more or less... Not exactly a type R, but close enough.iNOhc said:so if what you're saying is confirmed.. that mean's i'd have a type r motor by swaping the head of my GSR with an 2000 Si b16?

you would also need the all the intenals, pisons, cams, rods, crank, valve train, all that sorta stuff. I dont know if any of it is the same, im not that familiar with it.iNOhc said:so if what you're saying is confirmed.. that mean's i'd have a type r motor by swaping the head of my GSR with an 2000 Si b16?
but the gsr bare block and the b16 bare head are the same. its the parts inside that are different.

8urcivic did, i wonder if he has any reasoning to back that up with, or if he just wanted to be differentDC2Integ said:BTW who the hell voted for the B16 ?

All b series parts are interchangeablek624ash said:you would also need the all the intenals, pisons, cams, rods, crank, valve train, all that sorta stuff. I dont know if any of it is the same, im not that familiar with it.

right, i just didnt know if the type r has any of the same parts as they gsr or b16, like maybe you wouldnt have to replace all the parts in the b16 head to make it a true type r head.Kuchtaboy said:All b series parts are interchangeable
but if you were to replace those parts anyway, you could get better ones than the type r

Type R specs:
Block: The block is almost identical as the B18C1 block. It shares many of the same qualities, but with a bit more bracing. On the inside are different pistons that yeild a higher compression ratio. The rods are lighter, and the crank is heavier. The crank is heavier to make it more stable under high load and high RPM conditions. On the outside is a different clutch and flywheel.
Head: The head is an exact casting of the B16 head. This is (rumored) to be because Honda made too many of the B16 heads, and decided to use that. Whatever the reasoning, both heads are stamped PR3. But this is where the similarities end. The ITR head is hand ported and polished, and has lighter valves to put less strain on the upgraded valvesprings that come in it. It also has larger lift cams, as many of you know. The ITR head also has a better intake manifold and a larger throttle body.
While the B16 and ITR heads do share the same castings, slapping a B16 head on a GSR block will not get you any horsepower. As I already stated, this would simply move the powerband up, due to the single stage intake manifold, versus the GSR's dual stage. You would also need to bump the compression a bit- be it pistons, head milling, or a thinner head gasket. The returns are not worth the $500 investment. Your money would be better spent on a Rage 4-2-1 Tri-Y header. A true poormans Type-R would be a ported B16 head on a B18C1 block, with all ITR internals.

Even putting it into a G2 is a waste. G2's are only 100lbs lighter than G3's.
Ominous G2

This is what I would do, buy the B16.
Save your money and do the turbo. Then wait for some dumbass to do an LS/Vtec, most of the time those blocks end up in a dumpster. Main reason I hate LS/Vtec. Then you will have a B18C with a B16 head, basically a ITR engine. Build that B18C block drop it in. So you will still enjoy your turbo, the whole time. Best part is, when the boost bug gets you. Your build bottom will be ready to handle it, just dont forget the head studs.

Then why would Honda put them in the G2's in the first place ?Sirfallsalot243 said:Even putting it into a G2 is a waste. G2's are only 100lbs lighter than G3's.
