Just finished putting it together and she runs! haven't had a chance to drive it yet Because it's so late. Gotta bleed the coolant and put the bumper back on before Work at 12 pm :D. she started up and idled nice. was pulling 40 ish vacuum. (is that good?). And either the engine wasn't warming up or the temp gauge doesn't work. Don't know. Updates tomorrow.

Some pics:

Looks good! The atmospheric bov may give you some trouble, but you should be able to recirc that one if you need to.

yea the open bov causes some problems but it's ok. going to recirc it eventually. The clutch is worrying me tho. when taking off in first there's a grinding sound, but shifting normally after that theres no grind. i'm hoping it's just cuz this clutch is crazy or something...i dunno

It's an ARC front mount that uses the stock piping route

I agree that 40-50ish hg of vacuum is totally abnormal for even a tightly built CA. I'll safely assume that you have either a bootleg boost/vacuum gauge or you just may be referring to the oil pressure. Crappy gauges will give you stupid readings.

It's certanly not a "bootleg" gauge. It's a blitz manual boost gauge. It reads 50 ish at idle and .5 boost at wot....or maybe it is a crappy gauge haha, i don't know

2 problems one big one little

Big problem

Something's up with this ORC single plate clutch and flywheel tho. The trans makes a horrible grinding when taking off,and sometimes when shifting. And when I give it a rev in neutral you can hear a slight grinding. My friend had a much worse case of this and it turned out he didn't tighten his flyhweel bolts .

Not so big problem

The car drives funny when you're at part throttle. Like when driving through the neighborhood accelerating slowly to 25 - 30 mph. It's seems that when the boost gauge is at 0 the car hesitate and acts weird, but when you open up the throttle and get into boost and 3000+ rpm it's smooth. any thoughts? Grounds maybe? I checked all the vacuum lines and the only thing abnormal is the "L" shaped fitting for the ventilation hose on the exhaust side valve cover can easily be taken out of the valve cover. Like it just pops out... I was like..."that can't be right" So I gooped it with some black rtv and stuck it in.

this sound exactly like the same issue I had when I had a bad Coil.

check your plugs and see if they are all working more than likely one will look brand new. I had to replace the 4th coil and the car now runs amazingly.

It's probably popping-off because you may have excessive blow-by. Do a compression test on your engine as well as run the codes and let us know what you find.

No way that motor is pulling more than ATM pressure. Your gauge is off.

About the 90 on the exhaust side valve cover, That happened to me a couple times. your probably just venting alot. Just keep an eye on it. Once mine fell out while driving. I had to go to the junkyard and get another one.

When you put the clutch in did u need to change the fork and bearing assembly?Did you change the pilot bushing? When my pilot bushing was goin bad, I had nasty noise taking off in first and reverse.

OK... The horrible grinding...The flyhweel was loose! If you're using an ORC SR20 clutch, or maybe any sr20 clutch I don't know. You need shorter bolts. My brand new Nissan bolts bottomed out and the flywheel felt tight because the flywheel was jammed on the pilot bearing protruding in the middle of the crank.(engine was from an automatic). So 4 broken flywheel bolts and all the threads ruined. we had to drill out the broken bolt and re-tapped all the holes to 7/16 x 20 threads per inch. Now I have to get machine bolts....very hard lesson learned.
