I have a 2009 GXP coupe ( Mysterious black )

[/IMG]

( Down the road, I will consider if I want to swap for a V8 )

What's your opinion of swapping for a ZR-1 32 valve 4 cam
( I found one on Ebay...I'd have to have it completely rebuild top to bottom )

Would it work with the cars computer set-up -- I think it would look pretty good

Has anyone every put a non LS V8 in a solstice..I've see a 2JZ Straight 6
( that's not right IMO )
all I have seen is LS3 / LS2 / LS7 / LS1 I'd like to see a 1st generation ZR1 motor in a Solstice It would be something you would never expect under the hood of this car

If you want to drive it on the street, emissions laws dictate that the swapped engine be the same model year or later as the car the engine is being swapped into.

In your case the replacement engine would have to be a 2009 or newer. Therefore only LS3 or LS7, even LS1 and LS2 are too old.

:huh::dunno:

Oh yeah, it's going to be a demented sight, that's for sure and very special build. Good luck and have fun. Would be nice to watch a minute by minute account

You're driving a very special car. One of only a few produced. Why change it? It is what it is. It's got great acceleration and decent handling and braking and you don't have to do anything to it but routine maintenance. You will spend 10 or 12 grand putting that motor in the car with all the changes you have to make. And for what? A second or two in the quarter? Just so you can say you did it? If I had all the money I dumped into cars as a young man other than for no good reason other then how it made me feel I'd have quite a nest egg by now. Think it over. You want that kind of performance but a car that was built around that engine. You will enjoy it a lot more and you won't have the headaches that a conversion usually brings.

Hi there!

What's your opinion of swapping for a ZR-1 32 valve 4 cam
( I found one on Ebay...I'd have to have it completely rebuild top to bottom )

Would it work with the cars computer set-up
I once saw a ZR-1 engine, in the crate, sell for $15,000. Not "asking price", *sold*.

The short answer is that no, it won't work with the existing computers without extensive modifications.

The ZR-1 engine is a weird beast, very low total production, and parts are both difficult to find and expensive. Any hotrod parts that were ever made for it are probably long gone by now, or stupid-expensive. So, you're stuck at the ~375HP level without forced induction or nitrous.

As cool as it sounds on paper, it would be both a nightmare and a money pit to execute.

If I were wanting a unique DOHC V8 in the car, I'd look into what it would take to stuff a Northstar in there. You could at least find a 2009+ model year engine and have a hope of making the electronics work.

LT5's was an interesting engine in the day. Almost double the cost of 1990 Vette, by 1992 the LT1 was almost as quick for half the cost. So GM killed the ZR1. All the spare GM parts for that engine were scooped up by a few companies when GM said it was going out of production. There is a early and later production with a different HP rating, but were impressive then, down right low now. Looking online seems like it was tested stock at 12.8 which seems about right, I've run quicker in my Solstice and the Solstice is not quick by any means today. But will out handle most "performance" cars.

Would look "interesting" will give it credit there. More I think about the LT5 might be a bit long and too high in the front to fit. Oil filter is on the front of the engine. It's also a wide engine,

Your car will have kick-ass performance with a good tune, for just a few hundred dollars. Honestly, you won't believe the difference! Try it first.
If you need more power, you can make some modest changes to the engine and turbos and have scary power (but very streeable) for about $5k.
Why spend upwards of $20k to plunk a big heavy V8 down over your front wheels? You don't need it. I'm an old muscle car guy, but a well-tuned turbo 4cyl has converted me!

A built 2.0L + a hahn 20g and a 5th injector will net you over 500whp that has a very wide powerband.

See monadzbak for more details on the sky forum.

You can build an entire 2.0L project for way less than a V8 and make much more power. But you cannot replace the "v8 rumble" that so many crave. So its a matter of do you want the sound, or the performance?

Presumable the question is being asked because at some level your concerned/curious about what others opinions are.

No doubt a ZR1 engine would give the car a wow factor. However, engine transplants usually get two types of reactions; thumbs up (by folks who appreciated the work that was involved) or thumbs down by those who think if you wanted a V8 you might of been better off starting with a car that had one available. Also, keep in mind a lot of folks don't know (or care) what was even available for these cars. Basically, Kappa's are viewed as entry level sports car, not vette, muscle cars, Godzilla and European competition/killer's. Which means you can also take that as a challenge and prove them wrong.

Read or pick up the Solstice book and it will give you insight on what it's creators originally envisioned it to be (a nice looking, 4 cylinder, entry-level sports car). Having said that, I've always found it amazing that engineers always seem to make the engine bays of small cars large or wide enough for engine freaks to stuff or pretty much cram in whatever they want in them. It's almost as if they are saying; well that's not what the platform was primarily designed for, but we'll engineer enough room in the engine bay for those that do, because we know someone will eventually do it. Because most all true car enthusiast have a little bit of rebel in them. ;)

The GXP already performs well or has tunes and parts available to push it to compete with V8s (I'd argue at expense of longevity but that's an entirely different discussion). In addition, once you get into engine transplants territory you're essentially taking it into the custom and hot-rod arena. Which is fine if that's what or where your objective/passion is. At the end of the day it really doesn't matter what we think the only person opinion that really matters is yours.

I can't find where Jeb made over 500 to the ground thread on either forum. Can you provide a link? I would like to see the graph to compare it to a NA 571rwhp 6.6L V8 graph.

What is the cost of a built LNF with bigger turbo and the right 5th injector setup? So about for about $5000 you can have built LNF, head, springs, cams, pistons rods, machine work and new turbo setup with the 5th injector? Using the original engine to build from?

500+rwhp is impressive no matter how you make it, boosted 2.0 or a NA V8.

For sure, there is a lot of talk of dropping this or that engine into the Solstice, but not much of it makes a whole lot of sense. I love the 2JZ swap, just for the rare nature of it and the simple fact that he went out and made it happen. And of course, the LS3's are the best bets since they are emissions compliant and all the parts are out there to make them work. The old ZR1 motor seems like a nightmare since it is, well, old and the electronics would be nearly impossible. Plus, it is only 375 hp, which the GXP can make fairly easily. My old setup from Werks (big wheel turbo and supporting mods) made 400 hp, drove like a dream, and would likely leave a ZR1-based Solstice in the dust in every way.

Of course, now, I have a supercharged LS3, putting down 625 hp, which is a but over the top. But, it runs great, is actually a lot smoother than the modded 2.0 and is just a blast to drive (plus, that sound...).

Anyway, mostly these ideas are fodder for discussions on these forums. I don't really get a lot of the engine ideas, since many of them make less power than a lightly modded 2.0. The 2JZ build is unique because it is one of the great motors out there and can make up to 1,000 hp.

As I have said many times, the best idea is to get a good, used LS3 and T56 and a friend who is a mechanic and do the swap with Werks DIY kit.

He has not put it on a dyno yet, but I think he plans to in the near future once his tune is where he is happy... Like I said contact him for details.

However GMT said that he logs are showing loss of traction at 65mph in 3rd gear.... that pretty much lets you know where he is at :lol:


News flash---

As far as I know, my Sky has been the fastest/ highest hp LNF Kappa around (non running cars don't count. lol). I have just passed that honor to Jeb. The last few logs he's given me have had several 3.2 second 60-100mph times in them. He's breaking traction at 65mph in 3rd gear. There's no way he won't dyno at OVER 500whp/500wtq!

Breaking traction just means not enough tire on the car for the power it's making.

And yes I've done that before, coming off of VHT at the 1/8th mile at the track, top of 3rd with 3.42 rear gear, T56 and 28" MT drag radial. I'll let you do the math at what MPH that was at. Was it fun, nope, snapped the blower belt had to put it in the trailer for the rest of the day. On a set of Nitto 555 RII going to WOT at any legal speed if not in 5th or 6th was useless. Power you can't use is wasted. Been there done that, no fear of blowback making that comment.

So how much cheaper is building a LNF than a LS3 for about the same HP? Then you're always tethered to where is the next E85 pump in your area. Midwest it's great here on the east coast few and far between in my local area. I think most are on Navy base exchanges. Owning a diesel I learned real quick to know where you can/can't fill up at, out of town trips takes some planning over just driving a gasser where any gas station will do.

A nicely done engine swap is great, a built stock engine is great too. Happy or Glad both give you a warm fuzzy feeling.

This reminds me of the guy that wanted to put a 1960 era 283 into a Solstice. Why?

These cars have one of the most interesting engines going technologically, and unless you are all about nothing but having visual impact when you raise the hood, I can see no reason whatsoever to take 2 steps backward and stick an old tech engine in there.

Hey - tune the LNF and have a fake ZR1 plastic shroud that fits over the 4 cylinder and you'll get your visual impact and higher power to boot.....

E85 is not needed to make roughly 600whp. People have been making 600whp with evo's for years and running 9's on 93 octane.

If you are worried about "usable power", you should upgrade to a corvette or viper or perhaps a GTR/Evo with AWD. I thought we were talking about making power in a 4 cyl here....Everything CAN spin but it takes a driver to keep it in the grip department.

Also here is an evo with a stock short block, some springs/retainers, turbo and exhaust... runs 487awhp and still loses grip on slicks. Hmmm Usable power is again all up to the drivers skill level.

Jeb is on stock sized tires I believe, there's a TON more traction to be had with 275/45/18's on the back of these Kappa's. (Ask Elff, he's seen the light and drank the Koolaid on the Conti DW's!) And you also have to realize he's starting to break traction at 65mph, in third gear, just for a little bit, and still pulling off a 3.2 second 60-100. That's supercar fast. Here's the list of 60-100 times- 3.2 seconds is ahead of at least 95% of the cars listed.

60-100 Times :: TorqueStats.com

At my last dyno I put down 460/460, on my conservative daily driver tune. Torque peak is at 3500rpm, and still puts out over 440whp/320wtq at ~7300rpm. That's a helluva power spread. I have 275/45/18's in back and can hold traction fine in 3rd gear as long as the road is good. I've pulled off many 3.2 second 60-100's too, but I'm not taking my car any faster or going for more power for several reasons. Jeb's car WILL be putting down 500+ when we finally dyno it. His torque peak will probably be 1k rpm later since his turbo is different than mine, but his top end should be stronger.

Point is, traction on these cars is not a problem up to a solid 500whp/500wtq. Yeah 1st and 2nd can be crazy if you punch it, but it can also be tuned to hook up in every gear, EVEN 1st and 2nd. These LNF's can pretty much be tuned to do whatever you want them to do.
