My sr had a piston meltdown in #3 cyl.
Now I have to decide on if the damage is too great for a light hone.
I now know that there is the nikasil on the walls. Something I did not know until tonight.
With the cost of a Diamond hone (if it will work) or sleaving the cyl wall, is it better for me to just find a new block.
Any advice from people who have experience rebuilding an sr or a good knowledge of it, would be greatly appreciated.
Thanks
Dave
P.S. Anyone have a good block for sale???:)
Please advise.....Should I just find new block??

Darton is the best place to do the sleeves. Of course you can get HKS for like 500 a piece:eek: Or go to a local race car shop and talk to them.
Either way it gets pricey, and if your not building a high HP car, you'd be better off selling that block as scrap to someone, and getting a block that you can either hone or get by on.
Are you sure you have no crank or rod damage?
I have a block that i picked up for $200, but im not sure if i want to get rid of it..you might be able to find one cheaper anyway.
If you can contact me off board i might be able to help you, but i cant list all my sources on the board or they will get depleated!!! : )

I have never worked on an sr,but I have worked around some pretty serious engines at the machine shop I used to work at.As far as a diamond hone job goes it should not be any more expensive,actually the diamonds leave a really rough finish and they last forever so we would use them alot for small boring like .010 and .020 over and finish with a 520 stone wcich is what I would do if it was just scuffed up and no chunks are missing where the skirt will be affected.
I've actually had a block resleeved after I cracked a cylinder. This was not an SR but a GM 231 (3.8) V6 block from a Grand National. Those blocks are everywhere but it was easier to just resleeve what I already had. The problem with buying a block is first you have to find one. Then, if your doing things right you're going to want to take it to the machine shop and have it dipped in the chemical vat to clean it and then have it magnafluxed to very integrity (no cracks). This block prep could run $50-80 or so on top of the price you pay for the block. I would just weigh your options here. Find the price for a new sleeve for an SR20 and check with the local machine shop for resleeving cost. Compare that to the hassel of finding another block, price of another block, and prep'ing it.
Yes...exactly. But, then again, Jesse may have one or a source for one.~Brendan777aaron wrote:Also,people usally don't just get rid of blocks because there is nothing wrong with them,especially one that has been imported from another country.So chances are that if you buy one that it too will have something wrong with it.
Well heres the latest....
Ive done alot of homework this past week, and heard all kinds of different options from sleeving, to new block, to sleeved race block.
But Rob at Enjuku has told me thathe sr block can be punched out .020 over with no problem, hes seen it done.
So tommorow Im gonna take the rest of the motor apart and have the block looked at htis week to determine if the wall could be honed to the right spec.
Or to see if the cyl is shot.
Stay tunned.
