Can I fit the 24v Cosworth V6?
Discussion
Mickey,
If you are thinking of using V8S trailing arms instead of the S2 arms based on their ability to take greater power output, I would consider having these further strengthened as PH has had to have done with his after breaking them.
What diff, half shafts and CV's are you going to be using ?

I wanted to take advantage of the wider track that the V8S has as well as uprating to discs on the rear. I shall be using the beefed up cosworth drive train with a T5 box if I can find one.I already have a nearly new LSD so I shall use that.
Had an interesting chat with a guy from Wedge this morning regarding "poly" bushes. He strongly recommends that original TVR bushes or nylon units are used and definately dont use Powerflex or superflex products as they will seriously affect the handling of the car. A lesson for us all I think. He recons they are just too soft for the job.
I seem to recall reading about braided cooling hoses somewhere on the site? can't remember where, was it a Leebee mod?

Burton are at:
www.burtonpower.com
or at least that's what their current catalogue says.
They have had problems with the site in the past - the price list option didn't work too well!
Call them on 0208 8554 2281, fax is 8554 4828.

I have poly bushes for all the trailing arms on the car and found they improved the handling of the car. I wouldn't want to go any stiffer than these though. It depend largely on what you are going to do with the car. Mine is everyday transport and therefor I'm not looking for the 'ultimate' set up. Mine is already has a stiffer ride than most.
As for braided hoses, someone mentioned their wife was getting them a set for Xmas. I can only think that they must have had them specially ordered. I have replaced some of mine with Samco silicone jobbies and will continue to do so. Braided hoses are a lot of money and I don't see the advantages over silicone other than the aesthetics. There are sevearl companies offering the service of making braided hoses to your spec.
We must have missed each other at the S meet, it would've been good to have had a chat about this car as it seems rather special. Any pictures as to where you are at the moment with it ?
I've had a number of ideas for another S meet and will subject them to public ridicule or rejoice in a couple of weeks.
Cheers

You can get poly bushes in various grades from really soft (like the original rubber ones) up to almost solid, same as nylon. So you should be able to get the right grade. I can't tell you what grade they are, but I've got poly bushes all round (from Tower View), they're fine and made a noticeable improvement over the rubber originals. Big advantage of poly is it lasts much longer than the rubber ones. Nylon (or equivalent) bushes are fine for a race car but way too hard for normal road use, also they had a reputation for knocking the chassis mounts oval which is expensive to repair. So go for a moderate grade poly if I were you.

Be careful here as the V8S has wider bodywork to cope with the wider track so you may find that the rear wheels will foul the bodywork. Before paying out you might want to chcek first. You could stay with the V6 arms, strengthen them by all means, and then fit wider wheels which will also give you a wider track by default. You can always use spacers if necessary as well.

Don't really like braided hoses for cooling as it can be almost impossible to tell where a leak has occurred and you have no way of seeing the condition of the rubber pipework.

I know for a fact that adjustable trailing arms will fit on the V6 powered cars as I have fitted them (and will be doing so again this afternoon!), but are there 2 different types of adj trailing arm?.As far as the V8S is concerened (I might get flamed here!?!) the track is the wider aspect as the trailing arms give about 15mm (each side) more width and the front wishbones are noticeably wider (this is why a V8S bonnet will fit on a V6 car but the wheels stick out at the front on the V8S). The distance between the chassis rails (i.e where the engine sits) is the same on the V6 and V8 (unless my measuring equipment was lying
).I am not saying that the chassis and body shells are the same though as they are clearly not

MMM,
I'm a bit confused chaps
,are we now saying that you can't fit V8S arms to a V6 car. Leebee, what do suggest I do regarding these arms. I would like discs on the rear for obvious reasons but I will take your advice, perhaps you would let me know.
I don't recall the body shells being any wider, not heard that one before. Can't imagine TVR making a seperate mould for 15mm difference in width, anyway the V8 bonnet fits onto a V6 Shell. I know that coz I've tried it.
Johno,these silicon hoses,did you get them from Demon Tweeks or Burton?, or are they specially made for the "S".
Thanks for your help guys.

I've had an S3 and now have a V8S and I'm fairly sure the body is the same (not a lot of space in the garage, so I have to get it just right). I have always been led to believe that the V8S (and S4) had a different (stronger) chassis and wider track. As Lee says the V8S wheels, which are the same size as the S3 fill the arches more and stick out slightly, whereas on the S3 they were tucked inside.

Ok...
I am not saying that you can't fit V8S arms to a V6 car but if they increase the tracking, they will physically move the wheel out. This to me raises the question of how much space is there to cope. The V8S does have a different body/chassis compared to the S1/2/3 and one of the changes was some accomodation for the slightly wider track. The wheel arches are slightly more flared according to TVR IIRC.
All I was doing was to flag up that it might be worth checking what a V8S arm would do you on your car especially as you may need to fit wider tyres/wheels to cope with the power increase. It could be that it is so tight that it may not be possible. Better to discover that now rather than later. Also be aware that TVR often fitted the bodies on slightly offset and so clearance on one side means it fouled on the other. This caught me out big time on the 520. The side I measured had the clearance but the other didn't. Ended up having to do some creative wheel arch sanding to get a a mm or two clearance.
If Lee is fitting some, then a quick set of measurements to work out the wheel clearance is all that is needed but it could save you from a costly mistake. Hence "might want to check this" comment.

A quick call to the factory, I think, has cleared the confusion!
The V8 indeed has a wider top chassis rail to accomodate the rover lump, however, the front wishbone mounting points are in the same location and are the same distance apart. The additional width to the front tracking is made by longer wishbones.
The rear semi-trailing arms for the V8 are also spaced to allow fitment of the rear discs / calipers.
The front and rear track on the V8 are boththe same 20mm wider each side - 1438mm total. The body dimensions are also the same, the main difference bewteen the 'tubs' are that the V8 footwells are smaller (lass wide), again giving more room for the rover lump.
The V8 chassis is strengthened through the center section. I don't know if this was mainly due to this center section being wider for that rover lump again!!!!
To fit the wider front wishbones you also need a different steering rack (these racks are currently not available from TVR parts dept.)Also, a different spring rate/length was used (and is advised to be used) with the wider track.
.. Hope this helps!!!!!

I have replaced like for like with Samco hoses from Demon Tweeks. I have just replaced the top and bottom radiator pipes for the stainless ones made up by Tower View and took the opportunity to replace the old rubber pipes with silicon alternatives. I will be changing the whole lot once I get some time. I replaced by ordering lengths of the necessary internal bore and cutting them to requirement.
As I sit here now and think, there is only one hose that is pre-shaped and therefor more difficult to replace. I agree with Steve's comments regarding braided hoses and leaks. I have tried to find out what all the various internal diameters for the all the pipework is so I could order before removal. Unfortunately I have been unsuccessful, so will be stripping and measuring in the near future. Once I have all the details I will post them on here.

"Currently" meaning "never will be.." as the factory prodcing them went under some years ago... recon's the way to go although I did find a brand new rack for my S2 on a shelf in a TVR dealer in Yorkshire a year ago.. he'd forgotten he had it...

On the subject of pipework...
Santa bought be a rubber pipe guillotine tool (made by Sealey) cost about 16 pnds from DTweeks. Very useful if you are playing with rubber pipework as it is so easy to cut pipes easily with it.

Steve,
I'm presuming this will cut Silicone pipes aswell ? Also how does it deal with Flexipipe ? As the Samco Flexi stuff comes with a metal coil inside for additional support. I used a very sharp hacksaw and got an acceptable finish with use of a gas lamp to tidy up the frayed ends, but if this tool can do the job it would be worth £16 !

Hi All,
Project is progressing well. I have most of the bits required to build the car now except a T5 Gearbox, but that is just a matter of time, but was just wondering if any one has any experience of "Wilwood" braking systems. If you look on Rally Design's web site they are offering a Sierra Kit for £567 including discs. That seems good value for money to me as AP Racing's version is over £1000.
Trouble is I have no experience of such items, does any one else or has any one used anything similar?
Also, does any one know of a modular alloy wheel manufacturer other than Compomotive. I want to duplicate the TVR standard 7 spoke wheel (as much as possible) but in three pieces, so the spacings can be played with.
