hey guys im building my mottor right now and have run into a prob. any one used the crower rods and there build. i have a d17a2. is teh crower rod shorter than the stock rod?my crower rods are all shorter an di wanted to know if that is how it is suppose 2 be..

 

What rods did you buy? (Part number)

 

I never measured, but if you bought D17 rods and the requisite aftermarket pistons it works just fine.
Crower lists the length of their rod on the website, you'd have to measure the stocker and just compare.

 

bioler when u installed ur rods u had to notch them right??? my builder installed them an dhe said they werent even hitting the sleeves. and i have the fi rods from crower only mak eone model if im correct

 

crower has all teh d17 rods height as 5.393 but isnt the stock rod height for a d17 - 5.511

Yea both d17a1 and d17a2 rod length is 5.511"

From crowers site they say 5.394 not 3.393 probably typo on your behalf

 

yeh my bad i ment 5.393 so that means all teh crower rods are made wrong correct???

 

You have to notch the block. The tops of the rod caps will hit the sides of the crank case if you dont. Post the part number of the rods you got.


you can see in there where material was removed for clearance

yes i know that what im saying is teh rods i have are shorter in height to my stock rods shouldnt they be teh same height? ithere at teh shop right now an di dont have them on hand

 

Just put the motor together. Only D17 rods fit a D17 crank journal. All of us are running wisecos on crowers, the motors make tons of power and dont break.

 

most of the time

The bottom ends dont break. They make SOOOOOOO much power that the headgasket cant hold it.

 

but if the crower rods are not the same height as my stock rods wouldn't that cause a problem?

 

if they're a hair shorter,what issue would it cause? The pistons need to be below the deck, which they will be. Worst comes to worse, the compression is a hair lower that what the pistons are stated to be. Stroke is dictated by the crank throw, and you need to tune it afterwards anyways.
Just put the damn thing together and stop thinking about it.
It doesnt really help that you're going off what a shop is telling you, and you havent told us where the measurements are being taken from.
You'd have a big problem if they were longer. But this does nothing to effect anything of consequence. If you're so worried.... do yourself a big favor, get off the message boards, pick up a phone and CALL CROWER

 

Shorter rods = less compression. If u are going to turbo then it should be fine. If it is an n/a build then u should use high compression pistons if they are available.

 

also i was weary because it dosent look like i have to notch teh sleeves for the crower rods. and almost everyone who installed them had 2 notch there sleeves...but couple people told me they have herd of no nothcing being needed. i just dont understand how some have to and some dont
