poor mans type r
ive been hearing that if you get a b18c1 block, have it bored to 84mm and get itr internals, use a ported b16 head that it is basically an itr engine. tru? if so, what else is needed to be done? crank, cams ect

While you are at it, throw a Civic Type R intake cam in there, with an ITR exhaust cam with some double springs... That would help as well. When you start to modify air flow it is a good idea to get the ecu chipped use some sort of engine management to "tune" the set up as well. A V-AFC will do the job for mild engine set-ups. So often is engine management overlooked..

Re: (bigblockEG)
Correct me if i am wrong, but i dont think you need to change the head, doesnt the gsr head have just as good of flow as the b16 or is that the type r?

that would be called the "rich idiot's type r"

Heh... if you use ITR pistons, you'll have "zero" compression and lots of "rod knock"

Pretty much, but if you just slap a B16 head to a stock GSR block, you're compression is going to drop to around 9.8:1 so unless you add some higher compression pistons (ITR, SiR, or even PCT/CTR), then it's not really worth doing a poorman's ITR in my opinion.

woow....11.4 cr w/ b18c block+b16head+pr3 pistons (how accurate is this calculator anyway?)

C-speedracing's compression calculator is off, and has always been off. I do the calculation myself and come up with those number so I trust my numbers and forumlas rather than somebody elses. Remember, it's the internet so people can post up anything, and others may believe it, even if it's not accurate. Just a frame of reference..... a stock US GSR compression is 10.2:1 and if you slap on a B16 head to that block, you drop .2-.4 points of compression, depending on the head deck and head gasket, and also due to the larger cc on the B16 head, and if it's ported.

I calculate a stock B16 head, stock GSR block, no milling or decking, stock GSR rods & crank and PR3 SiR1 pistons to come out to 11.61:1 compression. If you use P30 SiR2 pistons, 11.79:1 compression. If you use JDM ITR pistons, 11.13:1 compression.

Correction, according to honda/acura, a stock GSR compression is 10:1, B16 is 10.2:1.
And yes he is right, C-speeds calc is off. I 99.9% of the time trust what facts Newman states, because he knows his ****.
