Looking to find a ball park figure of how much my engine weighs with just block, intake manifolds, power steering braket and pump. any one got an idea i was think 200-300 pounds? somewre in there?

 

Well, the short block itself is about 200 lbs. The intake manifolds are about 30-50 lbs altogether. The P/S bracket is like 5 lbs and the P/S pump is around 10 lbs. You do the math. But if you want the long block assembly, I think that's around 700 lbs.

 

The shipping weight of my short block was 215lbs.

 

the engine with tranny, and all acessories should be about 450lbs.
no transmission it should be about 325lbs.

A complete engine with turbos and all accesories weighs in right around 400lbs.

The trans weighs around 90lbs IIRC.

Renesis 303 lbs
last generation rotary engine (FD REW) 344 lbs

This is pretty close to the total Scotty305 came up with adding up the weights chillin_rx7_guy posted in the thread above.

For comparison, a very light aluminum 346 c.i. V8 LS-1 weighs 390-400 lbs as longblock, ~460 lbs with assesories and 497 lbs fully dressed...

Sorry to drag an old thread up.

The ~400lbs I quoted was a fully dressed 13B-REW.

That estimate actually matches pretty well with your numbers. A LS1 converted FD will add about 60lbs to the weight of the car. Consider in the conversion you'll lose the cats, put in a smaller battery, ditch the IC and piping, etc so you'll lose some of the 90lbs added in engine weight and end up with a car that weighs about 60lbs more than stock.
