Im Thinking about buying an itr intake maninfold but im not sure if im gonna get any gains in anyway from throwin this on my gsr... what do you guys think? and does anyone know the inlet size of a itr intake manifold? cause i had plans on boring out a tb to 64-68 mm

 

why would you buy a itr manifold, the bolts dont line up you have to modified intake mani for your gsr head, buy a skunk2 or blox intake for your gsr

Like stated before, this will not fit a P72 (94-01 GSR) head. You would happen to have a 92-93 GSR? If that is the case, it will fit, since the ITR and B17 share the PR3 head.

 

Go with the skunk2.

First of all as everyone has already mentioned, the ITR intake manifold is flanged for a PR3 head and does not fit the bolt pattern of the P72 GSR head. The only case where this is not true is with the 92-93 DA version of the GSR with the B17 which does utilize a PR3 head.

As for the throttle body, what are you hoping to gain? Most people think that swapping to a larger throttle body or boring over the stock TB will yield power gians; however, very few people actually see substantial gain. A typical NA engine can only pull in X amount of air; therefore, allowing more in is not going to help at all because the engine is already at its peak VE. The only thing you may notice is an increase in throttle response, but changing the throttle rotor will have the same effect. This is due to the increased Cross Sectional Area of the larger throttle body. You will be allowing more air into the intake manifold with less throttle, but at WOT, your engine wont take any more in as per the reasons stated above.

 

so you recommend that i stick with the stock TB and an aftermarket IM for the gsr?

everyone is really nice around here too by the way...

Not a bad idea...and if you ARE going to upgrade, doing the intake manifold alone is more than enough. I would actually suggest a new set of cams if anything. That'd be in the same price range, but give you a little more bang for your buck.

^^ Do you care to give some kind of reasoning to that post?? I really dislike when people suggest things for no reason....

 

Because he asked what kind of IM to get and skunk2 makes a great manifold for a good price. He asked and that was my opinion. The manifold would be a good choice if he were to make other mods.

 

how much gain would you actually get from a skunk2 IM? i have type r cams and an AEM intake and a few other little goodies and the last thing for me to really upgrade is my IM how much will i gain?

 

Without any kind of tuning, you'd be lucky to pick up 5whp....realistically

 

Ok so thisis my plan... I have a no name intake now and plan on gettin a decent short ram for now. do the skunk2 IM and TB, I like my greddy headers so ill stick with those. but I kinda want to save up and go turbo eventually... so i don't wanna go crazy and start doin a bunch a all motor stuff.
