Ok, I for some reason just really want to get a Fast intake on my car. I don't know why because I can't justify the expense/hp, but I just want one. Maybe it's a badge of performance or somehting to have on the engine, engine bling maybe... LOL.

I purchased TSP 1 7/8" headers, TSP ORY and the Hawks 4" sinister exhaust. I would like to get this stuff and the intake on and have it all tuned at once and be done.

The question I have is, why would I ever pick the 92 over the 102? The 102 is cheaper($50), they both require a TB, but the 102 requires fuel rails($190). So I see a price difference of about $150 total. Not much when you're already spending that much money. Am I missing something???

 

I really don't know, but have to think that there is something more to it, otherwise I would agree that it's a better all around deal.

I'm interested in hearing some answers as well

 

You can get cheaper fuelrails than $190 for the 102, making it less costly over the 92.

It's got more potential, so why not at this point? Unless you just plan on a basic build.

 

If I had to do it over, I'd do a FAST 92. The 102 is fine, but the 92 would fit the car better. There might be a 5-7HP difference?

However, the cost difference isn't much. I got take of LS2 rails from SDPC (new but off of crate motors) for $95. I just bought Bosch injectors that were LS2 based with the EV1-EV6 adpaters that fit the rails and intake perfectly. I also picked up a take-off LS2 waterpump (new but off crate motors again) from SDPC for like $110. My stock pump needed some attention, so I was going to have to do that anyway. The LS2 pump clears the 102 without having to grind.

The 92 also allows for the stock MAP location. The 102 allows for it but the firewall doesn't. I had to relocate to the front, which is less accurate, but it works without smashing the MAP against the firewall. You can clearance the firewall, but I had the engine and trans back in before I realized that, so it was difficult to get in there and clearance it. I guess you could take a 2x4 or something and try to whack it.

 

Weird, I had to clearance my LS2 pump when I put on the 102.

Why is it less accurate there? And don't all LS2s and 3s come with it in the front on OEM manifolds?

 

I didn't realize there were so many clearance issues with the 102. So I take it the 102 was just built to fit the engine, the 92 was built to fit the F-body?

 

Pretty much, the102 was amde for the gto and corvette not the fbody. I got new ls3 take off rails for 50 bucks. With the 102 you need to make a decision about injectors before install. If you want to use ls1 style injectors you will need a spacer kit to make the rails a bit taller to accommodate the injectors. If you want to run ls3 injectors which are very short you need a spacer kit for the injectors themselves. The intake was made for ls2 units so those with the ls3 rails work without anything.

I ended up doing ls3 injectors as my stock ones were maxed with the ls6 intake and then bought the spacer kit. You will also need injector adapters should you choose to go for the new style injectors however this is true for either setup.

I did things a little different than jake. I like the map in the back so I simply drilled the map hole out like normal and put a threaded hose barb in then remote mounted the map, works perfect and i can even take it off if I need with touching the intake. The 92 will not require you to clearance the wp and push the steam tube down.

However, I've had 2 92's and now a 102. Never installed the others though, the 102 is a MUCH better built piece. The others have a flimsy base that's prone to cracking and 6 miles of rope gasket. The 102 has a sturdy base and individual runners.

I'll be honest that I mostly did the 102 because I prefer the looks over the 92. In the end the price difference is a wash because of what you may or may not need for your setup. If you plan ahead and know what to expect like I did the install wont take any more time than a 92. Its when you go in expecting it to just drop in like the others that you get screwed lol

 

The LS2 WP cleared no problem. But everything is a wash with that intake. And yes, it was built for the LS2 Vette and GTO, not the F-Body.

MAP is there in the LS2/3 but they have different sensors as well. Rear is more accurate because you could have varying pressure drops being so close to the throttle blade.

If the 102 is better built than the 92, then WTF. It's a GD POS in terms of build quality. Flimsy and crappy. It's literally the worst thing I put on my car in terms of build quality and the most overpriced thing I put on the car. And I put some overpriced crap on my car.

 

I have fast 36 lb injectors that were on the car when I bought it. How do I tell what style they are?

 

I've been wondering what's going on with all these 92's that have been showing up in the forums cracked or warped lately. That's one reason I've been considering the 102.

 

Ya dont ever go pickup a 90/92 then lol The top shells are about the same quality but the runners compared to the mid plate on the 92 is much beefier on the 102. Th ebottom floor on the 90's is 1/8" to 3/16" at BEST. It sreally flimsy and i could push it in and out with my hand. Theres 2 supports on the 92 that go from the midplate to the intake floor to help support it. My FAST 102 weighed 4 lbs more than the 92 my buddy had at the time. Thats a lot of plastic lol.
Best bet is to just get the part number and call FAST or post a pic here they can tell you exactly what you need.
And ya refer to my post above....I had a 92 and have seen plenty of them the 102 is built better no question

 

So the fast 92 is junk??? I hope this isn't true...

 

no lol the fast 90/92 are still great intakes but the 102 is bigger and better (literally) if you're buying new or close to new then the 102 is a better choice but if you get a smoking deal on a 90/92 i wouldnt be afraid

 

IMO, the FAST 92 isn't junk. After I read about 102/102 with clearance issues, needing new fuel rails, and needing injector spacer or injectors, along with possible tuning issues if you're not lucky enough to have a very good tuner within a reasonable distance from you. This is what made me decide to go with the 92/92 setup, and I'm still happy with it.
The only issue I found was that the MAP port hole in the 92 is slightly larger than needed so the seal doesn't fit very tight. I'd recommend putting rtv sealant around the seal before installing it into the MAP port, for a simple fix.
BTW, I also really like the color of 92 compared to the 102 which I think is ugly. Another option if you can't justify or afford the additional cost of a new larger TB at the same time is to buy a FAST or CBM(tapered better flow) TB adapter ($40-$100) and use the factory 78mm TB for the time being.

 

OK good lol. I got the 92 with fast tb for 1200$ shipped.
