What cam is this? Suggestions for replacement?

[twin eng, twin turbs]

A couple of more questions,

How big are the valves in the "Big Valve" 8v head?

What is the spec of the G Grind cam? 268 degrees?

Any links or websites I should read?

I'll drop the head off this week and see what the go is.

The valves in your head are 38mm inlet and 33mm exhaust. If you are interested i have a fully ported and polished head identical to yours with extensive porting and polishing, new valves 38mm x 33mm, guides and seals. It has had 0.08mm machinced off the deck and the combustion chambers cc'd, polished and matched. Its perfect for a street car and is surplus to my needs so i will be selling it. pm me if your interested

Also consider the american aba crossflow heads they can make stupid power from an 8v and can run kjet

I've thought about getting one from the US, already worked, and putting it on twins probably. But then again, I don't really have money for it, so I'll have to stick to GX's and so on an so forth... Oh well.I'll live.

Really its 8v for street, but if you want something with serious poke for competition, 16vs are the deal.

The 16v head is actually quite a good head. According to a guy from Greece named Spyros (oh its getting worse and worse here isn't it? haha) who is building a 1000hp (yeah thats three zeros) 2.1L 16v, he chose the VW 16v over a cosworth BDA or BDG because they have a better head and flow better.

Beau and I were talking about this last weekend. A crazy 8v is quicker and more reliable than all but the most extreme 16v.

This is very true.

I've seen build up thread's on Vortex about ABA 8V's making some very nice hp & torque numbers both NA & turbo'd.

This is turning out to be one of the best thread's in a while.

.... who is building a 1000hp (yeah thats three zeros) 2.1L 16v, ....

just look on vortex, I've see a fair few threads with guys with ABAs on megasquirt and etc, but due to the quantity of threads on vortex, you might have to do a bit of searching.

From what I gather, ABA's are reasonably common in the US, but just shipping, and finding *just* a head that someone would be willing to send out, wouldn't make it worth while IMO.

For the money spent buying it, and getting it shipped over (due to it's weight) I think i'd be more economical monetarily, to spend the money on a head available here, and get more work done to it. If that makes sense at all.

Then again, I'm just spit balling here

GROUP BUY
if we shipped bulk itd be sweet...
im just keen on the idea of not having the inlet over the exhaust so i dont get heat soak in my DCOE

DOH!!!

Sorry Preen. I totally forgot about that .
If I was going 11.0:1 CR on a semi race engine, I'd go bigger cams, but for most people if it's a purely street engine on PULP & maybe ULP, 276's would be very nice.

Although saying that, the people that know me from my past I would go bigger cause I love the rough idle & run a bigger stall.
My old every day'r ute had a 3000rpm stall.

I've read of a 1000+hp 16VT that split in half
