it is, but like any other stroker, it needs machining...comes with the territory

again, you need to ask your machinist what all is involved and what he will charge

Block needs to be cleared in several places, and you will also need a billet girdle which will also need some modification. It really comes with the territory, when putting a stroker in a VQ35.

Sharif, for a FI build I agree with you 100%. However, for a naturally aspirated stroker build notching the stock girdle will be adequate.

The OEM girdle is fairly thin in places, and it worries me to carve away too much of it. You are correct it can be done with OEM.

Edit: What worries me more, and is kinda creepy...is we are posting in Julians thread from 2007.

That is why they introduced the slightly smaller stroke one - because it needs alot less machining (retains squirters), and will yield virutally identical power for all intents and purposes.

There never were issues with it...the issue is on the part of an installer who may be ill experienced for this type of build in the first place. A stroker is shoving 10 lbs of dung into a 5 lbs bag. Some guys know how to do this, others don't. You gotta find the machinist who knows how. The larger stroke crank will simply require alot more machine work and eliminates the factory oil squirters - which again can be compensated for in any number of ways by someone who knows what they are doing in the first place.
The 86.4 crank still does not retain the squirters....just for clarification.
On Rich's engine we were able to modify the pistons and couple other changes to retain the squirters but it was not easy.

Thanks for the insights, Sorry if this is a bad thread to dredge up, I searched for BC 88mm crank and this seemed the best place to ask.

How much would you guess preparing the oem gordle? Would I be better off getting this?

Where is the part number hidden on the crank/box? I have nothing but this:

The label just has the specs.

guess: 026A88=26th 88mm crank and 0702005 (7th month of 2005)=crank design date (not manufacture date)

call and ask

I sent them an email with the picture.

Figured it could not hurt to ask. I am sure someone knows.

The date was my guess as well as the 88mm, but there are balanced and unbalanced versions of all part numbers and there has to be a way to tell based on something on the crank.

Thanks

thats the balance one.

The unbalanced has a U stamped at the end of the crank

Regardless, your machine shop should always check it anyhow

My luck improves!

Uh oh!

I intend to have the entire rotating assembly balanced.

You have no choice but to balance the whole thing

How well its balanced and to what rpm I have no idea you have to ask them.

I hope you realize what you stepped into and that it comes to fruition - it ain't going to be cheap or any adjective remotely close to cheap. As everyone has suggested you need to find a good machinist to do this who is used to doing builds of this level and guide you through your next steps and purchases.

I guess it works out I intended to.

:P

But that makes me wonder why buy the balanced unit when it has to be balanced as a rotating assy?

Is there "less" balancing with a balanced crank?
