna see what the best power a full bolt on LS1 car can put down. For now I have the LS6 intake and stock TB.....

Launching!
is what people are saying is, yes you will gain power with a 90/90 setup but you dont have the other parts to get full advantage/gains out of it. if you havent done a cam or heads yet you can get better gains by doing them first.

About 6-12 months back I did a ported 90 FAST for one of the members on this board who is very competitive racing in the SI class.
He picked up 12 RWHP peak but 20 RWHP past peak and was very happy about it for obvious reasons.
A 90 mm FAST is not "too much" for a stock engine....The manifold /TB combo represents an air valve (not a carb) and a less restrictive air valve lets the engine make more power. Everyone confuses this with the old school thinking of overcarbing an engine. That was a legitamate concern because too large a carb would provide poor airspeed, a crappy signal, and not atomize fuel very well (a bad combination).
You could run a 2000 CFM TB on a bone stock engine and it might not make more power than a 1000 CFM piece, but it wont hurt the power curve at all.
I'll be damned if I cant remember his name (the guy I helped)....Im fairly certain it was David and he lived in North Carolina. If I remember I will repost.
Thanks,
Tony
