Throttle body intake size?

mantianak · 18th March 2007, 22:12

To save me doing the minor task of looking does anybody know the size of the air intake body on the KV6?

I've got a breather separate to an induction kit but it's very loud! I was looking at something like this...

A tube could supply air to the breather and should reduce the noise. But I want to know the step-up/down size before I buy.

Are we talking about the size of the throttle body itself or for the breather tube on top of said throttle body?

The big air intake bitty where the air filter attaches to the metal body, not the rubber bit or the breather on top. From memory I think it's about 70mm diameter. Not sure tho.

70mm does sound about right from what I recall too... Don't quote me on it just yet though, I'm still checking various sources for confirmation....

After much searching the conclusion seems to be this:

70mm throttle body on the ZT160 and Rover 75 (2.5KV6, not sure about the 2.0KV6)

80mm throttle body exlcusive to the ZT190.

If anyone knows any different then I do, of course, oblidge accordingly.

Great stuff.
I'm now thinking of finding a Y-pipe to have 2 filters fitted. There's enough room... just.

Problem is I can't seem to find the right shape of pipe. I'm thinking of adapting a Mitsubishi GTO intake pipe, although I'm having difficultly finding out the sizes of the pipe. No point in using it if their too thin.

Not sure of the throttlebody size, but the hose on my 190 has an ID of 73mm, apparently the Zs180 has a 70mm ID.......
Its causing a nuisance as I try and fit my K&N!! (you can't get a 73-70mm reducer)

We'll I'm told (and I've always repeated it) that TC is a bit too keen and for the 190 it can snatch away power when you don't want it to so it can be more of a hindrance than a help, I've read a few times that owners of the 190 say that so it must be available,
The only reason I'm after it is because I'm planning on a jolly in my 190 to Norway up to the arctic circle and I want every bit of help driving, and that's abs (which the car already has, TC, proper Nordic winter tyres, tyre chains and maybe a bit of skidpan practice 😁

Agree that TC can be a hindrance when you want to power your way out of a skid. ABS - simple, don't touch the brakes if the car isn't in a straight line.
Time of year for your visit? If in winter then a big yes to winter tyres, TC is over-rated and nothing I can’t compensate for, and skid-pans are fun and part of the driving test in Sweden but unrealistic with the possibly exception for bubble-freezing rain. If you have anywhere with loose gravel nearby take the car for a spin and see how the car responds, far more useful than TC. Not much you can do with a front wheel drive car to compensate anyway.

Regards

I've only ever once driven the ZT in snow. And it was not a pleasant experience to the point that I gave up on my journey before I'd even left town . Admittedly I didn't have winter tyres , but I felt the 18 inch wheels and all that power though just front wheel drive made it unpleasant even just on the flat.

I might have been spoiled with the old quattro though!
