Zt 190 vs ZT 160 Turbo performance? - Page 3

TBennet · 5th January 2018, 08:04

I wouldn't suggest buying a 190 on the strength of the engine sound. It's spoiled by the rattle from the inlet manifold.

I bought a 190 a month ago. Excellent condition, 63,000 miles and serviced every year.

I'd read about the issue before buying. It's fairly muted in the cabin, and I didn't realise what it was on the test drive. The harder you rev, the louder it gets, so it doesn't go away either.

You get used to it, but it's a bit of a dissappointment initially when you get the car home, notice the rattle, learn what it is, and that you can't fix it.

Sorry, but the above comment is a bit of a pointless one. It's rather like saying I bought a superb car but the drive was spoiled by the fact it only had three wheels.

The inlet manifold is a simple swap and you can still get rattle free second hand ones. If you wanted you could fit a brand new one. Sort it out and there won't be an issue...

Are they still mapping without afr trace? Quite a few issues of the turbos running too lean at the higher end of the rev range. Mines been ok so far but I wouldn't get mine mapped by them again unless I've got an afr gauge in the car

It may seem pointless to you, but its an honest reflection of my experience and it doesn't seem an unfair comment in response to the OP's wish to buy a V6 for the sake of the sound.

If you can tell me where I can source a new one, I'd be grateful to know. All the suppliers I could find online were out of stock and every enquiry I made came back with no information on when any might be available.

Buying second hand sounds like a lottery I can't afford to play. I would imagine most of the cars they come from are higher mileage than mine, thus, all things being equal are probably at least as rattly as mine is. I'm reluctant to spend £100+ per time to find out.

Regardless of the different merits (HGF vs rattle, sound vs running costs etc.), in my mind, both are probably 'fast enough' for today's roads if you want to keep your license.

I allow myself the occasional foot to the floor as I join the M25 sometimes but lift off before I go under the gantry cameras...the need for speed is fulfilled and the expense briefly justified. If I wanted a faster estate I would have shelled out for a Focus ST or some form of German car perhaps. If I wanted a cheaper/slower car then I'm spoilt for choice..but few would invoke the joy I feel each time I walk past mine as it sits on the drive. I think all of us in this great club put the sheer joy of ownership above all else and hence the great pains felt when damage or failure occurs

Here's my story! I desperately wanted a zt diesel, i ended up buying a 75, i kept it for a month or so and then i realised i was through with diesel. i had £1000 to spend. at the time i couldn't find a zt 1.8t for less than £1500 so i bought another 75, this time a 1.8t. i was put off the v6 engine as a friend had run v6's and was always complaining about the fuel consumption so i didn't see it as an option. i loved that rover! what a lovely car. i have practically rebuilt it in the time i have had it (cam belt, water pump, radiator, drop links, fan, halo headlights,walnut dash, rear blind, ppd leather seats) etc etc (you might get bored if i keep going!) anyway, my mrs wanted a zt and she wasn;t bothered if it was a 1.8t or a 190. we bought a lovely pbt 190. however, she didn't really like it so i ended up driving it for a year and then the big end failed. no worries, back into my rover! i had had it remapped by kmaps with a ss exhaust. problem! missed the v6 so much i went out and bought another 190!

Needs a little DIY fettling but brand new

I had a 1.8 75 for years and gradually added all the goodies. Best improvement was 17" serpents but I also fitted MG135 cams, VVC inlet manifold, 52mm throttle body and K&N filter. It ran very well and would freely rev to the red and handled great. I bought a ZT 190 last year and what a surprise, the previous owner had removed the 18" wheels which I knew about but didn't realise the larger brakes had gone too along with a working manifold and Xeons. I've sorted the brakes, manifold and leaky steel pipes to the oil cooler but it still doesn't feel 52bhp better than my old 75. As for handling it seems to me the only real difference is you feel every bump in the ZT compared to the high speed sofa. I'll be trying some modified exhaust manifolds and a full stainless exhaust next. It does sound nice though.

So.. From the reliability side of things, which engine is the least trouble/expensive to keep alive?

How much is a cambelt change on the 1.8 t ?

And if these liners go, is it new engine time?

Ravinder · 7th January 2018, 00:42

Both engines are good engines and both have their weaknesses like any other car. On the V6, they’re bad for leaking thermostats and duff VIS motors and rattling manifolds etc. The turbos can suffer from head gasket failure, in most cases the cause is a failing water pump. Coil pack issues etc. Cost wise, not much in it in either. They’re both reliable but like any other car, they need to be looked after and kept on top.

Why would the liners go? You’d have to do some damage to the engine to do that...

As for cost on cambelt on a k series, it’s typically around the 300-350 mark with labour.

Sheraton · 7th January 2018, 00:43

All things considered i'd speculate that the 1.8t is the best of all the engines available in these cars

........V8 included

it has to be the easiest/cheapest to repair and work on - access is great in the 75/ZT engine bay, parts are readily available and reasonably inexpensive - plus it's not a hard engine to figure out for diy home repairs
