**** can identify which sr20 this is?

http://i157.photobucket.com/albums/t...7/ALIM1784.jpg

its sr20 004602w 65F


This is my first sr and I want to start giving it a tune up so I need to know what model and year range it is.

Also what would be the best plugs for it? I like NGK brand (non turbo)




If I can get an answer with a few confirmations it would be awsome, thanks

Looks like an NA S13 motor.

check if the block is tapped for an oil return line. also see what color is the injector..if red most likely na...if purple prob turbo.

Distributor is kind of a dead giveaway...
External coil, side terminals, high-port intake. S13 SR20DE.

Just use tune-up parts for a 93 Sentra SE-R SR20DE, I recall that cap and rotor fits, and MAYBE the plug wires (though they may be too long).
Just use your basic copper NGK plugs for the SE-R as well.

ok so its an s13

i just wanna know if its red top (91-93) or black (94-98)

and is the injector color the only way to really check? I havent tried yet but I heard there tricky to take out.

and yes it is NA, forgot to mention I knew that

Those terms are not technical. Generally the early turbo motors have the red valve cover and the black top motors are the ones w the vtc gimmick.

I believe the first year for the RWD SR20 was 89 or 90 and they kept making them for awhile because the S13 was so popular overseas. I wanna say until 95... but realize this board is mostly for FWD SR enthusiasts so you really want to listen to somebody other than me on this.

There is no doubt its an NA S13 motor from the early days.

^^ Actually, they made the S13 until crica Dec 98 (in the form of a 180sx)

Still had the same engine but valve cover colors were different (came with both red and black top format) and I am unsure if they ever came with VTC

The redtops were available until 94, at which point they switched to the blacktop variant with a updated (T25 G) turbo

eskimo

or so I looked at the o2 sensor and it is the skinny type. (counting on if this is the stock exhaust that was on it...)

so should I count on this being an:

s13 SR20DE redtop?


Also is there another way to see if it is black or redtop other then checking the injectors?

seishuku

With the NA engines, there are no red top or black top... It's just an S13 SR20DE.
This one is more than likely a 90-93, comes with 259CC injectors (like other SR20DE and KA24DE)

RalliartRsX

^^ That is correct (or better yet, they are all silvertops NA)

eskimo

ok, so now I need to search for tune up parts..

anybody have a list of Cross-compatible parts I can get from autozone/kragen/napa?


I found this list but dont know if parts will match up correctly
http://www.nissanclub.com/forums/sr2...over-list.html

need cap/rotor
plugs/wires
fuel filter(going to use 300zx TT one)
fuel filter

seishuku

Most (plugs, oil filter, cap, rotor) from a 93 Sentra SE-R, with an exception for maybe the plug wires... Which might still work, but they might be a little long.

Plug wires and cap/rotor are things I still haven't found replacements for on my S14 SR20DE, but they're still good and I plan on going to coil packs soon anyway.

eskimo

Help again haha

The distributor cap for sentra se-r was too big....cap and rotor from an NX1600 seems to be the correct one..

does this mean that I need to get a NX1600 oil filter also?(right now I have the se-r one but havent changed oil yet)

they look to be the same size but I dont know about the threading...

seishuku

Hmm, weird. I was told a B13 SR20 cap would fit, though a GA16 does have a similar distributor.

The filter should be ok.
