overall is an s2 more desirable? with dual circuit brakes, hydraulic clutch, 4 shock rear suspension (not sure if that has many advantages)

as i understand the s3 doesnt have these features as standard (not sure re the brakes), although by now most will have been altered to some extent

As far as I know. all S3 had dual circuit brakes - mine did, although I had to use a different PDWA to replace it.

S2 rear setup can be fitted fairly easily (I did that to mine on its rebuild)

My S3 does have a cable clutch. Personally I prefer cable clutches, but your choice !!

Not sure if S2 is rarer now ? Not sure about prices....

My S2 has simple single circuit brakes and no servo with the old TVR biscuit tin pedal box. East to upgrade if that's what you want.

Hi Andy
How well does that work my S2 has a servo but the Tuscan is the same as yours rather wish it was the other way round although yet to test the Tuscan but I think upgrading the brakes will be on the to do list shortly.

i would think due to the overall light weight, a servo would not be necessary?

60s historic racing may make the S2 more in demand

purley aethetically i do like the earlier side grill on the s2, over the s3 zodiak ones

I don't think the servo is essential either. Doesn't make the actual braking any more efficient and obviously adds weight - you just have to stand on the pedal a bit harder, which is a little disconcerting when you first tread on them but you soon get used to it.

Andrew if you want to save your leg muscles when slowing down that big V8 then it would be possible to fit a remote servo. I'm pretty sure you can mount it anywhere where there might be space in the engine bay (but not on the engine itself). Some plumbing required but provided you have a tapped hole in your inlet manifold to take the vacume pipe it shouldn't be that difficult.

My S3 is a very early one so still has some bits leftover from S2's.
Mine has a servo but i run with it not connected because with those big 10.5inch discs up front I find it overbraked and easy to lock up in the wet. I find that running with the servo disconnected gives more feel and confidence to the brakes.

Mine is the last S3. I find it odd that TVR changed from hydraulic clutch on the S2 to cable on the S3, I'd have expected cars to have developed the other way round. It would be interesting to know the reasons. However I have no problems with the cable.

Likewise, I do personally prefer the S2 side vents to the S3, but then the S1 (Grantura) teardrop shape were so much prettier than both. As were the Cortina Mk1 lights compared to the Mk2. What TVR should have built was a lwb Vixen with Mk1 lights, rounded window frames, Grantura side vents and dash switches, overdrive and engine.... well I'm still contemplating that one but a super charged crossflow would have been interesting!

agree with that

The S3 is a little rarer, 168 built compared to 438 S2s - according to the Vixen register.

I think the finned alloys became standard on the S3, also the S3 has slightly more power.

I may well be wrong but I thought both the S2s and S3s have the four shock rear suspension and the Tuscan V6 has the four rear springs as standard. I'd be grateful for clarification on this.

I also prefer the S2 side vents.

MY S3 had only one pair of shock/springs when I bought it, but it had 4 brackets on the chassis. I remember that David Gerald did say that the S3 had a 'short' bar for only one shock, and S2 bars were longer for two sets. Of course there would be an overlap between S2 and S3 so I guess this will probably stay a bit hazy...

I think the S3 had the 711M block ?? Again probably some overlap...

The cable clutch was really a mod to the original, with a bit of extra bracketry, and it would be easy to go back to hydraulic if you wanted. I'm pretty sure my S3 has a TR6 pedal box, servo + mcyl is TR6.

My S3 is LVX1744/4 which i believe makes it the 3rd one produced. It had short pivot bars, single coilovers at the rear so I suppose this is one area where TVR made a "clean" change between S2 and S3.

Mine was 691M engine (capri GT) with hydraulically operated clutch.

To change from cable to hydraulic you would also need a different bellhousing and release fork.

Mine is 2123/4, so is a lot later.

Oops, yes, one would need matching gearbox/bellhousing for hydraulic, I meant easy at the pedal box end...
