JDs78 Posted August 19, 2017 Share Posted August 19, 2017 (edited) Today will mark the day in which I start my ls swap on my 78 280z. I resently sold my 09 ctsv that was making 750 to the wheels wanting to make the same power but in a lighter body .The car was resently painted yesterday in which I will finish up and then pull the motor. Should have pulled motor first I know but o well. My goal is to have a fun Street car making 7-800hp. Motor wise I am still indiscive about which to go with 4.8 5.3 6.0 as well as transmission. Your input would be greatly appreciated! Edited August 19, 2017 by JDs78 Quote Link to comment Share on other sites More sharing options...
trackzpeed Posted August 20, 2017 Share Posted August 20, 2017 7-800 hp is a handful of a street car.... Your Datsun chassis will need some reinforcements with that kind of power not to mention brakes, suspension, axles, etc..... Personally I'd plan everything else before that kind of motor/power, but I always enjoy reading another build. I'm running an NA 5.7 LS1 T56 6 speed and it's a riot on the street and track at 1/2 the power you're shooting for. Good luck, this is great place to start your research.

G-Tech Posted August 21, 2017 Share Posted August 21, 2017 nice color! i agree with trackzpeed, my ls swap is 400whp and any more and im just spinning. but more power to you if thats what you want. if your boosting it pretty good i hear all kind of good things about the iron 5.3. if you want to mantain the great weight balance then go with the alum 6.0. also on a budget, the 5.3 iron is alot cheaper. but if you can afford it i say the 6.0. goodluck!!! they are a fun car to drive with LS motors.
