Few updates since Zilvia went down.

I wasn't happy with the hotside of the car or the engine bay.. so I made some changes, bought a Kazama F1 Manifold, had it polished and redid the exhaust.

The entire system is stainless now and I kept the Kakimoto muffler as it's the reason I bought the car in the first place. I also deleted the blow off valve at the same time.

After that put it on the dyno and it made 15kw extra at same boost.

So after the dyno the tuner gave me a whole heap of ideas and there was some valve float at higher RPM (hence not running much more boost). Whilst he said it was totally safe I didn't like the idea of driving the car hard with the issue. So next step was;

Kelford Cams 264/272, Springs, Titanium retainers, and maintenance wise we basically replaced everything on the front of the engine. At the same time we vapour blasted quite a bit of stuff and did a whole heap of maintenance. We also replaced the valve stem seals.

I keep saying we, I did none of the work lol, anyway - some before/after

The car sounds crazy with cams but I'll wait until its tuned then post a video.
