I have a 92 hatchback with a 99 gs-r motor, it has a custom milled b16 head, type r pistons and rings, ctr intake cam, itr exhaust cam, cam gears, comptech sport intake, 2.5 inch custom exhaust, and dc 4-2-1 ceramic header. I plan on adding an icebox and itr intake manifold. My question is that I have heard an itr intake manifold is not worth using unless you rev 8k or over. Is this tru or not? Would the skunk2 intake manifold work better? Also, do I need to change the manifold gasket when I install the IM?

 

skunk2 IM and ITR IM is identical. Skunk2 basically copied the design of ITR's IM.

 

yea, thats what i thought. Anyways, is that tru about the itr manifold?

 

it doesn't start until 7krpm+

 

yea, so prob. right when the vtec starts to kick in. New gasket and throttle body necessesary or what?

 

i have heard that the skunk2 is alot better, that is what i am ordering!!!!!!!

 

definitely the im gasket will need to be replaced. it'd be hard not to, since it gets caked on the head over time. throttle body is highly recommended to take advantage of the larger intake plenum inlet diameter. it's a great mod in my opinion.

 

alright thanks, I should be ordering one soon.

 

pointless to get the ITR/Skunk2 IM without upgrading ur TB.

 

forgot to mention, if you have the resources, you may want to look into the hondata im gasket. i found out about it after i installed my im. but it looks to be an interesting piece. just passing along some info i never had.

 

what do you mean have the resources? So...........would this ITR manifold come with everything I need if I bought it with the TB gasket http://www.inlinefour.com/typinman.html?

 

looks like they're just selling the im alone. you'll need to buy the gaskets separately. resources=money.

 

no, if you click on the box it says TB gasket...........is that what I want or not? Yea, I may buy the hondata gasket.........looks good to me.

 

oh, yeah. you're right. but that's for the throttle body to im mating. if you take off the tb, then it's always a good measure to replace the gasket anyways. the im to head gasket isn't included. that's where the hondata suggestion comes in. good luck.

 

so, I should buy the itr manifold with the tb gasket and the hondata gasket, would I have to buy new gaskets if I bought a skunk2 intake manifold as well?
