I am going to build a reliable engine with brand new type R valvetrain on the B16 head, so I pick the ITR Cams for my daily drive build

it will be going with a 84.5mm RS ITR pistons which is a 2.0L w/ Compression Ratio of 11.5:1

Does anyone have a dyno chart of B20 ITR cams that makes more than 210whp..?

 

my buddy did a similar build 84mm rs itr piston, b16 head, ctr cams, and made 209whp so my guess is yes!

 

I made 214/151 on a dynojet with ITR cams on my 2.0L during my 'break-in'.

I could only run a total of 19* timing at peak torque. Was not ideal. If you do not want to upgrade valvetrain, I highly recommend some BC3+, Skunk2 Tuner-1/Blox-A, or Toda A. Something along those lines. It will help improve the margin before knock.

I'll post a graph when I get home tonight.

 

214/151 is a very good number, do you have dyno charts ? Thanks

what kinds of header, intake, and what size TB does that setup use?

I really want a fully built reliable head that would last me at least 60K km....

 

ITR cams are far from ideal for that motor. For the same money, you can get something that will make more power.

 

my noob *** agrees 100%

 

I got a deal on the itr cams and valvetrain..

also my concern is reliability on the valvetrain that would last me a few years..

 

There's lots of good aftermarket valvetrain and cams out there that will last you for years. Myself and many others are good examples of this.

 

I made 211Hp 148Tq on a 85x89 B20Vtec, it's hard to beat OEM reliability. With that said...I'm in the process of upgrading cams.
Dyno plot is on the 1st page of my longevity thread below.

It would be interesting to see some ITR and aftermarket cam, dyno overlays if anyone's got them.

 

Good example that you can make good power with OEM parts, slight modifications and tuning.

 

i built a b20 a few years ago wtih wiseco 2 cc pistons, itr cams, itr intake manifold and custom rmf header. it made 215

so yes you can make over 200hp and you dont need (or really want) high compression.

 

I'm having problems finding the dyno files, so all I have this that graph (uncorrected). I have files for ITR cams vs BC5's, Pro2's, Pro3's, and a custom grind Web cam.

 

Good info, in for the VS plots if you can find them.

 

thanks for the dyno graph
this thread is really informative

but sorry to say it that~ I now bought a set of brian crower stage 3 cams off a guy here
which would push me to 220+whp territory, as far as the valvespring kit.. I think i will just stay it with chromo-steel retainer kit off brian crower for reliability...

sorry to say that I leave the stock scene...
