Here's a pic of the cream puff. Original paint on most of it and a really clean original interior.
The na ecotec weighs 350 lbs an LS weighs 390.
thanks

Nice looking sedan!!! Are you putting the ecotech in? I am starting to believe I should have jumped on the turbo ecotech I was offered for $3500.00 last year from a wrecked Soltice GXP. I think it would have made an interesting performance car out of the Astre Formula.

Awesome! Welcome to the board! Can't wait to see the result.


Your Cadillac many years ago is still one of my favorites. That was the inspiration for the 72 Buick I did!

Jeff,

I looked at that car when it was in Wonder Lake...in fact, when you gave me that lead on that LT1 engine. That is a solid car to start with. I'll stop by the shop and take a closer look sometime.

im doing a supercharged eco tec in mine

hmmm trunk model , not my fav looking body but they are a little more structurally stronger than the rest

cant wait to see the crazy stuff you guys do to it

With a supercharger or a turbo the ecotec weighs the same as an LS1. And I already have most of an LS1, we're probably gonna go that way.
Since the Goodguys autocross events are real short parking lot courses, we're probably gonna run a TH350 trans.
The first build will probably be fairly mind with bolt on's and some minor paint work on the decent original.
Maybe later a chassis, minitubs and 335's out back.

For making easy horsepower, the LS is the best choice. That swoop has been done before, and is very doable. I haven't seen a Ecotec swoop yet which I have recently become a fan of. There are a few advantages the the 4 cylinder. Cooling, steering clearance, and exhaust are just some. Not to mention room to work on the engine. Either way I can't wait to see what you do with the car. Not sure I would call 335's mini tubing though. Seeing that 225's are the larges tires you can fit on the stock front end, 335's may not give you the best handling balance that you are looking for. Now if you would like to make one of your custom chassis/suspension kits so you can mount 295's front and 335's rear that would be cool. Not sure that would leave you enough from for a V8 though. Welcome to the world of small hot rods!

Another build to fuel my internet addiction!

Jeff, I realize you're busy as hell with client builds and getting squared away in your new shop but if you get a moment or two maybe you could check out the suspension forum. I'm sure there is a lot we could learn from you and there would be no shortage of willing students.

I'd love to see a full frame and a weight less than 3000 lb's. An LSX and a 6 speed with 255's and 275's would be great. I would spend my savings on it.

Bill

just think IMSA vega , that would allow for 295/305's in the front , LOL

now that would be sweet

Interesting project.

Uh ... are we comparing apples to apples here? I don't think an LS1 weighs just 40 pounds more than a non-charged ecotec. The weight difference is about 120 pounds.
Still, it's lightweight and a good choice. Are you planning to convert the LS1 to a carburetor or stick to the fuel injection?

The LS1 does weigh in the 390 to 400 lb range. The iron block LS motors weigh about 90-100 more. I'm not sure what a Ecotech weighs.

Bill

full dress weight is under 300lbs

I found this on the web from a guy who put an LS1 in a 911 Porsche

Here is the information from Toyjet


Quote:
The factory 1980 Porsche SC 3.0 liter engine is 178 hp @ 5600 rpm and the torque range is 175 ft/lbs @ 4200rpm. Top speed with stock 1980 porsche engine 139 mph. with 3.88 rear end gears.

The LS1 Corvette engine is 350 cubic inches (5.7 liter), 345 hp @ 5600 rpm, and have a torque range of 350 lb/ft. @ 4400rpm. The LS1 Corvette engine (equipped with a supercharger and 27 inch tall tires at the rear) will enable me to go 184 mph in fourth gear. However, with no roll cage, I limited myself to going 155mph. with a 240lb. witness in the passenger seat.

The quarter mile time ran thus far (11.94sec at 114) mph. was done with a conservative take off at the starting line because of the weak stock axles. (refer to my Custom page to see the actual quarter mile test and tune video of my first successful pass using stock axles at Houston Raceway Park). I now have a set of re-engineered axles that can easily hold up to the challenge of high torque and high horse power.


I weighed the 1980 911 3.0 SC engine and 2000 GM LS1 Corvette engine and this is what I found out: My fully dressed 1980 3.0 Porsche engine ready to install weighed 472 lbs. Factor in the weight of the oil in the 10 quart oil tank mounted at the rear of the vehicle needed to support the 3.0 engine, then your engine plus oil tank weight jumps up to 490. 5 lbs. at the rear of the vehicle.

(One gallon of oil is 7.4 lbs. Ten quarts is 2.5 gallons, 2.5 x 7.4 = 18.5lbs. 18.5 lbs. + 472 lbs. = 490.5 lbs.)

A fully dressed 2000 LS1 Corvette engine ready to install with the engine computer and wire harness, complete exhaust system, engine mounting brackets, AC compressor, alternator, custom water pump adapter, transmission adapter plate and flywheel weighed 434 lbs. This is a rear vehicle weight savings of 56 lbs. over the Porsche 3.0 engine. I did not weigh the above engines with the transaxle or clutch assembly bolted to either engine. These parts would be used for both installations and their weights would obviously cancel

Hope to have the LS engine ready to go in a week or so.
Putting a th350 in it for now.
