Cossie 24V in TVR S2

[Vervoortski]

This weekend I finally started on the 24V engine: I had some sturdy steel and castor wheels lying around, so i got out the welder and built this...

An engine stand! Makes it easier to overhaul the engine before it goes into the car.

Garage? It's in the kitchen!

I've put a 24v into an S2.

Work on the 24V is not going quick, thanks to the TVR demanding attention in other areas too, but I've found some time to start with the exhausts manifolds. The manifolds of the 12V are a tight fit as the engine sits in the small space between the both footwells, and the Cosworth will be even worse. The tubular manifolds run along the chassis rails to the front of the engine then go down into a collector, and to the rear from there on, so the 24V's standard manifolds will never fit.  What I'm trying to do, is modify the TVR manifold's flanges, so that they will fit the Cosworth. I finally sourced one set of manifolds from two different TVR owners (cost me 12 pounds and a bottle of rum, a bit less than forking out 800 pounds for new ones). Trial fitted them to the Cosworth this weekend. This is what it looks like:

Nice idea, but the manifold on the left bank is too long, and the one on the right is too short. I may have to modify a bit more than just the flanges. Then there's still the alternator to be fitted. With the footwells, chassis tubes and exhausts taking up most of the space next to the engine, there's little space left for the alternator. Maybe i should fit bike dynamo's to the wheels?

For almost the same reasons I have been looking into putting the alternator where the aircon pump originally was, could that be made to work in your case as well?

I sell a pair of cast iron headers that fit the S2 and the downpipes drop down behind the timing chest and link into the system under the car.  They don't come forwards at all.   I also sell an alternator relocation kit which raises the alt to clear the chassis rail.  Pics of the headers are on the 24v page of my site, bottom of the page.  Downside is they cost a lot more then £12.

Hope it helps.

I had seen your manifolds Mike, they sure look the business, but a bit over my budget. If it doesn't work out with the tubular manifolds, I'll have to start saving up for them.

The tubular manifolds come down both at the left and at the right, so they also take the space where usually the aircon compressor sits, so that won't work. There's two possibilities: either find an alternator that turns the other way and mount it next to the waterpump, facing away from the block (plenty of space in front of the engine), or fitting an idler wheel for the ribbed belt above the manifold and fit the alternator above/next to the manifold.

Good luck Vervoortski:)  I thought about a rearward facing alternator but didn't pursue it.

If you get stuck bear in mind I don't charge vat and could send stuff as a sample
