It will also have a 5 stage dry sump set up to handle the oil pressure and the stock water pump will be removed and replaced with an external unit to help cool the head down.
The head will have everything replaced and it will be converted to a solid lifter head.
In all reality, 10k rpm's is not to bad with these 16v heads.

What are you looking to run for bearings? OEM trimetal will nuke at 10K as local bearing oil temps exceed their operational temp.
I would HIGHLY advise not to run a 10:1 ratio, your dynamic pressures are going to be a bit high for even race fuel. You might look into a second small sump that injects methanol along with the nitrous to aid as a secondary fuel source. If you need more dynamic compression you can always adjust your intake cam gear to shut the valve a bit sooner.
10K RPM isn't **** to these short stroke / mod length rod engines. I would advise using Cunningham's 296K PSI rod bolts, they hold up to captain insane-o amounts of RPM and are better than anything ARP stocks.
I would not run an ITB head. You will get better results with a single large throttle body because the individual plates become large sources of aero drag in the runner. They also create wake which can become turbulent at specific flow volumes.
PM me the turbo specs.

Clamp that head on tight. What were the boost numbers on the old Formula 1 cars? They made big hp from less than 2ltrs.

No Doom mainfold for me. It will have ITB's.
In the 80's they would run 1.5ltr 4 bangers and had anywhere form 1200-1500HP..

You wait and see. I will post pics and you can re think you suggestions. This is not a Nissan. j/k But, I do welcome your or anyones suggestions.
This has been a well thought out motor. All my choices were not guesses, trial and error or theories I learned from the internet.
I have a reason every choice I made and I promise to explain them as the build continues.

I believe you'll find that you can get more HP from lowering the CR and upping the boost even more.

See, that's what I was thinking. Lower that CR to a meager 8:1 and crank the **** outta that boost.
According to R&T, BMW in F1 ran as high as 5 bar absolute boost (or about 58 psi gage) to net 1500 hp from their mid-80's F1 car. But in race trim (making only 1250 hp) BMW ran just over 4 bar absolute (or about 43.5 psi gage).
And that was all w/ a dinky little 1.5L 4 (or V6, can't remember).
Apparently, Piquet (who raced BMW F1) also would race a Ford-powered, 1200hp car, and at NO time in the whole length of the race did he ever use full throttle!

What a joke. (cue in the ******* crew to tell me I don't know what I'm doing).

C'mon Drifto don't always jump to paranoid conclusions. If Dave is confidant about making this happen just wait and see. As he said he's happy to hear yours and others ideas but you have to let people go their own way and do things the way they believe to be the best. Just like you would.
Oh and the nutcracker squad have been rather quiet of late you may have noticed. Maybe they'll resurface just in honor of you. lol

YOU DON'T KNOW WHAT YOU'RE DOING.
Evil 944t needs my racing experience to build this motor, not the hopes and dreams of a drunk 15 year old ricer of your stature.

I've noticed you're a very angry person, Drifto...
There are more than one way to build a high-performance engine, and just because someone disagrees w/ your tenets does not necessarily make them wrong.
That said, we have now entered a realm of automobiles about which I know too little (big-power engine building), so I will keep my mouth shut
Who knows, if evil 944t pulls this off, we'll have learned something valuable about engine building and maybe you won't be so quick to criticize in the future.

It's not like I told them about your **** virginity being lost to a 450 lb. bus driver from Memphis while he was on tier 16 of a level 42 powerdump.

I'm not being a critic, I want to know what he is doing so I asked questions. If he wants to take that as a personal attack then whatever.

Where's your N/A at? You're making assumptions about Dave's knowledge on the subject yet you're driving around an N/A? Dear lord. Get a clue. (I'm going to get killed for that one.)
