really like the zs thinkin of getting one.

main question is are they better cars eg quicker more tuneable more economicale bla bla

well I have a 620ti, my brother has a ZS v6. Never had a side by side race, but I've driven his car and I'de have the ti any day!

Yes wiht the v6 there's no lag, but that's just kind of like the fore play before the turbo kicks in

Certainly much more exciting to drive and you get a bigger sence of power.

But the ZS definatly wins in the looks department.

Just out of interest, I have had a go at a ZT v6 and the bloke was amazed, I had him off the line, he over took at the top of 2nd but I caught up and passed him in the end, I did however hit the rev limiter in 5th.

He actually followed me into the petrol station to ask "what the hell have you done to that?" - I don't think he was expecting to be beat by a grandad mobile, wich made it all the more fun.

lol yes thats my fav thing bout owning a ti

yes mate a grandads car just nailed you lovin

so hows about on the tunning side of it many zs's been tunned on here

The ZS wont be as tunable as the Ti. Turbo cars are much easier to get power from, up the boost, FMIC, bigger turbos, more gains from exhaust mods etc etc.

I'd say the advantages of each car are:

Ti: Power, tunability, off boost economy, massive torque and feeling of speed

ZS: Looks, handling, brakes, sound of the V6, smoothness, no lag

In a straight line I'd bet the Ti would win a race. I'd wager than with std cars the ZS would thrash the hell out of the Ti on a road with corners though.

ah yes, forgot about the handling, must admit it's probably the thing i hat emost about my ti, it is defiantly barge like

and having driven the ZS it's definatly better but could still be inproved. I have driven similar sized cars that are certanly better.

Ti is a fair bit faster to be honest, my old Ti was faster than my 200 with the KV6 fitted, and mine is more powerful than a ZS, and in a lighter car.

Tuning on a KV6 is expensive to say the least, if you want to change cams, there is 4 of them, manifolds 2 of them etc.

Ti is probably just slightly more economical expect about 28 to 30mpg from the V6, probably just slightly more on the Ti, it depends on what sort of journeys you do.

hmmm, interesting. I'll have to have a head to head with my bro's ZS. I can certanly see it winning on the track, but I'm pretty sure my Ti would win in a straight line.

I'll let you know the out come...

So you launched harder and he made back the ground and passed yu by 50mph and it took you till 150mph to catch him up? Sounds like a loser-flyby!

ZT is also a "grandad" car...

i have a zs 180 and a turbo coupe, although the book figures are different on the ti to the coupe, i still don't think the zs would keep up with a ti in a straight line, i'm sure it would handle better though, the KV6 seems a smootheracceleration and the T16 is a savage acceleration , a lot more torquey, as for fuel economy the ZS is a lot better than the coupe

600ti has an LSD whereas the ZS doesnt, a HUGE factor beiung overlooked here.

gav2pac · Post by **gav2pac** » Tue Feb 27, 2007 12:31 pm

i think it would be close, and also a lot depends on the driver

Scott · Post by **Scott** » Tue Feb 27, 2007 12:45 pm

ost zs180's will be making 180 all the time, the same cannot be said for most Ti's?

I didnt even notice that much of a difference when i took the bleed valve off, but running actuator boost only made 173bhp @ 6psi , so id expect it to be comparable to zs180? With a Ti running how it should, i think it would beat a 180 off the line and straight line?

Nah like I said he followed my into the pertol station for a chat, he genuinly was amazed, we'de been launcing it from the last few sets of lights, when I said he caught back up I mean he managed to get a couple of feet infront for a few seconds as I ran out of steam in 2nd.

that is one of my gripes about the ZS, the coupe with the torsen pulls me in to the corners whereas the ZS wobbles and twitches if you get too confident with it.

Hmmm anyone read that thread??

The Pistons on the T-16 Turbos have lower Vickers (hardness) values them on the non-turbo T-16, changing them around could see reliable power on the turbo above 280bhp. My brothers Ti has been running at 250 bhp for over 4 years and has yet to fail in any way which is good considering the way which it is driven and has covered ten times my mileage!!

Sounds like utter trollop to me.

peteT16 · Post by **peteT16** » Sun Mar 04, 2007 2:27 am

imo the info about turbo pistons having a lower Vickers hardness value may well be red herring, they were probably designed that way because of the greater temp range in a turbo engine, nasp pistons may be harder, which would also make them more brittle.
