Hi guy's to replace my gsr head with a type R what exactly is needed. i've been told i can use my ditributor, is that true? i know i'll need an itr manifold to go with it but as far as machining and the sort what am i going to need to make it all work perfectly? also anything else i should know about it would be very appreciated. thanks

 

headgasket
adj. cam gears since your timing wil be slightly off.
IM gasket
TB gasket - if needed.

 

could you please explain this? i tried using the search like you said before but i couldn't turn up anything

 

type r head is probably closed chambered and gs-r head is opened chambered i think

 

Call O.J. Simpson- He'll whack off the old head for free.

 

Go to HYBRID.HONDA-PERF.ORG There's a article called GETTING SOME HEAD!!!!
It's a complete swap of a ITR onto a GSR block and it tell's you what you need.

does anyone know why the timing would be off if you replaced the head?

 

How much of an advantage is their to having a ITR head as opposed to a GSR head? Coudn't you just P&P your GSR head to accomplish the same flow/power increase?

I'm considering doing an LS/VTEC since my engine is in pieces right now and I was going to use a GSR head with some P&P work... would it be in my best interest to try to find an ITR head?

 

i think the b16 head is the same as the type r...just that the type r head is a little bit more port and polished so i've heard...and the b16 is a lot cheaper..
that's why alot of ls/vtec's use a b16 head...someone correct me if i'm wrong...

Their is a diference, I forget what it is and how big it is... but the GSR head is better than the Si head .... It's also more expensive though.

 

the main reasons i want to do this, is that with the itr or b16 head which are the same, i'm want the ITR becase of the fact that it comes with the cams and valvetrain from the ITR, the B16 has a little better flow than the B18 and the ITR has a minor P&P and a 3 angle valve job, the ohter advantages are the itr manifold bolting up and the fact that you can raise your compression nicely with that head.

By bolting on that head, you drop your CR from 10:1 to 9.6:1.

 

I know for sure the timing will be off, but I am not 100% sure why. Just be careful and research this carefully.
Your compression ratio will also drop.

 

isn't that a contradiction? unless the head was milled and/or a thinner head gasket was used, i really don't see how swapping an ITR head into a GSR would mess with the timing. i couldn't turn anything up with the search feature

 

i've never heard that the timing would be off, but that something i should definatedly find out about.

 

can u run ITR/CTR cams on a gsr head w/stock valvesprings/retainers??

When ever you remove the timing belt from the sprokets and put on different ones you are supposed to make sure the timing is alligned back at TDC. If the timing is off by even one tooth on the belt then you will be bogging like hell. It hapened to me and its a bitch to have to take off the calve cover and all that to do it again so its better to just do it the right way the first time and set the timing properly.

 

"can u run ITR/CTR cams on a gsr head w/stock valvesprings/retainers?"

Yes but you wouldn't be able to rev any higher safely.

 

it is not a contradiction! read carefully. I said I know it will be off, but I do not remember the reason why. I was also going to swap my GSR head for an ITR head and did my research and that's why I was told. Just be careful! I am only trying to help. If you don't think the timing will be off, then go for it. Either way it can be solved with adj. cam gears like I said. Good luck.

 

the main difference between the b16a head and the itr head is the p/p and valve job.. and of course the cams and valve train.

take a b16a head, p/p it, and do a good 3 angle valve job and add ITR valve train(and cams) and you basically have an ITR head, and probably a bit better than the ITR.
use the ITR IM or Skunk2 IM.. or u could get away with the b16a IM, but ur limiting yourself with that.
