Also, +1 on grammar/spelling classes.
I know we had this discussion before, but I think who ever told me that information was just anti rotary.

I don't know the accuracy of the data I found online, but what I found shows the 13B-MSP to be 247lbs with all standard attachments. I take standard attachments to mean both manifolds, alternator, and a few other items?

I'm seeing between 400-500 for LS1's or LS3's. This is not to mention that it's got 6 more header tubes 4 times as much exhaust header flange, bigger intake manifold (that's probably not made of plastic), etc. It's going to have higher and farther forward CG. LSX will also need a larger transmission which will add to the difficulty packaging and weight some more. More torque = wider heavier gears. (Another reason why revs for HP beats torque, many of you would be shocked at the width of the gears in a Formula 1 car. There goes my shameless plug for power over torque)

With all that said, I'm all for the LS swap. 20 mpg on regular, 200 more HP, POWER (not torque) all over the rev band. One of the most fun motors I have ever driven. I don't think there was one person that sat in the car with me that wouldn't just have a huge grin on their face after the 2nd gear pull in a Corvette. Oh did I mention it makes cool noises? The 90 degree V8 noise is worth it all on it's own.

Sorry for not liking spoon feeding you. Plenty of people trying to tell you the answer. You just need to read and then do before posting.

There's a sticky thread somewhere on this board that had the weights of just about anything you can think of on the car, and if I'm remembering right it had it at mid 300's for the engine fully dressed but yah, I see I've eaten Zack's propaganda and a fully dressed LS1 is more like ~525lbs + 180lbs for the tranny...

But yah, if I bought an FD, I'd drive it until the engine pops (which it inevitably will) then LS swap.

First off sorry about your engine. That really sucks.

It's been a month and maybe you already have the car fixed or replaced. If not, read on.

If you have a place to work, etc. you can rebuild it yourself. If not, then salvage motors seem to run $1500 to $2500 depending on miles, condition and the seller.

But if you want it done RIGHT, not many folks with popped engines are as lucky as you -- close by not only to Atkins Rotary (Puyallup) but to Jerry's Little Car Shop (Kent).

Maybe you know this already but Jerry's been working on rotaries since the early 70's, including Mazda factory racers.

http://jerryslittlecarshop.com/history.htm

Atkins has been working on rotaries for about the same amount of time. Their website says they don't work on cars any more but they do quality rebuilt motors. Look what I found on ebay:

http://cgi.ebay.com/ebaymotors/MAZDA...ts_Accessories

You might want Atkins to build a tougher motor since you have a turbo, but then again you can recoup a few bucks at least by using your old engine for a core. If it were me I'd spend the extra $$$ on porting and engine balancing, and whatever can be done to a RENESIS to make it more reliable.

Doing an LS swap will give you potentially WAY more power but you'll throw the car's balance off. It won't feel the same and it won't handle the same. If you're into big power numbers maybe that's a trade-off you're willing to make. But if you go with a converson kit like the one Hinson is developing, you'll be out just as much $$$ as if you got a rebuilt engine and worked through Jerry's.

Whatever you decide to do, good luck to you.

Cheers,

Aaron
