HELP is my engine really a B16b?!


id make sure its a b16b block to as i bought one that all looked good and was stamped on the block as b16b but it was a b16a1 restamped. easyest way to check is cheak how long the block is or take the head off and see what it says on the pistons.
Honda Civic Type R (EK9) : Cars : Is it a boat?

that link tells you all about the differences between the b16a and b16b
 
also iirc type r cams have one or two grooves machined into them on one end not sure which. last time i picked up an engine like you did the guy had the valve cover removed so i could double check the valve springs etc. as for the cam cover issue, its not unheard of for people to put a vti one on and keep the red type r one for themselves

yeah that right pateras, although thats not an garauntee that they are type r ones as i remember a scam about people getting b16a2 cams machined to look like type r ones
 
I personally should not be dismantling the engine. So I can't really check anything.

And I cant see whether or not it had dual springs, its tough.

I am trying to figure it out ASAP thogh. Like by today or tomorrow because I am meeting up with him soon.

i don`t think that someone would go into all the trouble if they were going to sell the whole engine. If it weren`t for the different fuel rail along but just the intake mani, i`d guess he sold on the original mani and replace it with that of a vti. But by the look of things, chances are they`ve changed the head.
@ehmis better find out if that`s a gsr tranny indeed while it`s early.

ek9 cams go for about £250 in the uk and the machining would only cost about £20 to get the cams done with the grooves. i'd get the micrometer out and check the lobes etc for the correct measurements
 
The head is a B16a = PR3-1
The Intake mani is B16a.

looks like you've got a frankenstein 16b bottom + 16a head.

Type R head is PR3-3
Type R intake mani is different and bigger

Better get a refund and dont waste your time if I were you. Goodluck

That's what I originally thought, but I've read that the PR3-3 and PR3-1 stamps were just casting stamps?!

I read on HondaTech that the PR3-1 just means it's OBD1 and PR3-3 just means it was cast between 96-00???

I'm not sure whether this is right, but this is what seems to be accepted on HT:

PR3 is the head ID #. The folowing number, either 1 - 4, is from what casting it came from. I've seen ITR heads have every number, 1 - 4, and many different b16 years have different #'s following the ID #...example, my b17a head was PR3-2, my '92 JDM Xsi B16 head is PR3-1, my '00 JDM ITR head is PR3-4, my '97 USDM ITR head is PR3-1.

...There is no way to tell from the ID # and casting # which model/year/make the head came from. The only sure fire way to determine if the head is actually an ITR head is the green paint behind the distributor, which is the paint they slab on there in the factory when they select the best looking ones to go out for machining, and the minor portwork on the intake ports, and larger intake valves.

PR3-1: B16a, B17a, B16b, ITR
PR3-2: B16a, B17a, B16b, ITR
PR3-3: B16a, B17a, B16b, ITR
PR3-4: B16a, B17a, B16b, ITR

How do I know if its a 2001 Integra GSR tranny?

Is it reasonably easy for me to look at the cams?

I have yet to find out if one of the internal parts are b16b or not
 
The B16B tranny should have 'LSD' printed on it in black, and should be printed S4C.

To check the cams, you are going to have to remove the cam rails running across the top....I'm not exactly sure what else is involved or how difficult it is to do?

All B16Bs are PR3-3 doesnt matter what year. B18C would have a different number between 96, 98 and 00spec. But B16B always PR3-3 as theres only 1 spec EK9.

The B16a head is different from 16B and 18C.

You can also tell when you unbolt the intake manifold and take a glimpse of the intake valves. Type R valves have a smooth 'S' curve shape compared to the 16a straight cuts.

When I installed my hondata IM heat gasket, I could define the valves just by looking at it.

B16B is also stamped S4C. Not too sure if EK4 ever came with LSD?
 
UPDATE

I have found dual valve springs on the exhaust side. So it should be in fact a B16B for sure then?

I can get a good look at the springs on the intake side though. Sure its the exhaust side that can be dual or single spring?

Yeh I know the heads are different :nice:

I just thought I would put up the info I had read!

I said it was stamped S4C already :p

And yep EK4 did come with an LSD option on the Y21 box, jdm EK4 SiR's have the LSD as standard I think!
