ka24de for sure even with bolt ons the ka24de can make 190-200hp
eg. jim wolf cams, headers and piggy back tune.

I'm pretty sure that u wont get an sr20det engineered,ca18det yes.Although I'm talking about the coversion into a ute,might be different for a coupe.Oh you are in the states,thats a different ball game altogether.

I'd go for a 240SX motor, you can find a cheap non-running 240SX complete with 2.4 liter motor, 5-speed, wiring and ECU. The SR20 crossmember works with the 2.4, it's a bigger motor, less expensive, more reliable, can buy parts anywhere, a lot less work to fit

A12: 58 hp
KA24DE: 156 hp
SR20DET: 205 hp import motor

KA Engine Swap

So I'm fairly new to the Datsun scene I just got a 72 Datsun coupe Roller no motor no tranny... I want your guys opinion on what is a better route?
Get a A12 motor and tranny and do mild upgrades for a easy swap
Or
SR20 turbo swap the car for more power out the gate?

The car was an automatic so it has room for the SR20 and has a custom crossmember for the swap... I just read that it will cost a lot of money to get any type of power out of a A12 compared to just buying a stock SR20DEt with everything and just putting it in? I know I will need a lot more for the SR20 swap to convert it as well if someone could shed more light I would appreciate it... Also the SR20 motor is heavier so will it throw off the car a lot since the original motor was lighter? What can I do to fix that of I went that route?
