i want to run 84mm 12.5:1 pistons in a non sleeved gsr motor if i add a block guard will this be ok to do i realy want to have it sleeved but that is a lot of money and if i can get away with not doing it ill run the block guard. i also want to run a 55 shot of zex if that makes it any worse.

 

84 mm on stock sleeves is insane. sleeve.

 

Can I have your motor after you blow it up? 82mm is max on stock sleeves. 55 shot 84mm bore stock sleeves = BOOM!

 

You have to sleeve it to get an 84mm bore on a B16 or B18. We sleeve and build these all the time. The stock sleeve wall thickness isn't there.

 

84.5mm and 12.5:1 here and after 15k miles o far so good 234 whp daily driven pump gas!

I think the guy is referring to stock sleeves on a gsr block. Max Bore you can go is 82mm. I don't know how you run run 84.5mm on a stock non sleeved gsr motor 15k miles unless your running a b20 block.

 

ok ok can anyone recomend a shop in washington state where i can get my gsr block sleeved? and i have heard u can hog out a stock b series to 84mm but if u guys say its 82 ill belive ya. well hhmm if im gunna sleeve it i might as well go with 86mm right? i guess my goal is 240 all motor hp at the wheels on pump gas ive got a gsr block and a b16 head help!!!!

you can go to 84mm .. BUT YOU HAVE TO SLEEVE IT

86mm? Why not just got 89

Sleeve it to 84.5mm or 85.0mm.

240hp? What internals do you plan on running? Better break out the wallet or VISA

 

well fully balanced knife edged and micro polished crank eagle rods and 12.5:1 pistons and i live with my parents and have no bills o i have a few bucks to build a motor with say 86mm pitons in a gsr block and b16 head how big would the motor be? 1.9? 2.0?

bigger than 2.0.. roslyn huh? thats deep! i also live in washington, sent my block to california but i'm sure there is shops that can do it here.. just have to find a reputable shop good luck with the build! you planning on going to pacific raceways next season when you get it finished?

 

Displacement = Pi(3.14) x 1/2 R (bore) squared x H (stroke) x 4 (# of cylinders)
Motor you are talking about = 3.14x 4.3(1/2 of 8.6 centimeters) x 4.3 x 8.72 x 4 = 2025 cc's.
All bore/stroke numbers are in centimeters because you are looking for displacement in terms of cc's (cubic centimeters).

???? haha ive been out of schoolf for awhile. could you put that equation in laymens terms? haha
ok so its pi times 3.14(or are you stating pi is 3.14?)then multiplied by 1/2 of radius(stating radius is the bore?) then square 1/2 of the bore correct? then multiply the stroke multiplied by the cylinder?
or lets do this easier
pi x (1/2 bore squared)x stroke x #cylinders?

 

Pi is equal to 3.14.
The radius is the bore.
You take 1/2 of the bore and square it (times it by itself-i.e. 4.3 x 4.3 on a 8.6 centimeter [86mm] bore).
H (height) is the stroke-on a GSR/ITR it is 8.72 centimeters.
Once you multiply this all out, you have the volume of one cylinder. Then you just multiply the volume of one cylinder times the number of cylinders in the motor.

So what you have is correct

 

JG does 83mm with block guard on customers cars and they said they havent had a problem yet....i say do that

Try Action Auto Parts and Machine @ 206-522-1822. They are in Shoreline, WA.

 

i usually go to renegade raceway just outside of yakima pacific is expensive and u get very few runs in. i do plan on making a few trips to pacific this spring though. yeah roslyn is deep not many tuners out here mostly on this side u see alttezzas aluminum spoilers and lots of stickers haha. thanx for all the info guys im gunna call action asap and get a quote from them im thinkin 84mm pistons i want to say i have a 2.0 well i guess it would be a 2.025 but u get the idea thanx again

 

JUST TRY IT AND LET US KNOW....

 

I wouldn't recomend going .30 over on a stock sleeve. I don't even think Honda recomends it either.

**** it im gunna sleeve it i called action they can sleeve bore balance and blue print my block so u guys talked me into it. im gunna run 86mm pistons on darton sleeves 12.5:1 and a 55 shot any objections?

Im sure there are a few places on the west side, but over here on the east (spokane)I had my b16 block sleeved by precision balancing (509) 926-4832. We had them install 87mm darton sleeves into my b16.
