FM Wisecos, ETD rods. The rods have 7/16" ARP2000 bolts, have been lightened, shotpeened, cryoed and micropolished. ACL "black" racing series bearings all around.

What turboz and boost you planning on using to stuff air into this bad boy?

Its going to see about 1-2psi of natural boost. At 12:1 compression, I don't think it's going to like it if I slap a turboz on it.

It's nice to see our bailout money put to good use

Nice work Dimitris. The soon part of your signature finally coming true?

Sorry to disappoint you, no bailout money involved. I've worked to earn my money fair and square.

I've been measuring 105kPa (with 100kPa baro) as it is at high speeds (110mph or more). With a proper scoop, it could go as high as 108-110.

What else are you going to be doing? I just scored a whole VVT motor that I will be getting the head off, so our setups should be pretty comparable. Any plans for cams or exhaust cam gear?

I am hoping the duct I am making from the turn signal directly to the intake will help with this.

Everything in my sig and then some. I've been collecting parts for 4 years now.

FM Wisecos (11:1, +2mm)
Further head shaving to 12:1
ETD rods as previously described
Reworked crank (lightened, conservative knife-edging, balancing)
MiataRoadster billet steel oil pump gears and pump w/external oil pressure adjuster
ATI pulley
Ishihara-Johnson full contact crank scraper
Standard MBSP
Additional baffles in the oil pan
+1mm Supertech SS intake valves
Standard sized Supertech SS exhaust valves
Supertech springs w/titanium retainers (56lbs)
Custom cams (I have 2 blank intake cams from MMD as well as 1 blank exhaust cam, so I will try two different profiles on the intake)
Jenvey ITBs with a Bob Boig cast intake adapter and a MiataRoadster phenolic gasket
RB 4-1 header (but I'm already looking for a big boy replacement)

I have signatures turned off because my shop computer is on a crappy wireless service and some people, who will not be named, decided to put a 1Gb kitten mittens gif that slowed my computer to a hault anytime I would go over his post. Thanks a lot Scott.

Your setup is a little more in depth than mine is. I am very interested to see how it turns out. Do you have a projected completion date?

Same as Duke Nukem Forever: When it is ready.

Oh wait, Duke is going to be released in less than 2 months. Damn, I better hurry up.

Well if you're going by Nukem Forever I wouldn't be too worried. 2 months is up to interpretation. It really means somewhere between two years and never. Hopefully your eta is more reliable. Lol
