Hi Guys. I thought i'd post some photos of my 16v somewhere it will liked!






Current Spec.
Nissen Radiator.
57i With alloy heat shield.
Polished and flattened spindled TB.
Some silicone hoses.
A Pair of 10" subs and Component Speakers all round.
It has the rare leather interior.
Bosal Exhaust system.

The Engine is the same as the one in the 306 S16. These cars are getting quite rare now.

Can't remember the last time I saw one of those.

It's a nice looking motor.

Looks well looked after.

ZX's look quite sleek compared to modern hatchbacks and that 16v power/weight is still very good by modern standards smile

I had a 1.9 Volcane many years ago which wafted along nicely. That engine was quite harsh at higher revs though, so the 16v is no doubt much sweeter.

What are the wheels/tyres? The Volcane as above was 195/60*14 and my current everyday steed is a TD on either 175/65*14's or 195/50*15 depending on my mood.

It's rolling on 195-45-15 Toyo T1-R's at the moment.
It is harsh high up in the rev range it's XU engine thing but it flys along.
I have had alot of mechanical issues with it but i'm almost over all of those now! It's lovely to drive out handles most things.
500 of these were sold in the uk so i'm assuming there are around 100 left on the road. Does anyone know how to find out from dvla?

Oh yes that one is on ebay as well. Could do with a loving home and a total rebuild by the looks of it.

Thank you very much.

The Zx 16v is a very unrated and rare car. I've never ever seen another one in the flesh! It's essentially an S16 but the interior imo is a dash nicer and it is a tiny bit lighter.

This one isn't really in that good condition those pictures do it justice! It's going in for a full blowover , wheel refurb and getting a phase 2 bonnet when i have the money. Then it will be looking tidy.

This is the phase 2 bonnet

Drop a Xsara VTS lump in it and give it the performance the chassis deserves biggrin

A Xsara Vts lump would be the worst choice of engine swap! Considering the work involved and the power gain. It should be running about 160bhp when all my breathing mods are done anyway. After that i'm saving up for a VTS/GTI6 head and keeping the same block(S16 block better for tuning) and going for ITB's or bike carbs. Thats all long term though.

What? The Xsara VTS lump is way better! The variable intake manifold on the ZX is way too restrictive. With a cat, the ZX will be running 150bhp if you're lucky, and Xsara VTS' put out as near as makes no difference 170bhp on the rollers in a good tune. The bottom end is nigh on the same, so if you use a Xsara VTS head/intake you've practically got a VTS lump!

You'll tell me the ZX's lump is better than the original 1.9 16v Mi16 motor next tongue out

The bottom end is almost the same but will take the power with more reliability than the VTS lump. As i've said i'm keeping my bottom end and fitting the VTS head, bike carbs or ITB's the variable inlet manifold does suck dong. However it can be made to give some power. 170bhp has been seen with little effort according to club 306.

"The video below is of a 306 s16 with a Longlife exhaust system and K&N filter along with good quality engine oil, spark plugs and super unleaded fuel achieving a power figure of 170.5bhp."

Anyway i'm having big reliability issues so the engine is being lifted next week. I cannot afford a remap or carbs at the moment so i'm going source a cheap GTI6/VTS head , rebuild it and put it back on s16 sensors and inlet if this is possible then saving up for carbs or ITBs.

Do you guys think a 6 speed gearbox is worth it at the same time?

6 speed box is worth it for the fun of it, and I've been told that 6th gear does improve the economy on the motorways.
But I've also been told contrary to the book figures, the 5 speed box in the Xsara actually makes a faster car, as 6 gears are slightly overkill and more time is lost during each shift as the ratios are shorter.

But.....I've also been told that's bks as the 6 speed box is essentially a 5 speeder almost with an overdrive. So I don't know what to believe!

Anyway, I was also once in your merry club:




But long term I stuck to it's older brother:




Just bought an old Autocar with a ZX 16v test against the Mk3 Golf GTi and the Civic VTi...I'll try and scan it in or something.

Those are mint! I really wish mine wasn't bloody silver but i don't have the money for a respray. Is that red Ventian red?

Engine should be coming out next weekend. Trying to decide between GTI6 engine or a rebuild.

We used to have one a few years ago now. I don't remember it with any fondness. Steering absolutely awful.

I'm curious as to why you believe the S16 bottom end is much stronger? I thought the iron blocks were very very similar, and the only weakness I have heard of on the GTI-6/VTS bottom end is thin piston faces, but even then I was under the impression there were a few lads with supercharged units making towards 250Bhp on standard internals? As for the 6 Speed box, the ratio's seem to be well stacked from 306's I have been in, you will lose some steering lock though due to the longer design of the box.

The block design has additional cooling for the pistons and additional lubrication. I'm not an engineer so i don't know the specifics but any serious racing team will pair a xu10j4 bottom end with a gti6 top end.

250bhp is possible on the gti6 bottom end it's just not as good as the s16 bottom end.

I've just lost my job tonight so god knows what going to happen to my car frown

You sound like me.

I had a BX 16V which had a couple of problems so I took it off the road and bought myself a ZX 16V. To be honest it was a huge let down after the BX. I wasn't too gutted when it caught fire after about 5 months of ownership.

Did the only sensible thing and got the BX back on the road and used it for a few more years happy motoring.

Ahh the BX GTI. I always remember my dear old dad taking me to the local Citroen dealer to test drive a jet black GTI. As we took it down the dual carriageway I asked him to see how fast it would go. He replied oh no son I want to break it in gently. I was slightly perplexed. Only for him to add that it was our new car. Happy day.

The 16v still looks good in it own unique way. Never got round to driving one.
