  77 620 Motor Swaps?????


yo guys kinda new to this nismo thing but i picked up a 77 datsun 620 the other day n got her running
meow im kinda wondering if there is ne thing that swaps into a 77 datsun 620 ne thing easy??? such as something that might keep the stock tranny but get me some bang for the buck havent checked the motor code on her yet to see wat im dealing with
secondly is the stock motor even worth wasting time on a performance rebuild on the stock motor??

A couple motors come to mind. Most popular would be the SR20DET. You can also fit a KA24 in there. I have seen Chevy 350s in there. I bet with some fab work you could squeeze a VG30 or L28 in there. Some have fitted the RB series in there as well. It's all about $$$$$$.

He said something to bolt to the stock transmission.

You probalby have an L20 in that thing. The 280Z's of the day used an L28 - similar in almost every way to your motor, but 6 cylinders instead of 4. '75-78 L28s were fuel injected. If you want to have some real fun, find a turbo motor from an 82-83 280ZX. While it might bolt up, the little truck tranny might not be up to task there.

You'll also have some issues with block length and will likely need to modify the radiator, and run electric pusher fans instead of a clutch fan.

KA truck engines drop right in, and if you locate a Z series five speed you can bolt its front case onto the rear case of the L transmission. I have done the swap myself into a 620 using a 240sx KA and tranny but it was a bit more work.
Anyway, theres more info over at IpromiseIwontTroll.com peace.

if money is an issue then do the KA swap. Its cheaper and by far the easiest of the above mentioned. peace.
