Changing Cam Shafts and Heated Seats
Discussion
Two entirely different subjects I realise but perhaps someone could help!
As part of my S2 rebuild, I'm considering changing the camshaft in the engine to something a bit warmer since the engine is out of the car. I know some S owners have hotter cams in their cars, just wondering what cam they used and how much difference they have made to performance.- oh, and how much of a job they are to change. Like I said, I'm just after something to add a little more power, not something that's undriveable under 6000rpm!!
The plan is to get the car set up on a rolling road following the rebuild to make sure everything is working as it should.
Before someone says "buy a V8S if you want a faster car" that would involve buying another car, I already have 2 S series TVRs (well 1 and a half now) that dont work, I don't have space for any more!
The seats are also out of the car at the moment and I'm considering having them recovered. If I do I was wondering about having heaters installed in the seats (Ahem..obviously to keep my passenger happy, I'm fine with the cold.. really!)
Just wondering if heated seats were ever an option or whether anyone has ever upgraded to them?

Piper "fast road" 270 degree cam, car still perfectly tractable,but definately pulls much better at higher speed.
As Piper claim up to 15bhp gain and i got 184.9 on the rollers little while ago its bang on the nail with TVR's claim of 170 from engine.
Can be done with engine in car, I had whole top end stripped off when I did mine for a bit of a clean up and check over.I bought the full kit, comes complete with followers and valve springs, obviously heads have to come off to fit those.

If you change the seats for Jag XJS ones some of them have the heated pads in already - mine do - but I've not bothered connecting them. They also have an electrical lumbar support, with a little air pump inside the seat apparently and an air bladder in the seat backrest, I haven't connected that either.
There are I think 3 versions of these seats.
Fully electrically adjustable, which I have no idea if they will fit or not.
Manual adjustment but electric heating and lumbar support (I have these)
Manual adjustment and no electric trickery (EdT has a set of these).
If you can get the right colour (TVR used Jag colours) they match perfectly.
These are Doeskin, look here for other colours.

I believe there's a company who will fit heated seat elements and all the plumbing while you wait.
Yep, here's a link:

Thanks for suggestions.
I think the piper "fast road cam" was the one I was considering. Mike, other than what you described, did you do anything else to the engine?
The engine is out of the car so I'll be able to put it on a stand to do the work. I wasn't planning on taking the heads off as its only done 42k miles. It's also got the hydraulic cam followers which I'd quite like to keep being lazy.
I'd probably like to keep the original seats as I always found them very comfortable. - So I could go with the heated pads, but they do seem expensive for what they are!
Not sure that rubbing haemorrhoid cream on newly upholstered seats would do them any good.

On the V8 you MUST change the followers when you change the cam - they wear together (there's a running in process of above 2000 revs for 20 mins).
I can only presume its a very similar or identical process on the V6.
I would also change the timing chain as they stretch over time.
These bits on the V8 are very cheap, I guess they may be a bit more on the V6 but I still can't see them being a fortune.

I don't normally post on here now but I've got several comments about the cam:
The cam shaft pulley is furkin tight - you may find it easier to undo with the engine bolted to something solid like a chassis.
The heads have to come off to replace the camshaft because you need to remove the followers.
As mentioned, you should always replace the followers when fitting a new cam shaft.
Check with the manufacturer, but you may find that the followers have to be replaced with solid ones anyway.
I fitted a Kent Cams V6T45 fast road cam and I'm pleased with the measured results.

Again thanks for replies, not quite sure what I was thinking when I thought I could get away with retaining existing followers!
Think I'll ponder this quite a bit more before making any decisions..... If I was rebuilding the engine then I would upgrade, but given that both engines I have are pretty good and there's no real reason for pulling them apart, perhaps I'll wait a while. Especially if the work is possible with the engine in the car..
Found heated seat kits on Ebay for a much more agreeable price so that's a definite maybe. Was just wondering if I could be any more vague......

Check out a company called Waeco... they do a heated seat pad kit. Two pads per seat all wired and fused - just needs a live (and earth?)
We bought a kit (about £60) and got our local mechanic to fit them to the missus Skoda Fabia vRS. Few years on, they still work a treat. Toasty.
Blog entry from Nov 2008...
Heated seats retro fitted.
Car is an LE so has leather, and bloody cold at 6am...
Waeco heated seat kit - MHS-50 from MPS Trading - 01273 512400 for £56.75 delivered (they only do next day!).
Kit has two pads per seat, comes fully wired up with buttons (2 heat settings) and fused, so just need to fit it and attach to live.
We got our local coachworks to do it for us, and he fitted the pads, installed the buttons and wired it to the fusebox as if it was an OEM install for £240.
So for less than £300 all done and fitted. Takes a little while to warm up initially (few minutes, and not as quick as the ST220's heated seats) but they do get nice and toasty.
Worth every penny

I'm not pretending I know - does it have gears instead or was that just the older 3 litre essex that did?
