1960s Nissan/Datsun U20 Engine 

Nissan Comp offered a number of performance parts for the U20 including intake/carbs, 7quart oil pan, a few cams, rods, pistons, flywheels etc. Not as much as for later L-series engines but still useful. The original engine was well built to begin with. I run a modified (to reduce compression but more than stock) set of Arias forged pistons, ported head, crank fired ignition (by Megajolt via Ford EDIS), a custom Isky cam (256 duration at 50housands, 531 total lift) and Dellorto 45DHLA carbs with 37mm chokes. Unfortunately it was running stupid rich on the dyno (10.5 to 1) but still produced 140hp and 135lbft torque to the wheels. It's a very streetable engine though compression is a bit high. I'm in the process of converting to EFI via Jenvey Heritage 40mm Weber DCOE look alikes. I expect better overall throttle response, wider torque band and likely a few more horses with better fuel control. The engine featured has solved a few problems the U20 has, namely the rear main seal, and I expect it makes very nice and use able power. It's nice to see that someone took interest in building this engine and featuring it... thanks.

Well here we are 3 years plus later waiting to see this so called great build run. So far just silence.

Look at these grown men fighting over a Datsun!! You sound like the guys from NW DROPS.

Clearly you didnt do much searching online as all of the engine parts and gaskets ect. are available at Datsunparts.com. ISKY still does custom or race grinds for these cars. Also the 2L motor was not originally made for a forklift it was the R16 that was a modified H20 forklift. The hp was 135 stock for the 2L unless it had the optional solex setup.

There is a ton of parts for the roadster there is a company in surrey bc that rebuilds them to better then new

I have a 1967 Datsun that my grandma and grandpa dated in while he was in the service, now that i took over the project i need the motor rebuilt and trans so i can take them on a date night in her. If you can help please its the original motor and trans

#Nissan for the win!

The solex carbs are a better choice for the u20

the U20 head didn't need any porting

not without a turbo

So if you finnished it where is the proof? Or did you not finish it. Like Sin city said parts are available .No proof of run sheets . A lots of hype no results to speak of

knee san NO Niss an say it with me freaks lol...
