Crank Scrapers for the KA
 

Whats up guy's did a little bit of research on a crank scraper, wanted to know from other people's first hand experience if it works well. It happens that Kevin Johnson replied to my thread (the owner of crank-scrapers) he led me to the indepth info that I needed. Pretty much a crank scraper breaks down the windage loss proccess allow's the crank to move in rotation a little bit smoother and faster. For $50 dollars it is agreed to be a worthy investment.

so pretty much these crank-scrapers are just a sort of gasket? have you installed one of these?if so, any noticable gains? like I said before, i was thinking of puttin in those S13 cams and thought that if this mod was really worth it, since i was going to tear down the top end a little.. is there a whole lot involved to this mod? Just curious.. like i said, i'm still a noob, but if i try anything on this new motor, i have a friend who is an actual mechanic that actually knows the parts to a car to help me. it's all a learning process for me. if it's worth it, i'll mention it to him and maybe try it out

see... i'm tryin to learn a little.. i figure the best way to get to know my motor is to actually get in there. i'm actually thinking about completely tearing down my blown motor after I pull it just to really get down and dirty w/ it all... maybe try and part it out.?do you think it would be a good idea? or should I just leave it alone?

Let me break it down like this....
As RPM's raise in the crank case of the engine there is turbulance and windage that is created, that actually makes you lose HP. A crank scraper breaks and stops the windage process so that the crank can gain RPM's more efficiently, so technicaly, the engine is gaining HP as RPM's raise with a crank scraper.
For 50 bucks to gain HP I find it to be a good deal.....

looks like it would just stop the oil from splashing and prevent the windage... for the price, i'd try it... or go knife-edged crank and solve the problem that way :)

For $50 I'm going to do this mod after christmas.
People have claimed nothing but good results with the crank scrapers. I wonder how much rev would increase with the scraper and a knife edged crank, guess someones going to have to find out.

pretty sexy! so its somewhat like a baffled oil pan =0P ?

Some what. It's like half of the baffled pan. You actually need a baffled pan. I spoke with the owner of crank scrapers and he said that there are a few in the works for the Z/kae/kade.
The scrapers still work without the baffle, there has been noted improvement in acceleration and high end power just with the scraper.

ok dont get me wrong BIG V.
I do respect your knowledge quest for the
ultimate N/A 240sx but
Man, Maybe its just me but the
"crankscraper" sounds like the most useless mod I have ever heard of.
I meen dont get me wrong i'm not hate'n
or any thing" to each his own" I always say but for the turbulance I thought this is what the dampner on the crank pulley was for. sorry just my 2 and a half cents.
nothing against you find BIG V. Its just my opinion. much love dog!!!!!

^^^^ Double posted.......
It may sound useless to you.
I thought it was too at some point in my life.........
I guess people that own a scraper really says it works.
If scrapers didn't work they wouldn't come standard in most porche engines......LOL

cool . it was just my 2 cents or maybe just 1 cent LOL.
oh and i dont know why the hell it posted
twice thats ****'d up

Hi,

This thread popped up on my referrer logs...

Crank scrapers are pretty common but they come in different styles so you may not recognize them. Nissan uses them in many of their engines. Here is a pic of a crank scraper louver in the SR20:

Hey Kevin

Will I need additional gaskets for the KA24de scraper?
Or can I just use the scraper for the DE as a gasket?
I'm a bit confused with the design.

You are correct: you use the scraper as a gasket with RTV on both sides. I can email you the instructions if you are interested?

Shure.
