what is the difference between the type r head and the b16a head... i just wanna know is there anything you can do to make the b16a redline like the type r? thanx

 

If its a stock motor and you arent making any power at that RPM range, why would you want to rev that high? I mean, you could rev that high just by chipping the ECU, but there is really no point unless its built/tuned for it.

 

yea all u have to do is chip ur ecu.


the dif between the heads are the cams are a lot more aggressive on the type r. you could get type r cams in your b16 head and youll feel a gain. but remember higher rpm doesnt mean more horsepower, and u could blow your b16 :-)

 

the cast is the same. the itr head has a mild port, more aggressive cams, and different valvetrain that can handle the higher revs.

 

my buddy has a fully built all motor B18c with a B16a head with hondata s300. he can take his motor all the way to 12500 rpm's, but there is no point in taking your car that high, your powerband will be cut of at a certain point and your than likely going to blow or completely damage your engine.

Only other difference I can think of is the LMAs (lost motion assemblies) are stronger/stiffer on the ITR head too. They have a different part number all their own for the ITR/CTR engine as opposed to the B16A/GS-R style ones.

i wouldnt say different valve train but it has dual inner and outer springs on both the intake and exhaust sides of the head not just one side like the b16 has. advantage is that u can run a slightly larger cam profile without damage and can go a lil higher on the revs. personally the itr valvetrain is a good upgrade for stock parts such as itr cams but if ur going aftermarket theres no point because ur going to need different springs and retainers.

the port job isnt really even a port job. all honda did was smooth out the cast in the bowls and ports so the air flows with a lil less turbulance.

thats about it. aside from different lma's.

 

get a bike if you want to rev at 18k

You can use type r cams and valvetrain but upgrade to titanium retainers, they are the weakest linking for type r. My friend dropped a valve and destroyed the motor!!

Actually Ti retainers are a WEAR ITEM and are intended for RACE engines.

Everyone reads "ooh titanium retainers!" on the engine mods listed on every built car in every tuner magazine and thinks they're the best for a daily driven engine.

Your friend had shitty luck when he dropped a valve - ti-retainers wouldn't have made any difference at all in that. Ti retainers are lighter - that's it.

I've got about 75K on my B18C5 with frequent revving to 8400rpm or so pretty much any time I drive it and it's never let me down on the 1005 bone stock internals.

 

I use to think that it would be cool to be able to rev up to 8k but it would actually hurt your car if your engine was not built to rev that high.
