So I bought a 2000 civic si with a b18c I check the block and it's stamped p72 the head is pr3 and I can't tell by the intake manifold cause it's after market and the headers as well are after market please help I bought the car for 3700 I hope I didn't get ripped off!!!!

 

You are going to have to take apart something to know for sure. Remove the oil pan and inspect the crankshaft for the Type R markings and remove the intake manifold to look at the runners and valves. Take the cam cap off to identify the camshafts as well. Maybe even look down into the cylinder with a bore scope to inspect the pistons and see if you can see any identifiable markings.

Other than that - I am not sure why you think this should be posted in this section. This is the Engine Management and EMS Tuning section.

 

96-97 JDM ITR's basically use a GSR block (P72) and a B16 head (PR3).

But with better pistons, valve train and headwork. A B16 and ITR head are the same exact casting, but the ITR has better valves and valve train, better cams, and a port and polish.

 

Even with the original b16a2 3700 is a good deal if the car is in decent shape. I'd be happy enough if the car came with a gsr block and b16 head at least over the original torque-less block for that price.

Do as suggested above to confirm.

 

I just check date on the head and it say 95 I thought type r were only made from 96-2001

 

Production year castings are always a year behind. Motor made in 95 for a 96 car.

 

Alright koo

 

JDM ITR Block will have stamp B18C 19xxx JDM GSR B18C 10xxx

 

and if i remember the jdm itr was made in 95 and we got it in 96 in us

jdm/ukdm models are always one year before we get them (most of the time)

theres usually green paint next to distributor housing on the head itself

and dual valvesprings

post a picture of engine bay if you can also

 

The block say b18c 19xxxx

 

Then it's a Type R congrats!!

 

You guys act like people don't pull camshafts or swap heads... there is only one way to truly verify.

 

Then everyone tear down your engines and make sure its real!!! Lol
Only an idiot would downgrade from itr head to b16 and install it on an itr block

 

Very narrow minded you are. OP came in here asking if he got ripped off. I would assume that the seller was shady or gave him some inclination to think he was scammed to make this thread. This type of stuff happens a lot. People pull the high dollar parts and put in cheap/common parts in their place. Then sell the parts for a profit and claim what they are selling is legit. It is a very basic concept really and happens more than you think with all kinds of cars.
