It was my own formulation of thought, and I could be way off here, that since the air is being forced in through the intake ports that the intake ports weren't as important to smooth and focus on as the exhaust ports. Since the exhaust gases don't have as much pressure being forced out as the intake gases have going in to the combustion chamber. Again, I could be way off here and more of a rambling thought I guess...thoughts and guesses gathered I suppose during the numerous hours of grinding
I wish I could tell you something useful but I have never ported a head. I'm sure someone smarter than me could chime in on the subject.

But as a jeweler, I appreciate how clean that looks as a first effort

You can get quality H-beams w/ ARP hardware for just over 300.

Also, what are you doing for a wastegate?
I will have to look into a few different choices for rods/pistons when I do my next motor. As far as a wastegate goes, it has an internal wastegate just the actuator isn't attached to the turbo right now. I am in the middle of making a bracket for it.

Lookin Good cwall! Let me know if your gonna be around any point friday, I forgot to take that radiator, and I have to get tires from your pops... The thing was right in front of me, but I think the cold makes my brain function less than it already does! I work crazy hours, but whenever you need help, i'll be another on that list!

Thanks! And thanks for the offer of another set of hands. Yea I'll be around Friday. Like I said, radiator was in rough shape but no leaks and it's never been installed. I'm hoping that by then I can have this thing running (fingers crossed).

I ended up getting my wastegate installed. I made up a mounting plate for that and put in a bung for the signal. Also got the intercooler piping finalized and clamped down. Also got in my new wideband sensor. Got that calibrated and installed. I am just waiting on my oil return line to get here and I need a fitting for my feed line as far as parts go.

But after it's running I still need to finish the install on my gauges, get some tires, and it needs a top too. Among other things. Details.

Very nice build! That headwork looks pretty nice, almost inspires me to mess with mine while i have it out this spring. Sweet looking valve cover, at first glance at the pics it just looks silver but looking at the dipstick reflection that thing is killer!

oh and needs moar test pipe

Thanks! Yea that valve cover had a mirror finish when I was done giving it a good polish. Right now it is pretty dirty from sitting in the garage with no hood and fingerprints and whatnot though.

haha gotcha

don't you just hate it when you order the wrong parts?

Today I get home from a wayyy too long of a work week to be overjoyed to see that the oil drain kit that I ordered was on the kitchen table! So I rip open the package, and see that the parts are EXACTLY what I want! I take them out to the garage and get busy. I put the adapter plate on the turbo with the nice 10 AN fittings that I just got. I then proceeded to attach the 10 AN 45 degree fitting to my oil pan bulkhead fitting. Now in retrospect, I should have double and triple checked what size the bulkhead fitting was. But I SWORE that it was a 10 AN. I had put this fitting into the pan a few months back but again, I was sure of myself so no reason to check. Well apparently it was an 8 AN fitting that I put in. And I now have this really nice 10 AN 45 degree fitting that doesn't fit. Fantastic haha stymied!

So I gotta say, Matt (taxicabyellow) ended up stopping by tonight to pick up a few parts (of which he did not bring any of them home) and he was able to convince me to rig up a silicone hose with some clamps as my temporary drain hose. So we got that rigged up, put on an upper radiator hose and we were in business!

So we fill it with fluids, and crank the motor over to build pressure and after what seemed like forever the motor built some pressure. We cranked it over, and sure enough, fired up on the first try! Woot!

I have my share of problems ahead of me but tonight was huge and Matt was a huge help. Thanks again! I got a lot to do, but tonight was a big step in the right direction. Back at it tomorrow!

So over the past week I've been making a lot of tweaks, fixes, and adjustments and it is running a lot better than it was last week. Got my idle down from 1500 to about 900, Got an exhaust leak taken care of, there was a major boost leak due to a missed vacuum connection, I replaced my return line with the proper stainless braided line, I got a new top on her, dialed in my BOV, installed some speakers and a radio, and did some initial tuning with Matt's help. Seems like everyday it is getting closer to running properly!

I have been going through and fixing a few of my mistakes. Today I was able to replace the front main seal. I had a little bit of an oil leak from the front of the motor, but luckily with the exposed cams I didn't have to take off the valve cover and it took no time at all! I also got my oil return line in, it is a little bit long though and I will need to go back and trim it down some unfortunately. There is a little bit of a bend in the line. I also was getting a little bit of a noise from the rear end of the car. I looked up underneath the car and saw that the exhaust was hitting against my rear def bracket! Problem there was simple, with the dual exhaust one side was hanging down a little lower than the other side. I pulled the lower side up to where it was supposed to be and hung it properly and it no longer hits, but unfortunately it didn't solve my problem of there being a noise. After further inspection I saw that it was a tire balancing weight hitting against my brake line, a minor adjustment, and noise was gone.

For the work on the interior, it needs a lot of attention. It is, well, it's dirty. It needs a thorough cleaning. But before I do that, I was able to get my radio installed. Nothing special, an Alpine deck with 6.5" Infinity's. The steering wheel is a Momo that I got when I was in high school. I had it on my last car for a few years and I loved it, so when I sold my last car I had to take it out. I was able to get a new top on it with the help of a few friends and it came out pretty well. It is really tight on there, don't think that I will be taking it down until spring time!

It needs a lot of attention and there are some things that I have rushed for the sake of time. I am on a little bit of a time crunch. I leave for school this Saturday and I want to get it running and mostly put together before I go back. There are a few things that will be addressed, like how I only have a cone for an intake, the radio has the wrong mounts and looks really crappy in there, I havent installed my AFR and oil temp gauges in yet (ran the signal wires just havent wired them in), it needs a paintjob, and a few other things. But the ultimate goal is to get a good tune on it. It will be a busy week...

I just wanted to pipe in and congratulate my son on getting this project to this point. Like he previously stated, he is 20 years old and this is the first time he has tried something like this. Sure, he had some help from other Nutmeg Clubmembers...turbo forum guys..and me. But..this is HIS project and has really done about 98% of the work himself. All the research..which amounts to countless hours...all the headwork was his labor with a bit of guidance on technique, but not much. The machine shop was very impressed with the work. The final tune is proving to be the difficult part...but he will get that done in due time.

I am extremely proud of what he has done with this...

Dad

Not only did I buy them, but I am still sporting these on my car! You should see them in one of the pictures on here haha

So I was recently having trouble with my LC-1. It was frustrating me to no end. It would give me weird signals: full rich directly switching to full lean over and over, or start off around 8-10 afr then switch to full lean as soon as it was under load. Lot of weird things. So I ended up pulling out all of the wiring, grounding it to a better spot, powering it through a better spot, and moving all of its wiring to the engine bay, and sure enough it worked just fine! Just ended up tucking it under the driver finder for now. And you will also see in one of the pictures I wrapped my downpipe. Seems to be keeping a lot of heat off of my heater hoses.

So it still needs needs a lot of work on the tune, and it will not be coming with me up to school (in upstate NY in winter time with all that salt) but it will be waiting for me when I get home! I couldnt resist taking a few pictures of it outside before I leave though.
