I can't believe nobody has asked if you were planning on using a cardboard plenum lol. We are still on honda-tech right? Looking good! There's gotta be a mini pro stock scoop out there somewhere.

very clean bro

crankshaft came in today





im sure you guys know this is a 95mm h23 crankshaft from the non vtec prelude.

here is a little known fact:
there are actually 2 usdm 95mm h23 crankshafts available.

this particular one is from a 94' and up prelude. the other is from the 92' prelude. and both were available on the 93' prelude.

here is the queston of the day: anyone know the difference between the two usdm h23 crankshafts?

IMPORT JEDI

newer ones have bigger mains

fukenricen

love it , nice keep us posted with more pics

NAH2B

NOPE
this would be correct if we were discussing the h22 vtec crankshaft which was given larger 55mm main journals when the blocks were changed from closed to open deck in 96' or 97'.

but they stoped production on the prelude non vtec (h23 crank pictured above) here in the usa before giving them the larger 55mm main journals or open deck block.

now the jdm h23 vtec does use an open deck block w/ 55mm mains, but it wasnt available here in the usa.

anyone else care to take a guess?? i will give you a hint. anyone whos ever removed the crank pulley from a 92' and also a 94'+ prelude may have noticed the difference haha

Turbo-charged

one is more awesome than the other?

NAH2B

haha

yeah one has a special coating which will hold up to the kind of power Joe makes

actually the difference is the newer crankshafts have the snout drilled and tapped for a larger diameter bolt.

although i couldnt tell you why honda decided to do that?? maybe they had an issue w/ the bolts snapping or coming lose? im assuming the larger bolt will allow more tq to be applied during tightening. i do know i have seen h series bolts back themselves out before for no good reason.

just thought that would be interesting to all the h series guys out there lol

anyway, i will be droping this crankshaft off at the machine shop soon to make sure it is balanced to 10k rpm. not that im sure i will be shifting that high, but since i had one break on me before i want to make sure we take every precaution this time around.

here is another cool part which showed up in my mailbox today:



braided clutch line to help clean up the engine bay


and here are the pro 3's which ive had laying around since sept. THANKS TONY



cant wait to see how these things perform.

one of the goals w/ this build is to shift the powerband upwards a good bit. im hoping the custom intake and exhaust manifolds along w/ these cams will be what we need to make it happen.

wheres the pics of the maquina motor

NAH2B

the motor isnt assembled yet obviously

but the block is already sleeved thanks to Jim Justice

im just waiting for the custom pistons to come in before the final bore/hone can be performed. then i will start assembly.

dont worry, i will post plenty of pics as more parts arrive (everything has been ordered) and during assembly

i do have some other parts laying around so maybe i will get some more pics up tomorrow.

fukenricen

yah take some pics once the block is completed

Randy FWIW, i remember talking to Jeremy L. last year about larger cranks and he said that he had a problem with snapping the crankshaft bolt while motor was running so on his larger billet cranks ( like the one i had) he actually used a completely different bolt/thread pitch to try and resolve that problem. Maybe honda was dealing with same issue

nitrousballa

prototype WILSON MANIFOLD....man that head and manifold must be really special " thumbs up".

NAH2B

its very possible. i dont see why else honda would go to a larger bolt?

NAH2B

here are some more pics of various parts i have for this project:

custom fuel rail from Shawn@ Rosko racing:



balance shaft block off kit also from Shawn:


plenty of -6 and -10 hose and fittings for fuel and breather:



breather tank:


seats and harness:



also got a set of black tweed covers


wideband and alt wiring location on chassis:


view of guages:



the integra dash fits cleanly over the guages and the cluster bezel was trimed to fit. the only other thing on the steering column will be the bideband display.

hope everyone likes

Nice. Can't wait till it's all put together.

RobbieG35

Very nice. Car was sick before, can't wait to see the end result.

rota92

I love build threads! Looks good!!

DaveF

what are the plates on the shock towers for ?

rota92

I dented the crap out of mine with my Upper Control Arms, maybe they have it so it doesn't dent it?

DaveF

i dunno ? wouldnt they limit your travel slightly ? i thought the oem metal is like a peak in that area ? i know when i had my car as a street car, with the coilovers all the way down it would hit once in awhile, but that **** was rediculas low.

rota92

Yea it's a peak, maybe they came through theirs lol I know I was close to it, wheelhop owned me

DaveF

was that when you 1st started running the car ?(like street car status) or more toward the end of the "d-series era" ?

it happens a lot on street cars that are really low, you hit a bump and the upper A-arm hits the inner wheel/fender well there
