sup.. i am putting together fully built gsr turbo. A friend of mine was telling me that i need to change my crankshaft to make anything in the 400s. Is it true or no?? Can i use my stock crank?

 

Yes, its recommended you use your stock crank. Just send it to a reputable shop to get it micro polished and balanced.

 

ya use the stock one

 

do me a favor and slap your friend in the face for being a dumbass. stock crank is fine...i personally have made 550whp with one and people have made over 700whp with stock crank....

 

fixed that for ya

 

stock crank is the weakest part of the OEM engine, change it asap, buddyclub makes a stage 6 crank

 

The buddyclub stage 6 crank is only good up to 559WHP. Anything thereafter requires a OBXR titanium/aluminum stage 9 crank, I use one myself.

 

dont forget your obx2000 series rod bolts.

 

no its not necessary, a little hatch i know of that still has the stock crank dyno'd 754 wheel about a month ago.

 

710 on a stock gsr crank.
just make sureit is std/std not undersized.

 

I am pretty sure my crank has been turned, survived 9800rpm on a regular basis so far.....haha

 

I'm not trying to be an ******* so dont take it that way. But. If you would have done a little searching through Honda-Tech you would have found your answer easy. From 150whp to 850whp cars running OEM Honda cranks

 

i agree wtih alpha, b series honda oem crankshaft are rated around 800hp. You can keep it stock or get it micro polished and balanced. no need to change out the crankshaft, unless you have done damage such as rod bearings and there goes your crankshaft.

 

i have seen a oem crank run in the 8s i say keep the stock crank

 

Oh, i hate these "my friend said..." threads because most people have stupid friends. As everyone else has said, you'll be totally fine. Any other myths you'd like us to dispell while we're on the subject??

 

im using a stock crank for a power goal of 650+ whp

 

as am i.

stock will work just fine.

 

I was inches from reporting his last "my parts list" post, and this just reinforces the point - ITSJDM please read the entire FAQ thread, you clearly are lacking some important knowledge regarding turbocharging a Honda. They are nothing, I repeat NOTHING like the SRT-4 you had.


BTW anyone have a link to that french SRT-4 magazine vid? The one where the SRT-4 owner smokes his clutch trying to do a burnout???
