What is the recommended FAST setup for a cammed LS2 (90,102,ported,etc)?

timd38

You can not buy a new 90 any more, so a 102 ported would be my recommendation!

I think the only major adavantage the 102 has over the 90 or 92 is the fact you don't need to cut the firewall.

A. both poster's are correct B. porting is a sure fire way to pic up to pick up HP. If you're mechanically inclined & understand the simple dynamics of airflow & consider your time free, do it yourself & save the $$$, & don't leave any HP on the table. It's a valuable add to any C6, but particularly w/ a cammed motor.

So is the 102 a simple R&R or are there more parts required (fuel rail stuff,etc)?

timd38

Nothing is ever as simple as the instructions say,

The 102 is a direct swap and u wont need new fuel rails or anything. And id have it professionally ported.

Where's good place to get a well-ported 102? I think I'd probably ruin it if I did it myself.

Also, where can I find install instructions? I want to see if it's something I have the tools / skillset to do myself.

What kind of RWHP/TQ Do you/Could you pick up with this mod?

Fissile

From what I've read, a ported FAST 102 with a tune is about a 30-35 rwhp increase over a stock LS2 intake manifold.

Seems unbelievable to me, but some people have posted their numbers on here.

If your car is already modded and already tuned you'll pick up generally somewhere in the low 20's rwhp at peak and probably closer to 30 in the mid-range with either the ported 90 or ported 102.

Lethal Performance was having a good deal on the 102s.

U can buy from them but id send it elsewhere for porting. IMHO ...

FloydSummerOf68

Why is that?

I just saw that they had a good price on the unit

Bill Curlee

One of the BEST Intake Porters on the planet for the FAST manifolds is Tony Mamo. He just doesnt PORT, it's a work of ART!

If you need FAST porting, contact him!

Here's some great instructions. It's a great mod.

so it's difficult to say. I believe a well done port & smooth as glass FAST may pic up 10-12+ hp/tq & there are comparisons out there to verify. What I can say I went from a 377/372 rwhp/tq (LTs & VR cai, no tune) to 452rwhp/418rwtq, so I picked up 78hp/46tq. My cam is considered mild, 228/232, .598/.601, 114LSA. That said, a 50hp gain from that cam would be pretty solid if not quite high. So do the math, bare min. 25-30 peak, but what's really nice is 400 rwtq at just north of 3500 past 5500, peak at 4500, which is what get you movin' 'til hp takes over at 5250 where the hp/tq curves cross. If you look at the avg. LS2 stock w/ 6MN, there in the low 340s/330s for rwhp/rwtq, so in total I picked close to 110rwhp/90rwtq, with exceptional driveability. I understand the 102 is worth a few more, 5-7hp, over the 90-92s.

To other posters re: porting, I have know doubt there are people who can do magic w/ porting, but the fact is, the FAST intake is simple to port, & if you want to DIY, a file & sandpaper is all that's necessary. Not to say that's all I used, as it would be quite time consuming. But once, I took off the heavy areas (& that's very relative), I sat w/ several diff. grit sandpaper while watching a football game half working/half watching & by games end, every transition, edge, or imperfecton from stamping was smooth as glass.

Bill Curlee

I ported my FAST 90 in my basement and I had a BIG pile of plastic dust when I was done.

Theres quite a bit of material to remove and if you go all out, you will use a significant amount of filler material (epoxy) to add to several areas to be able to properly shape them to their fullest opening diameter.

If all you want to do is smooth out the bumps and match the port, yea, I guess you could do it in your living room.

Mike V.

I put a lot of time effort, & planning. I started outside w/ an air compressor & air tool, as I stated to get the "heavy lifting" done, but once I got all the material off & pretty smooth, I'm very meticulous & wanted it smooth as glass. So just sanded away 'til I got exactly what I wanted. Football games are over 3 hours, so no mistake, I had a lot of time in it.

The same goes for cutting to clear firewall using 18G sheet metal & JB Weld (slow drying) which took forever & had to constantly move position to avoid running. Once dry it was a pia to sand. Made an insert wear drilled for the MAP sensor to provide a tight surface the lenght of the entire tab sealed insert w/ JB Weld also.

The finished product will never leak, & looks like it came from FAST that way. But the proofs in the pudding. How many LS2s w/ a 228/232 cam & zero headwork make 452rwhp/418rwtq w/ the reg// bolt-ons.

Mike I know when you did yours (FAST 90 ) and it worked out very well
with your numbers but I would not recommend it for the average guy.
I did mine right around the same time we were discussing the Firewall
patch. I did my mods but left the porting to the PRO's. There are a couple of them out there Spinmonster, J Formatto and Tony Mamo if
he is doing them. The 102 solves all that butchering especially for us
LS2 Guys. There is about 8 -14 RW from porting the FAST 102 and for someone who gets a 102, gets it ported and a tune can see 35 RW and
with a set of long tunes with that package can see 400 rwhp in a bolton LS2 and 450+ with a proven Cam. Leon
