interest: 34/30 steel head

[R.O.R-2.0]

Yeah, I suppose the 6.9's would be massive. There's probably something that'll fit though

And I'm not on the island, I'm about half an hour out of Vancouver

maybe some nissan 2.2/2.5 precups, or something along those lines..

OR!!

some mercedes precups! people seem set on running merc injectors, so lets get some merc precups in an engine too..

[macka]

the merc 2.2 would be a nice fit, with very little mods needed.

[Kudagra]

Merc Precups would be the only way Id run an IDI when this one goes tits up. The Merc precups screw in from the top so there is no worry of them falling into the pistons and destroying your engine.

Press in precups on the cylinder head deck is just stupid.

i am wondering more and more how necessary a steel head would be, look at powered by spearco hes doing 200whp with out nitrous no head problems, same with daves franken engine, no head issues unless you count the precup that melted into the piston, but thats an injector issue.  the other thing too is if there is going to be a 1.9 head made from iron or steel, its going to cost alot, no matter what its going to be expensive, so modifying it in anyway is going to jack that price up, alot.  i think the best thing would be to have an aaz head professionally ported and then have that head used for making the castings.  the swirl chambers are not an issue on these engines, and the injectors are not either, why change those things.  k.i.s.s.

well, the iron head lets us run ~80 psi..

i suppose that would be interesting haha.  i wonder how much is even reasonably possible, sure cummins and power jokes can do 1000hp or w/e but they are 5-6 times the displacement, how ever they do only rev at half the speed our engines do, so i suppose the amount of air they move in n/a form is only around double what ours would be, so with an iron head maybe 4-500hp is reasonable

my sentiments exactly, that is the general plan.  stay simple.  aaz print, cast, done.  you want porting, get it done, you want different chambers get it done., the head can thus be welded no problem, and machined, as well so anything will be possible once this thing goes through.  plus there will be the possibility to tinker later, "for the more serious demons" for whatever they can afford.  The object is to get the most for less, which means keep it simple. and VERY stock.

[R.O.R-2.0]

looks like we need to build 2 different heads..

a stock AAZ idi head

and a performance 16v TDI head. too bad we couldnt use the 16v head and put fuel injectors in the spark plug holes..

[NintendoKD]

lets do it, I see no reason why we IDI guys should keep all of the fun for ourselves.

[R.O.R-2.0]

well, TDI is alot easier to machine. theres no swirl-chamber..

and we honestly wouldnt even need glow plugs for such a hot rod head..

[NintendoKD]

When do we do this?  I want to get started right away.

[DJPyro]

I'd be pretty pumped about the idea of a TDI head to do an mTDI swap on my AAZ....

bolt a TDI head on it then... AAZ and early TDI are the same engine block.. just gotta change the AAZ pistons to TDI pistons. and use a TDI head of course.

[DJPyro]

Well I realize that, but they're $1200 new (there's one new one in NJ still ), and I haven't been able to source a decent used one locally yet. However, if there's discussion being had about a performance head, and it's comparable to a new head, or refurbishing a junkyard head with an unknown history, I would strongly consider it.

[R.O.R-2.0]

i imagine these heads are going to cost $2-3k in all reality when all is said and done..
