What is the engine code for J-spec si motor

I know the si is B16a2 right

A friend got a J-spec B16 supposeally, but i wnat to check the code to see if he is full of ****

 

I believe that they just say "b16" no A2, A3...

 

jdm motors do not have a number at the end....dude above me is right

 

I would have to say never say never. But generally they only say b16a with nothing else

 

JDM sir comes with the B16A

 

JDM Si-R, Si-R II = B16A

CTR= B16B

They have to include the letters to note different 'model' of engine like with B18 there is A, B, and C with C being the most recently developed engine.

 

This all makes no sense, then how do they distinguish between a itr engine and a gsr engine? both are b18c. And between a 1st gen b16 and a 2nd gen b16? both are b16a.

 

There is no distinction on the block in Japan between 1st and 2nd gen B16A engines, just the distinction between the B16A and the B16B using the letter at the end. Obvisouly 1.8L engines are slightly different when talking about the Type-R and the SiR-G or SiR-II, but as far as I know on the block they still say B18C but the one out the the Type-R is a Spec-R engine.

 

Weird, cause it seems like someone could just put an R valve cover on a jdm gsr engine and sell it as a spec-R b18c

 

Yeah found a pic of one and just says B18C. Here's a link to one on ebay: http://cgi.ebay.com/ebaymotors/ws/eB...category=33615. Besides the valve cover the IM is different and you can look at the tranny is S80 on Spec-R vs. Y80 on Sir-G.

 

so the difference between a b16a2 and a b16a3 is?

 

What's the block stamp on your del sol vtec say (assuming it's stock block)? It's one of the two, and there is no difference just OBD-I versions of the same block if I'm right. Got info from here: http://tech.hybridgarage.com/tech/specs.htm

 

so there is no difference in the b16a2/3?

btw thanks for the links jay-c. very helpful


see, no numbers
jdm itr motor

the difference between the b16a2 and b16a3 is like you said, the version of obd. most b16a2's (99-00 civic si) are obd II, whereas the a3 is obd I. and as far as the "jdm" deal??? as far as i understood, they were the same as ours in the b18c1 and c5 basis. but, if they're not the same, then really the only way to know the difference between a jdm gsr and type-r would be compression testing or dynoing.

 

ok, now that the pictures loaded, there's also other ways you can tell. and i don't think someone is gonna go this far to sell a motor. the transmission has the type-r LSD stamp on it, it's got an itr intake manifold, the itr exhaust manifold is shaped different than the gsr, and the one in the pic is a type-r manifold, the red valve cover, and i don't know if anyone else will be able to see it, but the aluminum a/c bracket/motor mount

 

so the 170 hp B16a is just the JDM B16a not the B16a SIR II? or B16A3? The reason I ask is, aren't other JDM B16a's 160 hp?

 

The 1st gen B16A found in civic/crx Si-R and Integra XSi (I believe) was OBD-0 came with cable tranny (typically Y1) and had 10.2:1 cr. These are referred to as B16A1 (even though as discussed before JDM engines don't use numbers on the block to denote the generation.) The 2nd gen out of 92+ VTi and Si-R II were obviously OBD-I upgraded to hydro tranny (probably a Y2) and upped the cr to 10.4:1 which is where some of the extra hp comes from. These are commonly referrred to as the B16A2/3. Obviously then for the 96+ JDM Civics this block is sometimes referred to as a B16A4, but as stated previously this is not stamped.

 

1st gens and 2nd gens have different factorys than the numbers. plugs, head, intake manifold, TB, tranny, all kinds of ****.. If its really dirty, its a 1st gen, lets put it that way..

 

You can not go buy it being a cable or hydro trans. There are very few of the 92 integras that come with a obd 1 engine but still have cable transmission. The only way to tell the difference is you have to have some one that can visual tell the difference between the engines. The difference in the b18c is the way the intake is. FOr the the b16a's you have to look at the dist to tell what obd it is. It is not the easiest thing to do but that is my job. I work at Japan Direct

 

so which is better? j-spec, or us-spec?

 

The good thing about going with jdm is the mileage that they have. The usdm stuff is generally higher mileage. There are people that say the jdm has higher horsepower and on some of the instances that is true.

 

They might sucker a few fools into that but I doubt it. Look at the heads which have the molded P-72 for a B18C (GSR) or P73 for a B18C (ITR). But like most people said JDM blocks use no suffix number so if you are buying just a block without the head then it would be a little harder to distinguish what you are getting.
With the B16A, the first gen has the coolant temp sensor on the back of the block near the oil filter as a 2 prong brass plug-in. The second gen B16A has the coolant temp sensor on the thermostat housing as a regular 2 prong plastic plug. That's the easiest way to tell apart the bottom end on those.

 

That's only if you believe what the importers say. I have seen quite a few first gen B16A's that were "guaranteed" to have "35K or less." Ok, so now you've got a 10 year old+ motor that has low miles knocking and blowing more blue smoke than my old 88 Civic that has over 200 thousand miles on it???

Hopefully every one could tell the difference between the intake manifolds and then there are casting numbers everywhere

That all changes on what company that you buy from. Like i said earlier I work for Japan Direct. The national average miles that they drive a year is 3-5 thousand. And any where you go in a car you have to pay to park, cause of the many many people that are in the country. The fuel is also like $6.00 a gallon. WE go to Japan to hand pick our front clips, so we know exactly what we are getting. One of the owners of this company is in Japan right now buying product.
