I will just have you know that sleeving a block is not cheap so get atleast a complete quote first. I think mine was alittle less than $2k. But, it can be a block that lasts forever for multiple builds over time and can take almost any abuse especially all motor. The head is more likely to fail. A plus is that Darton leaves the deck of the cylinder walls 0.002'-0.005" (I used 0.002") taller for extra head gasket insurance. Imo its not necessary for the na but can be a confident long term block with no mechanical worries, as long as a blown tune doesnt gash walls. Still need other internals for high compression nitrous too.So I was coming upon the last stuff needed to get my high comp beast on the road. Hit a snag, got some rot in cylinder one and some bad pitting. Boreover might work, but I just got a killer deal from Darton to re-sleeve the block
It feels like overkill to sleeve a na block but still, maybe raise compression to 12.5:1 on forged pistons? Add a hundred shot of nitrous?
That would be a wild ride to have. DId I miss a build thread?Daily, I car pool, and live close enough to ride my bicycle to work, have a 12 Altima (for the misses) and this will be a run and gun special. Once it's done, I'll be picking up a z for twin turbo build, and this will remain daily. Eventually it'll go to hpde, but will stay in full street mode, maybe a light cage, but will remain all motor. (I don't mind is being ricey, loud, or no power through the city just cruising, it's part of the charm of the engine set up.)
Currently has 11.5:1 compression, I have a full ported and polished head, fully rebuilt with rz cams, springs, ti retainers, and fresh valves, ready to be bolted in, and have a hedman full race header, 3" stromung exhaust.
