Hi guys,

The next cosworth journey that I am about to undertake is the 400bhp+ engine. the figure is chosen as a benchmark. Slightly over is fine, slightly under misses the point.

I had a fascinating chat with Chip and a couple of others at the last WSM meet, and I want now to refine my shopping list of bits, and stuff so that I can work my way to this target.

To keep it simple, questions are posed as follows. Further info is below...


1. What work needs to be done to the head itself? internals below

2. Standard cams up to the job? If not, any recs?

3. What valves, and what followers?

4. The block currently is 200 block, mahle pistons (std comp), +0.5 oversized to be sure, all fully balanced bottom end. Runs cometic 3 layer gasket with no trouble.

5. Turbo is currently T35. Proposing to change for a T38, as per chat with Chip and Doug.

6. Fuelling will be from the newly acquired Group A pump. What about regulator - does this need anything? Also which injectors?

Once I have the engine essentially built, I will prob take her to one of the tuning chaps for a live map, which it will clearly need. Anything else I have missed?

Thanks all in advance!
