still haven't dropped the ball on this, just in Afghan right now, but anyone is more than welcome to give it a go. I think that this would be really great for the community, and that is probably my biggest motivator "how cool would it be for everyone here to have a cast iron or steel head, at a reasonable cost"

i made a conclusion..
if we are really gonna make steel heads, they need to be for the TDI engine..
it would be much easier to cast and machine a TDI head. plus, you would be able to make twice, if not 3 times the power of an IDI..

the idis are swell and rev like a gas car but thats really the only advantage, the tdi is better in every other way, once i have my jetta together, i still want to build a franken engine for it and shoot for 200hp, but after that i am moving on to tdis or gas engines(still daily diesels tho haha)

im ready to build a supercharged 16v gasser..
sure our diesels are cool, but ive got a turbo rabbit, and a diesel datsun pickup. i need a gas car again.. and a fast one, my buddy bought an SRT-4, so i gotta make a S/C Jetta keep up with that.
shouldnt even be hard, those cars arent even 250 hp stock.
im thinking my 16v ABA will be 250 hp if it runs..

250 should be cake for an abf clone. as much as i would really love to have an iron head and see what one of these engines could really do, it just isn't cost effective, and the markets too narrow for them to ever have a decent price.

yea, the diesels are a rare breed, and people tuning them, even more rare..

I'd buy one.
If someone gets a head scanned into 3d, I want a copy. Curious.

If we are going cast iron could we make it cross flow??? use the same stock intake and hope to clear the IP and injectors??? Just an idea:D

to go cross flow you neeed to rotate the prechamber and injector and lean them a bit to clear the intake runner.
the isuzu(crossflow) has injectors leaned over to clear, and the prechamber points off-center of the piston(and the piston top has the cloverleaf cut differently)

There's no way it the intake mani would clear the injector lines though. Try changing the GP's and imagine a manifold sitting there too
.
With a steel head you could probably get away with less metal here and there making larger runners possible.

one of the biggest motivators to moving to a steel head, and he is right, making a cross flow 8v head would require the modification of a lot more than just the head, I need a print, or someone that can do auto cad to measure and print the head so that we at least have that out of the way, I was just going to have the foundry do it, but for time constraint purposes, and also the idea of an enthusiast forum having a 3-d print of such A THING AVAILABLE TO THE WHOLE COMMUNITY COULD MAKE tuning or modification much more visual. shoot, I'm no visionary, just making a suggestion here. OH! btw, greetings from ramstein AFB Germany folks, don't worry, just passing through on my way back to the battlefield to fight the zombie hoardes in Afghanistan.

i still think we should all just switch to TDI.. then we could have a cast iron head, and the possibility of 80+ psi boost, and 4 or 500 hp..

make it cross flow will require alot of engineering and r&d, just getting one made from iron is big enough of a chore really. but i agree beyond a 200whp goal tdis are where its at.

Seen chalked on the back of a Marine LAV
"do not brake for Taliban"
Is that you Kevin? It was spotted by a friend of mine working in the Marine AO.
