having a little bit of trouble on trying to figure out what to do..maybe you guys cam help me out...

right now i have as setup in my car is

b16 head
gsr block with type r pistons on it

now my question is that i have a good chance on getting a type r block

is it worth getting the type r or staying with what i have now...

i wanna go with the one that will give me more power and what not

any help will be great thanks in adance

The GSR, ITR and CTR use the same block. Honestly, if you have a 94 or 95 GSR block, that's the best. It has an oil cooler, which 96 and up don't have.

i honestly dont know if i have 94 or 95 block as i got the car with the gsr block in it already

theres no point to buy a type r block.

Deetz

As mentioned ITR, CTR and GSR are the exactly the SAME block!! They are all stamped P72

thumper64

If you look at the front of the block, right above the oil pan, on 96 and newer blocks, there will be a green VIN plate. If it's missing, it's a 94 or 95. Or when you change your oil, if there's a silver can thing between the block and oil filter, it's a 94 or 95. It's not worth swapping the blocks out for that, but given the choice, it's a little better.

Just go with the GSR block.

forcefedferio

you basically have a type r block.

you have ITR pistons already...b18c1 uses the same rod/stroke as the b18c5

danielblushtein

I guess I learned something new cool


btw why is this in civic forum? post it in type-r or integra or All motor forum. you might get better responce

danielblushtein

nope itr are stamped p73. I'm not sure about ctr. Yea no moint of getting a itr block. Both are 81mm and if you got p73 pistons then your good to go. I'd rather build the head. port/polish and cams and valve train.

btw I heard if you put a ls you will get higher compression a bit. Not sure thought....help me out on this on guys if so

thumper64

An LS crank will up compression about 1/5 point. The changed geometry is going to affect it more than the compression. And as for the displacement, it's only like 2% difference also.

It's late, I am having issues typing. People need to do more reading on this stuff before asking questions. People aren't going to spoon feed answers for everything. Someone has to do some thinking and figure things out.

I have a question and am new to honda tech i have a b16a2 in school and am looking to rebuild for high rev looking to push high 12s on thae track on a stock block head job valve job main bearings do not what kind rod or pistions to use can some one help me out and guide me

danielblushtein

yea dats true man my bad yo


dude HT is ALL about building and high rev so search. like thumper64 said "People need to do more reading on this stuff before asking questions. People aren't going to spoon feed answers for everything. Someone has to do some thinking and figure things out."

go on all motor and check it out or ask question there

Deetz

Wrong, sorry man, no such thing. BTW, i have owned five B18C5 engines, how about you?

It is the Intake manifold that is stamped P73 from the outside of the engine

95lscivic

He definitely speaks the truth. if you can find a 94 or 95 gsr go for it! You're definitely choosing the right blocks though. Stock block girdle and great rod to stroke ratio ftw.

danielblushtein

I know 100% that the pistons are stamped p73. so instead of the p72 that is stamped on the gsr's, what is stamped on the c5 motors?

Deetz

We are talking about the damn BLOCK!!!! The blocks are stamped P72!!!!

Yes, a Integra Type R has it's own pistons, rods, crank, ect...thats what makes it a type R, but the BLOCK is the SAME....get it???!!

Do i have to out to the garage to take a pic?

Lol, go for it just to prove him wrong. Haha

jmart41791

calm down shakespeare we get the point lol

people should just use google instead of starting these type of threads

raidacaipo

yes.. yes you do deetz.. lol jk.

All you people reading this thread right now. Listen to Deetz. He has more knowledge then everyone who already posted here..

Deetz

LOL, got your attention, didn't I? My job is done

FlewByU352

My JDM ITR block is stamped P72 on the back. I know everything else is stamped P73 but I think Honda just made it easier all together over there both GSR and ITR have B18C and both have P72 so they just make 1 block and change internals, head, and other things... atleast I hope because that means I have a motor to inspect if ITR are stamped P73

civic_r87111

Hey Deetz, r u sure the ITR rods say P73, last ones I seen was still stamped P72, was on a usdm ITR tho.

Deetz

I never said anything about the stamping of the rods on a ITR. I understand they are are stronger, but have not confirmed that.

My earlier posts were regarding the engine block cast and stamping

Here's what i could find on rod stamping

danielblushtein

honda-tech at its best lol

ok ok sheesh calm down here. maybe your right cuz my buddy always said they are stamped p73. then by looking at a b18c5 with a black valve cover and no headers or IM, how can you tell its type-r(without looking at the b18c5 stamp)?


btw I see ppl mentioning b18c. As much as I read b18c is jdm gsr and b18c5 is type-r cuz ppl say that b18c is jdm type-r
