No its an sr20, the main caps are separate.

 

no then your fine aslong as your not changing a main cap otherwise you'll need a line bore

 

Nope, using the factory main caps for that block. But Im using ACL race bearings.

Would the ACLs need a line hone? Glenn said they do, but I do not know.

 

A line hone is just going to make the clearance larger, so you'll need oversized bearings.

OT: Realised my miss/hiccup is ignition related.

 

Shouldnt unless you had damaged to the cap or block.. If there is no scaring or anything you should be able to just get bearings.. Line hone does make it bigger.. the reason why one would usually want to line hone something would be because of damage to a cap or the block or you changed out a cap and you need to make it true again.. So to answer your question, no you shouldnt have to get a line hone unless there is damage to it or a cap has been swapped out.

 

The only reason you'd need a line hone is to correct a block straightness issue, which would affect any bearing you put in there.

What do you guys think about the possibility that the crank is bent, throwing off tolerances?

 

One of my friends is interested in the old lip if you still have it.

 

i do. its pretty beat, but not cracked i dont think.
let me get a second look at it and figure out what its worth.

 

found this on my computer this morning, forgot i had it. neat.

 

Its always possible.. At the same time it would probably show wear on the mains bearings.. If the block was eating up main bearings then deffinatly should get the whole setup checked out..
