i have b18b with 87.2mm crank (gsr), a friend sell me 89mm CROWER crank which want is better for turbo?

 

there is alot more to this question than what crank is better for turbo. what is your set up and what are you trying to accomplish with a stroker crank.

 

25x8.7x13 mh, gsr tranny, motor rev 10,000 i want change this stroke by 89mm because is more strong crower crank

 

that is very small amount of info on your setup buddy... its not all about the crank...

 

I would trust a stock crank over a Crower crank any day as far as strength is concerned.

x3

 

X4

 

Motor rev to 10k eh? You got the mods to support those revs or are you just spinning it that high to just do it.
OEM crank will be the way to go, the only aftermarket crank i would trust would be a golden Eagle or Scat.

 

OEM GSR crank loves 11k rpm

 

OEM crank is the way to go.. listen to all these fellas, they havent gone 9's and 8's for no reason. ive learned alot in the past year just reading and researching on HT.. if your not looking to compete and sqeeze ever lil 1 hp or 1 tq out of the setup, its not worth your time to spend the money. a stock gsr will easily do 400-500 with the right tune. bigger isnt always better!

 

If your dead set on replacing the crank, micropolish a stock ls 89mm crank.

 

gt-4294 112 exhaust housing,skunk2 pro cams,edelbrok intake,75mm throtelbody,dalton sleeved,85mm piston, top mount BWR manifold,car ran 9.61 151mph.want opinions because we had problems with the engine and have the crower crank,the enguine makes power up to 10,400 rpm with the gsr crank,it made 750 whp 438 tq at 29 psi

 

I would suggest you push the envelope on your current setup first.if you're done with it and you think the needed power will be gained by changing the stroke then go for it.

 

 

we have made well into the 1100whp mark using a new crank from honda & adding some coating to it.

crower,eagle, etc will not hold up NOR balance out like a genuine honda crankshaft.

on a side note our engines make power into the 11k+rpm mark.

Rob-

using a crower,eagle crank is like having sex using a ballon for protection, it might get the job done, but its just not the same......

 

There is a 24.5"/9.0 e.t car that is consistent that runs a scat stroker crank and holds up. The BC stroker cranks seem to hold up pretty well. Had a eagle stroker crank crack at the main journal awhile back on the dyno, that was not a pretty sight. Different turbo/cam/stroke combinations work extremely well together, its just expensive experimenting.

 

 

thanks we found a std gsr crank and are going to keep the setup like it is,thanks for the advice
