stroker kit anyone?

[whoneedsvtec]

i've been doing some research on the crower stoker kit for the B18B1. it sounds like a good choice but i dont know how it will react to being turbo'd. i know i can get the compression ratio at 9:1 like i need it but i still dont know how it will react. will i have increased detonation? leakdown? knock? plus will the longer rods decrease the strength of the rods? with a stroker kit and turbo i know i could probably make a huge amount of power. i just want to know if anyone has done anything similar and had any problems.

it would increase side thrust and probably hurt reliablity alittle but with the new rods i wouldnt think the longer length would be an issue. it wouldnt rev as well but with a turbo that would be a torque monster of an I4.

Be prepared to buy ultra-premium fuel and octane boost if you ever go forced induction.

[Kill4A911]

whoneedsvtec, just out of curiosity can you get 93 octane in FL or just 91?

[Gerbilo]

you would really need 93 for that? i figured 89 might cut it, but i don't know too much about what he is doin.

[Kill4A911]

oh no i wasnt saying he would need it just for the stroking i was just wondering, i know in some places all you can get is 91. but for turbocharging yea definitely premium (i use it any way its worth it for the difference in performance)

Dude, higher octane doesn't increase performance. In your engine, it burns too slow, some Hondas actually show a decrease in horsepower with higher octane fuel rather than the reccomended 87/89.

A 2000 Accord V6 actually shows something like a 10 hp decrease with 93 over 89.

[Kill4A911]

yea if your running low compression N/A, he's talking stroking and turbocharging

[911GT2]

Yeah and you said you use premium anyways for the performance gains.

There are no performance gains.

Interesting, because the Honda Odessey is noted for having a 10hp GAIN in performance when used with 91/93 octain gas, instead of 87. Seeing those use similar engines (the Odessey being based off the Accord) I don't believe that to be true about the Accord V6 having a DECREASE of performance. The 10hp gain was actually something stated in the manual for Odessey's at least back a couple years ago. The difference between 205hp and 215hp there.

You are right that when used in a stock or mostly stock performing car, premium gas doesn't do anything more than waste your $$$ away into exhaust smoke. In a stroked/FI situation you NEED higher octain for the purpose of increased compression in the engine.

[Gerbilo]

yeah, i never thought it would help unless your car needed it...

in high compression cases with low octane. detonation occurs before the spark lights it up, decreases performance, hey, we aren't runnin diesel here!

[whoneedsvtec]

the turbo kit actually comes with detonation protection that retards the timing .5 degrees for every pound of boost you're running. so no matter what rpm, or fuel rating you're at it doesn't matter. no detonation.

[whoneedsvtec]

yeah, you can get 93 octane in florida, it just costs a whole sh*t load of money.

If I remember correctly, the Odyssey reccomends premium while the Accord does not. And the engine isn't based off the Accord either, it's the MDX/Pilot engine that was new in the Odyssey.

Still not foolproof. And you DO realize that retarding the timing will make you lose power, right?
