Thumbs up

Okay . . . B-Boogie is absolutely on point . . .

DVS . . . my reply was to thaa not to you . . . stop bein' touchy . . .

I haven't found specifics on the internals of the engines . . . but here's something to read in the meantime:


The SR engine range:

-4 cylinder inline

-DOHC

-4 valves per cylinder

-Chain driven camshafts

-2000cc and 2000cc intercooled turbo

-ECCS engine management

Used in :

Almera GTI
Primera P10
Primera P11
Primera P11 144 series
Serena
200sx
Sunny N14

This engine first appeared in the Primera in 1990.
There have been several variants, depending on the fuel system.


-SR20Di Single Point Injection, used in early Primeras.
-SR20DE Multi Point Injection, used in Primera GT's, Sunny GT's and Almera GTI's.
-SR20De Multi Point Injection, used in ordinary Primeras and Serenas
-SR20DET Multi Point Injection with Turbocharger, used in 200sx and Sunny GTI-R

In addition, the injection system on early Primera GT's is totally different to later models, but both are classed as SR20DE.

I'll be back with more . . .

I suggest we just wait for thaa to tell what the Nissan dealer has to say. Oh, and I already emailed the guy who runs the Nissan Information centre - it's not a good idea to start spamming his mailbox

OK. Here goes: the guy who runs the "Nissan Information Centre" website emailed me back and I quote: "Cams are different. Other major changes were manifolds." (obviously, together with the fuel feed system).

It is my understanding that the SR20De is the throttle body injected car. Let me check my Nismo (Japan) catalog to see what I can find out (I can't read kanji) and my Hyper Rev Primera book.

noooope...

lower case "i" stands for throttle body in Nissan engine codes... so if it was SR20Di ...then it would be throttle body

Welp, I was wrong. The Di is indeed the TB injected version. I could not find anything in either of my references on the De. I know it exists, but it apparently wasn't sold in Japan in a Primera.

Re: SR20De vs SR20DE

In Europe:

SR20Di 116ps - (1990-1993) TBI, intake cam set for more torque at lower RPM
SR20DE - MultiPoint fuel injection, comes in two versions:
High-port 143 ps (1990-1995)
Low-port 150ps (1996-)
the difference being that the high-port has a stronger lower end of the engine and the throttle body is beneath the injectors, whereas the low-port version has its throttle body above the injectors.

SR20De 125 ps (1993-1996)/130 ps (1996-) - different from SR20DE at the cams, ECU and exhaust manifold. (all slightly less aggressive)

I hope this explains it...
