Ok, so after much debate, and realizing a swap is too much money and time, I am just going to go KAET. The engine need a rebuild anyways, it's in surprisingly good shape after 200k miles, but it needs. I figure I might as well spend the money now and get it rebuilt with forged 8.5:1 s and Eagle rods or something. I havn't had the engine looked at yet, so I dont know how much over I will need the pistons, more than likely just 20 over though. Thanks in advance.

eh, oki, i found the 9:1s. I missed them, but they just say for KA24.

Plus is 9:1 low enough to handle say...25psi? That would be tops i'de say for bet-my-house-on-drag-day or something.

9.0/1 will work as long as you have a decent fuel system to support the boost you want to run. There's always alcohol for the bet your house days.

hah yeah. i've changed my mind yet again, as i do every 5 minutes about everything. For the next couple days I have decided on getting it rebuilt and running 10.5:1 and keeping it NA, making a custom CAI possibly, getting a 3 angle (I was told 5 angle may not be possible, they need to look at it) valve job. Already has the 2.5" exhaust setup. Also mill down the head a bit, but I keep trying to get people to inform me on how much milling will up the CR. There are threads on that in the 240sx Technical and Nissan Online Mechanic. Or just reply here if anyone cares to tell me. I am just mainly wondering if 1/1000 will be enough to get the benifits of the smooth surface, or if i have to go 7/1000 or something due to a uh..warped spot or something (i dont even know if this is possible) will that be upping me to 11:1 or something? And from what I hear 11:1 can pretty much only run 93+
