Depends on what the HP/$ gain will be to you.

Personally, I would, if you can get a decent amount for your combo and only come out of pocket a little bit for a 92/92.

You will see minumum gains for the extra bucks spent on the swap. Not worth it in my opinion.

You should at least port your 90mm if it isnt already.

I thought the only difference between the 90 and 92 was the slightly bigger opening (by 2 mm) and the fact the internals are openable the same as the 102. If that's the case, then you prolly won't see any performance gain at all, 2mm bigger opening is meaningless...and nothing that you can't open up yourself on the 90.

This is what I thought as well. The Fast90 and 92 intakes are exactly the same except for a 90mm and 92mm TB openings. There would be no gain what-so-ever if this is true because a 2mm TB opening won't make the slightest bit of difference in this case. OP if your Fast90 isn't ported, getting it and the TB ported by a reputable shop would do much more justice rather than swapping it for a Fast92.

Don't waste your time, as been said, nothing to gain between a FAST 90 and a FAST 92 except a thinner wallet. If you want some more power, have your FAST 90 ported, it should be good for about 10 hp or so.

Yea, Its the same intake with the exception of the throttle body opening.

The increase in power would not be worth the cost of a 92 or 102....that is unless you are looking for every last pony.

It's the FAST 102 that is a slightly different design.
