However, the benefit to the LS1 is that I can make that power with little money. Intake, exhaust, fuel pump/regulator, and a little bit of spray on occasion. If the LT1 requires more to make the power reliably (i.e. internals - rods/pistons,) I’ll nix it. > > Let’s hear some power production tips. LS1’s respond well to bolt ons, ie headers, exhaust and whatnot, but both motors are great starting engines. I am more fond of the LT1 because its an iron block, and get one out of a vette and its a 4 bolt main. Also the LT1 has insane lowend torque, but the LS1 has a much better higher end. Also during the build you have to think if you need to stay emission legal or not. a cc305 will pass emissions here, but a cc306 wont last i heard. But if you are OBD2 then you can just reprogram to make it say it passes, unliek me who gets the sniffer. If you dont have to worry about emissions the id just buy the LE3 package for the LT1, upgrade your injectors, fuel pump, a few other things and your money. > [@GTI \> lancer i believe.](https://forums.speedlife.net/t/gti-lancer-i-believe/20605/98): > > is there any kind of programing out there for the LT1.i no there is for the LS1.other then full exhaust and intake ne other bolt ons out there that would help? only thing for the LT1 is a hypertech which isnt worth the money. Best bet is to get ahold of pcm4less, or madtunz (i think thats their name). Or you could just get a dyno tune. If its just CAI, headers, exhaust, and maybe some other small things pcm4less is perfect, but when you get inot heads and cams, and all that good internal stuff id go with a dyno tune. --- _[View the full topic](https://forums.speedlife.net/t/lt1-guys-need-some-help/187600)._
