FAST LSXR 102 Intake Upgrade for the LS2 Powered C6 Corvette (It was TIME!)

[@ordovicicosilurico6799]

man i really enjoy every video you share with us !! great information and excellent explanation ! thanks and ill be waiting for the part 2 👍🏽👍🏽

[@Toys4Life]

Thanks for the kind words!

[@noahloyd9]

I did it! after a year of saving And dreaming , sitting in my car now. She ain’t perfect, but she’s mine ❤ thank Jesus. Been watching for years

[@Toys4Life]

That's awesome, enjoy!!

[@WarriorsPhoto]

I am very excited to see the results. Corvettes are a fun hobby. I appreciated you saying we all work with what we have. This is true and this hobby can get expensive for the unaniciated. 😊

[@LS1LT1]

It really does make a huge difference. I had the FAST 92mm intake manifold on my C6 LS2. Along with the other bolt ons (headers, higher stall torque converter, ported stock throttle body, Vararam Snake Charmer, ATI underdrive pulley, dyno-tuning, drag radials and skinnies etc.) it'd helped me run a best of 10.7@127+mph in the 1/4 mile. Stock internals/naturally aspirated/bolt-on mods only, in good air of course. Don't throw out that old stock LS2 intake manifold though, it is still worth a little money. 🙂

It is nice to have room for more horses in your barn. Sweet!

[@InTheHookJohn]

I added a fast 102 to my ls2 and love it!

[@FEAR_Actual]

My buddy has a 2006 GTO with the LS2 and a T56, and he recently did a FAST LSXR 102 to it as well as a Texas Speed chop monster cam. He already straight-piped it, and threw headers on and it's been retuned. As is, it's an absolute rocketship now for being NA stock displacement. I can feel the difference riding shotgun, and it sounds amazing. I'm thinking of doing an LSXR to my C5 z06 soon to help with airflow when running a boost cam that I have to swap in for my A&A kit.

[@American_Jeeper]

I watched this last night and am watching it again....I'm glad I did, because I just realized that you didn't replace the throttle body. So you can keep the stock 92mm throttle body and it will bolt right up to the FAST 102? Does FAST explain why only that one corner of the intake needs RTV?

[@ctvette1318]

Can’t wait to see part 2!!

[@mlapointe88]

I really enjoys your videos, thank you for all of the hard work you are doing in order to provide us with the proper information. I do have a question, I’m having a hard time finding the manifold O rings that specifically say for LS2 engines. Which ones from fast did you get? Thank you 🙏

[@justinlanglais9825]

That's a great upgrade.... how about a nice set of American Racing or Kooks long tube headers next? That'll give you another 20 HP and torque bump !!! 👍🏼

[@Toys4Life]

I would love a set of kooks, but I think they're close to two grand with the X-Pipe.

[@justinlanglais9825]

@@Toys4Life awwww... go for it !!!

[@BannonTube]

@@Toys4Life You’re only off by a little bit. 😅 I had Kooks long tube headers and the X-pipe with the green Catalytic Converters installed on my 2012 Grand Sport (M6) in April. Parts alone were $3417.00. I’m told the old Kooks HF cat equipped Xpipe is no longer made but even that combo was $2400. I love the difference my setup along with a Haltech intake and a tune has made. No change drivability, but it runs like scalded dog when you put your foot in it. I love the format and content of your channel. It’s helped me make informed decisions regarding the plan I take for my Vette. Maybe this is addressed in part two but any thoughts about the benefits or lack there of the FAST LSXr 102 manifold on the LS3? Keep up the great work! Thanks, John

[@swappedoutZ71]

Ls6 manifold would have done you justice for cheap, but the fast is much better

[@Toys4Life]

LS6 manifold wouldn't fit my larger throttle body.

[@shawnjackson5623]

I had no idea the LS2’s intake manifold was so inefficient. It’s cool to see that these cars are still being modded. How difficult was it to learn how to tune? I remember way back it was a big deal and cost more than tuning a Ford. Looking forward to PT2. Thanks for posting.

[@leonlawrencez28]

I actually bought one of these LXR intakes for my 01 C5 but I returned it. I wasn't sure if I could use my stock parts with this LXR. I was thinking it was a direct bolt in. I wasn't sure with all the research I did so I just returned it. I already had a BBK throttle body and it looked like it wouldn't fit properly. The research I did find out was the factory intake on a 01 C5 was pretty decent to begin with so I just kept it as is with my throttle body and long tube headers/ x pipe. Maybe in the future by watching this video part 1 and 2 I will reconsider buying and installing one.

[@nowayjose596]

01-04 C5s came with the LS6 intake which was a definite improvement over the LS1 (+10-20 rwhp). It's kind of weird that GM then took a step backwards with the LS2 intake (followed by another big step forward with the LS3 intake), but I'm sure they had their reasons. The LSXR 102 on a C5 also requires aftermarket fuel rails and some clearancing to clear the cowl I believe. In your case, since you already have an LS6 intake, definitely not worth it IMO bc you wouldn't see nearly as much gain compared to those with an LS1 or LS2 intake.

The fuel line does not have to be separated. After you have removed the fuel rails and injectors, the fuel line will rotate up and back and it will rest on the windshield and be out of the way. Be sure to put a large cloth on the windshield to protect it. This has been done many times with no ill effects. Regards,

[@Toys4Life]

100% agree. I like to do it anyway so that the inevitable gunk that ends up at the tip of the injectors can be cleaned plus I like to clean the rail with it off. But your point is accurate and appreciated!

[@GregorioLonewolf]

Great Video. I've liked FAST for many years now. Question- why not go with a larger (102mm) Throttle Body? Anyway, looking forward for part 2.

[@christophershafer5615]

I would be interested to know how the pedal response feels if you switch to a cable throttle for the 102 vs the DBW.

[@Toys4Life]

I'm not sure that's possible utilizing the factory PCM in a LS2 Corvette. If somebody knows otherwise, please let me know!!! 🙏

[@racingdreamz8021]

I’m gonna also swap to the fast intake but I will also swap the heads to LS3 style rec ports, The LS2 heads are very limited & don’t flow well

[@Toys4Life]

IMO LS2 heads flow well - but the LS3 heads do flow better (:-). LS3 intake is decent - doesn't benefit as much from the FAST LSXR 102 from the majority of feedback I have seen. If a guy could find both heads and the intake for a good price it would be an even better mod!

[@tonym6854]

Cathedral ports is where the Lsxr shines

[@darrylsjodin7184]

If you know the oil pressure sensor is the original, it might be worth replacing it while you have the manifold off.

[@Toys4Life]

Good point but IMO - With these LS Oil Press Sending Units - Even new ones fail quickly sometimes. Some last a LOOONG time. I should probably do the relocation kit....

Is this Tony Mamo? Speaking of boost, I believe the LSX102 has been strengthened to be able to handle more boost (if so) how much do you you believe it can handle?

[@tonym6854]

No. Just same first name. I have no idea how much boost it's rated for but I'm sure there's videos on this.

[@Toys4Life]

I believe the older design has been known to pop but the newer LSX r102 can handle significantly more but who knows..

[@foxbatmotorsports]

How well would this mod perform on a stock '03 LS1? Would I need to increase my injector size and add headers to see any gains? Would the increased volume slow the airflow and kill off low end power without adding the other mods?

[@Toys4Life]

There is no 93 LS1 that I'm aware of.

[@foxbatmotorsports]

@@Toys4Life apologies, I meant '03. C5 Corvette.

[@Toys4Life]

The 2003 C5 has the LS6 intake manifold which is decent. I would not upgrade it due to the cost benefit ratio being poor.

@@Toys4Life Thanks, I'll wait until I do the cam swap and headers to do the intake manifold and I'm still learning my way around the HP Tuner.

[@wildazme]

I have a question for anyone who may be able to help. I have a 2005 base corvette with automatic transmission, from what I understand it'd an early production vehicle. I wanted to use a predator hand held tuner on it, which I know isn't the best, but I wanted to adjust fan temp and firm up my shifts some, and whatever little performance boost I could get on a pretty much stock car except for an intake and catback exhaust. I can't upload the tuner onto the car because of the programming on the car and it being an early production car. I've been told it needs the firmware updated, but the dealership wants a thousand dollars for this which is crazy. Can anyone help me out with this? Thanks in advance.

[@Toys4Life]

Hmmm, interesting. Did Diablo Sport Customer service confirm this is a known issue for their scanner with early model C6's?

[@wildazme2006]

Yes I have confirmed it with them, they said it needed the latest software update from chevy on the vehicle.

[@ViperMods_216]

You have to port these, the build quality is suspect on the lsxr and the msd atomic

[@Toys4Life]

I don't agree that they have to be ported. Will Tony mamo add another five horsepower or so by porting, probably. That having been said, and part two coming soon, I inspected the ports and everything in general and it appears to be decent quality to me. Perhaps they had some bad batches made on Friday afternoons?? Who knows.
