Great video! Can’t believe it’s taken almost 30 years for a genuine comparison video between the LT4 and LT5, with nice production quality to boot!

Thanks so much! When researching this video, I couldn't believe no one has ever pitted these two cars together, especially as the LT4 was essentially a replacement for the LT5. After running this test, my personal conclusion as someone who likes to daily their Vette is to save up and go for a late-model ZR-1, which I think is the best of both worlds! Its an intoxicating sound for sure.

@RetroCarsForever have you thought about getting a guy who tracks cars to test the ZR-1 with modern performance tires like Pilot sport 4S? Back in the 90s the original tires were basically all seasons. I'd love to see lateral g tests. Plus the look on your face when holding on mid corner would be fun to see 😅
@RetroCarsForever9 ай бұрын
Well, both of these cars have pretty aggressive modern rubber. No All Seasons here (though my C4 originally had All Seasons, you can see in some of the older shots from older car shows, I replaced them with Continental Extreme Contact Sport summer performance tires just in time for the actual comparison test). Big difference in grip for sure!

I have a base '93 C4 with the LT1. It came with a chip to delete the 1-4 shift and gives it a bump in HP. Also just recently picked up a '91 ZR1 that needs, at the least, a clutch. I thought it needed an entire transmission but turns out it actually did move in gear but slipped like crazy. Hoping to get it on the lift soon and check everything out. The base '93 has 150k miles and looks like it. But still drives great. The ZR1 somehow has 110k miles and looks like it has 10k. Nothing is worn out. Only thing interior-wise that doesn't work are the air bladders in the seats. Can't wait to get it driving!

I purchased a base 1993 Corvette a few months ago. I noticed the car sitting for a year or so and finally decided to stop and check it out. Turns out it had a for sale sign behind the windshield that had fallen. The interior looked decent overall but, the body was in rough shape from sitting, but decided to call the number on the sale sign. The owner told me it ran but the transmission was bad, probably 4l60 issues or tv cable adjustment. I bought it, towed it home and made a few posts/calls. My friend buys and sales cars on the side and had a spare 4l60e from a pickup laying around. I made the necessary mods to get it in the car and to my surprise it worked. I installed a micro controller from eBay since the car has no provisions for electronic transmission control and didn't want to drop the coin for a transmission controller not knowing the state of the transmission at the time. I installed the trans go vac-46 mod to control the transmission pressure since the max line pressure was causing very firm shifts. Before I purchased the car I watched a few videos from this channel that pushed me towards the car. I wanted a c6 grand sport, but ya know, life. Overall pleased with the cars performance even though it has a ton of maintenance to be done.

I picked up a Polo Green LT4 with 53K miles for a song a couple years ago. It needed some very minor mechanical work, which I was able to do myself (replace fuel sending unit, new pads/rotors all around), and still needs some radio and carpet repair which I'll get to in time, but I am thoroughly enjoying it. My young son's baseball teammates get a kick when we pull up for gameday! LOL

Thats awesome! I actually wanted a Polo Green LT4 but couldn't find a nice enough example when I was looking (so went with this Collector Edition instead). It's a great color. I'm sure kids love seeing the pop up headlights in action too, considering that's something they dont see anymore either!

I’m lucky enough to own a 91 ZR-1 and a 96 LT4 base convertible . Both are great are great cars to drive . The Z has some mods , exhaust, chip , lowered , wheels & tires 4:10s. It’s fun to drive but can be an assault on the senses. The LT4 convertible is a joy to drive in the summer. For all out performance the Z is the clear winner, but for an all around driving cruising car the LT4 is tough to beat. Both are great cars in their own way.

@@RetroCarsForeverThe LT4 was underrated. I used to run around with the F-Body and Corvette guys having owned both. Every LT4 I saw dyno'd was putting out only a couple of HP over or under 97 LS1s at the time. Not only were the C5 guys upset about this, but they were even more upset they were pretty much in the noise with the 98 F-Body guys as well, that their Corvette LS1s didn't put out more than their F-Body counterparts. I understand the LT4 was a 350hp engine in reality but the 97 LS1 was only 345hp, so GM underrated it to not overshadow the newer engine in the next generation. The LT4 was a different beast from the LT1. I had a 97 T/A with an M6 and it felt like it ran out of breath at the top end. My LT4 I hit the rev limiter on occasion if I wasn't paying close attention because it felt like it wanted to keep pulling hard. IIRC, some folks pushed the rev limit to 6500 on these with programming and it still didn't run out of breath. From what I remember, the LT4 was built with factory race catalog parts, everywhere it mattered from the crank to the timing chain to be strong, to bridge the gap between the 95 ZR1 leaving and the 97 new model and engine that was coming. It was feared that GM couldn't sell any Corvettes in 96 if they didn't offer something unique in the ZR1's absence. I also read the ZR1 was dropped for 96 due to GM not wanting to make the investment in getting the LT5 ODBII certified, and that if the LT5 had continued, GM and Lotus planned to push the car to 500hp eventually. I still have my LT4, owned since 2002 but I'll have to get rid of it before much longer and go with something in an automatic as a weekend toy. I love the car but my knee can't take the truck-like effort of the clutch in these older vehicles anymore. I don't drive it anymore because of that. I also can't bring myself to get an automatic either as it just doesn't feel right. My first Corvette was a 96 LT1/A4 and while it was a Corvette, I just didn't feel right in it being an automatic. I'm thinking an 09 XLR or 13 Mercedes SL550 as a retirement toy, something that's a hard top convertible as I miss having one of those too. I'm old now, in my fifties, so I guess it's just the natural progression of things. On the negative side, the later C4s seemed to suffer from GM's cutbacks. Both my 96s felt like junk when you took the targa top off, heard the term "flexy flier"? The 80s C4s I drove felt pretty solid to me with the targa removed. I also believe when you mentioned the ZR1 felt better on the canyon roads, that it was due to extra bracing the ZR1 cars got that the base Corvettes didn't get. I don't believe the ZR1 had any complaints with the top off. One thing I worry about in keeping one of these around so long is that I understand you can't get the dual-mass flywheel anymore and that it's a different experience, and a noisy one when you switch to a single mass flywheel. I believe all the LT1/LT4/LT5 cars have the dual mass flywheel.
@RetroCarsForever9 ай бұрын
@@Shadow_Banned_Conservative Agreed with all your thoughts! I am surprised about the chassis stiffness comparison, as haven't driven an early C4 with targa off back to back to compare. Also wasn't aware of any significant chassis bracing with the ZR-1, didn't remove the top to see on that one either. I do know my 1996 has noticeably more flex with the targa removed!

@@RetroCarsForever UGH, this thing ate my long response, don't have the energy this late to retype it out. Abbreviated version. I can't find the reference now to the ZR1 chassis differences. I came across a picture of the C4 frame a long time ago that I remember having the ZR1 differences highlighted by using a different color. I'll see if I can dig it up maybe on the long holiday week. I had quite a few Corvette books back in the day, so I might still have the reference I mentioned. Also, huge difference in chassis stiffness between my 96 and my friend's 87, I drove both back to back with the tops off. I still have it in the garage, but there used to be a company called "R&D Racing" back in the 1990s. They built and sold a very beefy convertible style X-brace. The convertibles came from the factory with a flimsy, stamped-steel I believe it was X-brace. The coupes have the mounting bolts drilled and threaded for the front but we had to use something called a "nutsert" and drill the holes in the rear of the frame to mount it. It cut a lot of clearance, but it really stiffened it up with the top off, and even noticeable when it's on. I don't think R&D Racing is around anymore. One mod I made to my 96 was adding replica ZR1 wheels to it. Even without the body work the 11" wheels will fit under the rear and the tires will come just flush with the fenders. The 96 Grand Sport came with 11" rears but GM used some stick on fender extensions to help hide them. I think it looks cleaner without, but they do fit. It definitely hooks better with the wider 315s on the back.

I had a black 1996 base coupe with the LT4 and I currently own a red 1990 ZR-1. If you can't feel the secondary valves opening up on the LT5 in a 1991, then they've likely been removed, wired open, or that car has been modified with a later ECM that has a smoother, higher resolution governing function. The secondaries opening should be very noticeable, it definitely has a kick at the point of engagement. My verdict between the two cars is that the LT4 is more playful while the ZR-1 is more serious due to the weight over the front end and more cantankerous power delivery of the LT5. That said, the LT4 doesn't egg you on with the throttle the way the LT5 does; by the time you get up to the former's 6300 rpm red-line it feels stressed. When you reach the 7000 rpm red-line of the LT5, it feels like there is more left on the table. Given that nearly 500 HP can be extracted merely by smoothing the airflow through the engine, without even touching displacement or cams, there definitely is a lot left on the table. An LT4 would need the GM hot cam to get there even with similar work done to airflow.
@RetroCarsForever9 ай бұрын
Interesting, I double checked exactly what the performance chip did at the 4:00 mark, doesn't look like it changed the secondaries function. I also checked with a few other friends who have ZR-1s who also claim their car has a pretty "linear" power delivery. It is a subjective feeling, but I also wonder if driving the car at a higher altitudes "smoothed out" the secondaries. Agreed with your "more playful" thoughts on the LT4. On a very tight canyon road, or on a tight autocross course, I do think it would be more lighter and more fun, and less intimidating. On the more open canyon roads that we drove on, the ZR-1 seemed to have the edge. And yes, the LT5 just LOVES to rev, it dares you to go faster in a way the LT4 does not! In any case, I appreciate hearing comments from someone who has owned both cars, thank you!

ZR-1 all the way. It is a significant part of automotive history. In the late 2000s, there were a few ZR-1's here on KZfaq doing high 10s all motor. That speaks for itself. Lingenfelter had a 640hp all motor ZR-1 in 1994, which only matched by McLaren in terms of natural aspirated power.

Great video, well produced thank you. For me the LT5 is the most beautiful motor GM/Lotus/Mercruiser ever produced..........full stop. LT5 holds a (showroom stock) world 24 hour endurance speed record averaging 175.885 mph covering 4,221.256 Miles. The LT5 sound is music to my ears. I looooooove the steel/blue color on the ZR1. I love all 92 and newer C4's.

Thank you! And agreed, as if the LT5 wasn’t enough being a technical powerhouse, it also LOOKS fantastic too.

as someone who owned a highly modded c4 they are downright scary when the power is approaching 400rwhp. imo the lt5 in the zr1 is the best engine they ever produced in this gen. extremely smooth and power comes on higher in the rpm range making it MUCH easier to handle coming out of corners. problem with the c4 zr1 is parts. it was hard to find parts 20 years ago for these. today? LOL i could not imagine,. plus, repair parts are expensive for that motor. c5 was a massive increase in frame stiffness and predictability when those hit in 1997. c4 really required soft tires to be even somewhat safe with more hp. back end really liked to step out. in hindsight they were actually more fun closer to stock. better balanced.

I just bought an 87 with the 4+3 has a ram air intake from the front license plate, a 3:73 rear and complete muffler delete directly behind the cat. And it's lowered with a body kit as well. She flies. I'm gonna add a cam, change the lifters, add some headers. It feels like I'm pushing 400hp right now but it's probably closer to 340ish. C4

Owning, racing, wrenching and still collecting the mentioned, your vid is spot on… but what the world rarely sees is the 120mph snd above difference in the zr1 vs many competitors people “think” are faster… AND the big one is endurance… the lt5 will keep going top speed long after the lt4 has heat soaked, thinned the oil and spun a bearing. When i started racing LT5’s… i would break other cars i attempted to push as hard. The world is not 1320 fr long or even 1 mile long. From coast to coast the Lt5 will run at 7000rpms non stop

Great Video, i would have loved to see them drag race. I always love your C4 Corvette content. Keep up the great work. Please make us a drag race video between the two cars.

Brad your videos never disappoint!! How has this never been compared before! As an LT4 owner a ZR1 is next!
@RetroCarsForever9 ай бұрын
Thank you! I was also surprised no one has done this comparo in 30 years...Especially considering the LT4 was essentially the replacement for the LT5. So I knew I had to do it! I'm with you, I think my next C4 has gotta be a ZR-1, preferably a late model version for more daily refinement and power.

The C4 ZR1's 'big hips' make it a clear winner in the looks department. While the LT5's Quad OHC setup has potential, I would take the LT4 in a heartbeat, simply due to aftermarket support, as minus the optispark, reverse cooling system/water pump and a few other bits and bobs, it's still a good old SBC at it's roots.
