I am currently running a stock JDM B16A3 & am going to be swapping the IM, TB, & head to a JDM ITR set up with Portflow titanium retainers, Portflow stiffened inner valve springs, ITR intake outer valve springs all the way around, & CTR cams. Probably a bit over built for how I intend on driving. Trying to keep the rpm's around 8700 to 9000 tops! I'm also looking to increase my compression to around 11.1:1 by using a single layer of an OEM head gasket. I'm keeping the block stock with the OEM bore and need to know which OEM gasket to use & which layer is best if any. I figured copper spraying would give me a little more insurance against any leakage. How safe is this? I've been seeing a few people running single layer gaskets & want to know your guy's opinion. I'm not trying to get any outrageous hp/tq #'s,nor do I want to have to tear everything apart/rebuild every 10K, just want a smooth running, reliable, FUN daily driver that's capable of busting a little ass every now and then. I plan on getting a chipped/basemapped ECU to start things in the right direction & have tuned later on. I also need to know what fuel pressure, fuel pump, & injector size would be best for this set up or if the OEM stuff will be sufficient. Zealautowerks.com has an option for a single layer .009" thickness according to them it's still in the acceptable range. If there is anything else that should accompany these intended mods, please let me know what you think. I've seen a lot of posts from some of you with a great deal of knowledge & would appreciate any info you may have to help make my build successful and most of all reliable.
