This weight is WET and NO exhaust manifolds. ![http://vorshlag.smugmug.com/photos/142053457-M.jpg](http://vorshlag.smugmug.com/photos/142053457-M.jpg) Source [http://forums.bimmerforums.com/forum/showpost.php?p=9949714&postcount=41](http://forums.bimmerforums.com/forum/showpost.php?p=9949714&postcount=41) The T-56 weighs in at 125lbs. 609lbs - 125lbs = A motor that weighs 484lbs And for the record. User, “Fred Allen Burge” on zilvia once weighed and posted pics of the KS, SR, VQ (on scales, but the pics are long gone) weights that were dry with no exhaust manifold, but all accessories, and they all weighed 330-331lbs… With no transmission of course. STOP WITH THIS LS1 IS LIGHTER THAN A KA BULLSHIT! Case closed. ---

how whats the weight difference between KA and LS1 though? Must’ve been close if people kept saying LS1 was lighter. ---

Even at wet vs dry, the LS1 is only 154 lbs heavier, for how much more power right out of the box? Also I’ve never heard someone claim an LS1 was lighter, considering it’s twice the size (cylinders) of KA. ---

I hear all the damn time… Look on every major 240sx forum, look on youtube for all the LSx swapped 240’s… You’ll see over and over “The LSx is lighter than the KA too!” I never said there was anything wrong with the power to weight. > [@Londonmax](#): > > OP, why do you hate v8? Ummmm… I have one… Well I did… Albeit the cast version which is 74lbs heavier… Just never had it in and running because T56’s are too fucking expensive… I far from hate the V8. I’m just sick of all the arguments that people make. “It’s lighter because it’s aluminium”… I personally don’t give to shits about the weight. Find me a 6BT and NV5600 and I’ll try and shove it into an S-Chassis if it made any sense at all… (6BT’s blocks are roughly 1200lbs) All this thread was for was to put an end to the debate with actually supportive facts. Nothing more. I do NOT hate V8’s. ---

> [@Chad Dugan](#): > > I wonder what an LS series motor with headers weighs vs an sr or ka with a turbo set up and intercooler etc, gotta be within 150lbs? 150lbs is a lot though. Not really close enough in weight to say they weigh the same. Or even close to. > [@spd-dmn](#): > > yep > > you add a turbo, plus all the plumbing and accessories, and the gap narrows > > true story The accessories and turbo aren’t going to add 150lbs… I wouldn’t really include plumbing either. Simple fact of the matter is that the LS is heavy… Having twice the pistons, con-rods, heads, exhaust headers, and even a beefier crank, will almost always add up to more weight. ---

…and what the F does it matter when no one on this forum, or most forums, is a good enough driver to ever ever ever feel the difference the weight makes. Myself included and I drive one. Fuck, such a stupid argument. Weight this, distribution that, balance this, nuetral that. Just get in a car and fucking drive you losers. ---

No one ever said anything about weight distribution that, balance this, neutral that. It’s an argument I see a lot. I simply provided some facts. I didn’t know it was such a bad thing to clear some misinformation. I guess I should apologize for that? ---

I didn’t say it equals out just that the gap narrows obviously the LS is gonna be heavier. i can’t even believe that’s an argument somewhere but with all the different numbers thrown around for engine weights… dry, wet, this accessory, that accessory… trans on, trans off… i’ll believe the weight difference when I see the #s in front of my own eyes, using comparably equipped engines true story ---
