Garrett 3071r? On Rb20

[pixel8r]

pixel8r, always good to get feedback, but comparing a manual RB20 with a GT30 and an auto RB25 with a GT30...likely to be worlds apart.

yeah true, but its a RB24 so not that far off in displacement...its really just manual vs auto. manual would have better (closer) gearing which is why I mentioned that it drops off boost on mine (ie. to highlight the difference).

The manual would likely still drop off boost a bit on the gearchange (i assume they all do - even stock?) but the gear ratios would be closer together whereas with the auto stagea, the gear ratios are designed differently - 1 is for quick acceleration to get the 1650kg car to move, and the rest are set up for smooth cruising and fuel economy...

very different for a manual - usually gears 1-4 are fairly close and 5th (or final gear) is set up for cruising / fuel economy...

I thought I'd post it up anyway cos you never know who will be reading the thread...
