RB26 D20423A

I ordered a motor and it is supposed to be R33 RB26DETT. Above is the engine number that i requested from them. Was wondering if anyone can tell me if it really is a 33. Specifically someone who has the FAST software and maybe they could run the number through it and let me know. Any help would be great. Thanks guys.

My engine no is RB26 038604A from a late 93 R32.. Hope this also helps.

wrxhoon - any idea how to decode the numbers without NISSAN FAST software? Do these numbers mean anything?

I don't think you can tell with Nissan fast how old the engine is by the number.

I have a list of engine numbers and the aproximate built date . You are correct in saying your engine was built in the second half of 93.

How sure are you that it is out of a 32? Just wondering cause the company knows i am going to be checking to make sure it is a 33 and they assure me it is from an r33. Also the reason i want a 33 is so that I dont have to deal with the small crank collar on the early 32s but i also heard that later 32s might not have this problem. Is there any truth in any of this? thanks

The updated / larger crank collar was fitted to late model R32's. My engine was recently stripped down (late 93 model) and its obviously got the larger crank collar. Ask the company to take off oil pump and check the collar..

I'm fairly sure but i can't be 100% sure ( according to my records its a 32, second half of 91 actualy).

Have you got a pic of the engine? The engine may be out of a 33 but originaly was in a 32, someone may have fitted it in a 33. Later 32's do have the 33 crank.

I am doing the swap myself so when i get the motor I will be taking off the oil pan anyway since I need to use the rb25 unit. Is it possible to tell visually by just removing the oil pan? either way I will take pictures and post them up on here of the crank collar. Also I was wondering if the engine number I listed is exactly correct. Should the D be a 0? I had some trouble reading the hand writing of the guy who gave it to me.

      Version 1 aluminium airbox is.......not acceptable No pics as I "didn't like the look.....alot" Even after all my "CAD", and measurements, the leg near the fusebox just didn't sit right as it ended up about 10mm long and made the angle of the dangle look wrong, the height was a little short as well, meh, I wasn't that confident that Version 1 was going to be an instant winner I might give Version 2 another go, there's plenty of aluminium at work, but, after having in on and off a few times, and laying in the old OEM airbox without the new pod filter and MAF, there may be an option to modify the OEM air box and still use the Autoexe front cover and filter.... maybe This >  Needs to fit in here, but using the panel, and not the pod, the MAF will need to fit in the airbox though> I'm thinking as the old OEM box and Autoexe cover that is sitting in the shed is just sitting around doing nothing, and they are relatively abundant and cheap to replace if I mess it up and need another, it may well fit with some modifications to how the Autoexe brackets mounts to the rad support, and some dremiling to move it get in there, should give me some more room for activities, as I don't want to move the MAF and affect the tune Sealing the hole it requires to stick it in the air box is simple, a tight fit and some pinch weld will seal it up tight  I am calling this a later problem though

      and it ends up being already priced in as though you're just on 91RON without any ethanol. Car will lose a bit of economy as the short and long term fuel trims bring down the AFR back to stoich or whatever it is for cruise/idle for the engine.

      Oh, you are right. But, in Australia E10 is based on 91RON fuel and ends up being 94RON. Hence it being the cheaper option for economy cars. The more performance oriented cars go for the 98RON fuel that has no ethanol mixed in. The only step up we have left then at some petrol stations is E85.

      There is a warning that "this thread is super old" but they ignore that anyway...

      With 10% Ethanol, we're talking 2-3% fuel consumption difference. The emissions reductions and octane boost in my opinion far outweigh this almost non existent loss.    My tanks sitting at 80%. Luckily that should go down fast as I'm on vacation again for the next two weeks.
