I am in the home stretch as far a putting a pair of turbos on a 383, and I have several observations and biases. As appealing as an LT1 and even the LS1 is, Grumpy is right. You can't beat the bang for the buck of a first gen motor, and if you don't spend the money on making your bottom bulletproof, your motor is going to go bang. The higher compression of the newer motors argues against them, although the reverse cooling and aluminum components helps out here. You could resleeve an LS1 and add lower compression pistons (LT1 also), but the budget gets eaten up. Advanced engine management (I'm using an Electromotive TEC3) will be especially helpful in preventing detonation with these higher compression motors. As for which intake to use, well you're asking for about 700 hp which your setup should should be able to make without breaking much of a sweat. So does it really matter? You'll be at warp speed in the blink of an eye . All kidding aside, yes, the LT1 intake does give you higher top end than a "stock" stealth ram, at the expense of a little bit of low end. See "stealthram.com" for a comparison of the two. The LT1 peaks at a ridiculously high RPM (more in line with my RX7). Still, it is an appealing alternative to a Stealth Ram if you can get one cheap. You would need to modify it for use on a Gen I motor (see http://www.lt1intake.com for directions), but it's not hard or expensive. I'm going with a Victor Jr. style intake set up for fuel injection for now. One of the most difficult problems I have had is coming up with suitable exhaust manifolds. Many people have bench raced on this board and said "sure, there's plenty of room, you could put it in X location without any problems". Unfortunately, I've come to the realization that turbos and all their plumbing take up an awful lot of space, and there's not really a lot if space in the engine bay for it. The Turbomeister has done it, and placed them in front of the block. I've elected to place them to the side, just lateral to the valve covers. This allows me to swap out turbos easily if I want and helps the weight distribution (remember, we speak polar moment of intertia on this board). I've tried many different manifolds, and eventually had to make my own. I'll be posting pictures soon. By the way, Corvette LT1 manifolds flipped over look like they will work, and I'll be getting some soon. Good luck and let me know about your progress.

Mike, Your wife sounds really cool. Maybe I should work on her and convince her that that spare LS1 in you garage needs to be gotten rid of once your supercharger project is done .

I had a first generation MR2. Remember, it originally came out as a commuter car. Overall, it was the best car I have ever owned. Handling was awesome, and performance from the motor was ok once I put on headers and a new intake. Better yet, my insurance company didn't consider it a sports car. They can be had really cheap. As for the Fox body thing, how about a non-hatchback LX model with a V8. I'm sure he could get it past his parents as a non sports car, and they are really cheap. Actually, they perform better than the GT models cause they are considerably lighter.

Mike, I was just kidding-my life would be in mortal danger if my wife found out about any plans for yet another engine swap. The thought has crossed my mind, though. Maybe I could do it in secret so she wouldn't know. I could tell her the rotary blew up and replace it with an LS1. She wouldn't know the difference between the 2 motors if she saw them side by side [/url]

V8 Fox body Mustang. Best deal for the money today.

If you're building a new motor for a SC, can I have your old LS1 to put in my "new" '93 RX7-my wife got one for me for XMas? Love her. I like the TT motor, but I'm told they tend to grenade past 70K miles, so I'm overdue (at 80K miles). I know it's a swap that's been done before, and at 2800 pounds, it should be fun. On the other hand, the last thing I need is another project car!

It's the answer to my prayers. I really do believe that the R200's limits have yet to be tested (although I will try), and the axleshafts are the real weak point. I've switched to turbo CV halfshafts, but I'm skeptical about whether they will live in my application. If I break one, I just may give them a call. Thanks

From the title of the thread I was expecting something really primitive. Instead, you've come up with something simple that works, yet looks awesome as well. I love good fabrication work. Good job

I didn't know you had updated your site. Great work! Your wiring looks exactly like mine. I don't know why I decided to toss the old wiring harness-there were only a couple of circuits I didn't understand. I got a Painless harness, and it's not exactly painless. To make matters worse, the parts of the original harness I didn't understand I now realize I didn't need. Oh, well. Live and learn.

I had no clue Lingenfelter and Moser died this year. I have one of Lingenfelter's books, and it is great. I'll miss them both.

I thought it was the Turbomeister doing a peel-out with in twin turbo 383. He drives much too fast for a man his age.

After the Lorena thing, I read an article about how it was a worldwide taboo for jealous wives and girlfriends to cut off your Johnson if you stray--Thank God. There's only one exception. It's very common in Thailand, so the plastic surgeons there have become the world's best at putting them back on.

Which brings me to the second part of my question. Does it really matter how good your intake setup is if you are going to force feed it? After all, you could get more CFM's flowing through it by cranking up the boost. By the way, do you like my new avatar or did you like my last one better? I had planned on changing them weekly, but I find it hard to move on to a new avatar when the one I'm using at the time is so yummy

I will do my absolute best to test the limits of the R200 (with a 383 twin turbo). By the way, I've converted to Ross's CV half shafts, but can these be beefed up as well?

Has anyone here actually used the Holley Stealth Ram that Grumpyvette talks about so highly? He found one at Fasterdeals.com that comes in at just over 9" higher than the block. Supposedly, a TPI setup is a hair taller than this, and some of you are using these. Theoretically, then, a modified Stealth Ram should fit, but you never know. I don't want to commit to this if it won't work. An alternative to this would be a TPIS Miniram, but I'm not sure this would be much of an advantage. My current TPI setup includes 58mm throttlebody, larger runners, and is ported, so it flows about as well as a TPI system can. Besides, this is on a turbo setup, so does it matter how much it flows naturally if it is going to be force fed?

If you read Pete P's article on unibody reinforcement and install a roll cage, you should be fine as far as being able to stand up to the G forces a catapult would subject you to.

I think Phantom and Wheelman are on the right track. By using the height of the deck, you can figure out how long the car will remain airborne. To figure oute how far it will go, you need to figure out the velocity (distance =velocityxtime aloft). Remember to add the forward speed of the carrier. To figure out the speed of the car at takeoff, we need to use the 2 formulas Force= massx acceleration, distance=1/2 acceleration x time squared. I'm not up to the last one right now cause I'm medicated with flu medication, but once you have the acceleration and force parameters figured out, you can figure out the speed of the datsun at the time of takeoff from the deck and go from there. It's a lot faster than an F14

Most any equipment rental place will rent one out, but usually by the hour. Unless you can get the motor pulled in a hurry (i.e. get everything unhooked ahead of time), you might save money by buying one for $199 at Autozone, or $149 at Harbor Freight

Any attempt to rent a crop duster in the dead of winter is sure to get a call from the Department of Homeland Security!

Victoria British is great. They are based in the midwest, and if I put in an order in the morning, it's at my front door the next afternoon.

I just wanted to comment on an observation. Her breasts defy the laws of physics. Do you remember from junior high science that objects fall at the same rate regardless of size? In other words, a bowling ball would hit the ground at the same time a pebble would if they were dropped from the same height, even though one clearly has more mass than the other. If you look at the video clip (I'm using this as a flagrant excuse to look at the video clip over and over again), you will notice that her left breast "hits the floor" sooner than her right one. Go figure.

Gadzooks, those are real! By the way, like my new avatar?

I am drooling over those. I do they have removable lenses? I take a ton of photographs every day (sorry, not allowed to show them on this family oriented forum) and I use an "ancient" Sony Mavica that uses floppy disks. The good part about it though is that I don't have to spend a lot of time cataloging them in a computer (you see one set of perfect boobs, you've seen them all, right?). My resolution is only 640x480 and it seems to be fine. I'm not state of the art in the megapixel wars. It seems to work well for me though. All the photos in my personal gallery were taken at this resolution, and they are pretty clear. Still, those new digital sure are nice.

Hanns, That's pretty much what I imagined how you would build a manifold like that. It's simple, tucks in closely to the engine, and welds up easily without having to fishmouth round tubing. Sometimes the simplest is the best (actually it came to me in a dream, and I was pleased to hear that you had made one like I had imagined it)

Santa, I want an independent rear suspension that will survive the punishment that a 383 twin turbo chevy can dish out
