Ok so Im getting a USDM motor... Its a B16A out of a 99 civic SI... here are my options for tranies ----> Y1- J1- S1... I want to stay cable... What is the diference between these tranies? Also will these just bolt right on?

i run a b16a with b16b. the b16b head flows better than the b16a, so youll have a better intake charge. the ctr head will raise your compression by .2 because the head has been decked from the factory to help establish more compression, which is aided by the pistons.
this is what i have, and this is what i will always have as far as im concerned. b18c's are good engines, but id kill for my b16. the fact is you can balance and blueprint everything you can, strengthen everything, and reinforce everything and youd be able to spin up to 12,500. but 12,5 isnt reasonable so it should come down to price. and with 1200 bucks to spare, a good top end isnt out of reach. get crower springs, strengthen your stock valves, maybe buy ti retainers, get a ctr cam with some adj gears, and spend 300-400 for head work.

Cool, cool... I am curently trying to scrape together enough cash for a 89 CRX SI... ITS SICK! It already has a JDM B16 Im gonna talk to the guy about droping the price due to smogability... It now costs me $400 to smog... Well... You know what I meen... Used to cost me only $100! WTF?

Honda/Acura Performance By Mike Kojima HPBooks
Bore-to-Stroke Ratio p65
The bore-to-stroke ratio of an engine can also affet the engine[s power characterisitics. Overquare engines, ones that have a bigger bore than stroke, have lower piston speeds and less internal stress at high rpm due to lower inertial loads. Thereis also more time to the cylinders because of the lower piston speed. Longer strokes with smaller bored engines, called oversquare, have more internal stress due to faster piston acceleration, higher piston speeds, which accelerates wear can induce seal-killing ring flutter. Undersquare engines have higher torque and low end power producing intake port velocities to ensure more complete cylinder filling at low rpm. Honda automotive engines are undersquare.

engine with smaller borexstroke needs more lift so more air can enter quicker, making more hp on the top-end.

honda doesnt make just undersquare engines. the 3.0, and new civic si engines are sqaure, both are 3.39x3.39. and undersquare engines make more high rpm horsepower, while oversquare engines make more low end torque. (that is if im not getting my terminology confused by the article you posted)

I wonder when hasport will make motor mounts for 88-91 civic/crx for the K20A, H22A and F20C? My dream is to cram a 3.2 liter motor out of an acura TL into a CRX and twin turbo the sucka! Super honda powa! Bet you could hit 8.0 1/4 mile with that setup!
