Biggest Cylinder Bore Possible

Maybe if they had a catapault to assist the take off 
Is the coconut full or empty?
LOL enough of this it's time to go work on the Supra

I contend the angle of the dangle would preclude controlled flight.

We sleved a 7m block one time, and the machinist said at .080" over it was paper thin to the coolant passage in some spots.

"Although a definitive answer would of course require further measurements, published species-wide averages of wing length and body mass, initial Strouhal estimates based on those averages and cross-species comparisons, the Lund wind tunnel study of birds flying at a range of speeds, and revised Strouhal numbers based on that study all lead me to estimate that the average cruising airspeed velocity of an unladen European Swallow is roughly 11 meters per second, or 24 miles an hour."

Best laugh Ive had all day, I love those movies. In "The Meaning Of Life" look for the "A Fish A Fish A Fish" skit, watch it and rewind it about 20 times and see if you arent laughing uncontrollably. Its so weird, but its funny as hell and it makes absolutely no sence what so ever. "A Fish A Fish A Fish.... OH HOW YOU LOVED THAT FISH...You treated it LIKE A SON!!!!
LOL

To further back up that link, this one pretty much proves that an overbore will not yeild very noticable gains at all: http://www.supramania.com/forums/showthread.php?t=44148 Like I said in there, it is used when a re-ring is not feasable, or damage has occured to cylinder walls that is fixable through an overbore.
ok, so scratch the overbore idea. What about that massive 102 mm stroker kit though? I was think that will probably move the power band down a few houndred rpms. But yes most of the time money will be spent on the head. I just want a badass 7m-ge to put in a mk2, no more turbos for me
Too much stroke compared to the bore. A stroker kit will not last you very long on a 7M, it will wear out the pistons/cylinder walls fairly quick. You want to have an engine where the bore and stroke are as close together as possible to make it last.
yes but i was looking for in the area of 260+ crank hp. Plus I already have many of the 7m parts and knowledge i need.
i bought my 2jzge w/70k miles on it w auto trans and wire harness for 400 bucks. THese engines are going for cheap.
If you are hell bent on building a NA 7m for this then great - im just saying that you may want to consider a 2jzge
You could easily wire it into your chassis and use a set of BIC motor mounts. And it will make more power....

Why exactly do you want to put a lot of money into a non turbo to only see small gains whereas you can go turbo for less and get more back? Are you just wanting to be different than most of us?
I dont understand the "NO MORE TURBOS" mentality. Just run a very conservative boost and you will make 270 HP very reliabily. I dont get it, I personally have converted over a dozen people that thought they wanted to make a rockin NA motor. I just took them for a spin in my turbo car and BAM they were converted.
Good luck with your NA project "OUT"

i understand why he wants to do it, only if i kept it na, my power goals would be over 350crank. look into the SIP stroker kit (when it comes out) and ask for whatever CR you want. im looking in the area of 10:1 right now (incase i may want to boost down the line). according to 1/4 mile calculators, 300 na whp is all you need to get into the 12 sec range, albeit on dragradials and a perfect run.
