Hello my name is Bill and I am new to this forum. I have a small dumb question. I own a 96 Sol and I recently purchased a b18c from a local shop and it did not seem to have the typical 4-1 JDM header on it and i've been starting to wonder if this is even a type r motor to begin with. Does the jdm SIR-G have the same intake manifold as the GSR or is it the same as the type r's. I'm actually just trying to figure out if i've been scammed or not. I've tried to get the serial # on the block run through Honda and that was a no go. I've got all the stampings and date codes off the block but am still unable to figure it out. From what I know both models yield the same compression ratios meaning that there would've been a change in the camshaft profile and ECU( I guess). I'm needing help bad. I thank you in advance for any help that may be provided.

 

The b18 from a sir-g has the standard dual runner intake manifold, while a b18c from and integra r has a single runner manifold, similar in design to a b16a manifold if you know what that looks like.

 

Not to be all nooberrific about it but i'll post a pic of the motor and hopefully someone could tell me .

 

Does the sir-g look like the intake manifold off the us spec gsr? CAuse I had a b16a2 in there from the factory and between those two intake manifolds they looked the same.

 

sir-g manifold looks same as gsr.

 

yup, SIR-G has the curvy manifold with the throttle bodie lower just liket he GSR

B18C-R has manifold looks more similar to the b16 curving up with the throttle bodie more visible

 

I truly appreciate all the help and you guys have taken a big load off my shoulders. Thanks again.

 

Well here is a pic of my ride with the questionable motor. Toda header, spoon rods and pistons, skunk2 intake manifold port matched, Skunk2 valvetrain,etc.

 

looks like a type-R engine to me. Type-R intake manifold and all.

Btw, a GSR I/M will not bolt up to a type-R or B16A head.

 

that motor could be GSR, he said he has Skunk 2 intake manifold

 

If it has a skunk2 intake manifold on it that won't help you. The aftermarket skunk 2 for the GSR/sirg is designed like the type r.

If you say you have all the stampings a SirG will have a p72 and a type r will have a p73 stamp on the head

 

Okay at this point I still don't know what kind of motor this is(lol). I know one of the stamps on the head says PR3-2.I could not seem to remember seeing a p73,where would it be located? And before I bought the SKUNK2 manifold it had a manifold like my b16 and when I replaced the pistons they did have a P73 stamp on em. thanx again.

 

Ok I made a mistake, Type r heads are pr3 heads. same as b16 w/ polish. If you have a pr3 head and p73 pistons then that is a type r motor (unless someone did a poorman ITR setup w/ b16 head. ) I'd say it was type r.

 

Yellaboi, I would like to thank you for allowing me to breathe a lil easier. It was a dumb question yet I needed to know for sure. to be able to get answers this fast when your in a pickle. Car should be done real soon, I will post pics. Thnx again.

Well it's definitley NOT a GSR head, because there's no water neck/spout erecting out of the head in front of the VTEC solenoid area. Also, if he looks in the area betwen the VTEC solenoid & distributor he'd have this raised "72" number, which I'm bettting he does NOT have there - He should have a '30' instead, and there should be some green paint near the distributor area too:



I'm betting thats a full blown ITR engine.

The only real way to tell if the block is ITR spec, is by either taking the head off to view the part number on the piston tops or remove the oil pan and slash sheild, & crank the crank till you can see an "R" on the crank as seen here:



As for the head, he can remove the intake manifold and look down into the intake ports to see if they're lightly ported, usually seen as a lighter shade of aluminum. Also remove the valvecover and peep out the valve springs, intake springs should have yellow paint markings on them, exhaust springs should have blue paint markings on 'em.

 

Well thank you for all the info . I went back and pound a pic which i had taken that clearly has the 30 stamped into it. Thanks.

 

good info

 

i have the same dillema with my new b18c purchase...im suspicious to see if the block is gsr or tye r

on the bellhousing under the IM there is a code that says p72, my Q is do both gsr and type r castings use the same code p72 on the block??

do i have to open the oil pan or remove the head to check the pistons or crank to verify whether i have the real type r???

any info is appreciated..thanks

 

anyone....???

 

check the numbers under the "b18c"
if it has 19, 20, or 21 as the first two digits...you got a type R

Does that rule apply to JDM ITR blocks too&gt;?

thats all that applies to...

USDM and UKDM ITR all had something after the C....

 

thanks for the great info, yeah my motor has the number 19 under b18c

that cleared things up....appreciate the info

 

and he has the type-r throttle body if you noticed-and look on the underside of the vavle cover it should say pr3 on the side where the cam gears are at on the first spark plug hole!&gt;

 

is there any difference between the type r and gsr rods? like different stamps on them?
