crower has the best stroker kits IMO,make that bad boy a 2.2 on stock bore or sleeve it and stroke it to 2.3 or 2.4 around there

re: Is there such a thing as a "best stroker kit" for b20VTEC? Ideas?
i am confused now
1-buy lw crank 85m *89m
or
2-stroker 85m *92m
or
3-stroker 85m *95m
or
4- stroker 85m *95m long rod option
and dose the longer connecting rod 5.512" will fit with the 92m stroke crank ?
note:
longer connecting rod 5.512" vs. the OEM length of 5.394" bring the rod stroke ratio to 1.52 for the higher rpm .
dose this high stroke will not be matching the high rpm that skunk2 pro2 needs?
need help

stick with 84mm....and the stock stroke it perfectly fine unless you are planning to do something out of the ordinary with a stroker setup...it's an awful lot of money for what you are getting.
if you are dead set on a stroker kit then spend the money on a Brian Crower or Crower kit.

re: Is there such a thing as a "best stroker kit" for b20VTEC? Ideas?
Hi
My opignon on this is that you must have to over size at 84.5 to perfect fit the new pistons.
They dont offer 84.25
More thin the sleeve is going to be, the more you gonna have to think about it when pulling hard.
If you dont plan to go Autocross. the car will be streetable, to go work. and make some race against some other cars, nothing as starting 0km and the first at 240... this is bad.
, 85mm bore will last if you take care...
stock 84mm sleeve, driven by an assl will also crack...
When tuning the motor. you must avoid hot tune. tune it AFR in the 12:1 not 13...
keeping the bore at 84mm will make a oil sucker engine... unless its not burning oil now...
the crank choice can also be done all depending on how hight you want the motor to rev... and how long you want it to last
Eagle. Crower or other... crank is a crank.
right now, by my experience with Crower, i would tell you to keep away from them. not cuz the crank is not good. Personaly i dont want to make buisness with them.
Dave have the Big Head and if you dont go with what he want in your built, he can just stop answer you. whatever what you already did started with them.
I bught 2 set of cams from them. and they never answer me back when it was the time to make my custom one. Dave did not want me to tune the motor on the 404.. he tols me to go with custom one. 'winners use custom grind'
I WANTED TO SEE the power from those 404.
OK THEN I WONT SEE ANY DIFF FROM CUSTOM ONE...
Take a look at your budjet
see what you want to do with the motor (Autocross. Race Only, Street/Strip...) and build it
I went with the biggest stroke (97mm), and its me that drive the gaz pedale...
My built ran all winter long. at IDLE for 20 min every morning and nite after work to go back home. I am over 20000km and that thing suck oil since 15000km
An other advice, get a real oil pump.
also if you dont take a vtec bloc to start the project, that mean you wont have Vtec oil jets under the piston.
If you use forged rods... they dont have the oil hole either...
have something done to the B20 base to install the vtec oil jets.
Find a shop that already know how to install those jets.
And for your rod size, you have to stay with the stock 137mm LS/B20 size, its the pistons pinn that will raise on the piston (closer to oil ring) to make it fit the new stroke.
I hope your able to understand my english
and that this help

whatever u do dont go 95mm crank for a daily driver, believe me i have a crower 95mm stroker crank motor built by Ericksracing and it cause problem from day one. ****'s only got like 100 miles on it, properly broken in on the dyno by Ericksracing, made good power if u ask me 290's, but never found a clutch kit to work with it and now either the wrist pin is fauck or piston to wall clearence is increased because its making a knocking noise in one of the cylinder. not saying this will happen to yours but it's some problems that people can encounter from going with a big crank on a b-series motor.

If you go read my tread, youll see that my bloc was built 3 time by the first howner. never made 1000km each time.
The bloc and crank was ready to trow away. i told the guy, let me inspect it, and if it still good, ill buy it.
the thing was very bad. line bore was 1 - 2 - 3 tow raising from the first to the last
Deck was also 3 tow off
it was so much machined, that i had to drill the oil pump and rmove the doll pinn.
same for the cover on the other side.
Just to tell you that, Its the way the motor will be built that gonna make it RELIABLE
or not

P.S. 12:1 CR is Lill low to get the power properly from those S2P2.
I would use them at 12.5:1 and up.
In order:
Type R
Spoon
and toda A,B
or my 4 best choice for daily driven motor. (more power@low-RPM)
:
S2P3
Toda C
and JUN III
are the choice for more pony's.

The +.137" long rod option is nice but a little pricey. Youll need the "long rod" and the correct compression height pistons to match...
As much as ive read about stock B20 sleeves, the most Id go is 84.5mm and I would say a prayer everynight, But ive never personally owned one so thats my 2 cents...

Id go with the 92mm crank and +.137 longer rods and matching pistons. This is what im doing for the #'s im looking for (240/170). You can prob do it on an 89 crank, but the 3mm will help alot.
Just be sure to check every single little thing as nothing inside your block is factory anymore.Use a good reputable machine shop. Search for Teamdiesels threads. He has a 92x85 I think.

it has nothing to do with your crank
point is the cylinders are already weak, without sleeving them your gonna have major cylinder walk especially after 5k
dont expect the thing to last too long without sleeving
