ok i have a 1976 Datsun 620 4speed... it is currently my beater but the engine is well on its way out with about 270K miles on it (im getting about 8mpg now).

so im wanting to go with a SR20DE set up in RWD w/ a 5speed tranny... did Nissan release a RWD SR20DE w/ 5speed or am i gona have to get a FWD SR20 and use a DET tranny w/ custom manifold???

also would be interested in anything else that might work for this situation... want it to be 4cyl, NA, and RWD w/ 5speed. let me know

Finnaly another member with a 620. Check over in 240gen for more info on the SR20DE. I dont think anything was released in the uSA using a SR20DE. Also i think trying to use a FWD SR is going to be harder than you think. There are other ways to go on the swap. You could try a KA24(D)E, as they are very easy to find here in the USA. Maybe if you want to keep it old style try finding some carbs/headers and all that kind of stuff for the L20 motor. 270k is doing good on a L20, just give her a good rebuild and drive it another 270k.

Post pics of it soon.

If you dig through here you will find a thread on my 620 trucks.

the SR20DE came in us models of the NX2000, Sentra SE-R and the later 200SX (all wrong wheel drive) and also came in one of the infiniti's but not sure which model and which wheels it was turning

G20, FWD.

Does this mean the SR20DE was never brought over in a RWD platform??

I fail to understand the logic on going to the econo SR20 seeing that if you spend the same $$ on building the L4, it will kick the SR20's ***.

Why do you see so many L4 engines stuck into late modle Nissans at SCCA events ?

I am just gathering parts for my L18 that sits in my '74 620 engine bay.

So far I have a mild street cam (268), 40mm side drafts, headers, Big valves, and a few ignition parts. I did a similar set-up a few years ago in a 510, and it would run in the low 14s. No turbo - No Nox.

One of the tricks to the L18, is to find a set of L16 rods (3mm longer), and have someone machine the L18 pistons 3mm shorter. This not only gives you flat-top pistons, but also a much better rod/stroke ratio.

I actual have a set of L14 rods out of Japan that are longer yet (137mm). They match up with a custom set of ROSS pistons that I found on eBay (there actually is good stuff on eBay, not just Taiwan tail lights).

But if you are dead set on having a twin cam engine, go with the CA18.I does not have the stupid rocker arm set-up that plagues the SR.

A complete front clip w/ 5-speed, ECU $ wiring will set you back about $1500.

I have an article on dropping the whole IRS out of a 510 into the 620, and I may have to do it if I can not find an LSD for the trucks solid axle soon.

I located a set of ADDCO sway bars thru Summit Racing, and considering (if I find the damn LSD) doing a 4-link rear suspension with coil overs.
