How do you know differentiate between a JDM GSR or a JDM TYPE R motor? Do both read "B18C" on the block?

on the R, the tranny would be stamped with LSD, the valve cover would be red, you can tell on the intake manifolds, obviously different. ummm, the header is different, more tubular and made of SS.

 

I think that t type R is b18c5

umm, b18c5 is USDM i believe...

 

i think JDM ITR is stamped B18C R and SiR-G(there is no JDM GSR SiR-G is the JDM equivalent to GSR) is B18C on the block

 

Both the JDM GSR and ITR have "B18C" stamped on the block.

Look at the head and you can tell if it is and ITR or GSR motor. GSR has a "P72" stamp and ITR has a "PR3" stamp.

i think you meant the ITR has a PR3 head

 

Both are stamped B18C on the block. USUALLY the transmission will have LSD stamped on it for the ITR motor, however LSD was an option on some SIR-G's. The 98 was the first year that had the nice tubular header, 96 and 97's had a slightly different header (I believe it was a 4-2-1). I'm not going to touch the head stampings...I think the ITR is stamped P73...not totally sure though. You can also look at the intake manifold and tell if it's a SIR-G motor or ITR motor. Either way though, both motors are great.

 

bigg teggie is right, thats enough said

 

where the hell do you people get "R" from? its just B18C not B18C R!!

just narrowing it down.....b18c can either be sir g or type R.....so people say b18cr hope you get it

 

that is correct sir

 

all jdm engine do not have numbers are the engine coad gsr's and itrs were both just b18c and all years b16's were just b16a

the visual differance between the gsr and itr motor is that the

itr has a red valve cover and the gsr has a black one
the itr has a single stage im and the gsr im points down which is a dual stage runner
the gsr head is stamped p72 and the itr is pr3
the 98+ itr has the 4-1 header with 2.5 colector

there is no other visual differance from the out side
if you really want to make sure just pull the valve cover and look for rings on the itr cams and paint on the valve springs

 

i've seen alot of itr's with faded green paint on the distributor side of the head...
