Itr Head

[2000Si]

I know it's not a full blown swap question, but it IS a swap question none the less. Move if necessary.

Brian (BDN on hondaswap) got me to thinking earlier tonight. He told me I should get an ITR head and build it with the GSR cams I just bought, new retainers and springs, and a stronger than stock 2layer gasket (I'd go one layer, but how much does that raise compression? Since I wanna boost, I don't want that). I had actually thought about this before he even brought it up.

Anyway, if I were to entertain this idea... How much would a bone stock, completely bare ITR head run? and would the factory Porting be worth my time? Cause if it's going to cost a shitload I might as well just get a bare plain B16a head and port that.

I found one for sale on Honda-tech for 1400... I really hope that's a built, fully assembled head though...

For those of you who don't know, I'm doing basic bolt ons (i/h/e), GSR cams/gears and a JRSC at 6 psi Until the bottom end can get forged internals.

Suggestions Please.

Hell I want to know where can find bare heads my self. I got full Skunk2 setup but no head sense old on got stolen out of my garage....


I would htink be cheaper to get gsr or b16 and port it....From what I know head stregth is not diff betwenn just porting and parts

[2000Si]

well yeah, the only reason I'd swap is because the stock porting... but if an ITR head is more expensive than doing a street/strip PnP on my current b16, i'd say fuck that.

A GSR won't work without the GSR IM, and I don't feel like trying to wire for IABs while trying to source a P72.

You can actually make really good power under boost with the ITR cams. I wouldn't bother to switch- but that's me.

nor would I

switch heads you mean? Cause the Cams are mine, and they'll make a bit more power in my b16 until the SC gets installed.

[Calesta]

No, I mean switch the ITR cams out for GSR cams. Keep the ITR cams.

[2000Si]

Oh. I don't even want to pay for ITR cams. I just want a bare head to drop onto my a2. If not I'll just spend the 400 or so to do a mild PnP on a stock a2 head.

my port and polish cost me $70. i'm not sure if that was a good deal or not, but i can't imagine a stock ITR head will flow better than a b16 head with a decent P&P, and it'll probably cost a lot more.

[Calesta]

Whoops. Reading comprehension > me.

A good quality port/polish job will always cost more than $70. For $70, you probably just got a gasket match, if even that.

If the ITR head is going to cost you more than a few hundred bucks, I would recommend sending out a B16 head and having it ported to your application. The factory port/polish job on the ITR head really isn't all that impressive, so paying more for it isn't worth the cash.
