Might I add the LS1, when all is said and done, will weigh more than an extra 126lbs. > But the power makes up for it. > I will add this though. The LS1 was made for cars that easily weigh approx. 700lbs+ heavier than our cars. So adding 200 or so lbs to a car that is already approx. 2600-2800lbs (pending on lightening mods) isn’t a bad thing. > > BTW. > LS1 series motors never made more than 350hp out of the box. > The carvettes had 350 and the fox bodies had 305. The extra power comes from the ecu not the engine. > LS2’s are rated at 405 I believe. > The lS1 is reliable. It’s just not as reliable as everyone seems to think. My friend works for GM… You won’t believe how many LS powered cars are in there getting fixed. So for the most part it seems like we’re arguing on the same side, there we go. And I was meaning an LS2 when I gave the Hp ratings, I’m contemplating an Ls2 swap as well as I have one readily available to me, might be a while still until it sees the time of day though, lol. It is a piece of Gm engineering so obviously its not going to be perfect, but 400hp out of a Ls2 vs. 400hp out of an sr or ka, I’d say the Ls2 would win in reliabilty. --- _[View the full topic](https://forums.speedlife.net/t/ls1-in-a-240sx/119673)._
