H23 Plenum bored out to 70mm...
Skunk2 70mm TB
S2 eating the stock TB...
S2 gasket on stock TB...
Partially assembled H23 IM vs stock (and very dirty) F23 IM
[WARNING: THIS GETS GHETTO]
Here is my 'solution' to the issue of water pipe fitment. I have both F23 and H23 water pipes, and compared them side by side. The H23 water pipe won't work because the water pump side is much larger than the F23's. I was going to join the bottom half of the F23 with the top of the H23's, but figured it would be just as easy to use the complete F23 pipe, only to split it in two and give it some flex to let it fit better. So there it is...
Here is my jewel. All the fuel rails I've seen place the fuel input on the passenger side when mounted to the H23 IM correctly. This H22A fuel rail matches the H23's posts exactly, and keeps the fuel input on the driver's side so you don't have to extend the fuel line. (I hate modifying sensitive parts like high pressure lines)

2 things:
first, 70mm is ****in huge
second, that nut that is on the fuel rail in the last pics was the nut i was describing. please tell me that will work cause i still refuse to believe in different pitches on the rail thread

Yes, 70mm is effing huge. It should flow tons more air than I'll ever need on this car, but should give a nice throttle response.
That nut on the fuel rail was the original one that came with it when I bought it. I had pulled it off to clean the rail, and forgotten that it existed until I found it yesterday. I'm PRAYING that it seals and doesn't leak when I get it on there and pump fuel through it. The pitch is in fact different, if only slightly, because the FPD and cap are not interchangeable on the fuel rails.

Yep. Got all the vacuum, coolant, and electrical connections made tonight. Gotta adjust the valves and install the alt and PS pump tomorrow, and it should be good to go. I primed the fuel pump a few times tonight and no leaks so far, and tested the TPS which works nicely. It's just kinda weird barely pressing the pedal and getting ~50% throttle.

Had to grind the bracket off the fuel line's banjo bolt to fit the JDM H22 fuel rail.

do you see why i did not do a write up? too many little parts that no one can remember
congrats, test drive her now
