just out of interest, what sort of HP difference will an extra 3mm clearance give?

-- Standard 60mm gives = 2827mm^2 of surface area.
-- Bored out to 63mm gives = 3118.2mm^2 of surface area.

It doesn't look like much but the gains are there. Without an adjustable computer your gains will be approx 4-6hp. with computer approx 6-8hp.

hi blk-jet

with these bore out are you replacing the butterfly

and do you need to mill the intake also

thanks

yes, a new brass butterfly will be fitted to the original shaft, and the diameter of the shaft itself will be sanded down.

Everything else is original w.r.t. the T.B.

As for the intake plenum, this too will need minor grinding to increase it to 63mm.

everyone do a dyno run before the mod and see the results.

Good idea! That's something I should have done before I started doing all my mods!

Would you need some sort of aftermarket computer to prevent Flat Spots?

Sorry it’s just that I don’t know much about this kinda thing.

Where about in Melbourne are you?

Cheers

You don't need a computer for this mod. The ecu can update the fuel supply for the increase in air.

having a computer siply means you can increase the fuel in more depth and get that extra poofteenth of a kw out.

I'm in Bulleen, about 5 mins from shoppingtown doncaster. I've had mine done already so you can come down and have a look at the quality etc.

I'm also performing this on a 200s and r34 gts-t, so i'll post up the results of all of em so you guys know what your buying!

If only my digicam was working :(
