As title. Perfect crank.
1990 Nissan Pulsar GTi-R
1991 Nissan Pulsar GTi-R
Found a block. Now need a crank
anyone? I want to get this build rolling and this is the final peice of the puzzel. I have two cracked cranks right now.
Now own three cracked GTiR cranks....Someone send me a good one dammit!!!!
Can you post pictures, please? I want to see this; not that I don't believe you, just want to know what to look out for.
Yeah I'll get some pics up. I junked two of the cranks already. but they all cracked the same way and in nearly the same spots.
is it really a cracke or a mark made when they did the crank ....
post pictures please i'm really curius about this . !!
Might be worth a mag-flux leak test if you can get it done free or cheap.
Are stock cranks forged?
You could also grind the area to see if it is a machining mark, since you will likely have it balanced anyway.
If it is a machining mark we should see a couple for sale soon! lol
GTi-R, the best ugliest car I've EVER seen/driven. You can make it cool, you can make it fast but you CAN'T make it look pretty.
I doubt that anyone would recommend me grinding the crank journal surface unless they wanted me to completely destroy the crank.
here is a pic.
All three cranks were cracked here. This one was the least detectable, and one was even cracked on both sides of 2 rod journals and both sides of one main journal.
well if you had 3 like these, you would have been able to make yourself a nice table ..
i know what to look at , when i'll overhaul my engine ( if it hapen)
New crankshafts still price out at work. Not cheap though.
how much? can you get me the employee discount?
You can still have it fixed but you'd have to weigh the costs against a new one. Maybe you can get a volume discount now! lol.. sry .
Fixing the crank at the journal requires it to be first ground, then metal spray weld, then machining, heat T....blahblah, etc.
You're doing a complete engine build so maybe this is something you should consider...fully prep'd crank, knife edge, balanced, align-hone, etc...
ps; they are forged.
Not cheaper to fix than buy a new one. I doubt highly there is anyone in London that can do it either which means shipping and delays. Plus then you have a repaired crank. I'd rather buy a billet one for 1300ish and be done with it. Comes balanced knife edged and brand new.
But I'm not goig that extreme on the build. Sticking factory bottom end so there is no reason to get a crazy crank. I'd run the DET one but I spent the money on gtir bearings and getting gtir rods prepped and arp bolts installed. So I might as well have the crank surface to use the bearings.
Tech44 I'm serious about the new crank, what are you showing for a price?
NVM got one from my dealer. 1185, unknown shipping time. From Japan, none in NA.
This is what I found; 12200-54C05, crankshaft assembly. Retails at 1185.07 plus 12% HST. You could take that number to any local Nissan Dealer and see what they can do for you. Covers 08 month of 1990 to end of production.
1327....so better to buy a billet crankshaft.
anyone know of any ontario companies that specialize in welding cranks?
Crank That SR Boy
I’m mid-way through my project 240SX and ran into a problem. I decided to go SR20DET instead of KA-T because I found what I thought to be a good deal on an SR. I tore it down and found that my crank was pretty much done,a main bearing failure that somehow caused a crack on the 5th main journal. So much for a “built” SR. But my question is: will a crankshaft from a FWD SR work in a RWD SR? Sean Callahan Newark Valley, NY
A That is a good question. Since we have never encountered this before we asked a few SR20 gurus that we knew. When we have a SR20 issue we can’t solve, we ask Gary Narusawa (OMG) from Project Car Mag and Marcos Vargas from SR20Store, and this is what they said. The FWD and RWD SR20s are very similar in design and construction with minor differences. With the exception of the Pulsar GTi-R crank, you can use any of the FWD SR20 cranks, even the USDM NA one. Of course, when you do something like this, make sure your engine builder checks everything to be sure that it is compatible and will work with your “hybrid” build. If you need a good reliable source for parts and helpful information, contact Marcos Vargas at the SR20Store (sr20store.com); he is the ultimate SR20 guru.
Also, could you use a non-gtir crank and bearing? Just a thought.
Yes, but then the bearing would not centre properly in the rod. This is fixable by either getting a new bearing locater cut into the rod, ir by using non GTiR rods.
If I'm going to have to go to that trouble I'd rather spend the time and track down a real gtir crank and utelize the 2mm wider bearings. There is a reason they upgraded.
