Fast 102 will not fit on stock 243 LS2 heads. The intake ports are different. The FAST 92 will fit 243 heads. Fast 102 is made for LS3. I run a FAST 92 haven't strapped it down to a DYNO yet but as soon as I due I will post before and after tune numbers for you.

The new FAST 102 will fit the 243 Heads without all those mods we had to do. We just don't have enough numbers yet to conclude its better than the 90/92. Fast 92's with stock 243 Heads are getting to 400 RWHP and
slightly beyond beyond. I managed to get to 408 RWHP/ 412 RWTQ
I would suggest getting to the DYNO and get some base numbers. Also
A Pro Tune will be necessary to see 400RWHP +
As far as track times LS1Lt1 and Dennis NJ have gone into the 10's. But thats not the average. 11.40 with a good set of tires and a reasonable 60'.

They make a few different versions. They make a FAST 102 that will fit the 243 heads. This is the one I am interested in.

I started a thread about a month back and I was told that the FAST 102 would not work with 243 heads. So I purchased a FAST 92. Is this an new 102 that just came out? Sorry for the misinformation

No problem! Here are a few different FAST applications from one of the forum vendors.
just installed mine on my ls2... not much done to it, just a vararam, ported throttlebody and then the fast, with a tune it was 377whp and 370wtq....now time for headers
I just finished my install around 2 weeks ago, LG headers with cats, Z06 catback, Callaway Honker, FAST 102 with ported throttle body and I dynoed 399hp/392tq.
Man I wish I would of had this info about a week ago when I bought the 92. Thanks and again sorry for my mistake. What kind of power difference is going from a Spin-Ported 92 to a 102? You got my interest now.

If you are referring to me (sorry if not) I have a Spin ported LS2 intake not a Spin ported Fast 92 intake.
I am not expecting much (maybe 5-10?) from this swap with my current setup but feel when I do a cam swap down the road is when I will see the real benefit.
Again, sorry if your question was not pointed towards me.

I am currently running a spin ported FAST92. I wanted the 102 but from my thread I was mislead into thinking that the 102 would not fit. My set up as of now is
FAST92 Ported by Spin
Ported LS2 TB
Ported and Polished 243 heads
Cam
Push rods
Roller Rockers
313lb. springs
titanium retainers
Snack Charmer 2
kooks 1 7/8 headers
X pipe [off road]
2 QPC cut outs
Dyno Tuned before CAI,TB,Intake
I run a good sized cam and the heads flow 283 CFM on the intake side and 180 or 190 on the exhaust. Don't have flow sheets in front of me. It made 477 RWHP and somewhere around 450-460RWTQ. Again I don't have the sheets till I get home. That's why I wanted the 102 lol
NO...no modding it at all. It just bolts right on. Probably takes no more than 30 minutes to remove the old intake and swap out the injectors and fuel line and bolt the new one on.
