kingandrew Posted April 14, 2013 Report Share Posted April 14, 2013 i was looking for a truck and i came across this datsun 620 and i was wondering what i could do to build up the motor. i did a little bit of research and i thing it has the l20b. i am going to be using it for my daily and im not really going to baby it, so i was wondering what i can do to get a little more hp than stock but still be reliable. im working with about 2k. thanks Quote Link to comment
Jayden71 Posted April 14, 2013 Report Share Posted April 14, 2013 There is tons of info on this site about building a nice L engine. Quote Link to comment
Ratwagon1600 Posted April 14, 2013 Report Share Posted April 14, 2013 There's a thing called a search button in the top right hand corner, try that. As Jayden said, there's a tonne of info on the site, pls search for it so us old hands at building engines don't have to repost things for the gazillionth time. It gets boring and tends to piss us off! You may also want to consider reading this book. http://www.amazon.com/Modify-Your-Nissan-Datsun-Engine/dp/1931128049 Now before you get flamed, you may want to, i.e. "DO", post an intro thread with lots of pics of your ride. / nice Ratwagon 1 Quote Link to comment
datzenmike Posted April 15, 2013 Report Share Posted April 15, 2013 Since all L and Z series motors will cost in the neighborhood of $1,500 to rebuild, (much less if you do some of the assembly work) Why not get a Z22 block and rebuild it? Use everything from your L20B but the block.... head and manifolds oil pan, timing cover, distributor and engine brackets. You instantly have a 'stroker' L22B. his will run a 9.84 compression and will make way more power than re-building the L20B just from increased displacement alone. Quote Link to comment

Mike can you supply some more information about this? I am currently taking a L20b out and this sounds like something I want to do to it. Quote Link to comment

On my phone so won't feed you a link, but Google ratsun.net lz22 Basically find a good complete z22 block with internals. Swap over head, pan, timing cover, dizzy... Everything but the block pistons crank, from the l20 to z22. Instant awesome. Quote Link to comment

Sealik Posted April 15, 2013 Report Share Posted April 15, 2013 For a few more bucks....<......and HP You could bore the Z22 out to 89mm/Z24 or KA pistons LZ23 Quote Link to comment
izzo Posted April 15, 2013 Report Share Posted April 15, 2013 ^^ haha I mentioned that to him in a PM once I got to work! Pointed him to the Jason Grey info Quote Link to comment
jvb5577 Posted April 16, 2013 Report Share Posted April 16, 2013 Think I may just go the LZ23. Figured since I am doing it might as well spend a little more. For the Z22 block has anyone had luck at picknpull with engines? Quote Link to comment
Dawa Posted April 16, 2013 Report Share Posted April 16, 2013 wtf. NOW i learn about this? Quote Link to comment
