I have to hand it to you! You took a junky piece of shit and turned it into a 11 sec sleeper

Only ONE thing you need to know. The MR2 is better in every, single, way.

If people would read their owners manual they would know.

LS2 with the same SAE Horsepower rating at the time of the LS3 would make 412HP The LS3 does flow much better out of the box with the intake manifold and head porting than an LS2 so once cammed or boosted it would make more of a difference. The 08-13 Corvettes got the TR6060 which is stronger and a beefier splined diff as well. The 09+ C6s all got Variable Steering and the LS9 block (also used in LSA) which made those engines have different bearings and more main bolts. This was to save on cost for only one production block (similar to LS1-LS6 did in 2001). The LS2 however does have higher compression out the gate. With a Cam, Heads, intake+manifold, and headers all that cost less than a LS3's parts it will make similar horsepower. The OE tune however pulls timing very severely to be safe. Even stock cars with a throttle body and tune see a increase in power on a dyno and the street.

@Toys4Life C5 you forgot about the Corvair!

A much better swap than the 3.8 is a VW/Audi 1.8 20v turbo and 6 speed box. Smaller, lighter, more tuneable and more reliable

No need for hi temp paint ?

That's the Fiero GM should have built. Buddy of mine had one in the 90s we used to rip donuts in place the front wheel would never leave its pivot point. Loads of fun.

I think a great Deal.....I had a 2009 Atomic Orange LT3 C6 that I paid 30K for in 2014.....it had long tube headers Billy Boat exhaust tinted top 6 speed manual..... It was one of about 400 of that year....53k on it when I traded it in on a 2016 C7 8 speed automatic...... I wish I still had the C6.....

It was always the engine. If the car had a better engine back in the day, Quad 4 or 3800 S/C, it would be on sale (and that abysmal 3rd gen Fiero would have been WAY different) at least until GM canned Pontiac... or maybe they wold not have.

You can just swap in a 3.9l 60 degree V6 to replace a 2.8 engine. Drops right in. Some came with like 240hp.

Bought a C5 hatchback a little while ago and I love this car and am no where near driving it as well as it can

That’s not a Nissan 3000gt. It’s a Mitsubishi 3000 gt. Nissan didn’t make them.

C&S Corvettes has a good video on the reliability differences between the two motors. Clean LS3 cars are hard to come by on the west coast. 200 mile range does nothing for your search results. You practically have to look as far as Texas. I had a 2005 LS2 car and after looking decided that getting into a C6 grandsport with the LS3 was a bad value so I ended up buying a 2014 Z51 Stingray. Interest rates are definitely a factor for the older cars!

Friend, amazon sells a water and blower wand that is skinny and fits in without having to remove parts. Works wonderful. Also, when you blow out your radiator, put a piece of cardboard between it and your condenser so your not blowing dirt from the radiator into the condenser. In any event, right idea.

Good info, but your "pop-ups" are only on for 2-3 seconds and difficult to read at that.

Great video

The C8 weighs 3600lbs, not 3300lbs. otherwise than that, this video is perfect! It's rare to find a video on youtube that is so accurate and insightful, you've got yourself a follower!

Beginning of the video: LS2 and LS3 are basically the same. End of the video: Ls3 has better motor components and better transmission. LOL

Toss a little 100 shot nitrous intonit

I’ve had both. I had 07 Z51 6spd manual and an 08 non-Z51 auto which means the weak 2.59 rear gear. The 07 had a Callaway Honker and Billy Boat bullet exhaust. I don’t know if it had a tune but I suspect it did. I bought it back in 09 at a dealership so couldn’t ask the previous owner. The 07 was a beast and much more fun to drive. The auto neutered the 08. Between the 2.59 gears and stock programming to upshift to OD even at low speeds it wasn’t really a fun car honestly. The paddles were slow. The only place it was fun was on the interstate from a roll if you went WOT and after it kicked down it was an absolute missile. I didn’t keep that car long. I compared it back then to flying a fighter vs a fast high speed bomber. Completely different experiences. I could absolutely tell the difference handling too btw Z51 vs non Z51 on the street.

No thanks

Put the Fast ( or better yet, the MSD ) intake on a LS3 & you are over 450hp, just though I would mention that

Looking at a 2008 3LT Z51 package Convertible , 23,000 miles, 1 owner. Low 30s. Thoughts anyone?

Outstanding Video! I had a C7 Grand Sport that I needed to sell since I was getting stationed in Guam for 3 years tour of duty. Navy here. Shipping it seemed like a horrible idea, storage was no good options for that long so I had no choice but to sell. Upon coming back this March 2024 I wanted to get back into a corvette right away. Since we just started a family and my wife is not working I opted for a 2013 C6 Grand Sport as a good compromise and I absolutely love it!!! At the price point it is a outstanding car. Still some modern tech and plenty fast for some parodical spirited driving and has wide body stance. Love the traditional circle tail lights that my C7 didn't have and most of all it is very affordable which is also important for ownership experience. Last thing I like a lot.... not active fuel management. Pure V8 uninterrupted goodness all the time.

Man that thing is a deceptive little sleeper putting down impressive times. I've seen some fast V8 swapped Fiero's but you can usually hear them coming from a mile away. My OCD does force me to point out a small mistake at 2:00 though. The Fiero was GM's first 'rear mid-engine' sports car. All Corvette were mid-engine(front mid) starting with the C1, as the engine has always been located completely behind the front wheels as opposed to above them.

I predicted the c6 was going to win. Having owned all 3 of the models discussed overall the c7 is by far the best. Coming in at a close 2nd would be the c6, especially since I had a 6 speed manual and I kinda miss cranking thru the gears. I had a manual c5 but the horsepower boost in the c6 made a big difference. So I do concur that if money is a significant factor get a c6 (manual). If you have extra cash get the c7. Imo the c7 looks alot better also. 😊

I do “daily” drive…mine…

Really like my LS2! Fast enough for my skill level! I have a relatively high mile 06 C6 with 115,000 miles on it, but has been perfectly maintained. Not hopped up and not beat. Only thing I wish was different is I wish it had a manual transmission!

Have the ls3 in the 5th gen camaro... that engine is an animal

03 without f-55 suspension. Is best

LS3 for me! No replacement for displacement.

C4's get an unfair reputation from optispark. It's definitely not the best place to put a distributor, but mine never gave me any trouble before or after preventative replacement. I had a '92 Corvette that ended up being the worst car I ever owned. Avoid the '92 - '93 model years. These early LT1 cars had the most frail powertrain control modules that create all kinds of buggy issues that are a nightmare to troubleshoot. Add mandatory t-tops, the awkward step-in over the beam that was trying to keep some chassis rigidity without a roof, bad power draw, and a frustrating position for a battery, and the car just wasn't much fun. A '91 with the updated body style and an L98 would be a sweet spot for a C4.

Can this kit manage the additional heat for road course lapping?

love your C6 content. Keep it rolling!

I think they are both good. I would get a 06 or newer just because the 05 had the four-speed transmission instead of the six speed and it had the older steering wheel from the C5 generation. But besides that the 06 to 13’s either one is just fine.

Say I have a LS2 and I love it . If I need more power it would be easy to beef it up . But I don't it's plenty fast to get me a ticket if I do not watch my speed. LOL

What is the latest fix for a P0153 code from lt headers

I've heard that the LS2 is underrated by GM because they didn't want the new LS2 in 2005 (400hp) to have more power than the outgoing C5 Z06 (405hp) on paper. I would love to see someone actually dyno a stock LS2 and LS3 on the same dyno.

I went with a ls3 cause I can’t keep anything stock. For someone who wants a stock, narrow body c6 than a ls2 is the best bang for the buck. But for someone who wants a wide body, dry sump, and has modifications in mind than a ls3 is a better platform.

Good video!

I always say zed because it’s fun also all I play is Led Zeppelin on my guitar

around WA state LS3 cars are like 27-35k but there also usually Grand sports so they have the wider body my car is a late 07 and i know the 08 cars werer the tr6060 but when i look at the gm options list/build sheet of my car it says manual tr6060 is it possible some late 07 cars got the tr 6 speed?

Also… as someone who’s done a couple of supercharged cars…. There’s an old formula that blower drive service , BDS, put out years ago, that I found to be fairly accurate in certain situations. Especially if you’re talking about 6 pounds of boost to maybe seven. As your boost goes up, your efficiency decreases, and then this formula doesn’t work as well to not very well at all. If you figure that 6 pounds of boost adds another .4, or 40% of another atmosphere to your car, breathing capability and you know that your car makes 1.14 hp/ cubic inch with an LS 3 , or 1.098 horsepower/ cube inch with an LS 2 one can guess the general ballpark for Peak, horsepower at 6 pounds a boost for an LS three (assuming supercharger efficiency is the same, and other factors are the same for both of them, which is an assumption for sure) of about 600 hp at the crank for the LS-3 and 559 hp at the crank for the LS-2. Try playing with that formula because it usually gets you in the ballpark. Again, remember higher boost figures start to play with efficiency, and then the formula doesn’t work so well. About the highest I’ve ever known it to Work was 7-8 pounds and even then it’s not as reliable. Six is usually real reliable.

I enjoy the videos. I own a 07 vette with a ls2 and a 14 SS sport sedan with a ls3 and they both had harmonic balancer issues.

Living in southern Canada, bringing it out after winter is a great feeling.

Id follow the recommendation on the computer. Plus I use extended protection high mileage Mobil 1 so even at 6-7k miles, the oil is good for double that. Synthetic oil is so good, that as long as you get it hot you get the water off, I wouldn’t worry much about it

Unless you are a professional race car driver you will not notice the difference. Most corvette drivers can’t drive their cars to 70 percent of what they can do. So the 7 percent difference is not noticeable. But morons waist money on silly mods that do little instead of taking driving classes. Iv seen guys in Mazda Miatas lap zo6s at VIR.

Thanks for always making great content. I’ve never owned a corvette but one day I’ll own one for sure, probably a C6, I’ve a driven C7 and a couple C8s but my heart still lust after the C6 generation.

I was told that the LS2 Was badly internal balanced...? But cant find anything on the internet about it. Has to be some horse shit rumor :) Thanks for the video :)😀
