how to tell the year of your SR???

[blackbeltclub99]

I have a S13 blacktop in my car and the guy I got it from said it was a 98. I do believe him I just wondered is there a date stamped on the engine anywhere? I know on Honda's they stamp the head and block it is in the mold so you can always know what year your honda stuff is. Does Nissan do this to? If so where do I look? thanks for all your help....

Generaly speaking, No you cant identify the year of your motor. It is really only possible to identify a range of years.

If the motor has a red valvecover its a 1991 - 1993.If the motor hasa black valvecover is between 1994 - 1998.

Motors made between 1996 - 1998 are often refered to as the "type -x" motor. They need the J7 ECU.

Thats about the best you are going to get.

cyber is right. i'm in the same situation. You can tell by the wiring harness pin out but it will take quite a bit of research.

Within the 1991-1993 years, you can narrow down the year by looking for heat-sink fins on the head.

Don't quote me on this, but I believe that within 91-93, only the 93 had the heatsink fins.

that would make sense, the ridges are present on all of the later models.

90.5-92 1st gen redtops (NO HEATSYNC CAM FINS)93-94 2nd gen redtops (heatsync cam fins)95-99 3rd gen blacktops (heatsync cam fins)

DJ,this is cool but how do you differentiate an early s13 blacktop from a later s13 blacktop. There are differences but no easy way to distinguish without the ecu.

[Altiman94]

couldnt you check the vin on the block with the manufacturer to see when it was built? Im sure thats all recorded somewhere

[blackbeltclub99]

Altiman94---great idea...where is it located? and would my local dealer be able to tell me anything about a VIN fron Japan?

There is not a vin on the block. i found some #s on the block but no vin #s.

[Altiman94]

just an idea. Check those numbers with nissan

[240dreams]

make sure ur not lookin at the "1998" cc's from the jdm vin plate.

Yup, Hes RIGHT!!

SHooot, I thought they used J7 ECU for all blacktops until I found out the hard way by wiring the SAFC to the wrong Pinouts!!!

I guess my black top is either 94 or 95

[SpeedRacer1]

I am pretty sure its just a J4 ecu not a J7. I have seen plenty of J4 ECU's, does anybody have a pic of a J7?

[nismostate]

what are heatsync cam fins?

[SpeedRacer1]

[ryOs13]

Realized the Blacktop ECU is E5:)

[SpeedRacer1]

62 and 63 are 1991-1993 S13 Redtop SR20DET ECU'sE5 and E6 are 1994-1996 S13 Blacktop SR20DET ECU'sJ7 is a 1997-1998 S13 Blacktop SR20DET ECU

[blackbeltclub99]

Are these interchangable? I mean are all the blacktop ones pretty much the same? Are the E5, E6 and J7 all auto's or 5sp's or were there different versions of each? If so anyone know the difference in an auto and manuel ecu? Is it the other numbers?

[180crafter]

Hey speed racer!!

Go any pics of the plugs that control boost. I need to hook up my power FC's boost controller and have no friggen idea where it goes.

E5 is a manual ECU. E6 is an auto ECU. J4 (ITS J4 PEOPLE, NOT J7) is a manual ECU. The difference between auto and manual ECU's is that auto's will have higher idles, say +800 RPM's while moving. (unless you still have an auto TPS). The E5/E6 ECU is not immediately interchangable with the J4 ECU. You have to repin the ECU's. If you used a J4 ECU on a redtop or early model blacktop, it will only fire on the 1st cylinder.

Unfortunately I deleted a pic of exactly that I had about a month ago. If I remember correctly it was one of the unused plugs found on the igniter chip plate. It may have been this plug in the picture, but obviously if the ApexI plug doesnt fit into this one, then its one of the other plugs nearby.
