work to fit a big bore throttle housing on 850 T5

[gotmeaT-5]

What work is necessary to fit a big bore throttle housing on my 850 T5, or is it a straight swap, and Is porting the manifold necessary to match the diameter of the housing ? Most importantly where can I get a big bore throttle housing in the UK ? Found one in the USA but import tax will be a killer

Tim Williams on here does a modded one.

Or you could get one off a 960 they are bigger. Pedro has done sumthing like that on BT

as said i'm using one off a Volvo 960 (3litre V6). The bolt pattern is the same but you do need to bore out the manifold a bit, that only takes 5minutes with a flap sander. The 4 wires for the throttle position switch need extending as the switch is turned 90degrees, & obviously you'll need a bigger diameter pipe to go on the end as its quite a bit bigger

i changed to the 3"RIP kit at the same time (already had Volvo RIP) & yeh it transformed the car. When i first fitted the 19t it was that laggy i was thinking of going back to the 15g, but after the TB & RIP it spools just as quick (if not quicker) than the 15g. I did get the dremmel on the 960 throttle body as well before i fitted it (removed the internal ridge & smoothed out the butterfly)

Or just get a NA manifold and TB which will fit and be bigger (the TB that is). You will need to add some ports to the manifold to make it match the Turbo unit.

Good one off to find a NA manifold
