Thank you all for the input and the responses. This forum has by far been the most helpful and responsive one I have tried. All the research I had done was leading me to the Cosworth Head Gasket too, so I am glad to hear that many of you felt the same way about it. I need to decide on the right size next.

@]2eDeYe - That was exactly what I needed to know. The journals are all clean and the crank has just been sitting in the box. I will get it prepped for another week or so before I reassemble.

@
johnbureezu - The Cosworth logo was a pretty cool little bonus I thought too and most of the drift S13 builders I spoke to have pointed me in that direction. They have some of the most experience with these engines because they use to pop them into their S13 Silvias before the big $ and big HP sponsorships came through. I started researching management and tuning. It is pretty intimidating to say the least. Standalone seemed like a waste considering my application. Greddy has E-Manage, but I have heard some horror stories there. Whatever I ultimately decide, it is going to be a piggyback system that I can later tweak via a laptop. How do you like the 4828? What HP are you working with and how is the low end throttle response??

@DISLEXICDIME - I hope so man, I hope so. I feel so far away from that time that it makes me sad.

@ariascarlos1990 - Sorry my friend, going 4 door, but I love me some goon.

@dennis - Thank you for all of the help man. Cosworth is clearly unanimous it seems.

Received my Blow-By Assembly Pipe for the block. It was one of two left in the US according to my dealership, but the size of this tube isn't the same as as the JDM versiong, but I seriously doubt that this will be a problem.
Posted Image

Here is a side-by-side comparison. It looks like the new version is made out of a different material too. Interesting. I wonder if this was a JDM versus USDM thing or just an upgrade.
Posted Image

Here are the two random pipes/tubes that I still need. The FSM does not specifically address these parts and it is a pain in the assets to try and figure out what they are. I guess I can clean the one on the right, but the one on the left I had to destroy to get out of the block.
Posted Image

Also picked up a revised chain guide. My old one wasn't broken, but it just seemed so cheap when compared to the old plastic one. The new metal variant is a lot stronger and tougher feeling.
Posted Image

Here is a comparison shot. Take special note, the old chain side guide uses different bolts, so make sure who ever you get yours from gives you the new hardware too.

Taking pistons, pins, rings, main/rod & thrust bearings, and rocker arms in this week for WPC. Buying cams and engine assembly lube and I shoudl be set to put her together. Still need a top mount tubro manifold, turbo, and thinking about a new OEM timing chain. Then I am moving on to the fuel deliver system and transmission. Need top feed injectors, Walbro 255, oh and a CAR FML!!!! I have to things to complain about:

First, I called GReddy to inquire why they have discontinued a lot of parts for the SR20DET and the reference was that the engine was too old. Not a direct quote, but it was definitely inferred. They are focusing their business on newer engine performance it would seem. Which does nothing but piss me off because I have truly enjoyed my experience learning how to work on an engine and it would not have been possible if it were not for the SR which has been done and documented by the tuner community. What other engine besides an RB can you get so much information on????

Hey everyone!!! Been doing a lot of searching for a 4 door Nickle Dime for the engine and trying to get a body to fit this monster in to. That combined with two practices a day and running the companies doesn't leave a lot of time for working on the engine.

My daily, the 745 is starting to have some transmission kick, needs new brakes, and has a slight coolant leak. I am beginning to question whether or not I should be picking up a new car to replace her too. Argh!!!! Expenses in the adult world suck.

I am hoping to finish paint preparation on the block this weekend and shoot it with some high-heat engine enamel. Until then I managed to track down the requisite 30mm freeze / core /expansion plugs. I was going to go OEM, but they tried to charge me $3 each at the $tealership. I really haven't had a good reliable dealership experience yet and it is really unfortunate because I am a big buyer, I pay cash, and I am loyal. I digress.

Posted Image

Anyone have any tips for spray painting the block?? I am very nervous about making my clean build look really bad and I have no spray paint experience...

Yo!!! What it do??? or How have you been?? for those of you without the Hip-Hop music influence. I have had an interesting couple of weeks since we last spoke. I went to BMW to get a quote for new brakes and rotors on the 745i, the $tealership quoted me a stupid dollar amount and I went ahead and did it myself. All OEM parts and 2 hours later I was done for a much more acceptable $175 price tag. Suck it BMW!!! Next weekend I am going to get her up on jack stands again and find that pesky coolant leak I suspect is from the $tealership not putting a hose back on right after a radiator fluid flush. Arg!!!!

Been a while since new parts arrived, but I was glad to see my new dipstick (perverts are allowed to laugh) come in. I inadvertently broke the old one during engine break down. I know, I know, it takes a special guy to screw that one up...
Posted Image

Next I was off to prep the engine block for paint. Dupli-Color Heat Heat Ceramic Engine Enamel in Cast Aluminum for that OEM feel. Since this was my first every experience with spray paint or painting in general I figured I might was well spend as much time in prep as I could... Hard to screw up as badly that way..

Engine block left to dry and I figured since I am feeling uber productive, I will takle that upper oil pain.. oops I mean pan
Posted Image

Cleaned and prepped for paint.. yes sir!!! Who is your sr20det daddy????
Posted Image

A shot of her back side (and the innuendo continues...)
Posted Image

Being as anal as I am, I wasn't 100% happy with the quality of my paint work. I couldn't get all the last bits of debris off of the block even after a dip in a whirlpool bath and scrubbing with copper brush. But I did do it all myself and I learned a lot. This will not be a show car, I plan on driving her. I do; however, want to keep this car clean and pretty after all of this hard work... flame away you professional engine painters.. I am open to hearing the good and bad...

Just wanted it to look pretty really. I dipped it and had it cleaned at the machine shop, but the head and the block came out two different shades of dirty looking. I decided I would scrub them with brass brushes, but that didn't help too much. Ultimately wound up spraying them to get the aesthetics I was hoping for. Is it bad to paint them? I have seen a lot of blocks done this way too. Let me know your thoughts my friend.

Why did you paint a aluminum block?


they do tarnish quite badly and those sr blocks are porous its super hard to scrub the dirt off them, I spent SEVERAL and by several I mean probably 10-12 hours scrubbing every nook and cranny from my sr block, degreaser, wire brush, aluminum brightener, rinse repeat, over and over and over. I could see how painting it would help with future cleaning . That aluminum stains so easily.

I bought a disco potato for my Sr build. It's the 86 ar though. I'm expecting 300 whp. I did nismo 555cc side feed injectors, greedy intake manifold, greedy pulleys, top mount tubular exhaust manifold, z32 maf fidanza flywheel and exedy stage 2 clutch. I also kinda overkilled my Sr for such a light car as a 510. Can't wait to see the finished outcome.

When I went to the machine shop to pick up my block and head I saw a few CA blocks that had been either painted or powder coated black. They looked pretty awesome. Made me wish I didn't have the urge to do it all myself and to learn.

Such a good segue too... When I went by the machine shop to pick up my block there was a recently worked on SR block that had been painted a gloss black. It looked cool, but what really stood out to me were the new shiny brass freeze plugs. I had always planned on replacing the ones in my block, but was unclear on two important details. First, I was not sure how important or not the work would really be, but I did like the aesthetics. And second, I heard a million and one different ways to get these little bad boys in. There seems to be a pretty even divide as to whether or not you should use sealant or not.

You remember where we last left off??? Here is the intake side still fresh from my DIY paint and partially covered in tape. I removed the tape covering my old freeze plugs. Note how the don't shine like new and are screaming for love and affection...

Let's just be honest with ourselves. I am not a mechanic. If you recall from the start of this thread, I have no idea what I am doing until after I read and read and read some more. To make up for my lack of mechanical precision I chose the liquid gasket route. After some research, I went with Permatex Aviation. $7 for a little added security and comfort in how badly I suck at hammering these in straight is pretty cheap if you ask me.
Posted Image

Smashing one edge and you get it to tilt... YAY!!!!
Posted Image

Out.... oooooh, look at all that coolant residue... interesting... Anyone know if this is a problem and or concern?? Is there a system flush I can do that would help remove some or all of this??
Posted Image

OEM old plug versus new aftermarket plug... Dorman plug kicks OEM's rear on shiny factor...
Posted Image

In this shot you can tell that the OEM is a little thicker with slightly longer side walls.. not sure if this is a problem or not, I'm going to go ahead an assume the answer is no. Mainly because I don't want to have to pull these all out now...
Posted Image

Bang! Bang! Pow! Pow! New plugs in...
Posted Image

Long distance shot....
Posted Image

Flip, time to repeat... 3 this time...
Posted Image

I had been somewhat conflicted as to whether or not I should have done this. Freeze plug problems or leaks are so rare from what I have read. But then this little guy popped out. I knew there was a problem as soon as I tried to flip it in the block. My screwdriver went through it. The rust and corossion was so bad that I am absolutely certain that at some point it woud have leaked. I guess it really was worth it in the end huh?
Posted Image

All done!!!!!
Posted Image

Up close...
Posted Image

I spent the rest of the afternoon getting the parts together to send off to WPC this week and cleaning the garage which had become quite dirty since paint and the brake job. I bought some used GReddy S13 sr20det cam gears last week. One I have those and a dipstick tube, I should be ready for assembly.

Looks good . A littke trick I learnd is when you pressure wash your engine do it where there is air. Get a air chuck put in ear plugs and blow all the water off of the aluminum you will be amazed how much cleaner it will look.

I really like what you have going on here. It is really nice seeing such attention paid to detail, and the best way to learn is by doing. I appreciate your humor and willingness to not only ask for opinions, but consider them as well.

I am a huge fan of painting the engine to look nice. Really helps so much in the long run! Check out my build thread (77 longbox) and check out my paint work. I use basecoat/clearcoat auto paint on every block I have painted and it has turned out wonderful.....Funny thing at a car show last weekend I saw a 420A turbo block I had painted 5 years ago and it still looked amazing!!

Keep up the good work!

Okay, sounds good. I only had one guy insist on pumping my ass in Oregon. That was along the Columbia river. The rest of the time, I just hopped out and started pumping, no one said shit.



New England is strange.  Every thing good is "Wicked". Nice cars are "mint". A truck canopy is a "cap" and a tonneau is a "lid".  Losing your khakis has a whole different meaning.

yeah, the SR is a very porous block and will suck up oil/grime in a heartbeat. This is why I painted mine as well.

Am I being a little too anal and slow with posting? I assumed that the mass amount of photos would help me later putting it all back together and I hoped that it may help someone else someday... Only a few more and we are up to date...
Posted Image

I don't understand why there is such a massive amount of oil/dirt sludge here... but my OCD will not let it stand.... ugh, F my life...
Posted Image

Not perfect, but this is where I wrapped for the night...
Posted Image

Oh and more GReddy goodies arrived, Rocker Arm Stoppers (RAS). Always use protection kids...
Posted Image

Z32 MAF on the way, OEM JDM Nissan gasket kit and DVD from drifting dot com already paid for and en route. I am planning on working the intake and exhaust sides, but am 50/50 on internal work. I ordered the DVD to gauge whether or not I think I can or should do it. The internals don't look that bad and I am only looking for approximately 400hp. I know I will need an AFC unit. Do I go with GReddy E-Manage or a standalone like the APEXi Neo??? There is so much to learn and know, I have a whole new respect for engine builders, this is complicated. Posted Image


the pic of the sludge removal reminds me of myself. i dont even like soot building up in my exhaust ports let alone some stray oil around typically oily parts. all my gunk has been on there for 35 years as well so its a blast.

@dennis - Hello again my friend. Picked up a dremel and waiting on the polish bits to come in and going to try to follow in your footsteps and make some things shiny. Also picked up a 320 grit one too. Should be interesting. No dime yet, still looking for a good 4 door candidate. I am getting eager though and may settle soon.

@josh_t - Yeah, I don't like anything being dirty or out of place. The OCD in me is going to have a difficult time adjusting to this engine running, being driven frequently and actually having some dirt around.

@wana510 - Nice setup!! Are you running the .64 or .85 AR?? I want to stick with the T25 flanges and go .64, but the local shop guys have been trying to get me to go with the bigger mouth.

@darcToken - Thanks man, that is why I have fallen in love with this forum. People seem to genuinely want to help and be interested. The interaction and wealth of information really are priceless to a guy like me who is still trying to learn.

Flickr has been blocked by the office, so photos to come soon. Picked up discontinued GReddy cam sprockets, new oil dipstick tube/guide, and a 87mm bore .04 Cometic head gasket. I have a standard bore engine at 86mm, but this seems to be the size that everyone suggested after researching for a while.

As soon as I pick my parts up from WPC treatment, I am ready to reassemble!!!! WOW!! I almost can't believe I said that. But I do need a turbo and a top mount manifold and tubing etc. Anyone have any recommendations??? Also my biggest fear is going to be running the tubes on the engine. Any good points of reference??

Not a huge update, but I prepped the head for paint....

Exhaust side.... you can see how dirty it is here...

And finally the nasty intake side... obviously you can begin to see why I found it necessary to paint the head and block... this simply will not due...

Oh and the newly arrived parts for your visual pleasure...

Discontinued GReddy cam gears/sprockets... these were not easy to find....
Posted Image

Cometic head gasket.. 87mm @ 0.40 thickness.. Is it that big of a deal if my machine shop guy said to go OEM factory thickness because he barely took anything off on the deck job??
Posted Image

And last, but not least, my new dipstick guide/tube. Because I am a dipstick and screwed mine up for no reason other than sheer frustration trying to remove it.. Argh!!
Posted Image

Wish me luck kids... moving on to the painting of the block and the polishing of the aluminum bits while I let my wallet recover for a while.... Has anyone else noted how much polishing aluminum is likely to cause cancer or is it just me??
