^Couldn’t agree more on the pan gaskets. I think 90% of the pans I’ve ever encountered (that weren’t on their first gasket) had the rail warped from overtightening.

I thought everyone used the felpro metal gasket by now. I honestly cant remember when i bought it but at least 5 years ago and its still leak free. No rtv needed at all.

Hopefully there arent any high g right hand turns.

That wastegate placement might be good for a lap or two. Id rather have a half size radiator than a radiator getting direct heat onto it.

That drain has me alittle nervous.

For the injectors, i recall Injector dynamics stating to use 92-95 civic orings. I reused the 92-95 orings that i ordered years ago. They also seemed to fit really good into the victor x manifold that i just bought from gen2ls

Limerock is clockwise lol. Its almost all right hand turns...

Maybe. My half rad never seemed enough to do the job long ago.

NA, with a 145° thermostat, the motors in there before had a hard time getting 170 after 15 minutes in 90° ambient heat with this radiator/hoodvent combo.

The wastegate is watercooled, for what its worth. I think itll be fine tho.

Instead of fiberglass wraps this time I want to try the crinkley heat shield I see more track cars use in person. I have 2 rolls standing by for the time to install it.

The K coils are ridiculous tall in the non-V cover. The Honda Rulez/Burton coil plate makes it way better but it’s ill thought out and took some work and a couple of trips to McMaster and the ARP store before I was happy with it.

It looks like he safety wired them down. Thats probably a better solution. I havent measured but locash says that they sit too high on a bseries cover and dont touch the tip of the plugs completely. Ive never had an issue with mine… or maybe i do and dont know?? 🤔

Never been an issue on mine, aside from being a bit silly looking.

Im trying to run the r35 coils eventually. Ill end up making a plate I bet. I can do some cad and use send cut send if anything. But the plate looks good, basically that.

So yesterday was fun.

So first I cranked the motor with no plugs and injectors disconnected until I got oil pressure. Cranked for 10 seconds, didnt see pressure. Looked for leaks and had one. The oil cooler sandwich plate wasnt seated. I had to shave the 1/8 in npt block off in one of the ports in order to get it to fit on the block and apparently i didn't shave enough. So i cut it basically flush. Reseated that mess (tight spot). Cranked another 10sec. Got pressure. No leaks. Put everything back to fire it, and I get a cam home trigger error. Well, it was hard to feeler gauge that out. So this time I used the haltech oscilloscope to view the signal. Adjusted the sensor a slight turn out, retested. Repeat till i got a good signal. It fired up, kinda ran like crap and real rich. I cut it. Look for leaks, yeah big puddle. From the turbosmart oil pressure regulator. I forgot all about the drain back for it.

Well no worries knew how to route it. Rear freeze plug. Poached a fitting from the itb motor. But there was one problem, no more -4orb unicorn fittings in my pile or at any near my supplier. I had to drive to lane automotive 1hr away in Michigan to get the $10 fitting foreshadowed in the earlier posts. Lol. Literally. I already had a -4an to 1/4in hosebarb adapter... So i booked back to town and hit menards again for a 1/4 to 1/2 in barb setup. Those in hand, ran to autozone and grabbed a spectre filter. Back home, plumbed up, friends stopped over and we did another test start. This time better, no major leaks right away. Still sounded like crap tho.

Found some loose an fittings on the sandwich plate that must have gotten disturbed in the prior repair. Then found a coolant (water) leak at the outlet of the turbo. The harbor hoseclamp was slightly knurled in wrong and cut into the silicone hose. I got soaked fixing that one. First oil all down my arm into my armpit from the sandwich plate then drenched in water. I remember how much I love turbos 😜

Back to running the motor it was apparent the map sensor calibration was off. I verified the specs for the omni 4bar. It would not read 1000mbar koef. So I fudged the numbers and made it 1000mbar. Well when it ran next i noticed it said 500mbar and throttle change did not cause a change to mbar. So back to amazon that goes, doa $120 sensor. So i put an oem denso on it. Used the haltech calibration file, fired right up and sounded correct. Now running for more than a few seconds, found the cam seals were wrong. Not sure how I missed that. Vtec ones too small. Pulled the vc off and used some harbor-orings that were thicker to make up the slack. Took a min to reassemble but once done, tried starting and had home signal errors again. Readjusted the sensor as before and started again and no leaks. So thats probably a thing if you remove and reseal the vc with a cam sensor in it. Maybe. Maybe it wasnt super goldilocks at first. Anyway. Got to bleed the coolant then, rev it a few times, listen to the wooshy wooshy. Sounds awesome. Surprised how loud it still is. Love it!!

Then we installed the wing. Quick and easy thanks to the help of my friends. Perfect!

That capped the night around 10pm. I had to clean up and get stuff together to leave so i just cleaned up and went to bed.

Today I woke up, did a couple test drives to meijer and parents house. Their neighborhood needs paved, pretty bumpy. Exhaust passes the rumble road test. Got gas in the jugs, food for me and cats, hauled home in style. Car runs good. Quicktune doin some work it was rich in some areas. Timing felt right. No bogs or hiccups or goofy stuff. Sounds crisp but not too crisp, if you know what I mean.

Trailered up and on the road. Better pics soon. Dyno tomorrow, James and Ben are waiting for me. Lol.

Pics!

So happy to see it on the trailer and on its way to CT! All that thrashing paid off. It looks sick and I can't wait to hear about how it performs.
