So if you were to build a dedicated auto-x car then you obviously wouldnt opt for an lsx. Uneeded power, uneeded weight. Compare that to a touring, dift or drag car and that 126 lbs extra of an LSX wouldnt be as big of a deal when you look at the stock power, potenial power and reliablity it brings with it > > Still if anyone here’s racing competitevly enough to be contemplating an LSx Vs. an extra 126 lbs, I’m pretty sure what we say isnt going to make or break their decision. 400hp out of the box that gets 26+ mpg, incredible reliability and cheap bolt-ons sound good to me for a street and/or track car. I agree you don’t need all that power, but it’ll make up time it straights that you’ll most likely lose in the corners. I’m not build a “dedicated” autox car, but my S14 will be doing far more solo1 or 2 than drifting. And an LS2 is waiting to go in. The power of an LS1 easily over poweres the weight. 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. --- _[View the full topic](https://forums.speedlife.net/t/ls1-in-a-240sx/119673)._
