Hi, I know this topic has been discussed to death, but at the same time there isn't an agreement even on older posts here - How reliable are the B20 sleeves on an N/A application, is the engine as a whole as reliable as a B16 on a close to stock setup?
Before you flame me, a quick story:
I have the original B16A on my EG6, but it's due for a rebuild and I have the opportunity to pick up a B20Z block for a good price. The problem is that B20 blocks are very rare around here, and if something goes wrong it will be quite hard to find a replacement, not to mention there's a lot of paperwork involved to register another block to the car. It will not see any boost, but my goal is reliability over power. The questions are:
- Does anyone have personal experience running those engines for YEARS without issue?
- Is it a time bomb as many say?
- What needs to be addressesd besides the usual ARP rod bolts and a meticulous assembly?
- Should I just forget it and rebuild my B16 because it's just a matter of time before the sleeves crack?
It's a street car as it's pretty stock down to the original fat five wheels, apart from some basic bolt ons and a suspension refresh. It will definitely be taken to the dragstrip and to the circuit, though. The goal is to reach 170whp with the stock B16 8200rpm rev limit and stock B16AX cams. I just want to enjoy the car and do the usual running maintenance. The setup is: Ported and sligthly milled B16 head with valve job, 3" short ram intake, DC JDM 4-1 2.5" header, stock 2" exhaust with no cat and freer flowing mufflers, ajustable cam gears, chipped P30. Not sure if that is enough for my goal, but it's what I have.
