I bought a honda motor swap book to do some homework. In the back of the book it has all of the engine codes and what not. The b18c is listed as JDM and the b18c1 is listed as USDM. I see on here that people have there engines listed as a JDM b18c1 is this incorrect? Or does the book have the wrong information?

 

the b18c1 is the USDM GSR engine. the b18c i believe is the ITR motor in JAPAN (not to sure, someone verify this)

hmm, not too sure, if i remember correctly, USDM is b18c1, JDM is b18c and so is the ITR.. but of course performance of the engine is different.. dont quote me on this and i probably will stand corrected.. and of course, USDM ITR - b18c5

 

Im not sure if the b18c is ITR or not, but it is def. JDM

where'd you get that book?

 

the b18c is also a jdm gsr

 

According to Spoon Sport's Tatsuru Ichishima, The B18C stamps means it could be a C2 or C3. C1 through C3 of the VTEC B Series are considered the knock-down models in Japan. The favored engines are the B18C4s, which are not available in the US. This was out the 2002 August issue of Import Tuner that I have.

 

i have a obd1 jdm gsr (sir) motor and it is stamped with b18c. I'm pretty sure that they are identical except jdm version has a little higher compression and doesn't have evap. stuff on it.

 

So my question is when people say they have a JDM b18c1, they really dont because it doesn't exist?<TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD>Quote, originally posted by VTEC Genetics &raquo;</TD></TR><TR><TD CLASS="quote">where'd you get that book?</TD></TR></TABLE>

I bought it at Barnes and Nobles. It has some helpful information for the people that havent tackled the project before.

 

thanks.

Thats correct theres no JDM b18C1. The people that say that are just jumping on the JDM bandwagon

 

b18c is JDM only.. but it is not just ITR... it's also sir-g... both are stamped 'b18c'

There is no such thing as a B18C2.

B18C = JDM Integra Si/SiR/SiR-G and JDM ITR (96 and 98spec)
B18C1 = US GSR
B18C3 = Aus/NZ Integra VTi (same as US GSR-Dual Runner IM)
B18C4 = UK Civic VTi

The B18C4 is the same engine as the US GSR (dual runner inlet manifold) and JDM Si/SiR but it has lower compression than the JDM Si. The B18C4 has 10:1 CR as opposed to 10:6:1 of the JDM Si/SiR

to verify you have to check the casting on the head.
p72=GSR
pr3=rRRrrRRRRRR

 

I won't argue if there is or isn't a C2, but that's what was printed in that issue. So if there isn't a C2, then it looks like Import Tuner misprinted the interview with Mr. Tatsuru Ichishima. But thanks for the correction.
