    With all of this, I am also going to get the ECU tuned, and I am wondering whether it is worth spending money on a Hondata ECU? if so, which one?
    I've got a 19 row oil cooler with -10AN lines, it's a Mocal not mishimoto but same dimensions. It is mounted in front of the radiator passenger side where the power steering cooler was (P/S removed). This is in a dc2 with standard full size radiator, there is plenty of room with A/C removed. You may need to experiment in the ej8. Also make sure if you are buying a kit that the lines are long enough to reach, dummy fit and trace where you want to route the lines before you buy.

    It makes a difference if you are tracking the car, otherwise I don't think on the street you will need it. If I don't cover the cooler in normal street driving the oil temp won't get above 80deg C and I am still using the stock water/oil heat exchanger where the oil filter normally mounts. On the track temps are usually between 110-120deg C measured at the oil pan for 5-10 laps depending on ambient temps.

    Thank you very much for the wisdom. At the moment I dont quite know where my plans for this car will end. I am definitely going to track it a bit in the future. The only real reason I was thinking of getting an oil cooler is because of the fact that I dont really know what I want to do with the car, so I am asking all of these questions to help with my future decisions.

    Also, is the engine you have N/A, or forced induction, and what internal parts have you changed, if any?

    Mine is b18c2, pretty stock just oem rebuild with higher comp Pistons and b18c7 cams. Running about 11.1-11.5 comp (based off online calculators which seem to vary a bit, I didn't cc the chambers and Pistons).

    An oil cooler is good insurance, make sure you get some gauges for pressure and temp so you can see what they're actually doing. Your oil pressure may drop slightly but as long as it's above minimum at idle it should be fine, at higher revs you should have well above minimum requirements. Some people shim the oil pump relief spring to increase pressure to compensate, I found I didn't need to.

    Looking at that kit it comes with ~4ft hoses, I would think you will need longer than that depending on which way you route them. They need to reach from the back of the block all the way to in front of the radiator.

    Another point I'd like to add is, are you thinking of getting something like a Hondata to tune these mods once purchased?

    Will give excellent increases all round and improve the overall power band greatly.

    Food for thought you know.

    Yeah I asked it in the OP I think, if not I am definitely planning on tuning and upgrading the ECU after I go through the fuel delivery.

    Yep, awesome. I am probably just going to upgrade to a set of Mugen steel/alloy/whatever-metal head gaskets, which apparently help with compression. I dont plan on doing any internal mods, so you feedback applies directly to my scenario. So thank you very much.

    Op has been updated with some Fuel delivery stuff.

    Remember the B18C1 is the USDM version of the B18C2.

    Hey mate, just re-read through your O.P.

    Seems like you have a decent idea of a few areas to look into, I would think about what order and what benefit each of the things you are listing would give you.

    My opinion:

    Intake Manifold - both the skunk2 and Blox V3 are pretty much the same design single run like the stock type r manifold. The stock dual stage manifold is pretty decent for a stock/daily drive setup, it is designed to improve low/midrange torque to give more linear delivery, not so much just for fuel economy. If you bolt a single stage aftermarket manifold up to a stock engine you wont see any real gains until you get it tuned. You may feel more of a power surge when vtec engages, but you will lose the low/midrange that the dual stage manifold gives you. What the single stage manifolds are good for is top end power gains.

    Headers - If you have the JDM 4-1 style these are pretty good. There are a handfull of kw to be gained in swapping them to aftermarket depending on which ones you get, but I would be expecting anything massive. There are plenty of dyno comparisons (look on Honda Tech) between all the aftermarket headers to help you choose. Another good thing about the stock JDM type r headers is ground clearance, most of the aftermarket ones will hang lower, if your car is low then inevitably you will scrape/crack your shiny new aftermarket headers on the first speed bump.

    Fuel delivery - prob don't need to change anything unless you have a problem now (do you have any surging/misfiring that needs correcting?). You won't gain any power as such unless you are maxing out your current injector duty cycle (which I highly doubt). I would do whatever hardware mods you are planning coupled with a tunable ECU, if you find you are maxing out duty cycle then look at an upgrade. FYI the aftermarket fuel rails don't give you anything except engine bay bling and a lighter wallet.

    Spoon leads/plugs - again only good for bling and bragging rights. $500 for ignition leads is pretty steep to me given you wont see any gain whatsoever from using them. Spark plugs I would just get some good NGK or Denso to suit. Stick with the stock heat range unless you find an issue, higher heat range can just foul up if they don't operate in the correct temperature range.

    Not trying to dissuade you from going through with the mods, above is just what I would do and have done for a similar setup to you. Hopefully some of the above is helpful, good luck!

    Dont worry about dissuading or anything like that: This is my first car, and I want to make sure I do everything right.

    I am beginning to think that I might just do the Intake manifold, Throttle Body, and ECU, as well as the Oil Cooler. I am starting to feel that I should keep the car as "Honda" as possible, with a few things to just spice it up. In the end I might just see if I can get the Intake manifold ported if possible.

    About the Headers: The car as it is, is literally just legal in terms of height, and the previous owner told me about the headers and why he chose them, but later I might see if I can get a custom Manifold made up to increase power, and stay tucked away.

    You, my friend, have possibly just saved me a lot of money, hassle, and wasted mods. Thank you very much. There are really only a few more things I need to know, and I will be ready to start getting to it. You have answered so much, and I really do appreciate it. 10/10.
