What's a btcc cylinder head got ?
No VVL, it doesn't even have VTC, no shaft mounted rocker arms, ports are clearly smaller
It's not hard to work out which is the better cylinder head
The ve head change The game for sr20's
Scorch s15 very impressive time attack circuit car which holds the record at 52 seconds around Tsukuba circuit track in Japan
Now take into account this rear wheel drive car is faster then 4 wheel drive cars
MCA s13 fastest rear wheel drive car at World time attack in Australia placing in at 3rd
There are 4 or 5 drag cars running in the 7 second bracket and micks Motorsports running in The 6 second bracket
All these cars run sr20's and what do they have In common they all use ve heads
Its the most responsive cylinder head due to its VVL and massive ports
It's the most reliable cylinder head due to its shaft mounted rocker arms
The amount of extra timing my engine took after the cylinder head conversion was amazing
My tuner said its more like tuning a Honda then a Nissan
My car makes 300kw on 10psi at 4000rpm how many sr20's do u know of that can do that ?

Proof. Let's see some REAL proof, let's see some side by side dyno's with the same setups, until then you have no proof to say the VE head is better than the BTCC head. Until you have some solid proof, gtfo.
