Title: What is Good sized Turbo for a Small Bridge Port
Post by: antnicuk on November 22, 2006, 07:13:41 PM
Just wondered what sort of size turbo would be good for a non laggy track use set up with a small bridge port like a half bridge.



Also, how difficult is it too keep the noise down to sensible levels ie 100 dp.???

T04Z must be the favourite for track I would have thought...

i have one of those on my street port at the mo,  it spools quite early so i thought it may be quite small for a bridge,  it has a .96 exhaust housing so i spose i could get a bigger exhaust housing.  1.10 ??

Yes,almost instant spool up on a full bridge,and only little later for half bridge.

What about a smaller a/r GT42 ??? Maybe even the GT35 R500 that one of the yank vendors do.

i like the sound of the gt35 as i have a near new one!  a bigger a/r hot side shouldnt be too difficult to get hold of.

HKS TO4Z is the one for low lag. Blitzboy has the Garrett kit with a larger exhaust housing which is better for a little more top end power afaik.
