Doesn´t have to cost a lot, just throw some nice GTiR ITBs



Cheers,

Master Sentra how did those work out for you? Is it a 54C head aswell?

Nope, 53J head....

Since the ITBs were installed from the beginning I never had the chance to make a dyno comparison between the stock admission and the ITBs, but never had a problem with them. From comparing my car with others with similar mods I noticed that throttle response was improved but that’s it.

To install the GTiR ITBs on a 53J head, you’ll have to drill some additional holes in the ITBs flange to make it fit plus some minor port matching and of course a stand alone ecu to work with a map sensor.

One thing from the ITBs that you wont get from anything else is the bbbrrrrrooooooaaammmmm!!!!!

Cheers,

dr g you running matrin bruwer ITBs?

Yeah that's the ones.

I'm busy braking in the motor at the moment. Today I set the rpm limit to 5krpm, and forgot the vvl activation was set at 4500rpm.

Man the sound of the ITB's when the cams switch is something else!

Was quite a nice surprise

with crazy high compression, race fuel and i believe carburators bisi made 400hp.

he knows how to build those sohc, by no means is it a street motor, its a full blown, balls to the wall drag strip motor.

stratton.

If you are carrying everything over from the head up, i would run what you said, but i would go manley rods over the eagles, and i would knife edge the 8cw and probably run a crank scraper

still one tough as build!

do you have a panel filter to cover them or are they unfiltered??

I have to hear this beast! Is it broken in yet?

dr g any vids yet?
