Ls7

[red_dog007]

I know that this is more a question at hybridz, but I don't like that place and don't even want to do a search there.

Anyways, I was thinking, there are a lot of Corvette's with middle aged men in them in their midlife crisis. I hope that I never become one of these guys. I have always wanted a 280zx 2+2, but I might meet the Corvette half way. I know that an LS2 can fit in a Z car, but I want more then just an LS2. I want 105hp and 70ft.lbs more torque then an LS2. I would want an LS7 dropped under the hood.

Anyone know if the LS7 would fit? Its supposed to have a different block then the LS2, so I am not sure if it is going to be too big now.

If it fits, I sure will be looking forward to my midlife crisis. :devious:

Any thing will fit. I've seen 502ci blocks dropped in them. And yes it has all been done, ls1 ls2 ls6 and ls7's. it is all on hybridz. so bite the bullet and check it out!

oh but don't put it in a 280zx 2+2 that is just ugly madness, you are losing all you performace to weigt not to mention they look like a grocery getter!! Stick with the 240z's and gut in to just what you need, that will make your HP go alot further!! Do what I did, all I have is a hallow dash and one Aluminum Kirkey race seat. no speakers, radio, heater, a/c, power steering, nothen all of it is gone! saves tons of weight, and get rid of those heavy seats too if you want to do it up right!

Red_dog, the reason you don't like that place is because they told you to search. They expect people to search first and then ask questions. Yes, they can be a bit rude, but they even state that in their forum posting rules. They ask that people have a thick skin when reading posting/reading comments because some folks may come across badly.

The best place for information on this swap is Hybridz.org, hands down.

I agree with Chris on the zx 2+2, they're just ugly, IMHO. If you want a 2+2 for the extra space and fake seating, get yourself a first gen 2+2-the lines are neat and clean, they still have a classic design.

Don't tear me to pieces if i'm not right here, but as far as I know, the LS7 is the same as an LS1 or LS2 but the block is different and it has better heads. Basically, if you can bolt in an LS2 that means you can put in an LS7. Why on earth you would put it into a ZX 2+2 is beyond me. This guy was able to get an LS2 into is 280Z very nicely, so im sure putting in a LS7 can't be all that much more difficult.

JUST PLEASE PLEASE PLEASE PLEASE DON'T PUT A MOTOR LIKE THAT IN A CAR LIKE A 280ZX, A 280Z WOULD NOT BE TO BAD, BUT STICKING WITH THE LIGHTER BETTER LOOKING 240Z IS BEST!!! I WOULD LITERALLY CRY IF YOU PUT IT IN A 280ZX 2+2!

Whats wrong with a 280zx 2+2. I forgot that it also has to be T-Tops.

The 280zx 2+2 w/ T-Tops has always been my favoritist Z car. I have been looking at them for 3 or 4 years, and it has still been my favorite of them all. Plus why is weight mattering here? With 505hp, the car is still going to be lightning fast!!!

Plus I already got my 240Z all planned out.

Either a 280zx 2+2 T-Tops w/ LS7 or a Viper SRT10 as the midlife crisis car.

Hmm So what is there to think about, Dude go with the Viper. I don't know if you have ever driven one but the older ones are not designed the best IMO, it feels like you sit alittle weird in your seat bc of the tranny. BUT still hands down no comparison the viper WAY WAY over the 280zx!!!!

For all the reasons previously stated don't do the 2+2, any of the V8's will fit with little difficulty. Your only real delays will be deciding which motor and the time invested in making it look and perform correctly. As for turning middle-aged, you will, its as inevitable as taxes. As for being middle-aged and driving a "Vette", well that's up to you and what you do with your life between now and then. Saw your website, good job on what you've accomplished so far. Looks to be an excellent choice for a V8 conversion / "Vette" eater ().

280ZX 2+2 is not my fave Z, but if it suits you, DO IT! ought to be one kick arse ZX w/ an LS7, sure would surprise quite a few folks.
